The country has never had an official religion either as a republic or as a kingdom. In the 20th century, the clergy of all faiths was weakened under the monarchy and ultimately eradicated during the 1950s and 1960s, under the state policy of obliterating all organised religion from the territories of Albania. The communist regime persecuted and suppressed religious observance and institutions and entirely banned religion. The country was then officially declared to be the world's first atheist state. Religious freedom has returned, however, since the end of communism. + +Islam survived communist era persecution and reemerged in the modern era as a practised religion in Albania. Some smaller Christian sects in Albania include Evangelicals and several Protestant communities including Seventh-day Adventist Church, Church of Jesus Christ of Latter-day Saints and Jehovah's Witnesses. The first recorded Protestant of Albania was Said Toptani, who travelled around Europe and returned to Tirana in 1853, where he preached Protestantism. The first evangelical Protestants appeared in the 19th century and the Evangelical Alliance was founded in 1892. Nowadays, it has 160 member congregations from different Protestant denominations. Following mass emigration to Israel after the fall of communism, there are only 200 Albanian Jews left in the country. + +Culture + +Symbols + +The red and black national colours are displayed on the flag of Albania that is adorned with a double-headed eagle as the foremost recognised national symbol of Albania. With the black eagle portraying bravery and strength, the red field symbolises the fortitude and sacrifices of the Albanian people. The eagle is linked with the legacy of the national hero Gjergj Kastrioti, renowned as Skanderbeg, who led a prosperous resistance movement against Ottoman rule. Rooted in the Middle Ages, it emerged as a heraldic symbol in the Principality of Arbër and among notable Albanian dynasties such as the Dukagjini, Kastrioti, Muzaka and Thopia clans. Amid the Albanian Renaissance, marking the resurgence of Albanian national identity and aspirations for independence, the Albanian eagle regained its prominence. Its importance reached its culmination with Albania's declaration of independence in 1912, when Ismail Qemali raised it as the national flag in Vlorë. + +The coat of arms of Albania is an adaptation of the flag of Albania and the seal of Skanderbeg. The coat comprises the black double-headed eagle positioned at the center of a red field. Above the eagle, it carries the helmet of Skanderbeg that is crowned with the head of a golden horned goat. , which translates to "You Albania, give me honor, give me the name Albanian", is the national motto of Albania. It finds its foundation in the legacy of national poet Naim Frashëri, who held a renowned role during the Albanian Renaissance. The national anthem of Albania, "", was composed by Asdreni and adopted as such following Albania's independence in 1912. + +Clothing + +Albanian traditional clothing, with its contrasting variations for the northern Gheg and southern Tosk Albanians, is a testament to Albania's history, cultural diversity and ethnic identity. Gheg men wear a light-colored shirt paired with wide loose-fitting trousers referred to as the Tirq. These trousers are securely fastened by a wide woven belt, the Brez. An integral component of their costume is the Xhamadan, a woolen red velvet vest adorned with folkloric motifs and gold patterns. They also wear a distinctive dome-shaped hat known as the Qeleshe, crafted from wool, with its origins tracing back to the Illyrians. Conversely, Tosk men opt for the Fustanella, a knee-length garment designated as the national costume, typically white with pleats, accompanied by a white shirt. They also wear a beige or dark blue Xhamadan reminiscent of the Gheg attire. To complete their attire, men wear knee-high socks referred to as Çorape and leather shoes known as Opinga. + +The attire of Gheg and Tosk women is renowned for its rich palette of colors and intricate filigree detailing, displayed across various components including ear ornaments, finger rings, necklaces, belt buckles and buttons. Key components include a long, light-toned shirt paired with an apron, often accompanied by a woolen or felt mantle referred to as the Xhoka. Additional upper garments, such as the Dollama or Mintan, may be layered, along with a headscarf known as Kapica or Shall. A distinctive variation incorporates a pair of aprons, including the Pështjellak at the rear and the Paranik at the front. Integral to the traditional attire of Gheg women is the ancient Xhubleta. Dedicated efforts have been undertaken to preserve and promote the dress, acknowledging its significance as an emblem of Albanian heritage. As a testament to its importance, the Xhubleta has been inscribed on the UNESCO Intangible Cultural Heritage List. The distinctive bell-shaped garment is fashioned in black and enriched with embroidered ethnic Albanian motifs, showcasing the remarkable craftsmanship of northern Albania. Its crafting process involves multiple intricate stages, encompassing the preparation of shajak fabric and the precise cutting techniques. + +Art and architecture + +The artistic history of Albania has been particularly influenced by a multitude of ancient and medieval people, traditions and religions. It covers a broad spectrum with mediums and disciplines that include painting, pottery, sculpture, ceramics and architecture all of them exemplifying a great variety in style and shape, in different regions and period. + +The rise of the Byzantine and Ottoman Empire in the Middle Ages was accompanied by a corresponding growth in Christian and Islamic art in the lands of Albania which are apparent in examples of architecture and mosaics throughout the country. Centuries later, the Albanian Renaissance proved crucial to the emancipation of the modern Albanian culture and saw unprecedented developments in all fields of literature and art whereas artists sought to return to the ideals of Impressionism and Romanticism. However, Onufri, Kolë Idromeno, David Selenica, Kostandin Shpataraku and the Zografi Brothers are the most eminent representatives of Albanian art. + +The architecture of Albania reflects the legacy of various civilisations tracing back to the classical antiquity. Major cities in Albania have evolved from within the castle to include dwellings, religious and commercial structures, with constant redesigning of town squares and evolution of building techniques. Nowadays, the cities and towns reflect a whole spectrum of various architectural styles. In the 20th century, many historical as well as sacred buildings bearing the ancient influence were demolished during the communist era. + +Ancient architecture is found throughout Albania and most visible in Byllis, Amantia, Phoenice, Apollonia, Butrint, Antigonia, Shkodër and Durrës. Considering the long period of rule of the Byzantine Empire, they introduced castles, citadels, churches and monasteries with spectacular wealth of visible murals and frescos. Perhaps the best known examples can be found in the southern Albanian cities and surroundings of Korçë, Berat, Voskopojë and Gjirokastër. Involving the introduction of Ottoman architecture there was a development of mosques and other Islamic buildings, particularly seen in Berat and Gjirokastër. + +A productive period of Historicism, Art Nouveau and Neoclassicism merged into the 19th century, best exemplified in Korçë. The 20th century brought new architectural styles such as the modern Italian style, which is present in Tirana such as the Skanderbeg Square and Ministries. It is also present in Shkodër, Vlorë, Sarandë and Durrës. Moreover, other towns received their present-day Albania-unique appearance through various cultural or economic influences. + +Socialist classicism arrived during the communist era in Albania after the Second World War. At this period many socialist-styled complexes, wide roads and factories were constructed, while town squares were redesigned and numerous of historic and important buildings demolished. Notable examples of that style include the Mother Teresa Square, Pyramid of Tirana, Palace of Congresses and so on. + +Three Albanian archaeological sites are included in the list of UNESCO World Heritage Sites. These include the ancient remains of Butrint, the medieval Historic Centres of Berat and Gjirokastër, and Natural and Cultural Heritage of the Ohrid region site shared with North Macedonia since 2019. Furthermore, the royal Illyrian tombs, the remains of Apollonia, the ancient Amphitheatre of Durrës and the Fortress of Bashtovë has been included on the tentative list of Albania. + +Cuisine + +Throughout the centuries, Albanian cuisine has been widely influenced by Albanian culture, geography and history, and as such, different parts of the country enjoy specific regional cuisines. Cooking traditions especially vary between the north and the south, owing to differing topography and climate that essentially contribute to the excellent growth conditions for a wide array of herbs, fruits, and vegetables. + +Albanians produce and use many varieties of fruits such as lemons, oranges, figs, and most notably, olives, which are perhaps the most important element of Albanian cooking. Spices and other herbs such as basil, lavender, mint, oregano, rosemary, and thyme are widely used, as are vegetables such as garlic, onions, peppers, potatoes, tomatoes, as well as legumes of all types. + +With a coastline along the Adriatic and Ionian in the Mediterranean Sea, fish, crustaceans, and seafood are a popular and an integral part of the Albanian diet. Otherwise, lamb is the traditional meat for different holidays and religious festivals for both Christians and Muslims, although poultry, beef, and pork are also in plentiful supply. + +Tavë kosi ("soured milk casserole") is the national dish of Albania, consisting of lamb and rice baked under a thick, tart veil of yoghurt. Fërgesë is another national dish, made up of peppers, tomatoes, and cottage cheese. Pite is also popular, a baked pastry with a filling of a mixture of spinach and gjizë (curd) or mish (ground meat). + +Petulla, a traditional fried dough, is also a popular speciality, and is served with powdered sugar or feta cheese and different sorts of fruit jams. Flia consists of multiple crêpe-like layers brushed with cream and served with sour cream. Krofne, similar to Berliner doughnuts, are filled with jam, or chocolate and often eaten during winter. + +Coffee is an integral part of the Albanian lifestyle. The country has more coffee houses per capita than any other country in the world. Tea is also enjoyed both at home or outside at cafés, bars, or restaurants. Çaj Mali (Sideritis tea) is enormously beloved, and a part of the daily routine for most Albanians. It is cultivated across Southern Albania and noted for its medicinal properties. Black tea is also popular. + +Albanian wine is also common throughout the country, and has been cultivated for thousands of years. Albania has a long and ancient history of wine production, and belongs to the Old World of wine producing countries. + +Music + +Albanian folk music is a prominent part of the national identity, and continues to play a major part in overall Albanian music. Folk music can be divided into two stylistic groups, mainly the northern Gheg varieties, and southern Lab and Tosk varieties. Northern and southern traditions are contrasted by a rugged tone from the north, and the more relaxed southern form of music. + +Many songs concern events from Albanian history and culture, including traditional themes of honour, hospitality, treachery, and revenge. The first compilation of Albanian folk music was made by two Himariot musicians, Neço Muka and Koço Çakali, in Paris, during their work with Albanian soprano Tefta Tashko-Koço. Several gramophone compilations were recorded at the time by the three artists, which eventually led to the recognition of Albanian iso-polyphony as a UNESCO Intangible Cultural Heritage. + + is a traditional Albanian song contest organised by the national broadcaster Radio Televizioni Shqiptar (RTSH). The festival is celebrated annually since its inauguration in 1962 and has launched the careers of some of Albania's most successful singers including Vaçe Zela and Parashqevi Simaku. It is significantly a music competition among Albanian performers presenting unreleased songs in premiere, composed by Albanian authors and voted by juries or by public. + +Contemporary artists Rita Ora, Bebe Rexha, Era Istrefi, Dua Lipa, Ava Max, Bleona, Elvana Gjata, Ermonela Jaho, and Inva Mula have achieved international recognition for their music, while soprano Ermonela Jaho has been described by some as the "world's most acclaimed soprano". Albanian opera singer Saimir Pirgu was nominated for the 2017 Grammy Award. + +Literature + +The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications. The Protestant reforms invigorated hopes for the development of the local language and literary tradition, when cleric Gjon Buzuku translated the Catholic liturgy into Albanian, trying to do for Albanian what Martin Luther had done for German. Meshari (The Missal) written by Gjon Buzuku was published in 1555 and is considered one of the first literary work of written Albanian during the Middle Ages. The refined level of the language and the stabilised orthography must be the result of an earlier tradition of written Albanian, a tradition that is not well understood. However, there is some fragmented evidence, pre-dating Buzuku, which indicates that Albanian was written from at least the 14th century. + +Albanian writings from these centuries must not have been religious texts only, but historical chronicles too. They are mentioned by the humanist Marin Barleti, who in his book Siege of Shkodër (Rrethimi i Shkodrës) from 1504, confirms that he leafed through such chronicles written in the language of the people (in vernacula lingua) as well as his famous biography of Skanderbeg Historia de vita et gestis Scanderbegi Epirotarum principis (History of Skanderbeg) from 1508. The History of Skanderbeg is still the foundation of Skanderbeg studies and is considered an Albanian cultural treasure, vital to the formation of Albanian national self-consciousness. + +During the 16th and the 17th centuries, the catechism (E mbësuame krishterë) (Christian Teachings) from 1592 written by Lekë Matrënga, (Doktrina e krishterë) (The Christian Doctrine) from 1618 and (Rituale romanum) 1621 by Pjetër Budi, the first writer of original Albanian prose and poetry, an apology for George Castriot (1636) by Frang Bardhi, who also published a dictionary and folklore creations, the theological-philosophical treaty Cuneus Prophetarum (The Band of Prophets) (1685) by Pjetër Bogdani, the most universal personality of Albanian Middle Ages, were published in Albanian. The most famous Albanian writer in the 20th and 21st century is probably Ismail Kadare. + +Sports + +Albania participated at the Olympic Games in 1972 for the first time. The country made their Winter Olympic Games debut in 2006. Albania missed the next four games, two of them due to the 1980 and 1984 boycotts, but returned for the 1992 games in Barcelona. Since then, Albania have participated in all games. Albania normally competes in events that include swimming, athletics, weightlifting, shooting and wrestling. The country have been represented by the National Olympic Committee of Albania since 1972. The nation has participated at the Mediterranean Games since the games of 1987 in Syria. The Albanian athletes have won a total of 43 (8 gold, 17 silver and 18 bronze) medals from 1987 to 2013. + +Popular sports in Albania include football, weightlifting, basketball, volleyball, tennis, swimming, rugby union and gymnastics. Football is by far the most popular sport in Albania. It is governed by the Football Association of Albania (, F.SH.F.), which has membership in FIFA and UEFA. + +The Albania national football team, ranking 51st in the World in 2017 (highest 22nd on 22 August 2015) have won the 1946 Balkan Cup and the Malta Rothmans International Tournament 2000, but had never participated in any major UEFA or FIFA tournament, until UEFA Euro 2016, Albania's first ever appearance at the continental tournament and at a major men's football tournament. Albania scored their first ever goal in a major tournament and secured their first ever win in European Championship when they beat Romania by 1–0 in a UEFA Euro 2016 match on 19 June 2016. The most successful football clubs are Skënderbeu, KF Tirana, Dinamo Tirana, Partizani and Vllaznia. + +Weightlifting is one of the most successful individual sport for the Albanians, with the national team winning medals at the European Weightlifting Championships and the rest international competitions. Albanian weightlifters have won a total of 16 medals at the European Championships with 1 of them being gold, 7 silver and 8 bronze. In the World Weightlifting Championships, the Albanian weightlifting team has won in 1972 a gold in 2002 a silver and in 2011 a bronze medal. + +Diaspora + +Historically, the Albanian people have established several communities in many regions throughout Southern Europe. The Albanian diaspora has been formed since the late Middle Ages, when they emigrated to places such as Italy, especially in Sicily and Calabria, and Greece to escape either various socio-political difficulties or the Ottoman conquest of Albania. Following the fall of communism, large numbers of Albanians have migrated to countries such as Australia, Canada, France, Germany, Greece, Italy, Scandinavia, Switzerland, the United Kingdom and the United States. Albanian minorities are present in the neighbouring territories such as the west of North Macedonia, the east of Montenegro, Kosovo in its entirety and southern Serbia. In Kosovo, Albanians are the largest ethnic group in the country. Altogether, the number of ethnic Albanians living abroad is estimated to be higher than the total population inside Albania. + +See also + Outline of Albania + Bibliography of Albania + +Notes + +References + +Further reading + + History of the Party of Labor of Albania.

In the English language, the word generally refers to God in Islam. The word is thought to be derived by contraction from al-ilāh, which means "the god", and is linguistically related to the Aramaic words Elah and Syriac (ʼAlāhā) and the Hebrew word El (Elohim) for God. + +The word Allah has been used by Arabic people of different religions since pre-Islamic times. The pre-Islamic Arabs worshipped a supreme deity whom they called Allah, alongside other lesser deities. Muhammad used the word Allah to indicate the Islamic conception of God. Allah has been used as a term for God by Muslims (both Arab and non-Arab), Judaeo-Arabic-speaking Jews, and Arab Christians after the term "al-ilāh" and "Allah" were used interchangeably in Classical Arabic by the majority of Arabs who had become Muslims. It is also often, albeit not exclusively, used in this way by Bábists, Baháʼís, Mandaeans, Indonesian and Maltese Christians, and Sephardi Jews, as well as by the Gagauz people. Similar usage by Christians and Sikhs in Peninsular Malaysia has recently led to political and legal controversies. + +Etymology + +The etymology of the word Allāh has been discussed extensively by classical Arab philologists. Grammarians of the Basra school regarded it as either formed "spontaneously" (murtajal) or as the definite form of lāh (from the verbal root lyh with the meaning of "lofty" or "hidden"). Others held that it was borrowed from Syriac or Hebrew. + +Most considered it to be derived from a contraction of the Arabic definite article al- "the" and "deity, god" to meaning "the deity, the God". Indeed, there is "the interchangeability of al-ilāh and allāh in early Arabic poetry even when composed by the Christian ʿAdī ibn Zayd". + +The majority of modern scholars subscribe to the latter theory, and view the loanword hypothesis with skepticism. + +The use of "Allah" as the name of a deity appears as early as the first century. An inscription using the Ancient South Arabian script in Old Arabic from Qaryat al-Fāw reads, "'to Kahl and lh and ʿAththar' (b-khl w-lh w-ʿṯr)". + +Cognates of the name "Allāh" exist in other Semitic languages, including Hebrew and Aramaic. The corresponding Aramaic form is ʼElāh (), but its emphatic state is (). It is written as () in Biblical Aramaic and () in Syriac as used by the Assyrian Church, both meaning simply "God". The unusual Syriac form is likely an imitation of the Arabic. + +History of usage + +Pre-Islamic Arabians + +Regional variants of the word Allah occur in both pagan and Christian pre-Islamic inscriptions. Different theories have been proposed regarding the role of Allah in pre-Islamic polytheistic cults. According to the Islamic scholar Ibn Kathir, Arab pagans considered Allah as an unseen God who created and controlled the Universe. Pagans believed worship of humans or animals who had lucky events in their life brought them closer to God. Pre-Islamic Meccans worshiped Allah alongside a host of lesser gods and those whom they called the "daughters of Allah." Islam forbade worship of anyone or anything other than God. Some authors have suggested that polytheistic Arabs used the name as a reference to a creator god or a supreme deity of their pantheon. The term may have been vague in the Meccan religion. According to one hypothesis, which goes back to Julius Wellhausen, Allah (the supreme deity of the tribal federation around Quraysh) was a designation that consecrated the superiority of Hubal (the supreme deity of Quraysh) over the other gods. However, there is also evidence that Allah and Hubal were two distinct deities. According to that hypothesis, the Kaaba was first consecrated to a supreme deity named Allah and then hosted the pantheon of Quraysh after their conquest of Mecca, about a century before the time of Muhammad. Some inscriptions seem to indicate the use of Allah as a name of a polytheist deity centuries earlier, but nothing precise is known about this use. Some scholars have suggested that Allah may have represented a remote creator god who was gradually eclipsed by more particularized local deities. There is disagreement on whether Allah played a major role in the Meccan religious cult. No iconic representation of Allah is known to have existed. Allah is the only god in Mecca that did not have an idol. Muhammad's father's name was meaning "the slave of Allāh". + +Islam + +In Islam, Allah is the unique, omnipotent and only deity and creator of the universe and is equivalent to God in other Abrahamic religions. Allah is usually seen as the personal name of God, a notion which became disputed in contemporary scholarship, including the question, whether or not the word Allah should be translated as God. + +According to Islamic belief, Allah is the most common word to represent God, and humble submission to his will, divine ordinances and commandments is the pivot of the Muslim faith. "He is the only God, creator of the universe, and the judge of humankind." "He is unique () and inherently one (), all-merciful and omnipotent." No human eyes can see Allah till the Day Of Judgement. The Qur'an declares "the reality of Allah, His inaccessible mystery, His various names, and His actions on behalf of His creatures." Allah does not depend on anything. God is not a part of the Christian Trinity. God has no parents and no children. + +The concept correlates to the Tawhid, where chapter 112 of the Qur'an (Al-'Ikhlās, The Sincerity) reads:۝ SAY, God is one GOD; +۝ the eternal GOD: +۝ He begetteth not, neither is He begotten: +۝ and there is not any one like unto Him.and in the Ayat ul-Kursi ("Verse of the Throne"), which is the 255th verse and the powerful verse in the longest chapter (the 2nd chapter) of the Qur'an, Al-Baqarah ("The Cow") states: + +Allah! There is no deity but Him, the Alive, the Eternal. +Neither slumber nor sleep overtaketh Him. + +Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. +Who could intercede in His presence without His permission? + +He knoweth that which is in front of them and that which is behind them, +while they encompass nothing of His knowledge except what He wills. + +His throne includeth the heavens and the earth, +and He is never weary of preserving them. + +He is the Sublime, the Tremendous. + +In Islamic tradition, there are 99 Names of God ( lit. meaning: 'the best names' or 'the most beautiful names'), each of which evoke a distinct characteristic of Allah. All these names refer to Allah, the supreme and all-comprehensive divine name. Among the 99 names of God, the most famous and most frequent of these names are "the Merciful" (ar-Raḥmān) and "the Compassionate" (), including the forementioned above al-Aḥad ("the One, the Indivisible") and al-Wāḥid ("the Unique, the Single"). + +Most Muslims use the untranslated Arabic phrase (meaning 'if God wills') after references to future events. Muslim discursive piety encourages beginning things with the invocation of (meaning 'In the name of God'). There are certain phrases in praise of God that are favored by Muslims, including "" (Glory be to God), "" (Praise be to God), "" (There is no deity but God) or sometimes "lā ilāha illā inta/ huwa" (There is no deity but You/ Him) and "" (God is the Most Great) as a devotional exercise of remembering God (dhikr). + +In a Sufi practice known as dhikr Allah (Arabic: ذكر الله, lit. "Remembrance of God"), the Sufi repeats and contemplates the name Allah or other associated divine names to Him while controlling his or her breath. For example, in countless references in the context from the Qur'an forementioned above: + + Allah is referred to in the second person pronoun in Arabic as "Anta (Arabic: أَنْتَ)" like the English "You", or commonly in the third person pronoun "Huwa (Arabic: َهُو)" like the English "He" and uniquely in the case pronoun of the oblique form "Hu/ Huw (Arabic: هو /-هُ)" like the English "Him" which rhythmically resonates and is chanted as considered a sacred sound or echo referring Allah as the "Absolute Breath or Soul of Life"—Al-Nafs al-Hayyah (Arabic: النّفس الحياة, an-Nafsu 'l-Ḥayyah)—notably among the 99 names of God, "the Giver of Life" (al-Muḥyī) and "the Bringer of Death" (al-Mumiyt); + Allah is neither male or female (who has no gender), but who is the essence of the "Omnipotent, Selfless, Absolute Soul (an-Nafs, النّفس) and Holy Spirit" (ar-Rūḥ, الرّوح) - notably among the 99 names of God, "the All-Holy, All-Pure and All-Sacred" (al-Quddus); + Allah is the originator of both before and beyond the cycle of creation, destruction and time, - notably among the 99 names of God, "the First, Beginning-less" (al-Awwal), "the End/ Beyond ["the Final Abode"]/ Endless" (al-Akhir/ al-Ākhir) and "the Timeless" (aṣ-Ṣabūr). + +According to Gerhard Böwering, in contrast with pre-Islamic Arabian polytheism, God in Islam does not have associates and companions, nor is there any kinship between God and jinn. Pre-Islamic pagan Arabs believed in a blind, powerful, inexorable and insensible fate over which man had no control. This was replaced with the Islamic notion of a powerful but provident and merciful God. + +According to Francis Edward Peters, "The Qur’ān insists, Muslims believe, and historians affirm that Muhammad and his followers worship the same God as the Jews (). The Qur’an's Allah is the same Creator God who covenanted with Abraham". Peters states that the Qur'an portrays Allah as both more powerful and more remote than Yahweh, and as a universal deity, unlike Yahweh who closely follows Israelites. + +Christianity +The Christian Arabs of today have no other word for "God" than "Allah". Similarly, the Aramaic word for "God" in the language of Assyrian Christians is ʼĔlāhā, or Alaha. (Even the Arabic-descended Maltese language of Malta, whose population is almost entirely Catholic, uses Alla for "God".) Arab Christians, for example, use the terms () for God the Father, () for God the Son, and () for God the Holy Spirit. (See God in Christianity for the Christian concept of God.) + +Arab Christians have used two forms of invocations that were affixed to the beginning of their written works. They adopted the Muslim , and also created their own Trinitized as early as the 8th century. The Muslim reads: "In the name of God, the Compassionate, the Merciful." The Trinitized reads: "In the name of Father and the Son and the Holy Spirit, One God." The Syriac, Latin and Greek invocations do not have the words "One God" at the end. This addition was made to emphasize the monotheistic aspect of Trinitarian belief and also to make it more palatable to Muslims. + +According to Marshall Hodgson, it seems that in the pre-Islamic times, some Arab Christians made pilgrimage to the Kaaba, a pagan temple at that time, honoring Allah there as God the Creator. + +Some archaeological excavation quests have led to the discovery of ancient pre-Islamic inscriptions and tombs made by Arab Christians in the ruins of a church at Umm el-Jimal in Northern Jordan, which initially, according to Enno Littman (1949), contained references to Allah as the proper name of God. However, on a second revision by Bellamy et al. (1985 & 1988) the 5-versed-inscription was re-translated as "(1)This [inscription] was set up by colleagues of ʿUlayh, (2) son of ʿUbaydah, secretary (3) of the cohort Augusta Secunda (4) Philadelphiana; may he go mad who (5) effaces it." + +The syriac word ܐܠܗܐ (ʼĔlāhā) can be found in the reports and the lists of names of Christian martyrs in South Arabia, as reported by antique Syriac documents of the names of those martyrs from the era of the Himyarite and Aksumite kingdoms + +In Ibn Ishaq's biography there is a Christian leader named Abd Allah ibn Abu Bakr ibn Muhammad, who was martyred in Najran in 523, as he had worn a ring that said "Allah is my lord". + +In an inscription of Christian martyrion dated back to 512, references to 'l-ilah (الاله) can be found in both Arabic and Aramaic. The inscription starts with the statement "By the Help of 'l-ilah". + +In pre-Islamic Gospels, the name used for God was "Allah", as evidenced by some discovered Arabic versions of the New Testament written by Arab Christians during the pre-Islamic era in Northern and Southern Arabia. However most recent research in the field of Islamic Studies by Sydney Griffith et al. (2013), David D. Grafton (2014), Clair Wilde (2014) & ML Hjälm et al. (2016 & 2017) assert that "all one can say about the possibility of a pre-Islamic, Christian version of the Gospel in Arabic is that no sure sign of its actual existence has yet emerged." Additionally ML Hjälm in her most recent research (2017) inserts that "manuscripts containing translations of the gospels are encountered no earlier than the year 873" + +Irfan Shahîd quoting the 10th-century encyclopedic collection Kitab al-Aghani notes that pre-Islamic Arab Christians have been reported to have raised the battle cry "Ya La Ibad Allah" (O slaves of Allah) to invoke each other into battle. According to Shahid, on the authority of 10th-century Muslim scholar Al-Marzubani, "Allah" was also mentioned in pre-Islamic Christian poems by some Ghassanid and Tanukhid poets in Syria and Northern Arabia. + +Pronunciation + +The word Allāh is generally pronounced , exhibiting a heavy lām, , a velarized alveolar lateral approximant, a marginal phoneme in Modern Standard Arabic. Since the initial alef has no hamza, the initial is elided when a preceding word ends in a vowel. If the preceding vowel is , the lām is light, , as in, for instance, the Basmala. + +As a loanword + +English and other European languages +The history of the name Allāh in English was probably influenced by the study of comparative religion in the 19th century; for example, Thomas Carlyle (1840) sometimes used the term Allah but without any implication that Allah was anything different from God. However, in his biography of Muḥammad (1934), Tor Andræ always used the term Allah, though he allows that this "conception of God" seems to imply that it is different from that of the Jewish and Christian theologies. + +Languages which may not commonly use the term Allah to denote God may still contain popular expressions which use the word. For example, because of the centuries long Muslim presence in the Iberian Peninsula, the word in the Spanish language and in the Portuguese language exist today, borrowed from Andalusi Arabic similar to (). This phrase literally means 'if God wills' (in the sense of "I hope so"). The German poet Mahlmann used the form "Allah" as the title of a poem about the ultimate deity, though it is unclear how much Islamic thought he intended to convey. + +Some Muslims leave the name "Allāh" untranslated in English, rather than using the English translation "God". The word has also been applied to certain living human beings as personifications of the term and concept. + +Malaysian and Indonesian language + +Christians in Malaysia and Indonesia use to refer to God in the Malaysian and Indonesian languages (both of them standardized forms of the Malay language). Mainstream Bible translations in the language use as the translation of Hebrew (translated in English Bibles as "God"). This goes back to early translation work by Francis Xavier in the 16th century. The first dictionary of Dutch-Malay by Albert Cornelius Ruyl, Justus Heurnius, and Caspar Wiltens in 1650 (revised edition from 1623 edition and 1631 Latin edition) recorded " as the translation of the Dutch word . Ruyl also translated the Gospel of Matthew in 1612 into the Malay language (an early Bible translation into a non-European language, +made a year after the publication of the King James Version), which was printed in the Netherlands in 1629. Then he translated the Gospel of Mark, published in 1638. + +The government of Malaysia in 2007 outlawed usage of the term in any other but Muslim contexts, but the Malayan High Court in 2009 revoked the law, ruling it unconstitutional. While had been used for the Christian God in Malay for more than four centuries, the contemporary controversy was triggered by usage of by the Roman Catholic newspaper The Herald. The government appealed the court ruling, and the High Court suspended implementation of its verdict until the hearing of the appeal. In October 2013 the court ruled in favor of the government's ban. In early 2014 the Malaysian government confiscated more than 300 bibles for using the word to refer to the Christian God in Peninsular Malaysia. However, the use of is not prohibited in the two Malaysian states of Sabah and Sarawak. The main reason it is not prohibited in these two states is that usage has been long-established and local Alkitab (Bibles) have been widely distributed freely in East Malaysia without restrictions for years. Both states also do not have similar Islamic state laws as those in West Malaysia. + +In reaction to some media criticism, the Malaysian government has introduced a "10-point solution" to avoid confusion and misleading information. The 10-point solution is in line with the spirit of the 18- and 20-point agreements of Sarawak and Sabah. + +National flags with "Allah" written on them + +Typography + +The word is always written without an to spell the vowel.

It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia (Republic of Dagestan) to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city. + +The Azerbaijan Democratic Republic proclaimed its independence from the Transcaucasian Democratic Federative Republic in 1918 and became the first secular democratic Muslim-majority state. In 1920, the country was incorporated into the Soviet Union as the Azerbaijan SSR. The modern Republic of Azerbaijan proclaimed its independence on 30 August 1991, shortly before the dissolution of the Soviet Union in the same year. In September 1991, the ethnic Armenian majority of the Nagorno-Karabakh region formed the self-proclaimed Republic of Artsakh. The region and seven surrounding districts are internationally recognized as part of Azerbaijan, pending a solution to the status of Nagorno-Karabakh through negotiations facilitated by the OSCE, although it became de facto independent with the end of the First Nagorno-Karabakh War in 1994. Following the Second Nagorno-Karabakh War in 2020, the seven districts and parts of Nagorno-Karabakh were returned to Azerbaijani control. + +Azerbaijan is a unitary semi-presidential republic. It is one of six independent Turkic states and an active member of the Organization of Turkic States and the TÜRKSOY community. Azerbaijan has diplomatic relations with 182 countries and holds membership in 38 international organizations, including the United Nations, the Council of Europe, the Non-Aligned Movement, the OSCE, and the NATO PfP program. It is one of the founding members of GUAM, the CIS, and the OPCW. Azerbaijan is also an observer state of the WTO. + +The vast majority of the country's population (97%) is nominally Muslim, but the constitution does not declare an official religion and all major political forces in the country are secular. Azerbaijan is a developing country and ranks 91st on the Human Development Index. It has a high rate of economic development and literacy, and a low rate of unemployment. However, the ruling New Azerbaijan Party, in power since 1993, has been accused of authoritarian leadership under the leadership of both Heydar Aliyev and his son Ilham Aliyev, and deteriorating the country's human rights record, including increasing restrictions on civil liberties, particularly on press freedom and political repression. + +Etymology + +According to a modern etymology, the term Azerbaijan derives from that of Atropates, a Persian satrap under the Achaemenid Empire, who was later reinstated as the satrap of Media under Alexander the Great. The original etymology of this name is thought to have its roots in the once-dominant Zoroastrianism. In the Avesta's Frawardin Yasht ("Hymn to the Guardian Angels"), there is a mention of , which literally translates from Avestan as "we worship the fravashi of the holy Atropatene". The name "Atropates" itself is the Greek transliteration of an Old Iranian, probably Median, compounded name with the meaning "Protected by the (Holy) Fire" or "The Land of the (Holy) Fire". The Greek name was mentioned by Diodorus Siculus and Strabo. Over the span of millennia, the name evolved to (Middle Persian), then to , , (New Persian) and present-day Azerbaijan. + +The name Azerbaijan was first adopted for the area of the present-day Republic of Azerbaijan by the government of Musavat in 1918, after the collapse of the Russian Empire, when the independent Azerbaijan Democratic Republic was established. Until then, the designation had been used exclusively to identify the adjacent region of contemporary northwestern Iran, while the area of the Azerbaijan Democratic Republic was formerly referred to as Arran and Shirvan. On that basis Iran protested the newly adopted country name. + +During Soviet rule, the country was also spelled in Latin from the Russian transliteration as (). The country's name was also spelled in Cyrillic script from 1940 to 1991 as . + +History + +Antiquity + +The earliest evidence of human settlement in the territory of Azerbaijan dates back to the late Stone Age and is related to the Guruchay culture of Azykh Cave. + +Early settlements included the Scythians during the 9th century BC. Following the Scythians, Iranian Medes came to dominate the area to the south of the Aras river. The Medes forged a vast empire between 900 and 700 BC, which was integrated into the Achaemenid Empire around 550 BC. The area was conquered by the Achaemenids leading to the spread of Zoroastrianism. + +From the Sasanid period to the Safavid period + +The Sasanian Empire turned Caucasian Albania into a vassal state in 252, while King Urnayr officially adopted Christianity as the state religion in the 4th century. Despite Sassanid rule, Albania remained an entity in the region until the 9th century, while fully subordinate to Sassanid Iran, and retained its monarchy. Despite being one of the chief vassals of the Sasanian emperor, the Albanian king had only a semblance of authority, and the Sasanian marzban (military governor) held most civil, religious, and military authority. + +In the first half of the 7th century, Caucasian Albania, as a vassal of the Sasanians, came under nominal Muslim rule due to the Muslim conquest of Persia. The Umayyad Caliphate repulsed both the Sasanians and Byzantines from the South Caucasus and turned Caucasian Albania into a vassal state after Christian resistance led by King Javanshir was suppressed in 667. The power vacuum left by the decline of the Abbasid Caliphate was filled by numerous local dynasties such as the Sallarids, Sajids, and Shaddadids. At the beginning of the 11th century, the territory was gradually seized by the waves of Oghuz Turks from Central Asia, who adopted a Turkoman ethnonym at the time. The first of these Turkic dynasties established was the Seljuk Empire, which entered the area now known as Azerbaijan by 1067. + +The pre-Turkic population that lived on the territory of modern Azerbaijan spoke several Indo-European and Caucasian languages, among them Armenian and an Iranian language, Old Azeri, which was gradually replaced by a Turkic language, the early precursor of the Azerbaijani language of today. Some linguists have also stated that the Tati dialects of Iranian Azerbaijan and the Republic of Azerbaijan, like those spoken by the Tats, are descended from Old Azeri. +Locally, the possessions of the subsequent Seljuk Empire were ruled by Eldiguzids, technically vassals of the Seljuk sultans, but sometimes de facto rulers themselves. Under the Seljuks, local poets such as Nizami Ganjavi and Khaqani gave rise to a blossoming of Persian literature on the territory of present-day Azerbaijan. + +The local dynasty of the Shirvanshahs became a vassal state of Timur's empire and assisted him in his war with the ruler of the Golden Horde Tokhtamysh. Following Timur's death, two independent and rival states emerged: Qara Qoyunlu and Aq Qoyunlu. The Shirvanshahs returned, maintaining for numerous centuries to come a high degree of autonomy as local rulers and vassals as they had done since 861. In 1501, the Safavid dynasty of Iran subdued the Shirvanshahs and gained its possessions. In the course of the next century, the Safavids converted the formerly Sunni population to Shia Islam, as they did with the population in what is modern-day Iran. The Safavids allowed the Shirvanshahs to remain in power, under Safavid suzerainty, until 1538, when Safavid king Tahmasp I (r. 1524–1576) completely deposed them, and made the area into the Safavid province of Shirvan. The Sunni Ottomans briefly managed to occupy present-day Azerbaijan as a result of the Ottoman–Safavid War of 1578–1590; by the early 17th century, they were ousted by Safavid Iranian ruler Abbas I (r. 1588–1629). In the wake of the demise of the Safavid Empire, Baku and its environs were briefly occupied by the Russians as a consequence of the Russo-Persian War of 1722–1723. Remainder of present Azerbaijan was occupied by the Ottomans from 1722 to 1736. Despite brief intermissions such as these by Safavid Iran's neighboring rivals, the land of what is today Azerbaijan remained under Iranian rule from the earliest advent of the Safavids up to the course of the 19th century. + +Modern history + +After the Safavids, the area was ruled by the Iranian Afsharid dynasty. After the death of Nader Shah (r. 1736–1747), many of his former subjects capitalized on the eruption of instability. Numerous self-ruling khanates with various forms of autonomy emerged in the area. The rulers of these khanates were directly related to the ruling dynasties of Iran and were vassals and subjects of the Iranian shah. The khanates exercised control over their affairs via international trade routes between Central Asia and the West. + +Thereafter, the area was under the successive rule of the Iranian Zands and Qajars. From the late 18th century, Imperial Russia switched to a more aggressive geo-political stance towards its two neighbors and rivals to the south, namely Iran and the Ottoman Empire. Russia now actively tried to gain possession of the Caucasus region which was, for the most part, in the hands of Iran. In 1804, the Russians invaded and sacked the Iranian town of Ganja, sparking the Russo-Persian War of 1804–1813. The militarily superior Russians ended the Russo-Persian War of 1804–1813 with a victory. + +Following Qajar Iran's loss in the 1804–1813 war, it was forced to concede suzerainty over most of the khanates, along with Georgia and Dagestan to the Russian Empire, per the Treaty of Gulistan. + +The area to the north of the river Aras, amongst which territory lies the contemporary Republic of Azerbaijan, was Iranian territory until Russia occupied it in the 19th century. About a decade later, in violation of the Gulistan treaty, the Russians invaded Iran's Erivan Khanate. This sparked the final bout of hostilities between the two, the Russo-Persian War of 1826–1828. The resulting Treaty of Turkmenchay, forced Qajar Iran to cede sovereignty over the Erivan Khanate, the Nakhchivan Khanate and the remainder of the Talysh Khanate, comprising the last parts of the soil of the contemporary Azerbaijani Republic that were still in Iranian hands. After the incorporation of all Caucasian territories from Iran into Russia, the new border between the two was set at the Aras River, which, upon the Soviet Union's disintegration, subsequently became part of the border between Iran and the Azerbaijan Republic. + +Qajar Iran was forced to cede its Caucasian territories to Russia in the 19th century, which thus included the territory of the modern-day Azerbaijan Republic, while as a result of that cession, the Azerbaijani ethnic group is nowadays parted between two nations: Iran and Azerbaijan. + +Despite the Russian conquest, throughout the entire 19th century, preoccupation with Iranian culture, literature, and language remained widespread amongst Shia and Sunni intellectuals in the Russian-held cities of Baku, Ganja and Tiflis (Tbilisi, now Georgia). Within the same century, in post-Iranian Russian-held East Caucasia, an Azerbaijani national identity emerged at the end of the 19th century. + +After the collapse of the Russian Empire during World War I, the short-lived Transcaucasian Democratic Federative Republic was declared, constituting the present-day republics of Azerbaijan, Georgia, and Armenia. +It was followed by the March Days massacres that took place between 30 March and 2 April 1918 in the city of Baku and adjacent areas of the Baku Governorate of the Russian Empire. When the republic dissolved in May 1918, the leading Musavat party declared independence as the Azerbaijan Democratic Republic (ADR), adopting the name of "Azerbaijan" for the new republic; a name that prior to the proclamation of the ADR was solely used to refer to the adjacent northwestern region of contemporary Iran. The ADR was the first modern parliamentary republic in the Muslim world. Among the important accomplishments of the Parliament was the extension of suffrage to women, making Azerbaijan the first Muslim nation to grant women equal political rights with men. Another important accomplishment of ADR was the establishment of Baku State University, which was the first modern-type university founded in the Muslim East. + +By March 1920, it was obvious that Soviet Russia would attack Baku. Vladimir Lenin said that the invasion was justified as Soviet Russia could not survive without Baku's oil. Independent Azerbaijan lasted only 23 months until the Bolshevik 11th Soviet Red Army invaded it, establishing the Azerbaijan SSR on 28 April 1920. Although the bulk of the newly formed Azerbaijani army was engaged in putting down an Armenian revolt that had just broken out in Karabakh, Azerbaijanis did not surrender their brief independence of 1918–20 quickly or easily. As many as 20,000 Azerbaijani soldiers died resisting what was effectively a Russian reconquest. Within the ensuing early Soviet period, the Azerbaijani national identity was finally forged. + +On 13 October 1921, the Soviet republics of Russia, Armenia, Azerbaijan, and Georgia signed an agreement with Turkey known as the Treaty of Kars. The previously independent Republic of Aras would also become the Nakhchivan Autonomous Soviet Socialist Republic within the Azerbaijan SSR by the treaty of Kars. On the other hand, Armenia was awarded the region of Zangezur and Turkey agreed to return Gyumri (then known as Alexandropol). + +During World War II, Azerbaijan played a crucial role in the strategic energy policy of the Soviet Union, with 80 percent of the Soviet Union's oil on the Eastern Front being supplied by Baku. By the Decree of the Supreme Soviet of the USSR in February 1942, the commitment of more than 500 workers and employees of the oil industry of Azerbaijan were awarded orders and medals. Operation Edelweiss carried out by the German Wehrmacht targeted Baku because of its importance as the energy (petroleum) dynamo of the USSR. A fifth of all Azerbaijanis fought in the Second World War from 1941 to 1945. Approximately 681,000 people with over 100,000 of them women, went to the front, while the total population of Azerbaijan was 3.4 million at the time. Some 250,000 people from Azerbaijan were killed on the front. More than 130 Azerbaijanis were named Heroes of the Soviet Union. Azerbaijani Major-General Azi Aslanov was twice awarded the Hero of the Soviet Union. + +Independence + +Following the politics of glasnost, initiated by Mikhail Gorbachev, civil unrest and ethnic strife grew in various regions of the Soviet Union, including Nagorno-Karabakh, an autonomous region of the Azerbaijan SSR. The disturbances in Azerbaijan, in response to Moscow's indifference to an already heated conflict, resulted in calls for independence and secession, which culminated in the Black January events in Baku. Later in 1990, the Supreme Council of the Azerbaijan SSR dropped the words "Soviet Socialist" from the title, adopted the "Declaration of Sovereignty of the Azerbaijan Republic" and restored the flag of the Azerbaijan Democratic Republic as the state flag. As a consequence of the failed 1991 Soviet coup d'état attempt in Moscow, the Supreme Council of Azerbaijan adopted a Declaration of Independence on 18 October 1991, which was affirmed by a nationwide referendum in December 1991, while the Soviet Union officially ceased to exist on 26 December 1991. The country now celebrates its Independence Day on 18 October. + +The early years of independence were overshadowed by the First Nagorno-Karabakh war with the ethnic Armenian majority of Nagorno-Karabakh backed by Armenia. By the end of the hostilities in 1994, Armenians controlled up to 14–16 percent of Azerbaijani territory, including Nagorno-Karabakh itself. During the war many atrocities and pogroms by both sides were committed including the massacres at Malibeyli and Gushchular, the Garadaghly massacre and the Khojaly massacres, along with the Baku pogrom, the Maraga massacre and the Kirovabad pogrom. Furthermore, an estimated 30,000 people have been killed and more than a million people have been displaced, more than 800,000 Azerbaijanis and 300,000 Armenians. Four United Nations Security Council Resolutions (822, 853, 874, and 884) demand for "the immediate withdrawal of all Armenian forces from all occupied territories of Azerbaijan." Many Russians and Armenians left and fled Azerbaijan as refugees during the 1990s. According to the 1970 census, there were 510,000 ethnic Russians and 484,000 Armenians in Azerbaijan. + +Aliyev family rule, 1993–present + +In 1993, democratically elected president Abulfaz Elchibey was overthrown by a military insurrection led by Colonel Surat Huseynov, which resulted in the rise to power of the former leader of Soviet Azerbaijan, Heydar Aliyev. In 1994, Surat Huseynov, by that time the prime minister, attempted another military coup against Heydar Aliyev, but he was arrested and charged with treason. A year later, in 1995, another coup was attempted against Aliyev, this time by the commander of the OMON special unit, Rovshan Javadov. The coup was averted, resulting in the killing of the latter and disbanding of Azerbaijan's OMON units. At the same time, the country was tainted by rampant corruption in the governing bureaucracy. In October 1998, Aliyev was reelected for a second term. + +Ilham Aliyev, Heydar Aliyev's son, became chairman of the New Azerbaijan Party as well as President of Azerbaijan when his father died in 2003. He was reelected to a third term as president in October 2013. In April 2018, President Ilham Aliyev secured his fourth consecutive term in the election that was boycotted by the main opposition parties as fraudulent. On 27 September 2020, new clashes in the unresolved Nagorno-Karabakh conflict resumed along the Nagorno-Karabakh Line of Contact. Both the armed forces of Azerbaijan and Armenia reported military and civilian casualties. The Nagorno-Karabakh ceasefire agreement and the end of the six-week war between Azerbaijan and Armenia was widely celebrated in Azerbaijan, as they made significant territorial gains. Despite the much improved economy, particularly with the exploitation of the Azeri–Chirag–Guneshli oil field and Shah Deniz gas field, the Aliyev family rule has been criticized due to election fraud, high levels of economic inequality and domestic corruption. + +Geography + +Geographically, Azerbaijan is located in the South Caucasus region of Eurasia, straddling Western Asia and Eastern Europe. It lies between latitudes 38° and 42° N, and longitudes 44° and 51° E. The total length of Azerbaijan's land borders is , of which are with Armenia, with Iran, 480 kilometers with Georgia, with Russia and with Turkey. The coastline stretches for , and the length of the widest area of the Azerbaijani section of the Caspian Sea is . The country has a landlocked exclave, the Nakhchivan Autonomous Republic. + +Three physical features dominate Azerbaijan: the Caspian Sea, whose shoreline forms a natural boundary to the east; the Greater Caucasus mountain range to the north; and the extensive flatlands at the country's center. There are also three mountain ranges, the Greater and Lesser Caucasus, and the Talysh Mountains, together covering approximately 40% of the country. The highest peak of Azerbaijan is Mount Bazardüzü , while the lowest point lies in the Caspian Sea . Nearly half of all the mud volcanoes on Earth are concentrated in Azerbaijan, these volcanoes were also among nominees for the New 7 Wonders of Nature. + +The main water sources are surface waters. Only 24 of the 8,350 rivers are greater than in length. All the rivers drain into the Caspian Sea in the east of the country. The largest lake is Sarysu , and the longest river is Kur , which is transboundary with Armenia. Azerbaijan has several islands along the Caspian sea, mostly located in the Baku Archipelago. + +Since the independence of Azerbaijan in 1991, the Azerbaijani government has taken measures to preserve the environment of Azerbaijan. National protection of the environment accelerated after 2001 when the state budget increased due to new revenues provided by the Baku–Tbilisi–Ceyhan pipeline. Within four years, protected areas doubled and now make up eight percent of the country's territory. Since 2001 the government has set up seven large reserves and almost doubled the sector of the budget earmarked for environmental protection. + +Landscape + +Azerbaijan is home to a wide variety of landscapes. Over half of Azerbaijan's landmass consists of mountain ridges, crests, highlands, and plateaus which rise up to hypsometric levels of 400–1000 meters (including the Middle and Lower lowlands), in some places (Talis, Jeyranchol-Ajinohur and Langabiz-Alat foreranges) up to 100–120 meters, and others from 0–50 meters and up (Qobustan, Absheron). The rest of Azerbaijan's terrain consists of plains and lowlands. Hypsometric marks within the Caucasus region vary from about −28 meters at the Caspian Sea shoreline up to 4,466 meters (Bazardüzü peak). + +The formation of climate in Azerbaijan is influenced particularly by cold arctic air masses of Scandinavian anticyclone, temperate air masses of Siberian anticyclone, and Central Asian anticyclone. Azerbaijan's diverse landscape affects the ways air masses enter the country. The Greater Caucasus protects the country from direct influences of cold air masses coming from the north. That leads to the formation of subtropical climate on most foothills and plains of the country. Meanwhile, plains and foothills are characterized by high solar radiation rates. + +Nine out of eleven existing climate zones are present in Azerbaijan. Both the absolute minimum temperature ( ) and the absolute maximum temperature were observed in Julfa and Ordubad – regions of Nakhchivan Autonomous Republic. The maximum annual precipitation falls in Lankaran () and the minimum in Absheron (). + +Rivers and lakes form the principal part of the water systems of Azerbaijan, they were formed over a long geological timeframe and changed significantly throughout that period. This is particularly evidenced by remnants of ancient rivers found throughout the country. The country's water systems are continually changing under the influence of natural forces and human-introduced industrial activities. Artificial rivers (canals) and ponds are a part of Azerbaijan's water systems. In terms of water supply, Azerbaijan is below the average in the world with approximately per year of water per square kilometer. All big water reservoirs are built on Kur. The hydrography of Azerbaijan basically belongs to the Caspian Sea basin. + +The Kura and Aras are the major rivers in Azerbaijan. They run through the Kura-Aras Lowland. The rivers that directly flow into the Caspian Sea, originate mainly from the north-eastern slope of the Major Caucasus and Talysh Mountains and run along the Samur–Devechi and Lankaran lowlands. + +Yanar Dag, translated as "burning mountain", is a natural gas fire which blazes continuously on a hillside on the Absheron Peninsula on the Caspian Sea near Baku, which itself is known as the "land of fire." Flames jet out into the air from a thin, porous sandstone layer. It is a tourist attraction to visitors to the Baku area. + +Biodiversity + +The first reports on the richness and diversity of animal life in Azerbaijan can be found in travel notes of Eastern travelers. Animal carvings on architectural monuments, ancient rocks, and stones survived up to the present times. The first information on flora and fauna of Azerbaijan was collected during the visits of naturalists to Azerbaijan in the 17th century. + +There are 106 species of mammals, 97 species of fish, 363 species of birds, 10 species of amphibians, and 52 species of reptiles which have been recorded and classified in Azerbaijan. The national animal of Azerbaijan is the Karabakh horse, a mountain-steppe racing and riding horse endemic to Azerbaijan. The Karabakh horse has a reputation for its good temper, speed, elegance, and intelligence. It is one of the oldest breeds, with ancestry dating to the ancient world, but today the horse is an endangered species. + +Azerbaijan's flora consists of more than 4,500 species of higher plants. Due to the unique climate in Azerbaijan, the flora is much richer in the number of species than the flora of the other republics of the South Caucasus. 66 percent of the species growing in the whole Caucasus can be found in Azerbaijan. The country lies within four ecoregions: Caspian Hyrcanian mixed forests, Caucasus mixed forests, Eastern Anatolian montane steppe, and Azerbaijan shrub desert and steppe. Azerbaijan had a 2018 Forest Landscape Integrity Index mean score of 6.55/10, ranking it 72nd globally out of 172 countries. + +Government and politics + +Azerbaijan's government functions as an authoritarian regime in practice; although it regularly holds elections, these are marred by electoral fraud and other unfair election practices. Azerbaijan has been ruled by the Aliyev political family and the New Azerbaijan Party (Yeni Azərbaycan Partiyası, YAP) established by Heydar Aliyev continuously since 1993. It is categorised as "not free" by Freedom House, who ranked it 9/100 on Global Freedom Score in 2022, calling it a "consolidated authoritarian regime". + +The structural formation of Azerbaijan's political system was completed by the adoption of the new Constitution on 12 November 1995. According to Article 23 of the Constitution, the state symbols of the Azerbaijan Republic are the flag, the coat of arms, and the national anthem. The state power in Azerbaijan is limited only by law for internal issues, but international affairs are also limited by international agreements' provisions. + +The Constitution of Azerbaijan states that it is a presidential republic with three branches of power – Executive, Legislative, and Judicial. The legislative power is held by the unicameral National Assembly and the Supreme National Assembly in the Nakhchivan Autonomous Republic. The Parliament of Azerbaijan, called Milli Majlis, consists of 125 deputies elected based on majority vote, with a term of five years for each elected member. The elections are held every five years, on the first Sunday of November. The Parliament is not responsible for the formation of the government, but the Constitution requires the approval of the Cabinet of Ministers by Milli Majlis. The New Azerbaijan Party, and independents loyal to the ruling government, currently hold almost all of the Parliament's 125 seats. During the 2010 Parliamentary election, the opposition parties, Musavat and Azerbaijani Popular Front Party, failed to win a single seat. European observers found numerous irregularities in the run-up to the election and on election day. + +The executive power is held by the President, who is elected for a seven-year term by direct elections, and the Prime Minister. The president is authorized to form the Cabinet, a collective executive body accountable to both the President and the National Assembly. The Cabinet of Azerbaijan consists primarily of the prime minister, his deputies, and ministers. The 8th Government of Azerbaijan is the administration in its current formation. The president does not have the right to dissolve the National Assembly but has the right to veto its decisions. To override the presidential veto, the parliament must have a majority of 95 votes. The judicial power is vested in the Constitutional Court, Supreme Court, and the Economic Court. The president nominates the judges in these courts. + +Azerbaijan's system of governance nominally can be called two-tiered. The top or highest tier of the government is the Executive Power headed by President. The President appoints the Cabinet of Ministers and other high-ranking officials. The Local Executive Authority is merely a continuation of Executive Power. The Provision determines the legal status of local state administration in Azerbaijan on Local Executive Authority (Yerli Icra Hakimiyati), adopted 16 June 1999. In June 2012, the President approved the new Regulation, which granted additional powers to Local Executive Authorities, strengthening their dominant position in Azerbaijan's local affairs The Security Council is the deliberative body under the president, and he organizes it according to the Constitution. It was established on 10 April 1997. The administrative department is not a part of the president's office but manages the financial, technical and pecuniary activities of both the president and his office. + +Foreign relations + +The short-lived Azerbaijan Democratic Republic succeeded in establishing diplomatic relations with six countries, sending diplomatic representatives to Germany and Finland. The process of international recognition of Azerbaijan's independence from the collapsing Soviet Union lasted roughly one year. The most recent country to recognize Azerbaijan was Bahrain, on 6 November 1996. Full diplomatic relations, including mutual exchanges of missions, were first established with Turkey, Pakistan, the United States, Iran and Israel. Azerbaijan has placed a particular emphasis on its "special relationship" with Turkey. + +Azerbaijan has diplomatic relations with 158 countries so far and holds membership in 38 international organizations. It holds observer status in the Non-Aligned Movement and World Trade Organization and is a correspondent at the International Telecommunication Union. + +On 9 May 2006 Azerbaijan was elected to membership in the newly established Human Rights Council by the United Nations General Assembly. The term of office began on 19 June 2006. Azerbaijan was first elected as a non-permanent member of the UN Security Council in 2011 with the support of 155 countries. + +Foreign policy priorities of Azerbaijan include, first of all, the restoration of its territorial integrity; elimination of the consequences of occupation of Nagorno-Karabakh and seven other regions of Azerbaijan surrounding Nagorno-Karabakh; integration into European and Euro-Atlantic structure; contribution to international security; cooperation with international organizations; regional cooperation and bilateral relations; strengthening of defense capability; promotion of security by domestic policy means; strengthening of democracy; preservation of ethnic and religious tolerance; scientific, educational, and cultural policy and preservation of moral values; economic and social development; enhancing internal and border security; and migration, energy, and transportation security policy. + +Azerbaijan is an active member of international coalitions fighting international terrorism, and was one of the first countries to offer support after the September 11 attacks. The country is an active member of NATO's Partnership for Peace program, contributing to peacekeeping efforts in Kosovo, Afghanistan and Iraq. Azerbaijan is also a member of the Council of Europe since 2001 and maintains good relations with the European Union. The country may eventually apply for EU membership. + + + +On 1 July 2021, the US Congress advanced legislation that will have an impact on the military aid that Washington has sent to Azerbaijan since 2012. This was due to the fact that the packages to Armenia, instead, are significantly smaller. + +Azerbaijan has been harshly criticized for bribing foreign officials and diplomats to promote its causes abroad and legitimize its elections at home, a practice termed caviar diplomacy. The Azerbaijani laundromat money laundering operation involved the bribery of foreign politicians and journalists to serve the Azerbaijani government's public relations interests. + +Military + +The history of the modern Azerbaijan army dates back to Azerbaijan Democratic Republic in 1918 when the National Army of the newly formed Azerbaijan Democratic Republic was created on 26 June 1918. When Azerbaijan gained independence after the dissolution of the Soviet Union, the Armed Forces of the Republic of Azerbaijan were created according to the Law on the Armed Forces of 9 October 1991. The original date of the establishment of the short-lived National Army is celebrated as Army Day (26 June) in today's Azerbaijan. +As of 2021, Azerbaijan had 126,000 active personnel in its armed forces. There are also 17,000 paramilitary troops and 330,00 reserve personnel. The armed forces have three branches: the Land Forces, the Air Forces and the Navy. Additionally the armed forces embrace several military sub-groups that can be involved in state defense when needed. These are the Internal Troops of the Ministry of Internal Affairs and the State Border Service, which includes the Coast Guard as well. The Azerbaijan National Guard is a further paramilitary force. It operates as a semi-independent entity of the Special State Protection Service, an agency subordinate to the President. + +Azerbaijan adheres to the Treaty on Conventional Armed Forces in Europe and has signed all major international arms and weapons treaties. Azerbaijan closely cooperates with NATO in programs such as Partnership for Peace and Individual Partnership Action Plan/pfp and ipa. Azerbaijan has deployed 151 of its Peacekeeping Forces in Iraq and another 184 in Afghanistan. + +Azerbaijan spent $2.24 billion on its defence budget , which amounted to 5.4% of its total GDP, and some 12.7% of general government expenditure. Azerbaijani defense industry manufactures small arms, artillery systems, tanks, armors and night vision devices, aviation bombs, UAV'S/unmanned aerial vehicle, various military vehicles and military planes and helicopters. + +Administrative divisions + +Azerbaijan is administratively divided into 14 economic regions; 66 rayons (, singular ) and 11 cities (, singular ) under the direct authority of the republic. Moreover, Azerbaijan includes the Autonomous Republic () of Nakhchivan. The President of Azerbaijan appoints the governors of these units, while the government of Nakhchivan is elected and approved by the parliament of Nakhchivan Autonomous Republic. + +Economy + +After gaining independence in 1991, Azerbaijan became a member of the International Monetary Fund, the World Bank, the European Bank for Reconstruction and Development, the Islamic Development Bank, and the Asian Development Bank. The banking system of Azerbaijan consists of the Central Bank of Azerbaijan, commercial banks, and non-banking credit organizations. The National (now Central) Bank was created in 1992 based on the Azerbaijan State Savings Bank, an affiliate of the former State Savings Bank of the USSR. The Central Bank serves as Azerbaijan's central bank, empowered to issue the national currency, the Azerbaijani manat, and to supervise all commercial banks. Two major commercial banks are UniBank and the state-owned International Bank of Azerbaijan, run by Abbas Ibrahimov. + +Pushed up by spending and demand growth, the 2007 Q1 inflation rate reached 16.6%. Nominal incomes and monthly wages climbed 29% and 25% respectively against this figure, but price increases in the non-oil industry encouraged inflation. Azerbaijan shows some signs of the so-called "Dutch disease" because of its fast-growing energy sector, which causes inflation and makes non-energy exports more expensive. +In the early 2000s, chronically high inflation was brought under control. This led to the launch of a new currency, the new Azerbaijani manat, on 1 January 2006, to cement the economic reforms and erase the vestiges of an unstable economy. +Azerbaijan is also ranked 57th in the Global Competitiveness Report for 2010–2011, above other CIS countries. By 2012 the GDP of Azerbaijan had increased 20-fold from its 1995 level. + +Energy and natural resources + + +Two-thirds of Azerbaijan is rich in oil and natural gas. +The history of the oil industry of Azerbaijan dates back to the ancient period. Arabian historian and traveler Ahmad Al-Baladhuri discussed the economy of the Absheron peninsula in antiquity, mentioning its oil in particular. There are many pipelines in Azerbaijan. The goal of the Southern Gas Corridor, which connects the giant Shah Deniz gas field in Azerbaijan to Europe, is to reduce European Union's dependency on Russian gas. + +The region of the Lesser Caucasus accounts for most of the country's gold, silver, iron, copper, titanium, chromium, manganese, cobalt, molybdenum, complex ore and antimony. In September 1994, a 30-year contract was signed between the State Oil Company of Azerbaijan Republic (SOCAR) and 13 oil companies, among them Amoco, BP, ExxonMobil, Lukoil and Equinor. As Western oil companies are able to tap deepwater oilfields untouched by the Soviet exploitation, Azerbaijan is considered one of the most important spots in the world for oil exploration and development. Meanwhile, the State Oil Fund of Azerbaijan was established as an extra-budgetary fund to ensure macroeconomic stability, transparency in the management of oil revenue, and safeguarding of resources for future generations. + +Access to biocapacity in Azerbaijan is less than world average. In 2016, Azerbaijan had 0.8 global hectares of biocapacity per person within its territory, half the world average of 1.6 global hectares per person. In 2016 Azerbaijan used 2.1 global hectares of biocapacity per person – their ecological footprint of consumption. This means they use more biocapacity than Azerbaijan contains. As a result, Azerbaijan is running a biocapacity deficit. + +Azeriqaz, a sub-company of SOCAR, intends to ensure full gasification of the country by 2021. +Azerbaijan is one of the sponsors of the east–west and north–south energy transport corridors. Baku–Tbilisi–Kars railway line will connect the Caspian region with Turkey, which is expected to be completed in July 2017. The Trans-Anatolian gas pipeline (TANAP) and Trans Adriatic Pipeline (TAP) will deliver natural gas from Azerbaijan's Shah Deniz gas to Turkey and Europe. + +Azerbaijan extended the agreement on development of ACG until 2050 according to the amended PSA signed on 14 September 2017 by SOCAR and co-ventures (BP, Chevron, Inpex, Equinor, ExxonMobil, TP, ITOCHU and ONGC Videsh). + +Agriculture + +Azerbaijan has the largest agricultural basin in the region. About 54.9 percent of Azerbaijan is agricultural land. At the beginning of 2007 there were 4,755,100 hectares of utilized agricultural area. In the same year the total wood resources counted 136 million m3. Azerbaijan's agricultural scientific research institutes are focused on meadows and pastures, horticulture and subtropical crops, green vegetables, viticulture and wine-making, cotton growing and medicinal plants. In some areas it is profitable to grow grain, potatoes, sugar beets, cotton and tobacco. Livestock, dairy products, and wine and spirits are also important farm products. The Caspian fishing industry concentrates on the dwindling stocks of sturgeon and beluga. In 2002 the Azerbaijani merchant marine had 54 ships. + +Some products previously imported from abroad have begun to be produced locally. Among them are Coca-Cola by Coca-Cola Bottlers LTD., beer by Baki-Kastel, parquet by Nehir and oil pipes by EUPEC Pipe Coating Azerbaijan. + +Tourism + +Tourism is an important part of the economy of Azerbaijan. The country was a well-known tourist spot in the 1980s. The fall of the Soviet Union, and the First Nagorno-Karabakh War during the 1990s, damaged the tourist industry and the image of Azerbaijan as a tourist destination. + +It was not until the 2000s that the tourism industry began to recover, and the country has since experienced a high rate of growth in the number of tourist visits and overnight stays. + +In recent years, Azerbaijan has also become a popular destination for religious, spa, and health care tourism. During winter, the Shahdag Mountain Resort offers skiing with state of the art facilities. + +The government of Azerbaijan has set the development of Azerbaijan as an elite tourist destination as a top priority. It is a national strategy to make tourism a major, if not the single largest, contributor to the Azerbaijani economy. These activities are regulated by the Ministry of Culture and Tourism of Azerbaijan. + +There are 63 countries which have a visa-free score. +E-visa – for a visit of foreigners of visa-required countries to the Republic of Azerbaijan. + +According to the Travel and Tourism Competitiveness Report 2015 of the World Economic Forum, Azerbaijan holds 84th place. + +According to a report by the World Travel and Tourism Council, Azerbaijan was among the top ten countries showing the strongest growth in visitor exports between 2010 and 2016, In addition, Azerbaijan placed first (46.1%) among countries with the fastest-developing travel and tourism economies, with strong indicators for inbound international visitor spending last year. + +Transportation + +The convenient location of Azerbaijan on the crossroad of major international traffic arteries, such as the Silk Road and the south–north corridor, highlights the strategic importance of the transportation sector for the country's economy. The transport sector in the country includes roads, railways, aviation, and maritime transport. + +Azerbaijan is also an important economic hub in the transportation of raw materials. The Baku–Tbilisi��Ceyhan pipeline (BTC) became operational in May 2006 and extends more than through the territories of Azerbaijan, Georgia, and Turkey. The BTC is designed to transport up to 50 million tons of crude oil annually and carries oil from the Caspian Sea oilfields to global markets. The South Caucasus Pipeline, also stretching through the territory of Azerbaijan, Georgia, and Turkey, became operational at the end of 2006 and offers additional gas supplies to the European market from the Shah Deniz gas field. Shah Deniz is expected to produce up to 296 billion cubic meters of natural gas per year. Azerbaijan also plays a major role in the EU-sponsored Silk Road Project. + +In 2002, the Azerbaijani government established the Ministry of Transport with a broad range of policy and regulatory functions. In the same year, the country became a member of the Vienna Convention on Road Traffic. Priorities are upgrading the transport network and improving transportation services to better facilitate the development of other sectors of the economy. + +The 2012 construction of Kars–Tbilisi–Baku railway was meant to improve transportation between Asia and Europe by connecting the railways of China and Kazakhstan in the east to the European railway system in the west via Turkey. In 2010 Broad-gauge railways and electrified railways stretched for and respectively. By 2010, there were 35 airports and one heliport. + +Science and technology + +In the 21st century, a new oil and gas boom helped improve the situation in Azerbaijan's science and technology sectors. The government launched a campaign aimed at modernization and innovation. The government estimates that profits from the information technology and communication industry will grow and become comparable to those from oil production. + +Azerbaijan has a large and steadily growing Internet sector, mostly uninfluenced by the financial crisis of 2007–2008; rapid growth is forecast for at least five more years. Azerbaijan was ranked 89th in the Global Innovation Index in 2023. + +The country has also been making progress in developing its telecoms sector. The Ministry of Communications & Information Technologies (MCIT) and an operator through its role in Aztelekom are both policy-makers and regulators. Public payphones are available for local calls and require the purchase of a token from the telephone exchange or some shops and kiosks. Tokens allow a call of indefinite duration. , there were 1,397,000 main telephone lines and 1,485,000 internet users. There are four GSM providers: Azercell, , Azerfon (Nar Mobile), Nakhtel mobile network operators and one CDMA. + +In the 21st century a number of prominent Azerbaijani geodynamics and geotectonics scientists, inspired by the fundamental works of Elchin Khalilov and others, designed hundreds of earthquake prediction stations and earthquake-resistant buildings that now constitute the bulk of The Republican Center of Seismic Service. + +The Azerbaijan National Aerospace Agency launched its first satellite AzerSat 1 into orbit on 7 February 2013 from Guiana Space Centre in French Guiana at orbital positions 46° East. The satellite covers Europe and a significant part of Asia and Africa and serves the transmission of TV and radio broadcasting as well as the Internet. The launching of a satellite into orbit is Azerbaijan's first step in realizing its goal of becoming a nation with its own space industry, capable of successfully implementing more projects in the future. + +Demographics + +As of March 2022, 52.9% of Azerbaijan's total population of 10,164,464 is urban, with the remaining 47.1% being rural. In January 2019, the 50.1% of the total population was female. The sex ratio in the same year was 0.99 males per female. + +The 2011 population growth-rate was 0.85%, compared to 1.09% worldwide. A significant factor restricting population growth is a high level of migration. In 2011 Azerbaijan saw a migration of −1.14/1,000 people. + +The Azerbaijani diaspora is found in 42 countries and in turn there are many centers for ethnic minorities inside Azerbaijan, including the German cultural society "Karelhaus", Slavic cultural center, Azerbaijani-Israeli community, Kurdish cultural center, International Talysh Association, Lezgin national center "Samur", Azerbaijani-Tatar community, Crimean Tatars society, etc. + +In total, Azerbaijan has 78 cities, 63 city districts, and one special legal status city. 261 urban-type settlements and 4248 villages follow these. + +Ethnicity + +The ethnic composition of the population according to the 2009 population census: 91.6% Azerbaijanis, 2.0% Lezgins, 1.4% Armenians (almost all Armenians live in the break-away region of Nagorno-Karabakh), 1.3% Russians, 1.3% Talysh, 0.6% Avars, 0.4% Turks, 0.3% Tatars, 0.3% Tats, 0.2% Ukrainians, 0.1% Tsakhurs, 0.1% Georgians, 0.1% Jews, 0.1% Kurds, other 0.2%. + +Languages + +The official language is Azerbaijani, which is a Turkic language. Azerbaijani is spoken by approximately 92% of the population as a mother tongue. Russian and Armenian (only in Nagorno-Karabakh) are also spoken, and each are the mother tongue of around 1.5% of the population respectively. There are a dozen other minority languages spoken natively in the country. Avar, Budukh, Georgian, Juhuri, Khinalug, Kryts, Lezgin, Rutul, Talysh, Tat, Tsakhur, and Udi are all spoken by small minorities. Some of these language communities are very small and their numbers are decreasing. Armenian was the majority language in Nagorno-Karabakh with around 76% in 1989. After the first Nagorno-Karabakh war, the population is almost exclusively Armenian at around 95%. + +Religion + +Azerbaijan is considered the most secular Muslim-majority country. Around 97% of the population are Muslims. Around 55–65% of Muslims are estimated to be Shia, while 35–45% of Muslims are Sunnis. Other faiths are practised by the country's various ethnic groups. Under article 48 of its Constitution, Azerbaijan is a secular state and ensures religious freedom. In a 2006–2008 Gallup poll, only 21% of respondents from Azerbaijan stated that religion is an important part of their daily lives. + +Of the nation's religious minorities, the estimated 280,000 Christians (3.1%) are mostly Russian and Georgian Orthodox and Armenian Apostolic (almost all Armenians live in the break-away region of Nagorno-Karabakh). In 2003, there were 250 Roman Catholics. Other Christian denominations as of 2002 include Lutherans, Baptists and Molokans. There is also a small Protestant community. Azerbaijan also has an ancient Jewish population with a 2,000-year history; Jewish organizations estimate that 12,000 Jews remain in Azerbaijan, which is home to the only Jewish-majority town outside of Israel and the United States. Azerbaijan also is home to members of the Baháʼí, Hare Krishna and Jehovah's Witnesses communities, as well as adherents of the other religious communities. Some religious communities have been unofficially restricted from religious freedom. A U.S. State Department report on the matter mentions detention of members of certain Muslim and Christian groups, and many groups have difficulty registering with the agency who regulates religion, The State Committee on Religious Associations of the Republic of Azerbaijan (SCWRA). + +Education + +A relatively high percentage of Azerbaijanis have obtained some form of higher education, most notably in scientific and technical subjects. In the Soviet era, literacy and average education levels rose dramatically from their very low starting point, despite two changes in the standard alphabet, from Perso-Arabic script to Latin in the 1920s and from Roman to Cyrillic in the 1930s. According to Soviet data, 100 percent of males and females (ages nine to forty-nine) were literate in 1970. According to the United Nations Development Program Report 2009, the literacy rate in Azerbaijan is 99.5 percent. + +Since independence, one of the first laws that Azerbaijan's Parliament passed to disassociate itself from the Soviet Union was to adopt a modified-Latin alphabet to replace Cyrillic. Other than that the Azerbaijani system has undergone little structural change. Initial alterations have included the reestablishment of religious education (banned during the Soviet period) and curriculum changes that have reemphasized the use of the Azerbaijani language and have eliminated ideological content. In addition to elementary schools, the education institutions include thousands of preschools, general secondary schools, and vocational schools, including specialized secondary schools and technical schools. Education through the ninth grade is compulsory. + +Culture + +The culture of Azerbaijan has developed as a result of many influences; that is why Azerbaijanis are, in many ways, bi-cultural. Today, national traditions are well preserved in the country despite Western influences, including globalized consumer culture. Some of the main elements of the Azerbaijani culture are: music, literature, folk dances and art, cuisine, architecture, cinematography and Novruz Bayram. The latter is derived from the traditional celebration of the New Year in the ancient Iranian religion of Zoroastrianism. Novruz is a family holiday. + +The profile of Azerbaijan's population consists, as stated above, of Azerbaijanis, as well as other nationalities or ethnic groups, compactly living in various areas of the country. Azerbaijani national and traditional dresses are the Chokha and Papakhi. There are radio broadcasts in Russian, Georgian, Kurdish, Lezgian and Talysh languages, which are financed from the state budget. Some local radio stations in Balakan and Khachmaz organize broadcasts in Avar and Tat. In Baku several newspapers are published in Russian, Kurdish (Dengi Kurd), Lezgian (Samur) and Talysh languages. Jewish society "Sokhnut" publishes the newspaper Aziz. + +Music and folk dances + +Music of Azerbaijan builds on folk traditions that reach back nearly a thousand years. For centuries Azerbaijani music has evolved under the badge of monody, producing rhythmically diverse melodies. Azerbaijani music has a branchy mode system, where chromatization of major and minor scales is of great importance. Among national musical instruments there are 14 string instruments, eight percussion instruments and six wind instruments. According to The Grove Dictionary of Music and Musicians, "in terms of ethnicity, culture and religion the Azerbaijani are musically much closer to Iran than Turkey." + +Mugham, meykhana and ashiq art are among the many musical traditions of Azerbaijan. Mugham is usually a suite with poetry and instrumental interludes. When performing mugham, the singers have to transform their emotions into singing and music. In contrast to the mugham traditions of Central Asian countries, Azerbaijani mugham is more free-form and less rigid; it is often compared to the improvised field of jazz. UNESCO proclaimed the Azerbaijani mugham tradition a Masterpiece of the Oral and Intangible Heritage of Humanity on 7 November 2003. Meykhana is a kind of traditional Azerbaijani distinctive folk unaccompanied song, usually performed by several people improvising on a particular subject. + +Ashiq combines poetry, storytelling, dance, and vocal and instrumental music into a traditional performance art that stands as a symbol of Azerbaijani culture. It is a mystic troubadour or traveling bard who sings and plays the saz. This tradition has its origin in the Shamanistic beliefs of ancient Turkic peoples. Ashiqs' songs are semi-improvised around common bases. Azerbaijan's ashiq art was included in the list of Intangible Cultural Heritage by the UNESCO on 30 September 2009. + +Since the mid-1960s, Western-influenced Azerbaijani pop music, in its various forms, that has been growing in popularity in Azerbaijan, while genres such as rock and hip hop are widely produced and enjoyed. Azerbaijani pop and Azerbaijani folk music arose with the international popularity of performers like Alim Qasimov, Rashid Behbudov, Vagif Mustafazadeh, Muslim Magomayev, Shovkat Alakbarova and Rubaba Muradova. Azerbaijan is an enthusiastic participant in the Eurovision Song Contest. Azerbaijan made its debut appearance at the 2008 Eurovision Song Contest. The country's entry gained third place in 2009 and fifth the following year. Ell and Nikki won the first place at the Eurovision Song Contest 2011 with the song "Running Scared", entitling Azerbaijan to host the contest in 2012, in Baku. They have qualified for every Grand Final up until the 2018 edition of the contest, entering with X My Heart by singer Aisel. + +There are dozens of Azerbaijani folk dances. They are performed at formal celebrations and the dancers wear national clothes like the Chokha, which is well-preserved within the national dances. Most dances have a very fast rhythm. + +Literature + +Among the medieval authors born within the territorial limits of modern Azerbaijani Republic was Persian poet and philosopher Nizami, called Ganjavi after his place of birth, Ganja, who was the author of the Khamsa ("The Quintuplet"), composed of five romantic poems, including "The Treasure of Mysteries", "Khosrow and Shīrīn", and "Leyli and Mejnūn". + +The earliest known figure in written Azerbaijani literature was Izzeddin Hasanoghlu, who composed a divan consisting of Persian and Azerbaijani ghazals. In Persian ghazals he used his pen-name, while his Azerbaijani ghazals were composed under his own name of Hasanoghlu. + +Classical literature in Azerbaijani was formed in the 14th century based on the various Early Middle Ages dialects of Tabriz and Shirvan. Among the poets of this period were Gazi Burhanaddin, Haqiqi (pen-name of Jahan Shah Qara Qoyunlu), and Habibi. The end of the 14th century was also the period of starting literary activity of Imadaddin Nasimi, one of the greatest Azerbaijani Hurufi mystical poets of the late 14th and early 15th centuries and one of the most prominent early divan masters in Turkic literary history, who also composed poetry in Persian and Arabic. The divan and ghazal styles were further developed by poets Qasem-e Anvar, Fuzuli and Khatai (pen-name of Safavid Shah Ismail I). + +The Book of Dede Korkut consists of two manuscripts copied in the 16th century, and was not written earlier than the 15th century. It is a collection of 12 stories reflecting the oral tradition of Oghuz nomads. The 16th-century poet, Muhammed Fuzuli produced his timeless philosophical and lyrical Qazals in Arabic, Persian, and Azerbaijani. Benefiting immensely from the fine literary traditions of his environment, and building upon the legacy of his predecessors, Fuzuli was destined to become the leading literary figure of his society. His major works include The Divan of Ghazals and The Qasidas. In the same century, Azerbaijani literature further flourished with the development of Ashik () poetic genre of bards. During the same period, under the pen-name of Khatāī ( for sinner) Shah Ismail I wrote about 1400 verses in Azerbaijani, which were later published as his Divan. A unique literary style known as qoshma ( for improvisation) was introduced in this period, and developed by Shah Ismail and later by his son and successor, Shah Tahmasp I. + +In the span of the 17th and 18th centuries, Fuzuli's unique genres as well Ashik poetry were taken up by prominent poets and writers such as Qovsi of Tabriz, Shah Abbas Sani, , Nishat, Molla Vali Vidadi, Molla Panah Vagif, Amani, Zafar and others. Along with Turks, Turkmens and Uzbeks, Azerbaijanis also celebrate the Epic of Koroglu (from for blind man's son), a legendary folk hero. Several documented versions of Koroglu epic remain at the Institute for Manuscripts of the National Academy of Sciences of Azerbaijan. + +Modern Azerbaijani literature in Azerbaijan is based on the Shirvani dialect mainly, while in Iran it is based on the Tabrizi one. The first newspaper in Azerbaijani, Akinchi was published in 1875. In the mid-19th century, it was taught in the schools of Baku, Ganja, Shaki, Tbilisi, and Yerevan. Since 1845, it was also taught in the University of Saint Petersburg in Russia. + +Folk art + +Azerbaijanis have a rich and distinctive culture, a major part of which is decorative and applied art. This art form is represented by a wide range of handicrafts, such as chasing, jeweling, engraving in metal, carving in wood, stone, bone, carpet-making, lasing, pattern weaving and printing, and knitting and embroidery. Each of these types of decorative art, evidence of the endowments of the Azerbaijan nation, is very much in favor here. Many interesting facts pertaining to the development of arts and crafts in Azerbaijan were reported by numerous merchants, travelers, and diplomats who had visited these places at different times. + +The Azerbaijani carpet is a traditional handmade textile of various sizes, with a dense texture and a pile or pile-less surface, whose patterns are characteristic of Azerbaijan's many carpet-making regions. In November 2010 the Azerbaijani carpet was proclaimed a Masterpiece of Intangible Heritage by UNESCO. + +Azerbaijan has been since ancient times known as a center of a large variety of crafts. The archeological dig on the territory of Azerbaijan testifies to the well-developed agriculture, stock raising, metalworking, pottery, ceramics, and carpet-weaving that date as far back as to the 2nd millennium BC. Archeological sites in Dashbulaq, Hasansu, Zayamchai, and Tovuzchai uncovered from the BTC pipeline have revealed early Iron Age artifacts. + +Azerbaijani carpets can be categorized under several large groups and a multitude of subgroups. Scientific research of the Azerbaijani carpet is connected with the name of Latif Karimov, a prominent scientist and artist. It was his classification that related the four large groups of carpets with the four geographical zones of Azerbaijan, Guba-Shirvan, Ganja-Kazakh, Karabakh and Tabriz. + +Cuisine + +The traditional cuisine is famous for an abundance of vegetables and greens used seasonally in the dishes. Fresh herbs, including mint, cilantro (coriander), dill, basil, parsley, tarragon, leeks, chives, thyme, marjoram, green onion, and watercress, are very popular and often accompany main dishes on the table. Climatic diversity and fertility of the land are reflected in the national dishes, which are based on fish from the Caspian Sea, local meat (mainly mutton and beef), and an abundance of seasonal vegetables and greens. Saffron-rice plov is the flagship food in Azerbaijan and black tea is the national beverage. Azerbaijanis often use traditional armudu (pear-shaped) glass as they have very strong tea culture. Popular traditional dishes include bozbash (lamb soup that exists in several regional varieties with the addition of different vegetables), qutab (fried turnover with a filling of greens or minced meat) and dushbara (sort of dumplings of dough filled with ground meat and flavor). + +Architecture + +Azerbaijani architecture typically combines elements of East and West. Azerbaijani architecture has heavy influences from Persian architecture. Many ancient architectural treasures such as the Maiden Tower and Palace of the Shirvanshahs in the Walled City of Baku survive in modern Azerbaijan. Entries submitted on the UNESCO World Heritage tentative list include the Ateshgah of Baku, Momine Khatun Mausoleum, Hirkan National Park, Binagadi asphalt lake, Lökbatan Mud Volcano, Shusha State Historical and Architectural Reserve, Baku Stage Mountain, Caspian Shore Defensive Constructions, Ordubad National Reserve and the Palace of Shaki Khans. + +Among other architectural treasures are Quadrangular Castle in Mardakan, Parigala in Yukhary Chardaglar, a number of bridges spanning the Aras River, and several mausoleums. In the 19th and early 20th centuries, little monumental architecture was created, but distinctive residences were built in Baku and elsewhere. Among the most recent architectural monuments, the Baku subways are noted for their lavish decor. + +The task for modern Azerbaijani architecture is diverse application of modern aesthetics, the search for an architect's own artistic style and inclusion of the existing historico-cultural environment. Major projects such as Heydar Aliyev Cultural Center, Flame Towers, Baku Crystal Hall, Baku White City and SOCAR Tower have transformed the country's skyline and promotes its contemporary identity. + +Visual art + +The Gamigaya Petroglyphs, which date back to the 1st to 4th millennium BC, are located in Azerbaijan's Ordubad District. They consist of some 1500 dislodged and carved rock paintings with images of deer, goats, bulls, dogs, snakes, birds, fantastic beings, and people, carriages, and various symbols were found on basalt rocks. Norwegian ethnographer and adventurer Thor Heyerdahl was convinced that people from the area went to Scandinavia in about 100 AD, took their boat building skills with them, and transmuted them into the Viking boats in Northern Europe. + +Over the centuries, Azerbaijani art has gone through many stylistic changes. Azerbaijani painting is traditionally characterized by a warmth of colour and light, as exemplified in the works of Azim Azimzade and Bahruz Kangarli, and a preoccupation with religious figures and cultural motifs. Azerbaijani painting enjoyed preeminence in Caucasus for hundreds of years, from the Romanesque and Ottoman periods, and through the Soviet and Baroque periods, the latter two of which saw fruition in Azerbaijan. Other notable artists who fall within these periods include Sattar Bahlulzade, Togrul Narimanbekov, Tahir Salahov, Alakbar Rezaguliyev, Mirza Gadim Iravani, Mikayil Abdullayev and Boyukagha Mirzazade. + +Cinema + +The film industry in Azerbaijan dates back to 1898. Azerbaijan was among the first countries involved in cinematography, with the apparatus first showing up in Baku. In 1919, during the Azerbaijan Democratic Republic, a documentary The Celebration of the Anniversary of Azerbaijani Independence was filmed on the first anniversary of Azerbaijan's independence from Russia, 27 May, and premiered in June 1919 at several theatres in Baku. After the Soviet power was established in 1920, Nariman Narimanov, Chairman of the Revolutionary Committee of Azerbaijan, signed a decree nationalizing Azerbaijan's cinema. This also influenced the creation of Azerbaijani animation. + +In 1991, after Azerbaijan gained its independence from the Soviet Union, the first Baku International Film Festival East-West was held in Baku. In December 2000, the former President of Azerbaijan, Heydar Aliyev, signed a decree proclaiming 2 August to be the professional holiday of filmmakers of Azerbaijan. Today Azerbaijani filmmakers are again dealing with issues similar to those faced by cinematographers prior to the establishment of the Soviet Union in 1920. Once again, both choices of content and sponsorship of films are largely left up to the initiative of the filmmaker. + +Television + +There are three state-owned television channels: AzTV, Idman TV and Medeniyyet TV. There is one public channel and 6 private channels: İctimai Television, Space TV, Lider TV, Azad Azerbaijan TV, , and ARB. + +Human rights + +The Constitution of Azerbaijan claims to guarantee freedom of speech, but this is denied in practice. After several years of decline in press and media freedom, in 2014, the media environment in Azerbaijan deteriorated rapidly under a governmental campaign to silence any opposition and criticism, even while the country led the Committee of Ministers of the Council of Europe (May–November 2014). Spurious legal charges and impunity in violence against journalists have remained the norm. All foreign broadcasts are banned in the country. + +According to the 2013 Freedom House Freedom of the Press report, Azerbaijan's press freedom status is "not free", and Azerbaijan ranks 177th out of 196 countries. + +Christianity is officially recognized. All religious communities are required to register to be allowed to meet, under the risk of imprisonment. This registration is often denied. "Racial discrimination contributes to the country's lack of religious freedom, since many of the Christians are ethnic Armenian or Russian, rather than Azeri Muslim". + +Radio Free Europe/Radio Liberty and Voice of America are banned in Azerbaijan. Discrimination against LGBT people in Azerbaijan is widespread. + +During the last few years, three journalists were killed and several prosecuted in trials described as unfair by international human rights organizations. Azerbaijan had the biggest number of journalists imprisoned in Europe in 2015, according to the Committee to Protect Journalists, and is the 5th most censored country in the world, ahead of Iran and China. Some critical journalists have been arrested for their coverage of the COVID-19 pandemic in Azerbaijan. + +A report by an Amnesty International researcher in October 2015 points to "...the severe deterioration of human rights in Azerbaijan over the past few years. Sadly Azerbaijan has been allowed to get away with unprecedented levels of repression and in the process almost wipe out its civil society." Amnesty's 2015/16 annual report on the country stated "... persecution of political dissent continued. Human rights organizations remained unable to resume their work. At least 18 prisoners of conscience remained in detention at the end of the year. Reprisals against independent journalists and activists persisted both in the country and abroad, while their family members also faced harassment and arrests. International human rights monitors were barred and expelled from the country. Reports of torture and other ill-treatment persisted." + +The Guardian reported in April 2017 that "Azerbaijan's ruling elite operated a secret $2.9bn (£2.2bn) scheme to pay prominent Europeans, buy luxury goods and launder money through a network of opaque British companies .... Leaked data shows that the Azerbaijani leadership, accused of serial human rights abuses, systemic corruption and rigging elections, made more than 16,000 covert payments from 2012 to 2014. Some of this money went to politicians and journalists, as part of an international lobbying operation to deflect criticism of Azerbaijan's president, Ilham Aliyev, and to promote a positive image of his oil-rich country." There was no suggestion that all recipients were aware of the source of the money as it arrived via a disguised route. + +Sport + +Freestyle wrestling has been traditionally regarded as Azerbaijan's national sport, in which Azerbaijan won up to fourteen medals, including four golds since joining the International Olympic Committee. Currently, the most popular sports include football and wrestling. + +Football is the most popular sport in Azerbaijan, and the Association of Football Federations of Azerbaijan with 9,122 registered players, is the largest sporting association in the country. The national football team of Azerbaijan demonstrates relatively low performance in the international arena compared to the nation football clubs. The most successful Azerbaijani football clubs are Neftçi, Qarabağ, and Gabala. In 2012, Neftchi Baku became the first Azerbaijani team to advance to the group stage of a European competition, beating APOEL of Cyprus 4–2 on aggregate in the play-off round of the 2012–13 UEFA Europa League. In 2014, Qarabağ became the second Azerbaijani club advancing to the group stage of UEFA Europa League. In 2017, after beating Copenhagen 2–2 (a) in the play-off round of the UEFA Champions League, Qarabağ became the first Azerbaijani club to reach the Group stage. Futsal is another popular sport in Azerbaijan. The Azerbaijan national futsal team reached fourth place in the 2010 UEFA Futsal Championship, while domestic club Araz Naxçivan clinched bronze medals at the 2009–10 UEFA Futsal Cup and 2013–14 UEFA Futsal Cup. Azerbaijan was the main sponsor of Spanish football club Atlético de Madrid during seasons 2013/2014 and 2014/2015, a partnership that the club described should 'promote the image of Azerbaijan in the world'. + +Azerbaijan is one of the traditional powerhouses of world chess, having hosted many international chess tournaments and competitions and became European Team Chess Championship winners in 2009, 2013 and 2017. Notable chess players from the country's chess schools that have made a great impact on the game include Teimour Radjabov, Shahriyar Mammadyarov, Vladimir Makogonov, Vugar Gashimov and former World Chess Champion Garry Kasparov. , country's home of Shamkir Chess a category 22 event and one of the highest rated tournaments of all time. Backgammon also plays a major role in Azerbaijani culture. The game is very popular in Azerbaijan and is widely played among the local public. There are also different variations of backgammon developed and analyzed by Azerbaijani experts. + +Azerbaijan Women's Volleyball Super League is one of the strongest women leagues in the world. Its women's national team came fourth at the 2005 European Championship. Over the last years, clubs like Rabita Baku and Azerrail Baku achieved great success at European cups. Azerbaijani volleyball players include likes of Valeriya Korotenko, Oksana Parkhomenko, Inessa Korkmaz, Natalya Mammadova, and Alla Hasanova. + +Other Azerbaijani athletes are Namig Abdullayev, Toghrul Asgarov, Rovshan Bayramov, Sharif Sharifov, Mariya Stadnik and Farid Mansurov in wrestling, Nazim Huseynov, Elnur Mammadli, Elkhan Mammadov and Rustam Orujov in judo, Rafael Aghayev in karate, Magomedrasul Majidov and Aghasi Mammadov in boxing, Nizami Pashayev in Olympic weightlifting, Azad Asgarov in pankration, Eduard Mammadov in kickboxing, and K-1 fighter Zabit Samedov. + +Azerbaijan has a Formula One race-track, made in June 2012, and the country hosted its first Formula One Grand Prix on 19 June 2016 and the Azerbaijan Grand Prix in 2017, 2018, 2019, 2021 and 2022. Other annual sporting events held in the country are the Baku Cup tennis tournament and the Tour d'Azerbaïdjan cycling race. + +Azerbaijan hosted several major sport competitions since the late 2000s, including the 2013 F1 Powerboat World Championship, 2012 FIFA U-17 Women's World Cup, 2011 AIBA World Boxing Championships, 2010 European Wrestling Championships, 2009 Rhythmic Gymnastics European Championships, 2014 European Taekwondo Championships, 2014 Rhythmic Gymnastics European Championships, and 2016 World Chess Olympiad. On 8 December 2012, Baku was selected to host the 2015 European Games, the first to be held in the competition's history. Baku also hosted the fourth Islamic Solidarity Games in 2017 and the 2019 European Youth Summer Olympic Festival, and it is also one of the hosts of UEFA Euro 2020, which because of Covid-19 is being held in 2021. + +See also + + Outline of Azerbaijan + Index of Azerbaijan-related articles + List of World Heritage Sites in Azerbaijan + The Defense & Foreign Affairs Handbook on Azerbaijan (2006) + List of startups of Azerbaijan + +Notes + +References + +Further reading + Altstadt, Audrey.

Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. + +Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the twentieth century, professional astronomy has become an activity clearly distinguished from amateur astronomy and associated activities. + +Amateur astronomers typically view the sky at night, when most celestial objects and astronomical events are visible, but others observe during the daytime by viewing the Sun and solar eclipses. Some just look at the sky using nothing more than their eyes or binoculars, but more dedicated amateurs often use portable telescopes or telescopes situated in their private or club observatories. Amateurs can also join as members of amateur astronomical societies, which can advise, educate or guide them towards ways of finding and observing celestial objects. They can also promote the science of astronomy among the general public. + +Objectives + +Collectively, amateur astronomers observe a variety of celestial objects and phenomena. Common targets of amateur astronomers include the Sun, the Moon, planets, stars, comets, meteor showers, and a variety of deep sky objects such as star clusters, galaxies, and nebulae. Many amateurs like to specialise in observing particular objects, types of objects, or types of events which interest them. One branch of amateur astronomy, amateur astrophotography, involves the taking of photos of the night sky. Astrophotography has become more popular with the introduction of far easier to use equipment including, digital cameras, DSLR cameras and relatively sophisticated purpose built high quality CCD cameras. + +Most amateur astronomers work at visible wavelengths, but a small minority experiment with wavelengths outside the visible spectrum. An early pioneer of radio astronomy was Grote Reber, an amateur astronomer who constructed the first purpose built radio telescope in the late 1930s to follow up on the discovery of radio wavelength emissions from space by Karl Jansky. Non-visual amateur astronomy includes the use of infrared filters on conventional telescopes, and also the use of radio telescopes. Some amateur astronomers use home-made radio telescopes, while others use radio telescopes that were originally built for astronomical research but have since been made available for use by amateurs. The One-Mile Telescope is one such example. + +Common tools + +Amateur astronomers use a range of instruments to study the sky, depending on a combination of their interests and resources. Methods include simply looking at the night sky with the naked eye, using binoculars, and using a variety of optical telescopes of varying power and quality, as well as additional sophisticated equipment, such as cameras, to study light from the sky in both the visual and non-visual parts of the spectrum. To further improve studying the visual and non-visual part of the spectrum, amateur astronomers go to rural areas to get away from light pollution. Commercial telescopes are available, new and used, but it is also common for amateur astronomers to build (or commission the building of) their own custom telescopes. Some people even focus on amateur telescope making as their primary interest within the hobby of amateur astronomy. + +Although specialized and experienced amateur astronomers tend to acquire more specialized and more powerful equipment over time, relatively simple equipment is often preferred for certain tasks. Binoculars, for instance, although generally of lower power than the majority of telescopes, also tend to provide a wider field of view, which is preferable for looking at some objects in the night sky. Recent models of iPhones have introduced a “night mode” option when taking pictures as well, that allows you to increase exposure, which is a period of time the picture is being taken for. This optimizes focus on light in the frame which is why it is used primarily at night. + +Amateur astronomers also use star charts that, depending on experience and intentions, may range from simple planispheres through to detailed charts of very specific areas of the night sky. A range of astronomy software is available and used by amateur astronomers, including software that generates maps of the sky, software to assist with astrophotography, observation scheduling software, and software to perform various calculations pertaining to astronomical phenomena. + +Amateur astronomers often like to keep records of their observations, which usually takes the form of an observing log. Observing logs typically record details about which objects were observed and when, as well as describing the details that were seen. Sketching is sometimes used within logs, and photographic records of observations have also been used in recent times. The information gathered is used to help studies and interactions between amateur astronomers in yearly gatherings. Although not professional information or credible, it is a way for the hobby lovers to share their new sightings and experiences. + +The popularity of imaging among amateurs has led to large numbers of web sites being written by individuals about their images and equipment. Much of the social interaction of amateur astronomy occurs on mailing lists or discussion groups. Discussion group servers host numerous astronomy lists. A great deal of the commerce of amateur astronomy, the buying and selling of equipment, occurs online. Many amateurs use online tools to plan their nightly observing sessions, using tools such as the Clear Sky Chart. + +Common techniques + +While a number of interesting celestial objects are readily identified by the naked eye, sometimes with the aid of a star chart, many others are so faint or inconspicuous that technical means are necessary to locate them. Although many methods are used in amateur astronomy, most are variations of a few specific techniques. + +Star hopping + +Star hopping is a method often used by amateur astronomers with low-tech equipment such as binoculars or a manually driven telescope. It involves the use of maps (or memory) to locate known landmark stars, and "hopping" between them, often with the aid of a finderscope. Because of its simplicity, star hopping is a very common method for finding objects that are close to naked-eye stars. + +More advanced methods of locating objects in the sky include telescope mounts with setting circles, which assist with pointing telescopes to positions in the sky that are known to contain objects of interest, and GOTO telescopes, which are fully automated telescopes that are capable of locating objects on demand (having first been calibrated). + +Mobile apps +The advent of mobile applications for use in smartphones has led to the creation of many dedicated apps. These apps allow any user to easily locate celestial objects of interest by simply pointing the smartphone device in that direction in the sky. These apps make use of the inbuilt hardware in the phone, such as GPS location and gyroscope. Useful information about the pointed object like celestial coordinates, the name of the object, its constellation, etc. are provided for a quick reference. Some paid versions give more information. These apps are gradually getting into regular use during observing, for the alignment process of telescopes. + +Setting circles + +Setting circles are angular measurement scales that can be placed on the two main rotation axes of some telescopes. Since the widespread adoption of digital setting circles, any classical engraved setting circle is now specifically identified as an "analog setting circle" (ASC). By knowing the coordinates of an object (usually given in equatorial coordinates), the telescope user can use the setting circle to align (i.e., point) the telescope in the appropriate direction before looking through its eyepiece. A computerized setting circle is called a "digital setting circle" (DSC). Although digital setting circles can be used to display a telescope's RA and Dec coordinates, they are not simply a digital read-out of what can be seen on the telescope's analog setting circles. As with go-to telescopes, digital setting circle computers (commercial names include Argo Navis, Sky Commander, and NGC Max) contain databases of tens of thousands of celestial objects and projections of planet positions. + +To find a celestial object in a telescope equipped with a DSC computer, one does not need to look up the specific RA and Dec coordinates in a book or other resource, and then adjust the telescope to those numerical readings. Rather, the object is chosen from the electronic database, which causes distance values and arrow markers to appear in the display that indicate the distance and direction to move the telescope. The telescope is moved until the two angular distance values reach zero, indicating that the telescope is properly aligned. When both the RA and Dec axes are thus "zeroed out", the object should be in the eyepiece. Many DSCs, like go-to systems, can also work in conjunction with laptop sky programs. + +Computerized systems provide the further advantage of computing coordinate precession. Traditional printed sources are subtitled by the epoch year, which refers to the positions of celestial objects at a given time to the nearest year (e.g., J2005, J2007). Most such printed sources have been updated for intervals of only about every fifty years (e.g., J1900, J1950, J2000). Computerized sources, on the other hand, are able to calculate the right ascension and declination of the "epoch of date" to the exact instant of observation. + +GoTo telescopes + +GOTO telescopes have become more popular since the 1980s as technology has improved and prices have been reduced. With these computer-driven telescopes, the user typically enters the name of the item of interest and the mechanics of the telescope point the telescope towards that item automatically. They have several notable advantages for amateur astronomers intent on research. For example, GOTO telescopes tend to be faster for locating items of interest than star hopping, allowing more time for studying of the object. GOTO also allows manufacturers to add equatorial tracking to mechanically simpler alt-azimuth telescope mounts, allowing them to produce an overall less expensive product. GOTO telescopes usually have to be calibrated using alignment stars in order to provide accurate tracking and positioning. However, several telescope manufacturers have recently developed telescope systems that are calibrated with the use of built-in GPS, decreasing the time it takes to set up a telescope at the start of an observing session. + +Remote-controlled telescopes +With the development of fast Internet in the last part of the 20th century along with advances in computer controlled telescope mounts and CCD cameras "Remote Telescope" astronomy is now a viable means for amateur astronomers not aligned with major telescope facilities to partake in research and deep sky imaging. This enables anyone to control a telescope a great distance away in a dark location. The observer can image through the telescope using CCD cameras. The digital data collected by the telescope is then transmitted and displayed to the user by means of the Internet. An example of a digital remote telescope operation for public use via the Internet is the Bareket observatory, and there are telescope farms in New Mexico, Australia and Atacama in Chile. + +Imaging techniques + +Amateur astronomers engage in many imaging techniques including film, DSLR, LRGB, and CCD astrophotography. Because CCD imagers are linear, image processing may be used to subtract away the effects of light pollution, which has increased the popularity of astrophotography in urban areas. Narrowband filters may also be used to minimize light pollution. + +Scientific research +Scientific research is most often not the main goal for many amateur astronomers, unlike professional astronomers. Work of scientific merit is possible, however, and many amateurs successfully contribute to the knowledge base of professional astronomers. Astronomy is sometimes promoted as one of the few remaining sciences for which amateurs can still contribute useful data. To recognize this, the Astronomical Society of the Pacific annually gives Amateur Achievement Awards for significant contributions to astronomy by amateurs. + +The majority of scientific contributions by amateur astronomers are in the area of data collection. In particular, this applies where large numbers of amateur astronomers with small telescopes are more effective than the relatively small number of large telescopes that are available to professional astronomers. Several organizations, such as the American Association of Variable Star Observers and the British Astronomical Association, exist to help coordinate these contributions. + +Amateur astronomers often contribute toward activities such as monitoring the changes in brightness of variable stars and supernovae, helping to track asteroids, and observing occultations to determine both the shape of asteroids and the shape of the terrain on the apparent edge of the Moon as seen from Earth. With more advanced equipment, but still cheap in comparison to professional setups, amateur astronomers can measure the light spectrum emitted from astronomical objects, which can yield high-quality scientific data if the measurements are performed with due care. A relatively recent role for amateur astronomers is searching for overlooked phenomena (e.g., Kreutz Sungrazers) in the vast libraries of digital images and other data captured by Earth and space based observatories, much of which is available over the Internet. + +In the past and present, amateur astronomers have played a major role in discovering new comets. Recently however, funding of projects such as the Lincoln Near-Earth Asteroid Research and Near Earth Asteroid Tracking projects has meant that most comets are now discovered by automated systems long before it is possible for amateurs to see them. + +Societies + +There are a large number of amateur astronomical societies around the world, that serve as a meeting point for those interested in amateur astronomy. Members range from active observers with their own equipment to "armchair astronomers" who are simply interested in the topic. Societies range widely in their goals and activities, which may depend on a variety of factors such as geographic spread, local circumstances, size, and membership. For example, a small local society located in dark countryside may focus on practical observing and star parties, whereas a large one based in a major city might have numerous members but be limited by light pollution and thus hold regular indoor meetings with guest speakers instead. Major national or international societies generally publish their own journal or newsletter, and some hold large multi-day meetings akin to a scientific conference or convention. They may also have sections devoted to particular topics, such as lunar observation or amateur telescope making. + +Notable amateur astronomers + + George Alcock, discovered several comets and novae. + Thomas Bopp, shared the discovery of Comet Hale-Bopp in 1995 with unemployed PhD physicist Alan Hale. + Robert Burnham Jr. (1931–1993), author of the Celestial Handbook. + Andrew Ainslie Common (1841–1903), built his own very large reflecting telescopes and demonstrated that photography could record astronomical features invisible to the human eye. + Robert E.

Aikido is now practiced in around 140 countries. It was originally developed by Morihei Ueshiba, as a synthesis of his martial studies, philosophy and religious beliefs. Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attackers from injury. Aikido is often translated as "the way of unifying (with) life energy" or as "the way of harmonious spirit". According to the founder's philosophy, the primary goal in the practice of aikido is to overcome oneself instead of cultivating violence or aggressiveness. Morihei Ueshiba used the phrase to refer to this principle. + +Aikido's fundamental principles include: (entering), , (breathing control), (triangular principle) and (turning) movements that redirect the opponent's attack momentum. Its curriculum comprises various techniques, primarily throws and joint locks. It also includes a weapons system encompassing the , and . + +Aikido derives mainly from the martial art of Daitō-ryū Aiki-jūjutsu, but began to diverge from it in the late 1920s, partly due to Ueshiba's involvement with the Ōmoto-kyō religion. Ueshiba's early students' documents bear the term . + +Ueshiba's senior students have different approaches to aikido, depending partly on when they studied with him. Today, aikido is found all over the world in a number of styles, with broad ranges of interpretation and emphasis. However, they all share techniques formulated by Ueshiba and most have concern for the well-being of the attacker. + +Etymology and basic philosophy + +The word "aikido" is formed of three kanji: +  –  – harmony, unifying +  –  – energy, spirit +  –  – way, path + +The term does not readily appear in the Japanese language outside the scope of budō. This has led to many possible interpretations of the word. + + () is mainly used in compounds to mean 'combine, unite, join together, meet', examples being (combined/united), (composition), (unite/combine/join together), (union/alliance/association), (combine/unify), and (mutual agreement). There is an idea of reciprocity, (to get to know one another), (talk/discussion/negotiation), and (meet by appointment). + + () is often used to describe a feeling or emotive action, as in ('I feel X', as in terms of thinking but with less cognitive reasoning), and (feeling/sensation); it is used to mean energy or force, as in (electricity) and (magnetism); it can also refer to qualities or aspects of people or things, as in (spirit/trait/temperament). The characters aeteological history can be traced back to the much older Chinese character of () that is used extensively in Traditional Chinese medicine and acupunture. + +The term in Aikido is found in many other Japanese martial arts such as, judo and kendo, and in various non-martial arts, such as Japanese calligraphy (), flower arranging () and tea ceremony ( or ). + +Therefore, from a purely literal interpretation, aikido is the "Way of combining forces" or "Way of unifying energy", in which the term refers to the martial arts principle or tactic of blending with an attacker's movements for the purpose of controlling their actions with minimal effort. One applies by understanding the rhythm and intent of the attacker to find the optimal position and timing to apply a counter-technique. + +History + +Aikido was created by (1883–1969), referred to by some aikido practitioners as (Great Teacher). The term aikido was coined in the 20th century. Ueshiba envisioned aikido not only as the synthesis of his martial training, but as an expression of his personal philosophy of universal peace and reconciliation. During Ueshiba's lifetime and continuing today, aikido has evolved from the that Ueshiba studied into a variety of expressions by martial artists throughout the world. + +Initial development + +Ueshiba developed aikido primarily during the late 1920s through the 1930s through the synthesis of the older martial arts that he had studied. The core martial art from which aikido derives is Daitō-ryū Aiki-jūjutsu, which Ueshiba studied directly with Takeda Sōkaku, the reviver of that art. Additionally, Ueshiba is known to have studied Tenjin Shin'yō-ryū with Tozawa Tokusaburō in Tokyo in 1901, Gotōha Yagyū Shingan-ryū under Nakai Masakatsu in Sakai from 1903 to 1908, and judo with (1894–1972) in Tanabe in 1911. + +The art of is the primary technical influence on aikido. Along with empty-handed throwing and joint-locking techniques, Ueshiba incorporated training movements with weapons, such as those for the spear (), short staff (), and possibly the . Aikido also derives much of its technical structure from the art of swordsmanship (). + +Ueshiba moved to Hokkaidō in 1912, and began studying under Takeda Sokaku in 1915; His official association with Daitō-ryū continued until 1937. However, during the latter part of that period, Ueshiba had already begun to distance himself from Takeda and the . At that time Ueshiba referred to his martial art as "Aiki Budō". It is unclear exactly when Ueshiba began using the name "aikido", but it became the official name of the art in 1942 when the Greater Japan Martial Virtue Society () was engaged in a government sponsored reorganization and centralization of Japanese martial arts. + +Religious influences + +After Ueshiba left Hokkaidō in 1919, he met and was profoundly influenced by Onisaburo Deguchi, the spiritual leader of the Ōmoto-kyō religion (a neo-Shinto movement) in Ayabe. One of the primary features of Ōmoto-kyō is its emphasis on the attainment of utopia during one's life. This idea was a great influence on Ueshiba's martial arts philosophy of extending love and compassion especially to those who seek to harm others. Aikido demonstrates this philosophy in its emphasis on mastering martial arts so that one may receive an attack and harmlessly redirect it. In an ideal resolution, not only is the receiver unharmed, but so is the attacker. + +In addition to the effect on his spiritual growth, the connection with Deguchi gave Ueshiba entry to elite political and military circles as a martial artist. As a result of this exposure, he was able to attract not only financial backing but also gifted students. Several of these students would found their own styles of aikido. + +International dissemination +Aikido was first introduced to the rest of the world in 1951 by Minoru Mochizuki with a visit to France, where he demonstrated aikido techniques to judo students. He was followed by Tadashi Abe in 1952, who came as the official Aikikai Hombu representative, remaining in France for seven years. Kenji Tomiki toured with a delegation of various martial arts through 15 continental states of the United States in 1953. Later that year, Koichi Tohei was sent by Aikikai Hombu to Hawaii for a full year, where he set up several dōjō. This trip was followed by several subsequent visits and is considered the formal introduction of aikido to the United States. The United Kingdom followed in 1955; Italy in 1964 by Hiroshi Tada; and Germany in 1965 by Katsuaki Asai. Designated the "Official Delegate for Europe and Africa" by Morihei Ueshiba, Masamichi Noro arrived in France in September 1961. Seiichi Sugano was appointed to introduce aikido to Australia in 1965. Today there are aikido dōjō throughout the world. + +Proliferation of independent organizations + +The largest aikido organization is the Aikikai Foundation, which remains under the control of the Ueshiba family. However, aikido has developed into many styles, most of which were formed by Morihei Ueshiba's major students. + +The earliest independent styles to emerge were Yoseikan Aikido, begun by Minoru Mochizuki in 1931, Yoshinkan Aikido, founded by Gozo Shioda in 1955, and Shodokan Aikido, founded by Kenji Tomiki in 1967. The emergence of these styles pre-dated Ueshiba's death and did not cause any major upheavals when they were formalized. Shodokan Aikido, however, was controversial, since it introduced a unique rule-based competition that some felt was contrary to the spirit of aikido. + +After Ueshiba's death in 1969, two more major styles emerged. Significant controversy arose with the departure of the Aikikai Hombu Dojo's chief instructor Koichi Tohei, in 1974. Tohei left as a result of a disagreement with the son of the founder, Kisshomaru Ueshiba, who at that time headed the Aikikai Foundation. The disagreement was over the proper role of development in regular aikido training. After Tohei left, he formed his own style, called Shin Shin Toitsu Aikido, and the organization that governs it, the Ki Society (). + +A final major style evolved from Ueshiba's retirement in Iwama, Ibaraki and the teaching methodology of long term student Morihiro Saito. It is unofficially referred to as the "Iwama style", and at one point a number of its followers formed a loose network of schools they called Iwama Ryu. Although Iwama style practitioners remained part of the Aikikai until Saito's death in 2002, followers of Saito subsequently split into two groups. One remained with the Aikikai and the other formed the independent Shinshin Aikishuren Kai in 2004 around Saito's son Hitohiro Saito. + +Today, the major styles of aikido are each run by a separate governing organization, have their own in Japan, and are taught throughout the world. + +The study of is an important component of aikido. The term does not specifically refer to either physical or mental training, as it encompasses both. The kanji for was written in its older form as up until the Japanese governmental writing reforms after World War II, and now is more prevalently seen in its modern form of . This form has the removal of the eight directions denoting the pre and post natal energies of (Chinese – ) also known in the Art of Aikido as "Source energy". + +The character for is used in everyday Japanese terms, such as , or . has many meanings, including "ambience", "mind", "mood", or "intention and action", however, in traditional martial arts and medicine it is often referred to in its more general terminology as "life energy". Gozo Shioda's Yoshinkan Aikido, considered one of the "hard styles", largely follows Ueshiba's teachings from before World War II, and surmises that the secret to lies in timing and the application of the whole body's strength to a single point. In later years, Ueshiba's application of in aikido took on a softer, more gentle feel. This concept was known as Takemusu Aiki, and many of his later students teach about from this perspective. Koichi Tohei's Ki Society centers almost exclusively around the study of the empirical (albeit subjective) experience of , with students' proficiency in aikido techniques and development ranked separately. + +Training + +In aikido, as in virtually all Japanese martial arts, there are both physical and mental aspects of training. The physical training in aikido is diverse, covering both general physical fitness and conditioning, as well as specific techniques. Because a substantial portion of any aikido curriculum consists of throws, beginners learn how to safely fall or roll. The specific techniques for attack include both strikes and grabs; the techniques for defense consist of throws and pins. After basic techniques are learned, students study freestyle defense against multiple opponents, and techniques with weapons. + +Fitness +Physical training goals pursued in conjunction with aikido include controlled relaxation, correct movement of joints such as hips and shoulders, flexibility, and endurance, with less emphasis on strength training. In aikido, pushing or extending movements are much more common than pulling or contracting movements. This distinction can be applied to general fitness goals for the aikido practitioner. + +In aikido, specific muscles or muscle groups are not isolated and worked to improve tone, mass, or power. Aikido-related training emphasizes the use of coordinated whole-body movement and balance similar to yoga or pilates. For example, many dōjōs begin each class with , which may include stretching and (break falls). + +Roles of and + +Aikido training is based primarily on two partners practicing pre-arranged forms () rather than freestyle practice. The basic pattern is for the receiver of the technique () to initiate an attack against the person who applies the technique—the , or (depending on aikido style), also referred to as (when applying a throwing technique), who neutralises this attack with an aikido technique. + +Both halves of the technique, that of and that of , are considered essential to aikido training. Both are studying aikido principles of blending and adaptation. learns to blend with and control attacking energy, while learns to become calm and flexible in the disadvantageous, off-balance positions in which places them. This "receiving" of the technique is called . continuously seeks to regain balance and cover vulnerabilities (e.g., an exposed side), while uses position and timing to keep off-balance and vulnerable. In more advanced training, will sometimes apply to regain balance and pin or throw . + + refers to the act of receiving a technique. Good involves attention to the technique, the partner, and the immediate environment—it is considered an active part of the process of learning aikido. The method of falling itself is also important, and is a way for the practitioner to receive an aikido technique safely and minimize risk of injury. + +Initial attacks +Aikido techniques are usually a defense against an attack, so students must learn to deliver various types of attacks to be able to practice aikido with a partner. Although attacks are not studied as thoroughly as in striking-based arts, attacks with intent (such as a strong strike or an immobilizing grab) are needed to study correct and effective application of technique. + +Many of the of aikido resemble cuts from a sword or other grasped object, which indicate its origins in techniques intended for armed combat. Other techniques, which explicitly appear to be punches (), are practiced as thrusts with a knife or sword. Kicks are generally reserved for upper-level variations; reasons cited include that falls from kicks are especially dangerous, and that kicks (high kicks in particular) were uncommon during the types of combat prevalent in feudal Japan. + +Some basic strikes include: + is a vertical knifehand strike to the head. In training, this is usually directed at the forehead or the crown for safety, but more dangerous versions of this attack target the bridge of the nose and the maxillary sinus. + is a diagonal knifehand strike to the side of the head or neck. + is a punch to the torso. Specific targets include the chest, abdomen, and solar plexus, sometimes referred to as , or . + is a punch to the face, sometimes referred to as . + +Beginners in particular often practice techniques from grabs, both because they are safer and because it is easier to feel the energy and the direction of the movement of force of a hold than it is for a strike. Some grabs are historically derived from being held while trying to draw a weapon, whereupon a technique could then be used to free oneself and immobilize or strike the attacker while they are grabbing the defender. The following are examples of some basic grabs: + , when one hand grabs one wrist. + , when both hands grab one wrist; sometimes referred to as + , when both hands grab both wrists; sometimes referred to as . + when one shoulder is grabbed. + , when both shoulders are grabbed. It is sometimes combined with an overhead strike as . + , when the lapel is grabbed; sometimes referred to as . + +Basic techniques + +The following are a sample of the basic or widely practiced throws and pins. Many of these techniques derive from Daitō-ryū Aiki-jūjutsu, but some others were invented by Morihei Ueshiba. The precise terminology for some may vary between organisations and styles; the following are the terms used by the Aikikai Foundation. Note that despite the names of the first five techniques listed, they are not universally taught in numeric order. + , a control technique using one hand on the elbow and one hand near the wrist which leverages to the ground. This grip applies pressure into the ulnar nerve at the wrist. + is a pronating wristlock that torques the arm and applies painful nerve pressure. (There is an adductive wristlock or Z-lock in the version.) + is a rotational wristlock that directs upward-spiraling tension throughout the arm, elbow and shoulder. + is a shoulder control technique similar to , but with both hands gripping the forearm. The knuckles (from the palm side) are applied to the recipient's radial nerve against the periosteum of the forearm bone. + is a technique that is visually similar to , but with an inverted grip of the wrist, medial rotation of the arm and shoulder, and downward pressure on the elbow. Common in knife and other weapon take-aways. + is a throw during which 's hand is folded back past the shoulder, locking the shoulder joint. + is a supinating wristlock-throw that stretches the extensor digitorum. + is a loosely used umbrella term for various types of mechanically unrelated techniques; generally do not use joint locks like other techniques. + , throws in which moves through the space occupied by . The classic form superficially resembles a "clothesline" technique. + , a throw in which, beginning with , moving forward, sweeps one hand low ("earth") and the other high ("heaven"), which unbalances so that he or she easily topples over. + , aikido's version of the hip throw; drops their hips lower than those of , then flips over the resultant fulcrum. + or , a throw that locks the arms against each other (the kanji for "10" is a cross-shape: ). + is a throw in which sweeps 's arm back until it locks the shoulder joint, then uses forward pressure to throw them. + +Implementations + +Aikido makes use of body movement () to blend the movement of with the movement of . For example, an "entering" () technique consists of movements inward towards , while a technique uses a pivoting motion. +Additionally, an technique takes place in front of , whereas an technique takes place to their side; a technique is applied with motion to the front of , and a version is applied with motion towards the rear of , usually by incorporating a turning or pivoting motion. Finally, most techniques can be performed while in a seated posture (). Techniques where both and are standing are called , techniques where both start off in are called , and techniques performed with standing and sitting are called (). + +From these few basic techniques, there are numerous of possible implementations. For example, can be applied to an opponent moving forward with a strike (perhaps with an type of movement to redirect the incoming force), or to an opponent who has already struck and is now moving back to reestablish distance (perhaps an version). Specific aikido are typically referred to with the formula "attack-technique(-modifier)"; , for example, refers to any technique executed when is holding one wrist. This could be further specified as (referring to any forward-moving technique from that grab). + + are strikes (or feints) employed during an aikido technique. Some view as attacks against "vital points" meant to cause damage in and of themselves. For instance, Gozo Shioda described using in a brawl to quickly down a gang's leader. Others consider , especially to the face, to be methods of distraction meant to enable other techniques; a strike, even if it is blocked, can startle the target and break their concentration. Additionally, the target may also become unbalanced while attempting to avoid a strike (by jerking the head back, for example) which may allow for an easier throw. Many sayings about are attributed to Morihei Ueshiba, who considered them an essential element of technique. + +Weapons + +Weapons training in aikido traditionally includes the short staff () (these techniques closely resemble the use of the bayonet, or Jūkendō), the wooden sword (), and the knife (). Some schools incorporate firearm-disarming techniques, where either weapon-taking and/or weapon-retention may be taught. Some schools, such as the Iwama style of Morihiro Saito, usually spend substantial time practicing with both and , under the names of , and , respectively. + +The founder developed many of the empty-handed techniques from traditional sword, spear and bayonet movements. Consequently, the practice of the weapons arts gives insight into the origin of techniques and movements, and reinforces the concepts of distance, timing, foot movement, presence and connectedness with one's training partner(s). + +Multiple attackers and +One feature of aikido is training to defend against multiple attackers, often called , or . Freestyle practice with multiple attackers called is a key part of most curricula and is required for the higher-level ranks. exercises a person's ability to intuitively perform techniques in an unstructured environment. Strategic choice of techniques, based on how they reposition the student relative to other attackers, is important in training. For instance, an technique might be used to neutralise the current attacker while turning to face attackers approaching from behind. + +In Shodokan Aikido, differs in that it is not performed with multiple persons with defined roles of defender and attacker, but between two people, where both participants attack, defend, and counter at will. In this respect it resembles judo . + +Injuries +In applying a technique during training, it is the responsibility of to prevent injury to by employing a speed and force of application that is appropriate with their partner's proficiency in . When injuries (especially to the joints) occur, they are often the result of a misjudging the ability of to receive the throw or pin. + +A study of injuries in the martial arts showed that the type of injuries varied considerably from one art to the other. Soft tissue injuries are one of the most common types of injuries found within aikido, as well as joint strain and stubbed fingers and toes. Several deaths from head-and-neck injuries, caused by aggressive in a hazing context, have been reported. + +Mental training +Aikido training is mental as well as physical, emphasizing the ability to relax the mind and body even under the stress of dangerous situations. This is necessary to enable the practitioner to perform the 'enter-and-blend' movements that underlie aikido techniques, wherein an attack is met with confidence and directness. Morihei Ueshiba once remarked that one "must be willing to receive 99% of an opponent's attack and stare death in the face" in order to execute techniques without hesitation. As a martial art concerned not only with fighting proficiency but with the betterment of daily life, this mental aspect is of key importance to aikido practitioners. + +Uniforms and ranking + +Aikido practitioners (commonly called outside Japan) generally progress by promotion through a series of "grades" (), followed by a series of "degrees" (), pursuant to formal testing procedures. Some aikido organizations use belts to distinguish practitioners' grades, often simply white and black belts to distinguish and grades, although some use various belt colors. Testing requirements vary, so a particular rank in one organization is not comparable or interchangeable with the rank of another. Some dōjōs have an age requirement before students can take the rank exam. + +The uniform worn for practicing aikido () is similar to the training uniform () used in most other modern martial arts; simple trousers and a wraparound jacket, usually white. Both thick ("judo-style"), and thin ("karate-style") cotton tops are used. Aikido-specific tops are available with shorter sleeves which reach to just below the elbow. + +Most aikido systems add a pair of wide pleated black or indigo trousers known as (used also in Naginatajutsu, kendo, and iaido). In many schools, the wearing of is reserved for practitioners with ranks or for instructors, while others allow all practitioners to wear a regardless of rank. + +Aikido styles +Aikido styles vary in their intention as due to its holistic nature. The most common differences noted in aikido, when observed externally, relate to the intensity and realism of training. Stanley Pranin has observed that some criticism may stem from weak attacks from , allowing for a conditioned response from , resulting in underdevelopment of the skills needed for the safe and effective practice of both partners. + +To counteract this, some styles allow students to become less compliant over time, but, in keeping with the core philosophies, this is after having demonstrated proficiency in being able to protect themselves and their training partners. Shodokan Aikido addresses the issue by practicing in a competitive format. Such adaptations are debated between styles, with some maintaining that there is no need to adjust their methods because either the criticisms are unjustified, or that they are not training for self-defense or combat effectiveness, but spiritual, fitness or other reasons. + +Reasons for the difference and diversity of teachings, intention, and forms of aikido can be traced to the shift in training focus after the end of Ueshiba's seclusion in Iwama from 1942 to the mid-1950s, as he increasingly emphasized the spiritual and philosophical aspects of aikido. As a result, strikes to vital points by , entering () and initiation of techniques by , the distinction between (front side) and (back side) techniques, and the use of weapons, were all de-emphasized or eliminated from practice. + +Conversely, some styles of aikido place less importance on the spiritual practices emphasized by Ueshiba. According to Minoru Shibata of Aikido Journal: +O-Sensei's aikido was not a continuation and extension of the old and has a distinct discontinuity with past martial and philosophical concepts. + +In other words, aikido practitioners who focus on aikido's roots in traditional or are said to be diverging from what Ueshiba taught, as some critics urge practitioners: + +[Ueshiba's] transcendence to the spiritual and universal reality were the fundamentals of the paradigm that he demonstrated. + +References + +External links + + AikiWeb Aikido Information site on aikido, with essays, forums, gallery, reviews, columns, wiki and other information. + + +Japanese martial arts +Dō +Articles containing video clips +Art is a diverse range of human activity, and its resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. + +There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures. In the Western tradition, the three classical branches of visual art are painting, sculpture, and architecture. Theatre, dance, and other performing arts, as well as literature, music, film and other media such as interactive media, are included in a broader definition of the arts. Until the 17th century, art referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts. + +The nature of art and related concepts, such as creativity and interpretation, are explored in a branch of philosophy known as aesthetics. The resulting artworks are studied in the professional fields of art criticism and the history of art. + +Overview +In the perspective of the history of art, artistic works have existed for almost as long as humankind: from early prehistoric art to contemporary art; however, some theorists think that the typical concept of "artistic works" does not fit well outside modern Western societies. One early sense of the definition of art is closely related to the older Latin meaning, which roughly translates to "skill" or "craft", as associated with words such as "artisan". English words derived from this meaning include artifact, artificial, artifice, medical arts, and military arts. However, there are many other colloquial uses of the word, all with some relation to its etymology. + +Over time, philosophers like Plato, Aristotle, Socrates and Immanuel Kant, among others, questioned the meaning of art. Several dialogues in Plato tackle questions about art: Socrates says that poetry is inspired by the muses, and is not rational. He speaks approvingly of this, and other forms of divine madness (drunkenness, eroticism, and dreaming) in the Phaedrus (265a–c), and yet in the Republic wants to outlaw Homer's great poetic art, and laughter as well. In Ion, Socrates gives no hint of the disapproval of Homer that he expresses in the Republic. The dialogue Ion suggests that Homer's Iliad functioned in the ancient Greek world as the Bible does today in the modern Christian world: as divinely inspired literary art that can provide moral guidance, if only it can be properly interpreted. + +With regards to the literary art and the musical arts, Aristotle considered epic poetry, tragedy, comedy, Dithyrambic poetry and music to be mimetic or imitative art, each varying in imitation by medium, object, and manner. For example, music imitates with the media of rhythm and harmony, whereas dance imitates with rhythm alone, and poetry with language. The forms also differ in their object of imitation. Comedy, for instance, is a dramatic imitation of men worse than average; whereas tragedy imitates men slightly better than average. Lastly, the forms differ in their manner of imitation—through narrative or character, through change or no change, and through drama or no drama. Aristotle believed that imitation is natural to mankind and constitutes one of mankind's advantages over animals. + +The more recent and specific sense of the word art as an abbreviation for creative art or fine art emerged in the early 17th century. Fine art refers to a skill used to express the artist's creativity, or to engage the audience's aesthetic sensibilities, or to draw the audience towards consideration of more refined or finer works of art. + +Within this latter sense, the word art may refer to several things: (i) a study of a creative skill, (ii) a process of using the creative skill, (iii) a product of the creative skill, or (iv) the audience's experience with the creative skill. The creative arts (art as discipline) are a collection of disciplines which produce artworks (art as objects) that are compelled by a personal drive (art as activity) and convey a message, mood, or symbolism for the perceiver to interpret (art as experience). Art is something that stimulates an individual's thoughts, emotions, beliefs, or ideas through the senses. Works of art can be explicitly made for this purpose or interpreted on the basis of images or objects. For some scholars, such as Kant, the sciences and the arts could be distinguished by taking science as representing the domain of knowledge and the arts as representing the domain of the freedom of artistic expression. + +Often, if the skill is being used in a common or practical way, people will consider it a craft instead of art. Likewise, if the skill is being used in a commercial or industrial way, it may be considered commercial art instead of fine art. On the other hand, crafts and design are sometimes considered applied art. Some art followers have argued that the difference between fine art and applied art has more to do with value judgments made about the art than any clear definitional difference. However, even fine art often has goals beyond pure creativity and self-expression. The purpose of works of art may be to communicate ideas, such as in politically, spiritually, or philosophically motivated art; to create a sense of beauty (see aesthetics); to explore the nature of perception; for pleasure; or to generate strong emotions. The purpose may also be seemingly nonexistent. + +The nature of art has been described by philosopher Richard Wollheim as "one of the most elusive of the traditional problems of human culture". Art has been defined as a vehicle for the expression or communication of emotions and ideas, a means for exploring and appreciating formal elements for their own sake, and as mimesis or representation. Art as mimesis has deep roots in the philosophy of Aristotle. Leo Tolstoy identified art as a use of indirect means to communicate from one person to another. Benedetto Croce and R. G. Collingwood advanced the idealist view that art expresses emotions, and that the work of art therefore essentially exists in the mind of the creator. The theory of art as form has its roots in the philosophy of Kant, and was developed in the early 20th century by Roger Fry and Clive Bell. More recently, thinkers influenced by Martin Heidegger have interpreted art as the means by which a community develops for itself a medium for self-expression and interpretation. George Dickie has offered an institutional theory of art that defines a work of art as any artifact upon which a qualified person or persons acting on behalf of the social institution commonly referred to as "the art world" has conferred "the status of candidate for appreciation". Larry Shiner has described fine art as "not an essence or a fate but something we have made. Art as we have generally understood it is a European invention barely two hundred years old." + +Art may be characterized in terms of mimesis (its representation of reality), narrative (storytelling), expression, communication of emotion, or other qualities. During the Romantic period, art came to be seen as "a special faculty of the human mind to be classified with religion and science". + +History + +A shell engraved by Homo erectus was determined to be between 430,000 and 540,000 years old. A set of eight 130,000 years old white-tailed eagle talons bear cut marks and abrasion that indicate manipulation by neanderthals, possibly for using it as jewelry. A series of tiny, drilled snail shells about 75,000 years old—were discovered in a South African cave. Containers that may have been used to hold paints have been found dating as far back as 100,000 years. + +The oldest piece of art found in Europe is the Riesenhirschknochen der Einhornhöhle, dating back 51,000 years and made by Neanderthals. + +Sculptures, cave paintings, rock paintings and petroglyphs from the Upper Paleolithic dating to roughly 40,000 years ago have been found, but the precise meaning of such art is often disputed because so little is known about the cultures that produced them. + +The first undisputed sculptures and similar art pieces, like the Venus of Hohle Fels, are the numerous objects found at the Caves and Ice Age Art in the Swabian Jura UNESCO World Heritage Site, where the oldest non-stationary works of human art yet discovered were found, in the form of carved animal and humanoid figurines, in addition to the oldest musical instruments unearthed so far, with the artifacts dating between 43.000 and 35.000 BC, so being the first centre of human art. + +Many great traditions in art have a foundation in the art of one of the great ancient civilizations: Ancient Egypt, Mesopotamia, Persia, India, China, Ancient Greece, Rome, as well as Inca, Maya, and Olmec. Each of these centers of early civilization developed a unique and characteristic style in its art. Because of the size and duration of these civilizations, more of their art works have survived and more of their influence has been transmitted to other cultures and later times. Some also have provided the first records of how artists worked. For example, this period of Greek art saw a veneration of the human physical form and the development of equivalent skills to show musculature, poise, beauty, and anatomically correct proportions. + +In Byzantine and Medieval art of the Western Middle Ages, much art focused on the expression of subjects about biblical and religious culture, and used styles that showed the higher glory of a heavenly world, such as the use of gold in the background of paintings, or glass in mosaics or windows, which also presented figures in idealized, patterned (flat) forms. Nevertheless, a classical realist tradition persisted in small Byzantine works, and realism steadily grew in the art of Catholic Europe. + +Renaissance art had a greatly increased emphasis on the realistic depiction of the material world, and the place of humans in it, reflected in the corporeality of the human body, and development of a systematic method of graphical perspective to depict recession in a three-dimensional picture space. + +In the east, Islamic art's rejection of iconography led to emphasis on geometric patterns, calligraphy, and architecture. Further east, religion dominated artistic styles and forms too. India and Tibet saw emphasis on painted sculptures and dance, while religious painting borrowed many conventions from sculpture and tended to bright contrasting colors with emphasis on outlines. China saw the flourishing of many art forms: jade carving, bronzework, pottery (including the stunning terracotta army of Emperor Qin), poetry, calligraphy, music, painting, drama, fiction, etc. Chinese styles vary greatly from era to era and each one is traditionally named after the ruling dynasty. So, for example, Tang dynasty paintings are monochromatic and sparse, emphasizing idealized landscapes, but Ming dynasty paintings are busy and colorful, and focus on telling stories via setting and composition. Japan names its styles after imperial dynasties too, and also saw much interplay between the styles of calligraphy and painting. Woodblock printing became important in Japan after the 17th century. + +The western Age of Enlightenment in the 18th century saw artistic depictions of physical and rational certainties of the clockwork universe, as well as politically revolutionary visions of a post-monarchist world, such as Blake's portrayal of Newton as a divine geometer, or David's propagandistic paintings. This led to Romantic rejections of this in favor of pictures of the emotional side and individuality of humans, exemplified in the novels of Goethe. The late 19th century then saw a host of artistic movements, such as academic art, Symbolism, impressionism and fauvism among others. + +The history of 20th-century art is a narrative of endless possibilities and the search for new standards, each being torn down in succession by the next. Thus the parameters of Impressionism, Expressionism, Fauvism, Cubism, Dadaism, Surrealism, etc. cannot be maintained very much beyond the time of their invention. Increasing global interaction during this time saw an equivalent influence of other cultures into Western art. Thus, Japanese woodblock prints (themselves influenced by Western Renaissance draftsmanship) had an immense influence on impressionism and subsequent development. Later, African sculptures were taken up by Picasso and to some extent by Matisse. Similarly, in the 19th and 20th centuries the West has had huge impacts on Eastern art with originally western ideas like Communism and Post-Modernism exerting a powerful influence. + +Modernism, the idealistic search for truth, gave way in the latter half of the 20th century to a realization of its unattainability. Theodor W. Adorno said in 1970, "It is now taken for granted that nothing which concerns art can be taken for granted any more: neither art itself, nor art in relationship to the whole, nor even the right of art to exist." Relativism was accepted as an unavoidable truth, which led to the period of contemporary art and postmodern criticism, where cultures of the world and of history are seen as changing forms, which can be appreciated and drawn from only with skepticism and irony. Furthermore, the separation of cultures is increasingly blurred and some argue it is now more appropriate to think in terms of a global culture, rather than of regional ones. + +In The Origin of the Work of Art, Martin Heidegger, a German philosopher and seminal thinker, describes the essence of art in terms of the concepts of being and truth. He argues that art is not only a way of expressing the element of truth in a culture, but the means of creating it and providing a springboard from which "that which is" can be revealed. Works of art are not merely representations of the way things are, but actually produce a community's shared understanding. Each time a new artwork is added to any culture, the meaning of what it is to exist is inherently changed. + +Historically, art and artistic skills and ideas have often been spread through trade. An example of this is the Silk Road, where Hellenistic, Iranian, Indian and Chinese influences could mix. Greco Buddhist art is one of the most vivid examples of this interaction. The meeting of different cultures and worldviews also influenced artistic creation. An example of this is the multicultural port metropolis of Trieste at the beginning of the 20th century, where James Joyce met writers from Central Europe and the artistic development of New York City as a cultural melting pot. + +Forms, genres, media, and styles + +The creative arts are often divided into more specific categories, typically along perceptually distinguishable categories such as media, genre, styles, and form. Art form refers to the elements of art that are independent of its interpretation or significance. It covers the methods adopted by the artist and the physical composition of the artwork, primarily non-semantic aspects of the work (i.e., figurae), such as color, contour, dimension, medium, melody, space, texture, and value. Form may also include visual design principles, such as arrangement, balance, contrast, emphasis, harmony, proportion, proximity, and rhythm. + +In general there are three schools of philosophy regarding art, focusing respectively on form, content, and context. Extreme Formalism is the view that all aesthetic properties of art are formal (that is, part of the art form). Philosophers almost universally reject this view and hold that the properties and aesthetics of art extend beyond materials, techniques, and form. Unfortunately, there is little consensus on terminology for these informal properties. Some authors refer to subject matter and content—i.e., denotations and connotations—while others prefer terms like meaning and significance. + +Extreme Intentionalism holds that authorial intent plays a decisive role in the meaning of a work of art, conveying the content or essential main idea, while all other interpretations can be discarded. It defines the subject as the persons or idea represented, and the content as the artist's experience of that subject. For example, the composition of Napoleon I on his Imperial Throne is partly borrowed from the Statue of Zeus at Olympia. As evidenced by the title, the subject is Napoleon, and the content is Ingres's representation of Napoleon as "Emperor-God beyond time and space". Similarly to extreme formalism, philosophers typically reject extreme intentionalism, because art may have multiple ambiguous meanings and authorial intent may be unknowable and thus irrelevant. Its restrictive interpretation is "socially unhealthy, philosophically unreal, and politically unwise". + +Finally, the developing theory of post-structuralism studies art's significance in a cultural context, such as the ideas, emotions, and reactions prompted by a work. The cultural context often reduces to the artist's techniques and intentions, in which case analysis proceeds along lines similar to formalism and intentionalism. However, in other cases historical and material conditions may predominate, such as religious and philosophical convictions, sociopolitical and economic structures, or even climate and geography. Art criticism continues to grow and develop alongside art. + +Skill and craft + +Art can connote a sense of trained ability or mastery of a medium. Art can also refer to the developed and efficient use of a language to convey meaning with immediacy or depth. Art can be defined as an act of expressing feelings, thoughts, and observations. + +There is an understanding that is reached with the material as a result of handling it, which facilitates one's thought processes. +A common view is that the epithet art, particular in its elevated sense, requires a certain level of creative expertise by the artist, whether this be a demonstration of technical ability, an originality in stylistic approach, or a combination of these two. Traditionally skill of execution was viewed as a quality inseparable from art and thus necessary for its success; for Leonardo da Vinci, art, neither more nor less than his other endeavors, was a manifestation of skill. Rembrandt's work, now praised for its ephemeral virtues, was most admired by his contemporaries for its virtuosity. At the turn of the 20th century, the adroit performances of John Singer Sargent were alternately admired and viewed with skepticism for their manual fluency, yet at nearly the same time the artist who would become the era's most recognized and peripatetic iconoclast, Pablo Picasso, was completing a traditional academic training at which he excelled. + +A common contemporary criticism of some modern art occurs along the lines of objecting to the apparent lack of skill or ability required in the production of the artistic object. In conceptual art, Marcel Duchamp's Fountain is among the first examples of pieces wherein the artist used found objects ("ready-made") and exercised no traditionally recognised set of skills. Tracey Emin's My Bed, or Damien Hirst's The Physical Impossibility of Death in the Mind of Someone Living follow this example and also manipulate the mass media. Emin slept (and engaged in other activities) in her bed before placing the result in a gallery as work of art. Hirst came up with the conceptual design for the artwork but has left most of the eventual creation of many works to employed artisans. Hirst's celebrity is founded entirely on his ability to produce shocking concepts. The actual production in many conceptual and contemporary works of art is a matter of assembly of found objects. However, there are many modernist and contemporary artists who continue to excel in the skills of drawing and painting and in creating hands-on works of art. + +Purpose + +Art has had a great number of different functions throughout its history, making its purpose difficult to abstract or quantify to any single concept. This does not imply that the purpose of art is "vague", but that it has had many unique, different reasons for being created. Some of these functions of art are provided in the following outline. The different purposes of art may be grouped according to those that are non-motivated, and those that are motivated (Lévi-Strauss). + +Non-motivated functions +The non-motivated purposes of art are those that are integral to being human, transcend the individual, or do not fulfill a specific external purpose. In this sense, Art, as creativity, is something humans must do by their very nature (i.e., no other species creates art), and is therefore beyond utility. + Basic human instinct for harmony, balance, rhythm. Art at this level is not an action or an object, but an internal appreciation of balance and harmony (beauty), and therefore an aspect of being human beyond utility.Imitation, then, is one instinct of our nature. Next, there is the instinct for 'harmony' and rhythm, meters being manifestly sections of rhythm. Persons, therefore, starting with this natural gift developed by degrees their special aptitudes, till their rude improvisations gave birth to Poetry. – Aristotle + Experience of the mysterious. Art provides a way to experience one's self in relation to the universe. This experience may often come unmotivated, as one appreciates art, music or poetry.The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. – Albert Einstein + Expression of the imagination. Art provides a means to express the imagination in non-grammatic ways that are not tied to the formality of spoken or written language. Unlike words, which come in sequences and each of which have a definite meaning, art provides a range of forms, symbols and ideas with meanings that are malleable.Jupiter's eagle [as an example of art] is not, like logical (aesthetic) attributes of an object, the concept of the sublimity and majesty of creation, but rather something else—something that gives the imagination an incentive to spread its flight over a whole host of kindred representations that provoke more thought than admits of expression in a concept determined by words. They furnish an aesthetic idea, which serves the above rational idea as a substitute for logical presentation, but with the proper function, however, of animating the mind by opening out for it a prospect into a field of kindred representations stretching beyond its ken. – Immanuel Kant + Ritualistic and symbolic functions. In many cultures, art is used in rituals, performances and dances as a decoration or symbol. While these often have no specific utilitarian (motivated) purpose, anthropologists know that they often serve a purpose at the level of meaning within a particular culture. This meaning is not furnished by any one individual, but is often the result of many generations of change, and of a cosmological relationship within the culture.Most scholars who deal with rock paintings or objects recovered from prehistoric contexts that cannot be explained in utilitarian terms and are thus categorized as decorative, ritual or symbolic, are aware of the trap posed by the term 'art'. – Silva Tomaskova + +Motivated functions +Motivated purposes of art refer to intentional, conscious actions on the part of the artists or creator. These may be to bring about political change, to comment on an aspect of society, to convey a specific emotion or mood, to address personal psychology, to illustrate another discipline, to (with commercial arts) sell a product, or used as a form of communication. + Communication. Art, at its simplest, is a form of communication. As most forms of communication have an intent or goal directed toward another individual, this is a motivated purpose. Illustrative arts, such as scientific illustration, are a form of art as communication. Maps are another example. However, the content need not be scientific. Emotions, moods and feelings are also communicated through art.[Art is a set of] artefacts or images with symbolic meanings as a means of communication. – Steve Mithen + Art as entertainment. Art may seek to bring about a particular emotion or mood, for the purpose of relaxing or entertaining the viewer. This is often the function of the art industries of motion pictures and video games. + The Avant-Garde. Art for political change. One of the defining functions of early 20th-century art has been to use visual images to bring about political change. Art movements that had this goal—Dadaism, Surrealism, Russian constructivism, and Abstract Expressionism, among others—are collectively referred to as the avant-garde arts.By contrast, the realistic attitude, inspired by positivism, from Saint Thomas Aquinas to Anatole France, clearly seems to me to be hostile to any intellectual or moral advancement. I loathe it, for it is made up of mediocrity, hate, and dull conceit. It is this attitude which today gives birth to these ridiculous books, these insulting plays. It constantly feeds on and derives strength from the newspapers and stultifies both science and art by assiduously flattering the lowest of tastes; clarity bordering on stupidity, a dog's life. – André Breton (Surrealism) + Art as a "free zone", removed from the action of the social censure. Unlike the avant-garde movements, which wanted to erase cultural differences in order to produce new universal values, contemporary art has enhanced its tolerance towards cultural differences as well as its critical and liberating functions (social inquiry, activism, subversion, deconstruction, etc.), becoming a more open place for research and experimentation. + Art for social inquiry, subversion or anarchy. While similar to art for political change, subversive or deconstructivist art may seek to question aspects of society without any specific political goal. In this case, the function of art may be used to criticize some aspect of society. Graffiti art and other types of street art are graphics and images that are spray-painted or stencilled on publicly viewable walls, buildings, buses, trains, and bridges, usually without permission. Certain art forms, such as graffiti, may also be illegal when they break laws (in this case vandalism). + Art for social causes. Art can be used to raise awareness for a large variety of causes. A number of art activities were aimed at raising awareness of autism, cancer, human trafficking, and a variety of other topics, such as ocean conservation, human rights in Darfur, murdered and missing Aboriginal women, elder abuse, and pollution. Trashion, using trash to make fashion, practiced by artists such as Marina DeBris is one example of using art to raise awareness about pollution. + Art for psychological and healing purposes. Art is also used by art therapists, psychotherapists and clinical psychologists as art therapy. The Diagnostic Drawing Series, for example, is used to determine the personality and emotional functioning of a patient. The end product is not the principal goal in this case, but rather a process of healing, through creative acts, is sought. The resultant piece of artwork may also offer insight into the troubles experienced by the subject and may suggest suitable approaches to be used in more conventional forms of psychiatric therapy. + Art for propaganda, or commercialism. Art is often used as a form of propaganda, and thus can be used to subtly influence popular conceptions or mood. In a similar way, art that tries to sell a product also influences mood and emotion. In both cases, the purpose of art here is to subtly manipulate the viewer into a particular emotional or psychological response toward a particular idea or object. + Art as a fitness indicator. It has been argued that the ability of the human brain by far exceeds what was needed for survival in the ancestral environment. One evolutionary psychology explanation for this is that the human brain and associated traits (such as artistic ability and creativity) are the human equivalent of the peacock's tail. The purpose of the male peacock's extravagant tail has been argued to be to attract females (see also Fisherian runaway and handicap principle). According to this theory superior execution of art was evolutionarily important because it attracted mates. + +The functions of art described above are not mutually exclusive, as many of them may overlap. For example, art for the purpose of entertainment may also seek to sell a product, i.e. the movie or video game. + +Steps +Art can be divided into any number of steps one can make an argument for. This section divides the creative process into broad three steps, but there is no consensus on an exact number. + +Preparation + +In the first step, the artist envisions the art in their mind. By imagining what their art would look like, the artist begins the process of bringing the art into existence. Preparation of art may involve approaching and researching the subject matter. Artistic inspiration is one of the main drivers of art, and may be considered to stem from instinct, impressions, and feelings. + +Creation + +In the second step, the artist executes the creation of their work. The creation of a piece can be affected by factors such as the artist's mood, surroundings, and mental state. For example, The Black Paintings by Francisco de Goya, created in the elder years of his life, are thought to be so bleak because he was in isolation and because of his experience with war. He painted them directly on the walls of his apartment in Spain, and most likely never discussed them with anyone. The Beatles stated drugs such as LSD and cannabis influenced some of their greatest hits, such as Revolver. Trial and error are considered an integral part of the creation process. + +Appreciation +The last step is art appreciation, which has the sub-topic of critique. In one study, over half of visual arts students agreed that reflection is an essential step of the art process. According to education journals, the reflection of art is considered an essential part of the experience. However an important aspect of art is that others may view and appreciate it as well. While many focus on whether those viewing/listening/etc. believe the art to be good/successful or not, art has profound value beyond its commercial success as a provider of information and health in society. Art enjoyment can bring about a wide spectrum of emotion due to beauty. Some art is meant to be practical, with its analysis studious, meant to stimulate discourse. + +Public access + +Since ancient times, much of the finest art has represented a deliberate display of wealth or power, often achieved by using massive scale and expensive materials. Much art has been commissioned by political rulers or religious establishments, with more modest versions only available to the most wealthy in society. + +Nevertheless, there have been many periods where art of very high quality was available, in terms of ownership, across large parts of society, above all in cheap media such as pottery, which persists in the ground, and perishable media such as textiles and wood. In many different cultures, the ceramics of indigenous peoples of the Americas are found in such a wide range of graves that they were clearly not restricted to a social elite, though other forms of art may have been. Reproductive methods such as moulds made mass-production easier, and were used to bring high-quality Ancient Roman pottery and Greek Tanagra figurines to a very wide market. Cylinder seals were both artistic and practical, and very widely used by what can be loosely called the middle class in the Ancient Near East. Once coins were widely used, these also became an art form that reached the widest range of society. + +Another important innovation came in the 15th century in Europe, when printmaking began with small woodcuts, mostly religious, that were often very small and hand-colored, and affordable even by peasants who glued them to the walls of their homes. Printed books were initially very expensive, but fell steadily in price until by the 19th century even the poorest could afford some with printed illustrations. Popular prints of many different sorts have decorated homes and other places for centuries. + +In 1661, the city of Basel, in Switzerland, opened the first public museum of art in the world, the Kunstmuseum Basel. Today, its collection is distinguished by an impressively wide historic span, from the early 15th century up to the immediate present. Its various areas of emphasis give it international standing as one of the most significant museums of its kind. These encompass: paintings and drawings by artists active in the Upper Rhine region between 1400 and 1600, and on the art of the 19th to 21st centuries. + +Public buildings and monuments, secular and religious, by their nature normally address the whole of society, and visitors as viewers, and display to the general public has long been an important factor in their design. Egyptian temples are typical in that the most largest and most lavish decoration was placed on the parts that could be seen by the general public, rather than the areas seen only by the priests. Many areas of royal palaces, castles and the houses of the social elite were often generally accessible, and large parts of the art collections of such people could often be seen, either by anybody, or by those able to pay a small price, or those wearing the correct clothes, regardless of who they were, as at the Palace of Versailles, where the appropriate extra accessories (silver shoe buckles and a sword) could be hired from shops outside. + +Special arrangements were made to allow the public to see many royal or private collections placed in galleries, as with the Orleans Collection mostly housed in a wing of the Palais Royal in Paris, which could be visited for most of the 18th century. In Italy the art tourism of the Grand Tour became a major industry from the Renaissance onwards, and governments and cities made efforts to make their key works accessible. The British Royal Collection remains distinct, but large donations such as the Old Royal Library were made from it to the British Museum, established in 1753. The Uffizi in Florence opened entirely as a gallery in 1765, though this function had been gradually taking the building over from the original civil servants' offices for a long time before. The building now occupied by the Prado in Madrid was built before the French Revolution for the public display of parts of the royal art collection, and similar royal galleries open to the public existed in Vienna, Munich and other capitals. The opening of the Musée du Louvre during the French Revolution (in 1793) as a public museum for much of the former French royal collection certainly marked an important stage in the development of public access to art, transferring ownership to a republican state, but was a continuation of trends already well established. + +Most modern public museums and art education programs for children in schools can be traced back to this impulse to have art available to everyone. However, museums do not only provide availability to art, but do also influence the way art is being perceived by the audience, as studies found. Thus, the museum itself is not only a blunt stage for the presentation of art, but plays an active and vital role in the overall perception of art in modern society. + +Museums in the United States tend to be gifts from the very rich to the masses. (The Metropolitan Museum of Art in New York City, for example, was created by John Taylor Johnston, a railroad executive whose personal art collection seeded the museum.) But despite all this, at least one of the important functions of art in the 21st century remains as a marker of wealth and social status. + +There have been attempts by artists to create art that can not be bought by the wealthy as a status object. One of the prime original motivators of much of the art of the late 1960s and 1970s was to create art that could not be bought and sold. It is "necessary to present something more than mere objects" said the major post war German artist Joseph Beuys. This time period saw the rise of such things as performance art, video art, and conceptual art. The idea was that if the artwork was a performance that would leave nothing behind, or was an idea, it could not be bought and sold. "Democratic precepts revolving around the idea that a work of art is a commodity impelled the aesthetic innovation which germinated in the mid-1960s and was reaped throughout the 1970s. Artists broadly identified under the heading of Conceptual art ... substituting performance and publishing activities for engagement with both the material and materialistic concerns of painted or sculptural form ... [have] endeavored to undermine the art object qua object." +In the decades since, these ideas have been somewhat lost as the art market has learned to sell limited edition DVDs of video works, invitations to exclusive performance art pieces, and the objects left over from conceptual pieces. Many of these performances create works that are only understood by the elite who have been educated as to why an idea or video or piece of apparent garbage may be considered art. The marker of status becomes understanding the work instead of necessarily owning it, and the artwork remains an upper-class activity. "With the widespread use of DVD recording technology in the early 2000s, artists, and the gallery system that derives its profits from the sale of artworks, gained an important means of controlling the sale of video and computer artworks in limited editions to collectors." + +Controversies + +Art has long been controversial, that is to say disliked by some viewers, for a wide variety of reasons, though most pre-modern controversies are dimly recorded, or completely lost to a modern view. Iconoclasm is the destruction of art that is disliked for a variety of reasons, including religious ones. Aniconism is a general dislike of either all figurative images, or often just religious ones, and has been a thread in many major religions. It has been a crucial factor in the history of Islamic art, where depictions of Muhammad remain especially controversial. Much art has been disliked purely because it depicted or otherwise stood for unpopular rulers, parties or other groups. Artistic conventions have often been conservative and taken very seriously by art critics, though often much less so by a wider public. The iconographic content of art could cause controversy, as with late medieval depictions of the new motif of the Swoon of the Virgin in scenes of the Crucifixion of Jesus. The Last Judgment by Michelangelo was controversial for various reasons, including breaches of decorum through nudity and the Apollo-like pose of Christ. + +The content of much formal art through history was dictated by the patron or commissioner rather than just the artist, but with the advent of Romanticism, and economic changes in the production of art, the artists' vision became the usual determinant of the content of his art, increasing the incidence of controversies, though often reducing their significance. Strong incentives for perceived originality and publicity also encouraged artists to court controversy. Théodore Géricault's Raft of the Medusa (), was in part a political commentary on a recent event. Édouard Manet's Le Déjeuner sur l'Herbe (1863), was considered scandalous not because of the nude woman, but because she is seated next to men fully dressed in the clothing of the time, rather than in robes of the antique world. John Singer Sargent's Madame Pierre Gautreau (Madam X) (1884), caused a controversy over the reddish pink used to color the woman's ear lobe, considered far too suggestive and supposedly ruining the high-society model's reputation. +The gradual abandonment of naturalism and the depiction of realistic representations of the visual appearance of subjects in the 19th and 20th centuries led to a rolling controversy lasting for over a century. + +In the 20th century, Pablo Picasso's Guernica (1937) used arresting cubist techniques and stark monochromatic oils, to depict the harrowing consequences of a contemporary bombing of a small, ancient Basque town. Leon Golub's Interrogation III (1981), depicts a female nude, hooded detainee strapped to a chair, her legs open to reveal her sexual organs, surrounded by two tormentors dressed in everyday clothing. Andres Serrano's Piss Christ (1989) is a photograph of a crucifix, sacred to the Christian religion and representing Christ's sacrifice and final suffering, submerged in a glass of the artist's own urine. The resulting uproar led to comments in the United States Senate about public funding of the arts. + +Theory + +Before Modernism, aesthetics in Western art was greatly concerned with achieving the appropriate balance between different aspects of realism or truth to nature and the ideal; ideas as to what the appropriate balance is have shifted to and fro over the centuries. This concern is largely absent in other traditions of art. The aesthetic theorist John Ruskin, who championed what he saw as the naturalism of J. M. W. Turner, saw art's role as the communication by artifice of an essential truth that could only be found in nature. + +The definition and evaluation of art has become especially problematic since the 20th century. Richard Wollheim distinguishes three approaches to assessing the aesthetic value of art: the Realist, whereby aesthetic quality is an absolute value independent of any human view; the Objectivist, whereby it is also an absolute value, but is dependent on general human experience; and the Relativist position, whereby it is not an absolute value, but depends on, and varies with, the human experience of different humans. + +Arrival of Modernism + +The arrival of Modernism in the late 19th century lead to a radical break in the conception of the function of art, and then again in the late 20th century with the advent of postmodernism. Clement Greenberg's 1960 article "Modernist Painting" defines modern art as "the use of characteristic methods of a discipline to criticize the discipline itself". Greenberg originally applied this idea to the Abstract Expressionist movement and used it as a way to understand and justify flat (non-illusionistic) abstract painting: +Realistic, naturalistic art had dissembled the medium, using art to conceal art; modernism used art to call attention to art. The limitations that constitute the medium of painting—the flat surface, the shape of the support, the properties of the pigment—were treated by the Old Masters as negative factors that could be acknowledged only implicitly or indirectly. Under Modernism these same limitations came to be regarded as positive factors, and were acknowledged openly. After Greenberg, several important art theorists emerged, such as Michael Fried, T. J. Clark, Rosalind Krauss, Linda Nochlin and Griselda Pollock among others. Though only originally intended as a way of understanding a specific set of artists, Greenberg's definition of modern art is important to many of the ideas of art within the various art movements of the 20th century and early 21st century. + +Pop artists like Andy Warhol became both noteworthy and influential through work including and possibly critiquing popular culture, as well as the art world. Artists of the 1980s, 1990s, and 2000s expanded this technique of self-criticism beyond high art to all cultural image-making, including fashion images, comics, billboards and pornography. + +Duchamp once proposed that art is any activity of any kind-everything. However, the way that only certain activities are classified today as art is a social construction. There is evidence that there may be an element of truth to this. In The Invention of Art: A Cultural History, Larry Shiner examines the construction of the modern system of the arts, i.e. fine art. He finds evidence that the older system of the arts before our modern system (fine art) held art to be any skilled human activity; for example, Ancient Greek society did not possess the term art, but techne. Techne can be understood neither as art or craft, the reason being that the distinctions of art and craft are historical products that came later on in human history. Techne included painting, sculpting and music, but also cooking, medicine, horsemanship, geometry, carpentry, prophecy, and farming, etc. + +New Criticism and the "intentional fallacy" +Following Duchamp during the first half of the 20th century, a significant shift to general aesthetic theory took place which attempted to apply aesthetic theory between various forms of art, including the literary arts and the visual arts, to each other. This resulted in the rise of the New Criticism school and debate concerning the intentional fallacy. At issue was the question of whether the aesthetic intentions of the artist in creating the work of art, whatever its specific form, should be associated with the criticism and evaluation of the final product of the work of art, or, if the work of art should be evaluated on its own merits independent of the intentions of the artist. + +In 1946, William K. Wimsatt and Monroe Beardsley published a classic and controversial New Critical essay entitled "The Intentional Fallacy", in which they argued strongly against the relevance of an author's intention, or "intended meaning" in the analysis of a literary work. For Wimsatt and Beardsley, the words on the page were all that mattered; importation of meanings from outside the text was considered irrelevant, and potentially distracting. + +In another essay, "The Affective Fallacy", which served as a kind of sister essay to "The Intentional Fallacy" Wimsatt and Beardsley also discounted the reader's personal/emotional reaction to a literary work as a valid means of analyzing a text. This fallacy would later be repudiated by theorists from the reader-response school of literary theory. Ironically, one of the leading theorists from this school, Stanley Fish, was himself trained by New Critics. Fish criticizes Wimsatt and Beardsley in his 1970 essay "Literature in the Reader". + +As summarized by Berys Gaut and Paisley Livingston in their essay "The Creation of Art": "Structuralist and post-structuralists theorists and critics were sharply critical of many aspects of New Criticism, beginning with the emphasis on aesthetic appreciation and the so-called autonomy of art, but they reiterated the attack on biographical criticisms' assumption that the artist's activities and experience were a privileged critical topic." These authors contend that: "Anti-intentionalists, such as formalists, hold that the intentions involved in the making of art are irrelevant or peripheral to correctly interpreting art. So details of the act of creating a work, though possibly of interest in themselves, have no bearing on the correct interpretation of the work." + +Gaut and Livingston define the intentionalists as distinct from formalists stating that: "Intentionalists, unlike formalists, hold that reference to intentions is essential in fixing the correct interpretation of works." They quote Richard Wollheim as stating that, "The task of criticism is the reconstruction of the creative process, where the creative process must in turn be thought of as something not stopping short of, but terminating on, the work of art itself." + +"Linguistic turn" and its debate +The end of the 20th century fostered an extensive debate known as the linguistic turn controversy, or the "innocent eye debate" in the philosophy of art. This debate discussed the encounter of the work of art as being determined by the relative extent to which the conceptual encounter with the work of art dominates over the perceptual encounter with the work of art. + +Decisive for the linguistic turn debate in art history and the humanities were the works of yet another tradition, namely the structuralism of Ferdinand de Saussure and the ensuing movement of poststructuralism. In 1981, the artist Mark Tansey created a work of art titled The Innocent Eye as a criticism of the prevailing climate of disagreement in the philosophy of art during the closing decades of the 20th century. Influential theorists include Judith Butler, Luce Irigaray, Julia Kristeva, Michel Foucault and Jacques Derrida. The power of language, more specifically of certain rhetorical tropes, in art history and historical discourse was explored by Hayden White. The fact that language is a transparent medium of thought had been stressed by a very different form of philosophy of language which originated in the works of Johann Georg Hamann and Wilhelm von Humboldt. Ernst Gombrich and Nelson Goodman in his book Languages of Art: An Approach to a Theory of Symbols came to hold that the conceptual encounter with the work of art predominated exclusively over the perceptual and visual encounter with the work of art during the 1960s and 1970s. He was challenged on the basis of research done by the Nobel prize winning psychologist Roger Sperry who maintained that the human visual encounter was not limited to concepts represented in language alone (the linguistic turn) and that other forms of psychological representations of the work of art were equally defensible and demonstrable. Sperry's view eventually prevailed by the end of the 20th century with aesthetic philosophers such as Nick Zangwill strongly defending a return to moderate aesthetic formalism among other alternatives. + +Classification disputes + + Disputes as to whether or not to classify something as a work of art are referred to as classificatory disputes about art. Classificatory disputes in the 20th century have included cubist and impressionist paintings, Duchamp's Fountain, the movies, J. S. G. Boggs' superlative imitations of banknotes, conceptual art, and video games. Philosopher David Novitz has argued that disagreement about the definition of art are rarely the heart of the problem. Rather, "the passionate concerns and interests that humans vest in their social life" are "so much a part of all classificatory disputes about art." According to Novitz, classificatory disputes are more often disputes about societal values and where society is trying to go than they are about theory proper. For example, when the Daily Mail criticized Hirst's and Emin's work by arguing "For 1,000 years art has been one of our great civilising forces. Today, pickled sheep and soiled beds threaten to make barbarians of us all" they are not advancing a definition or theory about art, but questioning the value of Hirst's and Emin's work. In 1998, Arthur Danto, suggested a thought experiment showing that "the status of an artifact as work of art results from the ideas a culture applies to it, rather than its inherent physical or perceptible qualities. Cultural interpretation (an art theory of some kind) is therefore constitutive of an object's arthood." + +Anti-art is a label for art that intentionally challenges the established parameters and values of art; it is a term associated with Dadaism and attributed to Marcel Duchamp just before World War I, when he was making art from found objects. One of these, Fountain (1917), an ordinary urinal, has achieved considerable prominence and influence on art. Anti-art is a feature of work by Situationist International, the lo-fi Mail art movement, and the Young British Artists, though it is a form still rejected by the Stuckists, who describe themselves as anti-anti-art. + +Architecture is often included as one of the visual arts; however, like the decorative arts, or advertising, it involves the creation of objects where the practical considerations of use are essential in a way that they usually are not in a painting, for example. + +Value judgment + +Somewhat in relation to the above, the word art is also used to apply judgments of value, as in such expressions as "that meal was a work of art" (the cook is an artist), or "the art of deception" (the highly attained level of skill of the deceiver is praised). It is this use of the word as a measure of high quality and high value that gives the term its flavor of subjectivity. Making judgments of value requires a basis for criticism. At the simplest level, a way to determine whether the impact of the object on the senses meets the criteria to be considered art is whether it is perceived to be attractive or repulsive. Though perception is always colored by experience, and is necessarily subjective, it is commonly understood that what is not somehow aesthetically satisfying cannot be art. However, "good" art is not always or even regularly aesthetically appealing to a majority of viewers. In other words, an artist's prime motivation need not be the pursuit of the aesthetic. Also, art often depicts terrible images made for social, moral, or thought-provoking reasons. For example, Francisco Goya's painting depicting the Spanish shootings of 3 May 1808 is a graphic depiction of a firing squad executing several pleading civilians. Yet at the same time, the horrific imagery demonstrates Goya's keen artistic ability in composition and execution and produces fitting social and political outrage. Thus, the debate continues as to what mode of aesthetic satisfaction, if any, is required to define 'art'. + +The assumption of new values or the rebellion against accepted notions of what is aesthetically superior need not occur concurrently with a complete abandonment of the pursuit of what is aesthetically appealing. Indeed, the reverse is often true, that the revision of what is popularly conceived of as being aesthetically appealing allows for a re-invigoration of aesthetic sensibility, and a new appreciation for the standards of art itself. Countless schools have proposed their own ways to define quality, yet they all seem to agree in at least one point: once their aesthetic choices are accepted, the value of the work of art is determined by its capacity to transcend the limits of its chosen medium to strike some universal chord by the rarity of the skill of the artist or in its accurate reflection in what is termed the zeitgeist. Art is often intended to appeal to and connect with human emotion. It can arouse aesthetic or moral feelings, and can be understood as a way of communicating these feelings. Artists express something so that their audience is aroused to some extent, but they do not have to do so consciously. Art may be considered an exploration of the human condition; that is, what it is to be human. By extension, it has been argued by Emily L. Spratt that the development of artificial intelligence, especially in regard to its uses with images, necessitates a re-evaluation of aesthetic theory in art history today and a reconsideration of the limits of human creativity. + +Art and law +An essential legal issue are art forgeries, plagiarism, replicas and works that are strongly based on other works of art. + +Intellectual property law plays a significant role in the art world.Copyright protection is granted to artists for their original works, providing them with exclusive rights to reproduce, distribute, and display their creations. This safeguard empowers artists to govern the usage of their work and safeguard against unauthorized copying or infringement. + +The trade in works of art or the export from a country may be subject to legal regulations. Internationally there are also extensive efforts to protect the works of art created. The UN, UNESCO and Blue Shield International try to ensure effective protection at the national level and to intervene directly in the event of armed conflicts or disasters. This can particularly affect museums, archives, art collections and excavation sites. This should also secure the economic basis of a country, especially because works of art are often of tourist importance. The founding president of Blue Shield International, Karl von Habsburg, explained an additional connection between the destruction of cultural property and the cause of flight during a mission in Lebanon in April 2019: "Cultural goods are part of the identity of the people who live in a certain place. If you destroy their culture, you also destroy their identity. Many people are uprooted, often no longer have any prospects and as a result flee from their homeland." In order to preserve the diversity of cultural identity, UNESCO protects the living human treasure through the Convention for the Safeguarding of the Intangible Cultural Heritage. + +See also + + Applied arts + Art movement + Artist in residence + Artistic freedom + Cultural tourism + Craftivism + Formal analysis + History of art + List of artistic media + List of art techniques + Mathematics and art + Street art (or "independent public art") + Outline of the visual arts, a guide to the subject of art presented as a tree structured list of its subtopics. + Visual impairment in art + +Notes + +Works cited + +Bibliography + Oscar Wilde, Intentions, 1891 + Katharine Everett Gilbert and Helmut Kuhn, A History of Esthetics.

Regardless, they appear to be close relatives as part of the Artiopoda. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders, and were highly diverse throughout the Cambrian. Agnostidan diversity severely declined during the Cambrian-Ordovician transition, and the last agnostidans went extinct in the Late Ordovician. + +Systematics +The Agnostida are divided into two suborders — Agnostina and Eodiscina — which are then subdivided into a number of families. As a group, agnostids are isopygous, meaning their pygidium is similar in size and shape to their cephalon. Most agnostid species were eyeless. + +The systematic position of the order Agnostida within the class Trilobita remains uncertain, and there has been continuing debate whether they are trilobites or a stem group. The challenge to the status has focused on Agnostina partly due to the juveniles of one genus have been found with legs differing dramatically from those of adult trilobites, suggesting they are not members of the lamellipedian clade, of which trilobites are a part. Instead, the limbs of agnostids closely resemble those of stem group crustaceans, although they lack the proximal endite, which defines that group. The study suggested that they were likely the sister taxon to the crustacean stem lineage, and, as such, part of the clade, Crustaceomorpha. Other researchers have suggested, based on a cladistic analyses of dorsal exoskeletal features, that Eodiscina and Agnostida are closely united, and the Eodiscina descended from the trilobite order Ptychopariida. A 2019 study of adult specimens with preserved soft tissue from the Burgess Shale found that agnostidans shared morphological similarities to trilobites and other related artiopodans like nektaspids, and their placement as stem-crustaceans was unsupported. The study recovered agnostidans as the sister group to other trilobites within the Artiopoda. + +Ecology +Scientists have long debated whether the agnostids lived a pelagic or a benthic lifestyle. Their lack of eyes, a morphology not well-suited for swimming, and their fossils found in association with other benthic trilobites suggest a benthic (bottom-dwelling) mode of life. They are likely to have lived on areas of the ocean floor which received little or no light and fed on detritus which descended from upper layers of the sea to the bottom. Their wide geographic dispersion in the fossil record is uncharacteristic of benthic animals, suggesting a pelagic existence. The thoracic segment appears to form a hinge between the head and pygidium allowing for a bivalved ostracodan-type lifestyle. The orientation of the thoracic appendages appears ill-suited for benthic living. Recent work suggests that some agnostids were benthic predators, engaging in cannibalism and possibly pack-hunting behavior. + +They are sometimes preserved within the voids of other organisms, for instance within empty hyolith conchs, within sponges, worm tubes and under the carapaces of bivalved arthropods, presumably in order to hide from predators or strong storm currents; or maybe whilst scavenging for food. In the case of the tapering worm tubes Selkirkia, trilobites are always found with their heads directed towards the opening of the tube, suggesting that they reversed in; the absence of any moulted carapaces suggests that moulting was not their primary reason for seeking shelter. + +References + +External links + Order Agnostida by Sam Gon III. + The Virtual Fossil Museum – Trilobite Order Agnostida + Agnostida fact sheet by Sam Gon III. + "Earth's Early Cannibals Caught in the Act", by Larry O'Hanlon, news.discovery.com. + + +Trilobite orders +Cambrian trilobites +Ordovician trilobites +Fossil taxa described in 1864 +Cambrian first appearances +Late Ordovician extinctions +Taxa named by John William Salter +Abortion is the termination of a pregnancy by removal or expulsion of an embryo or fetus. An abortion that occurs without intervention is known as a miscarriage or "spontaneous abortion"; these occur in approximately 30% to 40% of all pregnancies. When deliberate steps are taken to end a pregnancy, it is called an induced abortion, or less frequently "induced miscarriage". The unmodified word abortion generally refers to an induced abortion. The reasons why women have abortions are diverse and vary across the world. Reasons include maternal health, an inability to afford a child, domestic violence, lack of support, feeling they are too young, wishing to complete education or advance a career, and not being able or willing to raise a child conceived as a result of rape or incest. + +When done legally in industrialized societies, induced abortion is one of the safest procedures in medicine. In the United States, the risk of maternal mortality is 14 times lower after induced abortion than after childbirth. Unsafe abortions—those performed by people lacking the necessary skills, or in inadequately resourced settings—are responsible for between 5-13% of maternal deaths, especially in the developing world. However, medication abortions that are self-managed are highly effective and safe throughout the first trimester. Public health data shows that making safe abortion legal and accessible reduces maternal deaths. + +Modern methods use medication or surgery for abortions. The drug mifepristone in combination with prostaglandin appears to be as safe and effective as surgery during the first and second trimesters of pregnancy. The most common surgical technique involves dilating the cervix and using a suction device. Birth control, such as the pill or intrauterine devices, can be used immediately following abortion. When performed legally and safely on a woman who desires it, induced abortions do not increase the risk of long-term mental or physical problems. In contrast, unsafe abortions performed by unskilled individuals, with hazardous equipment, or in unsanitary facilities cause between 22,000 and 44,000 deaths and 6.9 million hospital admissions each year. The World Health Organization states that "access to legal, safe and comprehensive abortion care, including post-abortion care, is essential for the attainment of the highest possible level of sexual and reproductive health". Historically, abortions have been attempted using herbal medicines, sharp tools, forceful massage, or other traditional methods. + +Around 73 million abortions are performed each year in the world, with about 45% done unsafely. Abortion rates changed little between 2003 and 2008, before which they decreased for at least two decades as access to family planning and birth control increased. , 37% of the world's women had access to legal abortions without limits as to reason. Countries that permit abortions have different limits on how late in pregnancy abortion is allowed. Abortion rates are similar between countries that restrict abortion and countries that broadly allow it, though this is partly because countries which restrict abortion tend to have higher unintended pregnancy rates. + +Globally, there has been a widespread trend towards greater legal access to abortion since 1973, but there remains debate with regard to moral, religious, ethical, and legal issues. Those who oppose abortion often argue that an embryo or fetus is a person with a right to life, and thus equate it with murder. Those who support its legality often argue that it is a woman's reproductive right. Others favor legal and accessible abortion as a public health measure. Abortion laws and views of the procedure are different around the world. In some countries abortion is legal and women have the right to make the choice about abortion. In some areas, abortion is legal only in specific cases such as rape, fetal defects, poverty, risk to a woman's health, or incest. + +Types + +Induced +Approximately 205 million pregnancies occur each year worldwide. Over a third are unintended and about a fifth end in induced abortion. Most abortions result from unintended pregnancies. In the United Kingdom, 1 to 2% of abortions are done due to genetic problems in the fetus. A pregnancy can be intentionally aborted in several ways. The manner selected often depends upon the gestational age of the embryo or fetus, which increases in size as the pregnancy progresses. + +Specific procedures may also be selected due to legality, regional availability, and doctor or a woman's personal preference. Reasons for procuring induced abortions are typically characterized as either therapeutic or elective. An abortion is medically referred to as a therapeutic abortion when it is performed to save the life of the pregnant woman; to prevent harm to the woman's physical or mental health; to terminate a pregnancy where indications are that the child will have a significantly increased chance of mortality or morbidity; or to selectively reduce the number of fetuses to lessen health risks associated with multiple pregnancy. An abortion is referred to as an elective or voluntary abortion when it is performed at the request of the woman for non-medical reasons. Confusion sometimes arises over the term elective because "elective surgery" generally refers to all scheduled surgery, whether medically necessary or not. + +Spontaneous + +Miscarriage, also known as spontaneous abortion, is the unintentional expulsion of an embryo or fetus before the 24th week of gestation. A pregnancy that ends before 37 weeks of gestation resulting in a live-born infant is a "premature birth" or a "preterm birth". When a fetus dies in utero after viability, or during delivery, it is usually termed "stillborn". Premature births and stillbirths are generally not considered to be miscarriages, although usage of these terms can sometimes overlap. + +Studies of pregnant women in the US and China have shown that between 40% and 60% of embryos do not progress to birth. The vast majority of miscarriages occur before the woman is aware that she is pregnant, and many pregnancies spontaneously abort before medical practitioners can detect an embryo. Between 15% and 30% of known pregnancies end in clinically apparent miscarriage, depending upon the age and health of the pregnant woman. 80% of these spontaneous abortions happen in the first trimester. + +The most common cause of spontaneous abortion during the first trimester is chromosomal abnormalities of the embryo or fetus, accounting for at least 50% of sampled early pregnancy losses. Other causes include vascular disease (such as lupus), diabetes, other hormonal problems, infection, and abnormalities of the uterus. Advancing maternal age and a woman's history of previous spontaneous abortions are the two leading factors associated with a greater risk of spontaneous abortion. A spontaneous abortion can also be caused by accidental trauma; intentional trauma or stress to cause miscarriage is considered induced abortion or feticide. + +Methods + +Medical + +Medical abortions are those induced by abortifacient pharmaceuticals. Medical abortion became an alternative method of abortion with the availability of prostaglandin analogs in the 1970s and the antiprogestogen mifepristone (also known as RU-486) in the 1980s. + +The most common early first trimester medical abortion regimens use mifepristone in combination with misoprostol (or sometimes another prostaglandin analog, gemeprost) up to 10 weeks (70 days) gestational age, methotrexate in combination with a prostaglandin analog up to 7 weeks gestation, or a prostaglandin analog alone. Mifepristone–misoprostol combination regimens work faster and are more effective at later gestational ages than methotrexate–misoprostol combination regimens, and combination regimens are more effective than misoprostol alone, particularly in the second trimester. Medical abortion regimens involving mifepristone followed by misoprostol in the cheek between 24 and 48 hours later are effective when performed before 70 days' gestation. + +In very early abortions, up to 7 weeks gestation, medical abortion using a mifepristone–misoprostol combination regimen is considered to be more effective than surgical abortion (vacuum aspiration), especially when clinical practice does not include detailed inspection of aspirated tissue. Early medical abortion regimens using mifepristone, followed 24–48 hours later by buccal or vaginal misoprostol are 98% effective up to 9 weeks gestational age; from 9 to 10 weeks efficacy decreases modestly to 94%. If medical abortion fails, surgical abortion must be used to complete the procedure. + +Early medical abortions account for the majority of abortions before 9 weeks gestation in Britain, France, Switzerland, United States, and the Nordic countries. + +Medical abortion regimens using mifepristone in combination with a prostaglandin analog are the most common methods used for second trimester abortions in Canada, most of Europe, China and India, in contrast to the United States where 96% of second trimester abortions are performed surgically by dilation and evacuation. + +A 2020 Cochrane Systematic Review concluded that providing women with medications to take home to complete the second stage of the procedure for an early medical abortion results in an effective abortion. Further research is required to determine if self-administered medical abortion is as safe as provider-administered medical abortion, where a health care professional is present to help manage the medical abortion. Safely permitting women to self-administer abortion medication has the potential to improve access to abortion. Other research gaps that were identified include how to best support women who choose to take the medication home for a self-administered abortion. + +Surgical + +Up to 15 weeks' gestation, suction-aspiration or vacuum aspiration are the most common surgical methods of induced abortion. Manual vacuum aspiration (MVA) consists of removing the fetus or embryo, placenta, and membranes by suction using a manual syringe, while electric vacuum aspiration (EVA) uses an electric pump. These techniques can both be used very early in pregnancy. MVA can be used up to 14 weeks but is more often used earlier in the U.S. EVA can be used later. + +MVA, also known as "mini-suction" and "menstrual extraction", or EVA can be used in very early pregnancy when cervical dilation may not be required. Dilation and curettage (D&C) refers to opening the cervix (dilation) and removing tissue (curettage) via suction or sharp instruments. D&C is a standard gynecological procedure performed for a variety of reasons, including examination of the uterine lining for possible malignancy, investigation of abnormal bleeding, and abortion. The World Health Organization recommends sharp curettage only when suction aspiration is unavailable. + +Dilation and evacuation (D&E), used after 12 to 16 weeks, consists of opening the cervix and emptying the uterus using surgical instruments and suction. D&E is performed vaginally and does not require an incision. Intact dilation and extraction (D&X) refers to a variant of D&E sometimes used after 18 to 20 weeks when removal of an intact fetus improves surgical safety or for other reasons. + +Abortion may also be performed surgically by hysterotomy or gravid hysterectomy. Hysterotomy abortion is a procedure similar to a caesarean section and is performed under general anesthesia. It requires a smaller incision than a caesarean section and can be used during later stages of pregnancy. Gravid hysterectomy refers to removal of the whole uterus while still containing the pregnancy. Hysterotomy and hysterectomy are associated with much higher rates of maternal morbidity and mortality than D&E or induction abortion. + +First trimester procedures can generally be performed using local anesthesia, while second trimester methods may require deep sedation or general anesthesia. + +Labor induction abortion +In places lacking the necessary medical skill for dilation and extraction, or when preferred by practitioners, an abortion can be induced by first inducing labor and then inducing fetal demise if necessary. This is sometimes called "induced miscarriage". This procedure may be performed from 13 weeks gestation to the third trimester. Although it is very uncommon in the United States, more than 80% of induced abortions throughout the second trimester are labor-induced abortions in Sweden and other nearby countries. + +Only limited data are available comparing labor-induced abortion with the dilation and extraction method. Unlike D&E, labor-induced abortions after 18 weeks may be complicated by the occurrence of brief fetal survival, which may be legally characterized as live birth. For this reason, labor-induced abortion is legally risky in the United States. + +Other methods +Historically, a number of herbs reputed to possess abortifacient properties have been used in folk medicine. Among these are: tansy, pennyroyal, black cohosh, and the now-extinct silphium. + +In 1978, one woman in Colorado died and another developed organ damage when they attempted to terminate their pregnancies by taking pennyroyal oil. +Because the indiscriminant use of herbs as abortifacients can cause serious—even lethal—side effects, such as multiple organ failure, such use is not recommended by physicians. + +Abortion is sometimes attempted by causing trauma to the abdomen. The degree of force, if severe, can cause serious internal injuries without necessarily succeeding in inducing miscarriage. In Southeast Asia, there is an ancient tradition of attempting abortion through forceful abdominal massage. One of the bas reliefs decorating the temple of Angkor Wat in Cambodia depicts a demon performing such an abortion upon a woman who has been sent to the underworld. + +Reported methods of unsafe, self-induced abortion include misuse of misoprostol and insertion of non-surgical implements such as knitting needles and clothes hangers into the uterus. These and other methods to terminate pregnancy may be called "induced miscarriage". Such methods are rarely used in countries where surgical abortion is legal and available. + +Safety + +The health risks of abortion depend principally upon whether the procedure is performed safely or unsafely. The World Health Organization (WHO) defines unsafe abortions as those performed by unskilled individuals, with hazardous equipment, or in unsanitary facilities. Legal abortions performed in the developed world are among the safest procedures in medicine. In the United States as of 2012, abortion was estimated to be about 14 times safer for women than childbirth. CDC estimated in 2019 that US pregnancy-related mortality was 17.2 maternal deaths per 100,000 live births, while the US abortion mortality rate is 0.7 maternal deaths per 100,000 procedures. In the UK, guidelines of the Royal College of Obstetricians and Gynaecologists state that "Women should be advised that abortion is generally safer than continuing a pregnancy to term." Worldwide, on average, abortion is safer than carrying a pregnancy to term. A 2007 study reported that "26% of all pregnancies worldwide are terminated by induced abortion," whereas "deaths from improperly performed [abortion] procedures constitute 13% of maternal mortality globally." In Indonesia in 2000 it was estimated that 2 million pregnancies ended in abortion, 4.5 million pregnancies were carried to term, and 14-16 percent of maternal deaths resulted from abortion. + +In the US from 2000 to 2009, abortion had a mortality rate lower than plastic surgery, lower or similar to running a marathon, and about equivalent to traveling in a passenger car. Five years after seeking abortion services, women who gave birth after being denied an abortion reported worse health than women who had either first or second trimester abortions. The risk of abortion-related mortality increases with gestational age, but remains lower than that of childbirth. Outpatient abortion is as safe from 64 to 70 days' gestation as it before 63 days. + +There is little difference in terms of safety and efficacy between medical abortion using a combined regimen of mifepristone and misoprostol and surgical abortion (vacuum aspiration) in early first trimester abortions up to 10 weeks gestation. Medical abortion using the prostaglandin analog misoprostol alone is less effective and more painful than medical abortion using a combined regimen of mifepristone and misoprostol or surgical abortion. + +Vacuum aspiration in the first trimester is the safest method of surgical abortion, and can be performed in a primary care office, abortion clinic, or hospital. Complications, which are rare, can include uterine perforation, pelvic infection, and retained products of conception requiring a second procedure to evacuate. Infections account for one-third of abortion-related deaths in the United States. The rate of complications of vacuum aspiration abortion in the first trimester is similar regardless of whether the procedure is performed in a hospital, surgical center, or office. Preventive antibiotics (such as doxycycline or metronidazole) are typically given before abortion procedures, as they are believed to substantially reduce the risk of postoperative uterine infection; however, antibiotics are not routinely given with abortion pills. The rate of failed procedures does not appear to vary significantly depending on whether the abortion is performed by a doctor or a mid-level practitioner. + +Complications after second trimester abortion are similar to those after first trimester abortion, and depend somewhat on the method chosen. The risk of death from abortion approaches roughly half the risk of death from childbirth the farther along a woman is in pregnancy; from one in a million before 9 weeks gestation to nearly one in ten thousand at 21 weeks or more (as measured from the last menstrual period). It appears that having had a prior surgical uterine evacuation (whether because of induced abortion or treatment of miscarriage) correlates with a small increase in the risk of preterm birth in future pregnancies. The studies supporting this did not control for factors not related to abortion or miscarriage, and hence the causes of this correlation have not been determined, although multiple possibilities have been suggested. + +Some purported risks of abortion are promoted primarily by anti-abortion groups, +but lack scientific support. For example, the question of a link between induced abortion and breast cancer has been investigated extensively. Major medical and scientific bodies (including the WHO, National Cancer Institute, American Cancer Society, Royal College of OBGYN and American Congress of OBGYN) have concluded that abortion does not cause breast cancer. + +In the past even illegality has not automatically meant that the abortions were unsafe. Referring to the U.S., historian Linda Gordon states: "In fact, illegal abortions in this country have an impressive safety record." According to Rickie Solinger, + +Authors Jerome Bates and Edward Zawadzki describe the case of an illegal abortionist in the eastern U.S. in the early 20th century who was proud of having successfully completed 13,844 abortions without any fatality. +In 1870s New York City the famous abortionist/midwife Madame Restell (Anna Trow Lohman) appears to have lost very few women among her more than 100,000 patients—a lower mortality rate than the childbirth mortality rate at the time. In 1936, the prominent professor of obstetrics and gynecology Frederick J. Taussig wrote that a cause of increasing mortality during the years of illegality in the U.S. was that + +Mental health + +Current evidence finds no relationship between most induced abortions and mental health problems other than those expected for any unwanted pregnancy. A report by the American Psychological Association concluded that a woman's first abortion is not a threat to mental health when carried out in the first trimester, with such women no more likely to have mental-health problems than those carrying an unwanted pregnancy to term; the mental-health outcome of a woman's second or greater abortion is less certain. Some older reviews concluded that abortion was associated with an increased risk of psychological problems; however, later reviews of the medical literature found that they did not use an appropriate control group. When a control group is utilized, receiving abortion is not associated with adverse psychological outcomes. However, women seeking abortion who are denied access to abortion have an increase in anxiety after the denial. + +Although some studies show negative mental-health outcomes in women who choose abortions after the first trimester because of fetal abnormalities, more rigorous research would be needed to show this conclusively. Some proposed negative psychological effects of abortion have been referred to by anti-abortion advocates as a separate condition called "post-abortion syndrome", but this is not recognized by medical or psychological professionals in the United States. + +A 2020 long term-study among US women found that about 99% of women felt that they made the right decision five years after they had an abortion. Relief was the primary emotion with few women feeling sadness or guilt. Social stigma was a main factor predicting negative emotions and regret years later. + +Unsafe abortion + +Women seeking an abortion may use unsafe methods, especially when it is legally restricted. They may attempt self-induced abortion or seek the help of a person without proper medical training or facilities. This can lead to severe complications, such as incomplete abortion, sepsis, hemorrhage, and damage to internal organs. + +Unsafe abortions are a major cause of injury and death among women worldwide. Although data are imprecise, it is estimated that approximately 20 million unsafe abortions are performed annually, with 97% taking place in developing countries. Unsafe abortions are believed to result in millions of injuries. Estimates of deaths vary according to methodology, and have ranged from 37,000 to 70,000 in the past decade; deaths from unsafe abortion account for around 13% of all maternal deaths. The World Health Organization believes that mortality has fallen since the 1990s. To reduce the number of unsafe abortions, public health organizations have generally advocated emphasizing the legalization of abortion, training of medical personnel, and ensuring access to reproductive-health services. + +A major factor in whether abortions are performed safely or not is the legal standing of abortion. Countries with restrictive abortion laws have higher rates of unsafe abortion and similar overall abortion rates compared to those where abortion is legal and available. For example, the 1996 legalization of abortion in South Africa had an immediate positive impact on the frequency of abortion-related complications, with abortion-related deaths dropping by more than 90%. Similar reductions in maternal mortality have been observed after other countries have liberalized their abortion laws, such as Romania and Nepal. A 2011 study concluded that in the United States, some state-level anti-abortion laws are correlated with lower rates of abortion in that state. The analysis, however, did not take into account travel to other states without such laws to obtain an abortion. In addition, a lack of access to effective contraception contributes to unsafe abortion. It has been estimated that the incidence of unsafe abortion could be reduced by up to 75% (from 20 million to 5 million annually) if modern family planning and maternal health services were readily available globally. Rates of such abortions may be difficult to measure because they can be reported variously as miscarriage, "induced miscarriage", "menstrual regulation", "mini-abortion", and "regulation of a delayed/suspended menstruation". + +Forty percent of the world's women are able to access therapeutic and elective abortions within gestational limits, while an additional 35 percent have access to legal abortion if they meet certain physical, mental, or socioeconomic criteria. While maternal mortality seldom results from safe abortions, unsafe abortions result in 70,000 deaths and 5 million disabilities per year. Complications of unsafe abortion account for approximately an eighth of maternal mortalities worldwide, though this varies by region. Secondary infertility caused by an unsafe abortion affects an estimated 24 million women. The rate of unsafe abortions has increased from 44% to 49% between 1995 and 2008. Health education, access to family planning, and improvements in health care during and after abortion have been proposed to address consequences of unsafe abortion. + +Incidence +There are two commonly used methods of measuring the incidence of abortion: + Abortion rate – number of abortions annually per 1,000 women between 15 and 44 years of age; some sources use a range of 15–49. + Abortion percentage – number of abortions out of 100 known pregnancies; pregnancies include live births, abortions, and miscarriages. + +In many places, where abortion is illegal or carries a heavy social stigma, medical reporting of abortion is not reliable. For this reason, estimates of the incidence of abortion must be made without determining certainty related to standard error. The number of abortions performed worldwide seems to have remained stable in the early 2000s, with 41.6 million having been performed in 2003 and 43.8 million having been performed in 2008. The abortion rate worldwide was 28 per 1000 women per year, though it was 24 per 1000 women per year for developed countries and 29 per 1000 women per year for developing countries. The same 2012 study indicated that in 2008, the estimated abortion percentage of known pregnancies was at 21% worldwide, with 26% in developed countries and 20% in developing countries. + +On average, the incidence of abortion is similar in countries with restrictive abortion laws and those with more liberal access to abortion. Restrictive abortion laws are associated with increases in the percentage of abortions performed unsafely. The unsafe abortion rate in developing countries is partly attributable to lack of access to modern contraceptives; according to the Guttmacher Institute, providing access to contraceptives would result in about 14.5 million fewer unsafe abortions and 38,000 fewer deaths from unsafe abortion annually worldwide. + +The rate of legal, induced abortion varies extensively worldwide. According to the report of employees of Guttmacher Institute it ranged from 7 per 1000 women per year (Germany and Switzerland) to 30 per 1000 women per year (Estonia) in countries with complete statistics in 2008. The proportion of pregnancies that ended in induced abortion ranged from about 10% (Israel, the Netherlands and Switzerland) to 30% (Estonia) in the same group, though it might be as high as 36% in Hungary and Romania, whose statistics were deemed incomplete. + +An American study in 2002 concluded that about half of women having abortions were using a form of contraception at the time of becoming pregnant. Inconsistent use was reported by half of those using condoms and three-quarters of those using the birth control pill; 42% of those using condoms reported failure through slipping or breakage. The Guttmacher Institute estimated that "most abortions in the United States are obtained by minority women" because minority women "have much higher rates of unintended pregnancy". In a 2022 analysis by the Kaiser Family Foundation, while people of color comprise 44% of the population in Mississippi, 59% of the population in Texas, 42% of the population in Louisiana (by the state Health Department), and 35% of the population in Alabama, they comprise 80%, 74%, 72%, and 70% of those receiving abortions. + +The abortion rate may also be expressed as the average number of abortions a woman has during her reproductive years; this is referred to as total abortion rate (TAR). + +Gestational age and method + +Abortion rates also vary depending on the stage of pregnancy and the method practiced. In 2003, the Centers for Disease Control and Prevention (CDC) reported that 26% of reported legal induced abortions in the United States were known to have been obtained at less than 6 weeks' gestation, 18% at 7 weeks, 15% at 8 weeks, 18% at 9 through 10 weeks, 10% at 11 through 12 weeks, 6% at 13 through 15 weeks, 4% at 16 through 20 weeks and 1% at more than 21 weeks. 91% of these were classified as having been done by "curettage" (suction-aspiration, dilation and curettage, dilation and evacuation), 8% by "medical" means (mifepristone), >1% by "intrauterine instillation" (saline or prostaglandin), and 1% by "other" (including hysterotomy and hysterectomy). According to the CDC, due to data collection difficulties the data must be viewed as tentative and some fetal deaths reported beyond 20 weeks may be natural deaths erroneously classified as abortions if the removal of the dead fetus is accomplished by the same procedure as an induced abortion. + +The Guttmacher Institute estimated there were 2,200 intact dilation and extraction procedures in the US during 2000; this accounts for <0.2% of the total number of abortions performed that year. Similarly, in England and Wales in 2006, 89% of terminations occurred at or under 12 weeks, 9% between 13 and 19 weeks, and 2% at or over 20 weeks. 64% of those reported were by vacuum aspiration, 6% by D&E, and 30% were medical. There are more second trimester abortions in developing countries such as China, India and Vietnam than in developed countries. + +There are both medical and non-medical reasons to have an abortion later in pregnancy (after 20 weeks). A study was conducted from 2008 to 2010 at the University of California San Francisco where more than 440 women were asked about why they experienced delays in obtaining abortion care, if there were any. This study found that almost half of individuals who obtained an abortion after 20 weeks did not suspect that they were pregnant until later in their pregnancy. Other barriers to abortion care found in the study included lack of information about where to access an abortion, difficulties with transportation, lack of insurance coverage, and inability to pay for the abortion procedure. + +Medical reasons for seeking an abortion later in pregnancy include fetal anomalies and health risk to the pregnant person. There are diagnostic tests that can diagnose Down Syndrome or cystic fibrosis as early as 10 weeks into gestation, but structural fetal anomalies are often detected much later in pregnancy. A proportion of structural fetal anomalies are lethal, which means that the fetus will almost certainly die before or shortly after birth. Life-threatening conditions may also develop later in pregnancy, such as early severe preeclampsia, newly diagnosed cancer in need of urgent treatment, and intrauterine infection (chorioamnionitis), which often occurs along with premature rupture of the amniotic sac (PPROM). If serious medical conditions such as these arise before the fetus is viable, the person carrying the pregnancy may pursue an abortion to preserve their own health. + +Motivation + +Personal + +The reasons why women have abortions are diverse and vary across the world. Some of the reasons may include an inability to afford a child, domestic violence, lack of support, feeling they are too young, and the wish to complete education or advance a career. Additional reasons include not being able or willing to raise a child conceived as a result of rape or incest. + +Societal +Some abortions are undergone as the result of societal pressures. These might include the preference for children of a specific sex or race, disapproval of single or early motherhood, stigmatization of people with disabilities, insufficient economic support for families, lack of access to or rejection of contraceptive methods, or efforts toward population control (such as China's one-child policy). These factors can sometimes result in compulsory abortion or sex-selective abortion. + +Maternal and fetal health +An additional factor is maternal health which was listed as the main reason by about a third of women in 3 of 27 countries and about 7% of women in a further 7 of these 27 countries. + +In the U.S., the Supreme Court decisions in Roe v. Wade and Doe v. Bolton: "ruled that the state's interest in the life of the fetus became compelling only at the point of viability, defined as the point at which the fetus can survive independently of its mother. Even after the point of viability, the state cannot favor the life of the fetus over the life or health of the pregnant woman. Under the right of privacy, physicians must be free to use their "medical judgment for the preservation of the life or health of the mother." On the same day that the Court decided Roe, it also decided Doe v. Bolton, in which the Court defined health very broadly: "The medical judgment may be exercised in the light of all factors—physical, emotional, psychological, familial, and the woman's age—relevant to the well-being of the patient. All these factors may relate to health. This allows the attending physician the room he needs to make his best medical judgment." + +Public opinion shifted in America following television personality Sherri Finkbine's discovery during her fifth month of pregnancy that she had been exposed to thalidomide. Unable to obtain a legal abortion in the United States, she traveled to Sweden. From 1962 to 1965, an outbreak of German measles left 15,000 babies with severe birth defects. In 1967, the American Medical Association publicly supported liberalization of abortion laws. A National Opinion Research Center poll in 1965 showed 73% supported abortion when the mother's life was at risk, 57% when birth defects were present and 59% for pregnancies resulting from rape or incest. + +Cancer + +The rate of cancer during pregnancy is 0.02–1%, and in many cases, cancer of the mother leads to consideration of abortion to protect the life of the mother, or in response to the potential damage that may occur to the fetus during treatment. This is particularly true for cervical cancer, the most common type of which occurs in 1 of every 2,000–13,000 pregnancies, for which initiation of treatment "cannot co-exist with preservation of fetal life (unless neoadjuvant chemotherapy is chosen)". Very early stage cervical cancers (I and IIa) may be treated by radical hysterectomy and pelvic lymph node dissection, radiation therapy, or both, while later stages are treated by radiotherapy. Chemotherapy may be used simultaneously. Treatment of breast cancer during pregnancy also involves fetal considerations, because lumpectomy is discouraged in favor of modified radical mastectomy unless late-term pregnancy allows follow-up radiation therapy to be administered after the birth. + +Exposure to a single chemotherapy drug is estimated to cause a 7.5–17% risk of teratogenic effects on the fetus, with higher risks for multiple drug treatments. Treatment with more than 40 Gy of radiation usually causes spontaneous abortion. Exposure to much lower doses during the first trimester, especially 8 to 15 weeks of development, can cause intellectual disability or microcephaly, and exposure at this or subsequent stages can cause reduced intrauterine growth and birth weight. Exposures above 0.005–0.025 Gy cause a dose-dependent reduction in IQ. It is possible to greatly reduce exposure to radiation with abdominal shielding, depending on how far the area to be irradiated is from the fetus. + +The process of birth itself may also put the mother at risk. According to Li et al., "[v]aginal delivery may result in dissemination of neoplastic cells into lymphovascular channels, haemorrhage, cervical laceration and implantation of malignant cells in the episiotomy site, while abdominal delivery may delay the initiation of non-surgical treatment." + +History and religion + +Since ancient times, abortions have been done using a number of methods, including herbal medicines acting as abortifacients, sharp tools through the use of force, or through other traditional medicine methods. Induced abortion has a long history and can be traced back to civilizations as varied as ancient China (abortifacient knowledge is often attributed to the mythological ruler Shennong), ancient India since its Vedic age, ancient Egypt with its Ebers Papyrus (), and the Roman Empire in the time of Juvenal (). One of the earliest known artistic representations of abortion is in a bas relief at Angkor Wat (). Found in a series of friezes that represent judgment after death in Hindu and Buddhist culture, it depicts the technique of abdominal abortion. + +In Judaism (), the fetus is not considered to have a human soul until it is safely outside of the woman, is viable, and has taken its first breath. The fetus is considered valuable property of the woman and not a human life while in the womb (). While Judaism encourages people to be fruitful and multiply by having children, abortion is allowed and is deemed necessary when a pregnant woman's life is in danger. Several religions, including Judaism, which disagree that human life begins at conception, support the legality of abortion on religious freedom grounds. In Islam, abortion is traditionally permitted until a point in time when Muslims believe the soul enters the fetus, considered by various theologians to be at conception, 40 days after conception, 120 days after conception, or quickening. Abortion is largely heavily restricted or forbidden in areas of high Islamic faith such as the Middle East and North Africa. + +Some medical scholars and abortion opponents have suggested that the Hippocratic Oath forbade physicians in Ancient Greece from performing abortions; other scholars disagree with this interpretation, and state that the medical texts of Hippocratic Corpus contain descriptions of abortive techniques right alongside the Oath. The physician Scribonius Largus wrote in 43 CE that the Hippocratic Oath prohibits abortion, as did Soranus of Ephesus, although apparently not all doctors adhered to it strictly at the time. According to Soranus' 1st or 2nd century CE work Gynaecology, one party of medical practitioners banished all abortives as required by the Hippocratic Oath; the other party to which he belonged was willing to prescribe abortions only for the sake of the mother's health. In Politics (350 BCE), Aristotle condemned infanticide as a means of population control. He preferred abortion in such cases, with the restriction that it "must be practised on it before it has developed sensation and life; for the line between lawful and unlawful abortion will be marked by the fact of having sensation and being alive." + +In the Catholic Church, opinion was divided on how serious abortion was in comparison with such acts as contraception, oral sex, and sex in marriage for pleasure rather than procreation. The Catholic Church did not begin vigorously opposing abortion until the 19th century. As early as ~100 CE, the Didache taught that abortion was sinful. Several historians argue that prior to the 19th century most Catholic authors did not regard termination of pregnancy before quickening or ensoulment as an abortion. Among these authors were the Doctors of the Church, such as St. Augustine, St. Thomas Aquinas, and St. Alphonsus Liguori. In 1588, Pope Sixtus V ( 1585–1590) was the only Pope before Pope Pius IX (in his 1869 bull, Apostolicae Sedis) to institute a Church policy labeling all abortion as homicide and condemning abortion regardless of the stage of pregnancy. Sixtus V's pronouncement was reversed in 1591 by Pope Gregory XIV. In the recodification of 1917 Code of Canon Law, Apostolicae Sedis was strengthened, in part to remove a possible reading that excluded excommunication of the mother. Statements made in the Catechism of the Catholic Church, the codified summary of the Church's teachings, considers abortion from the moment of conception as homicide and called for the end of legal abortion. + +Denominations that support abortion rights with some limits include the United Methodist Church, Episcopal Church, Evangelical Lutheran Church in America and Presbyterian Church USA. A 2014 Guttmacher survey of abortion patients in the United States found that many reported a religious affiliation: 24% were Catholic while 30% were Protestant. A 1995 survey reported that Catholic women are as likely as the general population to terminate a pregnancy, Protestants are less likely to do so, and evangelical Christians are the least likely to do so. A 2019 Pew Research Center study found that most Christian denominations were against overturning Roe v. Wade, which in the United States legalized abortion, at around 70%, except White Evangelicals at 35%. + +Abortion has been a fairly common practice, and was not always illegal or controversial until the 19th century. Under common law, including early English common law dating back to Edward Coke in 1648, abortion was generally permitted before quickening (14–26 weeks after conception, or between the fourth and sixth month), and at women's discretion; it was whether abortion was performed after quickening that determined if it was a crime. In Europe and North America, abortion techniques advanced starting in the 17th century; the conservatism of most in the medical profession with regards to sexual matters prevented the wide expansion of abortion techniques. Other medical practitioners in addition to some physicians advertised their services, and they were not widely regulated until the 19th century when the practice, sometimes called restellism, was banned in both the United States and the United Kingdom. + +Some 19th-century physicians, one of the most famous and consequential being American Horatio Storer, argued for anti-abortion laws on racist and misogynist as well as moral grounds. Church groups were also highly influential in anti-abortion movements, and religious groups more so since the 20th century. Some of the early anti-abortion laws punished only the doctor or abortionist, and while women could be criminally tried for a self-induced abortion, they were rarely prosecuted in general. In the United States, some argued that abortion was more dangerous than childbirth until about 1930 when incremental improvements in abortion procedures relative to childbirth made abortion safer. Others maintain that in the 19th century early abortions under the hygienic conditions in which midwives usually worked were relatively safe. Several scholars argue that, despite improved medical procedures, the period from the 1930s until the 1970s saw more zealous enforcement of anti-abortion laws, alongside an increasing control of abortion providers by organized crime. + +In 1920, Soviet Russia became the first country to legalize abortion after Lenin insisted that no woman be forced to give birth. Iceland (1935) and Sweden (1938) would follow suit to legalize certain or all forms of abortion. In Nazi Germany (1935), a law permitted abortions for those deemed "hereditarily ill", while women considered of German stock were specifically prohibited from having abortions. Beginning in the second half of the 20th century, abortion was legalized in a greater number of countries. In Japan, abortion was first legalized by the 1948 "Eugenics Protection Law" meant to prevent the births of "inferior" humans. , due to Japan's continuing strongly patriarchal culture and traditional views on women's societal roles, women who want an abortion must normally get written permission from their partner. + +Society and culture + +Abortion debate + +Induced abortion has long been the source of considerable debate. Ethical, moral, philosophical, biological, religious and legal issues surrounding abortion are related to value systems. Opinions of abortion may be about fetal rights, governmental authority, and women's rights. + +In both public and private debate, arguments presented in favor of or against abortion access focus on either the moral permissibility of an induced abortion, or the justification of laws permitting or restricting abortion. The World Medical Association Declaration on Therapeutic Abortion notes, "circumstances bringing the interests of a mother into conflict with the interests of her unborn child create a dilemma and raise the question as to whether or not the pregnancy should be deliberately terminated." Abortion debates, especially pertaining to abortion laws, are often spearheaded by groups advocating one of these two positions. Groups who favor greater legal restrictions on abortion, including complete prohibition, most often describe themselves as "pro-life" while groups who are against such legal restrictions describe themselves as "pro-choice". + +Modern abortion law + +Current laws pertaining to abortion are diverse. Religious, moral, and cultural factors continue to influence abortion laws throughout the world. The right to life, the right to liberty, the right to security of person, and the right to reproductive health are major issues of human rights that sometimes constitute the basis for the existence or absence of abortion laws. + +In jurisdictions where abortion is legal, certain requirements must often be met before a woman may obtain a legal abortion (an abortion performed without the woman's consent is considered feticide). These requirements usually depend on the age of the fetus, often using a trimester-based system to regulate the window of legality, or as in the U.S., on a doctor's evaluation of the fetus' viability. Some jurisdictions require a waiting period before the procedure, prescribe the distribution of information on fetal development, or require that parents be contacted if their minor daughter requests an abortion. Other jurisdictions may require that a woman obtain the consent of the fetus' father before aborting the fetus, that abortion providers inform women of health risks of the procedure—sometimes including "risks" not supported by the medical literature—and that multiple medical authorities certify that the abortion is either medically or socially necessary. Many restrictions are waived in emergency situations. China, which has ended their one-child policy, and now has a two child policy, has at times incorporated mandatory abortions as part of their population control strategy. + +Other jurisdictions ban abortion almost entirely. Many, but not all, of these allow legal abortions in a variety of circumstances. These circumstances vary based on jurisdiction, but may include whether the pregnancy is a result of rape or incest, the fetus' development is impaired, the woman's physical or mental well-being is endangered, or socioeconomic considerations make childbirth a hardship. In countries where abortion is banned entirely, such as Nicaragua, medical authorities have recorded rises in maternal death directly and indirectly due to pregnancy as well as deaths due to doctors' fears of prosecution if they treat other gynecological emergencies. Some countries, such as Bangladesh, that nominally ban abortion, may also support clinics that perform abortions under the guise of menstrual hygiene. This is also a terminology in traditional medicine. In places where abortion is illegal or carries heavy social stigma, pregnant women may engage in medical tourism and travel to countries where they can terminate their pregnancies. Women without the means to travel can resort to providers of illegal abortions or attempt to perform an abortion by themselves. + +The organization Women on Waves has been providing education about medical abortions since 1999. The NGO created a mobile medical clinic inside a shipping container, which then travels on rented ships to countries with restrictive abortion laws. Because the ships are registered in the Netherlands, Dutch law prevails when the ship is in international waters. While in port, the organization provides free workshops and education; while in international waters, medical personnel are legally able to prescribe medical abortion drugs and counseling. + +Sex-selective abortion + +Sonography and amniocentesis allow parents to determine sex before childbirth. The development of this technology has led to sex-selective abortion, or the termination of a fetus based on its sex. The selective termination of a female fetus is most common. + +Sex-selective abortion is partially responsible for the noticeable disparities between the birth rates of male and female children in some countries. The preference for male children is reported in many areas of Asia, and abortion used to limit female births has been reported in Taiwan, South Korea, India, and China. This deviation from the standard birth rates of males and females occurs despite the fact that the country in question may have officially banned sex-selective abortion or even sex-screening. In China, a historical preference for a male child has been exacerbated by the one-child policy, which was enacted in 1979. + +Many countries have taken legislative steps to reduce the incidence of sex-selective abortion. At the International Conference on Population and Development in 1994 over 180 states agreed to eliminate "all forms of discrimination against the girl child and the root causes of son preference", conditions also condemned by a PACE resolution in 2011. The World Health Organization and UNICEF, along with other United Nations agencies, have found that measures to restrict access to abortion in an effort to reduce sex-selective abortions have unintended negative consequences, largely stemming from the fact that women may seek or be coerced into seeking unsafe, extralegal abortions. On the other hand, measures to reduce gender inequality can reduce the prevalence of such abortions without attendant negative consequences. + +Anti-abortion violence + +In a number of cases, abortion providers and these facilities have been subjected to various forms of violence, including murder, attempted murder, kidnapping, stalking, assault, arson, and bombing. Anti-abortion violence is classified by both governmental and scholarly sources as terrorism. In the U.S. and Canada, over 8,000 incidents of violence, trespassing, and death threats have been recorded by providers since 1977, including over 200 bombings/arsons and hundreds of assaults. The majority of abortion opponents have not been involved in violent acts. + +In the United States, four physicians who performed abortions have been murdered: David Gunn (1993), John Britton (1994), Barnett Slepian (1998), and George Tiller (2009). Also murdered, in the U.S. and Australia, have been other personnel at abortion clinics, including receptionists and security guards such as James Barrett, Shannon Lowney, Lee Ann Nichols, and Robert Sanderson. Woundings (e.g., Garson Romalis) and attempted murders have also taken place in the United States and Canada. Hundreds of bombings, arsons, acid attacks, invasions, and incidents of vandalism against abortion providers have occurred. Notable perpetrators of anti-abortion violence include Eric Robert Rudolph, Scott Roeder, Shelley Shannon, and Paul Jennings Hill, the first person to be executed in the United States for murdering an abortion provider. + +Legal protection of access to abortion has been brought into some countries where abortion is legal. These laws typically seek to protect abortion clinics from obstruction, vandalism, picketing, and other actions, or to protect women and employees of such facilities from threats and harassment. + +Far more common than physical violence is psychological pressure. In 2003, Chris Danze organized anti-abortion organizations throughout Texas to prevent the construction of a Planned Parenthood facility in Austin. The organizations released the personal information online of those involved with construction, sent them up to 1200 phone calls a day and contacted their churches. Some protestors record women entering clinics on camera. + +Non-human examples + +Spontaneous abortion occurs in various animals. For example, in sheep it may be caused by stress or physical exertion, such as crowding through doors or being chased by dogs. In cows, abortion may be caused by contagious disease, such as brucellosis or Campylobacter, but can often be controlled by vaccination. Eating pine needles can also induce abortions in cows. Several plants, including broomweed, skunk cabbage, poison hemlock, and tree tobacco, are known to cause fetal deformities and abortion in cattle and in sheep and goats. In horses, a fetus may be aborted or resorbed if it has lethal white syndrome (congenital intestinal aganglionosis). Foal embryos that are homozygous for the dominant white gene (WW) are theorized to also be aborted or resorbed before birth. In many species of sharks and rays, stress-induced abortions occur frequently on capture. + +Viral infection can cause abortion in dogs. Cats can experience spontaneous abortion for many reasons, including hormonal imbalance. A combined abortion and spaying is performed on pregnant cats, especially in trap–neuter–return programs, to prevent unwanted kittens from being born. Female rodents may terminate a pregnancy when exposed to the smell of a male not responsible for the pregnancy, known as the Bruce effect. + +Abortion may also be induced in animals, in the context of animal husbandry. For example, abortion may be induced in mares that have been mated improperly, or that have been purchased by owners who did not realize the mares were pregnant, or that are pregnant with twin foals. Feticide can occur in horses and zebras due to male harassment of pregnant mares or forced copulation, although the frequency in the wild has been questioned. Male gray langur monkeys may attack females following male takeover, causing miscarriage. + +See also +Abortion doula +Forced abortion +Indirect abortion + +Notes + +References + +Bibliography + +External links + + First-trimester abortion in women with medical conditions.

Fighting began on April 19, 1775, at the Battles of Lexington and Concord. The war was formalized and intensified following passage of the Lee Resolution, which asserted that the Thirteen Colonies were "free and independent states", by the Second Continental Congress in Philadelphia on July 2, 1776, and the unanimous ratification of the Declaration of Independence two days later, on July 4, 1776. + +American patriot forces eventually gained the support of the Kingdom of France and the Kingdom of Spain. The British and Loyalist forces also included Hessian soldiers from Germany. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. + +The American colonies were established by royal charter in the 17th and 18th centuries. They were initially largely autonomous in domestic affairs and commercially prosperous, trading with Britain, its Caribbean colonies, and other European powers via their Caribbean entrepôts. After the British gained victory over the French in the Seven Years' War in 1763, tensions and disputes arose between Britain and the colonies over the lack of political representation in the homeland and policies related to trade, trans-Appalachian settlement, and taxation, including the Stamp and Townshend Acts. Resulting British military occupation led to the Boston Massacre in 1770, which strengthened American Patriots' desire for independence from Britain. The British responded by repealing earlier taxation measures, but in 1773, the British Parliament adopted the Tea Act to demonstrate supremacy, a measure which led to the Boston Tea Party on December 16, 1773. In response, the British Parliament imposed the Intolerable Acts in mid-1774, closed Boston Harbor, and revoked Massachusetts' charter, which placed the colony under the British monarchy's direct governance. + +These measures rallied the other colonies, 12 of which sent delegates to the First Continental Congress in Philadelphia in early September 1774 to protest the measures and deliberate on potential responses. The Congress drafted a Petition to the King asking for peace, and threatened a boycott of British goods known as the Continental Association if the Intolerable Acts were not withdrawn. The British attempted to disarm the Americans and the resulting fighting at the Battle of Lexington on April 19, 1775, in effect ignited the war. In June, the Second Continental Congress formalized Patriot militias into the Continental Army and appointed George Washington its commander-in-chief. The coercion policy advocated by the North ministry was opposed by a faction within the British Parliament, but both sides began to see military conflict as inevitable. Congress sent the Olive Branch Petition to King George III in July 1775, but he rejected it, and the British Parliament declared the colonies to be in a state of rebellion in August. + +As the Revolutionary War formally launched, Washington's forces drove the British army out of Boston during the Siege of Boston in March 1776, and British commander in chief William Howe responded by launching the New York and New Jersey campaign. Howe captured New York City in November, and Washington responded by clandestinely crossing the Delaware River and winning small but significant victories at Trenton and Princeton, which restored Patriot confidence. In summer 1777, as Howe was poised to capture Philadelphia, the Continental Congress prepared for Philadelphia's fall by fleeing the city for Baltimore. + +In October 1777, a separate British force under the command of John Burgoyne was forced to surrender at Saratoga in an American victory that proved crucial in convincing France and Spain that an independent United States was a viable possibility. With Philadelphia still occupied by the British, Washington and 12,000 Continental Army troops secured refuge in Valley Forge from December 1777 to June 1778. At Valley Forge, General von Steuben drilled the Continental Army into a more viable fighting unit, but as many as 2,000 Continental Army troops died from disease and possibly malnutrition over a brutal winter. + +France provided the Continental Army with informal economic and military support from the beginning of the war. After Saratoga, the two countries signed a commercial agreement and a Treaty of Alliance in February 1778. In 1779, Spain also allied with France against Britain in the Treaty of Aranjuez, though Spain did not formally ally with the Americans. Access to ports in Spanish Louisiana allowed American patriots to import arms and supplies, while the Spanish Gulf Coast campaign deprived the British Royal Navy of key bases in the American south. + +Closure of American ports undermined the 1778 strategy devised by Howe's replacement Henry Clinton, which intended to take the war against the Americans into the south. Despite some initial success, Cornwallis was besieged by a Franco-American force in Yorktown in September and October 1781. Cornwallis attempted to resupply the garrison, but failed and was forced to surrender in October. The British wars with France and Spain continued for another two years, but Britain's forces in America were largely confined to several harbors and forts in Great Lakes, and fighting largely ceased in America. In April 1782, the North ministry was replaced by a new British government, which accepted American independence and began negotiating the Treaty of Paris, ratified on September 3, 1783, and Britain acknowledged the sovereignty and independence of the United States of America, bringing the American Revolutionary War to an end. The Treaties of Versailles resolved Britain's conflicts with France and Spain. + +Prelude to revolution + +The French and Indian War, part of the wider global conflict known as the Seven Years' War, ended with the 1763 Peace of Paris, which expelled France from Britain's possessions in New France. Acquisition of territories in Atlantic Canada and West Florida, inhabited largely by French or Spanish-speaking Catholics, led British authorities to consolidate their hold by populating them with English-speaking settlers. Preventing conflict between settlers and Indian tribes west of the Appalachian Mountains also avoided the cost of an expensive military occupation. + +The Royal Proclamation of 1763 was designed to achieve these aims by refocusing colonial expansion north into Nova Scotia and south into Florida, with the Mississippi River as the dividing line between British and Spanish possessions in America. Settlement was tightly restricted beyond the 1763 limits, and claims west of this line, including by Virginia and Massachusetts, were rescinded despite the fact that each colony argued that their boundaries extended from the Atlantic Ocean to the Pacific Ocean. + +The vast exchange of territory ultimately destabilized existing alliances and trade networks between settlers and Indians in the west, while it proved impossible to prevent encroachment beyond the Proclamation Line. With the exception of Virginia and others deprived of rights to western lands, the colonial legislatures agreed on the boundaries but disagreed on where to set them. Many settlers resented the restrictions entirely, and enforcement required permanent garrisons along the frontier, which led to increasingly bitter disputes over who should pay for them. + +Taxation and legislation + +Although directly administered by The Crown, acting through a local governor, the colonies were largely governed by native-born property owners. While external affairs were managed by London, colonial militia were funded locally but with the ending of the French threat in 1763, the legislatures expected less taxation, not more. At the same time, the huge debt incurred by the Seven Years' War and demands from British taxpayers for cuts in government expenditure meant Parliament expected the colonies to fund their own defense. + +The 1763 to 1765 Grenville ministry instructed the Royal Navy to cease trading smuggled goods and enforce customs duties levied in American ports. The most important was the 1733 Molasses Act; routinely ignored prior to 1763, it had a significant economic impact since 85% of New England rum exports were manufactured from imported molasses. These measures were followed by the Sugar Act and Stamp Act, which imposed additional taxes on the colonies to pay for defending the western frontier. In July 1765, the Whigs formed the First Rockingham ministry, which repealed the Stamp Act and reduced tax on foreign molasses to help the New England economy, but re-asserted Parliamentary authority in the Declaratory Act. + +However, this did little to end the discontent; in 1768, a riot started in Boston when the authorities seized the sloop Liberty on suspicion of smuggling. Tensions escalated further in March 1770 when British troops fired on rock-throwing civilians, killing five in what became known as the Boston Massacre. The Massacre coincided with the partial repeal of the Townshend Acts by the Tory-based North Ministry, which came to power in January 1770 and remained in office until 1781. North insisted on retaining duty on tea to enshrine Parliament's right to tax the colonies; the amount was minor, but ignored the fact it was that very principle Americans found objectionable. + +Tensions escalated following the destruction of a customs vessel in the June 1772 Gaspee Affair, then came to a head in 1773. A banking crisis led to the near-collapse of the East India Company, which dominated the British economy; to support it, Parliament passed the Tea Act, giving it a trading monopoly in the Thirteen Colonies. Since most American tea was smuggled by the Dutch, the act was opposed by those who managed the illegal trade, while being seen as yet another attempt to impose the principle of taxation by Parliament. In December 1773, a group called the Sons of Liberty disguised as Mohawk natives dumped 342 crates of tea into Boston Harbor, an event later known as the Boston Tea Party. The British Parliament responded by passing the so-called Intolerable Acts, aimed specifically at Massachusetts, although many colonists and members of the Whig opposition considered them a threat to liberty in general. This led to increased sympathy for the Patriot cause locally, in British Parliament, and in the London press. + +Break with the British Crown + +Throughout the 18th century, the elected lower houses in the colonial legislatures gradually wrested power from their royal governors. Dominated by smaller landowners and merchants, these assemblies now established ad-hoc provincial legislatures, variously called congresses, conventions, and conferences, effectively replacing royal control. With the exception of Georgia, twelve colonies sent representatives to the First Continental Congress to agree on a unified response to the crisis. Many of the delegates feared that an all-out boycott would result in war and sent a Petition to the King calling for the repeal of the Intolerable Acts. However, after some debate, on September 17, 1774, Congress endorsed the Massachusetts Suffolk Resolves and on October 20 passed the Continental Association; based on a draft prepared by the First Virginia Convention in August, the association instituted economic sanctions and a full boycott of goods against Britain. + +While denying its authority over internal American affairs, a faction led by James Duane and future Loyalist Joseph Galloway insisted Congress recognize Parliament's right to regulate colonial trade. Expecting concessions by the North administration, Congress authorized the extralegal committees and conventions of the colonial legislatures to enforce the boycott; this succeeded in reducing British imports by 97% from 1774 to 1775. However, on February 9 Parliament declared Massachusetts to be in a state of rebellion and instituted a blockade of the colony. In July, the Restraining Acts limited colonial trade with the British West Indies and Britain and barred New England ships from the Newfoundland cod fisheries. The increase in tension led to a scramble for control of militia stores, which each assembly was legally obliged to maintain for defense. On April 19, a British attempt to secure the Concord arsenal culminated in the Battles of Lexington and Concord, which began the Revolutionary War. + +Political reactions + +After the Patriot victory at Concord, moderates in Congress led by John Dickinson drafted the Olive Branch Petition, offering to accept royal authority in return for George III mediating in the dispute. However, since the petition was immediately followed by the Declaration of the Causes and Necessity of Taking Up Arms, Colonial Secretary Lord Dartmouth viewed the offer as insincere; he refused to present the petition to the king, which was therefore rejected in early September. Although constitutionally correct, since George could not oppose his own government, it disappointed those Americans who hoped he would mediate in the dispute, while the hostility of his language annoyed even Loyalist members of Congress. Combined with the Proclamation of Rebellion, issued on August 23 in response to the Battle at Bunker Hill, it ended hopes of a peaceful settlement. + +Backed by the Whigs, Parliament initially rejected the imposition of coercive measures by 170 votes, fearing an aggressive policy would simply drive the Americans towards independence. However, by the end of 1774 the collapse of British authority meant both Lord North and George III were convinced war was inevitable. After Boston, Gage halted operations and awaited reinforcements; the Irish Parliament approved the recruitment of new regiments, while allowing Catholics to enlist for the first time. Britain also signed a series of treaties with German states to supply additional troops. Within a year, it had an army of over 32,000 men in America, the largest ever sent outside Europe at the time. The employment of German soldiers against people viewed as British citizens was opposed by many in Parliament and by the colonial assemblies; combined with the lack of activity by Gage, opposition to the use of foreign troops allowed the Patriots to take control of the legislatures. + +Declaration of Independence + +Support for independence was boosted by Thomas Paine's pamphlet Common Sense, which was published January 10, 1776 and argued for American self-government and was widely reprinted. To draft the Declaration of Independence, the Second Continental Congress appointed the Committee of Five, consisting of Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston. The declaration was written almost exclusively by Jefferson, who wrote it largely in isolation between June 11 and June 28, 1776, in a three-story residence at 700 Market Street in Philadelphia. + +Identifying inhabitants of the Thirteen Colonies as "one people", the declaration simultaneously dissolved political links with Britain, while including a long list of alleged violations of "English rights" committed by George III. This is also one of the foremost times that the colonies were referred to as "United States", rather than the more common United Colonies. + +On July 2, Congress voted for independence and published the declaration on July 4, which Washington read to his troops in New York City on July 9. At this point, the revolution ceased to be an internal dispute over trade and tax policies and had evolved into a civil war, since each state represented in Congress was engaged in a struggle with Britain, but also split between American Patriots and American Loyalists. Patriots generally supported independence from Britain and a new national union in Congress, while Loyalists remained faithful to British rule. Estimates of numbers vary, one suggestion being the population as a whole was split evenly between committed Patriots, committed Loyalists, and those who were indifferent. Others calculate the split as 40% Patriot, 40% neutral, 20% Loyalist, but with considerable regional variations. + +At the onset of the war, the Second Continental Congress realized defeating Britain required foreign alliances and intelligence-gathering. The Committee of Secret Correspondence was formed for "the sole purpose of corresponding with our friends in Great Britain and other parts of the world". From 1775 to 1776, the committee shared information and built alliances through secret correspondence, as well as employing secret agents in Europe to gather intelligence, conduct undercover operations, analyze foreign publications, and initiate Patriot propaganda campaigns. Paine served as secretary, while Benjamin Franklin and Silas Deane, sent to France to recruit military engineers, were instrumental in securing French aid in Paris. + +War breaks out +The Revolutionary War included two principal campaign theaters within the Thirteen Colonies, and a smaller but strategically important third one west of the Appalachian Mountains. Fighting began in the Northern Theater and was at its most severe from 1775 to 1778. American patriots achieved several strategic victories in the South. The Americans defeated the British Army at Saratoga in October 1777, and the French, seeing the possibility for an American patriot victory in the war, formally entered the war as an American ally. + +During 1778, Washington prevented the British army from breaking out of New York City, while militia under George Rogers Clark conquered Western Quebec, supported by Francophone settlers and their Indian allies, which became the Northwest Territory. The war became a stalemate in the north in 1779, so the British initiated their southern strategy, which aimed to mobilize Loyalist support in the region and occupy American patriot-controlled territory north to Chesapeake Bay. The campaign was initially successful, with the British capture of Charleston being a major setback for southern Patriots; however, a Franco-American force surrounded the British army at Yorktown and their surrender in October 1781 effectively ended fighting in America. + +Early engagements + +On April 14, 1775, Sir Thomas Gage, Commander-in-Chief, North America since 1763 and also Governor of Massachusetts from 1774, received orders to take action against the Patriots. He decided to destroy militia ordnance stored at Concord, Massachusetts, and capture John Hancock and Samuel Adams, who were considered the principal instigators of the rebellion. The operation was to begin around midnight on April 19, in the hope of completing it before the American patriots could respond. However, Paul Revere learned of the plan and notified Captain Parker, commander of the Concord militia, who prepared to resist the attempted seizure. The first action of the war, commonly referred to as the shot heard round the world, was a brief skirmish at Lexington, followed by the full-scale Battles of Lexington and Concord. British troops suffered around 300 casualties before withdrawing to Boston, which was then besieged by the militia. + +In May 1775, 4,500 British reinforcements arrived under Generals William Howe, John Burgoyne, and Sir Henry Clinton. On June 17, they seized the Charlestown Peninsula at the Battle of Bunker Hill, a frontal assault in which they suffered over 1,000 casualties. Dismayed at the costly attack which had gained them little, Gage appealed to London for a larger army to suppress the revolt, but instead was replaced as commander by Howe. + +On June 14, 1775, Congress took control of American patriot forces outside Boston, and Congressional leader John Adams nominated George Washington as commander-in-chief of the newly formed Continental Army. Washington previously commanded Virginia militia regiments in the French and Indian War, and on June 16, John Hancock officially proclaimed him "General and Commander in Chief of the army of the United Colonies." He assumed command on July 3, preferring to fortify Dorchester Heights outside Boston rather than assaulting it. In early March 1776, Colonel Henry Knox arrived with heavy artillery acquired in the Capture of Fort Ticonderoga. Under cover of darkness, on March 5, Washington placed these on Dorchester Heights, from where they could fire on the town and British ships in Boston Harbor. Fearing another Bunker Hill, Howe evacuated the city on March 17 without further loss and sailed to Halifax, Nova Scotia, while Washington moved south to New York City. + +Beginning in August 1775, American privateers raided towns in Nova Scotia, including Saint John, Charlottetown, and Yarmouth. In 1776, John Paul Jones and Jonathan Eddy attacked Canso and Fort Cumberland respectively. British officials in Quebec began negotiating with the Iroquois for their support, while US envoys urged them to remain neutral. Aware of Native American leanings toward the British and fearing an Anglo-Indian attack from Canada, Congress authorized a second invasion in April 1775. After defeat at the Battle of Quebec on December 31, the Americans maintained a loose blockade of the city until they retreated on May 6, 1776. A second defeat at Trois-Rivières on June 8 ended operations in Quebec. + +British pursuit was initially blocked by American naval vessels on Lake Champlain until victory at Valcour Island on October 11 forced the Americans to withdraw to Fort Ticonderoga, while in December an uprising in Nova Scotia sponsored by Massachusetts was defeated at Fort Cumberland. These failures impacted public support for the Patriot cause, and aggressive anti-Loyalist policies in the New England colonies alienated the Canadians. + +In Virginia, an attempt by Governor Lord Dunmore to seize militia stores on April 20, 1775, led to an increase in tension, although conflict was avoided for the time being. This changed after the publication of Dunmore's Proclamation on November 7, 1775, promising freedom to any slaves who fled their Patriot masters and agreed to fight for the Crown. British forces were defeated at Great Bridge on December 9 and took refuge on British ships anchored near the port of Norfolk. When the Third Virginia Convention refused to disband its militia or accept martial law, Dunmore ordered the Burning of Norfolk on January 1, 1776. + +The siege of Savage's Old Fields began on November 19 in South Carolina between Loyalist and Patriot militias, and the Loyalists were subsequently driven out of the colony in the Snow Campaign. Loyalists were recruited in North Carolina to reassert British rule in the South, but they were decisively defeated in the Battle of Moore's Creek Bridge. A British expedition sent to reconquer South Carolina launched an attack on Charleston in the Battle of Sullivan's Island on June 28, 1776, but it failed and left the South under Patriot control until 1780. + +A shortage of gunpowder led Congress to authorize a naval expedition against The Bahamas to secure ordnance stored there. On March 3, 1776, an American squadron under the command of Esek Hopkins landed at the east end of Nassau and encountered minimal resistance at Fort Montagu. Hopkins' troops then marched on Fort Nassau. Hopkins had promised governor Montfort Browne and the civilian inhabitants of the area that their lives and property would not be in any danger if they offered no resistance, to which they complied. Hopkins captured large stores of powder and other munitions that was so great he had to impress an extra ship in the harbor to transport the supplies back home, when he departed on March 17. A month later, after a brief skirmish with , they returned to New London, Connecticut, the base for American naval operations during the Revolution. + +British New York counter-offensive + +After regrouping at Halifax in Nova Scotia, Howe was determined to take the fight to the Americans. He set sail for New York in June 1776 and began landing troops on Staten Island near the entrance to New York Harbor on July 2. The Americans rejected Howe's informal attempt to negotiate peace on July 30; Washington knew that an attack on the city was imminent and realized that he needed advance information to deal with disciplined British regular troops. + +On August 12, 1776, Patriot Thomas Knowlton was given orders to form an elite group for reconnaissance and secret missions. Knowlton's Rangers, which included Nathan Hale, became the Army's first intelligence unit. When Washington was driven off Long Island, he soon realized that he would need more than military might and amateur spies to defeat the British. He was committed to professionalizing military intelligence. With aid from Benjamin Tallmadge, Washington launched the six-man Culper spy ring. The efforts of Washington and the Culper Spy Ring substantially increased effective allocation and deployment of Continental regiments in the field. Over the course of the war, Washington spent more than 10 percent of his total military funds on military intelligence operations. + +Washington split the Continental Army into positions on Manhattan and across the East River in western Long Island. On August 27 at the Battle of Long Island, Howe outflanked Washington and forced him back to Brooklyn Heights, but he did not attempt to encircle Washington's forces. Through the night of August 28, General Henry Knox bombarded the British. Knowing they were up against overwhelming odds, Washington ordered the assembly of a war council on August 29; all agreed to retreat to Manhattan. Washington quickly had his troops assembled and ferried them across the East River to Manhattan on flat-bottomed freight boats without any losses in men or ordnance, leaving General Thomas Mifflin's regiments as a rearguard. + +Howe met with a delegation from the Second Continental Congress at the September Staten Island Peace Conference, but it failed to conclude peace, largely because the British delegates only had authority to offer pardons and could not recognize independence. On September 15, Howe seized control of New York City when the British landed at Kip's Bay and unsuccessfully engaged the Americans at the Battle of Harlem Heights the following day. On October 18, Howe failed to encircle the Americans at the Battle of Pell's Point, and the Americans withdrew. Howe declined to close with Washington's army on October 28 at the Battle of White Plains, and instead attacked a hill that was of no strategic value. + +Washington's retreat isolated his remaining forces and the British captured Fort Washington on November 16. The British victory there amounted to Washington's most disastrous defeat with the loss of 3,000 prisoners. The remaining American regiments on Long Island fell back four days later. General Henry Clinton wanted to pursue Washington's disorganized army, but he was first required to commit 6,000 troops to capture Newport, Rhode Island to secure the Loyalist port. General Charles Cornwallis pursued Washington, but Howe ordered him to halt, leaving Washington unmolested. + +The outlook following the defeat at Fort Washington appeared bleak for the American cause. The reduced Continental Army had dwindled to fewer than 5,000 men and was reduced further when enlistments expired at the end of the year. Popular support wavered, and morale declined. On December 20, 1776, the Continental Congress abandoned the revolutionary capital of Philadelphia and moved to Baltimore, where it remained for over two months, until February 27, 1777. Loyalist activity surged in the wake of the American defeat, especially in New York state. + +In London, news of the victorious Long Island campaign was well received with festivities held in the capital. Public support reached a peak, and King George III awarded the Order of the Bath to Howe. Strategic deficiencies among Patriot forces were evident: Washington divided a numerically weaker army in the face of a stronger one, his inexperienced staff misread the military situation, and American troops fled in the face of enemy fire. The successes led to predictions that the British could win within a year. In the meantime, the British established winter quarters in the New York City area and anticipated renewed campaigning the following spring. + +Patriot resurgence + +Two weeks after Congress withdrew to Baltimore, on the night of December 25–26, 1776, Washington crossed the Delaware River, leading a column of Continental Army troops from today's Bucks County, Pennsylvania, located about 30 miles upriver from Philadelphia, to today's Mercer County, New Jersey, in a logistically challenging and dangerous operation. + +Meanwhile, the Hessians were involved with numerous clashes with small bands of patriots and were often aroused by false alarms at night in the weeks before the actual Battle of Trenton. By Christmas they were tired and weary, while a heavy snow storm led their commander, Colonel Johann Rall, to assume no attack of any consequence would occur. At daybreak on the 26th, the American patriots surprised and overwhelmed Rall and his troops, who lost over 20 killed including Rall, while 900 prisoners, German cannons and much supply were captured. + +The Battle of Trenton restored the American army's morale, reinvigorated the Patriot cause, and dispelled their fear of what they regarded as Hessian "mercenaries". A British attempt to retake Trenton was repulsed at Assunpink Creek on January 2; during the night, Washington outmaneuvered Cornwallis, then defeated his rearguard in the Battle of Princeton the following day. The two victories helped convince the French that the Americans were worthy military allies. + +After his success at Princeton, Washington entered winter quarters at Morristown, New Jersey, where he remained until May and received Congressional direction to inoculate all patriot troops against smallpox. With the exception of a minor skirmishing between the two armies which continued until March, Howe made no attempt to attack the Americans. + +British northern strategy fails + +The 1776 campaign demonstrated that regaining New England would be a prolonged affair, which led to a change in British strategy. This involved isolating the north from the rest of the country by taking control of the Hudson River, allowing them to focus on the south where Loyalist support was believed to be substantial. In December 1776, Howe wrote to the Colonial Secretary Lord Germain, proposing a limited offensive against Philadelphia, while a second force moved down the Hudson from Canada. Germain received this on February 23, 1777, followed a few days later by a memorandum from Burgoyne, then in London on leave. + +Burgoyne supplied several alternatives, all of which gave him responsibility for the offensive, with Howe remaining on the defensive. The option selected required him to lead the main force south from Montreal down the Hudson Valley, while a detachment under Barry St. Leger moved east from Lake Ontario. The two would meet at Albany, leaving Howe to decide whether to join them. Reasonable in principle, this did not account for the logistical difficulties involved and Burgoyne erroneously assumed Howe would remain on the defensive; Germain's failure to make this clear meant he opted to attack Philadelphia instead. + +Burgoyne set out on June 14, 1777, with a mixed force of British regulars, professional German soldiers and Canadian militia, and captured Fort Ticonderoga on July 5. As General Horatio Gates retreated, his troops blocked roads, destroyed bridges, dammed streams, and stripped the area of food. This slowed Burgoyne's progress and forced him to send out large foraging expeditions; on one of these, more than 700 British troops were captured at the Battle of Bennington on August 16. St Leger moved east and besieged Fort Stanwix; despite defeating an American relief force at the Battle of Oriskany on August 6, he was abandoned by his Indian allies and withdrew to Quebec on August 22. Now isolated and outnumbered by Gates, Burgoyne continued onto Albany rather than retreating to Fort Ticonderoga, reaching Saratoga on September 13. He asked Clinton for support while constructing defenses around the town. + +Morale among his troops rapidly declined, and an unsuccessful attempt to break past Gates at the Battle of Freeman Farms on September 19 resulted in 600 British casualties. When Clinton advised he could not reach them, Burgoyne's subordinates advised retreat; a reconnaissance in force on October 7 was repulsed by Gates at the Battle of Bemis Heights, forcing them back into Saratoga with heavy losses. By October 11, all hope of escape had vanished; persistent rain reduced the camp to a "squalid hell" of mud and starving cattle, supplies were dangerously low and many of the wounded in agony. Burgoyne capitulated on October 17; around 6,222 soldiers, including German forces commanded by General Friedrich Adolf Riedesel, surrendered their arms before being taken to Boston, where they were to be transported to England. + +After securing additional supplies, Howe made another attempt on Philadelphia by landing his troops in Chesapeake Bay on August 24. He now compounded failure to support Burgoyne by missing repeated opportunities to destroy his opponent, defeating Washington at the Battle of Brandywine on September 11, then allowing him to withdraw in good order. After dispersing an American detachment at Paoli on September 20, Cornwallis occupied Philadelphia on September 26, with the main force of 9,000 under Howe based just to the north at Germantown. Washington attacked them on October 4, but was repulsed. + +To prevent Howe's forces in Philadelphia being resupplied by sea, the Patriots erected Fort Mifflin and nearby Fort Mercer on the east and west banks of the Delaware respectively, and placed obstacles in the river south of the city. This was supported by a small flotilla of Continental Navy ships on the Delaware, supplemented by the Pennsylvania State Navy, commanded by John Hazelwood. An attempt by the Royal Navy to take the forts in the October 20 to 22 Battle of Red Bank failed; a second attack captured Fort Mifflin on November 16, while Fort Mercer was abandoned two days later when Cornwallis breached the walls. His supply lines secured, Howe tried to tempt Washington into giving battle, but after inconclusive skirmishing at the Battle of White Marsh from December 5 to 8, he withdrew to Philadelphia for the winter. + +On December 19, the Americans followed suit and entered winter quarters at Valley Forge; while Washington's domestic opponents contrasted his lack of battlefield success with Gates' victory at Saratoga, foreign observers such as Frederick the Great were equally impressed with Germantown, which demonstrated resilience and determination. Over the winter, poor conditions, supply problems and low morale resulted in 2,000 deaths, with another 3,000 unfit for duty due to lack of shoes. However, Baron Friedrich Wilhelm von Steuben took the opportunity to introduce Prussian Army drill and infantry tactics to the entire Continental Army; he did this by training "model companies" in each regiment, who then instructed their home units. Despite Valley Forge being only twenty miles away, Howe made no effort to attack their camp, an action some critics argue could have ended the war. + +Foreign intervention + +Like his predecessors, French foreign minister Vergennes considered the 1763 Peace a national humiliation and viewed the war as an opportunity to weaken Britain. He initially avoided open conflict, but allowed American ships to take on cargoes in French ports, a technical violation of neutrality. Although public opinion favored the American cause, Finance Minister Turgot argued they did not need French help to gain independence, and war was too expensive. Instead, Vergennes persuaded Louis XVI to secretly fund a government front company to purchase munitions for the Patriots, carried in neutral Dutch ships and imported through Sint Eustatius in the Caribbean. + +Many Americans opposed a French alliance, fearing to "exchange one tyranny for another", but this changed after a series of military setbacks in early 1776. As France had nothing to gain from the colonies reconciling with Britain, Congress had three choices; making peace on British terms, continuing the struggle on their own, or proclaiming independence, guaranteed by France. Although the Declaration of Independence in July 1776 had wide public support, Adams was among those reluctant to pay the price of an alliance with France, and over 20% of Congressmen voted against it. Congress agreed to the treaty with reluctance and as the war moved in their favor increasingly lost interest in it. + +Silas Deane was sent to Paris to begin negotiations with Vergennes, whose key objectives were replacing Britain as the United States' primary commercial and military partner while securing the French West Indies from American expansion. These islands were extremely valuable; in 1772, the value of sugar and coffee produced by Saint-Domingue on its own exceeded that of all American exports combined. Talks progressed slowly until October 1777, when British defeat at Saratoga and their apparent willingness to negotiate peace convinced Vergennes only a permanent alliance could prevent the "disaster" of Anglo-American rapprochement. Assurances of formal French support allowed Congress to reject the Carlisle Peace Commission and insist on nothing short of complete independence. + +On February 6, 1778, France and the United States signed the Treaty of Amity and Commerce regulating trade between the two countries, followed by a defensive military alliance against Britain, the Treaty of Alliance. In return for French guarantees of American independence, Congress undertook to defend their interests in the West Indies, while both sides agreed not to make a separate peace; conflict over these provisions would lead to the 1798 to 1800 Quasi-War. Charles III of Spain was invited to join on the same terms but refused, largely due to concerns over the impact of the Revolution on Spanish colonies in the Americas. Spain had complained on multiple occasions about encroachment by American settlers into Louisiana, a problem that could only get worse once the United States replaced Britain. + +Although Spain ultimately made important contributions to American success, in the Treaty of Aranjuez (1779), Charles agreed only to support France's war with Britain outside America, in return for help in recovering Gibraltar, Menorca and Spanish Florida. The terms were confidential since several conflicted with American aims; for example, the French claimed exclusive control of the Newfoundland cod fisheries, a non-negotiable for colonies like Massachusetts. One less well-known impact of this agreement was the abiding American distrust of 'foreign entanglements'; the US would not sign another treaty with France until their NATO agreement of 1949. This was because the US had agreed not to make peace without France, while Aranjuez committed France to keep fighting until Spain recovered Gibraltar, effectively making it a condition of US independence without the knowledge of Congress. + +To encourage French participation in the struggle for independence, the US representative in Paris, Silas Deane promised promotion and command positions to any French officer who joined the Continental Army. Such as Gilbert du Motier, Marquis de Lafayette, whom Congress via Dean appointed a major General, on July 31, 1777. + +When the war started, Britain tried to borrow the Dutch-based Scots Brigade for service in America, but pro-Patriot sentiment led the States General to refuse. Although the Republic was no longer a major power, prior to 1774 they still dominated the European carrying trade, and Dutch merchants made large profits shipping French-supplied munitions to the Patriots. This ended when Britain declared war in December 1780, a conflict that proved disastrous to the Dutch economy. The Dutch were also excluded from the First League of Armed Neutrality, formed by Russia, Sweden and Denmark in March 1780 to protect neutral shipping from being stopped and searched for contraband by Britain and France. + +The British government failed to take into account the strength of the American merchant marine and support from European countries, which allowed the colonies to import munitions and continue trading with relative impunity. While well aware of this, the North administration delayed placing the Royal Navy on a war footing for cost reasons; this prevented the institution of an effective blockade and restricted them to ineffectual diplomatic protests. Traditional British policy was to employ European land-based allies to divert the opposition, a role filled by Prussia in the Seven Years' War; in 1778, they were diplomatically isolated and faced war on multiple fronts. + +Meanwhile, George III had given up on subduing America while Britain had a European war to fight. He did not welcome war with France, but he believed the British victories over France in the Seven Years' War as a reason to believe in ultimate victory over France. Britain could not find a powerful ally among the Great Powers to engage France on the European continent. Britain subsequently changed its focus into the Caribbean theater, and diverted major military resources away from America. + +Vergennes's colleague stated, "For her honour, France had to seize this opportunity to rise from her degradation ... If she neglected it, if fear overcame duty, she would add debasement to humiliation, and become an object of contempt to her own century and to all future peoples". + +Stalemate in the North + +At the end of 1777, Howe resigned and was replaced by Sir Henry Clinton on May 24, 1778; with French entry into the war, he was ordered to consolidate his forces in New York. On June 18, the British departed Philadelphia with the reinvigorated Americans in pursuit; the Battle of Monmouth on June 28 was inconclusive but boosted Patriot morale. Washington had rallied Charles Lee's broken regiments, the Continentals repulsed British bayonet charges, the British rear guard lost perhaps 50 per-cent more casualties, and the Americans held the field at the end of the day. That midnight, the newly installed Clinton continued his retreat to New York. + +A French naval force under Admiral Charles Henri Hector d'Estaing was sent to assist Washington; deciding New York was too formidable a target, in August they launched a combined attack on Newport, with General John Sullivan commanding land forces. The resulting Battle of Rhode Island was indecisive; badly damaged by a storm, the French withdrew to avoid putting their ships at risk. Further activity was limited to British raids on Chestnut Neck and Little Egg Harbor in October. + +In July 1779, the Americans captured British positions at Stony Point and Paulus Hook. Clinton unsuccessfully tried to tempt Washington into a decisive engagement by sending General William Tryon to raid Connecticut. In July, a large American naval operation, the Penobscot Expedition, attempted to retake Maine, then part of Massachusetts, but was defeated. Persistent Iroquois raids along the border with Quebec led to the punitive Sullivan Expedition in April 1779, destroying many settlements but failing to stop them. + +During the winter of 1779–1780, the Continental Army suffered greater hardships than at Valley Forge. Morale was poor, public support fell away in the long war, the Continental dollar was virtually worthless, the army was plagued with supply problems, desertion was common, and mutinies occurred in the Pennsylvania Line and New Jersey Line regiments over the conditions in early 1780. + +In June 1780, Clinton sent 6,000 men under Wilhelm von Knyphausen to retake New Jersey, but they were halted by local militia at the Battle of Connecticut Farms; although the Americans withdrew, Knyphausen felt he was not strong enough to engage Washington's main force and retreated. A second attempt two weeks later ended in a British defeat at the Battle of Springfield, effectively ending their ambitions in New Jersey. In July, Washington appointed Benedict Arnold commander of West Point; his attempt to betray the fort to the British failed due to incompetent planning, and the plot was revealed when his British contact John André was captured and later executed. Arnold escaped to New York and switched sides, an action justified in a pamphlet addressed "To the Inhabitants of America"; the Patriots condemned his betrayal, while he found himself almost as unpopular with the British. + +War in the South + +The Southern Strategy was developed by Lord Germain, based on input from London-based Loyalists, including Joseph Galloway. They argued that it made no sense to fight the Patriots in the north where they were strongest, while the New England economy was reliant on trade with Britain, regardless of who governed it. On the other hand, duties on tobacco made the South far more profitable for Britain, while local support meant securing it required small numbers of regular troops. Victory would leave a truncated United States facing British possessions in the south, Canada to the north, and Ohio on their western border; with the Atlantic seaboard controlled by the Royal Navy, Congress would be forced to agree to terms. However, assumptions about the level of Loyalist support proved wildly optimistic. + +Germain accordingly ordered Augustine Prévost, the British commander in East Florida, to advance into Georgia in December 1778. Lieutenant-Colonel Archibald Campbell, an experienced officer taken prisoner earlier in the war before being exchanged for Ethan Allen, captured Savannah on December 29, 1778. He recruited a Loyalist militia of nearly 1,100, many of whom allegedly joined only after Campbell threatened to confiscate their property. Poor motivation and training made them unreliable troops, as demonstrated in their defeat by Patriot militia at the Battle of Kettle Creek on February 14, 1779, although this was offset by British victory at Brier Creek on March 3. + +In June 1779, Prévost launched an abortive assault on Charleston, before retreating to Savannah, an operation notorious for widespread looting by British troops that enraged both Loyalists and Patriots. In October, a joint French and American operation under Admiral d'Estaing and General Benjamin Lincoln failed to recapture Savannah. Prévost was replaced by Lord Cornwallis, who assumed responsibility for Germain's strategy; he soon realized estimates of Loyalist support were considerably over-stated, and he needed far larger numbers of regular forces. + +Reinforced by Clinton, Cornwallis' troops captured Charleston in May 1780, inflicting the most serious Patriot defeat of the war; over 5,000 prisoners were taken and the Continental Army in the south effectively destroyed. On May 29, Lieutenant-Colonel Banastre Tarleton's mainly Loyalist force routed a Continental Army force nearly three times its size under the command of Colonel Abraham Buford at the Battle of Waxhaws. The battle is controversial for allegations of a massacre, which were later used as a recruiting tool by the Patriots. + +Clinton returned to New York, leaving Cornwallis to oversee the south; despite their success, the two men left barely on speaking terms, with dire consequences for the future conduct of the war. The Southern strategy depended on local support, but this was undermined by a series of coercive measures. Previously, captured Patriots were sent home after swearing not to take up arms against the king; they were now required to fight their former comrades, while the confiscation of Patriot-owned plantations led formerly neutral "grandees" to side with them. Skirmishes at Williamson's Plantation, Cedar Springs, Rocky Mount, and Hanging Rock signaled widespread resistance to the new oaths throughout South Carolina. + +In July 1780, Congress appointed General Horatio Gates commander in the south; he was defeated at the Battle of Camden on August 16, leaving Cornwallis free to enter North Carolina. Despite battlefield success, the British could not control the countryside and Patriot attacks continued; before moving north, Cornwallis sent Loyalist militia under Major Patrick Ferguson to cover his left flank, leaving their forces too far apart to provide mutual support. In early October, Ferguson was defeated at the Battle of Kings Mountain, dispersing organized Loyalist resistance in the region. Despite this, Cornwallis continued into North Carolina hoping for Loyalist support, while Washington replaced Gates with General Nathanael Greene in December 1780. + +Greene divided his army, leading his main force southeast pursued by Cornwallis; a detachment was sent southwest under Daniel Morgan, who defeated Tarleton's British Legion at Cowpens on January 17, 1781, nearly eliminating it as a fighting force. The Patriots now held the initiative in the south, with the exception of a raid on Richmond led by Benedict Arnold in January 1781. Greene led Cornwallis on a series of countermarches around North Carolina; by early March, the British were exhausted and short of supplies and Greene felt strong enough to fight the Battle of Guilford Court House on March 15. Although victorious, Cornwallis suffered heavy casualties and retreated to Wilmington, North Carolina seeking supplies and reinforcements. + +The Patriots now controlled most of the Carolinas and Georgia outside the coastal areas; after a minor reversal at the Battle of Hobkirk's Hill, they recaptured Fort Watson and Fort Motte on April 15. On June 6, Brigadier General Andrew Pickens captured Augusta, leaving the British in Georgia confined to Charleston and Savannah. The assumption Loyalists would do most of the fighting left the British short of troops and battlefield victories came at the cost of losses they could not replace. Despite halting Greene's advance at the Battle of Eutaw Springs on September 8, Cornwallis withdrew to Charleston with little to show for his campaign. + +Western campaign + +From the beginning of the war, Bernardo de Gálvez, the Governor of Spanish Louisiana, allowed the Americans to import supplies and munitions into New Orleans, then ship them to Pittsburgh. This provided an alternative transportation route for the Continental Army, bypassing the British blockade of the Atlantic Coast. + +The trade was organized by Oliver Pollock, a successful merchant in Havana and New Orleans, who was appointed U.S. commercial agent. It also helped support the American campaign in the west; in the 1778 Illinois campaign, militia under General George Rogers Clark. + +In February 1778, an expedition of militia to destroy British military supplies in settlements along the Cuyahoga River was halted by adverse weather. Later in the year, a second campaign was undertaken to seize the Illinois Country from the British. Virginia militia, Canadien settlers, and Indian allies commanded by Colonel George Rogers Clark captured Kaskaskia on July 4 and then secured Vincennes, though Vincennes was recaptured by Quebec Governor Henry Hamilton. In early 1779, the Virginians counter-attacked in the siege of Fort Vincennes and took Hamilton prisoner. Clark secured western British Quebec as the American Northwest Territory in the Treaty of Paris brought the Revolutionary War to an end. + +When Spain joined France's war against Britain in the Anglo-French War in 1779, their treaty specifically excluded Spanish military action in North America. Later that year, however, Gálvez initiated offensive operations against British outposts. First, he cleared British garrisons in Baton Rouge, Louisiana, Fort Bute, and Natchez, Mississippi, and captured five forts. In doing so, Gálvez opened navigation on the Mississippi River north to the American settlement in Pittsburgh. + +On May 25, 1780, British Colonel Henry Bird invaded Kentucky as part of a wider operation to clear American resistance from Quebec to the Gulf Coast. Their Pensacola advance on New Orleans was repelled by Spanish Governor Gálvez's offensive on Mobile. Simultaneous British attacks were repulsed on St. Louis by the Spanish Lieutenant Governor de Leyba, and on the Virginia County courthouse in Cahokia, Illinois by Lieutenant Colonel Clark. The British initiative under Bird from Detroit was ended at the rumored approach of Clark. The scale of violence in the Licking River Valley, was extreme "even for frontier standards." It led to English and German settlements, who joined Clark's militia when the British and their hired German soldiers withdrew to the Great Lakes. The Americans responded with a major offensive along the Mad River in August which met with some success in the Battle of Piqua but did not end Indian raids. + +French soldier Augustin de La Balme led a Canadian militia in an attempt to capture Detroit, but they dispersed when Miami natives led by Little Turtle attacked the encamped settlers on November 5. The war in the west stalemated with the British garrison sitting in Detroit and the Virginians expanding westward settlements north of the Ohio River in the face of British-allied Indian resistance. + +In 1781, Galvez and Pollock campaigned east along the Gulf Coast to secure West Florida, including British-held Mobile and Pensacola. The Spanish operations impaired the British supply of armaments to British Indian allies, which effectively suspended a military alliance to attack settlers between the Mississippi River and the Appalachian Mountains. + +In 1782, large scale retaliations between settlers and Native Americans in the region included the Gnadenhutten massacre and the Crawford expedition. The 1782 Battle of Blue Licks was one of the last major engagements of the American Revolutionary War. News of the treaty between Great Britain and the United States arrived late that year. By this time, about 7% of Kentucky settlers had been killed in battles against Native Americans, contrasted with 1% of the population killed in the Thirteen Colonies. Lingering resentments led to continued fighting in the west after the war officially ended. + +British defeat + +Clinton spent most of 1781 based in New York City; he failed to construct a coherent operational strategy, partly due to his difficult relationship with Admiral Marriot Arbuthnot. In Charleston, Cornwallis independently developed an aggressive plan for a campaign in Virginia, which he hoped would isolate Greene's army in the Carolinas and cause the collapse of Patriot resistance in the South. This strategy was approved by Lord Germain in London, but neither of them informed Clinton. + +Washington and Rochambeau, meanwhile, discussed their options. Washington wanted to attack the British in New York, and Rochambeau wanted to attack them in Virginia, where Cornwallis' forces were less established and arguably easier to defeat. Washington eventually gave way, and Lafayette took a combined Franco-American force into Virginia, but Clinton misinterpreted his movements as preparations for an attack on New York. Concerned by a perceived threat to his positions in New York, he instructed Cornwallis to establish a fortified sea base, where the Royal Navy could evacuate British troops to help defend New York. + +When Lafayette entered Virginia, Cornwallis complied with Clinton's orders and withdrew to Yorktown, where he constructed strong defenses and awaited evacuation. An agreement by the Spanish Navy to defend the French West Indies allowed Admiral de Grasse to relocate to the Atlantic seaboard, a move Arbuthnot did not anticipate. This provided Lafayette naval support, while the failure of previous combined operations at Newport and Savannah meant their coordination was planned more carefully. Despite repeated urging from his subordinates, Cornwallis made no attempt to engage Lafayette before he could establish siege lines. Expecting to be withdrawn within a few days, he also abandoned the outer defenses, which were promptly occupied by the besiegers and hastened British defeat. + +On August 31, a Royal Navy fleet under Thomas Graves left New York for Yorktown. After landing troops and munitions for the besiegers on August 30, de Grasse remained in Chesapeake Bay and intercepted him on September 5; although the Battle of the Chesapeake was indecisive in terms of losses, Graves was forced to retreat, leaving Cornwallis isolated. An attempted breakout over York River at Gloucester Point failed due to bad weather. Under heavy bombardment with dwindling supplies, Cornwallis felt his situation was hopeless and on October 16 sent emissaries to General Washington to negotiate their surrender; after twelve hours of negotiations, the terms of surrender were finalized the following day. Responsibility for defeat was the subject of fierce public debate between Cornwallis, Clinton, and Germain. Despite criticism from his junior officers, Cornwallis retained the confidence of his peers and later held a series of senior government positions. Clinton ultimately took most of the blame and spent the rest of his life in relative obscurity. + +Subsequent to Yorktown, American forces were assigned to supervise the armistice between Washington and Clinton made to facilitate British departure following the January 1782 law of Parliament forbidding any further British offensive action in North America. British-American negotiations in Paris led to signed preliminary agreements in November 1782, which acknowledged U.S. independence. The enacted Congressional war objective, a British withdrawal from North America and cession of these regions to the U.S., was completed in stages in East Coast cities. + +In the U.S. South, Generals Greene and Wayne loosely invested the withdrawing British at Savannah and Charleston, where they observed the British remove their troops from Charleston on December 14, 1782. Loyalist provincial militias of whites and free blacks and Loyalists with slaves were transported to Nova Scotia and the British West Indies. Native American allies of the British and some freed blacks were left to escape unaided through the American lines. + +Washington moved his army to New Windsor on the Hudson River about sixty miles north of New York City, and there the substance of the Continental Army was furloughed home with officers at half pay until the Treaty of Paris formally ended the war on September 3, 1783. At that time, Congress decommissioned the regiments of Washington's Continental Army and began issuing land grants to veterans in the Northwest Territories for their war service. The last British occupation of New York City ended on November 25, 1783, with the departure of Clinton's replacement, General Sir Guy Carleton. + +Strategy and commanders + +To win their insurrection, Washington and the Continental Army needed to outlast the British will to continue the fight. To restore their British America empire, the British had to defeat the Continental Army in the early months, and compel Second Continental Congress in Philadelphia to dissolve and retract its claim to self-governance. Historian Terry M. Mays of The Citadel identifies three separate types of warfare during the Revolutionary War. The first was a colonial conflict in which objections to imperial trade regulation were as significant as taxation policy. The second was a civil war with all Thirteen Colonies split between American patriots, American loyalists, and those who preferred to remain neutral in the revolution and war. Particularly in the south, many battles were fought between Patriots and Loyalists with no British involvement, leading to divisions that continued after independence was achieved. + +The third element was a global war between France, Spain, the Dutch Republic, and Britain, with America serving as one of several different war theaters. After entering the Revolutionary War in 1778, France provided the Americans money, weapons, soldiers, and naval assistance, while French troops fought under U.S. command in North America. While Spain did not formally join the war in America, they provided access to the Mississippi River and captured British possessions on the Gulf of Mexico that denied bases to the Royal Navy, retook Menorca and besieged Gibraltar in Europe. + +Although the Dutch Republic was no longer a major power prior to 1774, they still dominated the European carrying trade, and Dutch merchants made large profits by shipping French-supplied munitions to the Patriots. This ended when Britain declared war in December 1780, and the conflict proved disastrous to Dutch economy. The Dutch were also excluded from the First League of Armed Neutrality formed by Russia, Sweden, and Denmark in March 1780 that protected neutral ships from being stopped and searched for contraband by Britain and France. While of limited effect, these interventions forced the British to divert men and resources away from North America. + +American strategy +The Second Continental Congress, meeting in Philadelphia, stood to benefit if the American Revolution evolved into a protracted war. Their thirteen colonial state populations were largely prosperous and depended on local production for food and supplies rather than on imports from Britain, which took six to twelve weeks to arrive by cross-Atlantic shipping. The thirteen colonies were spread across most of North American Atlantic seaboard, stretching 1,000 miles. Most colonial farms were remote from the seaports, and control of four or five major ports did not give Britain control over American inland areas. Each state had established internal distribution systems. + +Each of the thirteen colonies also had a long-established system of local militia, which were combat-tested in support of British regulars thirteen years before to secure an expanded British Empire. Together, these militias denied France's claims to North America west of the Mississippi River in the French and Indian War. The thirteen colonial state legislatures independently funded and controlled their local militias. In the American Revolution, they trained and provided Continental Line regiments to the regular army, each with their own state officer corps. Motivation was also a major asset: each colonial capital had its own newspapers and printers, and the Patriots enjoyed more popular support than the Loyalists. Britain hoped that the Loyalists would do much of the fighting, but found that the Loyalists did not engage as significantly as they had hoped. + +Continental Army + +When the Revolutionary War began, the Second Continental Congress lacked a professional army or navy, but each colony maintained local militias. Militiamen were lightly armed, had little training, and usually did not have uniforms. Their units served for only a few weeks or months at a time and lacked the training and discipline of more experienced soldiers. Local county militias were reluctant to travel far from home and they were unavailable for extended operations. To compensate for this, the Continental Congress established a regular force known as the Continental Army on June 14, 1775, which proved to be the origin of the modern United States Army, and appointed Washington as its commander-in-chief. However, it suffered significantly from the lack of an effective training program and from largely inexperienced officers and sergeants, offset by a few senior officers. + +Each state legislature appointed officers for both county and state militias and their regimental Continental line officers; although Washington was required to accept Congressional appointments, he was still permitted to choose and command his own generals, such as Nathanael Greene; his chief of artillery, Henry Knox; and Alexander Hamilton, the chief of staff. One of Washington's most successful general officer recruits was Baron Friedrich Wilhelm von Steuben, a veteran of the Prussian general staff who wrote the Revolutionary War Drill Manual. The development of the Continental Army was always a work in progress and Washington used both his regulars and state militias throughout the war; when properly employed, the combination allowed them to overwhelm smaller British forces, as they did in battles at Concord, Boston, Bennington, and Saratoga. Both sides used partisan warfare, but the state militias effectively suppressed Loyalist activity when British regulars were not in the area. + +Washington designed the overall military strategy of the Revolutionary War in cooperation with Congress, established the principle of civilian supremacy in military affairs, personally recruited his senior officer corps, and kept the states focused on a common goal. For the first three years until after fall of Philadelphia and the six-month encampment at Valley Forge, the Continental Army was largely supplemented by local state militias. Washington initially employed the inexperienced officers and untrained troops in Fabian strategies rather than risk frontal assaults against Britain's professional soldiers and officers. Over the course of the entire war, Washington lost more battles than he won, but he never surrendered his troops and maintained a fighting force in the face of British field armies and never gave up fighting for the American cause. + +By prevailing European standards, the armies in America were relatively small, limited by lack of supplies and logistics. The British were constrained by the logistical difficulty of transporting troops across the Atlantic and their dependence on local supplies. Throughout the war, Washington never directly commanded more than 17,000 men, and the combined Franco-American army in the decisive American victory at Yorktown was only about 19,000. At the beginning of 1776, Patriot forces consisted of 20,000 men with two-thirds of them in the Continental Army and the other third in the various state militias. About 250,000 American men served as regulars or as militia for the revolutionary cause over eight years during wartime, but there were never more than 90,000 men under arms at any time. + +On the whole, American officers never equaled their British opponents in tactics and maneuvers, and they lost most of the pitched battles. The great successes at Boston (1776), Saratoga (1777), and Yorktown (1781) were won by trapping the British far from base with a greater number of troops. After 1778, however, Washington's army was transformed into a more disciplined and effective force, mostly as a product of Baron von Steuben's military training. Immediately after the Continental Army emerged from Valley Forge in June 1778, it proved its ability to match the military capabilities of the British at the Battle of Monmouth, including a black Rhode Island regiment fending off a British bayonet attack and then counter charging the British for the first time as part of Washington's army. After the Battle of Monmouth, Washington came to realize that saving entire towns was not necessary, but preserving his army and keeping the revolutionary spirit alive was more important. Washington informed Henry Laurens, then president of the Second Continental Congress, "that the possession of our towns, while we have an army in the field, will avail them little." + +Although the Continental Congress was responsible for the war effort and provided supplies to the troops, Washington took it upon himself to pressure Congress and the state legislatures to provide the essentials of war; there was never nearly enough. Congress evolved in its committee oversight and established the Board of War, which included members of the military. Because the Board of War was also a committee ensnared with its own internal procedures, Congress also created the post of Secretary of War, appointing Major General Benjamin Lincoln to the position in February 1781. Washington worked closely with Lincoln to coordinate civilian and military authorities and took charge of training and supplying the army. + +Continental Navy + + +During the first summer of the war, Washington began outfitting schooners and other small seagoing vessels to prey on ships supplying the British in Boston. The Second Continental Congress established the Continental Navy on October 13, 1775, and appointed Esek Hopkins as its first commander; for most of the war, the Continental Navy included only a handful of small frigates and sloops, supported by numerous privateers. On November 10, 1775, Congress authorized the creation of the Continental Marines, which ultimately evolved into, and was named, the United States Marine Corps. + +John Paul Jones became the first American naval hero when he captured HMS Drake on April 24, 1778, the first victory for any American military vessel in British waters. The last such victory was by the frigate USS Alliance, commanded by Captain John Barry. On March 10, 1783, the Alliance outgunned HMS Sybil in a 45-minute duel while escorting Spanish gold from Havana to the Congress in Philadelphia. After Yorktown, all US Navy ships were sold or given away; it was the first time in America's history that it had no fighting forces on the high seas. + +Congress primarily commissioned privateers to reduce costs and to take advantage of the large proportion of colonial sailors found in the British Empire. In total, they included 1,700 ships that successfully captured 2,283 enemy ships to damage the British effort and to enrich themselves with the proceeds from the sale of cargo and the ship itself. About 55,000 sailors served aboard American privateers during the war. + +France + +At the beginning of the Revolutionary War, the Americans had no major international allies, since most nation-states watched and waited to see how developments unfolded in the conflict in British America. Over time, the Continental Army established its military credibility, defeating or holding their own against British regulars and their hired Hessians known to all European great powers. Battles such as the Battle of Bennington, the Battles of Saratoga, and even defeats such as the Battle of Germantown, proved decisive in gaining the attention and support of powerful European nations, including France, Spain, and the Dutch Republic; the Dutch, impressed by these American victories and conflicts, moved from covertly supplying the Americans with weapons and supplies to overtly supporting them. + +The decisive American victory at Saratoga convinced France, which was already a long-time rival of Britain, to offer the Americans the Treaty of Amity and Commerce. The two nations also agreed to a defensive Treaty of Alliance to protect their trade and also guaranteed American independence from Britain. To engage the United States as a French ally militarily, the treaty was conditioned on Britain initiating a war on France to stop it from trading with the U.S. Spain and the Dutch Republic were invited to join by both France and the United States in the treaty, but neither was responsive to the request. + +On June 13, 1778, France declared war on Great Britain, and it invoked the French military alliance with the U.S., which ensured additional U.S. private support for French possessions in the Caribbean. Washington worked closely with the soldiers and navy that France would send to America, primarily through Lafayette on his staff. French assistance made critical contributions required to defeat General Charles Cornwallis at Yorktown in 1781. + +British strategy + +The British military had considerable experience of fighting in North America, most recently during the Seven Years' War which forced France to give up New France in 1763. However, in previous conflicts they benefited from local logistics, as well as support from the colonial militia, which was not available in the American Revolutionary War. Reinforcements had to come from Europe, and maintaining large armies over such distances was extremely complex; ships could take three months to cross the Atlantic, and orders from London were often outdated by the time they arrived. + +Prior to the conflict, the colonies were largely autonomous economic and political entities, with no centralized area of ultimate strategic importance. This meant that, unlike Europe where the fall of a capital city often ended wars, that in America continued even after the loss of major settlements such as Philadelphia, the seat of Congress, New York, and Charleston. British power was reliant on the Royal Navy, whose dominance allowed them to resupply their own expeditionary forces while preventing access to enemy ports. However, the majority of the American population was agrarian, rather than urban; supported by the French navy and blockade runners based in the Dutch Caribbean, their economy was able to survive. + +The geographical size of the colonies and limited manpower meant the British could not simultaneously conduct military operations and occupy territory without local support. Debate persists over whether their defeat was inevitable; one British statesman described it as "like trying to conquer a map". While Ferling argues Patriot victory was nothing short of a miracle, Ellis suggests the odds always favored the Americans, especially after Howe squandered the chance of a decisive British success in 1776, an "opportunity that would never come again". The US military history speculates the additional commitment of 10,000 fresh troops in 1780 would have placed British victory "within the realm of possibility". + +British Army + +The expulsion of France from North America in 1763 led to a drastic reduction in British troop levels in the colonies; in 1775, there were only 8,500 regular soldiers among a civilian population of 2.8 million. The bulk of military resources in the Americas were focused on defending sugar islands in the Caribbean; Jamaica alone generated more revenue than all thirteen American colonies combined. With the end of the Seven Years' War, the permanent army in Britain was also cut back, which resulted in administrative difficulties when the war began a decade later. + +Over the course of the war, there were four separate British commanders-in-chief. The first was Thomas Gage, appointed in 1763, whose initial focus was establishing British rule in former French areas of Canada. Rightly or wrongly, many in London blamed the revolt on his failure to take firm action earlier, and he was relieved after the heavy losses incurred at the Battle of Bunker Hill in Charlestown, Massachusetts. His replacement was Sir William Howe, a member of the Whig faction in Parliament who opposed the policy of coercion advocated by Lord North; Cornwallis, who later surrendered at Yorktown, was one of many senior officers who initially refused to serve in North America. + +The 1775 campaign showed the British overestimated the capabilities of their own troops and underestimated the colonial militia, requiring a reassessment of tactics and strategy. However, it allowed the Patriots to take the initiative and British authorities rapidly lost control over every colony. Howe's responsibility is still debated; despite receiving large numbers of reinforcements, Bunker Hill seems to have permanently affected his self-confidence and lack of tactical flexibility meant he often failed to follow up opportunities. Many of his decisions were attributed to supply problems, such as the delay in launching the New York campaign and failure to pursue Washington's beaten army. Having lost the confidence of his subordinates, he was recalled after Burgoyne surrendered at Saratoga. + +Following the failure of the Carlisle Commission, British policy changed from treating the Patriots as subjects who needed to be reconciled to enemies who had to be defeated. In 1778, Howe was replaced by Sir Henry Clinton, appointed instead of Carleton who was considered overly cautious. Regarded as an expert on tactics and strategy, like his predecessors Clinton was handicapped by chronic supply issues. As a result, he was largely inactive in 1779 and much of 1780; in October 1780, he warned Germain of "fatal consequences" if matters did not improve. + +In addition, Clinton's strategy was compromised by conflict with political superiors in London and his colleagues in North America, especially Admiral Mariot Arbuthnot, replaced in early 1781 by Rodney. He was neither notified nor consulted when Germain approved Cornwallis' invasion of the south in 1781 and delayed sending him reinforcements believing the bulk of Washington's army was still outside New York City. After the surrender at Yorktown, Clinton was relieved by Carleton, whose major task was to oversee the evacuation of Loyalists and British troops from Savannah, Charleston, and New York City. + +German troops + +During the 18th century, states commonly hired foreign soldiers, including Britain. During the Seven Years' War, foreign soldiers comprised 10% of the British army and their use caused little debate. When it became clear additional troops were needed to suppress the revolt in America, it was decided to employ professional German soldiers. There were several reasons for this, including public sympathy for the Patriot cause, an historical reluctance to expand the British army and the time needed to recruit and train new regiments. An alternate source was readily available in the Holy Roman Empire, where many smaller states had a long tradition of renting their armies to the highest bidder. The most important was Hesse-Kassel, known as "the Mercenary State". + +The first supply agreements were signed by the North administration in late 1775; over the next decade, more than 40,000 Germans fought in North America, Gibraltar, South Africa and India, of whom 30,000 served in the American War. Often generically referred to as "Hessians", they included men from many other states, including Hanover and Brunswick. Sir Henry Clinton recommended recruiting Russian troops whom he rated very highly, having seen them in action against the Ottomans; however, negotiations with Catherine the Great made little progress. + +Unlike previous wars their use led to intense political debate in Britain, France, and even Germany, where Frederick the Great refused to provide passage through his territories for troops hired for the American war. In March 1776, the agreements were challenged in Parliament by Whigs who objected to "coercion" in general, and the use of foreign soldiers to subdue "British subjects". The debates were covered in detail by American newspapers, which reprinted key speeches and in May 1776 they received copies of the treaties themselves. Provided by British sympathizers, these were smuggled into North America from London by George Merchant, a recently released American prisoner. + +The prospect of foreign German soldiers being used in the colonies bolstered support for independence, more so than taxation and other acts combined; the King was accused of declaring war on his own subjects, leading to the idea there were now two separate governments. By apparently showing Britain was determined to go to war, it made hopes of reconciliation seem naive and hopeless, while the employment of what was regarded as "foreign mercenaries" became one of the charges levelled against George III in the Declaration of Independence. The Hessian reputation within Germany for brutality also increased support for the Patriot cause among German-American immigrants. + +The presence of over 150,000 German Americans meant both sides felt the German soldiers might be persuaded to desert; one reason Clinton suggested employing Russians was that he felt they were less likely to defect. When the first German troops arrived on Staten Island in August 1776, Congress approved the printing of handbills, promising land and citizenship to any willing to join the Patriot cause. The British launched a counter-campaign claiming deserters could well be executed for meddling in a war that was not theirs. Desertion among the Germans occurred throughout the war, with the highest rate of desertion occurring during the time between the surrender at Yorktown and the Treaty of Paris. German regiments were central to the British war effort; of the estimated 30,000 sent to America, some 13,000 became casualties. + +Revolution as civil war + +Loyalists + +Wealthy Loyalists convinced the British government that most of the colonists were sympathetic toward the Crown; consequently, British military planners relied on recruiting Loyalists, but had trouble recruiting sufficient numbers as the Patriots had widespread support. Nevertheless, they continued to deceive themselves on their level of American support as late as 1780, a year before hostilities ended. + +Approximately 25,000 Loyalists fought for the British throughout the war. Although Loyalists constituted about twenty percent of the colonial population, they were concentrated in distinct communities. Many of them lived among large plantation owners in the Tidewater region and South Carolina who produced cash crops in tobacco and indigo comparable to global markets in Caribbean sugar. + +When the British began probing the backcountry in 1777–1778, they were faced with a major problem: any significant level of organized Loyalist activity required a continued presence of British regulars. The available manpower that the British had in America was insufficient to protect Loyalist territory and counter American offensives. The Loyalist militias in the South were constantly defeated by neighboring Patriot militia. The most critical combat between the two partisan militias was at the Battle of Kings Mountain; the Patriot victory irreversibly impaired any further Loyalist militia capability in the South. + +When the early war policy was administered by General William Howe, the Crown's need to maintain Loyalist support prevented it from using the traditional revolt suppression methods. The British cause suffered when their troops ransacked local homes during an aborted attack on Charleston in 1779 that enraged both Patriots and Loyalists. After Congress rejected the Carlisle Peace Commission in 1778 and Westminster turned to "hard war" during Clinton's command, neutral colonists in the Carolinas often allied with the Patriots whenever brutal combat broke out between Tories and Whigs. Conversely, Loyalists gained support when Patriots intimidated suspected Tories by destroying property or tarring and feathering. + +A Loyalist militia unit—the British Legion—provided some of the best troops in British service; it received a commission in the British Army. It was a mixed regiment of 250 dragoons and 200 infantry supported by batteries of flying artillery. It was commanded by Banastre Tarleton and gained a fearsome reputation in the colonies for "brutality and needless slaughter".In May 1779 the British Legion was one of five regiments that formed the American Establishment. + +Women + +Women played various roles during the Revolutionary War; they often accompanied their husbands when permitted to do so. For example, throughout the war Martha Washington was known to visit and provide aid to her husband George at various American camps, and Frederika Charlotte Riedesel documented the Saratoga campaign. Women often accompanied armies as camp followers to sell goods and perform necessary tasks in hospitals and camps. They were a necessary part of eighteenth-century armies, and numbered in the thousands during the war. + +Women also assumed military roles: aside from military tasks like treating the wounded or setting up camp, some dressed as men to directly support combat, fight, or act as spies on both sides of the Revolutionary War. Anna Maria Lane joined her husband in the Army and wore men's clothes by the time the Battle of Germantown happened. The Virginia General Assembly later cited her bravery: she fought while dressed as a man and "performed extraordinary military services, and received a severe wound at the battle of Germantown ... with the courage of a soldier". + +On April 26, 1777, Sybil Ludington is said to have ridden to alert militia forces of Putnam County, New York, and Danbury, Connecticut, to warn them of the British's approach; she has been called the "female Paul Revere". A report in The New England Quarterly says there is little evidence backing the story, and whether the ride occurred is questioned. A few others disguised themselves as men. Deborah Sampson fought until her gender was discovered and discharged as a result; Sally St. Clair was killed in action during the war. + +African Americans + +When war began, the population of the Thirteen Colonies included an estimated 500,000 slaves, predominantly used as labor on Southern plantations. In November 1775, Lord Dunmore, the royal governor of Virginia, issued a proclamation that promised freedom to any Patriot-owned slaves willing to bear arms. Although the announcement helped to fill a temporary manpower shortage, white Loyalist prejudice meant recruits were eventually redirected to non-combatant roles. The Loyalists' motive was to deprive Patriot planters of labor rather than to end slavery; Loyalist-owned slaves were returned. + +The 1779 Philipsburg Proclamation issued by Clinton extended the offer of freedom to Patriot-owned slaves throughout the colonies. It persuaded entire families to escape to British lines, many of which were employed on farms to grow food for the army by removing the requirement for military service. While Clinton organized the Black Pioneers, he also ensured fugitive slaves were returned to Loyalist owners with orders that they were not to be punished for their attempted escape. As the war progressed, service as regular soldiers in British units became increasingly common; black Loyalists formed two regiments of the Charleston garrison in 1783. + +Estimates of the numbers who served the British during the war vary from 25,000 to 50,000, excluding those who escaped during wartime. Thomas Jefferson estimated that Virginia may have lost 30,000 slaves in total escapes. In South Carolina, nearly 25,000 slaves (about 30 percent of the enslaved population) either fled, migrated, or died, which significantly disrupted the plantation economies both during and after the war. + +Black Patriots were barred from the Continental Army until Washington convinced Congress in January 1778 that there was no other way to replace losses from disease and desertion. The 1st Rhode Island Regiment formed in February included former slaves whose owners were compensated; however, only 140 of its 225 soldiers were black and recruitment stopped in June 1788. Ultimately, around 5,000 African-Americans served in the Continental Army and Navy in a variety of roles, while another 4,000 were employed in Patriot militia units, aboard privateers, or as teamsters, servants, and spies. After the war, a small minority received land grants or Congressional pensions in old age; many others were returned to their masters post-war despite earlier promises of freedom. + +As a Patriot victory became increasingly likely, the treatment of Black Loyalists became a point of contention; after the surrender of Yorktown in 1781, Washington insisted all escapees be returned but Cornwallis refused. In 1782 and 1783, around 8,000 to 10,000 freed blacks were evacuated by the British from Charleston, Savannah, and New York; some moved onto London, while 3,000 to 4,000 settled in Nova Scotia, where they founded settlements such as Birchtown. White Loyalists transported 15,000 enslaved blacks to Jamaica and the Bahamas. The free Black Loyalists who migrated to the British West Indies included regular soldiers from Dunmore's Ethiopian Regiment, and those from Charleston who helped garrison the Leeward Islands. + +Native Americans + +Most Native Americans east of the Mississippi River were affected by the war, and many tribes were divided over how to respond to the conflict. A few tribes were friendly with the colonists, but most Natives opposed the union of the Colonies as a potential threat to their territory. Approximately 13,000 Natives fought on the British side, with the largest group coming from the Iroquois tribes who deployed around 1,500 men. + +Early in July 1776, Cherokee allies of Britain attacked the short-lived Washington District of North Carolina. Their defeat splintered both Cherokee settlements and people, and was directly responsible for the rise of the Chickamauga Cherokee, who perpetuated the Cherokee–American wars against American settlers for decades after hostilities with Britain ended. + +Creek and Seminole allies of Britain fought against Americans in Georgia and South Carolina. In 1778, a force of 800 Creeks destroyed American settlements along the Broad River in Georgia. Creek warriors also joined Thomas Brown's raids into South Carolina and assisted Britain during the Siege of Savannah. Many Native Americans were involved in the fight between Britain and Spain on the Gulf Coast and along the British side of the Mississippi River. Thousands of Creeks, Chickasaws, and Choctaws fought in major battles such as the Battle of Fort Charlotte, the Battle of Mobile, and the Siege of Pensacola. + +The Iroquois Confederacy was shattered as a result of the American Revolutionary War, whatever side they took; the Seneca, Onondaga, and Cayuga tribes sided with the British; members of the Mohawks fought on both sides; and many Tuscarora and Oneida sided with the Americans. To retaliate against raids on American settlement by Loyalists and their Indian allies, the Continental Army dispatched the Sullivan Expedition on a punitive expedition throughout New York to debilitate the Iroquois tribes that had sided with the British. Mohawk leaders Joseph Louis Cook and Joseph Brant sided with the Americans and the British respectively, which further exacerbated the split. + +In the western theater of the American Revolutionary War, conflicts between settlers and Native Americans led to lingering distrust. In the 1783 Treaty of Paris, Great Britain ceded control of the disputed lands between the Great Lakes and the Ohio River, but the Indian inhabitants were not a part of the peace negotiations. Tribes in the Northwest Territory joined as the Western Confederacy and allied with the British to resist American settlement, and their conflict continued after the Revolutionary War as the Northwest Indian War. + +Britain's "American war" and peace + +Changing Prime Ministers + +Lord North, Prime Minister since 1770, delegated control of the war in North America to Lord George Germain and the Earl of Sandwich, who was head of the Royal Navy from 1771 to 1782. Defeat at Saratoga in 1777 made it clear the revolt would not be easily suppressed, especially after the Franco-American alliance of February 1778, and French declaration of war in June. With Spain also expected to join the conflict, the Royal Navy needed to prioritize either the war in America or in Europe; Germain advocated the former, Sandwich the latter. + +British negotiators now proposed a second peace settlement to Congress. The terms presented by the Carlisle Peace Commission included acceptance of the principle of self-government. Parliament would recognize Congress as the governing body, suspend any objectionable legislation, surrender its right to local colonial taxation, and discuss including American representatives in the House of Commons. In return, all property confiscated from Loyalists would be returned, British debts honored, and locally enforced martial law accepted. However, Congress demanded either immediate recognition of independence or the withdrawal of all British troops; they knew the commission were not authorized to accept these, bringing negotiations to a rapid end. + +When the commissioners returned to London in November 1778, they recommended a change in policy. Sir Henry Clinton, the new British Commander-in-Chief in America, was ordered to stop treating the rebels as enemies, rather than subjects whose loyalty might be regained. Those standing orders would be in effect for three years until Clinton was relieved. + +North initially backed the Southern strategy attempting to exploit divisions between the mercantile north and slave-owning south, but after the defeat of Yorktown, he was forced to accept the fact that this policy had failed. It was clear the war was lost, although the Royal Navy forced the French to relocate their fleet to the Caribbean in November 1781 and resumed a close blockade of American trade. The resulting economic damage and rising inflation meant the US was now eager to end the war, while France was unable to provide further loans; Congress could no longer pay its soldiers. + +On February 27, 1782, a Whig motion to end the offensive war in America was carried by 19 votes. North now resigned, obliging the king to invite Lord Rockingham to form a government; a consistent supporter of the Patriot cause, he made a commitment to US independence a condition of doing so. George III reluctantly accepted and the new government took office on March 27, 1782; however, Rockingham died unexpectedly on July 1, and was replaced by Lord Shelburne who acknowledged American independence. + +American Congress signs a peace + +When Lord Rockingham, the Whig leader and friend of the American cause was elevated to Prime Minister, Congress consolidated its diplomatic consuls in Europe into a peace delegation at Paris. All were experienced in Congressional leadership. The dean of the delegation was Benjamin Franklin of Pennsylvania. He had become a celebrity in the French Court, but he was also an Enlightenment scientist with influence in the courts of European great powers in Prussia, England's former ally, and Austria, a Catholic empire like Spain. Since the 1760s, Franklin had been an organizer of British American inter-colony cooperation, and then served as a colonial lobbyist to Parliament in London. John Adams of Massachusetts had been consul to the Dutch Republic and was a prominent early New England Patriot. John Jay of New York had been consul to Spain and was a past president of the Continental Congress. As consul to the Dutch Republic, Henry Laurens of South Carolina had secured a preliminary agreement for a trade agreement. He had been a successor to John Jay as president of Congress and with Franklin was a member of the American Philosophical Society. Although active in the preliminaries, he was not a signer of the conclusive treaty. + +The Whig negotiators for Lord Rockingham and his successor, Prime Minister Lord Shelburne, included long-time friend of Benjamin Franklin from his time in London, David Hartley and Richard Oswald, who had negotiated Laurens' release from the Tower of London. The Preliminary Peace signed on November 30 met four key Congressional demands: independence, territory up to the Mississippi, navigation rights into the Gulf of Mexico, and fishing rights in Newfoundland. + +British strategy was to strengthen the U.S. sufficiently to prevent France from regaining a foothold in North America, and they had little interest in these proposals. However, divisions between their opponents allowed them to negotiate separately with each to improve their overall position, starting with the American delegation in September 1782. The French and Spanish sought to improve their position by creating the U.S. dependent on them for support against Britain, thus reversing the losses of 1763. Both parties tried to negotiate a settlement with Britain excluding the Americans; France proposed setting the western boundary of the US along the Appalachians, matching the British 1763 Proclamation Line. The Spanish suggested additional concessions in the vital Mississippi River Basin, but required the cession of Georgia in violation of the Franco-American alliance. + +Facing difficulties with Spain over claims involving the Mississippi River, and from France who was still reluctant to agree to American independence until all her demands were met, John Jay promptly told the British that he was willing to negotiate directly with them, cutting off France and Spain, and Prime Minister Lord Shelburne, in charge of the British negotiations, agreed. Key agreements for the United States in obtaining peace included recognition of United States independence, including recognition that the U.S. would gain all of the area east of the Mississippi River, north of Florida and south of Canada, and the granting of fishing rights in the Grand Banks, off the coast of Newfoundland and in the Gulf of Saint Lawrence; the United States and Great Britain were each given perpetual access to the Mississippi River. + +An Anglo-American Preliminary Peace was formally entered into in November 1782, and Congress endorsed the settlement on April 15, 1783. It announced the achievement of peace with independence, and the conclusive treaty was signed on September 2, 1783, in Paris, effective the following day on September 3, 1783, when Britain signed its treaty with France. John Adams, who helped draft the treaty, claimed it represented "one of the most important political events that ever happened on the globe". Ratified respectively by Congress and Parliament, the final versions were exchanged in Paris the following spring. On November 25, the last British troops remaining in the U.S. were evacuated from New York to Halifax. + +Aftermath + +Washington expressed astonishment that the Americans had won a war against a leading world power, referring to the American victory as "little short of a standing miracle". The conflict between British subjects with the Crown against those with the Congress had lasted over eight years from 1775 to 1783. The last uniformed British troops departed their last East Coast port cities in Savannah, Charleston, and New York City, by November 25, 1783, which marked the end of British occupation in the new United States. + +On April 9, 1783, Washington issued orders that he had long waited to give, that "all acts of hostility" were to cease immediately. That same day, by arrangement with Washington, General Guy Carleton issued a similar order to British troops. British troops, however, were not to evacuate until a prisoner of war exchange occurred, an effort that involved much negotiation and would take some seven months to effect. + +As directed by a Congressional resolution of May 26, 1783, all non-commissioned officers and enlisted were furloughed "to their homes" until the "definitive treaty of peace", when they would be automatically discharged. The U.S. armies were directly disbanded in the field as of Washington's General Orders on Monday, June 2, 1783. Once the Treaty of Paris was signed with Britain on September 3, 1783, Washington resigned as commander-in-chief of the Continental Army and left to retire at Mount Vernon. + +Territory +The expanse of territory that was now the United States was ceded from its colonial mother country alone. It included millions of sparsely settled acres south of the Great Lakes line between the Appalachian Mountains and the Mississippi River, much of which was part of Canada. The tentative colonial migration west became a flood during the years of the Revolutionary War. Kentucky County, Virginia, for instance, had a 1775 population of 150. By 1790, 15 years later, its population had grown to over 73,000. + +Britain's extended post-war policy for the U.S. continued to try to establish an Indian buffer state below the Great Lakes as late as 1814 during the War of 1812. The formally acquired western American lands continued to be populated by a dozen or so American Indian tribes that had been British allies for the most part. Though British forts on their lands had been ceded to either the French or the British prior to the creation of the United States, Natives were not referred to in the British cession to the U.S. + +While tribes were not consulted by the British for the treaty, in practice the British refused to abandon the forts on territory they formally transferred. Instead, they provisioned military allies for continuing frontier raids and sponsored the Northwest Indian War (1785–1795), including erecting an additional British Fort Miami in Maumee, Ohio. British sponsorship of local warfare on the U.S. continued until the Anglo-American Jay Treaty, authored by Alexander Hamilton went into effect on February 29, 1796. At the same time, the Spanish also sponsored war within the U.S. by Indian proxies in its Southwest Territory ceded by France to Britain, then Britain to the Americans. + +Of the European powers with American colonies adjacent to the newly created United States, Spain was most threatened by American independence, and it was correspondingly the most hostile to it. Its territory adjacent to the U.S. was relatively undefended, so Spanish policy developed a combination of initiatives. Spanish soft power diplomatically challenged the British territorial cession west to the Mississippi River and the previous northern boundaries of Spanish Florida. It imposed a high tariff on American goods, then blocked American settler access to the port of New Orleans. Spanish hard power extended war alliances and arms to Southwestern Natives to resist American settlement. A former Continental Army General, James Wilkinson settled in Kentucky County, Virginia in 1784, and there he fostered settler secession from Virginia during the Spanish-allied Chickamauga Cherokee war. Beginning in 1787, he received pay as Spanish Agent 13, and subsequently expanded his efforts to persuade American settlers west of the Appalachian Mountains to secede from the United States, first in the Washington administration and later again in the Jefferson administration. + +Casualties and losses + +The total loss of life throughout the conflict is largely unknown. As was typical in wars of the era, diseases such as smallpox claimed more lives than battle. Between 1775 and 1782, a smallpox epidemic broke out throughout North America, killing an estimated 130,000 among all its populations during those years. Historian Joseph Ellis suggests that Washington's decision to have his troops inoculated against the disease was one of his most important decisions. + +Up to 70,000 American patriots died during active military service. Of these, approximately 6,800 were killed in battle, while at least 17,000 died from disease. The majority of the latter died while prisoners of war of the British, mostly in the prison ships in New York Harbor. The number of Patriots seriously wounded or disabled by the war has been estimated from 8,500 to 25,000. + +The French suffered 2,112 killed in combat in the United States. The Spanish lost a total of 124 killed and 247 wounded in West Florida. + +A British report in 1781 puts their total Army deaths at 6,046 in North America (1775–1779). Approximately 7,774 Germans died in British service in addition to 4,888 deserters; among those labeled German deserters, however, it is estimated that 1,800 were killed in combat. + +Legacy + +The American Revolution established the United States with its numerous civil liberties and set an example to overthrow both monarchy and colonial governments. The United States has the world's oldest written constitution, and the constitutions of other free countries often bear a striking resemblance to the U.S. Constitution, often word-for-word in places. It inspired revolutions in France, Haiti, Latin America, and elsewhere in the modern era. + +Although the Revolution eliminated many forms of inequality, it did little to change the status of women, despite the role they played in winning independence. Most significantly, it failed to end slavery which continued to be a serious social and political issue and caused divisions that would ultimately end in civil war. While many were uneasy over the contradiction of demanding liberty for some, yet denying it to others, the dependence of southern states on slave labor made abolition too great a challenge. Between 1774 and 1780, many of the states banned the importation of slaves, but the institution itself continued. + +In 1782, Virginia passed a law permitting manumission and over the next eight years more than 10,000 slaves were given their freedom. With support from Benjamin Franklin, in 1790 the Quakers petitioned Congress to abolish slavery; the number of abolitionist movements greatly increased, and by 1804 all the northern states had outlawed it. However, even many like Adams who viewed slavery as a 'foul contagion' opposed the 1790 petition as a threat to the Union. In 1808, Jefferson passed legislation banning the importation of slaves, but allowed the domestic slave trade to continue, arguing the federal government had no right to regulate individual states. + +Historiography +The body of historical writings on the American Revolution cite many motivations for the Patriot revolt that ultimately led to the nation's independence and establishment. American patriots stressed the denial of their constitutional rights as Englishmen, especially "no taxation without representation." Contemporaries credit the American Enlightenment with laying the intellectual, moral, and ethical foundations for the American Revolution among the Founding Fathers, who were influenced by the classical liberalism of John Locke and other enlightenment age writers and philosophers. + +Two Treatises of Government has long been cited as a major influence on Revolutionary-era American thinking, but historians David Lundberg and Henry F. May contend that Locke's Essay Concerning Human Understanding was far more widely read than were his political Treatises. Historians since the 1960s have emphasized that the Patriot constitutional argument was made possible by the emergence of a sense of American nationalism that united the 13 colonies. In turn, that nationalism was rooted in a Republican value system that demanded consent of the governed and deeply opposed aristocratic control. In Britain, on the other hand, republicanism was largely a fringe ideology since it challenged the aristocratic control of the British monarchy and political system. Political power was not controlled by an aristocracy or nobility in the 13 colonies; instead, the colonial political system was based on the winners of free elections, which were open at the time to the majority of white men. In analysis of the Revolution, historians in recent decades have often cited three motivations behind it: + The Atlantic history view places the American story in a broader context, including subsequent revolutions in France and Haiti. It tends to reintegrate the historiographies of the American Revolution and the British Empire. + The "new social history" approach looks at community social structure to find cleavages that were magnified into colonial cleavages. + The ideological approach that centers on republicanism in the United States. Republicanism dictated there would be no royalty, aristocracy or national church but allowed for continuation of the British common law, which American lawyers and jurists understood and approved and used in their everyday practice. Historians have examined how the rising American legal profession adopted British common law to incorporate republicanism by selective revision of legal customs and by introducing more choices for courts. + +Revolutionary War commemoration stamps +After the first U.S. postage stamp was issued in 1849, the U.S. Postal Service frequently issued commemorative stamps celebrating the various people and events of the Revolutionary War. The first such stamp was the Liberty Bell issue of 1926 on the 150th anniversary of American independence. + +See also + + 1776 in the United States: events, births, deaths, and other years + Timeline of the American Revolution + +Topics of the Revolution + Committee of safety (American Revolution) + Diplomacy in the American Revolutionary War + Financial costs of the American Revolutionary War + Flags of the American Revolution + Naval operations in the American Revolutionary War + +Social history of the Revolution + Black Patriot + Christianity in the United States#American Revolution + The Colored Patriots of the American Revolution + History of Poles in the United States#American Revolution + List of clergy in the American Revolution + List of Patriots (American Revolution) + Quakers in the American Revolution + Scotch-Irish Americans#American Revolution + +Others in the American Revolution + Nova Scotia in the American Revolution + Watauga Association + +Lists of Revolutionary military + List of American Revolutionary War battles + List of British Forces in the American Revolutionary War + List of Continental Forces in the American Revolutionary War + List of infantry weapons in the American Revolution + List of United States militia units in the American Revolutionary War + +Thirteen Colony economy + Economic history of the US: Colonial economy to 1780 + Shipbuilding in the American colonies + Slavery in the United States + +Legacy and related + American Revolution Statuary + Commemoration of the American Revolution + Founders Online + Independence Day (United States) + The Last Men of the Revolution + List of plays and films about the American Revolution + Museum of the American Revolution + Tomb of the Unknown Soldier of the American Revolution + United States Bicentennial + United States Semiquincentennial + List of wars of independence + +Bibliographies + Bibliography of the American Revolutionary War + Bibliography of Thomas Jefferson + Bibliography of George Washington + +Notes + +Citations +Year dates enclosed in [brackets] denote year of original printing + +Bibliography + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Britannica.com + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Dictionary of American Biography + + + + + + + + + + + + + + + Encyclopædia Britannica + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + , p. 73 + + + + + + + + + + + + + + + + + + – Highly regarded examination of British strategy and leadership.

One ampere is equal to 1 coulomb moving past a point in 1 second, or electrons' worth of charge moving past a point in 1 second. It is named after French mathematician and physicist André-Marie Ampère (1775–1836), considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted. + +As of the 2019 redefinition of the SI base units, the ampere is defined by fixing the elementary charge to be exactly (coulomb), which means an ampere is an electric current equivalent to elementary charges moving every seconds or elementary charges moving in a second. Prior to the redefinition the ampere was defined as the current passing through 2 parallel wires 1 metre apart that produces a magnetic force of newtons per metre. + +The earlier CGS system has two units of current, one structured similar to the SI's and the other using Coulomb's law as a fundamental relationship, with the unit of charge defined by measuring the force between two charged metal plates. The unit of current is then defined as one unit of charge per second. In SI, the unit of charge, the coulomb, is defined as the charge carried by one ampere during one second. + +History + +The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics. In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of electrical measurement for electric current. + +The ampere was originally defined as one tenth of the unit of electric current in the centimetre–gram–second system of units. That unit, now known as the abampere, was defined as the amount of current that generates a force of two dynes per centimetre of length between two wires one centimetre apart. The size of the unit was chosen so that the units derived from it in the MKSA system would be conveniently sized. + +The "international ampere" was an early realization of the ampere, defined as the current that would deposit of silver per second from a silver nitrate solution. Later, more accurate measurements revealed that this current is . + +Since power is defined as the product of current and voltage, the ampere can alternatively be expressed in terms of the other units using the relationship , and thus 1 A = 1 W/V. Current can be measured by a multimeter, a device that can measure electrical voltage, current, and resistance. + +Former definition in the SI +Until 2019, the SI defined the ampere as follows: +The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to newtons per metre of length. + +Ampère's force law states that there is an attractive or repulsive force between two parallel wires carrying an electric current. This force is used in the formal definition of the ampere. + +The SI unit of charge, the coulomb, was then defined as "the quantity of electricity carried in 1 second by a current of 1 ampere". Conversely, a current of one ampere is one coulomb of charge going past a given point per second: + +In general, charge was determined by steady current flowing for a time as . + +This definition of the ampere was most accurately realised using a Kibble balance, but in practice the unit was maintained via Ohm's law from the units of electromotive force and resistance, the volt and the ohm, since the latter two could be tied to physical phenomena that are relatively easy to reproduce, the Josephson effect and the quantum Hall effect, respectively. + +Techniques to establish the realisation of an ampere had a relative uncertainty of approximately a few parts in 10, and involved realisations of the watt, the ohm and the volt. + +Present definition +The 2019 redefinition of the SI base units defined the ampere by taking the fixed numerical value of the elementary charge to be when expressed in the unit C, which is equal to A⋅s, where the second is defined in terms of , the unperturbed ground state hyperfine transition frequency of the caesium-133 atom. + +The SI unit of charge, the coulomb, "is the quantity of electricity carried in 1 second by a current of 1 ampere". Conversely, a current of one ampere is one coulomb of charge going past a given point per second: + +In general, charge is determined by steady current flowing for a time as . + +Constant, instantaneous and average current are expressed in amperes (as in "the charging current is 1.2 A") and the charge accumulated (or passed through a circuit) over a period of time is expressed in coulombs (as in "the battery charge is "). The relation of the ampere (C/s) to the coulomb is the same as that of the watt (J/s) to the joule. + +Units derived from the ampere +The international system of units (SI) is based on 7 SI base units the second, metre, kilogram, kelvin, ampere, mole, and candela representing 7 fundamental types of physical quantity, or "dimensions", (time, length, mass, temperature, electric current, amount of substance, and luminous intensity respectively) with all other SI units being defined using these. These SI derived units can either be given special names e.g. watt, volt, lux, etc. or defined in terms of others, e.g. metre per second. The units with special names derived from the ampere are: + +There are also some SI units that are frequently used in the context of electrical engineering and electrical appliances, but can be defined independently of the ampere, notably the hertz, joule, watt, candela, lumen, and lux. + +SI prefixes + +Like other SI units, the ampere can be modified by adding a prefix that multiplies it by a power of 10. + +See also + Ammeter + Ampacity (current-carrying capacity) + Electric current + Electric shock + Hydraulic analogy + Magnetic constant + Orders of magnitude (current) + +References + +External links + The NIST Reference on Constants, Units, and Uncertainty + NIST Definition of ampere and μ0 + +SI base units +Units of electric current +In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can use conditionals to divert the code execution through various routes (referred to as automated decision-making) and deduce valid inferences (referred to as automated reasoning), achieving automation eventually. Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". + +In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. + +As an effective method, an algorithm can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input. + +History + +Ancient algorithms +Since antiquity, step-by-step procedures for solving mathematical problems have been attested. This includes Babylonian mathematics (around 2500 BC), Egyptian mathematics (around 1550 BC), Indian mathematics (around 800 BC and later; e.g. Shulba Sutras, Kerala School, and Brāhmasphuṭasiddhānta), The Ifa Oracle (around 500 BC), Greek mathematics (around 240 BC, e.g. sieve of Eratosthenes and Euclidean algorithm), and Arabic mathematics (9th century, e.g. cryptographic algorithms for code-breaking based on frequency analysis). + +Al-Khwārizmī and the term algorithm +Around 825, Muḥammad ibn Mūsā al-Khwārizmī wrote kitāb al-ḥisāb al-hindī ("Book of Indian computation") and kitab al-jam' wa'l-tafriq al-ḥisāb al-hindī ("Addition and subtraction in Indian arithmetic"). Both of these texts are lost in the original Arabic at this time. (However, his other book on algebra remains.) + +In the early 12th century, Latin translations of said al-Khwarizmi texts involving the Hindu–Arabic numeral system and arithmetic appeared: Liber Alghoarismi de practica arismetrice (attributed to John of Seville) and Liber Algorismi de numero Indorum (attributed to Adelard of Bath). Hereby, alghoarismi or algorismi is the Latinization of Al-Khwarizmi's name; the text starts with the phrase Dixit Algorismi ("Thus spoke Al-Khwarizmi"). + +In 1240, Alexander of Villedieu writes a Latin text titled Carmen de Algorismo. It begins with: + +which translates to: + +The poem is a few hundred lines long and summarizes the art of calculating with the new styled Indian dice (Tali Indorum), or Hindu numerals. + +English evolution of the word +Around 1230, the English word algorism is attested and then by Chaucer in 1391. English adopted the French term. + +In the 15th century, under the influence of the Greek word ἀριθμός (arithmos, "number"; cf. "arithmetic"), the Latin word was altered to algorithmus. + +In 1656, in the English dictionary Glossographia, it says: + +Algorism ([Latin] algorismus) the Art or use of Cyphers, or of numbering by Cyphers; skill in accounting. + +Augrime ([Latin] algorithmus) skil in accounting or numbring. + +In 1658, in the first edition of The New World of English Words, it says: + +Algorithme, (a word compounded of Arabick and Spanish,) the art of reckoning by Cyphers. + +In 1706, in the sixth edition of The New World of English Words, it says: + +Algorithm, the Art of computing or reckoning by numbers, which contains the five principle Rules of Arithmetick, viz. Numeration, Addition, Subtraction, Multiplication and Division; to which may be added Extraction of Roots: It is also call'd Logistica Numeralis. + +Algorism, the practical Operation in the several Parts of Specious Arithmetick or Algebra; sometimes it is taken for the Practice of Common Arithmetick by the ten Numeral Figures. + +In 1751, in the Young Algebraist's Companion, Daniel Fenning contrasts the terms algorism and algorithm as follows: + +Algorithm signifies the first Principles, and Algorism the practical Part, or knowing how to put the Algorithm in Practice. + +, the term algorithm is attested to mean a "step-by-step procedure" in English. + +In 1842, in the Dictionary of Science, Literature and Art, it says: + +ALGORITHM, signifies the art of computing in reference to some particular subject, or in some particular way; as the algorithm of numbers; the algorithm of the differential calculus. + +Machine usage + +In 1928, a partial formalization of the modern concept of algorithms began with attempts to solve the Entscheidungsproblem (decision problem) posed by David Hilbert. Later formalizations were framed as attempts to define "effective calculability" or "effective method". Those formalizations included the Gödel–Herbrand–Kleene recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's Formulation 1 of 1936, and Alan Turing's Turing machines of 1936–37 and 1939. + +Informal definition + +One informal definition is "a set of rules that precisely defines a sequence of operations", which would include all computer programs (including programs that do not perform numeric calculations), and (for example) any prescribed bureaucratic procedure +or cook-book recipe. + +In general, a program is an algorithm only if it stops eventually—even though infinite loops may sometimes prove desirable. + +A prototypical example of an algorithm is the Euclidean algorithm, which is used to determine the maximum common divisor of two integers; an example (there are others) is described by the flowchart above and as an example in a later section. + + offer an informal meaning of the word "algorithm" in the following quotation: + +An "enumerably infinite set" is one whose elements can be put into one-to-one correspondence with the integers. Thus Boolos and Jeffrey are saying that an algorithm implies instructions for a process that "creates" output integers from an arbitrary "input" integer or integers that, in theory, can be arbitrarily large. For example, an algorithm can be an algebraic equation such as y = m + n (i.e., two arbitrary "input variables" m and n that produce an output y), but various authors' attempts to define the notion indicate that the word implies much more than this, something on the order of (for the addition example): +Precise instructions (in a language understood by "the computer") for a fast, efficient, "good" process that specifies the "moves" of "the computer" (machine or human, equipped with the necessary internally contained information and capabilities) to find, decode, and then process arbitrary input integers/symbols m and n, symbols + and = ... and "effectively" produce, in a "reasonable" time, output-integer y at a specified place and in a specified format. + +The concept of algorithm is also used to define the notion of decidability—a notion that is central for explaining how formal systems come into being starting from a small set of axioms and rules. In logic, the time that an algorithm requires to complete cannot be measured, as it is not apparently related to the customary physical dimension. From such uncertainties, that characterize ongoing work, stems the unavailability of a definition of algorithm that suits both concrete (in some sense) and abstract usage of the term. + +Most algorithms are intended to be implemented as computer programs. However, algorithms are also implemented by other means, such as in a biological neural network (for example, the human brain implementing arithmetic or an insect looking for food), in an electrical circuit, or in a mechanical device. + +Formalization + +Algorithms are essential to the way computers process data. Many computer programs contain algorithms that detail the specific instructions a computer should perform—in a specific order—to carry out a specified task, such as calculating employees' paychecks or printing students' report cards. Thus, an algorithm can be considered to be any sequence of operations that can be simulated by a Turing-complete system. Authors who assert this thesis include Minsky (1967), Savage (1987), and Gurevich (2000): +Turing machines can define computational processes that do not terminate. The informal definitions of algorithms generally require that the algorithm always terminates. This requirement renders the task of deciding whether a formal procedure is an algorithm impossible in the general case—due to a major theorem of computability theory known as the halting problem. + +Typically, when an algorithm is associated with processing information, data can be read from an input source, written to an output device and stored for further processing. Stored data are regarded as part of the internal state of the entity performing the algorithm. In practice, the state is stored in one or more data structures. + +For some of these computational processes, the algorithm must be rigorously defined: and specified in the way it applies in all possible circumstances that could arise. This means that any conditional steps must be systematically dealt with, case by case; the criteria for each case must be clear (and computable). + +Because an algorithm is a precise list of precise steps, the order of computation is always crucial to the functioning of the algorithm. Instructions are usually assumed to be listed explicitly, and are described as starting "from the top" and going "down to the bottom"—an idea that is described more formally by flow of control. + +So far, the discussion on the formalization of an algorithm has assumed the premises of imperative programming. This is the most common conception—one that attempts to describe a task in discrete, "mechanical" means. Associated with this conception of formalized algorithms is the assignment operation, which sets the value of a variable. It derives from the intuition of "memory" as a scratchpad. An example of such an assignment can be found below. + +For some alternate conceptions of what constitutes an algorithm, see functional programming and logic programming. + +Expressing algorithms +Algorithms can be expressed in many kinds of notation, including natural languages, pseudocode, flowcharts, drakon-charts, programming languages or control tables (processed by interpreters). Natural language expressions of algorithms tend to be verbose and ambiguous, and are rarely used for complex or technical algorithms. Pseudocode, flowcharts, drakon-charts and control tables are structured ways to express algorithms that avoid many of the ambiguities common in the statements based on natural language. Programming languages are primarily intended for expressing algorithms in a form that can be executed by a computer, but are also often used as a way to define or document algorithms. + +There is a wide variety of representations possible and one can express a given Turing machine program as a sequence of machine tables (see finite-state machine, state-transition table and control table for more), as flowcharts and drakon-charts (see state diagram for more), or as a form of rudimentary machine code or assembly code called "sets of quadruples" (see Turing machine for more). + +Representations of algorithms can be classed into three accepted levels of Turing machine description, as follows: + 1 High-level description + "...prose to describe an algorithm, ignoring the implementation details. At this level, we do not need to mention how the machine manages its tape or head." + 2 Implementation description + "...prose used to define the way the Turing machine uses its head and the way that it stores data on its tape. At this level, we do not give details of states or transition function." + 3 Formal description + Most detailed, "lowest level", gives the Turing machine's "state table". + +For an example of the simple algorithm "Add m+n" described in all three levels, see Examples. + +Design + +Algorithm design refers to a method or a mathematical process for problem-solving and engineering algorithms. The design of algorithms is part of many solution theories, such as divide-and-conquer or dynamic programming within operation research. Techniques for designing and implementing algorithm designs are also called algorithm design patterns, with examples including the template method pattern and the decorator pattern. + +One of the most important aspects of algorithm design is resource (run-time, memory usage) efficiency; the big O notation is used to describe e.g. an algorithm's run-time growth as the size of its input increases. + +Typical steps in the development of algorithms: + Problem definition + Development of a model + Specification of the algorithm + Designing an algorithm + Checking the correctness of the algorithm + Analysis of algorithm + Implementation of algorithm + Program testing + Documentation preparation + +Computer algorithms + +"Elegant" (compact) programs, "good" (fast) programs : The notion of "simplicity and elegance" appears informally in Knuth and precisely in Chaitin: +Knuth: " ... we want good algorithms in some loosely defined aesthetic sense. One criterion ... is the length of time taken to perform the algorithm .... Other criteria are adaptability of the algorithm to computers, its simplicity, and elegance, etc." + +Chaitin: " ... a program is 'elegant,' by which I mean that it's the smallest possible program for producing the output that it does" + +Chaitin prefaces his definition with: "I'll show you can't prove that a program is 'elegant—such a proof would solve the Halting problem (ibid). + +Algorithm versus function computable by an algorithm: For a given function multiple algorithms may exist. This is true, even without expanding the available instruction set available to the programmer. Rogers observes that "It is ... important to distinguish between the notion of algorithm, i.e. procedure and the notion of function computable by algorithm, i.e. mapping yielded by procedure. The same function may have several different algorithms". + +Unfortunately, there may be a tradeoff between goodness (speed) and elegance (compactness)—an elegant program may take more steps to complete a computation than one less elegant. An example that uses Euclid's algorithm appears below. + +Computers (and computors), models of computation: A computer (or human "computer") is a restricted type of machine, a "discrete deterministic mechanical device" that blindly follows its instructions. Melzak's and Lambek's primitive models reduced this notion to four elements: (i) discrete, distinguishable locations, (ii) discrete, indistinguishable counters (iii) an agent, and (iv) a list of instructions that are effective relative to the capability of the agent. + +Minsky describes a more congenial variation of Lambek's "abacus" model in his "Very Simple Bases for Computability". Minsky's machine proceeds sequentially through its five (or six, depending on how one counts) instructions unless either a conditional IF-THEN GOTO or an unconditional GOTO changes program flow out of sequence. Besides HALT, Minsky's machine includes three assignment (replacement, substitution) operations: ZERO (e.g. the contents of location replaced by 0: L ← 0), SUCCESSOR (e.g. L ← L+1), and DECREMENT (e.g. L ← L − 1). Rarely must a programmer write "code" with such a limited instruction set. But Minsky shows (as do Melzak and Lambek) that his machine is Turing complete with only four general types of instructions: conditional GOTO, unconditional GOTO, assignment/replacement/substitution, and HALT. However, a few different assignment instructions (e.g. DECREMENT, INCREMENT, and ZERO/CLEAR/EMPTY for a Minsky machine) are also required for Turing-completeness; their exact specification is somewhat up to the designer. The unconditional GOTO is convenient; it can be constructed by initializing a dedicated location to zero e.g. the instruction " Z ← 0 "; thereafter the instruction IF Z=0 THEN GOTO xxx is unconditional. + +Simulation of an algorithm: computer (computor) language: Knuth advises the reader that "the best way to learn an algorithm is to try it . . . immediately take pen and paper and work through an example". But what about a simulation or execution of the real thing? The programmer must translate the algorithm into a language that the simulator/computer/computor can effectively execute. Stone gives an example of this: when computing the roots of a quadratic equation the computer must know how to take a square root. If they do not, then the algorithm, to be effective, must provide a set of rules for extracting a square root. + +This means that the programmer must know a "language" that is effective relative to the target computing agent (computer/computor). + +But what model should be used for the simulation? Van Emde Boas observes "even if we base complexity theory on abstract instead of concrete machines, the arbitrariness of the choice of a model remains. It is at this point that the notion of simulation enters". When speed is being measured, the instruction set matters. For example, the subprogram in Euclid's algorithm to compute the remainder would execute much faster if the programmer had a "modulus" instruction available rather than just subtraction (or worse: just Minsky's "decrement"). + +Structured programming, canonical structures: Per the Church–Turing thesis, any algorithm can be computed by a model known to be Turing complete, and per Minsky's demonstrations, Turing completeness requires only four instruction types—conditional GOTO, unconditional GOTO, assignment, HALT. Kemeny and Kurtz observe that, while "undisciplined" use of unconditional GOTOs and conditional IF-THEN GOTOs can result in "spaghetti code", a programmer can write structured programs using only these instructions; on the other hand "it is also possible, and not too hard, to write badly structured programs in a structured language". Tausworthe augments the three Böhm-Jacopini canonical structures: SEQUENCE, IF-THEN-ELSE, and WHILE-DO, with two more: DO-WHILE and CASE. An additional benefit of a structured program is that it lends itself to proofs of correctness using mathematical induction. + +Canonical flowchart symbols: The graphical aide called a flowchart offers a way to describe and document an algorithm (and a computer program corresponding to it). Like the program flow of a Minsky machine, a flowchart always starts at the top of a page and proceeds down. Its primary symbols are only four: the directed arrow showing program flow, the rectangle (SEQUENCE, GOTO), the diamond (IF-THEN-ELSE), and the dot (OR-tie). The Böhm–Jacopini canonical structures are made of these primitive shapes. Sub-structures can "nest" in rectangles, but only if a single exit occurs from the superstructure. The symbols and their use to build the canonical structures are shown in the diagram. + +Examples + +Algorithm example +One of the simplest algorithms is to find the largest number in a list of numbers of random order. Finding the solution requires looking at every number in the list. From this follows a simple algorithm, which can be stated in a high-level description in English prose, as: + +High-level description: + If there are no numbers in the set, then there is no highest number. + Assume the first number in the set is the largest number in the set. + For each remaining number in the set: if this number is larger than the current largest number, consider this number to be the largest number in the set. + When there are no numbers left in the set to iterate over, consider the current largest number to be the largest number of the set. + +(Quasi-)formal description: +Written in prose but much closer to the high-level language of a computer program, the following is the more formal coding of the algorithm in pseudocode or pidgin code: + + Input: A list of numbers L. + Output: The largest number in the list L. + + if L.size = 0 return null + largest ← L[0] + for each item in L, do + if item > largest, then + largest ← item + return largest + +Euclid's algorithm + +In mathematics, the Euclidean algorithm or Euclid's algorithm, is an efficient method for computing the greatest common divisor (GCD) of two integers (numbers), the largest number that divides them both without a remainder. It is named after the ancient Greek mathematician Euclid, who first described it in his Elements (). It is one of the oldest algorithms in common use. It can be used to reduce fractions to their simplest form, and is a part of many other number-theoretic and cryptographic calculations. + +Euclid poses the problem thus: "Given two numbers not prime to one another, to find their greatest common measure". He defines "A number [to be] a multitude composed of units": a counting number, a positive integer not including zero. To "measure" is to place a shorter measuring length s successively (q times) along longer length l until the remaining portion r is less than the shorter length s. In modern words, remainder r = l − q×s, q being the quotient, or remainder r is the "modulus", the integer-fractional part left over after the division. + +For Euclid's method to succeed, the starting lengths must satisfy two requirements: (i) the lengths must not be zero, AND (ii) the subtraction must be "proper"; i.e., a test must guarantee that the smaller of the two numbers is subtracted from the larger (or the two can be equal so their subtraction yields zero). + +Euclid's original proof adds a third requirement: the two lengths must not be prime to one another. Euclid stipulated this so that he could construct a reductio ad absurdum proof that the two numbers' common measure is in fact the greatest. While Nicomachus' algorithm is the same as Euclid's, when the numbers are prime to one another, it yields the number "1" for their common measure. So, to be precise, the following is really Nicomachus' algorithm. + +Computer language for Euclid's algorithm +Only a few instruction types are required to execute Euclid's algorithm—some logical tests (conditional GOTO), unconditional GOTO, assignment (replacement), and subtraction. + A location is symbolized by upper case letter(s), e.g. S, A, etc. + The varying quantity (number) in a location is written in lower case letter(s) and (usually) associated with the location's name. For example, location L at the start might contain the number l = 3009. + +An inelegant program for Euclid's algorithm + +The following algorithm is framed as Knuth's four-step version of Euclid's and Nicomachus', but, rather than using division to find the remainder, it uses successive subtractions of the shorter length s from the remaining length r until r is less than s. The high-level description, shown in boldface, is adapted from Knuth 1973:2–4: + +INPUT: + [Into two locations L and S put the numbers l and s that represent the two lengths]: + INPUT L, S + [Initialize R: make the remaining length r equal to the starting/initial/input length l]: + R ← L + +E0: [Ensure r ≥ s.] + [Ensure the smaller of the two numbers is in S and the larger in R]: + IF R > S THEN + the contents of L is the larger number so skip over the exchange-steps 4, 5 and 6: + GOTO step 7 + ELSE + swap the contents of R and S. + L ← R (this first step is redundant, but is useful for later discussion). + R ← S + S ← L + +E1: [Find remainder]: Until the remaining length r in R is less than the shorter length s in S, repeatedly subtract the measuring number s in S from the remaining length r in R. + IF S > R THEN + done measuring so + GOTO 10 + ELSE + measure again, + R ← R − S + [Remainder-loop]: + GOTO 7. + +E2: [Is the remainder zero?]: EITHER (i) the last measure was exact, the remainder in R is zero, and the program can halt, OR (ii) the algorithm must continue: the last measure left a remainder in R less than measuring number in S. + IF R = 0 THEN + done so + GOTO step 15 + ELSE + CONTINUE TO step 11, + +E3: [Interchange s and r]: The nut of Euclid's algorithm. Use remainder r to measure what was previously smaller number s; L serves as a temporary location. + L ← R + R ← S + S ← L + [Repeat the measuring process]: + GOTO 7 + +OUTPUT: + + [Done. S contains the greatest common divisor]: + PRINT S + +DONE: + HALT, END, STOP. + +An elegant program for Euclid's algorithm + The flowchart of "Elegant" can be found at the top of this article. In the (unstructured) Basic language, the steps are numbered, and the instruction LET [] = [] is the assignment instruction symbolized by ←. +5 REM Euclid's algorithm for greatest common divisor +6 PRINT "Type two integers greater than 0" +10 INPUT A,B +20 IF B=0 THEN GOTO 80 +30 IF A > B THEN GOTO 60 +40 LET B=B-A +50 GOTO 20 +60 LET A=A-B +70 GOTO 20 +80 PRINT A +90 END +How "Elegant" works: In place of an outer "Euclid loop", "Elegant" shifts back and forth between two "co-loops", an A > B loop that computes A ← A − B, and a B ≤ A loop that computes B ← B − A. This works because, when at last the minuend M is less than or equal to the subtrahend S (Difference = Minuend − Subtrahend), the minuend can become s (the new measuring length) and the subtrahend can become the new r (the length to be measured); in other words the "sense" of the subtraction reverses. + +The following version can be used with programming languages from the C-family: +// Euclid's algorithm for greatest common divisor +int euclidAlgorithm (int A, int B) { + A = abs(A); + B = abs(B); + while (B != 0) { + while (A > B) { + A = A-B; + } + B = B-A; + } + return A; +} + +Testing the Euclid algorithms +Does an algorithm do what its author wants it to do? A few test cases usually give some confidence in the core functionality. But tests are not enough. For test cases, one source uses 3009 and 884. Knuth suggested 40902, 24140. Another interesting case is the two relatively prime numbers 14157 and 5950. + +But "exceptional cases" must be identified and tested. Will "Inelegant" perform properly when R > S, S > R, R = S? Ditto for "Elegant": B > A, A > B, A = B? (Yes to all). What happens when one number is zero, both numbers are zero? ("Inelegant" computes forever in all cases; "Elegant" computes forever when A = 0.) What happens if negative numbers are entered? Fractional numbers? If the input numbers, i.e. the domain of the function computed by the algorithm/program, is to include only positive integers including zero, then the failures at zero indicate that the algorithm (and the program that instantiates it) is a partial function rather than a total function. A notable failure due to exceptions is the Ariane 5 Flight 501 rocket failure (June 4, 1996). + +Proof of program correctness by use of mathematical induction: Knuth demonstrates the application of mathematical induction to an "extended" version of Euclid's algorithm, and he proposes "a general method applicable to proving the validity of any algorithm". Tausworthe proposes that a measure of the complexity of a program be the length of its correctness proof. + +Measuring and improving the Euclid algorithms +Elegance (compactness) versus goodness (speed): With only six core instructions, "Elegant" is the clear winner, compared to "Inelegant" at thirteen instructions. However, "Inelegant" is faster (it arrives at HALT in fewer steps). Algorithm analysis indicates why this is the case: "Elegant" does two conditional tests in every subtraction loop, whereas "Inelegant" only does one. As the algorithm (usually) requires many loop-throughs, on average much time is wasted doing a "B = 0?" test that is needed only after the remainder is computed. + +Can the algorithms be improved?: Once the programmer judges a program "fit" and "effective"—that is, it computes the function intended by its author—then the question becomes, can it be improved? + +The compactness of "Inelegant" can be improved by the elimination of five steps. But Chaitin proved that compacting an algorithm cannot be automated by a generalized algorithm; rather, it can only be done heuristically; i.e., by exhaustive search (examples to be found at Busy beaver), trial and error, cleverness, insight, application of inductive reasoning, etc. Observe that steps 4, 5 and 6 are repeated in steps 11, 12 and 13. Comparison with "Elegant" provides a hint that these steps, together with steps 2 and 3, can be eliminated. This reduces the number of core instructions from thirteen to eight, which makes it "more elegant" than "Elegant", at nine steps. + +The speed of "Elegant" can be improved by moving the "B=0?" test outside of the two subtraction loops. This change calls for the addition of three instructions (B = 0?, A = 0?, GOTO). Now "Elegant" computes the example-numbers faster; whether this is always the case for any given A, B, and R, S would require a detailed analysis. + +Algorithmic analysis + +It is frequently important to know how much of a particular resource (such as time or storage) is theoretically required for a given algorithm. Methods have been developed for the analysis of algorithms to obtain such quantitative answers (estimates); for example, an algorithm which adds up the elements of a list of n numbers would have a time requirement of , using big O notation. At all times the algorithm only needs to remember two values: the sum of all the elements so far, and its current position in the input list. Therefore, it is said to have a space requirement of , if the space required to store the input numbers is not counted, or if it is counted. + +Different algorithms may complete the same task with a different set of instructions in less or more time, space, or 'effort' than others. For example, a binary search algorithm (with cost ) outperforms a sequential search (cost ) when used for table lookups on sorted lists or arrays. + +Formal versus empirical + +The analysis, and study of algorithms is a discipline of computer science, and is often practiced abstractly without the use of a specific programming language or implementation. In this sense, algorithm analysis resembles other mathematical disciplines in that it focuses on the underlying properties of the algorithm and not on the specifics of any particular implementation. Usually pseudocode is used for analysis as it is the simplest and most general representation. However, ultimately, most algorithms are usually implemented on particular hardware/software platforms and their algorithmic efficiency is eventually put to the test using real code. For the solution of a "one off" problem, the efficiency of a particular algorithm may not have significant consequences (unless n is extremely large) but for algorithms designed for fast interactive, commercial or long life scientific usage it may be critical. Scaling from small n to large n frequently exposes inefficient algorithms that are otherwise benign. + +Empirical testing is useful because it may uncover unexpected interactions that affect performance. Benchmarks may be used to compare before/after potential improvements to an algorithm after program optimization. +Empirical tests cannot replace formal analysis, though, and are not trivial to perform in a fair manner. + +Execution efficiency + +To illustrate the potential improvements possible even in well-established algorithms, a recent significant innovation, relating to FFT algorithms (used heavily in the field of image processing), can decrease processing time up to 1,000 times for applications like medical imaging. In general, speed improvements depend on special properties of the problem, which are very common in practical applications. Speedups of this magnitude enable computing devices that make extensive use of image processing (like digital cameras and medical equipment) to consume less power. + +Classification +There are various ways to classify algorithms, each with its own merits. + +By implementation +One way to classify algorithms is by implementation means. + + Recursion + A recursive algorithm is one that invokes (makes reference to) itself repeatedly until a certain condition (also known as termination condition) matches, which is a method common to functional programming. Iterative algorithms use repetitive constructs like loops and sometimes additional data structures like stacks to solve the given problems. Some problems are naturally suited for one implementation or the other. For example, towers of Hanoi is well understood using recursive implementation. Every recursive version has an equivalent (but possibly more or less complex) iterative version, and vice versa. + Serial, parallel or distributed + Algorithms are usually discussed with the assumption that computers execute one instruction of an algorithm at a time. Those computers are sometimes called serial computers. An algorithm designed for such an environment is called a serial algorithm, as opposed to parallel algorithms or distributed algorithms. Parallel algorithms are algorithms that take advantage of computer architectures where multiple processors can work on a problem at the same time. Distributed algorithms are algorithms that use multiple machines connected with a computer network. Parallel and distributed algorithms divide the problem into more symmetrical or asymmetrical subproblems and collect the results back together. For example, a CPU would be an example of a parallel algorithm. The resource consumption in such algorithms is not only processor cycles on each processor but also the communication overhead between the processors. Some sorting algorithms can be parallelized efficiently, but their communication overhead is expensive. Iterative algorithms are generally parallelizable, but some problems have no parallel algorithms and are called inherently serial problems. + Deterministic or non-deterministic + Deterministic algorithms solve the problem with exact decision at every step of the algorithm whereas non-deterministic algorithms solve problems via guessing although typical guesses are made more accurate through the use of heuristics. + Exact or approximate + While many algorithms reach an exact solution, approximation algorithms seek an approximation that is closer to the true solution. The approximation can be reached by either using a deterministic or a random strategy. Such algorithms have practical value for many hard problems. One of the examples of an approximate algorithm is the Knapsack problem, where there is a set of given items. Its goal is to pack the knapsack to get the maximum total value. Each item has some weight and some value. Total weight that can be carried is no more than some fixed number X. So, the solution must consider weights of items as well as their value. + Quantum algorithm + They run on a realistic model of quantum computation. The term is usually used for those algorithms which seem inherently quantum, or use some essential feature of Quantum computing such as quantum superposition or quantum entanglement. + +By design paradigm +Another way of classifying algorithms is by their design methodology or paradigm. There is a certain number of paradigms, each different from the other. Furthermore, each of these categories includes many different types of algorithms. Some common paradigms are: + + Brute-force or exhaustive search + Brute force is a method of problem-solving that involves systematically trying every possible option until the optimal solution is found. This approach can be very time consuming, as it requires going through every possible combination of variables. However, it is often used when other methods are not available or too complex. Brute force can be used to solve a variety of problems, including finding the shortest path between two points and cracking passwords. + Divide and conquer + A divide-and-conquer algorithm repeatedly reduces an instance of a problem to one or more smaller instances of the same problem (usually recursively) until the instances are small enough to solve easily. One such example of divide and conquer is merge sorting. Sorting can be done on each segment of data after dividing data into segments and sorting of entire data can be obtained in the conquer phase by merging the segments. A simpler variant of divide and conquer is called a decrease-and-conquer algorithm, which solves an identical subproblem and uses the solution of this subproblem to solve the bigger problem. Divide and conquer divides the problem into multiple subproblems and so the conquer stage is more complex than decrease and conquer algorithms. An example of a decrease and conquer algorithm is the binary search algorithm. + Search and enumeration + Many problems (such as playing chess) can be modeled as problems on graphs. A graph exploration algorithm specifies rules for moving around a graph and is useful for such problems. This category also includes search algorithms, branch and bound enumeration and backtracking. +Randomized algorithm + Such algorithms make some choices randomly (or pseudo-randomly). They can be very useful in finding approximate solutions for problems where finding exact solutions can be impractical (see heuristic method below). For some of these problems, it is known that the fastest approximations must involve some randomness. Whether randomized algorithms with polynomial time complexity can be the fastest algorithms for some problems is an open question known as the P versus NP problem. There are two large classes of such algorithms: + Monte Carlo algorithms return a correct answer with high-probability. E.g. RP is the subclass of these that run in polynomial time. + Las Vegas algorithms always return the correct answer, but their running time is only probabilistically bound, e.g. ZPP. + Reduction of complexity + This technique involves solving a difficult problem by transforming it into a better-known problem for which we have (hopefully) asymptotically optimal algorithms. The goal is to find a reducing algorithm whose complexity is not dominated by the resulting reduced algorithm's. For example, one selection algorithm for finding the median in an unsorted list involves first sorting the list (the expensive portion) and then pulling out the middle element in the sorted list (the cheap portion). This technique is also known as transform and conquer. + Back tracking + In this approach, multiple solutions are built incrementally and abandoned when it is determined that they cannot lead to a valid full solution. + +Optimization problems +For optimization problems there is a more specific classification of algorithms; an algorithm for such problems may fall into one or more of the general categories described above as well as into one of the following: + + Linear programming + When searching for optimal solutions to a linear function bound to linear equality and inequality constraints, the constraints of the problem can be used directly in producing the optimal solutions. There are algorithms that can solve any problem in this category, such as the popular simplex algorithm. Problems that can be solved with linear programming include the maximum flow problem for directed graphs. If a problem additionally requires that one or more of the unknowns must be an integer then it is classified in integer programming. A linear programming algorithm can solve such a problem if it can be proved that all restrictions for integer values are superficial, i.e., the solutions satisfy these restrictions anyway. In the general case, a specialized algorithm or an algorithm that finds approximate solutions is used, depending on the difficulty of the problem. + Dynamic programming + When a problem shows optimal substructures—meaning the optimal solution to a problem can be constructed from optimal solutions to subproblems—and overlapping subproblems, meaning the same subproblems are used to solve many different problem instances, a quicker approach called dynamic programming avoids recomputing solutions that have already been computed. For example, Floyd–Warshall algorithm, the shortest path to a goal from a vertex in a weighted graph can be found by using the shortest path to the goal from all adjacent vertices. Dynamic programming and memoization go together. The main difference between dynamic programming and divide and conquer is that subproblems are more or less independent in divide and conquer, whereas subproblems overlap in dynamic programming. The difference between dynamic programming and straightforward recursion is in caching or memoization of recursive calls. When subproblems are independent and there is no repetition, memoization does not help; hence dynamic programming is not a solution for all complex problems. By using memoization or maintaining a table of subproblems already solved, dynamic programming reduces the exponential nature of many problems to polynomial complexity. + The greedy method + A greedy algorithm is similar to a dynamic programming algorithm in that it works by examining substructures, in this case not of the problem but of a given solution. Such algorithms start with some solution, which may be given or have been constructed in some way, and improve it by making small modifications. For some problems they can find the optimal solution while for others they stop at local optima, that is, at solutions that cannot be improved by the algorithm but are not optimum. The most popular use of greedy algorithms is for finding the minimal spanning tree where finding the optimal solution is possible with this method. Huffman Tree, Kruskal, Prim, Sollin are greedy algorithms that can solve this optimization problem. +The heuristic method +In optimization problems, heuristic algorithms can be used to find a solution close to the optimal solution in cases where finding the optimal solution is impractical. These algorithms work by getting closer and closer to the optimal solution as they progress. In principle, if run for an infinite amount of time, they will find the optimal solution. Their merit is that they can find a solution very close to the optimal solution in a relatively short time. Such algorithms include local search, tabu search, simulated annealing, and genetic algorithms. Some of them, like simulated annealing, are non-deterministic algorithms while others, like tabu search, are deterministic. When a bound on the error of the non-optimal solution is known, the algorithm is further categorized as an approximation algorithm. + +By field of study + +Every field of science has its own problems and needs efficient algorithms. Related problems in one field are often studied together. Some example classes are search algorithms, sorting algorithms, merge algorithms, numerical algorithms, graph algorithms, string algorithms, computational geometric algorithms, combinatorial algorithms, medical algorithms, machine learning, cryptography, data compression algorithms and parsing techniques. + +Fields tend to overlap with each other, and algorithm advances in one field may improve those of other, sometimes completely unrelated, fields. For example, dynamic programming was invented for optimization of resource consumption in industry but is now used in solving a broad range of problems in many fields. + +By complexity + +Algorithms can be classified by the amount of time they need to complete compared to their input size: + Constant time: if the time needed by the algorithm is the same, regardless of the input size. E.g. an access to an array element. + Logarithmic time: if the time is a logarithmic function of the input size. E.g. binary search algorithm. + Linear time: if the time is proportional to the input size. E.g. the traverse of a list. + Polynomial time: if the time is a power of the input size. E.g. the bubble sort algorithm has quadratic time complexity. + Exponential time: if the time is an exponential function of the input size. E.g. Brute-force search. + +Some problems may have multiple algorithms of differing complexity, while other problems might have no algorithms or no known efficient algorithms. There are also mappings from some problems to other problems. Owing to this, it was found to be more suitable to classify the problems themselves instead of the algorithms into equivalence classes based on the complexity of the best possible algorithms for them. + +Continuous algorithms +The adjective "continuous" when applied to the word "algorithm" can mean: + An algorithm operating on data that represents continuous quantities, even though this data is represented by discrete approximations—such algorithms are studied in numerical analysis; or + An algorithm in the form of a differential equation that operates continuously on the data, running on an analog computer. + +Algorithm = Logic + Control +In logic programming, algorithms are viewed as having both "a logic component, which specifies the knowledge to be used in solving problems, and a control component, which determines the problem-solving strategies by means of which that knowledge is used." + +The Euclidean algorithm illustrates this view of an algorithm. Here is a logic programming representation, using :- to represent "if", and the relation gcd(A, B, C) to represent the function gcd(A, B) = C: +gcd(A, A, A). +gcd(A, B, C) :- A > B, gcd(A-B, B, C). +gcd(A, B, C) :- B > A, gcd(A, B-A, C). + +In the logic programming language Ciao the gcd relation can be represented directly in functional notation: +gcd(A, A) := A. +gcd(A, B) := gcd(A-B, B) :- A > B. +gcd(A, B) := gcd(A, B-A) :- B > A. + +The Ciao implementation translates the functional notation into a relational representation in Prolog, extracting the embedded subtractions, A-B and B-A, as separate conditions: +gcd(A, A, A). +gcd(A, B, C) :- A > B, A' is A-B, gcd(A', B, C). +gcd(A, B, C) :- B > A, B' is B-A, gcd(A, B, C). + +The resulting program has a purely logical (and "declarative") reading, as a recursive (or inductive) definition, which is independent of how the logic is used to solve problems: +The gcd of A and A is A. +The gcd of A and B is C, if A > B and A' is A-B and the gcd of A' and B is C. +The gcd of A and B is C, if B > A and B' is B-A and the gcd of A and B' is C. + +Different problem-solving strategies turn the logic into different algorithms. In theory, given a pair of integers A and B, forward (or "bottom-up") reasoning could be used to generate all instances of the gcd relation, terminating when the desired gcd of A and B is generated. Of course, forward reasoning is entirely useless in this case. But in other cases, such as the definition of the Fibonacci sequence and Datalog, forward reasoning can be an efficient problem solving strategy. (See for example the logic program for computing fibonacci numbers in Algorithm = Logic + Control). + +In contrast with the inefficiency of forward reasoning in this example, backward (or "top-down") reasoning using SLD resolution turns the logic into the Euclidean algorithm: +To find the gcd C of two given numbers A and B: +If A = B, then C = A. +If A > B, then let A' = A-B and find the gcd of A' and B, which is C. +If B > A, then let B' = B-A and find the gcd of A and B', which is C. + +One of the advantages of the logic programming representation of the algorithm is that its purely logical reading makes it easier to verify that the algorithm is correct relative to the standard non-recursive definition of gcd. Here is the standard definition written in Prolog: + +gcd(A, B, C) :- divides(C, A), divides(C, B), + forall((divides(D, A), divides(D, B)), D =< C). + + divides(C, Number) :- + between(1, Number, C), 0 is Number mod C. + +This definition, which is the specification of the Euclidean algorithm, is also executable in Prolog: Backward reasoning treats the specification as the brute-force algorithm that iterates through all of the integers C between 1 and A, checking whether C divides both A and B, and then for each such C iterates again through all of the integers D between 1 and A, until it finds a C such that C is greater than or equal to all of the D that also divide both A and B. Although this algorithm is hopelessly inefficient, it shows that formal specifications can often be written in logic programming form, and they can be executed by Prolog, to check that they correctly represent informal requirements. + +Legal issues + +Algorithms, by themselves, are not usually patentable. In the United States, a claim consisting solely of simple manipulations of abstract concepts, numbers, or signals does not constitute "processes" (USPTO 2006), so algorithms are not patentable (as in Gottschalk v. Benson). However practical applications of algorithms are sometimes patentable. For example, in Diamond v. Diehr, the application of a simple feedback algorithm to aid in the curing of synthetic rubber was deemed patentable. The patenting of software is controversial, and there are criticized patents involving algorithms, especially data compression algorithms, such as Unisys's LZW patent. + +Additionally, some cryptographic algorithms have export restrictions (see export of cryptography). + +History: Development of the notion of "algorithm" + +Ancient Near East +The earliest evidence of algorithms is found in the Babylonian mathematics of ancient Mesopotamia (modern Iraq). A Sumerian clay tablet found in Shuruppak near Baghdad and dated to described the earliest division algorithm. During the Hammurabi dynasty , Babylonian clay tablets described algorithms for computing formulas. Algorithms were also used in Babylonian astronomy. Babylonian clay tablets describe and employ algorithmic procedures to compute the time and place of significant astronomical events. + +Algorithms for arithmetic are also found in ancient Egyptian mathematics, dating back to the Rhind Mathematical Papyrus . Algorithms were later used in ancient Hellenistic mathematics. Two examples are the Sieve of Eratosthenes, which was described in the Introduction to Arithmetic by Nicomachus, and the Euclidean algorithm, which was first described in Euclid's Elements (). + +Discrete and distinguishable symbols +Tally-marks: To keep track of their flocks, their sacks of grain and their money the ancients used tallying: accumulating stones or marks scratched on sticks or making discrete symbols in clay. Through the Babylonian and Egyptian use of marks and symbols, eventually Roman numerals and the abacus evolved (Dilson, p. 16–41). Tally marks appear prominently in unary numeral system arithmetic used in Turing machine and Post–Turing machine computations. + +Manipulation of symbols as "place holders" for numbers: algebra +Muhammad ibn Mūsā al-Khwārizmī, a Persian mathematician, wrote the Al-jabr in the 9th century. The terms "algorism" and "algorithm" are derived from the name al-Khwārizmī, while the term "algebra" is derived from the book Al-jabr. In Europe, the word "algorithm" was originally used to refer to the sets of rules and techniques used by Al-Khwarizmi to solve algebraic equations, before later being generalized to refer to any set of rules or techniques. This eventually culminated in Leibniz's notion of the calculus ratiocinator (): + +Cryptographic algorithms +The first cryptographic algorithm for deciphering encrypted code was developed by Al-Kindi, a 9th-century Arab mathematician, in A Manuscript On Deciphering Cryptographic Messages. He gave the first description of cryptanalysis by frequency analysis, the earliest codebreaking algorithm. + +Mechanical contrivances with discrete states +The clock: Bolter credits the invention of the weight-driven clock as "The key invention [of Europe in the Middle Ages]", in particular, the verge escapement that provides us with the tick and tock of a mechanical clock. "The accurate automatic machine" led immediately to "mechanical automata" beginning in the 13th century and finally to "computational machines"—the difference engine and analytical engines of Charles Babbage and Countess Ada Lovelace, mid-19th century. Lovelace is credited with the first creation of an algorithm intended for processing on a computer—Babbage's analytical engine, the first device considered a real Turing-complete computer instead of just a calculator—and is sometimes called "history's first programmer" as a result, though a full implementation of Babbage's second device would not be realized until decades after her lifetime. + +Logical machines 1870 – Stanley Jevons' "logical abacus" and "logical machine": The technical problem was to reduce Boolean equations when presented in a form similar to what is now known as Karnaugh maps. Jevons (1880) describes first a simple "abacus" of "slips of wood furnished with pins, contrived so that any part or class of the [logical] combinations can be picked out mechanically ... More recently, however, I have reduced the system to a completely mechanical form, and have thus embodied the whole of the indirect process of inference in what may be called a Logical Machine" His machine came equipped with "certain moveable wooden rods" and "at the foot are 21 keys like those of a piano [etc.] ...". With this machine he could analyze a "syllogism or any other simple logical argument". + +This machine he displayed in 1870 before the Fellows of the Royal Society. Another logician John Venn, however, in his 1881 Symbolic Logic, turned a jaundiced eye to this effort: "I have no high estimate myself of the interest or importance of what are sometimes called logical machines ... it does not seem to me that any contrivances at present known or likely to be discovered really deserve the name of logical machines"; see more at Algorithm characterizations. But not to be outdone he too presented "a plan somewhat analogous, I apprehend, to Prof. Jevon's abacus ... [And] [a]gain, corresponding to Prof. Jevons's logical machine, the following contrivance may be described. I prefer to call it merely a logical-diagram machine ... but I suppose that it could do very completely all that can be rationally expected of any logical machine". + +Jacquard loom, Hollerith punch cards, telegraphy and telephony – the electromechanical relay: Bell and Newell (1971) indicate that the Jacquard loom (1801), precursor to Hollerith cards (punch cards, 1887), and "telephone switching technologies" were the roots of a tree leading to the development of the first computers. By the mid-19th century the telegraph, the precursor of the telephone, was in use throughout the world, its discrete and distinguishable encoding of letters as "dots and dashes" a common sound. By the late 19th century the ticker tape () was in use, as was the use of Hollerith cards in the 1890 U.S. census. Then came the teleprinter () with its punched-paper use of Baudot code on tape. + +Telephone-switching networks of electromechanical relays (invented 1835) was behind the work of George Stibitz (1937), the inventor of the digital adding device. As he worked in Bell Laboratories, he observed the "burdensome' use of mechanical calculators with gears. "He went home one evening in 1937 intending to test his idea... When the tinkering was over, Stibitz had constructed a binary adding device". + +The mathematician Martin Davis observes the particular importance of the electromechanical relay (with its two "binary states" open and closed): + It was only with the development, beginning in the 1930s, of electromechanical calculators using electrical relays, that machines were built having the scope Babbage had envisioned." + +Mathematics during the 19th century up to the mid-20th century +Symbols and rules: In rapid succession, the mathematics of George Boole (1847, 1854), Gottlob Frege (1879), and Giuseppe Peano (1888–1889) reduced arithmetic to a sequence of symbols manipulated by rules. Peano's The principles of arithmetic, presented by a new method (1888) was "the first attempt at an axiomatization of mathematics in a symbolic language". + +But Heijenoort gives Frege (1879) this kudos: Frege's is "perhaps the most important single work ever written in logic. ... in which we see a formula language', that is a lingua characterica, a language written with special symbols, "for pure thought", that is, free from rhetorical embellishments ... constructed from specific symbols that are manipulated according to definite rules". The work of Frege was further simplified and amplified by Alfred North Whitehead and Bertrand Russell in their Principia Mathematica (1910–1913). + +The paradoxes: At the same time a number of disturbing paradoxes appeared in the literature, in particular, the Burali-Forti paradox (1897), the Russell paradox (1902–03), and the Richard Paradox. The resultant considerations led to Kurt Gödel's paper (1931)—he specifically cites the paradox of the liar—that completely reduces rules of recursion to numbers. + +Effective calculability: In an effort to solve the Entscheidungsproblem defined precisely by Hilbert in 1928, mathematicians first set about to define what was meant by an "effective method" or "effective calculation" or "effective calculability" (i.e., a calculation that would succeed). In rapid succession the following appeared: Alonzo Church, Stephen Kleene and J.B. Rosser's λ-calculus a finely honed definition of "general recursion" from the work of Gödel acting on suggestions of Jacques Herbrand (cf. Gödel's Princeton lectures of 1934) and subsequent simplifications by Kleene. Church's proof that the Entscheidungsproblem was unsolvable, Emil Post's definition of effective calculability as a worker mindlessly following a list of instructions to move left or right through a sequence of rooms and while there either mark or erase a paper or observe the paper and make a yes-no decision about the next instruction. Alan Turing's proof of that the Entscheidungsproblem was unsolvable by use of his "a- [automatic-] machine"—in effect almost identical to Post's "formulation", J. Barkley Rosser's definition of "effective method" in terms of "a machine". Kleene's proposal of a precursor to "Church thesis" that he called "Thesis I", and a few years later Kleene's renaming his Thesis "Church's Thesis" and proposing "Turing's Thesis". + +Emil Post (1936) and Alan Turing (1936–37, 1939) +Emil Post (1936) described the actions of a "computer" (human being) as follows: +"...two concepts are involved: that of a symbol space in which the work leading from problem to answer is to be carried out, and a fixed unalterable set of directions. + +His symbol space would be +"a two-way infinite sequence of spaces or boxes ... The problem solver or worker is to move and work in this symbol space, being capable of being in, and operating in but one box at a time. ... a box is to admit of but two possible conditions, i.e., being empty or unmarked, and having a single mark in it, say a vertical stroke. + +"One box is to be singled out and called the starting point. ... a specific problem is to be given in symbolic form by a finite number of boxes [i.e., INPUT] being marked with a stroke. Likewise, the answer [i.e., OUTPUT] is to be given in symbolic form by such a configuration of marked boxes... + +"A set of directions applicable to a general problem sets up a deterministic process when applied to each specific problem. This process terminates only when it comes to the direction of type (C ) [i.e., STOP]". See more at Post–Turing machine + +Alan Turing's work preceded that of Stibitz (1937); it is unknown whether Stibitz knew of the work of Turing. Turing's biographer believed that Turing's use of a typewriter-like model derived from a youthful interest: "Alan had dreamt of inventing typewriters as a boy; Mrs. Turing had a typewriter, and he could well have begun by asking himself what was meant by calling a typewriter 'mechanical. Given the prevalence at the time of Morse code, telegraphy, ticker tape machines, and teletypewriters, it is quite possible that all were influences on Turing during his youth. + +Turing—his model of computation is now called a Turing machine—begins, as did Post, with an analysis of a human computer that he whittles down to a simple set of basic motions and "states of mind". But he continues a step further and creates a machine as a model of computation of numbers. + +"Computing is normally done by writing certain symbols on paper. We may suppose this paper is divided into squares like a child's arithmetic book...I assume then that the computation is carried out on one-dimensional paper, i.e., on a tape divided into squares. I shall also suppose that the number of symbols which may be printed is finite... + +"The behavior of the computer at any moment is determined by the symbols which he is observing, and his "state of mind" at that moment. We may suppose that there is a bound B to the number of symbols or squares that the computer can observe at one moment. If he wishes to observe more, he must use successive observations. We will also suppose that the number of states of mind which need be taken into account is finite... + +"Let us imagine that the operations performed by the computer to be split up into 'simple operations' which are so elementary that it is not easy to imagine them further divided." + +Turing's reduction yields the following: +"The simple operations must therefore include: +"(a) Changes of the symbol on one of the observed squares +"(b) Changes of one of the squares observed to another square within L squares of one of the previously observed squares. +"It may be that some of these change necessarily invoke a change of state of mind. The most general single operation must, therefore, be taken to be one of the following: +"(A) A possible change (a) of symbol together with a possible change of state of mind. +"(B) A possible change (b) of observed squares, together with a possible change of state of mind" + +"We may now construct a machine to do the work of this computer." + +A few years later, Turing expanded his analysis (thesis, definition) with this forceful expression of it: +"A function is said to be "effectively calculable" if its values can be found by some purely mechanical process. Though it is fairly easy to get an intuitive grasp of this idea, it is nevertheless desirable to have some more definite, mathematical expressible definition ... [he discusses the history of the definition pretty much as presented above with respect to Gödel, Herbrand, Kleene, Church, Turing, and Post] ... We may take this statement literally, understanding by a purely mechanical process one which could be carried out by a machine. It is possible to give a mathematical description, in a certain normal form, of the structures of these machines. The development of these ideas leads to the author's definition of a computable function, and to an identification of computability † with effective calculability... +"† We shall use the expression "computable function" to mean a function calculable by a machine, and we let "effectively calculable" refer to the intuitive idea without particular identification with any one of these definitions". + +J. B. Rosser (1939) and S. C. Kleene (1943) +J. Barkley Rosser defined an "effective [mathematical] method" in the following manner (italicization added): +Effective method' is used here in the rather special sense of a method each step of which is precisely determined and which is certain to produce the answer in a finite number of steps. With this special meaning, three different precise definitions have been given to date. [his footnote #5; see discussion immediately below]. The simplest of these to state (due to Post and Turing) says essentially that an effective method of solving certain sets of problems exists if one can build a machine which will then solve any problem of the set with no human intervention beyond inserting the question and (later) reading the answer. All three definitions are equivalent, so it doesn't matter which one is used. Moreover, the fact that all three are equivalent is a very strong argument for the correctness of any one." (Rosser 1939:225–226) + +Rosser's footnote No. 5 references the work of (1) Church and Kleene and their definition of λ-definability, in particular, Church's use of it in his An Unsolvable Problem of Elementary Number Theory (1936); (2) Herbrand and Gödel and their use of recursion, in particular, Gödel's use in his famous paper On Formally Undecidable Propositions of Principia Mathematica and Related Systems I (1931); and (3) Post (1936) and Turing (1936–37) in their mechanism-models of computation. + +Stephen C. Kleene defined as his now-famous "Thesis I" known as the Church–Turing thesis. But he did this in the following context (boldface in original): +"12. Algorithmic theories... In setting up a complete algorithmic theory, what we do is to describe a procedure, performable for each set of values of the independent variables, which procedure necessarily terminates and in such manner that from the outcome we can read a definite answer, "yes" or "no," to the question, "is the predicate value true?"" (Kleene 1943:273) + +History after 1950 +A number of efforts have been directed toward further refinement of the definition of "algorithm", and activity is on-going because of issues surrounding, in particular, foundations of mathematics (especially the Church–Turing thesis) and philosophy of mind (especially arguments about artificial intelligence).

The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. + +Description +With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. + +One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, because their seed-to-seed life cycle is only weeks and they spend most of the year as seeds to survive dry conditions. + + +Cultivation +In cultivation, many food plants are, or are grown as, annuals, including virtually all domesticated grains. Some perennials and biennials are grown in gardens as annuals for convenience, particularly if they are not considered cold hardy for the local climate. Carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively. Tomato, sweet potato and bell pepper are tender perennials usually grown as annuals. Ornamental perennials commonly grown as annuals are impatiens, mirabilis, wax begonia, snapdragon, pelargonium, coleus and petunia. Examples of true annuals include corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia and marigold. + +Summer + +Summer annuals sprout, flower, produce seed, and die, during the warmer months of the year. + +The lawn weed crabgrass is a summer annual. + +Winter +Winter annuals germinate in autumn or winter, live through the winter, and then bloom in winter or spring. + +The plants grow and bloom during the cool season when most other plants are dormant or other annuals are in seed form waiting for warmer weather to germinate. Winter annuals die after flowering and setting seed. The seeds germinate in the autumn or winter when the soil temperature is cool. + +Winter annuals typically grow low to the ground, where they are usually sheltered from the coldest nights by snow cover, and make use of warm periods in winter for growth when the snow melts. Some common winter annuals include henbit, deadnettle, chickweed, and winter cress. + +Winter annuals are important ecologically, as they provide vegetative cover that prevents soil erosion during winter and early spring when no other cover exists and they provide fresh vegetation for animals and birds that feed on them. Although they are often considered to be weeds in gardens, this viewpoint is not always necessary, as most of them die when the soil temperature warms up again in early to late spring when other plants are still dormant and have not yet leafed out. + +Even though they do not compete directly with cultivated plants, sometimes winter annuals are considered a pest in commercial agriculture, because they can be hosts for insect pests or fungal diseases (such as ovary smut, Microbotryum sp.) which attack crops being cultivated. The property that prevents the soil from drying out can also be problematic for commercial agriculture. + +Molecular genetics +In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to its conversion into a perennial plant. Researchers deactivated the SOC1 and FUL genes (which control flowering time) of Arabidopsis thaliana. This switch established phenotypes common in perennial plants, such as wood formation. + +See also + + - Plant that flowers & sets seeds once, then dies. +Ephemeral plant + +References + +External links + + +Garden plants +The anthophytes are a paraphyletic grouping of plant taxa bearing flower-like reproductive structures. The group, once thought to be a clade, contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales. + +Detailed morphological and molecular studies have shown that the group is not actually monophyletic, with proposed floral homologies of the gnetophytes and the angiosperms having evolved in parallel. This makes it easier to reconcile molecular clock data that suggests that the angiosperms diverged from the gymnosperms around 320-300 mya. + +Some more recent studies have used the word anthophyte to describe a hypothetical group which includes the angiosperms and a variety of extinct seed plant groups (with various suggestions including at least some of the following groups: glossopterids, corystosperms, Petriellales Pentoxylales, Bennettitales and Caytoniales), but not the Gnetales. + +References + +Historically recognized plant taxa +An atlas is a collection of maps. + +Atlas may also refer to: + +Mythology + Atlas (mythology), an Ancient Greek Titanic deity + Atlas, the first legendary king of Atlantis + Atlas of Mauretania, a legendary king + +Places + +United States + Atlas, California + Atlas, Illinois + Atlas, Texas + Atlas, West Virginia + Atlas, Wisconsin + Atlas District, in Washington, D.C. + Atlas Peak AVA, a California wine region + Atlas Township, Michigan + +Other places + Atlas Cinema, a historic movie theatre in Istanbul, Turkey + Atlas Mountains, a set of mountain ranges in northwestern Africa + Atlas, Nilüfer, a village in Bursa Province, Turkey + +People with the name + Atlas (given name) + Atlas (graffiti artist) + Atlas DaBone, American wrestler and football player + Charles Atlas (1892–1972), Italian-American bodybuilder + Charles Atlas (artist) + David Atlas (born 1924), American meteorologist + James Atlas (1949-2019), American writer, editor and publisher + Meir Atlas (1848–1926), Lithuanian rabbi + Natacha Atlas (born 1964), Belgian singer + Nava Atlas, American book artist and author + Omar Atlas (born 1938), former Venezuelan professional wrestler + Scott Atlas (born 1955), American conservative health care policy advisor + Teddy Atlas (born 1956), American boxing trainer and commentator + Tony Atlas (born 1954), American wrestler and bodybuilder + +Arts, entertainment, and media + +Comics + Atlas (comic book series), by Dylan Horrocks + Agents of Atlas, a Marvel Comics mini-series + Atlas Comics (1950s), a publisher + Atlas/Seaboard Comics, a 1970s line of comics + +Fictional characters + Atlas (DC Comics), any of several fictional characters + Atlas (Teen Titans) + Atlas, an Astro Boy (1980) character + Atlas (BioShock) + Atlas, a BattleMech in the BattleTech universe + Atlas, an antagonist in Mega Man ZX Advent + Atlas, a Portal 2 character + Atlas, a PS238 character + Erik Josten, a.k.a.

mouth bath is a liquid which is held in the mouth passively or swirled around the mouth by contraction of the perioral muscles and/or movement of the head, and may be gargled, where the head is tilted back and the liquid bubbled at the back of the mouth. + +Usually mouthwashes are antiseptic solutions intended to reduce the microbial load in the mouth, although other mouthwashes might be given for other reasons such as for their analgesic, anti-inflammatory or anti-fungal action. Additionally, some rinses act as saliva substitutes to neutralize acid and keep the mouth moist in xerostomia (dry mouth). Cosmetic mouthrinses temporarily control or reduce bad breath and leave the mouth with a pleasant taste. + +Rinsing with water or mouthwash after brushing with a fluoride toothpaste can reduce the availability of salivary fluoride. This can lower the anti-cavity re-mineralization and antibacterial effects of fluoride. Fluoridated mouthwash may mitigate this effect or in high concentrations increase available fluoride, but is not as cost-effective as leaving the fluoride toothpaste on the teeth after brushing. A group of experts discussing post brushing rinsing in 2012 found that although there was clear guidance given in many public health advice publications to "spit, avoid rinsing with water/excessive rinsing with water" they believed there was a limited evidence base for best practice. + +Use +Common use involves rinsing the mouth with about 20–50 ml (2/3 fl oz) of mouthwash. The wash is typically swished or gargled for about half a minute and then spat out. Most companies suggest not drinking water immediately after using mouthwash. In some brands, the expectorate is stained, so that one can see the bacteria and debris. +Mouthwash should not be used immediately after brushing the teeth so as not to wash away the beneficial fluoride residue left from the toothpaste. Similarly, the mouth should not be rinsed out with water after brushing. Patients were told to "spit don't rinse" after toothbrushing as part of a National Health Service campaign in the UK. A fluoride mouthrinse can be used at a different time of the day to brushing. + +Gargling is where the head is tilted back, allowing the mouthwash to sit in the back of the mouth while exhaling, causing the liquid to bubble. Gargling is practiced in Japan for perceived prevention of viral infection. One commonly used way is with infusions or tea. In some cultures, gargling is usually done in private, typically in a bathroom at a sink so the liquid can be rinsed away. + +Dangerous misuse +If one drinks mouthwash, serious harm and even death can quickly result from the high alcohol content and other harmful substances in mouthwash. It is a common cause of death among homeless people during winter months, because a person can feel warmer after drinking it. + +Effects +The most-commonly-used mouthwashes are commercial antiseptics, which are used at home as part of an oral hygiene routine. Mouthwashes combine ingredients to treat a variety of oral conditions. Variations are common, and mouthwash has no standard formulation, so its use and recommendation involves concerns about patient safety. Some manufacturers of mouthwash state that their antiseptic and antiplaque mouthwashes kill the bacterial plaque that causes cavities, gingivitis, and bad breath. It is, however, generally agreed that the use of mouthwash does not eliminate the need for both brushing and flossing. The American Dental Association asserts that regular brushing and proper flossing are enough in most cases, in addition to regular dental check-ups, although they approve many mouthwashes. +For many patients, however, the mechanical methods could be tedious and time-consuming, and, additionally, some local conditions may render them especially difficult. Chemotherapeutic agents, including mouthwashes, could have a key role as adjuncts to daily home care, preventing and controlling supragingival plaque, gingivitis and oral malodor. + +Minor and transient side effects of mouthwashes are very common, such as taste disturbance, tooth staining, sensation of a dry mouth, etc. Alcohol-containing mouthwashes may make dry mouth and halitosis worse, as they dry out the mouth. Soreness, ulceration and redness may sometimes occur (e.g., aphthous stomatitis or allergic contact stomatitis) if the person is allergic or sensitive to mouthwash ingredients, such as preservatives, coloring, flavors and fragrances. Such effects might be reduced or eliminated by diluting the mouthwash with water, using a different mouthwash (e.g. saltwater), or foregoing mouthwash entirely. + +Prescription mouthwashes are used prior to and after oral surgery procedures, such as tooth extraction, or to treat the pain associated with mucositis caused by radiation therapy or chemotherapy. They are also prescribed for aphthous ulcers, other oral ulcers, and other mouth pain. "Magic mouthwashes" are prescription mouthwashes compounded in a pharmacy from a list of ingredients specified by a doctor. Despite a lack of evidence that prescription mouthwashes are more effective in decreasing the pain of oral lesions, many patients and prescribers continue to use them. There has been only one controlled study to evaluate the efficacy of magic mouthwash; it shows no difference in efficacy between the most common magic-mouthwash formulation, on the one hand, and commercial mouthwashes (such as chlorhexidine) or a saline/baking soda solution, on the other. Current guidelines suggest that saline solution is just as effective as magic mouthwash in pain relief and in shortening the healing time of oral mucositis from cancer therapies. + +History + +The first known references to mouth rinsing is in Ayurveda for treatment of gingivitis. Later, in the Greek and Roman periods, mouth rinsing following mechanical cleansing became common among the upper classes, and Hippocrates recommended a mixture of salt, alum, and vinegar. The Jewish Talmud, dating back about 1,800 years, suggests a cure for gum ailments containing "dough water" and olive oil. The ancient Chinese had also gargled salt water, tea and wine as a form of mouthwash after meals, due to the antiseptic properties of those liquids. + +Before Europeans came to the Americas, Native North American and Mesoamerican cultures used mouthwashes, often made from plants such as Coptis trifolia. Indeed, Aztec dentistry was more advanced than European dentistry of the age. Peoples of the Americas used salt water mouthwashes for sore throats, and other mouthwashes for problems such as teething and mouth ulcers. + +Anton van Leeuwenhoek, the famous 17th century microscopist, discovered living organisms (living, because they were mobile) in deposits on the teeth (what we now call dental plaque). He also found organisms in water from the canal next to his home in Delft. He experimented with samples by adding vinegar or brandy and found that this resulted in the immediate immobilization or killing of the organisms suspended in water. Next he tried rinsing the mouth of himself and somebody else with a mouthwash containing vinegar or brandy and found that living organisms remained in the dental plaque. He concluded—correctly—that the mouthwash either did not reach, or was not present long enough, to kill the plaque organisms. +In 1892, German Richard Seifert invented mouthwash product Odol, which was produced by company founder Karl August Lingner (1861–1916) in Dresden. + +That remained the state of affairs until the late 1960s when Harald Loe (at the time a professor at the Royal Dental College in Aarhus, Denmark) demonstrated that a chlorhexidine compound could prevent the build-up of dental plaque. The reason for chlorhexidine's effectiveness is that it strongly adheres to surfaces in the mouth and thus remains present in effective concentrations for many hours. + +Since then commercial interest in mouthwashes has been intense and several newer products claim effectiveness in reducing the build-up in dental plaque and the associated severity of gingivitis, in addition to fighting bad breath. Many of these solutions aim to control the volatile sulfur compound–creating anaerobic bacteria that live in the mouth and excrete substances that lead to bad breath and unpleasant mouth taste. For example, the number of mouthwash variants in the United States of America has grown from 15 (1970) to 66 (1998) to 113 (2012). + +Research +Research in the field of microbiotas shows that only a limited set of microbes cause tooth decay, with most of the bacteria in the human mouth being harmless. Focused attention on cavity-causing bacteria such as Streptococcus mutans has led research into new mouthwash treatments that prevent these bacteria from initially growing. While current mouthwash treatments must be used with a degree of frequency to prevent this bacteria from regrowing, future treatments could provide a viable long-term solution. + +A clinical trial and laboratory studies have shown that alcohol-containing mouthwash could reduce the growth of Neisseria gonorrhoeae in the pharynx. However, subsequent trials have found that there was no difference in gonorrhoea cases among men using daily mouthwash compared to those who did not use mouthwash for 12 weeks. + +Ingredients + +Alcohol + +Alcohol is added to mouthwash not to destroy bacteria but to act as a carrier agent for essential active ingredients such as menthol, eucalyptol and thymol, which help to penetrate plaque. Sometimes a significant amount of alcohol (up to 27% vol) is added, as a carrier for the flavor, to provide "bite". Because of the alcohol content, it is possible to fail a breathalyzer test after rinsing, although breath alcohol levels return to normal after 10 minutes. In addition, alcohol is a drying agent, which encourages bacterial activity in the mouth, releasing more malodorous volatile sulfur compounds. Therefore, alcohol-containing mouthwash may temporarily worsen halitosis in those who already have it, or, indeed, be the sole cause of halitosis in other individuals. + +It is hypothesized that alcohol in mouthwashes acts as a carcinogen (cancer-inducing agent). Generally, there is no scientific consensus about this. One review stated: + +The same researchers also state that the risk of acquiring oral cancer rises almost five times for users of alcohol-containing mouthwash who neither smoke nor drink (with a higher rate of increase for those who do). In addition, the authors highlight side effects from several mainstream mouthwashes that included dental erosion and accidental poisoning of children. The review garnered media attention and conflicting opinions from other researchers. Yinka Ebo of Cancer Research UK disputed the findings, concluding that "there is still not enough evidence to suggest that using mouthwash that contains alcohol will increase the risk of mouth cancer". Studies conducted in 1985, 1995, 2003, and 2012 did not support an association between alcohol-containing mouth rinses and oral cancer. Andrew Penman, chief executive of The Cancer Council New South Wales, called for further research on the matter. In a March 2009 brief, the American Dental Association said "the available evidence does not support a connection between oral cancer and alcohol-containing mouthrinse". Many newer brands of mouthwash are alcohol-free, not just in response to consumer concerns about oral cancer, but also to cater for religious groups who abstain from alcohol consumption. + +Benzydamine (analgesic) +In painful oral conditions such as aphthous stomatitis, analgesic mouthrinses (e.g. benzydamine mouthwash, or "Difflam") are sometimes used to ease pain, commonly used before meals to reduce discomfort while eating. + +Benzoic acid +Benzoic acid acts as a buffer. + +Betamethasone +Betamethasone is sometimes used as an anti-inflammatory, corticosteroid mouthwash. It may be used for severe inflammatory conditions of the oral mucosa such as the severe forms of aphthous stomatitis. + +Cetylpyridinium chloride (antiseptic, antimalodor) +Cetylpyridinium chloride containing mouthwash (e.g. 0.05%) is used in some specialized mouthwashes for halitosis. Cetylpyridinium chloride mouthwash has less anti-plaque effect than chlorhexidine and may cause staining of teeth, or sometimes an oral burning sensation or ulceration. + +Chlorhexidine digluconate and hexetidine (antiseptic) +Chlorhexidine digluconate is a chemical antiseptic and is used in a 0.05–0.2% solution as a mouthwash. There is no evidence to support that higher concentrations are more effective in controlling dental plaque and gingivitis. A randomized clinical trial conducted in Rabat University in Morocco found better results in plaque inhibition when chlorohexidine with alcohol base 0.12% was used, when compared to an alcohol-free 0.1% chlorhexidine mouthrinse. + +Chlorhexidine has good substantivity (the ability of a mouthwash to bind to hard and soft tissues in the mouth). It has anti-plaque action, and also some anti-fungal action. It is especially effective against Gram-negative rods. The proportion of Gram-negative rods increase as gingivitis develops, so it is also used to reduce gingivitis. It is sometimes used as an adjunct to prevent dental caries and to treat periodontal disease, although it does not penetrate into periodontal pockets well. Chlorhexidine mouthwash alone is unable to prevent plaque, so it is not a substitute for regular toothbrushing and flossing. Instead, chlorhexidine mouthwash is more effective when used as an adjunctive treatment with toothbrushing and flossing. In the short term, if toothbrushing is impossible due to pain, as may occur in primary herpetic gingivostomatitis, chlorhexidine mouthwash is used as a temporary substitute for other oral hygiene measures. It is not suited for use in acute necrotizing ulcerative gingivitis, however. Rinsing with chlorhexidine mouthwash before and after a tooth extraction may reduce the risk of a dry socket. Other uses of chlorhexidine mouthwash include prevention of oral candidiasis in immunocompromised persons, treatment of denture-related stomatitis, mucosal ulceration/erosions and oral mucosal lesions, general burning sensation and many other uses. + +Chlorhexidine mouthwash is known to have minor adverse effects. Chlorhexidine binds to tannins, meaning that prolonged use in persons who consume coffee, tea or red wine is associated with extrinsic staining (i.e. removable staining) of teeth. A systematic review of commercial chlorhexidine products with anti-discoloration systems (ADSs) found that the ADSs were able to reduce tooth staining without affecting the beneficial effects of chlorhexidine. Chlorhexidine mouthwash can also cause taste disturbance or alteration. Chlorhexidine is rarely associated with other issues like overgrowth of enterobacteria in persons with leukemia, desquamation, irritation, and stomatitis of oral mucosa, salivary gland pain and swelling, and hypersensitivity reactions including anaphylaxis. + +Hexetidine also has anti-plaque, analgesic, astringent and anti-malodor properties, but is considered an inferior alternative to chlorhexidine. + +Edible oils +In traditional Ayurvedic medicine, the use of oil mouthwashes is called "Kavala" ("oil swishing") or "Gandusha", and this practice has more recently been re-marketed by the complementary and alternative medicine industry as "oil pulling". Its promoters claim it works by "pulling out" "toxins", which are known as ama in Ayurvedic medicine, and thereby reducing inflammation. Ayurvedic literature claims that oil pulling is capable of improving oral and systemic health, including a benefit in conditions such as headaches, migraines, diabetes mellitus, asthma, and acne, as well as whitening teeth. + +Oil pulling has received little study and there is little evidence to support claims made by the technique's advocates. When compared with chlorhexidine in one small study, it was found to be less effective at reducing oral bacterial load, and the other health claims of oil pulling have failed scientific verification or have not been investigated. There is a report of lipid pneumonia caused by accidental inhalation of the oil during oil pulling. + +The mouth is rinsed with approximately one tablespoon of oil for 10–20 minutes then spat out. Sesame oil, coconut oil and ghee are traditionally used, but newer oils such as sunflower oil are also used. + +Essential oils +Phenolic compounds and monoterpenes include essential oil constituents that have some antibacterial properties, such as eucalyptol, eugenol, hinokitiol, menthol, phenol, or thymol. +Essential oils are oils which have been extracted from plants. Mouthwashes based on essential oils could be more effective than traditional mouthcare as anti-gingival treatments. They have been found effective in reducing halitosis, and are being used in several commercial mouthwashes. + +Fluoride (anticavity) +Anti-cavity mouthwashes use sodium fluoride to protect against tooth decay. Fluoride-containing mouthwashes are used as prevention for dental caries for individuals who are considered at higher risk for tooth decay, whether due to xerostomia related to salivary dysfunction or side effects of medication, to not drinking fluoridated water, or to being physically unable to care for their oral needs (brushing and flossing), and as treatment for those with dentinal hypersensitivity, gingival recession/ root exposure. + +Flavoring agents and Xylitol +Flavoring agents include sweeteners such as sorbitol, sucralose, sodium saccharin, and xylitol, which stimulate salivary function due to their sweetness and taste and helps restore the mouth to a neutral level of acidity. + +Xylitol rinses double as a bacterial inhibitor, and have been used as substitute for alcohol to avoid dryness of mouth associated with alcohol. + +Hydrogen peroxide +Hydrogen peroxide can be used as an oxidizing mouthwash (e.g. Peroxyl, 1.5%). It kills anaerobic bacteria, and also has a mechanical cleansing action when it froths as it comes into contact with debris in mouth. It is often used in the short term to treat acute necrotising ulcerative gingivitis. Side effects can occur with prolonged use, including hypertrophy of the lingual papillae. + +Lactoperoxidase (saliva substitute) +Enzymes and non-enzymatic proteins, such as lactoperoxidase, lysozyme, and lactoferrin, have been used in mouthwashes (e.g., Biotene) to reduce levels of oral bacteria, and, hence, of the acids produced by these bacteria. + +Lidocaine/xylocaine +Oral lidocaine is useful for the treatment of mucositis symptoms (inflammation of mucous membranes) induced by radiation or chemotherapy. There is evidence that lidocaine anesthetic mouthwash has the potential to be systemically absorbed, when it was tested in patients with oral mucositis who underwent a bone marrow transplant. + +Methyl salicylate +Methyl salicylate functions as an antiseptic, antiinflammatory, and analgesic agent, a flavoring, and a fragrance. Methyl salicylate has some anti-plaque action, but less than chlorhexidine. Methyl salicylate does not stain teeth. + +Nystatin +Nystatin suspension is an antifungal ingredient used for the treatment of oral candidiasis. + +Potassium oxalate +A randomized clinical trial found promising results in controlling and reducing dentine hypersensitivity when potassium oxalate mouthwash was used in conjugation with toothbrushing. + +Povidone/iodine (PVP-I) +A 2005 study found that gargling three times a day with simple water or with a povidone-iodine solution was effective in preventing upper respiratory infection and decreasing the severity of symptoms if contracted. Other sources attribute the benefit to a simple placebo effect. + +PVP-I in general covers "a wider virucidal spectrum, covering both enveloped and nonenveloped viruses, than the other commercially available antiseptics", which also includes the novel SARS-CoV-2 Virus. + +Sanguinarine +Sanguinarine-containing mouthwashes are marketed as anti-plaque and anti-malodor treatments. Sanguinarine is a toxic alkaloid herbal extract, obtained from plants such as Sanguinaria canadensis (bloodroot), Argemone mexicana (Mexican prickly poppy), and others. However, its use is strongly associated with the development of leukoplakia (a white patch in the mouth), usually in the buccal sulcus. This type of leukoplakia has been termed "sanguinaria-associated keratosis", and more than 80% of people with leukoplakia in the vestibule of the mouth have used this substance. Upon stopping contact with the causative substance, the lesions may persist for years. Although this type of leukoplakia may show dysplasia, the potential for malignant transformation is unknown. Ironically, elements within the complementary and alternative medicine industry promote the use of sanguinaria as a therapy for cancer. + +Sodium bicarbonate (baking soda) +Sodium bicarbonate is sometimes combined with salt to make a simple homemade mouthwash, indicated for any of the reasons that a saltwater mouthwash might be used. Pre-mixed mouthwashes of 1% sodium bicarbonate and 1.5% sodium chloride in aqueous solution are marketed, although pharmacists will easily be able to produce such a formulation from the base ingredients when required. Sodium bicarbonate mouthwash is sometimes used to remove viscous saliva and to aid visualization of the oral tissues during examination of the mouth. + +Sodium chloride (salt) + +Saline has a mechanical cleansing action and an antiseptic action, as it is a hypertonic solution in relation to bacteria, which undergo lysis. The heat of the solution produces a therapeutic increase in blood flow (hyperemia) to the surgical site, promoting healing. Hot saltwater mouthwashes also encourage the draining of pus from dental abscesses. In contrast, if heat is applied on the side of the face (e.g., hot water bottle) rather than inside the mouth, it may cause a dental abscess to drain extra-orally, which is later associated with an area of fibrosis on the face (see cutaneous sinus of dental origin). + +Saltwater mouthwashes are also routinely used after oral surgery, to keep food debris out of healing wounds and to prevent infection. Some oral surgeons consider saltwater mouthwashes the mainstay of wound cleanliness after surgery. In dental extractions, hot saltwater mouthbaths should start about 24 hours after a dental extraction. The term mouth bath implies that the liquid is passively held in the mouth, rather than vigorously swilled around (which could dislodge a blood clot). Once the blood clot has stabilized, the mouthwash can be used more vigorously. These mouthwashes tend to be advised for use about 6 times per day, especially after meals (to remove food from the socket). + +Sodium lauryl sulfate (foaming agent) +Sodium lauryl sulfate (SLS) is used as a foaming agent in many oral hygiene products, including many mouthwashes. Some may suggest that it is probably advisable to use mouthwash at least an hour after brushing with toothpaste when the toothpaste contains SLS, since the anionic compounds in the SLS toothpaste can deactivate cationic agents present in the mouthwash. + +Sucralfate +Sucralfate is a mucosal coating agent, composed of an aluminum salt of sulfated sucrose. It is not recommended for use in the prevention of oral mucositis in head and neck cancer patients receiving radiotherapy or chemoradiation, due to a lack of efficacy found in a well-designed, randomized controlled trial. + +Tetracycline (antibiotic) +Tetracycline is an antibiotic which may sometimes be used as a mouthwash in adults (it causes red staining of teeth in children). It is sometimes use for herpetiforme ulceration (an uncommon type of aphthous stomatitis), but prolonged use may lead to oral candidiasis, as the fungal population of the mouth overgrows in the absence of enough competing bacteria. Similarly, minocycline mouthwashes of 0.5% concentrations can relieve symptoms of recurrent aphthous stomatitis. Erythromycin is similar. + +Tranexamic acid +A 4.8% tranexamic acid solution is sometimes used as an antifibrinolytic mouthwash to prevent bleeding during and after oral surgery in persons with coagulopathies (clotting disorders) or who are taking anticoagulants (blood thinners such as warfarin). + +Triclosan +Triclosan is a non-ionic chlorinate bisphenol antiseptic found in some mouthwashes. When used in mouthwash (e.g. 0.03%), there is moderate substantivity, broad spectrum anti-bacterial action, some anti-fungal action, and significant anti-plaque effect, especially when combined with a copolymer or zinc citrate. Triclosan does not cause staining of the teeth. The safety of triclosan has been questioned. + +Zinc +Astringents like zinc chloride provide a pleasant-tasting sensation and shrink tissues. Zinc, when used in combination with other antiseptic agents, can limit the buildup of tartar. + +See also + Sodium fluoride/malic acid + Virucide + +References + +External links + Article on Bad-Breath Prevention Products – from MSNBC + Mayo Clinic Q&A on Magic Mouthwash for chemotherapy sores + American Dental Association article on mouthwash + +Dentifrices +Oral hygiene +Drug delivery devices +Dosage forms +Alexander III of Macedon (; 20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great, was a king of the ancient Greek kingdom of Macedon. He succeeded his father Philip II to the throne in 336 BC at the age of 20, and spent most of his ruling years conducting a lengthy military campaign throughout Western Asia and Egypt. By the age of 30, he had created one of the largest empires in history, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered to be one of history's greatest and most successful military commanders. + +Until the age of 16, Alexander was tutored by Aristotle. In 335 BC, shortly after his assumption of kingship over Macedon, he campaigned in the Balkans and reasserted control over Thrace and parts of Illyria before marching on the city of Thebes, which was subsequently destroyed in battle. Alexander then led the League of Corinth, and used his authority to launch the pan-Hellenic project envisaged by his father, assuming leadership over all Greeks in their conquest of Persia. + +In 334 BC, he invaded the Achaemenid Persian Empire and began a series of campaigns that lasted for 10 years. Following his conquest of Asia Minor, Alexander broke the power of Achaemenid Persia in a series of decisive battles, including those at Issus and Gaugamela; he subsequently overthrew Darius III and conquered the Achaemenid Empire in its entirety. After the fall of Persia, the Macedonian Empire held a vast swath of territory between the Adriatic Sea and the Indus River. Alexander endeavored to reach the "ends of the world and the Great Outer Sea" and invaded India in 326 BC, achieving an important victory over Porus, an ancient Indian king of present-day Punjab, at the Battle of the Hydaspes. Due to the demand of his homesick troops, he eventually turned back at the Beas River and later died in 323 BC in Babylon, the city of Mesopotamia that he had planned to establish as his empire's capital. Alexander's death left unexecuted an additional series of planned military and mercantile campaigns that would have begun with a Greek invasion of Arabia. In the years following his death, a series of civil wars broke out across the Macedonian Empire, eventually leading to its disintegration at the hands of the Diadochi. + +With his death marking the start of the Hellenistic period, Alexander's legacy includes the cultural diffusion and syncretism that his conquests engendered, such as Greco-Buddhism and Hellenistic Judaism. He founded more than twenty cities, with the most prominent being the city of Alexandria in Egypt. Alexander's settlement of Greek colonists and the resulting spread of Greek culture led to the overwhelming dominance of Hellenistic civilization and influence as far east as the Indian subcontinent. The Hellenistic period developed through the Roman Empire into modern Western culture; the Greek language became the lingua franca of the region and was the predominant language of the Byzantine Empire up until its collapse in the mid-15th century AD. Greek-speaking communities in central Anatolia and in far-eastern Anatolia survived until the Greek genocide and Greek–Turkish population exchanges of the early 20th century AD. Alexander became legendary as a classical hero in the mould of Achilles, featuring prominently in the historical and mythical traditions of both Greek and non-Greek cultures. His military achievements and unprecedented enduring successes in battle made him the measure against which many later military leaders would compare themselves, and his tactics remain a significant subject of study in military academies worldwide. + +Early life + +Lineage and childhood + +Alexander III was born in Pella, the capital of the Kingdom of Macedon, on the sixth day of the ancient Greek month of Hekatombaion, which probably corresponds to 20 July 356 BC (although the exact date is uncertain). He was the son of the erstwhile king of Macedon, Philip II, and his fourth wife, Olympias (daughter of Neoptolemus I, king of Epirus). Although Philip had seven or eight wives, Olympias was his principal wife for some time, likely because she gave birth to Alexander. + +Several legends surround Alexander's birth and childhood. According to the ancient Greek biographer Plutarch, on the eve of the consummation of her marriage to Philip, Olympias dreamed that her womb was struck by a thunderbolt that caused a flame to spread "far and wide" before dying away. Sometime after the wedding, Philip is said to have seen himself, in a dream, securing his wife's womb with a seal engraved with a lion's image. Plutarch offered a variety of interpretations for these dreams: that Olympias was pregnant before her marriage, indicated by the sealing of her womb; or that Alexander's father was Zeus. Ancient commentators were divided about whether the ambitious Olympias promulgated the story of Alexander's divine parentage, variously claiming that she had told Alexander, or that she dismissed the suggestion as impious. + +On the day Alexander was born, Philip was preparing a siege on the city of Potidea on the peninsula of Chalcidice. That same day, Philip received news that his general Parmenion had defeated the combined Illyrian and Paeonian armies and that his horses had won at the Olympic Games. It was also said that on this day, the Temple of Artemis in Ephesus, one of the Seven Wonders of the World, burnt down. This led Hegesias of Magnesia to say that it had burnt down because Artemis was away, attending the birth of Alexander. Such legends may have emerged when Alexander was king, and possibly at his instigation, to show that he was superhuman and destined for greatness from conception. + +In his early years, Alexander was raised by a nurse, Lanike, sister of Alexander's future general Cleitus the Black. Later in his childhood, Alexander was tutored by the strict Leonidas, a relative of his mother, and by Lysimachus of Acarnania. Alexander was raised in the manner of noble Macedonian youths, learning to read, play the lyre, ride, fight, and hunt. +When Alexander was ten years old, a trader from Thessaly brought Philip a horse, which he offered to sell for thirteen talents. The horse refused to be mounted, and Philip ordered it away. Alexander, however, detecting the horse's fear of its own shadow, asked to tame the horse, which he eventually managed. Plutarch stated that Philip, overjoyed at this display of courage and ambition, kissed his son tearfully, declaring: "My boy, you must find a kingdom big enough for your ambitions. Macedon is too small for you", and bought the horse for him. Alexander named it Bucephalas, meaning "ox-head". Bucephalas carried Alexander as far as India. When the animal died (because of old age, according to Plutarch, at age 30), Alexander named a city after him, Bucephala. + +Education + +When Alexander was 13, Philip began to search for a tutor, and considered such academics as Isocrates and Speusippus, the latter offering to resign from his stewardship of the Academy to take up the post. In the end, Philip chose Aristotle and provided the Temple of the Nymphs at Mieza as a classroom. In return for teaching Alexander, Philip agreed to rebuild Aristotle's hometown of Stageira, which Philip had razed, and to repopulate it by buying and freeing the ex-citizens who were slaves, or pardoning those who were in exile. + +Mieza was like a boarding school for Alexander and the children of Macedonian nobles, such as Ptolemy, Hephaistion, and Cassander. Many of these students would become his friends and future generals, and are often known as the "Companions". Aristotle taught Alexander and his companions about medicine, philosophy, morals, religion, logic, and art. Under Aristotle's tutelage, Alexander developed a passion for the works of Homer, and in particular the Iliad; Aristotle gave him an annotated copy, which Alexander later carried on his campaigns. + +Alexander was able to quote Euripides from memory. + +During his youth, Alexander was also acquainted with Persian exiles at the Macedonian court, who received the protection of Philip II for several years as they opposed Artaxerxes III. Among them were Artabazos II and his daughter Barsine, possible future mistress of Alexander, who resided at the Macedonian court from 352 to 342 BC, as well as Amminapes, future satrap of Alexander, or a Persian nobleman named Sisines. This gave the Macedonian court a good knowledge of Persian issues, and may even have influenced some of the innovations in the management of the Macedonian state. + +Suda writes that Anaximenes of Lampsacus was one of Alexander's teachers, and that Anaximenes also accompanied Alexander on his campaigns. + +Heir of Philip II + +Regency and ascent of Macedon + +At the age of 16, Alexander's education under Aristotle ended. Philip II had waged war against the Thracians to the north, which left Alexander in charge as regent and heir apparent. During Philip's absence, the Thracian tribe of Maedi revolted against Macedonia. Alexander responded quickly and drove them from their territory. The territory was colonized, and a city, named Alexandropolis, was founded. + +Upon Philip's return, Alexander was dispatched with a small force to subdue the revolts in southern Thrace. Campaigning against the Greek city of Perinthus, Alexander reportedly saved his father's life. Meanwhile, the city of Amphissa began to work lands that were sacred to Apollo near Delphi, a sacrilege that gave Philip the opportunity to further intervene in Greek affairs. While Philip was occupied in Thrace, Alexander was ordered to muster an army for a campaign in southern Greece. Concerned that other Greek states might intervene, Alexander made it look as though he was preparing to attack Illyria instead. During this turmoil, the Illyrians invaded Macedonia, only to be repelled by Alexander. + +Philip and his army joined his son in 338 BC, and they marched south through Thermopylae, taking it after stubborn resistance from its Theban garrison. They went on to occupy the city of Elatea, only a few days' march from both Athens and Thebes. The Athenians, led by Demosthenes, voted to seek alliance with Thebes against Macedonia. Both Athens and Philip sent embassies to win Thebes's favour, but Athens won the contest. Philip marched on Amphissa (ostensibly acting on the request of the Amphictyonic League), capturing the mercenaries sent there by Demosthenes and accepting the city's surrender. Philip then returned to Elatea, sending a final offer of peace to Athens and Thebes, who both rejected it. + +As Philip marched south, his opponents blocked him near Chaeronea, Boeotia. During the ensuing Battle of Chaeronea, Philip commanded the right wing and Alexander the left, accompanied by a group of Philip's trusted generals. According to the ancient sources, the two sides fought bitterly for some time. Philip deliberately commanded his troops to retreat, counting on the untested Athenian hoplites to follow, thus breaking their line. Alexander was the first to break the Theban lines, followed by Philip's generals. Having damaged the enemy's cohesion, Philip ordered his troops to press forward and quickly routed them. With the Athenians lost, the Thebans were surrounded. Left to fight alone, they were defeated. + +After the victory at Chaeronea, Philip and Alexander marched unopposed into the Peloponnese, welcomed by all cities; however, when they reached Sparta, they were refused, but did not resort to war. At Corinth, Philip established a "Hellenic Alliance" (modelled on the old anti-Persian alliance of the Greco-Persian Wars), which included most Greek city-states except Sparta. Philip was then named Hegemon (often translated as "Supreme Commander") of this league (known by modern scholars as the League of Corinth), and announced his plans to attack the Persian Empire. + +Exile and return +When Philip returned to Pella, he fell in love with and married Cleopatra Eurydice in 338 BC, the niece of his general Attalus. The marriage made Alexander's position as heir less secure, since any son of Cleopatra Eurydice would be a fully Macedonian heir, while Alexander was only half-Macedonian. During the wedding banquet, a drunken Attalus publicly prayed to the gods that the union would produce a legitimate heir. + +In 337 BC, Alexander fled Macedon with his mother, dropping her off with her brother, King Alexander I of Epirus in Dodona, capital of the Molossians. He continued to Illyria, where he sought refuge with one or more Illyrian kings, perhaps with Glaucias, and was treated as a guest, despite having defeated them in battle a few years before. However, it appears Philip never intended to disown his politically and militarily trained son. Accordingly, Alexander returned to Macedon after six months due to the efforts of a family friend, Demaratus, who mediated between the two parties. + +In the following year, the Persian satrap (governor) of Caria, Pixodarus, offered his eldest daughter to Alexander's half-brother, Philip Arrhidaeus. Olympias and several of Alexander's friends suggested this showed Philip intended to make Arrhidaeus his heir. Alexander reacted by sending an actor, Thessalus of Corinth, to tell Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander. When Philip heard of this, he stopped the negotiations and scolded Alexander for wishing to marry the daughter of a Carian, explaining that he wanted a better bride for him. Philip exiled four of Alexander's friends, Harpalus, Nearchus, Ptolemy and Erigyius, and had the Corinthians bring Thessalus to him in chains. + +King of Macedon + +Accession + +In summer 336 BC, while at Aegae attending the wedding of his daughter Cleopatra to Olympias's brother, Alexander I of Epirus, Philip was assassinated by the captain of his bodyguards, Pausanias. As Pausanias tried to escape, he tripped over a vine and was killed by his pursuers, including two of Alexander's companions, Perdiccas and Leonnatus. Alexander was proclaimed king on the spot by the nobles and army at the age of 20. + +Consolidation of power +Alexander began his reign by eliminating potential rivals to the throne. He had his cousin, the former Amyntas IV, executed. He also had two Macedonian princes from the region of Lyncestis killed for having been involved in his father's assassination, but spared a third, Alexander Lyncestes. Olympias had Cleopatra Eurydice, and Europa, her daughter by Philip, burned alive. When Alexander learned about this, he was furious. Alexander also ordered the murder of Attalus, who was in command of the advance guard of the army in Asia Minor and Cleopatra's uncle. + +Attalus was at that time corresponding with Demosthenes, regarding the possibility of defecting to Athens. Attalus also had severely insulted Alexander, and following Cleopatra's murder, Alexander may have considered him too dangerous to be left alive. Alexander spared Arrhidaeus, who was by all accounts mentally disabled, possibly as a result of poisoning by Olympias. + +News of Philip's death roused many states into revolt, including Thebes, Athens, Thessaly, and the Thracian tribes north of Macedon. When news of the revolts reached Alexander, he responded quickly. Though advised to use diplomacy, Alexander mustered 3,000 Macedonian cavalry and rode south towards Thessaly. He found the Thessalian army occupying the pass between Mount Olympus and Mount Ossa, and ordered his men to ride over Mount Ossa. When the Thessalians awoke the next day, they found Alexander in their rear and promptly surrendered, adding their cavalry to Alexander's force. He then continued south towards the Peloponnese. + +Alexander stopped at Thermopylae, where he was recognized as the leader of the Amphictyonic League before heading south to Corinth. Athens sued for peace and Alexander pardoned the rebels. The famous encounter between Alexander and Diogenes the Cynic occurred during Alexander's stay in Corinth. When Alexander asked Diogenes what he could do for him, the philosopher disdainfully asked Alexander to stand a little to the side, as he was blocking the sunlight. This reply apparently delighted Alexander, who is reported to have said "But verily, if I were not Alexander, I would like to be Diogenes." At Corinth, Alexander took the title of Hegemon ("leader") and, like Philip, was appointed commander for the coming war against Persia. He also received news of a Thracian uprising. + +Balkan campaign + +Before crossing to Asia, Alexander wanted to safeguard his northern borders. In the spring of 335 BC, he advanced to suppress several revolts. Starting from Amphipolis, he travelled east into the country of the "Independent Thracians"; and at Mount Haemus, the Macedonian army attacked and defeated the Thracian forces manning the heights. The Macedonians marched into the country of the Triballi, and defeated their army near the Lyginus river (a tributary of the Danube). Alexander then marched for three days to the Danube, encountering the Getae tribe on the opposite shore. Crossing the river at night, he surprised them and forced their army to retreat after the first cavalry skirmish. + +News then reached Alexander that the Illyrian chieftain Cleitus and King Glaukias of the Taulantii were in open revolt against his authority. Marching west into Illyria, Alexander defeated each in turn, forcing the two rulers to flee with their troops. With these victories, he secured his northern frontier. + +Destruction of Thebes + +While Alexander campaigned north, the Thebans and Athenians rebelled once again. Alexander immediately headed south. While the other cities again hesitated, Thebes decided to fight. The Theban resistance was ineffective, and Alexander razed the city and divided its territory between the other Boeotian cities. The end of Thebes cowed Athens, leaving all of Greece temporarily at peace. Alexander then set out on his Asian campaign, leaving Antipater as regent. + +Conquest of the Achaemenid Persian Empire + +Asia Minor + +After his victory at the Battle of Chaeronea (338 BC), Philip II began the work of establishing himself as hēgemṓn () of a league which according to Diodorus was to wage a campaign against the Persians for the sundry grievances Greece suffered in 480 and free the Greek cities of the western coast and islands from Achaemenid rule. In 336 he sent Parmenion, with Amyntas, Andromenes and Attalus, and an army of 10,000 men into Anatolia to make preparations for an invasion. At first, all went well. The Greek cities on the western coast of Anatolia revolted until the news arrived that Philip had been murdered and had been succeeded by his young son Alexander. The Macedonians were demoralized by Philip's death and were subsequently defeated near Magnesia by the Achaemenids under the command of the mercenary Memnon of Rhodes. + +Taking over the invasion project of Philip II, Alexander's army crossed the Hellespont in 334 BC with approximately 48,100 soldiers, 6,100 cavalry and a fleet of 120 ships with crews numbering 38,000, drawn from Macedon and various Greek city-states, mercenaries, and feudally raised soldiers from Thrace, Paionia, and Illyria. He showed his intent to conquer the entirety of the Persian Empire by throwing a spear into Asian soil and saying he accepted Asia as a gift from the gods. This also showed Alexander's eagerness to fight, in contrast to his father's preference for diplomacy. + +After an initial victory against Persian forces at the Battle of the Granicus, Alexander accepted the surrender of the Persian provincial capital and treasury of Sardis; he then proceeded along the Ionian coast, granting autonomy and democracy to the cities. Miletus, held by Achaemenid forces, required a delicate siege operation, with Persian naval forces nearby. Further south, at Halicarnassus, in Caria, Alexander successfully waged his first large-scale siege, eventually forcing his opponents, the mercenary captain Memnon of Rhodes and the Persian satrap of Caria, Orontobates, to withdraw by sea. Alexander left the government of Caria to a member of the Hecatomnid dynasty, Ada, who adopted Alexander. + +From Halicarnassus, Alexander proceeded into mountainous Lycia and the Pamphylian plain, asserting control over all coastal cities to deny the Persians naval bases. From Pamphylia onwards the coast held no major ports and Alexander moved inland. At Termessos, Alexander humbled but did not storm the Pisidian city. At the ancient Phrygian capital of Gordium, Alexander "undid" the hitherto unsolvable Gordian Knot, a feat said to await the future "king of Asia". According to the story, Alexander proclaimed that it did not matter how the knot was undone and hacked it apart with his sword. + +The Levant and Syria + +In spring 333 BC, Alexander crossed the Taurus into Cilicia. After a long pause due to an illness, he marched on towards Syria. Though outmanoeuvered by Darius's significantly larger army, he marched back to Cilicia, where he defeated Darius at Issus. Darius fled the battle, causing his army to collapse, and left behind his wife, his two daughters, his mother Sisygambis, and a fabulous treasure. He offered a peace treaty that included the lands he had already lost, and a ransom of 10,000 talents for his family. Alexander replied that since he was now king of Asia, it was he alone who decided territorial divisions. Alexander proceeded to take possession of Syria, and most of the coast of the Levant. In the following year, 332 BC, he was forced to attack Tyre, which he captured after a long and difficult siege. The men of military age were massacred and the women and children sold into slavery. + +Egypt + +When Alexander destroyed Tyre, most of the towns on the route to Egypt quickly capitulated. However, Alexander was met with resistance at Gaza. The stronghold was heavily fortified and built on a hill, requiring a siege. When "his engineers pointed out to him that because of the height of the mound it would be impossible... this encouraged Alexander all the more to make the attempt". After three unsuccessful assaults, the stronghold fell, but not before Alexander had received a serious shoulder wound. As in Tyre, men of military age were put to the sword and the women and children were sold into slavery. + +Egypt was only one of a large number of territories taken by Alexander from the Persians. After his trip to Siwa, Alexander was crowned in the temple of Ptah at Memphis. It appears that the Egyptian people did not find it disturbing that he was a foreigner - nor that he was absent for virtually his entire reign. Alexander restored the temples neglected by the Persians and dedicated new monuments to the Egyptian gods. In the temple of Luxor, near Karnak, he built a chapel for the sacred barge. During his brief months in Egypt, he reformed the taxation system on the Greek models and organized the military occupation of the country, but, early in 331 BC, he left for Asia in pursuit of the Persians. + +Alexander advanced on Egypt in later 332 BC, where he was regarded as a liberator. To legitimize taking power and be recognized as the descendant of the long line of pharaohs, Alexander made sacrifices to the gods at Memphis and went to consult the famous oracle of Amun-Ra at the Siwa Oasis in the Libyan desert, at which he was pronounced the son of the deity Amun. Henceforth, Alexander often referred to Zeus-Ammon as his true father, and after his death, currency depicted him adorned with the Horns of Ammon as a symbol of his divinity. The Greeks interpreted this message - one that the gods addressed to all pharaohs - as a prophecy. + +During his stay in Egypt, he founded Alexandria, which would become the prosperous capital of the Ptolemaic Kingdom after his death. Control of Egypt passed to Ptolemy I (son of Lagos), the founder of the Ptolemaic Dynasty (305-30 BC) after the death of Alexander. + +Assyria and Babylonia + +Leaving Egypt in 331 BC, Alexander marched eastward into Achaemenid Assyria in Upper Mesopotamia (now northern Iraq) and defeated Darius again at the Battle of Gaugamela. Darius once more fled the field, and Alexander chased him as far as Arbela. Gaugamela would be the final and decisive encounter between the two. Darius fled over the mountains to Ecbatana (modern Hamadan) while Alexander captured Babylon. + +Babylonian astronomical diaries say that "the king of the world, Alexander" sent his scouts with a message to the people of Babylon before entering the city: "I shall not enter your houses". + +Persia + +From Babylon, Alexander went to Susa, one of the Achaemenid capitals, and captured its treasury. He sent the bulk of his army to the Persian ceremonial capital of Persepolis via the Persian Royal Road. Alexander himself took selected troops on the direct route to the city. He then stormed the pass of the Persian Gates (in the modern Zagros Mountains) which had been blocked by a Persian army under Ariobarzanes and then hurried to Persepolis before its garrison could loot the treasury. + +On entering Persepolis, Alexander allowed his troops to loot the city for several days. Alexander stayed in Persepolis for five months. During his stay a fire broke out in the eastern palace of Xerxes I and spread to the rest of the city. Possible causes include a drunken accident or deliberate revenge for the burning of the Acropolis of Athens during the Second Persian War by Xerxes; Plutarch and Diodorus allege that Alexander's companion, the hetaera Thaïs, instigated and started the fire. Even as he watched the city burn, Alexander immediately began to regret his decision. Plutarch claims that he ordered his men to put out the fires, but that the flames had already spread to most of the city. Curtius claims that Alexander did not regret his decision until the next morning. Plutarch recounts an anecdote in which Alexander pauses and talks to a fallen statue of Xerxes as if it were a live person: + +Fall of the Persian Empire and the East + +Alexander then chased Darius, first into Media, and then Parthia. The Persian king no longer controlled his own destiny, and was taken prisoner by Bessus, his Bactrian satrap and kinsman. As Alexander approached, Bessus had his men fatally stab the Great King and then declared himself Darius's successor as Artaxerxes V, before retreating into Central Asia to launch a guerrilla campaign against Alexander. Alexander buried Darius's remains next to his Achaemenid predecessors in a regal funeral. He claimed that, while dying, Darius had named him as his successor to the Achaemenid throne. The Achaemenid Empire is normally considered to have fallen with Darius. However, as basic forms of community life and the general structure of government were maintained and resuscitated by Alexander under his own rule, he, in the words of the Iranologist Pierre Briant "may therefore be considered to have acted in many ways as the last of the Achaemenids." + +Alexander viewed Bessus as a usurper and set out to defeat him. This campaign, initially against Bessus, turned into a grand tour of central Asia. Alexander founded a series of new cities, all called Alexandria, including modern Kandahar in Afghanistan, and Alexandria Eschate ("The Furthest") in modern Tajikistan. The campaign took Alexander through Media, Parthia, Aria (West Afghanistan), Drangiana, Arachosia (South and Central Afghanistan), Bactria (North and Central Afghanistan), and Scythia. + +In 329 BC, Spitamenes, who held an undefined position in the satrapy of Sogdiana, betrayed Bessus to Ptolemy, one of Alexander's trusted companions, and Bessus was executed. However, when, at some point later, Alexander was on the Jaxartes dealing with an incursion by a horse nomad army, Spitamenes raised Sogdiana in revolt. Alexander personally defeated the Scythians at the Battle of Jaxartes and immediately launched a campaign against Spitamenes, defeating him in the Battle of Gabai. After the defeat, Spitamenes was killed by his own men, who then sued for peace. + +Problems and plots + + +During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors. This was one aspect of Alexander's broad strategy aimed at securing the aid and support of the Iranian upper classes. The Greeks however regarded the gesture of proskynesis as the province of deities and believed that Alexander meant to deify himself by requiring it. This cost him the sympathies of many of his countrymen, and he eventually abandoned it. + +During the long rule of the Achaemenids, the elite positions in many segments of the empire including the central government, the army, and the many satrapies were specifically reserved for Iranians and to a major degree Persian noblemen. The latter were in many cases additionally connected through marriage alliances with the royal Achaemenid family. This created a problem for Alexander as to whether he had to make use of the various segments and people that had given the empire its solidity and unity for a lengthy period of time. Pierre Briant explains that Alexander realized that it was insufficient to merely exploit the internal contradictions within the imperial system as in Asia Minor, Babylonia or Egypt; he also had to (re)create a central government with or without the support of the Iranians. As early as 334 BC he demonstrated awareness of this, when he challenged incumbent King Darius III "by appropriating the main elements of the Achaemenid monarchy's ideology, particularly the theme of the king who protects the lands and the peasants". Alexander wrote a letter in 332 BC to Darius III, wherein he argued that he was worthier than Darius "to succeed to the Achaemenid throne". However, Alexander's eventual decision to burn the Achaemenid palace at Persepolis in conjunction with the major rejection and opposition of the "entire Persian people" made it impracticable for him to pose himself as Darius' legitimate successor. Against Bessus (Artaxerxes V) however, Briant adds, Alexander reasserted "his claim to legitimacy as the avenger of Darius III". + +A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander. The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance. Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgmental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle. + +Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages. His official historian, Callisthenes of Olynthus, was implicated in the plot, and in the Anabasis of Alexander, Arrian states that Callisthenes and the pages were then tortured on the rack as punishment, and likely died soon after. It remains unclear if Callisthenes was actually involved in the plot, for prior to his accusation he had fallen out of favour by leading the opposition to the attempt to introduce proskynesis. + +Macedon in Alexander's absence +When Alexander set out for Asia, he left his general Antipater, an experienced military and political leader and part of Philip II's "Old Guard", in charge of Macedon. Alexander's sacking of Thebes ensured that Greece remained quiet during his absence. The one exception was a call to arms by Spartan king Agis III in 331 BC, whom Antipater defeated and killed in the battle of Megalopolis. Antipater referred the Spartans' punishment to the League of Corinth, which then deferred to Alexander, who chose to pardon them. There was also considerable friction between Antipater and Olympias, and each complained to Alexander about the other. + +In general, Greece enjoyed a period of peace and prosperity during Alexander's campaign in Asia. Alexander sent back vast sums from his conquest, which stimulated the economy and increased trade across his empire. However, Alexander's constant demands for troops and the migration of Macedonians throughout his empire depleted Macedon's strength, greatly weakening it in the years after Alexander, and ultimately led to its subjugation by Rome after the Third Macedonian War (171–168 BC). + +Coinage + +The conquest by Philip II of Pangaeum and then of the island of Thasos between 356 and 342 BC brought rich gold and silver mines under Macedonian control. + +Alexander appears to have introduced a new coinage in Cilicia in Tarsus, after the Battle of Issus in 333 BC, which went on to become the main coinage of the empire. Alexander minted gold staters, silver tetradrachms and drachims, and various fractional bronze coins. The types of these coins remained constant in his empire. The gold series had the head of Athena on the obverse and a winged Nike (Victory) on the reverse. The silver coinage had a beardless head of Heracles wearing a lionskin headdress on the obverse and Zeus aetophoros ('eagle bearer') enthroned with a scepter in his left hand, on the reverse. There are both Greek and non-Greek aspects to this design. Heracles and Zeus were important deities for the Macedonians, with Heracles considered to be the ancestor of the Temenid dynasty and Zeus the patron of the main Macedonian sanctuary, Dium. However, the lion was also the symbolic animal of the Anatolian god Sandas, worshipped at Tarsus. The reverse design of Alexander's tetradrachms is closely modelled on the depiction of the god Baaltars (Baal of Tarsus), on the silver staters minted at Tarsus by the Persian satrap Mazaeus before Alexander's conquest. + +Alexander did not attempt to impose uniform imperial coinage throughout his new conquests. Persian coins continued to circulate in all the satrapies of the empire. + +Indian campaign + +Forays into the Indian subcontinent + + +After the death of Spitamenes and his marriage to Roxana (Raoxshna in Old Iranian) to cement relations with his new satrapies, Alexander turned to the Indian subcontinent. He invited the chieftains of the former satrapy of Gandhara (a region presently straddling eastern Afghanistan and northern Pakistan), to come to him and submit to his authority. Omphis (Indian name Ambhi), the ruler of Taxila, whose kingdom extended from the Indus to the Hydaspes (Jhelum), complied, but the chieftains of some hill clans, including the Aspasioi and Assakenoi sections of the Kambojas (known in Indian texts also as Ashvayanas and Ashvakayanas), refused to submit. Ambhi hastened to relieve Alexander of his apprehension and met him with valuable presents, placing himself and all his forces at his disposal. Alexander not only returned Ambhi his title and the gifts but he also presented him with a wardrobe of "Persian robes, gold and silver ornaments, 30 horses and 1,000 talents in gold". Alexander was emboldened to divide his forces, and Ambhi assisted Hephaestion and Perdiccas in constructing a bridge over the Indus where it bends at Hund, supplied their troops with provisions, and received Alexander himself, and his whole army, in his capital city of Taxila, with every demonstration of friendship and the most liberal hospitality. + +On the subsequent advance of the Macedonian king, Taxiles accompanied him with a force of 5,000 men and took part in the Battle of the Hydaspes. After that victory, he was sent by Alexander in pursuit of Porus, to whom he was charged to offer favourable terms, but narrowly escaped losing his life at the hands of his old enemy. Subsequently, however, the two rivals were reconciled by the personal mediation of Alexander; and Taxiles, after having contributed zealously to the equipment of the fleet on the Hydaspes, was entrusted by the king with the government of the whole territory between that river and the Indus. A considerable accession of power was granted him after the death of Philip, son of Machatas; and he was allowed to retain his authority at the death of Alexander himself (323 BC), as well as in the subsequent partition of the provinces at Triparadisus, 321 BC. + +In the winter of 327/326 BC, Alexander personally led a campaign against the Aspasioi of the Kunar Valley, the Guraeans of the Guraeus Valley, and the Assakenoi of the Swat and Buner Valleys. A fierce contest ensued with the Aspasioi in which Alexander was wounded in the shoulder by a dart, but eventually the Aspasioi lost. Alexander then faced the Assakenoi, who fought against him from the strongholds of Massaga, Ora and Aornos. + +The fort of Massaga was reduced only after days of bloody fighting, in which Alexander was wounded seriously in the ankle. According to Curtius, "Not only did Alexander slaughter the entire population of Massaga, but also did he reduce its buildings to rubble." A similar slaughter followed at Ora. In the aftermath of Massaga and Ora, numerous Assakenians fled to the fortress of Aornos. Alexander followed close behind and captured the strategic hill-fort after four bloody days. + +After Aornos, Alexander crossed the Indus and fought and won an epic battle against King Porus, who ruled a region lying between the Hydaspes and the Acesines (Chenab), in what is now the Punjab, in the Battle of the Hydaspes in 326 BC. Alexander was impressed by Porus's bravery, and made him an ally. He appointed Porus as satrap, and added to Porus's territory land that he did not previously own, towards the south-east, up to the Hyphasis (Beas). Choosing a local helped him control these lands so distant from Greece. Alexander founded two cities on opposite sides of the Hydaspes river, naming one Bucephala, in honour of his horse, who died around this time. The other was Nicaea (Victory), thought to be located at the site of modern-day Mong, Punjab. Philostratus the Elder in the Life of Apollonius of Tyana writes that in the army of Porus there was an elephant who fought brave against Alexander's army and Alexander dedicated it to the Helios (Sun) and named it Ajax, because he thought that a so great animal deserved a great name. The elephant had gold rings around its tusks and an inscription was on them written in Greek: "Alexander the son of Zeus dedicates Ajax to the Helios" (ΑΛΕΞΑΝΔΡΟΣ Ο ΔΙΟΣ ΤΟΝ ΑΙΑΝΤΑ ΤΩΙ ΗΛΙΩΙ). + +Revolt of the Hellenic army + +East of Porus's kingdom, near the Ganges River, was the Nanda Empire of Magadha, and further east, the Gangaridai Empire of Bengal region of the Indian subcontinent. Fearing the prospect of facing other large armies and exhausted by years of campaigning, Alexander's army mutinied at the Hyphasis River (Beas), refusing to march farther east. This river thus marks the easternmost extent of Alexander's conquests. + +Alexander tried to persuade his soldiers to march farther, but his general Coenus pleaded with him to change his opinion and return; the men, he said, "longed to again see their parents, their wives and children, their homeland". Alexander eventually agreed and turned south, marching along the Indus. Along the way his army conquered the Malhi (in modern-day Multan) and other Indian tribes; while besieging the Mallian citadel, Alexander suffered a near-fatal injury when an arrow penetrated his armor and entered his lung. + +Alexander sent much of his army to Carmania (modern southern Iran) with general Craterus, and commissioned a fleet to explore the Persian Gulf shore under his admiral Nearchus, while he led the rest back to Persia through the more difficult southern route along the Gedrosian Desert and Makran. Alexander reached Susa in 324 BC, but not before losing many men to the harsh desert. + +Last years in Persia + +Discovering that many of his satraps and military governors had misbehaved in his absence, Alexander executed several of them as examples on his way to Susa. As a gesture of thanks, he paid off the debts of his soldiers, and announced that he would send over-aged and disabled veterans back to Macedon, led by Craterus. His troops misunderstood his intention and mutinied at the town of Opis. They refused to be sent away and criticized his adoption of Persian customs and dress and the introduction of Persian officers and soldiers into Macedonian units. + +After three days, unable to persuade his men to back down, Alexander gave Persians command posts in the army and conferred Macedonian military titles upon Persian units. The Macedonians quickly begged forgiveness, which Alexander accepted, and held a great banquet with several thousand of his men. In an attempt to craft a lasting harmony between his Macedonian and Persian subjects, Alexander held a mass marriage of his senior officers to Persian and other noblewomen at Susa, but few of those marriages seem to have lasted much beyond a year. + +Meanwhile, upon his return to Persia, Alexander learned that guards of the tomb of Cyrus the Great in Pasargadae had desecrated it, and swiftly executed them. Alexander admired Cyrus the Great, from an early age reading Xenophon's Cyropaedia, which described Cyrus's heroism in battle and governance as a king and legislator. During his visit to Pasargadae, Alexander ordered his architect Aristobulus to decorate the interior of the sepulchral chamber of Cyrus's tomb. + +Afterwards, Alexander travelled to Ecbatana to retrieve the bulk of the Persian treasure. There, his closest friend, Hephaestion, died of illness or poisoning. Hephaestion's death devastated Alexander and he ordered the preparation of an expensive funeral pyre in Babylon along with a decree for public mourning. Back in Babylon, Alexander planned a series of new campaigns, beginning with an invasion of Arabia, but he would not have a chance to realize them, as he died shortly after Hephaestion. + +On the evening of May 29, Alexander organized a banquet for his army to celebrate the end of the campaign of India and the onset of the invasion of the Arabian Peninsula. There is a tradition that they would only start serious drinking after everyone was done with their meals, but the wine was usually heavily watered. + +Death and succession + +Before his death, someone asked Alexander on who would be his designated successor should he die, he responded: "To the strongest one." He may have also added that there would be funeral games to be played after his death. + +On either 10 or 11 June 323 BC, Alexander died in the palace of Nebuchadnezzar II, in Babylon, at age 32. There are two different versions of Alexander's death, differing slightly in details. Plutarch's account is that roughly 14 days before his death, Alexander entertained admiral Nearchus and spent the night and next day drinking with Medius of Larissa. Alexander developed a fever, which worsened until he was unable to speak. The common soldiers, anxious about his health, were granted the right to file past him as he silently waved at them. In the second account, Diodorus recounts that Alexander was struck with pain after downing a large bowl of unmixed wine in honour of Heracles followed by 11 days of weakness; he did not develop a fever, instead dying after some agony. Arrian also mentioned this as an alternative, but Plutarch specifically denied this claim. + +Given the propensity of the Macedonian aristocracy to assassination, foul play featured in multiple accounts of his death. Diodorus, Plutarch, Arrian and Justin all mentioned the theory that Alexander was poisoned. Justin stated that Alexander was the victim of a poisoning conspiracy, Plutarch dismissed it as a fabrication, while both Diodorus and Arrian noted that they mentioned it only for the sake of completeness. The accounts were nevertheless fairly consistent in designating Antipater, recently removed as Macedonian viceroy, replaced by Craterus, as the head of the alleged plot. Perhaps taking his summons to Babylon as a death sentence and having seen the fate of Parmenion and Philotas, Antipater purportedly arranged for Alexander to be poisoned by his son Iollas, who was Alexander's wine-pourer. There was even a suggestion that Aristotle may have participated. +The strongest argument against the poison theory is the fact that twelve days passed between the start of his illness and his death; such long-acting poisons were probably not available. However, in a 2003 BBC documentary investigating the death of Alexander, Leo Schep from the New Zealand National Poisons Centre proposed that the plant white hellebore (Veratrum album), which was known in antiquity, may have been used to poison Alexander. In a 2014 manuscript in the journal Clinical Toxicology, Schep suggested Alexander's wine was spiked with Veratrum album, and that this would produce poisoning symptoms that match the course of events described in the Alexander Romance. Veratrum album poisoning can have a prolonged course and it was suggested that if Alexander was poisoned, Veratrum album offers the most plausible cause. Another poisoning explanation put forward in 2010 proposed that the circumstances of his death were compatible with poisoning by water of the river Styx (modern-day Mavroneri in Arcadia, Greece) that contained calicheamicin, a dangerous compound produced by bacteria. + +Several natural causes (diseases) have been suggested, including malaria and typhoid fever. A 1998 article in the New England Journal of Medicine attributed his death to typhoid fever complicated by bowel perforation and ascending paralysis. Another recent analysis suggested pyogenic (infectious) spondylitis or meningitis. Other illnesses fit the symptoms, including acute pancreatitis, West Nile virus, and Guillain-Barré syndrome. Natural-cause theories also tend to emphasize that Alexander's health may have been in general decline after years of heavy drinking and severe wounds. The anguish that Alexander felt after Hephaestion's death may also have contributed to his declining health. + +Post-death events + +Alexander's body was laid in a gold anthropoid sarcophagus that was filled with honey, which was in turn placed in a gold casket. According to Aelian, a seer called Aristander foretold that the land where Alexander was laid to rest "would be happy and unvanquishable forever". Perhaps more likely, the successors may have seen possession of the body as a symbol of legitimacy, since burying the prior king was a royal prerogative. + +While Alexander's funeral cortege was on its way to Macedon, Ptolemy seized it and took it temporarily to Memphis. His successor, Ptolemy II Philadelphus, transferred the sarcophagus to Alexandria, where it remained until at least late Antiquity. Ptolemy IX Lathyros, one of Ptolemy's final successors, replaced Alexander's sarcophagus with a glass one so he could convert the original to coinage. The recent discovery of an enormous tomb in northern Greece, at Amphipolis, dating from the time of Alexander the Great has given rise to speculation that its original intent was to be the burial place of Alexander. This would fit with the intended destination of Alexander's funeral cortege. However, the memorial was found to be dedicated to the dearest friend of Alexander the Great, Hephaestion. + +Pompey, Julius Caesar and Augustus all visited the tomb in Alexandria, where Augustus, allegedly, accidentally knocked the nose off. Caligula was said to have taken Alexander's breastplate from the tomb for his own use. Around AD 200, Emperor Septimius Severus closed Alexander's tomb to the public. His son and successor, Caracalla, a great admirer, visited the tomb during his own reign. After this, details on the fate of the tomb are hazy. + +The so-called "Alexander Sarcophagus", discovered near Sidon and now in the Istanbul Archaeology Museum, is so named not because it was thought to have contained Alexander's remains, but because its bas-reliefs depict Alexander and his companions fighting the Persians and hunting. It was originally thought to have been the sarcophagus of Abdalonymus (died 311 BC), the king of Sidon appointed by Alexander immediately following the battle of Issus in 331. However, more recently, it has been suggested that it may date from earlier than Abdalonymus's death. + +Demades likened the Macedonian army, after the death of Alexander, to the blinded Cyclops, due to the many random and disorderly movements that it made. In addition, Leosthenes, also, likened the anarchy between the generals, after Alexander's death, to the blinded Cyclops "who after he had lost his eye went feeling and groping about with his hands before him, not knowing where to lay them". + +Division of the Macedonian Empire + +Alexander's death was so sudden that when reports of his death reached Greece, they were not immediately believed. Alexander had no obvious or legitimate heir, his son Alexander IV by Roxane being born after Alexander's death. According to Diodorus, Alexander's companions asked him on his deathbed to whom he bequeathed his kingdom; his laconic reply was "tôi kratistôi"—"to the strongest". Another theory is that his successors wilfully or erroneously misheard "tôi Kraterôi"—"to Craterus", the general leading his Macedonian troops home and newly entrusted with the regency of Macedonia. + +Arrian and Plutarch claimed that Alexander was speechless by this point, implying that this was an apocryphal story. Diodorus, Curtius and Justin offered the more plausible story that Alexander passed his signet ring to Perdiccas, a bodyguard and leader of the companion cavalry, in front of witnesses, thereby nominating him. + +Perdiccas initially did not claim power, instead suggesting that Roxane's baby would be king, if male, with himself, Craterus, Leonnatus, and Antipater as guardians. However, the infantry, under the command of Meleager, rejected this arrangement since they had been excluded from the discussion. Instead, they supported Alexander's half-brother Philip Arrhidaeus. Eventually, the two sides reconciled, and after the birth of Alexander IV, he and Philip III were appointed joint kings, albeit in name only. + +Dissension and rivalry soon affected the Macedonians, however. The satrapies handed out by Perdiccas at the Partition of Babylon became power bases each general used to bid for power. After the assassination of Perdiccas in 321 BC, Macedonian unity collapsed, and 40 years of war between "The Successors" (Diadochi) ensued before the Hellenistic world settled into three stable power blocs: Ptolemaic Egypt, Seleucid Syria and East, and Antigonid Macedonia. In the process, both Alexander IV and Philip III were murdered. + +Last plans + +Diodorus stated that Alexander had given detailed written instructions to Craterus some time before his death, which are known as Alexander's "last plans". Craterus started to carry out Alexander's commands, but the successors chose not to further implement them, on the grounds they were impractical and extravagant. Furthermore, Perdiccas had read the notebooks containing Alexander's last plans to the Macedonian troops in Babylon, who voted not to carry them out. + +According to Diodorus, Alexander's last plans called for military expansion into the southern and western Mediterranean, monumental constructions, and the intermixing of Eastern and Western populations. It included: + Construction of 1,000 ships larger than triremes, along with harbours and a road running along the African coast all the way to the Pillars of Hercules, to be used for an invasion of Carthage and the western Mediterranean; + Erection of great temples in Delos, Delphi, Dodona, Dium, Amphipolis, all costing 1,500 talents, and a monumental temple to Athena at Troy + Amalgamation of small settlements into larger cities ("synoecisms") and the "transplant of populations from Asia to Europe and in the opposite direction from Europe to Asia, in order to bring the largest continent to common unity and to friendship by means of intermarriage and family ties" + Construction of a monumental tomb for his father Philip, "to match the greatest of the pyramids of Egypt" + Conquest of Arabia + Circumnavigation of Africa + +The enormous scale of these plans has led many scholars to doubt their historicity. Ernst Badian argued that they were exaggerated by Perdiccas in order to ensure that the Macedonian troops voted not to carry them out. Other scholars have proposed that they were invented by later authors within the tradition of the Alexander Romance. + +Character + +Generalship + +Alexander perhaps earned the epithet "the Great" due to his unparalleled success as a military commander; he never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. The Macedonian phalanx, armed with the sarissa, a spear long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and manoeuvrability to great effect against larger but more disparate Persian forces. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king. + +In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000. Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about . By contrast, the Persian infantry was stationed behind its cavalry. This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persians' scimitars and javelins. Macedonian losses were negligible compared to those of the Persians. + +At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius's center, causing the latter to flee once again. + +When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center. In India, confronted by Porus's elephant corps, the Macedonians opened their ranks to envelop the elephants and used their sarissas to strike upwards and dislodge the elephants' handlers. + +Physical appearance + +Historical sources frequently give conflicting accounts of Alexander's appearance, and the earliest sources are the most scant in their detail. During his lifetime, Alexander carefully curated his image by commissioning works from famous and great artists of the time. This included commissioning sculptures by Lysippos, paintings by Apelles and gem engravings by Pyrgoteles. Ancient authors recorded that Alexander was so pleased with portraits of himself created by Lysippos that he forbade other sculptors from crafting his image; scholars today, however, find the claim dubious. Nevertheless, Andrew Stewart highlights the fact that artistic portraits, not least because of who they are commissioned by, are always partisan, and that artistic portrayals of Alexander "seek to legitimize him (or, by extension, his Successors), to interpret him to their audiences, to answer their critiques, and to persuade them of his greatness", and thus should be considered within a framework of "praise and blame", in the same way sources such as praise poetry are. Despite those caveats, Lysippos's sculpture, famous for its naturalism, as opposed to a stiffer, more static pose, is thought to be the most faithful depiction. + +Curtius Rufus, a Roman historian from the first century AD, who wrote the Histories of Alexander the Great, gives this account of Alexander sitting on the throne of Darius III: + +Both Curtius and Diodorus report a story that when Darius III's mother, Sisygambis, first met Alexander and Hephaestion, she assumed that the latter was Alexander because he was the taller and more handsome of the two. + +The Greek biographer Plutarch () discusses the accuracy of his depictions: + +Historians have understood the detail of the pleasant odour attributed to Alexander as stemming from a belief in ancient Greece that pleasant scents are characteristic of gods and heroes. + +The Alexander Mosaic and contemporary coins portray Alexander with "a straight nose, a slightly protruding jaw, full lips and eyes deep set beneath a strongly pronounced forehead". He is also described as having a slight upward tilt of his head to the left. + +The ancient historian Aelian ( – ), in his Varia Historia (12.14), describes Alexander's hair color as "ξανθὴν", that could mean yellowish, reddish or brownish. It is sometimes claimed that Alexander had one blue and one brown eye. Reconstruction, based on remaining traces of paint, of the original polychromy on his sarcophagus indicates that he was depicted with brown eyes and chestnut brown hair. + +Personality + +Both of Alexander's parents encouraged his ambitions. His father Philip was probably Alexander's most immediate and influential role model, as the young Alexander watched him campaign practically every year, winning victory after victory while ignoring severe wounds. Alexander's relationship with his father "forged" the competitive side of his personality; he had a need to outdo his father, illustrated by his reckless behavior in battle. While Alexander worried that his father would leave him "no great or brilliant achievement to be displayed to the world", he also downplayed his father's achievements to his companions. Alexander's mother Olympia similarly had huge ambitions, and encouraged her son to believe it was his destiny to conquer the Persian Empire. She instilled a sense of destiny in him, and Plutarch tells how his ambition "kept his spirit serious and lofty in advance of his years". + +According to Plutarch, Alexander also had a violent temper and rash, impulsive nature, and this could influence his decision making. Although Alexander was stubborn and did not respond well to orders from his father, he was open to reasoned debate. He had a calmer side—perceptive, logical, and calculating. He had a great desire for knowledge, a love for philosophy, and was an avid reader. This was no doubt in part due to Aristotle's tutelage; Alexander was intelligent and quick to learn. His intelligent and rational side was amply demonstrated by his ability and success as a general. He had great self-restraint in "pleasures of the body", in contrast with his lack of self-control with alcohol. + +Alexander was erudite and patronized both arts and sciences. However, he had little interest in sports or the Olympic Games (unlike his father), seeking only the Homeric ideals of honour (timê) and glory (kudos). He had great charisma and force of personality, characteristics which made him a great leader. His unique abilities were further demonstrated by the inability of any of his generals to unite Macedonia and retain the Empire after his death—only Alexander had the ability to do so. + +During his final years, and especially after the death of Hephaestion, Alexander began to exhibit signs of megalomania and paranoia. His extraordinary achievements, coupled with his own ineffable sense of destiny and the flattery of his companions, may have combined to produce this effect. His delusions of grandeur are readily visible in his will and in his desire to conquer the world, in as much as he is by various sources described as having boundless ambition, an epithet, the meaning of which has descended into a historical cliché. + +He appears to have believed himself a deity, or at least sought to deify himself. Olympias always insisted to him that he was the son of Zeus, a theory apparently confirmed to him by the oracle of Amun at Siwa. He began to identify himself as the son of Zeus-Ammon. Alexander adopted elements of Persian dress and customs at court, notably proskynesis, which was one aspect of Alexander's broad strategy aimed at securing the aid and support of the Iranian upper classes; however the practise of proskynesis was disapproved by the Macedonians, and they were unwilling to perform it. This behaviour cost him the sympathies of many of his countrymen. However, Alexander also was a pragmatic ruler who understood the difficulties of ruling culturally disparate peoples, many of whom lived in kingdoms where the king was divine. Thus, rather than megalomania, his behaviour may have been a practical attempt at strengthening his rule and keeping his empire together. + +Personal relationships + +Alexander married three times: Roxana, daughter of the Sogdian nobleman Oxyartes of Bactria, out of love; and the Persian princesses Stateira and Parysatis, the former a daughter of Darius III and the latter a daughter of Artaxerxes III, for political reasons. He apparently had two sons, Alexander IV of Macedon by Roxana and, possibly, Heracles of Macedon from his mistress Barsine. He lost another child when Roxana miscarried at Babylon. + +Alexander also had a close relationship with his friend, general, and bodyguard Hephaestion, the son of a Macedonian noble. Hephaestion's death devastated Alexander. This event may have contributed to Alexander's failing health and detached mental state during his final months. + +Alexander's sexuality has been the subject of speculation and controversy in modern times. The Roman era writer Athenaeus says, based on the scholar Dicaearchus, who was Alexander's contemporary, that the king "was quite excessively keen on boys", and that Alexander kissed the eunuch Bagoas in public. This episode is also told by Plutarch, probably based on the same source. None of Alexander's contemporaries, however, are known to have explicitly described Alexander's relationship with Hephaestion as sexual, though the pair was often compared to Achilles and Patroclus, whom classical Greek culture painted as a couple. Aelian writes of Alexander's visit to Troy where "Alexander garlanded the tomb of Achilles, and Hephaestion that of Patroclus, the latter hinting that he was a beloved of Alexander, in just the same way as Patroclus was of Achilles." Some modern historians (e.g., Robin Lane Fox) believe not only that Alexander's youthful relationship with Hephaestion was sexual, but that their sexual contacts may have continued into adulthood, which went against the social norms of at least some Greek cities, such as Athens, though some modern researchers have tentatively proposed that Macedonia (or at least the Macedonian court) may have been more tolerant of homosexuality between adults. + +Green argues that there is little evidence in ancient sources that Alexander had much carnal interest in women; he did not produce an heir until the very end of his life. However, Ogden calculates that Alexander, who impregnated his partners thrice in eight years, had a higher matrimonial record than his father at the same age. Two of these pregnancies — Stateira's and Barsine's — are of dubious legitimacy. + +According to Diodorus Siculus, Alexander accumulated a harem in the style of Persian kings, but he used it rather sparingly, "not wishing to offend the Macedonians", showing great self-control in "pleasures of the body". Nevertheless, Plutarch described how Alexander was infatuated by Roxana while complimenting him on not forcing himself on her. Green suggested that, in the context of the period, Alexander formed quite strong friendships with women, including Ada of Caria, who adopted him, and even Darius's mother Sisygambis, who supposedly died from grief upon hearing of Alexander's death. + +Battle record + +Legacy + +Alexander's legacy extended beyond his military conquests, and his reign marked a turning point in European and Asian history. His campaigns greatly increased contacts and trade between East and West, and vast areas to the east were significantly exposed to Greek civilization and influence. Some of the cities he founded became major cultural centers, many surviving into the 21st century. His chroniclers recorded valuable information about the areas through which he marched, while the Greeks themselves got a sense of belonging to a world beyond the Mediterranean. + +Hellenistic kingdoms + +Alexander's most immediate legacy was the introduction of Macedonian rule to huge new swathes of Asia. At the time of his death, Alexander's empire covered some , and was the largest state of its time. Many of these areas remained in Macedonian hands or under Greek influence for the next 200–300 years. The successor states that emerged were, at least initially, dominant forces, and these 300 years are often referred to as the Hellenistic period. + +The eastern borders of Alexander's empire began to collapse even during his lifetime. However, the power vacuum he left in the northwest of the Indian subcontinent directly gave rise to one of the most powerful Indian dynasties in history, the Maurya Empire. Taking advantage of this power vacuum, Chandragupta Maurya (referred to in Greek sources as "Sandrokottos"), of relatively humble origin, took control of the Punjab, and with that power base proceeded to conquer the Nanda Empire. + +Founding of cities + +Over the course of his conquests, Alexander founded some twenty cities that bore his name, most of them east of the Tigris. The first, and greatest, was Alexandria in Egypt, which would become one of the leading Mediterranean cities. The cities' locations reflected trade routes as well as defensive positions. At first, the cities must have been inhospitable, little more than defensive garrisons. Following Alexander's death, many Greeks who had settled there tried to return to Greece. However, a century or so after Alexander's death, many of the Alexandrias were thriving, with elaborate public buildings and substantial populations that included both Greek and local peoples. + +The foundation of the "new" Smyrna was also associated with Alexander. According to the legend, after Alexander hunted on the Mount Pagus, he slept under a plane tree at the sanctuary of Nemesis. While he was sleeping, the goddess appeared and told him to found a city there and move into it the Smyrnaeans from the "old" city. The Smyrnaeans sent ambassadors to the oracle at Clarus to ask about this, and after the response from the oracle they decided to move to the "new" city. + +The city of Pella, in modern Jordan, was founded by veterans of Alexander's army, and named it after the city of Pella, in Greece, which was the birthplace of Alexander. + +Modern cities still named after Alexander the Great include: Alexandria (Egypt), Alexandreia (Greece), Iskenderun (Turkey), Iskandariya (Iraq) and Kandahar (Afghanistan). + +Funding of temples + +In 334 BC, Alexander the Great donated funds for the completion of the new temple of Athena Polias in Priene, in modern-day western Turkey. An inscription from the temple, now housed in the British Museum, declares: "King Alexander dedicated [this temple] to Athena Polias." This inscription is one of the few independent archaeological discoveries confirming an episode from Alexander's life. The temple was designed by Pytheos, one of the architects of the Mausoleum at Halicarnassus. + +Libanius wrote that Alexander founded the temple of Zeus Bottiaios (), in the place where later the city of Antioch was built. + +Suda wrote that Alexander built a big temple to Sarapis. + +Hellenization + +Hellenization was coined by the German historian Johann Gustav Droysen to denote the spread of Greek language, culture, and population into the former Persian empire after Alexander's conquest. This process can be seen in such great Hellenistic cities as Alexandria, Antioch and Seleucia (south of modern Baghdad). Alexander sought to insert Greek elements into Persian culture and to hybridize Greek and Persian culture, homogenizing the populations of Asia and Europe. Although his successors explicitly rejected such policies, Hellenization occurred throughout the region, accompanied by a distinct and opposite 'Orientalization' of the successor states. + +The core of the Hellenistic culture promulgated by the conquests was essentially Athenian. The close association of men from across Greece in Alexander's army directly led to the emergence of the largely Attic-based "koine", or "common" Greek dialect. Koine spread throughout the Hellenistic world, becoming the lingua franca of Hellenistic lands and eventually the ancestor of modern Greek. Furthermore, town planning, education, local government, and art current in the Hellenistic period were all based on Classical Greek ideals, evolving into distinct new forms commonly grouped as Hellenistic. Also, the New Testament was written in the Koine Greek language. Aspects of Hellenistic culture were still evident in the traditions of the Byzantine Empire in the mid-15th century. + +Hellenization in South and Central Asia + +Some of the most pronounced effects of Hellenization can be seen in Afghanistan and India, in the region of the relatively late-rising Greco-Bactrian Kingdom (250–125 BC) (in modern Afghanistan, Pakistan, and Tajikistan) and the Indo-Greek Kingdom (180 BC – 10 AD) in modern Afghanistan and India. On the Silk Road trade routes, Hellenistic culture hybridized with Iranian and Buddhist cultures. The cosmopolitan art and mythology of Gandhara (a region spanning the upper confluence of the Indus, Swat and Kabul rivers in modern Pakistan) of the ~3rd century BC to the ~5th century AD are most evident of the direct contact between Hellenistic civilization and South Asia, as are the Edicts of Ashoka, which directly mention the Greeks within Ashoka's dominion as converting to Buddhism and the reception of Buddhist emissaries by Ashoka's contemporaries in the Hellenistic world. The resulting syncretism known as Greco-Buddhism influenced the development of Buddhism and created a culture of Greco-Buddhist art. These Greco-Buddhist kingdoms sent some of the first Buddhist missionaries to China, Sri Lanka and Hellenistic Asia and Europe (Greco-Buddhist monasticism). + +Some of the first and most influential figurative portrayals of the Buddha appeared at this time, perhaps modelled on Greek statues of Apollo in the Greco-Buddhist style. Several Buddhist traditions may have been influenced by the ancient Greek religion: the concept of Boddhisatvas is reminiscent of Greek divine heroes, and some Mahayana ceremonial practices (burning incense, gifts of flowers, and food placed on altars) are similar to those practised by the ancient Greeks; however, similar practices were also observed amongst the native Indic culture. One Greek king, Menander I, probably became Buddhist, and was immortalized in Buddhist literature as 'Milinda'. The process of Hellenization also spurred trade between the east and west. For example, Greek astronomical instruments dating to the 3rd century BC were found in the Greco-Bactrian city of Ai Khanoum in modern-day Afghanistan, while the Greek concept of a spherical Earth surrounded by the spheres of planets eventually supplanted the long-standing Indian cosmological belief of a disc consisting of four continents grouped around a central mountain (Mount Meru) like the petals of a flower. The Yavanajataka (lit. Greek astronomical treatise) and Paulisa Siddhanta texts depict the influence of Greek astronomical ideas on Indian astronomy. + +Following the conquests of Alexander the Great in the east, Hellenistic influence on Indian art was far-ranging. In the area of architecture, a few examples of the Ionic order can be found as far as Pakistan with the Jandial temple near Taxila. Several examples of capitals displaying Ionic influences can be seen as far as Patna, especially with the Pataliputra capital, dated to the 3rd century BC. The Corinthian order is also heavily represented in the art of Gandhara, especially through Indo-Corinthian capitals. + +Influence on Rome + +Alexander and his exploits were admired by many Romans, especially generals, who wanted to associate themselves with his achievements. Polybius began his Histories by reminding Romans of Alexander's achievements, and thereafter Roman leaders saw him as a role model. Pompey the Great adopted the epithet "Magnus" and even Alexander's anastole-type haircut, and searched the conquered lands of the east for Alexander's 260-year-old cloak, which he then wore as a sign of greatness. Julius Caesar dedicated a Lysippean equestrian bronze statue but replaced Alexander's head with his own, while Octavian visited Alexander's tomb in Alexandria and temporarily changed his seal from a sphinx to Alexander's profile. The emperor Trajan also admired Alexander, as did Nero and Caracalla. The Macriani, a Roman family that in the person of Macrinus briefly ascended to the imperial throne, kept images of Alexander on their persons, either on jewellery, or embroidered into their clothes. + +On the other hand, some Roman writers, particularly Republican figures, used Alexander as a cautionary tale of how autocratic tendencies can be kept in check by republican values. Alexander was used by these writers as an example of ruler values such as (friendship) and (clemency), but also (anger) and (over-desire for glory). + +Emperor Julian in his satire called "The Caesars", describes a contest between the previous Roman emperors, with Alexander the Great called in as an extra contestant, in the presence of the assembled gods. + +The Itinerarium Alexandri is a 4th-century Latin Itinerarium which describes Alexander the Great's campaigns. Julius Caesar went to serve his quaestorship in Hispania after his wife's funeral, in the spring or early summer of 69 BC. While there, he encountered a statue of Alexander the Great, and realised with dissatisfaction that he was now at an age when Alexander had the world at his feet, while he had achieved comparatively little. + +Pompey posed as the "new Alexander" since he was his boyhood hero. + +After Caracalla concluded his campaign against the Alamanni, it became evident that he was inordinately preoccupied with Alexander the Great. He began openly mimicking Alexander in his personal style. In planning his invasion of the Parthian Empire, Caracalla decided to arrange 16,000 of his men in Macedonian-style phalanxes, despite the Roman army having made the phalanx an obsolete tactical formation. The historian Christopher Matthew mentions that the term Phalangarii has two possible meanings, both with military connotations. The first refers merely to the Roman battle line and does not specifically mean that the men were armed with pikes, and the second bears similarity to the 'Marian Mules' of the late Roman Republic who carried their equipment suspended from a long pole, which were in use until at least the 2nd century AD. As a consequence, the Phalangarii of Legio II Parthica may not have been pikemen, but rather standard battle line troops or possibly Triarii. + +Caracalla's mania for Alexander went so far that Caracalla visited Alexandria while preparing for his Persian invasion and persecuted philosophers of the Aristotelian school based on a legend that Aristotle had poisoned Alexander. This was a sign of Caracalla's increasingly erratic behaviour. But this mania for Alexander, strange as it was, was overshadowed by subsequent events in Alexandria. + +In 39, Caligula performed a spectacular stunt by ordering a temporary floating bridge to be built using ships as pontoons, stretching for over two miles from the resort of Baiae to the neighbouring port of Puteoli. It was said that the bridge was to rival the Persian king Xerxes' pontoon bridge crossing of the Hellespont. Caligula, who could not swim, then proceeded to ride his favourite horse Incitatus across, wearing the breastplate of Alexander the Great. This act was in defiance of a prediction by Tiberius's soothsayer Thrasyllus of Mendes that Caligula had "no more chance of becoming emperor than of riding a horse across the Bay of Baiae". + +The diffusion of Greek culture and language cemented by Alexander's conquests in West Asia and North Africa served as a "precondition" for the later Roman expansion into these territories and entire basis for the Byzantine Empire, according to Errington. + +Letters + +Alexander wrote and received numerous letters, but no originals survive. A few official letters addressed to the Greek cities survive in copies inscribed in stone and the content of others is sometimes reported in historical sources. These only occasionally quote the letters and it is an open question how reliable such quotations are. Several fictitious letters, some perhaps based on actual letters, made their way into the Romance tradition. + +In legend + +Many of the legends about Alexander derive from his own lifetime, probably encouraged by Alexander himself. His court historian Callisthenes portrayed the sea in Cilicia as drawing back from him in proskynesis. Writing shortly after Alexander's death, Onesicritus invented a tryst between Alexander and Thalestris, queen of the mythical Amazons. He reportedly read this passage to his patron King Lysimachus, who had been one of Alexander's generals and who quipped, "I wonder where I was at the time." + +In the first centuries after Alexander's death, probably in Alexandria, a quantity of the legendary material coalesced into a text known as the Alexander Romance, later falsely ascribed to Callisthenes and therefore known as Pseudo-Callisthenes. This text underwent numerous expansions and revisions throughout Antiquity and the Middle Ages, containing many dubious stories, and was translated into numerous languages, for example Middle Persian, Syriac and probably Arabic. + +In ancient and modern culture + +Alexander the Great's accomplishments and legacy have been depicted in many cultures. Alexander has figured in both high and popular culture beginning in his own era to the present day. The Alexander Romance, in particular, has had a significant impact on portrayals of Alexander in later cultures, from Persian to medieval European to modern Greek. + +Alexander features prominently in modern Greek folklore, more so than any other ancient figure. The colloquial form of his name in modern Greek ("O Megalexandros") is a household name, and he is the only ancient hero to appear in the Karagiozis shadow play. One well-known fable among Greek seamen involves a solitary mermaid who would grasp a ship's prow during a storm and ask the captain "Is King Alexander alive?" The correct answer is "He is alive and well and rules the world!" causing the mermaid to vanish and the sea to calm. Any other answer would cause the mermaid to turn into a raging Gorgon who would drag the ship to the bottom of the sea, all hands aboard. + +In pre-Islamic Middle Persian (Zoroastrian) literature, Alexander is referred to by the epithet gujastak, meaning "accursed", and is accused of destroying temples and burning the sacred texts of Zoroastrianism. In Islamic Persia, under the influence of the Alexander Romance (in Iskandarnamah), a more positive portrayal of Alexander emerges. Firdausi's Shahnameh ("The Book of Kings") includes Alexander in a line of legitimate Persian shahs, a mythical figure who explored the far reaches of the world in search of the Fountain of Youth. In the Shahnameh, Alexander's first journey is to Mecca to pray at the Kaaba. Alexander was depicted as performing a Hajj (pilgrimage to Mecca) many times in subsequent Islamic art and literature. Later Persian writers associate him with philosophy, portraying him at a symposium with figures such as Socrates, Plato and Aristotle, in search of immortality. + +The figure of Dhu al-Qarnayn (literally "the Two-Horned One") mentioned in the Quran is believed by scholars to be based on later legends of Alexander. In this tradition, he was a heroic figure who built a wall to defend against the nations of Gog and Magog. He then travelled the known world in search of the Water of Life and Immortality, eventually becoming a prophet. The majority of modern researchers of the Quran as well as Islamic commentators identify Dhu al-Qarnayn as Alexander the Great. + +The Syriac version of the Alexander Romance portrays him as an ideal Christian world conqueror who prayed to "the one true God". In Egypt, Alexander was portrayed as the son of Nectanebo II, the last pharaoh before the Persian conquest. His defeat of Darius was depicted as Egypt's salvation, "proving" Egypt was still ruled by an Egyptian. + +According to Josephus, Alexander was shown the Book of Daniel when he entered Jerusalem, which described a mighty Greek king who would conquer the Persian Empire. This is cited as a reason for sparing Jerusalem. + +In Hindi and Urdu, the name "Sikandar", derived from the Persian name for Alexander, denotes a rising young talent, and the Delhi Sultanate ruler Aladdin Khalji stylized himself as "Sikandar-i-Sani" (the Second Alexander the Great). In medieval India, Turkic and Afghan sovereigns from the Iranian-cultured region of Central Asia brought positive cultural connotations of Alexander to the Indian subcontinent, resulting in the efflorescence of Sikandernameh (Alexander Romances) written by Indo-Persian poets such as Amir Khusrow and the prominence of Alexander the Great as a popular subject in Mughal-era Persian miniatures. In medieval Europe, Alexander the Great was revered as a member of the Nine Worthies, a group of heroes whose lives were believed to encapsulate all the ideal qualities of chivalry. During the first Italian campaign of the French Revolutionary Wars, in a question from Bourrienne, asking whether he gave his preference to Alexander or Caesar, Napoleon said that he places Alexander The Great in the first rank, the main reason being his campaign on Asia. + +In the Greek Anthology, there are poems referring to Alexander. + +Throughout time, art objects related to Alexander were being created. In addition to speech works, sculptures and paintings, in modern times Alexander is still the subject of musical and cinematic works. The song 'Alexander the Great' by the British heavy metal band Iron Maiden is indicative. Some films that have been shot with the theme of Alexander are: + Sikandar (1941), an Indian production directed by Sohrab Modi about the conquest of India by Alexander + Alexander the Great (1956), produced by MGM and starring Richard Burton + Sikandar-e-Azam (1965), an Indian production directed by Kedar Kapoor + Alexander (2004), directed by Oliver Stone, starring Colin Farrell + +There are also many references to other movies and TV series. + +Newer novels about Alexander are: + +The trilogy "Alexander the Great" by Valerio Massimo Manfredi consisting of "The son of the dream", "The sand of Amon", and "The ends of the world". +The trilogy of Mary Renault consisting of "Fire from Heaven", "The Persian Boy" and "Funeral Games". + The Virtues of War, about Alexander the Great (2004), and "* The Afghan Campaign, about Alexander the Great's conquests in Afghanistan (2006), " by Steven Pressfield. + +Irish playwright Aubrey Thomas de Vere wrote Alexander the Great, a Dramatic Poem. + +Historiography + +Apart from a few inscriptions and fragments, texts written by people who actually knew Alexander or who gathered information from men who served with Alexander were all lost. Contemporaries who wrote accounts of his life included Alexander's campaign historian Callisthenes; Alexander's generals Ptolemy and Nearchus; Aristobulus, a junior officer on the campaigns; and Onesicritus, Alexander's chief helmsman. Their works are lost, but later works based on these original sources have survived. The earliest of these is Diodorus Siculus (1st century BC), followed by Quintus Curtius Rufus (mid-to-late 1st century AD), Arrian (1st to 2nd century AD), the biographer Plutarch (1st to 2nd century AD), and finally Justin, whose work dated as late as the 4th century. Of these, Arrian is generally considered the most reliable, given that he used Ptolemy and Aristobulus as his sources, closely followed by Diodorus. + +See also + + Ancient Macedonian army + Military tactics of Alexander the Great + Bucephalus + Chronology of European exploration of Asia + Theories about Alexander the Great in the Quran + Ptolemaic cult of Alexander the Great + Gates of Alexander + List of biblical figures identified in extra-biblical sources + List of people known as The Great + +References + +Notes + +Citations + +Sources + +Primary sources + + + + + + . + +Secondary sources + +Further reading + + + + + + + + + + + + + + + + + + + , also (1974) New York: E.

He argued that human knowledge of the world is limited both by the human nervous system and the languages humans have developed, and thus no one can have direct access to reality, given that the most we can know is that which is filtered through the brain's responses to reality. His best known dictum is "The map is not the territory". + +Early life and career + +Born in Warsaw, Vistula Country, which was then part of the Russian Empire, Korzybski belonged to an aristocratic Polish family whose members had worked as mathematicians, scientists, and engineers for generations. He learned the Polish language at home and the Russian language in schools, and having a French and German governess, he became fluent in four languages as a child. + +Korzybski studied engineering at the Warsaw University of Technology. During the First World War (1914–1918) Korzybski served as an intelligence officer in the Russian Army. After being wounded in a leg and suffering other injuries, he moved to North America in 1916 (first to Canada, then to the United States) to coordinate the shipment of artillery to Russia. He also lectured to Polish-American audiences about the conflict, promoting the sale of war bonds. After the war he decided to remain in the United States, becoming a naturalized citizen in 1940. He met Mira Edgerly, a painter of portraits on ivory, shortly after the 1918 Armistice; They married in January 1919; the marriage lasted until his death. + +E. P. Dutton published Korzybski's first book, Manhood of Humanity, in 1921. In this work he proposed and explained in detail a new theory of humankind: mankind as a "time-binding" class of life (humans perform time binding by the transmission of knowledge and abstractions through time which become accreted in cultures). +In 1925 and 1926, Korzybski observed psychiatric patients at St. Elizabeth's hospital in D.C. under the supervision of William Alanson White. + +General semantics +Korzybski's work culminated in the initiation of a discipline that he named general semantics (GS). This should not be confused with semantics. The basic principles of general semantics, which include time-binding, are described in the publication Science and Sanity, published in 1933. In 1938, Korzybski founded the Institute of General Semantics in Chicago. The post-World War II housing shortage in Chicago cost him the institute's building lease, so in 1946 he moved the institute to Lakeville, Connecticut, U.S., where he directed it until his death in 1950. + +Korzybski maintained that humans are limited in what they know by (1) the structure of their nervous systems, and (2) the structure of their languages. Humans cannot experience the world directly, but only through their "abstractions" (nonverbal impressions or "gleanings" derived from the nervous system, and verbal indicators expressed and derived from language). These sometimes mislead us about what is the truth. Our understanding sometimes lacks similarity of structure with what is actually happening. + +He sought to train our awareness of abstracting, using techniques he had derived from his study of mathematics and science. He called this awareness, this goal of his system, "consciousness of abstracting". His system included the promotion of attitudes such as "I don't know; let's see," in order that we may better discover or reflect on its realities as revealed by modern science. Another technique involved becoming inwardly and outwardly quiet, an experience he termed, "silence on the objective levels". + +"To be" +Many devotees and critics of Korzybski reduced his rather complex system to a simple matter of what he said about the verb form "is" of the general verb "to be." His system, however, is based primarily on such terminology as the different "orders of abstraction," and formulations such as "consciousness of abstracting." The contention that Korzybski opposed the use of the verb "to be" would be a profound exaggeration. + +He thought that certain uses of the verb "to be", called the "is of identity" and the "is of predication", were faulty in structure, e.g., a statement such as, "Elizabeth is a fool" (said of a person named "Elizabeth" who has done something that we regard as foolish). In Korzybski's system, one's assessment of Elizabeth belongs to a higher order of abstraction than Elizabeth herself. Korzybski's remedy was to deny identity; in this example, to be aware continually that "Elizabeth" is not what we call her. We find Elizabeth not in the verbal domain, the world of words, but the nonverbal domain (the two, he said, amount to different orders of abstraction). This was expressed by Korzybski's most famous premise, "the map is not the territory". Note that this premise uses the phrase "is not", a form of "to be"; this and many other examples show that he did not intend to abandon "to be" as such. In fact, he said explicitly that there were no structural problems with the verb "to be" when used as an auxiliary verb or when used to state existence or location. It was even acceptable at times to use the faulty forms of the verb "to be," as long as one was aware of their structural limitations. + +Anecdotes +One day, Korzybski was giving a lecture to a group of students, and he interrupted the lesson suddenly in order to retrieve a packet of biscuits, wrapped in white paper, from his briefcase. He muttered that he just had to eat something, and he asked the students on the seats in the front row if they would also like a biscuit. A few students took a biscuit. "Nice biscuit, don't you think," said Korzybski, while he took a second one. The students were chewing vigorously. Then he tore the white paper from the biscuits, in order to reveal the original packaging. On it was a big picture of a dog's head and the words "Dog Cookies." The students looked at the package, and were shocked. Two of them wanted to vomit, put their hands in front of their mouths, and ran out of the lecture hall to the toilet. "You see," Korzybski remarked, "I have just demonstrated that people don't just eat food, but also words, and that the taste of the former is often outdone by the taste of the latter." + +William Burroughs went to a Korzybski workshop in the autumn of 1939. He was 25 years old, and paid $40. His fellow students—there were 38 in all—included young Samuel I. Hayakawa (later to become a Republican member of the U.S. Senate) and Wendell Johnson (founder of the Monster Study). + +Influence +Korzybski was well received in numerous disciplines, as evidenced by the positive reactions from leading figures in the sciences and humanities in the 1940s and 1950s. These include author Robert A. Heinlein naming a character after him in his 1940 short story "Blowups Happen", and science fiction writer A. E. van Vogt in his novel "The World of Null-A", published in 1948. Korzybski's ideas influenced philosopher Alan Watts who used his phrase "the map is not the territory" in lectures. Writer Robert Anton Wilson was also deeply influenced by Korzybski's ideas. + +As reported in the third edition of Science and Sanity, in World War II the US Army used Korzybski's system to treat battle fatigue in Europe, under the supervision of Dr. Douglas M. Kelley, who went on to become the psychiatrist in charge of the Nazi war criminals at Nuremberg. + +Some of the General Semantics tradition was continued by Samuel I.

The player controls a single spaceship in an asteroid field which is periodically traversed by flying saucers. The object of the game is to shoot and destroy the asteroids and saucers, while not colliding with either, or being hit by the saucers' counter-fire. The game becomes harder as the number of asteroids increases. + +Asteroids was conceived during a meeting between Logg and Rains, who decided to use hardware developed by Howard Delman previously used for Lunar Lander. Asteroids was based on an unfinished game titled Cosmos; its physics model, control scheme, and gameplay elements were derived from Spacewar!, Computer Space, and Space Invaders and refined through trial and error. The game is rendered on a vector display in a two-dimensional view that wraps around both screen axes. + +Asteroids was one of the first major hits of the golden age of arcade games; the game sold 47,840 upright cabinets and 8,725 cocktail cabinets arcade cabinets and proved both popular with players and influential with developers. In the 1980s it was ported to Atari's home systems, and the Atari VCS version sold over three million copies. The game was widely imitated, and it directly influenced Defender, Gravitar, and many other video games. + +Gameplay + +The objective of Asteroids is to destroy asteroids and saucers. The player controls a triangular ship that can rotate left and right, fire shots straight forward, and thrust forward. Once the ship begins moving in a direction, it will continue in that direction for a time without player intervention unless the player applies thrust in a different direction. The ship eventually comes to a stop when not thrusting. The player can also send the ship into hyperspace, causing it to disappear and reappear in a random location on the screen, at the risk of self-destructing or appearing on top of an asteroid. + +Each level starts with a few large asteroids drifting in various directions on the screen. Objects wrap around screen edges – for instance, an asteroid that drifts off the top edge of the screen reappears at the bottom and continues moving in the same direction. As the player shoots asteroids, they break into smaller asteroids that move faster and are more difficult to hit. Smaller asteroids are also worth more points. Two flying saucers appear periodically on the screen; the "big saucer" shoots randomly and poorly, while the "small saucer" fires frequently at the ship. After reaching a score of 40,000, only the small saucer appears. As the player's score increases, the angle range of the shots from the small saucer diminishes until the saucer fires extremely accurately. Once the screen has been cleared of all asteroids and flying saucers, a new set of large asteroids appears, thus starting the next level. The game gets harder as the number of asteroids increases until after the score reaches a range between 40,000 and 60,000. The player starts with 3–5 lives upon game start and gains an extra life per 10,000 points. Play continues to the last ship lost, which ends the game. The machine "turns over" at 99,990 points, which is the maximum high score that can be achieved. + +Lurking exploit +In the original game design, saucers were supposed to begin shooting as soon as they appeared, but this was changed. Additionally, saucers can only aim at the player's ship on-screen; they are not capable of aiming across a screen boundary. These behaviors allow a "lurking" strategy, in which the player stays near the edge of the screen opposite the saucer. By keeping just one or two rocks in play, a player can shoot across the boundary and destroy saucers to accumulate points indefinitely with little risk of being destroyed. Arcade operators began to complain about losing revenue due to this exploit. In response, Atari issued a patched EPROM and, due to the impact of this exploit, Atari (and other companies) changed their development and testing policies to try to prevent future games from having such exploits. + +Development + +Concept +Asteroids was conceived by Lyle Rains and programmed by Ed Logg with collaborations from other Atari staff. Logg was impressed with the Atari Video Computer System (later called the Atari 2600), and he joined Atari's coin-op division to work on Dirt Bike, which was never released due to an unsuccessful field test. Paul Mancuso joined the development team as Asteroids technician and engineer Howard Delman contributed to the hardware. During a meeting in April 1979, Rains discussed Planet Grab, a multiplayer arcade game later renamed to Cosmos. Logg did not know the name of the game, thinking Computer Space as "the inspiration for the two-dimensional approach". Rains conceived of Asteroids as a mixture of Computer Space and Space Invaders, combining the two-dimensional approach of Computer Space with Space Invaders addictive gameplay of "completion" and "eliminate all threats". The unfinished game featured a giant, indestructible asteroid, so Rains asked Logg: "Well, why don’t we have a game where you shoot the rocks and blow them up?" In response, Logg described a similar concept where the player selectively shoots at rocks that break into smaller pieces. Both agreed on the concept. + +Hardware +Asteroids was implemented on hardware developed by Delman and is a vector game, in which the graphics are composed of lines drawn on a vector monitor. Rains initially wanted the game done in raster graphics, but Logg, experienced in vector graphics, suggested an XY monitor because the high image quality would permit precise aiming. The hardware is chiefly a MOS 6502 executing the game program, and QuadraScan, a high-resolution vector graphics processor developed by Atari and referred to as an "XY display system" and the "Digital Vector Generator (DVG)". + +The original design concepts for QuadraScan came out of Cyan Engineering, Atari's off-campus research lab in Grass Valley, California, in 1978. Cyan gave it to Delman, who finished the design and first used it for Lunar Lander. Logg received Delman's modified board with five buttons, 13 sound effects, and additional RAM, and he used it to develop Asteroids. The size of the board was 4 by 4 inches, and it was "linked up" to a monitor. + +Implementation +Logg modeled the player's ship, the five-button control scheme, and the game physics after Spacewar!, which he had played as a student at the University of California, Berkeley, but made several changes to improve playability. The ship was programmed into the hardware and rendered by the monitor, and it was configured to move with thrust and inertia. The hyperspace button was not placed near Logg's right thumb, which he was dissatisfied with, as he had a problem "tak[ing] his hand off the thrust button". Drawings of asteroids in various shapes were incorporated into the game. Logg copied the idea of a high score table with initials from Exidy's Star Fire. + +The two saucers were formulated to be different from each other. A steadily decreasing timer shortens intervals between saucer attacks to keep the player from not shooting asteroids and saucers. A "heartbeat" soundtrack quickens as the game progresses. The game does not have a sound chip. Delman created a hardware circuit for 13 sound effects by hand which was wired onto the board. + +A prototype of Asteroids was well received by several Atari staff and engineers, who "wander[ed] between labs, passing comment and stopping to play as they went". Logg was often asked when he would be leaving by employees eager to play the prototype, so he created a second prototype for staff to play. Atari tested the game in arcades in Sacramento, California, and also observed players during focus group sessions at Atari. Players used to Spacewar! struggled to maintain grip on the thrust button and requested a joystick; players accustomed to Space Invaders noted they get no break in the game. Logg and other engineers observed proceedings and documented comments in four pages. + +Asteroids slows down as the player gains 50–100 lives, because there is no limit to the number of lives displayed. The player can "lose" the game after more than 250 lives are collected. + +Ports +Asteroids was released for the Atari VCS (later renamed the Atari 2600) and Atari 8-bit family in 1981, then the Atari 7800 in 1986. A port for the Atari 5200, identical to the Atari 8-bit computer version, was in development in 1982, but was not published. The Atari 7800 version was a launch title and includes cooperative play; the asteroids have colorful textures and the "heartbeat" sound effect remains intact. + +Programmers Brad Stewart and Bob Smith were unable to fit the Atari VCS port into a 4 KB cartridge. It became the first game for the console to use bank switching, a technique that increases ROM size from 4 KB to 8 KB. + +Reception +Asteroids was immediately successful upon release. It displaced Space Invaders by popularity in the United States and became Atari's best selling arcade game of all time, with over 70,000 units sold. Atari earned an estimated $150 million in sales from the game, and arcade operators earned a further $500 million from coin drops. Atari had been in the process of manufacturing another vector game, Lunar Lander, but demand for Asteroids was so high "that several hundred Asteroids games were shipped in Lunar Lander cabinets". Asteroids was so popular that some video arcade operators had to install large boxes to hold the number of coins spent by players. It replaced Space Invaders at the top of the US RePlay amusement arcade charts in April 1980, though Space Invaders remained the top game at street locations. Asteroids went on to become the highest-grossing arcade video game of 1980 in the United States, dethroning Space Invaders. It shipped 70,000 arcade units worldwide in 1980, including over 60,000 sold in the United States that year, and grossed about worldwide ( adjusted for inflation) by 1980. The game remained at the top of the US RePlay charts through March 1981. However, the game did not perform as well overseas in Europe and Asia. It sold 30,000 arcade units overseas, for a total of 100,000 arcade units sold worldwide. Atari manufactured 76,312 units from its US and Ireland plants, including 21,394 Asteroids Deluxe units. It was a commercial failure in Japan when it released there in 1980, partly due to its complex controls and partly due to the Japanese market beginning to lose interest in space shoot 'em ups at the time. + +Asteroids received positive reviews from video game critics and has been regarded as Logg's magnum opus. Richard A. Edwards reviewed the 1981 Asteroids home cartridge in The Space Gamer No. 46. Edwards commented that "this home cartridge is a virtual duplicate of the ever-popular Atari arcade game. [...] If blasting asteroids is the thing you want to do then this is the game, but at this price I can't wholeheartedly recommend it". Video Games Player magazine reviewed the Atari VCS version, rating the graphics and sound a B, while giving the game an overall B+ rating. Electronic Fun with Computers & Games magazine gave the Atari VCS version an A rating. + +William Cassidy, writing for GameSpy's "Classic Gaming", noticed its innovations, including being one of the first video games to track initials and allow players to enter their initials for appearing in the top 10 high scores, and commented, "the vector graphics fit the futuristic outer space theme very well". In 1995, Flux magazine ranked the arcade version 11th on their "Top 100 Video Games." In 1996, Next Generation listed it as number 39 on their "Top 100 Games of All Time", particularly lauding the control dynamics which require "the constant juggling of speed, positioning, and direction". In 1999, Next Generation listed Asteroids as number 29 on their "Top 50 Games of All Time", commenting that "Asteroids was a classic the day it was released, and it has never lost any of its appeal". Asteroids was ranked fourth on Retro Gamers list of "Top 25 Arcade Games"; the Retro Gamer staff cited its simplicity and the lack of a proper ending as allowances of revisiting the game. In 2012, Asteroids was listed on Time All-Time 100 greatest video games list. Entertainment Weekly named Asteroids one of the top ten games for the Atari 2600 in 2013. It was added to the Museum of Modern Art's collection of video games. In 2021, The Guardian listed Asteroids as the second greatest video game of the 1970s, just below Galaxian (1979). By contrast, in March 1983 the Atari 8-bit port of Asteroids won sixth place in Softlines Dog of the Year awards "for badness in computer games", Atari division, based on reader submissions. + +Usage of the names of Saturday Night Live characters "Mr. Bill" and "Sluggo" to refer to the saucers in an Esquire article about the game led to Logg receiving a cease and desist letter from a lawyer with the "Mr. Bill Trademark". + +Legacy + +Arcade sequels +Released in 1981, Asteroids Deluxe was the first sequel to Asteroids. Dave Shepperd edited the code and made enhancements to the game without Logg's involvement. The onscreen objects are tinted blue, and hyperspace is replaced by a shield that depletes when used. The asteroids rotate, and new "killer satellite" enemies break into smaller ships that home in on the player's position. The arcade machine's monitor displays vector graphics overlaying a holographic backdrop. The game is more difficult than the original and enables saucers to shoot across the screen boundary, eliminating the lurking strategy for high scores in the original. + +Space Duel, released in arcades in 1982, replaces the rocks with colorful geometric shapes and adds cooperative two-player gameplay. + +1987's Blasteroids includes "power-ups, ship morphing, branching levels, bosses, and the ability to dock your ships in multiplayer for added firepower". Blasteroids uses raster graphics instead of vectors. + +Re-releases +The game is half of the Atari Lynx pairing Super Asteroids & Missile Command, and included in the 1993 Microsoft Arcade compilation. + +Activision published an enhanced version of Asteroids for the PlayStation (1998), Nintendo 64 (1999), Microsoft Windows (1998), Game Boy Color (1999), and Mac (2000). The Atari Flashback series of dedicated video game consoles have included both the 2600 and the arcade versions of Asteroids. + +Published by Crave Entertainment on December 14, 1999, Asteroids Hyper 64 made the ship and asteroids 3D and added new weapons and a multiplayer mode. + +A technical demo of Asteroids was developed by iThink for the Atari Jaguar but was never released. Unofficially referred to as Asteroids 2000, it was demonstrated at E-JagFest 2000. + +In 2001, Infogrames released Atari Anniversary Edition for the Dreamcast, PlayStation, and Microsoft Windows. Developed by Digital Eclipse, it includes emulated versions of Asteroids and other games. The arcade and Atari 2600 versions of Asteroids were included in Atari Anthology for both Xbox and PlayStation 2. + +Released on November 28, 2007, the Xbox Live Arcade port of Asteroids has revamped HD graphics along with an added intense "throttle monkey" mode. The arcade and 2600 versions were made available through Microsofts Game Room service in 2010. Glu Mobile released an enhanced mobile phone port. + +Asteroids is included on Atari Greatest Hits Volume 1 for the Nintendo DS. + +An updated version of the game was announced in 2018 for the Intellivision Amico. + +Both the Atari 2600 and Atari 7800 versions of the game was included on Atari Collection 1 and 2 in 2020 for the Evercade. + +A remake, Asteroids: Recharged, was released in December 2021 for the Nintendo Switch, PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S. It was developed by Adamvision Studios and SneakyBox. + +Clones +Quality Software's Asteroids in Space (1980) was one of the best selling games for the Apple II and voted one of the most popular software titles of 1978-80 by Softalk magazine. +In December 1981, Byte reviewed eight Asteroids clones for home computers. Three clones for the Apple II were reviewed together in the 1982 Creative Computing Software Buyers Guide: The Asteroid Field, Asteron, and Apple-Oids. In the last of these, the asteroids are in the shape of apples. Two independent clones, Asteroid for the Apple II and Fasteroids for TRS-80, were renamed to Planetoids and sold by Adventure International. Others clones include Acornsoft's Meteors, Moons of Jupiter for the VIC-20, MineStorm for the Vectrex, and Quicksilva's Meteor Storm for the ZX Spectrum which uses speech synthesis. A poorly implemented Asteroids clone for the VIC-20, published by Bug-Byte, motivated Jeff Minter to found Llamasoft. + +The Intellivision game Meteor! was cancelled to avoid a lawsuit for being too similar to Asteroids and was reworked as Astrosmash. The game borrows elements from Asteroids and Space Invaders. + +Proposed film adaptation +On July 2, 2009, Universal Pictures offered Emmerich the option to direct the film adaptation of Asteroids, with Matt Lopez writing the script and Lorenzo di Bonaventura will produce the film adaptation. On June 8, 2011, Universal offered Roland Emmerich the option to direct the film adaptation with Lopez and di Bonaventura still attached to write and produce the film adaptation, respectively, which Emmerich passed on directing, while Evan Spiliotopoulos and F. Scott Frazier were hired to rewrite the screenplay. + +World records +On February 6, 1982, Leo Daniels of Carolina Beach, North Carolina, set a world record score of 40,101,910 points. On November 13 of the same year, 15-year-old Scott Safran of Cherry Hill, New Jersey, set a new record at 41,336,440 points. In 1998, to congratulate Safran on his accomplishment, the Twin Galaxies Intergalactic Scoreboard searched for him for four years until 2002, when it was discovered that he had died in an accident in 1989. In a ceremony in Philadelphia on April 27, 2002, Walter Day of Twin Galaxies presented an award to the surviving members of Safran's family, commemorating his achievement. On April 5, 2010, John McAllister broke Safran's record with a high score of 41,838,740 in a 58-hour Internet livestream. + +References + +External links + + at Atari + + + + + + +1979 video games +Arcade video games +Atari 2600 games +Atari 7800 games +Atari 8-bit family games +Atari arcade games +Atari Lynx games +Cancelled Atari 5200 games +Cancelled Atari Jaguar games +Ed Logg games +Fiction about asteroids +Game Boy games +Game Boy Color games +Multidirectional shooters +Multiplayer and single-player video games +Science fiction video games +Sega arcade games +Taito arcade games +Xbox 360 games +Xbox 360 Live Arcade games +Vector arcade video games +Video games developed in the United States +Asparagales (asparagoid lilies) is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species. + +The order is clearly circumscribed on the basis of molecular phylogenetics, but it is difficult to define morphologically since its members are structurally diverse. Most species of Asparagales are herbaceous perennials, although some are climbers and some are tree-like. The order also contains many geophytes (bulbs, corms, and various kinds of tuber). According to telomere sequence, at least two evolutionary switch-points happened within the order. The basal sequence is formed by TTTAGGG like in the majority of higher plants. Basal motif was changed to vertebrate-like TTAGGG and finally, the most divergent motif CTCGGTTATGGG appears in Allium. One of the defining characteristics (synapomorphies) of the order is the presence of phytomelanin, a black pigment present in the seed coat, creating a dark crust. Phytomelanin is found in most families of the Asparagales (although not in Orchidaceae, thought to be the sister-group of the rest of the order). + +The leaves of almost all species form a tight rosette, either at the base of the plant or at the end of the stem, but occasionally along the stem. The flowers are not particularly distinctive, being 'lily type', with six tepals and up to six stamina. + +The order is thought to have first diverged from other related monocots some 120–130 million years ago (early in the Cretaceous period), although given the difficulty in classifying the families involved, estimates are likely to be uncertain. + +From an economic point of view, the order Asparagales is second in importance within the monocots only to the order Poales (which includes grasses and cereals). Species are used as food and flavourings (e.g. onion, garlic, leek, asparagus, vanilla, saffron), in medicinal or cosmetic applications (Aloe), as cut flowers (e.g. freesia, gladiolus, iris, orchids), and as garden ornamentals (e.g. day lilies, lily of the valley, Agapanthus). + +Description + +Although most species in the order are herbaceous, some no more than 15 cm high, there are a number of climbers (e.g., some species of Asparagus), as well as several genera forming trees (e.g. Agave, Cordyline, Yucca, Dracaena, Aloe ), which can exceed 10 m in height. Succulent genera occur in several families (e.g. Aloe). + +Almost all species have a tight cluster of leaves (a rosette), either at the base of the plant or at the end of a more-or-less woody stem as with Yucca. In some cases, the leaves are produced along the stem. The flowers are in the main not particularly distinctive, being of a general 'lily type', with six tepals, either free or fused from the base and up to six stamina. They are frequently clustered at the end of the plant stem. + +The Asparagales are generally distinguished from the Liliales by the lack of markings on the tepals, the presence of septal nectaries in the ovaries, rather than the bases of the tepals or stamen filaments, and the presence of secondary growth. They are generally geophytes, but with linear leaves, and a lack of fine reticular venation. + +The seeds characteristically have the external epidermis either obliterated (in most species bearing fleshy fruit), or if present, have a layer of black carbonaceous phytomelanin in species with dry fruits (nuts). The inner part of the seed coat is generally collapsed, in contrast to Liliales whose seeds have a well developed outer epidermis, lack phytomelanin, and usually display a cellular inner layer. + +The orders which have been separated from the old Liliales are difficult to characterize. No single morphological character appears to be diagnostic of the order Asparagales. + The flowers of Asparagales are of a general type among the lilioid monocots. Compared to Liliales, they usually have plain tepals without markings in the form of dots. If nectaries are present, they are in the septa of the ovaries rather than at the base of the tepals or stamens. + Those species which have relatively large dry seeds have a dark, crust-like (crustose) outer layer containing the pigment phytomelan. However, some species with hairy seeds (e.g. Eriospermum, family Asparagaceae s.l.), berries (e.g. Maianthemum, family Asparagaceae s.l.), or highly reduced seeds (e.g. orchids) lack this dark pigment in their seed coats. Phytomelan is not unique to Asparagales (i.e. it is not a synapomorphy) but it is common within the order and rare outside it. The inner portion of the seed coat is usually completely collapsed. In contrast, the morphologically similar seeds of Liliales have no phytomelan, and usually retain a cellular structure in the inner portion of the seed coat. + Most monocots are unable to thicken their stems once they have formed, since they lack the cylindrical meristem present in other angiosperm groups. Asparagales have a method of secondary thickening which is otherwise only found in Dioscorea (in the monocot order Disoscoreales). In a process called 'anomalous secondary growth', they are able to create new vascular bundles around which thickening growth occurs. Agave, Yucca, Aloe, Dracaena, Nolina and Cordyline can become massive trees, albeit not of the height of the tallest dicots, and with less branching. Other genera in the order, such as Lomandra and Aphyllanthes, have the same type of secondary growth but confined to their underground stems. + Microsporogenesis (part of pollen formation) distinguishes some members of Asparagales from Liliales. Microsporogenesis involves a cell dividing twice (meiotically) to form four daughter cells. There are two kinds of microsporogenesis: successive and simultaneous (although intermediates exist). In successive microsporogenesis, walls are laid down separating the daughter cells after each division. In simultaneous microsporogenesis, there is no wall formation until all four cell nuclei are present. Liliales all have successive microsporogenesis, which is thought to be the primitive condition in monocots. It seems that when the Asparagales first diverged they developed simultaneous microsporogenesis, which the 'lower' Asparagales families retain. However, the 'core' Asparagales (see Phylogenetics ) have reverted to successive microsporogenesis. + The Asparagales appear to be unified by a mutation affecting their telomeres (a region of repetitive DNA at the end of a chromosome). The typical 'Arabidopsis-type' sequence of bases has been fully or partially replaced by other sequences, with the 'human-type' predominating. + Other apomorphic characters of the order according to Stevens are: the presence of chelidonic acid, anthers longer than wide, tapetal cells bi- to tetra-nuclear, tegmen not persistent, endosperm helobial, and loss of mitochondrial gene sdh3. + +Taxonomy + +As circumscribed within the Angiosperm Phylogeny Group system Asparagales is the largest order within the monocotyledons, with 14 families, 1,122 genera and about 25,000–42,000 species, thus accounting for about 50% of all monocots and 10–15% of the flowering plants (angiosperms). The attribution of botanical authority for the name Asparagales belongs to Johann Heinrich Friedrich Link (1767–1851) who coined the word 'Asparaginae' in 1829 for a higher order taxon that included Asparagus although Adanson and Jussieau had also done so earlier (see History). Earlier circumscriptions of Asparagales attributed the name to Bromhead (1838), who had been the first to use the term 'Asparagales'. + +History + +Pre-Darwinian +The type genus, Asparagus, from which the name of the order is derived, was described by Carl Linnaeus in 1753, with ten species. He placed Asparagus within the Hexandria Monogynia (six stamens, one carpel) in his sexual classification in the Species Plantarum. The majority of taxa now considered to constitute Asparagales have historically been placed within the very large and diverse family, Liliaceae. The family Liliaceae was first described by Michel Adanson in 1763, and in his taxonomic scheme he created eight sections within it, including the Asparagi with Asparagus and three other genera. The system of organising genera into families is generally credited to Antoine Laurent de Jussieu who formally described both the Liliaceae and the type family of Asparagales, the Asparagaceae, as Lilia and Asparagi, respectively, in 1789. Jussieu established the hierarchical system of taxonomy (phylogeny), placing Asparagus and related genera within a division of Monocotyledons, a class (III) of Stamina Perigynia and 'order' Asparagi, divided into three subfamilies. The use of the term Ordo (order) at that time was closer to what we now understand as Family, rather than Order. In creating his scheme he used a modified form of Linnaeus' sexual classification but using the respective topography of stamens to carpels rather than just their numbers. While De Jussieu's Stamina Perigynia also included a number of 'orders' that would eventually form families within the Asparagales such as the Asphodeli (Asphodelaceae), Narcissi (Amaryllidaceae) and Irides (Iridaceae), the remainder are now allocated to other orders. Jussieu's Asparagi soon came to be referred to as Asparagacées in the French literature (Latin: Asparagaceae). Meanwhile, the 'Narcissi' had been renamed as the 'Amaryllidées' (Amaryllideae) in 1805, by Jean Henri Jaume Saint-Hilaire, using Amaryllis as the type species rather than Narcissus, and thus has the authority attribution for Amaryllidaceae. In 1810, Brown proposed that a subgroup of Liliaceae be distinguished on the basis of the position of the ovaries and be referred to as Amaryllideae and in 1813 de Candolle described Liliacées Juss. and Amaryllidées Brown as two quite separate families. + +The literature on the organisation of genera into families and higher ranks became available in the English language with Samuel Frederick Gray's A natural arrangement of British plants (1821). Gray used a combination of Linnaeus' sexual classification and Jussieu's natural classification to group together a number of families having in common six equal stamens, a single style and a perianth that was simple and petaloid, but did not use formal names for these higher ranks. Within the grouping he separated families by the characteristics of their fruit and seed. He treated groups of genera with these characteristics as separate families, such as Amaryllideae, Liliaceae, Asphodeleae and Asparageae. + +The circumscription of Asparagales has been a source of difficulty for many botanists from the time of John Lindley (1846), the other important British taxonomist of the early nineteenth century. In his first taxonomic work, An Introduction to the Natural System of Botany (1830) he partly followed Jussieu by describing a subclass he called Endogenae, or Monocotyledonous Plants (preserving de Candolle's Endogenæ phanerogamæ) divided into two tribes, the Petaloidea and Glumaceae. He divided the former, often referred to as petaloid monocots, into 32 orders, including the Liliaceae (defined narrowly), but also most of the families considered to make up the Asparagales today, including the Amaryllideae. + +By 1846, in his final scheme Lindley had greatly expanded and refined the treatment of the monocots, introducing both an intermediate ranking (Alliances) and tribes within orders (i.e. families). Lindley placed the Liliaceae within the Liliales, but saw it as a paraphyletic ("catch-all") family, being all Liliales not included in the other orders, but hoped that the future would reveal some characteristic that would group them better. The order Liliales was very large and included almost all monocotyledons with colourful tepals and without starch in their endosperm (the lilioid monocots). The Liliales was difficult to divide into families because morphological characters were not present in patterns that clearly demarcated groups. This kept the Liliaceae separate from the Amaryllidaceae (Narcissales). Of these, Liliaceae was divided into eleven tribes (with 133 genera) and Amaryllidaceae into four tribes (with 68 genera), yet both contained many genera that would eventually segregate to each other's contemporary orders (Liliales and Asparagales respectively). The Liliaceae would be reduced to a small 'core' represented by the tribe Tulipae, while large groups such Scilleae and Asparagae would become part of Asparagales either as part of the Amaryllidaceae or as separate families. While of the Amaryllidaceae, the Agaveae would be part of Asparagaceae but the Alstroemeriae would become a family within the Liliales. + +The number of known genera (and species) continued to grow and by the time of the next major British classification, that of the Bentham & Hooker system in 1883 (published in Latin) several of Lindley's other families had been absorbed into the Liliaceae. They used the term 'series' to indicate suprafamilial rank, with seven series of monocotyledons (including Glumaceae), but did not use Lindley's terms for these. However, they did place the Liliaceous and Amaryllidaceous genera into separate series. The Liliaceae were placed in series Coronariae, while the Amaryllideae were placed in series Epigynae. The Liliaceae now consisted of twenty tribes (including Tulipeae, Scilleae and Asparageae), and the Amaryllideae of five (including Agaveae and Alstroemerieae). An important addition to the treatment of the Liliaceae was the recognition of the Allieae as a distinct tribe that would eventually find its way to the Asparagales as the subfamily Allioideae of the Amaryllidaceae. + +Post-Darwinian +The appearance of Charles Darwin's Origin of Species in 1859 changed the way that taxonomists considered plant classification, incorporating evolutionary information into their schemata. The Darwinian approach led to the concept of phylogeny (tree-like structure) in assembling classification systems, starting with Eichler. Eichler, having established a hierarchical system in which the flowering plants (angiosperms) were divided into monocotyledons and dicotyledons, further divided into former into seven orders. Within the Liliiflorae were seven families, including Liliaceae and Amaryllidaceae. Liliaceae included Allium and Ornithogalum (modern Allioideae) and Asparagus. + +Engler, in his system developed Eichler's ideas into a much more elaborate scheme which he treated in a number of works including Die Natürlichen Pflanzenfamilien (Engler and Prantl 1888) and Syllabus der Pflanzenfamilien (1892–1924). In his treatment of Liliiflorae the Liliineae were a suborder which included both families Liliaceae and Amaryllidaceae. The Liliaceae had eight subfamilies and the Amaryllidaceae four. In this rearrangement of Liliaceae, with fewer subdivisions, the core Liliales were represented as subfamily Lilioideae (with Tulipae and Scilleae as tribes), the Asparagae were represented as Asparagoideae and the Allioideae was preserved, representing the alliaceous genera. Allieae, Agapantheae and Gilliesieae were the three tribes within this subfamily. In the Amaryllidaceae, there was little change from the Bentham & Hooker. A similar approach was adopted by Wettstein. + +Twentieth century +In the twentieth century the Wettstein system (1901–1935) placed many of the taxa in an order called 'Liliiflorae'. Next Johannes Paulus Lotsy (1911) proposed dividing the Liliiflorae into a number of smaller families including Asparagaceae. Then Herbert Huber (1969, 1977), following Lotsy's example, proposed that the Liliiflorae be split into four groups including the 'Asparagoid' Liliiflorae. +The widely used Cronquist system (1968–1988) used the very broadly defined order Liliales. + +These various proposals to separate small groups of genera into more homogeneous families made little impact till that of Dahlgren (1985) incorporating new information including synapomorphy. Dahlgren developed Huber's ideas further and popularised them, with a major deconstruction of existing families into smaller units. They created a new order, calling it Asparagales. This was one of five orders within the superorder Liliiflorae. Where Cronquist saw one family, Dahlgren saw forty distributed over three orders (predominantly Liliales and Asparagales). Over the 1980s, in the context of a more general review of the classification of angiosperms, the Liliaceae were subjected to more intense scrutiny. By the end of that decade, the Royal Botanic Gardens at Kew, the British Museum of Natural History and the Edinburgh Botanical Gardens formed a committee to examine the possibility of separating the family at least for the organization of their herbaria. That committee finally recommended that 24 new families be created in the place of the original broad Liliaceae, largely by elevating subfamilies to the rank of separate families. + +Phylogenetics + +The order Asparagales as currently circumscribed has only recently been recognized in classification systems, through the advent of phylogenetics. The 1990s saw considerable progress in plant phylogeny and phylogenetic theory, enabling a phylogenetic tree to be constructed for all of the flowering plants. The establishment of major new clades necessitated a departure from the older but widely used classifications such as Cronquist and Thorne based largely on morphology rather than genetic data. This complicated the discussion about plant evolution and necessitated a major restructuring. rbcL gene sequencing and cladistic analysis of monocots had redefined the Liliales in 1995. from four morphological orders sensu Dahlgren. The largest clade representing the Liliaceae, all previously included in Liliales, but including both the Calochortaceae and Liliaceae sensu Tamura. This redefined family, that became referred to as core Liliales, but corresponded to the emerging circumscription of the Angiosperm Phylogeny Group (1998). + +Phylogeny and APG system +The 2009 revision of the Angiosperm Phylogeny Group system, APG III, places the order in the clade monocots. + +From the Dahlgren system of 1985 onwards, studies based mainly on morphology had identified the Asparagales as a distinct group, but had also included groups now located in Liliales, Pandanales and Zingiberales. Research in the 21st century has supported the monophyly of Asparagales, based on morphology, 18S rDNA, and other DNA sequences, although some phylogenetic reconstructions based on molecular data have suggested that Asparagales may be paraphyletic, with Orchidaceae separated from the rest. Within the monocots, Asparagales is the sister group of the commelinid clade. + +This cladogram shows the placement of Asparagales within the orders of Lilianae sensu Chase & Reveal (monocots) based on molecular phylogenetic evidence. The lilioid monocot orders are bracketed, namely Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales. These constitute a paraphyletic assemblage, that is groups with a common ancestor that do not include all direct descendants (in this case commelinids as the sister group to Asparagales); to form a clade, all the groups joined by thick lines would need to be included. While Acorales and Alismatales have been collectively referred to as "alismatid monocots" (basal or early branching monocots), the remaining clades (lilioid and commelinid monocots) have been referred to as the "core monocots". The relationship between the orders (with the exception of the two sister orders) is pectinate, that is diverging in succession from the line that leads to the commelinids. Numbers indicate crown group (most recent common ancestor of the sampled species of the clade of interest) divergence times in mya (million years ago). + +Subdivision +A phylogenetic tree for the Asparagales, generally to family level, but including groups which were recently and widely treated as families but which are now reduced to subfamily rank, is shown below. + +The tree shown above can be divided into a basal paraphyletic group, the 'lower Asparagales (asparagoids)', from Orchidaceae to Asphodelaceae, and a well-supported monophyletic group of 'core Asparagales' (higher asparagoids), comprising the two largest families, Amaryllidaceae sensu lato and Asparagaceae sensu lato. + +Two differences between these two groups (although with exceptions) are: the mode of microsporogenesis and the position of the ovary. The 'lower Asparagales' typically have simultaneous microsporogenesis (i.e. cell walls develop only after both meiotic divisions), which appears to be an apomorphy within the monocots, whereas the 'core Asparagales' have reverted to successive microsporogenesis (i.e. cell walls develop after each division). The 'lower Asparagales' typically have an inferior ovary, whereas the 'core Asparagales' have reverted to a superior ovary. A 2002 morphological study by Rudall treated possessing an inferior ovary as a synapomorphy of the Asparagales, stating that reversions to a superior ovary in the 'core Asparagales' could be associated with the presence of nectaries below the ovaries. However, Stevens notes that superior ovaries are distributed among the 'lower Asparagales' in such a way that it is not clear where to place the evolution of different ovary morphologies. The position of the ovary seems a much more flexible character (here and in other angiosperms) than previously thought. + +Changes to family structure in APG III +The APG III system when it was published in 2009, greatly expanded the families Xanthorrhoeaceae, Amaryllidaceae, and Asparagaceae. Thirteen of the families of the earlier APG II system were thereby reduced to subfamilies within these three families. The expanded Xanthorrhoeaceae is now called "Asphodelaceae". The APG II families (left) and their equivalent APG III subfamilies (right) are as follows: + +Structure of Asparagales + +Orchid clade +Orchidaceae is possibly the largest family of all angiosperms (only Asteraceae might - or might not - be more speciose) and hence by far the largest in the order. The Dahlgren system recognized three families of orchids, but DNA sequence analysis later showed that these families are polyphyletic and so should be combined. Several studies suggest (with high bootstrap support) that Orchidaceae is the sister of the rest of the Asparagales. Other studies have placed the orchids differently in the phylogenetic tree, generally among the Boryaceae-Hypoxidaceae clade. The position of Orchidaceae shown above seems the best current hypothesis, but cannot be taken as confirmed. + +Orchids have simultaneous microsporogenesis and inferior ovaries, two characters that are typical of the 'lower Asparagales'. However, their nectaries are rarely in the septa of the ovaries, and most orchids have dust-like seeds, atypical of the rest of the order. (Some members of Vanilloideae and Cypripedioideae have crustose seeds, probably associated with dispersal by birds and mammals that are attracted by fermenting fleshy fruit releasing fragrant compounds, e.g. vanilla.) + +In terms of the number of species, Orchidaceae diversification is remarkable. However, although the other Asparagales may be less rich in species, they are more variable morphologically, including tree-like forms. + +Boryaceae to Hypoxidaceae +The four families excluding Boryaceae form a well-supported clade in studies based on DNA sequence analysis. All four contain relatively few species, and it has been suggested that they be combined into one family under the name Hypoxidaceae sensu lato. The relationship between Boryaceae (which includes only two genera, Borya and Alania), and other Asparagales has remained unclear for a long time. The Boryaceae are mycorrhizal, but not in the same way as orchids. Morphological studies have suggested a close relationship between Boryaceae and Blandfordiaceae. There is relatively low support for the position of Boryaceae in the tree shown above. + +Ixioliriaceae to Xeronemataceae +The relationship shown between Ixioliriaceae and Tecophilaeaceae is still unclear. Some studies have supported a clade of these two families, others have not. The position of Doryanthaceae has also varied, with support for the position shown above, but also support for other positions. + +The clade from Iridaceae upwards appears to have stronger support. All have some genetic characteristics in common, having lost Arabidopsis-type telomeres. Iridaceae is distinctive among the Asparagales in the unique structure of the inflorescence (a rhipidium), the combination of an inferior ovary and three stamens, and the common occurrence of unifacial leaves whereas bifacial leaves are the norm in other Asparagales. + +Members of the clade from Iridaceae upwards have infra-locular septal nectaries, which Rudall interpreted as a driver towards secondarily superior ovaries. + +Asphodelaceae + 'core Asparagales' +The next node in the tree (Xanthorrhoeaceae sensu lato + the 'core Asparagales') has strong support. 'Anomalous' secondary thickening occurs among this clade, e.g. in Xanthorrhoea (family Asphodelaceae) and Dracaena (family Asparagaceae sensu lato), with species reaching tree-like proportions. + +The 'core Asparagales', comprising Amaryllidaceae sensu lato and Asparagaceae sensu lato, are a strongly supported clade, as are clades for each of the families. Relationships within these broadly defined families appear less clear, particularly within the Asparagaceae sensu lato. Stevens notes that most of its subfamilies are difficult to recognize, and that significantly different divisions have been used in the past, so that the use of a broadly defined family to refer to the entire clade is justified. Thus the relationships among subfamilies shown above, based on APWeb , is somewhat uncertain. + +Evolution +Several studies have attempted to date the evolution of the Asparagales, based on phylogenetic evidence. Earlier studies generally give younger dates than more recent studies, which have been preferred in the table below. + +A 2009 study suggests that the Asparagales have the highest diversification rate in the monocots, about the same as the order Poales, although in both orders the rate is little over half that of the eudicot order Lamiales, the clade with the highest rate. + +Comparison of family structures + + +The taxonomic diversity of the monocotyledons is described in detail by Kubitzki. Up-to-date information on the Asparagales can be found on the Angiosperm Phylogeny Website. + +The APG III system's family circumscriptions are being used as the basis of the Kew-hosted World Checklist of Selected Plant Families.

These are the families given under "including" in the list above. APG III does not allow bracketed families, requiring the use of the more comprehensive family; otherwise the circumscription of the Asparagales is unchanged. A separate paper accompanying the publication of the 2009 APG III system provided subfamilies to accommodate the families which were discontinued. The first APG system of 1998 contained some extra families, included in square brackets in the list above. + +Two older systems which use the order Asparagales are the Dahlgren system and the Kubitzki system.

Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Perhaps the most important food crop in the order is the corm of the taro plant, Colocasia esculenta. + +Description +The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. + +Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either floating or emerge above the water's surface. Vegetation may be totally submersed, have floating leaves, or protrude from the water. Collectively, they are commonly known as "water plantain". + +Taxonomy +The Alismatales contain about 165 genera in 13 families, with a cosmopolitan distribution. Phylogenetically, they are basal monocots, diverging early in evolution relative to the lilioid and commelinid monocot lineages. Together with the Acorales, the Alismatales are referred to informally as the alismatid monocots. + +Early systems +The Cronquist system (1981) places the Alismatales in subclass Alismatidae, class Liliopsida [= monocotyledons] and includes only three families as shown: + Alismataceae + Butomaceae + Limnocharitaceae +Cronquist's subclass Alismatidae conformed fairly closely to the order Alismatales as defined by APG, minus the Araceae. + +The Dahlgren system places the Alismatales in the superorder Alismatanae in the subclass Liliidae [= monocotyledons] in the class Magnoliopsida [= angiosperms] with the following families included: + Alismataceae + Aponogetonaceae + Butomaceae + Hydrocharitaceae + Limnocharitaceae + +In Tahktajan's classification (1997), the order Alismatales contains only the Alismataceae and Limnocharitaceae, making it equivalent to the Alismataceae as revised in APG-III. Other families included in the Alismatates as currently defined are here distributed among 10 additional orders, all of which are assigned, with the following exception, to the Subclass Alismatidae. Araceae in Tahktajan 1997 is assigned to the Arales and placed in the Subclass Aridae; Tofieldiaceae to the Melanthiales and placed in the Liliidae. + +Angiosperm Phylogeny Group +The Angiosperm Phylogeny Group system (APG) of 1998 and APG II (2003) assigned the Alismatales to the monocots, which may be thought of as an unranked clade containing the families listed below. The biggest departure from earlier systems (see below) is the inclusion of family Araceae. By its inclusion, the order has grown enormously in number of species. The family Araceae alone accounts for about a hundred genera, totaling over two thousand species. The rest of the families together contain only about five hundred species, many of which are in very small families. + +The APG III system (2009) differs only in that the Limnocharitaceae are combined with the Alismataceae; it was also suggested that the genus Maundia (of the Juncaginaceae) could be separated into a monogeneric family, the Maundiaceae, but the authors noted that more study was necessary before the Maundiaceae could be recognized. + + order Alismatales sensu APG III + family Alismataceae (including Limnocharitaceae) + family Aponogetonaceae + family Araceae + family Butomaceae + family Cymodoceaceae + family Hydrocharitaceae + family Juncaginaceae + family Posidoniaceae + family Potamogetonaceae + family Ruppiaceae + family Scheuchzeriaceae + family Tofieldiaceae + family Zosteraceae + +In APG IV (2016), it was decided that evidence was sufficient to elevate Maundia to family level as the monogeneric Maundiaceae. The authors considered including a number of the smaller orders within the Juncaginaceae, but an online survey of botanists and other users found little support for this "lumping" approach.

The families are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation and in particular, the Torriceliaceae may also be divided. + +Under this definition, well-known members include carrots, celery, parsley, and Hedera helix (English ivy). + +The order Apiales is placed within the asterid group of eudicots as circumscribed by the APG III system. Within the asterids, Apiales belongs to an unranked group called the campanulids, and within the campanulids, it belongs to a clade known in phylogenetic nomenclature as Apiidae. In 2010, a subclade of Apiidae named Dipsapiidae was defined to consist of the three orders: Apiales, Paracryphiales, and Dipsacales. + +Taxonomy +Under the Cronquist system, only the Apiaceae and Araliaceae were included here, and the restricted order was placed among the rosids rather than the asterids. The Pittosporaceae were placed within the Rosales, and many of the other forms within the family Cornaceae. Pennantia was in the family Icacinaceae. In the classification system of Dahlgren the families Apiaceae and Araliaceae were placed in the order Ariales, in the superorder Araliiflorae (also called Aralianae). + +The present understanding of the Apiales is fairly recent and is based upon comparison of DNA sequences by phylogenetic methods. The circumscriptions of some of the families have changed. In 2009, one of the subfamilies of Araliaceae was shown to be polyphyletic. + +Gynoecia +The largest and obviously closely related families of Apiales are Araliaceae, Myodocarpaceae and +Apiaceae, which resemble each other in the structure of their gynoecia. In this respect however, the Pittosporaceae is notably distinct from them. + +Typical syncarpous gynoecia exhibit four vertical zones, determined by the extent of fusion of the carpels. In most plants the synascidiate (i.e. "united bottle-shaped") and symplicate zones are fertile and bear the ovules. Each of the first three families possess mainly bi- or multilocular ovaries in a gynoecium with a long synascidiate, but very short symplicate zone, where the ovules are inserted at their transition, the so-called cross-zone (or "Querzone"). + +In gynoecia of the Pittosporaceae, the symplicate is much longer than the synascidiate zone, and the ovules are arranged along the first. Members of the latter family consequently have unilocular ovaries with a single cavity between adjacent carpels. + +References + + +Angiosperm orders +Taxa named by Takenoshin Nakai +Asterales () is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). + +The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the Lobelia deckenii, the giant lobelia, and Dendrosenecio, giant groundsels) and shrubs are also present. + +Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide inulin, a nutrient storage molecule used instead of starch; and unique stamen morphology. The stamens are usually found around the style, either aggregated densely or fused into a tube, probably an adaptation in association with the plunger (brush; or secondary) pollination that is common among the families of the order, wherein pollen is collected and stored on the length of the pistil. + +Taxonomy +The name and order Asterales is botanically venerable, dating back to at least 1926 in the Hutchinson system of plant taxonomy when it contained only five families, of which only two are retained in the APG III classification. Under the Cronquist system of taxonomic classification of flowering plants, Asteraceae was the only family in the group, but newer systems (such as APG II and APG III) have expanded it to 11. In the classification system of Rolf Dahlgren the Asterales were in the superorder Asteriflorae (also called Asteranae). + +The order Asterales currently includes 11 families, the largest of which are the Asteraceae, with about 25,000 species, and the Campanulaceae (bellflowers), with about 2,000 species. The remaining families count together for less than 1500 species. The two large families are cosmopolitan, with many of their species found in the Northern Hemisphere, and the smaller families are usually confined to Australia and the adjacent areas, or sometimes South America. + +Only the Asteraceae have composite flower heads; the other families do not, but share other characteristics such as storage of inulin that define the 11 families as more closely related to each other than to other plant families or orders such as the rosids. + +The phylogenetic tree according to APG III for the Campanulid clade is as below. + +Phylogeny +Although most extant species of Asteraceae are herbaceous, the examination of the basal members in the family suggests that the common ancestor of the family was an arborescent plant, a tree or shrub, perhaps adapted to dry conditions, radiating from South America. Less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub. + +Because all clades are represented in the Southern Hemisphere but many not in the Northern Hemisphere, it is natural to conjecture that there is a common southern origin to them. Asterales are angiosperms, flowering plants that appeared about 140 million years ago. The Asterales order probably originated in the Cretaceous (145 – 66 Mya) on the supercontinent Gondwana which broke up from 184 – 80 Mya, forming the area that is now Australia, South America, Africa, India and Antarctica. + +Asterales contain about 14% of eudicot diversity. From an analysis of relationships and diversities within the Asterales and with their superorders, estimates of the age of the beginning of the Asterales have been made, which range from 116 Mya to 82Mya. However few fossils have been found, of the Menyanthaceae-Asteraceae clade in the Oligocene, about 29 Mya. + +Fossil evidence of the Asterales is rare and belongs to rather recent epochs, so the precise estimation of the order's age is quite difficult. An Oligocene (34 – 23 Mya) pollen is known for Asteraceae and Goodeniaceae, and seeds from Oligocene and Miocene (23 – 5.3 Mya) are known for Menyanthaceae and Campanulaceae respectively. + +Biogeography +The core Asterales are Stylidiaceae (six genera), APA clade (Alseuosmiaceae, Phellinaceae and Argophyllaceae, together seven genera), MGCA clade (Menyanthaceae, Goodeniaceae, Calyceraceae, in total twenty genera), and Asteraceae (about sixteen hundred genera). Other Asterales are Rousseaceae (four genera), Campanulaceae (eighty-four genera) and Pentaphragmataceae (one genus). + +All Asterales families are represented in the Southern Hemisphere; however, Asteraceae and Campanulaceae are cosmopolitan and Menyanthaceae nearly so. + +Uses +The Asterales, by dint of being a super-set of the family Asteraceae, include some species grown for food, including the sunflower (Helianthus annuus), lettuce (Lactuca sativa) and chicory (Cichorium). Many are also used as spices and traditional medicines. + +Asterales are common plants and have many known uses. For example, pyrethrum (derived from Old World members of the genus Chrysanthemum) is a natural insecticide with minimal environmental impact. Wormwood, derived from a genus that includes the sagebrush, is used as a source of flavoring for absinthe, a bitter classical liquor of European origin. + +References + +Further reading + W. S.

Sinauer Associates, Sunderland, Massachusetts. . + +External links + + +Angiosperm orders +An asteroid is a minor planet—an object that is neither a true planet nor a comet—that orbits within the inner Solar System. They are rocky, metallic or icy bodies with no atmosphere. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter. + +Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to complete a full circuit of the Sun. + +Asteroids have been historically observed from Earth; the Galileo spacecraft provided the first close observation of an asteroid. Several dedicated missions to asteroids were subsequently launched by NASA and JAXA, with plans for other missions in progress. NASA's NEAR Shoemaker studied Eros, and Dawn observed Vesta and Ceres. JAXA's missions Hayabusa and Hayabusa2 studied and returned samples of Itokawa and Ryugu, respectively. OSIRIS-REx studied Bennu, collecting a sample in 2020 which was delivered back to Earth in 2023. NASA's Lucy, launched in 2021, will study ten different asteroids, two from the main belt and eight Jupiter trojans. Psyche, launched in October 2023, will study a metallic asteroid of the same name. + +Near-Earth asteroids can threaten all life on the planet; an asteroid impact event resulted in the Cretaceous–Paleogene extinction. Different asteroid deflection strategies have been proposed; the Double Asteroid Redirection Test spacecraft, or DART, was launched in 2021 and intentionally impacted Dimorphos in September 2022, successfully altering its orbit by crashing into it. + +History of observations +Only one asteroid, 4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye. When favorably positioned, 4 Vesta can be seen in dark skies. Rarely, small asteroids passing close to Earth may be visible to the naked eye for a short amount of time. , the Minor Planet Center had data on 1,199,224 minor planets in the inner and outer Solar System, of which about 614,690 had enough information to be given numbered designations. + +Discovery of Ceres +In 1772, German astronomer Johann Elert Bode, citing Johann Daniel Titius, published a numerical procession known as the Titius–Bode law (now discredited). Except for an unexplained gap between Mars and Jupiter, Bode's formula seemed to predict the orbits of the known planets. He wrote the following explanation for the existence of a "missing planet": + +This latter point seems in particular to follow from the astonishing relation which the known six planets observe in their distances from the Sun. Let the distance from the Sun to Saturn be taken as 100, then Mercury is separated by 4 such parts from the Sun. Venus is 4 + 3 = 7. The Earth 4 + 6 = 10. Mars 4 + 12 = 16. Now comes a gap in this so orderly progression. After Mars there follows a space of 4 + 24 = 28 parts, in which no planet has yet been seen. Can one believe that the Founder of the universe had left this space empty? Certainly not. From here we come to the distance of Jupiter by 4 + 48 = 52 parts, and finally to that of Saturn by 4 + 96 = 100 parts. + +Bode's formula predicted another planet would be found with an orbital radius near 2.8 astronomical units (AU), or 420 million km, from the Sun. The Titius–Bode law got a boost with William Herschel's discovery of Uranus near the predicted distance for a planet beyond Saturn. In 1800, a group headed by Franz Xaver von Zach, editor of the German astronomical journal Monatliche Correspondenz (Monthly Correspondence), sent requests to 24 experienced astronomers (whom he dubbed the "celestial police"), asking that they combine their efforts and begin a methodical search for the expected planet. Although they did not discover Ceres, they later found the asteroids 2 Pallas, 3 Juno and 4 Vesta. + +One of the astronomers selected for the search was Giuseppe Piazzi, a Catholic priest at the Academy of Palermo, Sicily. Before receiving his invitation to join the group, Piazzi discovered Ceres on 1 January 1801. He was searching for "the 87th [star] of the Catalogue of the Zodiacal stars of Mr la Caille", but found that "it was preceded by another". Instead of a star, Piazzi had found a moving star-like object, which he first thought was a comet: + +The light was a little faint, and of the colour of Jupiter, but similar to many others which generally are reckoned of the eighth magnitude. Therefore I had no doubt of its being any other than a fixed star. [...] The evening of the third, my suspicion was converted into certainty, being assured it was not a fixed star. Nevertheless before I made it known, I waited till the evening of the fourth, when I had the satisfaction to see it had moved at the same rate as on the preceding days. + +Piazzi observed Ceres a total of 24 times, the final time on 11 February 1801, when illness interrupted his work. He announced his discovery on 24 January 1801 in letters to only two fellow astronomers, his compatriot Barnaba Oriani of Milan and Bode in Berlin. He reported it as a comet but "since its movement is so slow and rather uniform, it has occurred to me several times that it might be something better than a comet". In April, Piazzi sent his complete observations to Oriani, Bode, and French astronomer Jérôme Lalande. The information was published in the September 1801 issue of the Monatliche Correspondenz. + +By this time, the apparent position of Ceres had changed (mostly due to Earth's motion around the Sun), and was too close to the Sun's glare for other astronomers to confirm Piazzi's observations. Toward the end of the year, Ceres should have been visible again, but after such a long time it was difficult to predict its exact position. To recover Ceres, mathematician Carl Friedrich Gauss, then 24 years old, developed an efficient method of orbit determination. In a few weeks, he predicted the path of Ceres and sent his results to von Zach. On 31 December 1801, von Zach and fellow celestial policeman Heinrich W. M. Olbers found Ceres near the predicted position and thus recovered it. At 2.8 AU from the Sun, Ceres appeared to fit the Titius–Bode law almost perfectly; however, Neptune, once discovered in 1846, was 8 AU closer than predicted, leading most astronomers to conclude that the law was a coincidence. Piazzi named the newly discovered object Ceres Ferdinandea, "in honor of the patron goddess of Sicily and of King Ferdinand of Bourbon". + +Further search + +Three other asteroids (2 Pallas, 3 Juno, and 4 Vesta) were discovered by von Zach's group over the next few years, with Vesta found in 1807. No new asteroids were discovered until 1845. Amateur astronomer Karl Ludwig Hencke started his searches of new asteroids in 1830, and fifteen years later, while looking for Vesta, he found the asteroid later named 5 Astraea. It was the first new asteroid discovery in 38 years. Carl Friedrich Gauss was given the honor of naming the asteroid. After this, other astronomers joined; 15 asteroids were found by the end of 1851. In 1868, when James Craig Watson discovered the 100th asteroid, the French Academy of Sciences engraved the faces of Karl Theodor Robert Luther, John Russell Hind, and Hermann Goldschmidt, the three most successful asteroid-hunters at that time, on a commemorative medallion marking the event. + +In 1891, Max Wolf pioneered the use of astrophotography to detect asteroids, which appeared as short streaks on long-exposure photographic plates. This dramatically increased the rate of detection compared with earlier visual methods: Wolf alone discovered 248 asteroids, beginning with 323 Brucia, whereas only slightly more than 300 had been discovered up to that point. It was known that there were many more, but most astronomers did not bother with them, some calling them "vermin of the skies", a phrase variously attributed to Eduard Suess and Edmund Weiss. Even a century later, only a few thousand asteroids were identified, numbered and named. + +19th and 20th centuries + +In the past, asteroids were discovered by a four-step process. First, a region of the sky was photographed by a wide-field telescope, or astrograph. Pairs of photographs were taken, typically one hour apart. Multiple pairs could be taken over a series of days. Second, the two films or plates of the same region were viewed under a stereoscope. A body in orbit around the Sun would move slightly between the pair of films. Under the stereoscope, the image of the body would seem to float slightly above the background of stars. Third, once a moving body was identified, its location would be measured precisely using a digitizing microscope. The location would be measured relative to known star locations. + +These first three steps do not constitute asteroid discovery: the observer has only found an apparition, which gets a provisional designation, made up of the year of discovery, a letter representing the half-month of discovery, and finally a letter and a number indicating the discovery's sequential number (example: ). The last step is sending the locations and time of observations to the Minor Planet Center, where computer programs determine whether an apparition ties together earlier apparitions into a single orbit. If so, the object receives a catalogue number and the observer of the first apparition with a calculated orbit is declared the discoverer, and granted the honor of naming the object subject to the approval of the International Astronomical Union. + +Naming + +By 1851, the Royal Astronomical Society decided that asteroids were being discovered at such a rapid rate that a different system was needed to categorize or name asteroids. In 1852, when de Gasparis discovered the twentieth asteroid, Benjamin Valz gave it a name and a number designating its rank among asteroid discoveries, 20 Massalia. Sometimes asteroids were discovered and not seen again. So, starting in 1892, new asteroids were listed by the year and a capital letter indicating the order in which the asteroid's orbit was calculated and registered within that specific year. For example, the first two asteroids discovered in 1892 were labeled 1892A and 1892B. However, there were not enough letters in the alphabet for all of the asteroids discovered in 1893, so 1893Z was followed by 1893AA. A number of variations of these methods were tried, including designations that included year plus a Greek letter in 1914. A simple chronological numbering system was established in 1925. + +Currently all newly discovered asteroids receive a provisional designation (such as ) consisting of the year of discovery and an alphanumeric code indicating the half-month of discovery and the sequence within that half-month. Once an asteroid's orbit has been confirmed, it is given a number, and later may also be given a name (e.g. ). The formal naming convention uses parentheses around the number—e.g. (433) Eros—but dropping the parentheses is quite common. Informally, it is also common to drop the number altogether, or to drop it after the first mention when a name is repeated in running text. In addition, names can be proposed by the asteroid's discoverer, within guidelines established by the International Astronomical Union. + +Symbols + +The first asteroids to be discovered were assigned iconic symbols like the ones traditionally used to designate the planets. By 1855 there were two dozen asteroid symbols, which often occurred in multiple variants. + +In 1851, after the fifteenth asteroid, Eunomia, had been discovered, Johann Franz Encke made a major change in the upcoming 1854 edition of the Berliner Astronomisches Jahrbuch (BAJ, Berlin Astronomical Yearbook). He introduced a disk (circle), a traditional symbol for a star, as the generic symbol for an asteroid. The circle was then numbered in order of discovery to indicate a specific asteroid. The numbered-circle convention was quickly adopted by astronomers, and the next asteroid to be discovered (16 Psyche, in 1852) was the first to be designated in that way at the time of its discovery. However, Psyche was given an iconic symbol as well, as were a few other asteroids discovered over the next few years. 20 Massalia was the first asteroid that was not assigned an iconic symbol, and no iconic symbols were created after the 1855 discovery of 37 Fides. + +Terminology + +The first discovered asteroid, Ceres, was originally considered a new planet. It was followed by the discovery of other similar bodies, which with the equipment of the time appeared to be points of light like stars, showing little or no planetary disc, though readily distinguishable from stars due to their apparent motions. This prompted the astronomer Sir William Herschel to propose the term asteroid, coined in Greek as ἀστεροειδής, or asteroeidēs, meaning 'star-like, star-shaped', and derived from the Ancient Greek astēr 'star, planet'. In the early second half of the 19th century, the terms asteroid and planet (not always qualified as "minor") were still used interchangeably. + +Traditionally, small bodies orbiting the Sun were classified as comets, asteroids, or meteoroids, with anything smaller than one meter across being called a meteoroid. The term asteroid never had a formal definition, with the broader term small Solar System bodies being preferred by the International Astronomical Union (IAU). As no IAU definition exists, asteroid can be defined as "an irregularly shaped rocky body orbiting the Sun that does not qualify as a planet or a dwarf planet under the IAU definitions of those terms". + +When found, asteroids were seen as a class of objects distinct from comets, and there was no unified term for the two until small Solar System body was coined in 2006. The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near-surface ices by solar radiation. A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity. Conversely, some (perhaps all) comets are eventually depleted of their surface volatile ices and become asteroid-like. A further distinction is that comets typically have more eccentric orbits than most asteroids; "asteroids" with notably eccentric orbits are probably dormant or extinct comets. + +For almost two centuries, from the discovery of Ceres in 1801 until the discovery of the first centaur, 2060 Chiron in 1977, all known asteroids spent most of their time at or within the orbit of Jupiter, though a few such as 944 Hidalgo ventured far beyond Jupiter for part of their orbit. When astronomers started finding more small bodies that permanently resided further out than Jupiter, now called centaurs, they numbered them among the traditional asteroids. There was debate over whether these objects should be considered asteroids or given a new classification. Then, when the first trans-Neptunian object (other than Pluto), 15760 Albion, was discovered in 1992, and especially when large numbers of similar objects started turning up, new terms were invented to sidestep the issue: Kuiper-belt object, trans-Neptunian object, scattered-disc object, and so on. They inhabit the cold outer reaches of the Solar System where ices remain solid and comet-like bodies are not expected to exhibit much cometary activity; if centaurs or trans-Neptunian objects were to venture close to the Sun, their volatile ices would sublimate, and traditional approaches would classify them as comets and not asteroids. + +The innermost of these are the Kuiper-belt objects, called "objects" partly to avoid the need to classify them as asteroids or comets. They are thought to be predominantly comet-like in composition, though some may be more akin to asteroids. Furthermore, most do not have the highly eccentric orbits associated with comets, and the ones so far discovered are larger than traditional comet nuclei. (The much more distant Oort cloud is hypothesized to be the main reservoir of dormant comets.) Other recent observations, such as the analysis of the cometary dust collected by the Stardust probe, are increasingly blurring the distinction between comets and asteroids, suggesting "a continuum between asteroids and comets" rather than a sharp dividing line. + +The minor planets beyond Jupiter's orbit are sometimes also called "asteroids", especially in popular presentations. However, it is becoming increasingly common for the term asteroid to be restricted to minor planets of the inner Solar System. Therefore, this article will restrict itself for the most part to the classical asteroids: objects of the asteroid belt, Jupiter trojans, and near-Earth objects. + +When the IAU introduced the class small Solar System bodies in 2006 to include most objects previously classified as minor planets and comets, they created the class of dwarf planets for the largest minor planets—those that have enough mass to have become ellipsoidal under their own gravity. According to the IAU, "the term 'minor planet' may still be used, but generally, the term 'Small Solar System Body' will be preferred." Currently only the largest object in the asteroid belt, Ceres, at about across, has been placed in the dwarf planet category. + +Formation + +Many asteroids are the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. It is thought that planetesimals in the asteroid belt evolved much like the rest of objects in the solar nebula until Jupiter neared its current mass, at which point excitation from orbital resonances with Jupiter ejected over 99% of planetesimals in the belt. Simulations and a discontinuity in spin rate and spectral properties suggest that asteroids larger than approximately in diameter accreted during that early era, whereas smaller bodies are fragments from collisions between asteroids during or after the Jovian disruption. Ceres and Vesta grew large enough to melt and differentiate, with heavy metallic elements sinking to the core, leaving rocky minerals in the crust. + +In the Nice model, many Kuiper-belt objects are captured in the outer asteroid belt, at distances greater than 2.6 AU. Most were later ejected by Jupiter, but those that remained may be the D-type asteroids, and possibly include Ceres. + +Distribution within the Solar System + +Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System. Their orbits are perturbed by the gravity of other bodies in the Solar System and by the Yarkovsky effect. Significant populations include: + +Asteroid belt + +The majority of known asteroids orbit within the asteroid belt between the orbits of Mars and Jupiter, generally in relatively low-eccentricity (i.e. not very elongated) orbits. This belt is estimated to contain between 1.1 and 1.9 million asteroids larger than in diameter, and millions of smaller ones. These asteroids may be remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the Solar System was prevented by large gravitational perturbations by Jupiter. + +Contrary to popular imagery, the asteroid belt is mostly empty. The asteroids are spread over such a large volume that reaching an asteroid without aiming carefully would be improbable. Nonetheless, hundreds of thousands of asteroids are currently known, and the total number ranges in the millions or more, depending on the lower size cutoff. Over 200 asteroids are known to be larger than 100 km, and a survey in the infrared wavelengths has shown that the asteroid belt has between 700,000 and 1.7 million asteroids with a diameter of 1 km or more. The absolute magnitudes of most of the known asteroids are between 11 and 19, with the median at about 16. + +The total mass of the asteroid belt is estimated to be kg, which is just 3% of the mass of the Moon; the mass of the Kuiper Belt and Scattered Disk is over 100 times as large. The four largest objects, Ceres, Vesta, Pallas, and Hygiea, account for maybe 62% of the belt's total mass, with 39% accounted for by Ceres alone. + +Trojans + +Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two Lagrangian points of stability, and , which lie 60° ahead of and behind the larger body. + +In the Solar System, most known trojans share the orbit of Jupiter. They are divided into the Greek camp at (ahead of Jupiter) and the Trojan camp at (trailing Jupiter). More than a million Jupiter trojans larger than one kilometer are thought to exist, of which more than 7,000 are currently catalogued. In other planetary orbits only nine Mars trojans, 28 Neptune trojans, two Uranus trojans, and two Earth trojans, have been found to date. A temporary Venus trojan is also known. Numerical orbital dynamics stability simulations indicate that Saturn and Uranus probably do not have any primordial trojans. + +Near-Earth asteroids + +Near-Earth asteroids, or NEAs, are asteroids that have orbits that pass close to that of Earth. Asteroids that actually cross Earth's orbital path are known as Earth-crossers. , a total of 28,772 near-Earth asteroids were known; 878 have a diameter of one kilometer or larger. + +A small number of NEAs are extinct comets that have lost their volatile surface materials, although having a faint or intermittent comet-like tail does not necessarily result in a classification as a near-Earth comet, making the boundaries somewhat fuzzy. The rest of the near-Earth asteroids are driven out of the asteroid belt by gravitational interactions with Jupiter. + +Many asteroids have natural satellites (minor-planet moons). , there were 85 NEAs known to have at least one moon, including three known to have two moons. The asteroid 3122 Florence, one of the largest potentially hazardous asteroids with a diameter of , has two moons measuring across, which were discovered by radar imaging during the asteroid's 2017 approach to Earth. + +Near-Earth asteroids are divided into groups based on their semi-major axis (a), perihelion distance (q), and aphelion distance (Q): + The Atiras or Apoheles have orbits strictly inside Earth's orbit: an Atira asteroid's aphelion distance (Q) is smaller than Earth's perihelion distance (0.983 AU). That is, , which implies that the asteroid's semi-major axis is also less than 0.983 AU. + The Atens have a semi-major axis of less than 1 AU and cross Earth's orbit. Mathematically, and . (0.983 AU is Earth's perihelion distance.) + The Apollos have a semi-major axis of more than 1 AU and cross Earth's orbit. Mathematically, and . (1.017 AU is Earth's aphelion distance.) + The Amors have orbits strictly outside Earth's orbit: an Amor asteroid's perihelion distance (q) is greater than Earth's aphelion distance (1.017 AU). Amor asteroids are also near-earth objects so . In summary, . (This implies that the asteroid's semi-major axis (a) is also larger than 1.017 AU.) Some Amor asteroid orbits cross the orbit of Mars. + +Martian moons + +It is unclear whether Martian moons Phobos and Deimos are captured asteroids or were formed due to impact event on Mars. Phobos and Deimos both have much in common with carbonaceous C-type asteroids, with spectra, albedo, and density very similar to those of C- or D-type asteroids. Based on their similarity, one hypothesis is that both moons may be captured main-belt asteroids. Both moons have very circular orbits which lie almost exactly in Mars's equatorial plane, and hence a capture origin requires a mechanism for circularizing the initially highly eccentric orbit, and adjusting its inclination into the equatorial plane, most probably by a combination of atmospheric drag and tidal forces, although it is not clear whether sufficient time was available for this to occur for Deimos. Capture also requires dissipation of energy. The current Martian atmosphere is too thin to capture a Phobos-sized object by atmospheric braking. Geoffrey A. Landis has pointed out that the capture could have occurred if the original body was a binary asteroid that separated under tidal forces. + +Phobos could be a second-generation Solar System object that coalesced in orbit after Mars formed, rather than forming concurrently out of the same birth cloud as Mars. + +Another hypothesis is that Mars was once surrounded by many Phobos- and Deimos-sized bodies, perhaps ejected into orbit around it by a collision with a large planetesimal. The high porosity of the interior of Phobos (based on the density of 1.88 g/cm3, voids are estimated to comprise 25 to 35 percent of Phobos's volume) is inconsistent with an asteroidal origin. Observations of Phobos in the thermal infrared suggest a composition containing mainly phyllosilicates, which are well known from the surface of Mars. The spectra are distinct from those of all classes of chondrite meteorites, again pointing away from an asteroidal origin. Both sets of findings support an origin of Phobos from material ejected by an impact on Mars that reaccreted in Martian orbit, similar to the prevailing theory for the origin of Earth's moon. + +Characteristics + +Size distribution + +Asteroids vary greatly in size, from almost for the largest down to rocks just 1 meter across, below which an object is classified as a meteoroid. The three largest are very much like miniature planets: they are roughly spherical, have at least partly differentiated interiors, and are thought to be surviving protoplanets. The vast majority, however, are much smaller and are irregularly shaped; they are thought to be either battered planetesimals or fragments of larger bodies. + +The dwarf planet Ceres is by far the largest asteroid, with a diameter of . The next largest are 4 Vesta and 2 Pallas, both with diameters of just over . Vesta is the brightest of the four main-belt asteroids that can, on occasion, be visible to the naked eye. On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis. + +The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be , ≈ 3.25% of the mass of the Moon. Of this, Ceres comprises , about 40% of the total. Adding in the next three most massive objects, Vesta (11%), Pallas (8.5%), and Hygiea (3–4%), brings this figure up to a bit over 60%, whereas the next seven most-massive asteroids bring the total up to 70%. The number of asteroids increases rapidly as their individual masses decrease. + +The number of asteroids decreases markedly with increasing size. Although the size distribution generally follows a power law, there are 'bumps' at about and , where more asteroids than expected from such a curve are found. Most asteroids larger than approximately 120 km in diameter are primordial (surviving from the accretion epoch), whereas most smaller asteroids are products of fragmentation of primordial asteroids. The primordial population of the main belt was probably 200 times what it is today. + +Largest asteroids + +Three largest objects in the asteroid belt, Ceres, Vesta, and Pallas, are intact protoplanets that share many characteristics common to planets, and are atypical compared to the majority of irregularly shaped asteroids. The fourth-largest asteroid, Hygiea, appears nearly spherical although it may have an undifferentiated interior, like the majority of asteroids. The four largest asteroids constitute half the mass of the asteroid belt. + +Ceres is the only asteroid that appears to have a plastic shape under its own gravity and hence the only one that is a dwarf planet. It has a much higher absolute magnitude than the other asteroids, of around 3.32, and may possess a surface layer of ice. Like the planets, Ceres is differentiated: it has a crust, a mantle and a core. No meteorites from Ceres have been found on Earth. + +Vesta, too, has a differentiated interior, though it formed inside the Solar System's frost line, and so is devoid of water; its composition is mainly of basaltic rock with minerals such as olivine. Aside from the large crater at its southern pole, Rheasilvia, Vesta also has an ellipsoidal shape. Vesta is the parent body of the Vestian family and other V-type asteroids, and is the source of the HED meteorites, which constitute 5% of all meteorites on Earth. + +Pallas is unusual in that, like Uranus, it rotates on its side, with its axis of rotation tilted at high angles to its orbital plane. Its composition is similar to that of Ceres: high in carbon and silicon, and perhaps partially differentiated. Pallas is the parent body of the Palladian family of asteroids. + +Hygiea is the largest carbonaceous asteroid and, unlike the other largest asteroids, lies relatively close to the plane of the ecliptic. It is the largest member and presumed parent body of the Hygiean family of asteroids. Because there is no sufficiently large crater on the surface to be the source of that family, as there is on Vesta, it is thought that Hygiea may have been completely disrupted in the collision that formed the Hygiean family and recoalesced after losing a bit less than 2% of its mass. Observations taken with the Very Large Telescope's SPHERE imager in 2017 and 2018, revealed that Hygiea has a nearly spherical shape, which is consistent both with it being in hydrostatic equilibrium, or formerly being in hydrostatic equilibrium, or with being disrupted and recoalescing. + +Internal differentiation of large asteroids is possibly related to their lack of natural satellites, as satellites of main belt asteroids are mostly believed to form from collisional disruption, creating a rubble pile structure. + +Rotation + +Measurements of the rotation rates of large asteroids in the asteroid belt show that there is an upper limit. Very few asteroids with a diameter larger than 100 meters have a rotation period less than 2.2 hours. For asteroids rotating faster than approximately this rate, the inertial force at the surface is greater than the gravitational force, so any loose surface material would be flung out. However, a solid object should be able to rotate much more rapidly. This suggests that most asteroids with a diameter over 100 meters are rubble piles formed through the accumulation of debris after collisions between asteroids. + +Color +Asteroids become darker and redder with age due to space weathering. However evidence suggests most of the color change occurs rapidly, in the first hundred thousand years, limiting the usefulness of spectral measurement for determining the age of asteroids. + +Surface features + +Except for the "big four" (Ceres, Pallas, Vesta, and Hygiea), asteroids are likely to be broadly similar in appearance, if irregular in shape. 253 Mathilde is a rubble pile saturated with craters with diameters the size of the asteroid's radius. Earth-based observations of 511 Davida, one of the largest asteroids after the big four, reveal a similarly angular profile, suggesting it is also saturated with radius-size craters. Medium-sized asteroids such as Mathilde and 243 Ida, that have been observed up close, also reveal a deep regolith covering the surface. Of the big four, Pallas and Hygiea are practically unknown. Vesta has compression fractures encircling a radius-size crater at its south pole but is otherwise a spheroid. + +Dawn spacecraft revealed that Ceres has a heavily cratered surface, but with fewer large craters than expected. Models based on the formation of the current asteroid belt had suggested Ceres should possess 10 to 15 craters larger than in diameter. The largest confirmed crater on Ceres, Kerwan Basin, is across. The most likely reason for this is viscous relaxation of the crust slowly flattening out larger impacts. + +Composition +Asteroids are classified by their characteristic emission spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous (carbon-rich), metallic, and silicaceous (stony) compositions, respectively. The physical composition of asteroids is varied and in most cases poorly understood. Ceres appears to be composed of a rocky core covered by an icy mantle, where Vesta is thought to have a nickel-iron core, olivine mantle, and basaltic crust. Thought to be the largest undifferentiated asteroid, 10 Hygiea seems to have a uniformly primitive composition of carbonaceous chondrite, but it may actually be a differentiated asteroid that was globally disrupted by an impact and then reassembled. Other asteroids appear to be the remnant cores or mantles of proto-planets, high in rock and metal. Most small asteroids are believed to be piles of rubble held together loosely by gravity, although the largest are probably solid. Some asteroids have moons or are co-orbiting binaries: rubble piles, moons, binaries, and scattered asteroid families are thought to be the results of collisions that disrupted a parent asteroid, or possibly a planet. + +In the main asteroid belt, there appear to be two primary populations of asteroid: a dark, volatile-rich population, consisting of the C-type and P-type asteroids, with albedos less than 0.10 and densities under , and a dense, volatile-poor population, consisting of the S-type and M-type asteroids, with albedos over 0.15 and densities greater than 2.7. Within these populations, larger asteroids are denser, presumably due to compression. There appears to be minimal macro-porosity (interstitial vacuum) in the score of asteroids with masses greater than . + +Composition is calculated from three primary sources: albedo, surface spectrum, and density. The last can only be determined accurately by observing the orbits of moons the asteroid might have. So far, every asteroid with moons has turned out to be a rubble pile, a loose conglomeration of rock and metal that may be half empty space by volume. The investigated asteroids are as large as 280 km in diameter, and include 121 Hermione (268×186×183 km), and 87 Sylvia (384×262×232 km). Few asteroids are larger than 87 Sylvia, none of them have moons. The fact that such large asteroids as Sylvia may be rubble piles, presumably due to disruptive impacts, has important consequences for the formation of the Solar System: computer simulations of collisions involving solid bodies show them destroying each other as often as merging, but colliding rubble piles are more likely to merge. This means that the cores of the planets could have formed relatively quickly. + +Water + +Scientists hypothesize that some of the first water brought to Earth was delivered by asteroid impacts after the collision that produced the Moon. In 2009, the presence of water ice was confirmed on the surface of 24 Themis using NASA's Infrared Telescope Facility. The surface of the asteroid appears completely covered in ice. As this ice layer is sublimating, it may be getting replenished by a reservoir of ice under the surface. Organic compounds were also detected on the surface. The presence of ice on 24 Themis makes the initial theory plausible. + +In October 2013, water was detected on an extrasolar body for the first time, on an asteroid orbiting the white dwarf GD 61. On 22 January 2014, European Space Agency (ESA) scientists reported the detection, for the first definitive time, of water vapor on Ceres, the largest object in the asteroid belt. The detection was made by using the far-infrared abilities of the Herschel Space Observatory. The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids." + +Findings have shown that solar winds can react with the oxygen in the upper layer of the asteroids and create water. It has been estimated that "every cubic metre of irradiated rock could contain up to 20 litres"; study was conducted using an atom probe tomography, numbers are given for the Itokawa S-type asteroid. + +Acfer 049, a meteorite discovered in Algeria in 1990, was shown in 2019 to have an ultraporous lithology (UPL): porous texture that could be formed by removal of ice that filled these pores, this suggests that UPL "represent fossils of primordial ice". + +Organic compounds + +Asteroids contain traces of amino acids and other organic compounds, and some speculate that asteroid impacts may have seeded the early Earth with the chemicals necessary to initiate life, or may have even brought life itself to Earth (an event called "panspermia"). In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting DNA and RNA components (adenine, guanine and related organic molecules) may have been formed on asteroids and comets in outer space. + +In November 2019, scientists reported detecting, for the first time, sugar molecules, including ribose, in meteorites, suggesting that chemical processes on asteroids can produce some fundamentally essential bio-ingredients important to life, and supporting the notion of an RNA world prior to a DNA-based origin of life on Earth, and possibly, as well, the notion of panspermia. + +Classification +Asteroids are commonly categorized according to two criteria: the characteristics of their orbits, and features of their reflectance spectrum. + +Orbital classification + +Many asteroids have been placed in groups and families based on their orbital characteristics. Apart from the broadest divisions, it is customary to name a group of asteroids after the first member of that group to be discovered. Groups are relatively loose dynamical associations, whereas families are tighter and result from the catastrophic break-up of a large parent asteroid sometime in the past. Families are more common and easier to identify within the main asteroid belt, but several small families have been reported among the Jupiter trojans. Main belt families were first recognized by Kiyotsugu Hirayama in 1918 and are often called Hirayama families in his honor. + +About 30–35% of the bodies in the asteroid belt belong to dynamical families, each thought to have a common origin in a past collision between asteroids. A family has also been associated with the plutoid dwarf planet . + +Some asteroids have unusual horseshoe orbits that are co-orbital with Earth or another planet. Examples are 3753 Cruithne and . The first instance of this type of orbital arrangement was discovered between Saturn's moons Epimetheus and Janus. Sometimes these horseshoe objects temporarily become quasi-satellites for a few decades or a few hundred years, before returning to their earlier status. Both Earth and Venus are known to have quasi-satellites. + +Such objects, if associated with Earth or Venus or even hypothetically Mercury, are a special class of Aten asteroids. However, such objects could be associated with the outer planets as well. + +Spectral classification + +In 1975, an asteroid taxonomic system based on color, albedo, and spectral shape was developed by Chapman, Morrison, and Zellner. These properties are thought to correspond to the composition of the asteroid's surface material. The original classification system had three categories: C-types for dark carbonaceous objects (75% of known asteroids), S-types for stony (silicaceous) objects (17% of known asteroids) and U for those that did not fit into either C or S. This classification has since been expanded to include many other asteroid types. The number of types continues to grow as more asteroids are studied. + +The two most widely used taxonomies now used are the Tholen classification and SMASS classification. The former was proposed in 1984 by David J. Tholen, and was based on data collected from an eight-color asteroid survey performed in the 1980s. This resulted in 14 asteroid categories. In 2002, the Small Main-Belt Asteroid Spectroscopic Survey resulted in a modified version of the Tholen taxonomy with 24 different types. Both systems have three broad categories of C, S, and X asteroids, where X consists of mostly metallic asteroids, such as the M-type. There are also several smaller classes. + +The proportion of known asteroids falling into the various spectral types does not necessarily reflect the proportion of all asteroids that are of that type; some types are easier to detect than others, biasing the totals. + +Problems +Originally, spectral designations were based on inferences of an asteroid's composition. However, the correspondence between spectral class and composition is not always very good, and a variety of classifications are in use. This has led to significant confusion. Although asteroids of different spectral classifications are likely to be composed of different materials, there are no assurances that asteroids within the same taxonomic class are composed of the same (or similar) materials. + +Active asteroids + +Active asteroids are objects that have asteroid-like orbits but show comet-like visual characteristics. That is, they show comae, tails, or other visual evidence of mass-loss (like a comet), but their orbit remains within Jupiter's orbit (like an asteroid). These bodies were originally designated main-belt comets (MBCs) in 2006 by astronomers David Jewitt and Henry Hsieh, but this name implies they are necessarily icy in composition like a comet and that they only exist within the main-belt, whereas the growing population of active asteroids shows that this is not always the case. + +The first active asteroid discovered is 7968 Elst–Pizarro. It was discovered (as an asteroid) in 1979 but then was found to have a tail by Eric Elst and Guido Pizarro in 1996 and given the cometary designation 133P/Elst-Pizarro. Another notable object is 311P/PanSTARRS: observations made by the Hubble Space Telescope revealed that it had six comet-like tails. The tails are suspected to be streams of material ejected by the asteroid as a result of a rubble pile asteroid spinning fast enough to remove material from it. + +By smashing into the asteroid Dimorphos, NASA's Double Asteroid Redirection Test spacecraft made it an active asteroid. Scientists had proposed that some active asteroids are the result of impact events, but no one had ever observed the activation of an asteroid. The DART mission activated Dimorphos under precisely known and carefully observed impact conditions, enabling the detailed study of the formation of an active asteroid for the first time. Observations show that Dimorphos lost approximately 1 million kilograms after the collision. Impact produced a dust plume that temporarily brightened the Didymos system and developed a -long dust tail that persisted for several months. + +Observation and exploration +Until the age of space travel, objects in the asteroid belt could only be observed with large telescopes, their shapes and terrain remaining a mystery. The best modern ground-based telescopes and the Earth-orbiting Hubble Space Telescope can only resolve a small amount of detail on the surfaces of the largest asteroids. Limited information about the shapes and compositions of asteroids can be inferred from their light curves (variation in brightness during rotation) and their spectral properties. Sizes can be estimated by timing the lengths of star occultations (when an asteroid passes directly in front of a star). Radar imaging can yield good information about asteroid shapes and orbital and rotational parameters, especially for near-Earth asteroids. Spacecraft flybys can provide much more data than any ground or space-based observations; sample-return missions gives insights about regolith composition. + +Ground-based observations + +As asteroids are rather small and faint objects, the data that can be obtained from ground-based observations (GBO) are limited. By means of ground-based optical telescopes the visual magnitude can be obtained; when converted into the absolute magnitude it gives a rough estimate of the asteroid's size. Light-curve measurements can also be made by GBO; when collected over a long period of time it allows an estimate of the rotational period, the pole orientation (sometimes), and a rough estimate of the asteroid's shape. Spectral data (both visible-light and near-infrared spectroscopy) gives information about the object's composition, used to classify the observed asteroids. Such observations are limited as they provide information about only the thin layer on the surface (up to several micrometers). As planetologist Patrick Michel writes: + +Mid- to thermal-infrared observations, along with polarimetry measurements, are probably the only data that give some indication of actual physical properties. Measuring the heat flux of an asteroid at a single wavelength gives an estimate of the dimensions of the object; these measurements have lower uncertainty than measurements of the reflected sunlight in the visible-light spectral region. If the two measurements can be combined, both the effective diameter and the geometric albedo—the latter being a measure of the brightness at zero phase angle, that is, when illumination comes from directly behind the observer—can be derived. In addition, thermal measurements at two or more wavelengths, plus the brightness in the visible-light region, give information on the thermal properties. The thermal inertia, which is a measure of how fast a material heats up or cools off, of most observed asteroids is lower than the bare-rock reference value but greater than that of the lunar regolith; this observation indicates the presence of an insulating layer of granular material on their surface. Moreover, there seems to be a trend, perhaps related to the gravitational environment, that smaller objects (with lower gravity) have a small regolith layer consisting of coarse grains, while larger objects have a thicker regolith layer consisting of fine grains. However, the detailed properties of this regolith layer are poorly known from remote observations. Moreover, the relation between thermal inertia and surface roughness is not straightforward, so one needs to interpret the thermal inertia with caution. + +Near-Earth asteroids that come into close vicinity of the planet can be studied in more details with radar; it provides information about the surface of the asteroid (for example can show the presence of craters and boulders). Such observations were conducted by the Arecibo Observatory in Puerto Rico (305 meter dish) and Goldstone Observatory in California (70 meter dish). Radar observations can also be used for accurate determination of the orbital and rotational dynamics of observed objects. + +Space-based observations + +Both space and ground-based observatories conducted asteroid search programs; the space-based searches are expected to detect more objects because there is no atmosphere to interfere and because they can observe larger portions of the sky. NEOWISE observed more than 100,000 asteroids of the main belt, Spitzer Space Telescope observed more than 700 near-Earth asteroids. These observations determined rough sizes of the majority of observed objects, but provided limited detail about surface properties (such as regolith depth and composition, angle of repose, cohesion, and porosity). + +Asteroids were also studied by the Hubble Space Telescope, such as tracking the colliding asteroids in the main belt, break-up of an asteroid, observing an active asteroid with six comet-like tails, and observing asteroids that were chosen as targets of dedicated missions. + +Space probe missions + +According to Patrick Michel + +The internal structure of asteroids is inferred only from indirect evidence: bulk densities measured by spacecraft, the orbits of natural satellites in the case of asteroid binaries, and the drift of an asteroid's orbit due to the Yarkovsky thermal effect. A spacecraft near an asteroid is perturbed enough by the asteroid's gravity to allow an estimate of the asteroid's mass. The volume is then estimated using a model of the asteroid's shape. Mass and volume allow the derivation of the bulk density, whose uncertainty is usually dominated by the errors made on the volume estimate. The internal porosity of asteroids can be inferred by comparing their bulk density with that of their assumed meteorite analogues, dark asteroids seem to be more porous (>40%) than bright ones. The nature of this porosity is unclear. + +Dedicated missions +The first asteroid to be photographed in close-up was 951 Gaspra in 1991, followed in 1993 by 243 Ida and its moon Dactyl, all of which were imaged by the Galileo probe en route to Jupiter. Other asteroids briefly visited by spacecraft en route to other destinations include 9969 Braille (by Deep Space 1 in 1999), 5535 Annefrank (by Stardust in 2002), 2867 Šteins and 21 Lutetia (by the Rosetta probe in 2008), and 4179 Toutatis (China's lunar orbiter Chang'e 2, which flew within in 2012). + +The first dedicated asteroid probe was NASA's NEAR Shoemaker, which photographed 253 Mathilde in 1997, before entering into orbit around 433 Eros, finally landing on its surface in 2001. It was the first spacecraft to successfully orbit and land on an asteroid. From September to November 2005, the Japanese Hayabusa probe studied 25143 Itokawa in detail and returned samples of its surface to Earth on 13 June 2010, the first asteroid sample-return mission. In 2007, NASA launched the Dawn spacecraft, which orbited 4 Vesta for a year, and observed the dwarf planet Ceres for three years. + +Hayabusa2, a probe launched by JAXA 2014, orbited its target asteroid 162173 Ryugu for more than a year and took samples that were delivered to Earth in 2020. The spacecraft is now on an extended mission and expected to arrive at a new target in 2031. + +NASA launched the OSIRIS-REx in 2016, a sample return mission to asteroid 101955 Bennu. In 2021, the probe departed the asteroid with a sample from its surface. Sample was delivered to Earth in September 2023. The spacecraft continues its extended mission, designated OSIRIS-APEX, to explore near-Earth asteroid Apophis in 2029. + +In 2021, NASA launched Double Asteroid Redirection Test (DART), a mission to test technology for defending Earth against potential hazardous objects. DART deliberately crashed into the minor-planet moon Dimorphos of the double asteroid Didymos in September 2022 to assess the potential of a spacecraft impact to deflect an asteroid from a collision course with Earth. In October, NASA declared DART a success, confirming it had shortened Dimorphos' orbital period around Didymos by about 32 minutes. + +Planned missions + +Currently, several asteroid-dedicated missions are planned by NASA, JAXA, ESA, and CNSA. + +NASA's Lucy, launched in 2021, would visit eight asteroids, one from the main belt and seven Jupiter trojans; it is the first mission to trojans. The main mission would start in 2027. + +NASA's Psyche, launched in October 2023, will study the large metallic asteroid of the same name, and will arrive there in 2029. + +ESA's Hera, planned for launch in 2024, will study the results of the DART impact. It will measure the size and morphology of the crater, and momentum transmitted by the impact, to determine the efficiency of the deflection produced by DART. + +JAXA's DESTINY+ is a mission for a flyby of the Geminids meteor shower parent body 3200 Phaethon, as well as various minor bodies. Its launch is planned for 2024. + +CNSA's Tianwen-2 is planned to launch in 2025. It will use solar electric propulsion to explore the co-orbital near-Earth asteroid 469219 Kamoʻoalewa and the active asteroid 311P/PanSTARRS. The spacecraft will collect samples of the regolith of Kamo'oalewa. + +Asteroid mining + +The concept of asteroid mining was proposed in 1970s. Matt Anderson defines successful asteroid mining as "the development of a mining program that is both financially self-sustaining and profitable to its investors". It has been suggested that asteroids might be used as a source of materials that may be rare or exhausted on Earth, or materials for constructing space habitats. Materials that are heavy and expensive to launch from Earth may someday be mined from asteroids and used for space manufacturing and construction. + +As resource depletion on Earth becomes more real, the idea of extracting valuable elements from asteroids and returning these to Earth for profit, or using space-based resources to build solar-power satellites and space habitats, becomes more attractive. Hypothetically, water processed from ice could refuel orbiting propellant depots. + +From the astrobiological perspective, asteroid prospecting could provide scientific data for the search for extraterrestrial intelligence (SETI). Some astrophysicists have suggested that if advanced extraterrestrial civilizations employed asteroid mining long ago, the hallmarks of these activities might be detectable. + +Mining Ceres is also considered a possibility. As the largest body in the asteroid belt, Ceres could become the main base and transport hub for future asteroid mining infrastructure, allowing mineral resources to be transported to Mars, the Moon, and Earth. Because of its small escape velocity combined with large amounts of water ice, it also could serve as a source of water, fuel, and oxygen for ships going through and beyond the asteroid belt. Transportation from Mars or the Moon to Ceres would be even more energy-efficient than transportation from Earth to the Moon. + +Threats to Earth + +There is increasing interest in identifying asteroids whose orbits cross Earth's, and that could, given enough time, collide with Earth. The three most important groups of near-Earth asteroids are the Apollos, Amors, and Atens. + +The near-Earth asteroid 433 Eros had been discovered as long ago as 1898, and the 1930s brought a flurry of similar objects. In order of discovery, these were: 1221 Amor, 1862 Apollo, 2101 Adonis, and finally 69230 Hermes, which approached within 0.005 AU of Earth in 1937. Astronomers began to realize the possibilities of Earth impact. + +Two events in later decades increased the alarm: the increasing acceptance of the Alvarez hypothesis that an impact event resulted in the Cretaceous–Paleogene extinction, and the 1994 observation of Comet Shoemaker-Levy 9 crashing into Jupiter. The U.S. military also declassified the information that its military satellites, built to detect nuclear explosions, had detected hundreds of upper-atmosphere impacts by objects ranging from one to ten meters across. + +All of these considerations helped spur the launch of highly efficient surveys, consisting of charge-coupled device (CCD) cameras and computers directly connected to telescopes. , it was estimated that 89% to 96% of near-Earth asteroids one kilometer or larger in diameter had been discovered. A list of teams using such systems includes: + Lincoln Near-Earth Asteroid Research (LINEAR) + Near-Earth Asteroid Tracking (NEAT) + Spacewatch + Lowell Observatory Near-Earth-Object Search (LONEOS) + Catalina Sky Survey (CSS) + Pan-STARRS + NEOWISE + Asteroid Terrestrial-impact Last Alert System (ATLAS) + Campo Imperatore Near-Earth Object Survey (CINEOS) + Japanese Spaceguard Association + Asiago-DLR Asteroid Survey (ADAS) + +, the LINEAR system alone had discovered 147,132 asteroids. Among the surveys, 19,266 near-Earth asteroids have been discovered including almost 900 more than in diameter. + +In April 2018, the B612 Foundation reported "It is 100 percent certain we'll be hit [by a devastating asteroid], but we're not 100 percent sure when." In June 2018, the National Science and Technology Council warned that the United States is unprepared for an asteroid impact event, and has developed and released the "National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. According to expert testimony in the United States Congress in 2013, NASA would require at least five years of preparation before a mission to intercept an asteroid could be launched. + +The United Nations declared 30 June to be International Asteroid Day to educate the public about asteroids. The date of International Asteroid Day commemorates the anniversary of the Tunguska asteroid impact over Siberia, on 30 June 1908. + +Chicxulub impact + +The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore near the communities of Chicxulub Puerto and Chicxulub Pueblo, after which the crater is named. It was formed when a large asteroid, about in diameter, struck the Earth. The crater is estimated to be in diameter and in depth. It is one of the largest confirmed impact structures on Earth, and the only one whose peak ring is intact and directly accessible for scientific research. + +In the late 1970s, geologist Walter Alvarez and his father, Nobel Prize–winning scientist Luis Walter Alvarez, put forth their theory that the Cretaceous–Paleogene extinction was caused by an impact event. The main evidence of such an impact was contained in a thin layer of clay present in the K–Pg boundary in Gubbio, Italy. The Alvarezes and colleagues reported that it contained an abnormally high concentration of iridium, a chemical element rare on earth but common in asteroids. Iridium levels in this layer were as much as 160 times above the background level. It was hypothesized that the iridium was spread into the atmosphere when the impactor was vaporized and settled across the Earth's surface among other material thrown up by the impact, producing the layer of iridium-enriched clay. At the time, consensus was not settled on what caused the Cretaceous–Paleogene extinction and the boundary layer, with theories including a nearby supernova, climate change, or a geomagnetic reversal. The Alvarezes' impact hypothesis was rejected by many paleontologists, who believed that the lack of fossils found close to the K–Pg boundary—the "three-meter problem"—suggested a more gradual die-off of fossil species. + +There is broad consensus that the Chicxulub impactor was an asteroid with a carbonaceous chondrite composition, rather than a comet. The impactor was around in diameter—large enough that, if set at sea level, it would have reached taller than Mount Everest. + +Asteroid deflection strategies + +Various collision avoidance techniques have different trade-offs with respect to metrics such as overall performance, cost, failure risks, operations, and technology readiness. There are various methods for changing the course of an asteroid/comet. These can be differentiated by various types of attributes such as the type of mitigation (deflection or fragmentation), energy source (kinetic, electromagnetic, gravitational, solar/thermal, or nuclear), and approach strategy (interception, rendezvous, or remote station). + +Strategies fall into two basic sets: fragmentation and delay. Fragmentation concentrates on rendering the impactor harmless by fragmenting it and scattering the fragments so that they miss the Earth or are small enough to burn up in the atmosphere. Delay exploits the fact that both the Earth and the impactor are in orbit. An impact occurs when both reach the same point in space at the same time, or more correctly when some point on Earth's surface intersects the impactor's orbit when the impactor arrives. Since the Earth is approximately 12,750 km in diameter and moves at approx. 30 km per second in its orbit, it travels a distance of one planetary diameter in about 425 seconds, or slightly over seven minutes. Delaying, or advancing the impactor's arrival by times of this magnitude can, depending on the exact geometry of the impact, cause it to miss the Earth. + +"Project Icarus" was one of the first projects designed in 1967 as a contingency plan in case of collision with 1566 Icarus. The plan relied on the new Saturn V rocket, which did not make its first flight until after the report had been completed. Six Saturn V rockets would be used, each launched at variable intervals from months to hours away from impact. Each rocket was to be fitted with a single 100-megaton nuclear warhead as well as a modified Apollo Service Module and uncrewed Apollo Command Module for guidance to the target. The warheads would be detonated 30 meters from the surface, deflecting or partially destroying the asteroid. Depending on the subsequent impacts on the course or the destruction of the asteroid, later missions would be modified or cancelled as needed. The "last-ditch" launch of the sixth rocket would be 18 hours prior to impact. + +Fiction + +Asteroids and the asteroid belt are a staple of science fiction stories. Asteroids play several potential roles in science fiction: as places human beings might colonize, resources for extracting minerals, hazards encountered by spacecraft traveling between two other points, and as a threat to life on Earth or other inhabited planets, dwarf planets, and natural satellites by potential impact. + +See also + List of asteroid close approaches to Earth + List of exceptional asteroids + Lost minor planet + Meanings of minor-planet names + +Notes + +References + +Further reading + +External links + + + + + NASA Asteroid and Comet Watch site + + + +Minor planets +An allocution, or allocutus, is a formal statement made to the court by the defendant who has been found guilty prior to being sentenced. It is part of the criminal procedure in some jurisdictions using common law. + +Concept +An allocution allows the defendant to explain why the sentence should be lenient. In plea bargains, an allocution may be required of the defendant. The defendant explicitly admits specifically and in detail the actions and their reasons in exchange for a reduced sentence. + +In principle, that removes any doubt as to the exact nature of the defendant's guilt in the matter. + +The term "allocution" is used generally only in jurisdictions in the United States, but there are vaguely similar processes in other common law countries. In many other jurisdictions, it is for the defense lawyer to mitigate on their client's behalf, and the defendant rarely has the opportunity to speak. + +Australia +In Australia, the term allocutus is used by the Clerk of Arraigns or another formal associate of the court. It is generally phrased as, "Prisoner at the Bar, you have been found Guilty by a jury of your peers of the offense of XYZ. Do you have anything to say as to why the sentence of this Court should not now be passed upon you?" The defense counsel will then make a plea in mitigation (also called submissions on penalty) in an attempt to mitigate the relative seriousness of the offense and heavily refer to and rely upon the defendant's previous good character and good works, if any. + +The right to make a plea in mitigation is absolute. If a judge or magistrate refuses to hear such a plea or does not properly consider it, the sentence can be overturned on appeal. + +United States +In most of the United States, defendants are allowed the opportunity to allocute before a sentence is passed. Some jurisdictions hold that as an absolute right. In its absence, a sentence but not the conviction may be overturned, resulting in the need for a new sentencing hearing. In the federal system, Federal Rules of Criminal Procedure 32(i)(4) provides that the court must "address the defendant personally in order to permit the defendant to speak or present any information to mitigate the sentence." + +The federal public defender recommends that defendants speak in terms of how a lenient sentence will be sufficient but not greater than necessary to comply with the statutory directives set forth in . + +See also + Confession (law) + +References + +Criminal procedure +Evidence law +An ( ; Medieval Latin for "he has declared under oath") is a written statement voluntarily made by an affiant or deponent under an oath or affirmation which is administered by a person who is authorized to do so by law. Such a statement is witnessed as to the authenticity of the affiant's signature by a taker of oaths, such as a notary public or commissioner of oaths. An affidavit is a type of verified statement or showing, or in other words, it contains a verification, which means that it is made under oath on penalty of perjury, and this serves as evidence for its veracity and is required in court proceedings. + +Definition + +An affidavit is typically defined as a written declaration or statement that is sworn or affirmed before a person who has authority to administer an oath. There is no general defined form for an affidavit, although for some proceedings an affidavit must satisfy legal or statutory requirements in order to be considered. An affidavit may include, + a commencement which identifies the affiant; + an attestation clause, usually a jurat, at the end certifying that the affiant made the statement under oath on the specified date; + signatures of the affiant and person who administered the oath. +In some cases, an introductory clause, called a preamble, is added attesting that the affiant personally appeared before the authenticating authority. An affidavit may also recite that the statement it records was made under penalty of perjury. + +An affidavit that is prepared for use within the context of litigation may also include a caption that identifies the venue and parties to the relevant judicial proceedings. + +Worldwide + +Australia +On 2 March 2016, the High Court of Australia held that the ACT Uniform Evidence Legislation is neutral in the way sworn evidence and unsworn evidence is treated as being of equal weight. + +United Kingdom +The term "affidavit" is used in the UK. According the UK government website, “The affidavit can be sworn or affirmed by a solicitor, notary or commissioner for oaths (for a charge) or by an authorised member of court staff.” + +India +In Indian law, although an affidavit may be taken as proof of the facts stated therein, the courts have no jurisdiction to admit evidence by way of affidavit. Affidavit is not treated as "evidence" within the meaning of Section 3 of the Evidence Act. However, it was held by the Supreme Court that an affidavit can be used as evidence only if the court so orders for sufficient reasons, namely, the right of the opposite party to have the deponent produced for cross-examination. Therefore, an affidavit cannot ordinarily be used as evidence in absence of a specific order of the court. + +Sri Lanka +In Sri Lanka, under the Oaths Ordinance, with the exception of a court-martial, a person may submit an affidavit signed in the presence of a commissioner for oaths or a justice of the peace. + +Ireland +Affidavits are made in a similar way as to England and Wales, although "make oath" is sometimes omitted. An affirmed affidavit may be substituted for an sworn affidavit in most cases for those opposed to swearing oaths. The person making the affidavit is known as the deponent and signs the affidavit. The affidavit concludes in the standard format "sworn/affirmed (declared) before me, [name of commissioner for oaths/solicitor], a commissioner for oaths (solicitor), on the [date] at [location] in the county/city of [county/city], and I know the deponent", and it is signed and stamped by the commissioner for oaths. It is important that the Commissioner states his/her name clearly, sometimes documents are rejected when the name cannot be ascertained. + +In August 2020, a new method of filing affidavits came into force. Under Section 21 of the Civil Law and Criminal Law (Miscellaneous Provisions) Act 2020 witnesses are no longer required to swear before God or make an affirmation when filing an affidavit. Instead, witnesses will make a non-religious “statement of truth” and, if it is breached, will be liable for up to one year in prison if convicted summarily or, upon conviction on indictment, to a maximum fine of €250,000 or imprisonment for a term not exceeding 5 years, or both. + +This is designed to replace affidavits and statutory declarations in situations where the electronic means of lodgement or filing of documents with the Court provided for in Section 20 is utilised. As of January 2022, it has yet to be adopted widely, and it is expected it will not be used for some time by lay litigants who will still lodge papers in person. + +United States + +In American jurisprudence, under the rules for hearsay, admission of an unsupported affidavit as evidence is unusual (especially if the affiant is not available for cross-examination) with regard to material facts which may be dispositive of the matter at bar. Affidavits from persons who are dead or otherwise incapacitated, or who cannot be located or made to appear, may be accepted by the court, but usually only in the presence of corroborating evidence. An affidavit which reflected a better grasp of the facts close in time to the actual events may be used to refresh a witness's recollection. Materials used to refresh recollection are admissible as evidence. If the affiant is a party in the case, the affiant's opponent may be successful in having the affidavit admitted as evidence, as statements by a party-opponent are admissible through an exception to the hearsay rule. + +Affidavits are typically included in the response to interrogatories. Requests for admissions under Federal Rule of Civil Procedure 36, however, are not required to be sworn. + +When a person signs an affidavit, that person is eligible to take the stand at a trial or evidentiary hearing. One party may wish to summon the affiant to verify the contents of the affidavit, while the other party may want to cross-examine the affiant about the affidavit. + +Some types of motions will not be accepted by the court unless accompanied by an independent sworn statement or other evidence in support of the need for the motion. In such a case, a court will accept an affidavit from the filing attorney in support of the motion, as certain assumptions are made, to wit: The affidavit in place of sworn testimony promotes judicial economy. The lawyer is an officer of the court and knows that a false swearing by them, if found out, could be grounds for severe penalty up to and including disbarment. The lawyer if called upon would be able to present independent and more detailed evidence to prove the facts set forth in his affidavit. + +Affidavits should not be confused with unsworn declarations under penalty of perjury. In federal courts and about 20 states as of 2006, unsworn declarations under penalty of perjury are authorized by statute as acceptable in lieu of affidavits. The key differences are that an unsworn declaration does not bear the jurat of a notary public and the declarant is not required to swear an oath or affirmation. Rather, the signature of the declarant under a carefully worded phrase binding them to the truth of their statements "under penalty of perjury" is deemed as a matter of law to be sufficiently solemn to remind the declarant of their duty to tell the truth, the whole truth, and nothing but the truth. The point of such affidavit substitution statutes is that unsworn declarations can be prepared and executed far more quickly and economically than affidavits, in that the witness need not meet personally with a notary public for the notarization process. + +The acceptance of an affidavit by one society does not confirm its acceptance as a legal document in other jurisdictions. Equally, the acceptance that a lawyer is an officer of the court (for swearing the affidavit) is not a given. This matter is addressed by the use of the apostille, a means of certifying the legalization of a document for international use under the terms of the 1961 Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents. Documents which have been notarized by a notary public, and certain other documents, and then certified with a conformant apostille, are accepted for legal use in all the nations that have signed the Hague Convention. Thus most affidavits now require to be apostilled if used for cross border issues. + +See also + Declaration (law) + Deposition (law) + Fishman Affidavit, a well-known example of an affidavit + Performativity + Statutory declaration + Sworn declaration + +References + +Evidence law +Legal documents +Notary +Aries is one of the constellations of the zodiac. It is located in the Northern celestial hemisphere between Pisces to the west and Taurus to the east. The name Aries is Latin for ram. Its old astronomical symbol is (♈︎). It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations. It is a mid-sized constellation ranking 39th in overall size, with an area of 441 square degrees (1.1% of the celestial sphere). + +Aries has represented a ram since late Babylonian times. Before that, the stars of Aries formed a farmhand. Different cultures have incorporated the stars of Aries into different constellations including twin inspectors in China and a porpoise in the Marshall Islands. Aries is a relatively dim constellation, possessing only four bright stars: Hamal (Alpha Arietis, second magnitude), Sheratan (Beta Arietis, third magnitude), Mesarthim (Gamma Arietis, fourth magnitude), and 41 Arietis (also fourth magnitude). The few deep-sky objects within the constellation are quite faint and include several pairs of interacting galaxies. Several meteor showers appear to radiate from Aries, including the Daytime Arietids and the Epsilon Arietids. + +History and mythology + +Aries is now recognized as an official constellation, albeit as a specific region of the sky, by the International Astronomical Union. It was originally defined in ancient texts as a specific pattern of stars, and has remained a constellation since ancient times; it now includes the ancient pattern and the surrounding stars. In the description of the Babylonian zodiac given in the clay tablets known as the MUL.APIN, the constellation, now known as Aries, was the final station along the ecliptic. The MUL.APIN was a comprehensive table of the rising and settings of stars, which likely served as an agricultural calendar. Modern-day Aries was known as , "The Agrarian Worker" or "The Hired Man". Although likely compiled in the 12th or 11th century BC, the MUL.APIN reflects a tradition that marks the Pleiades as the vernal equinox, which was the case with some precision at the beginning of the Middle Bronze Age. The earliest identifiable reference to Aries as a distinct constellation comes from the boundary stones that date from 1350 to 1000 BC. On several boundary stones, a zodiacal ram figure is distinct from the other characters. The shift in identification from the constellation as the Agrarian Worker to the Ram likely occurred in later Babylonian tradition because of its growing association with Dumuzi the Shepherd. By the time the MUL.APIN was created—in 1000 BC—modern Aries was identified with both Dumuzi's ram and a hired labourer. The exact timing of this shift is difficult to determine due to the lack of images of Aries or other ram figures. + +In ancient Egyptian astronomy, Aries was associated with the god Amun-Ra, who was depicted as a man with a ram's head and represented fertility and creativity. Because it was the location of the vernal equinox, it was called the "Indicator of the Reborn Sun". During the times of the year when Aries was prominent, priests would process statues of Amon-Ra to temples, a practice that was modified by Persian astronomers centuries later. Aries acquired the title of "Lord of the Head" in Egypt, referring to its symbolic and mythological importance. + +Aries was not fully accepted as a constellation until classical times. In Hellenistic astrology, the constellation of Aries is associated with the golden ram of Greek mythology that rescued Phrixus and Helle on orders from Hermes, taking Phrixus to the land of Colchis. Phrixus and Helle were the son and daughter of King Athamas and his first wife Nephele. The king's second wife, Ino, was jealous and wished to kill his children. To accomplish this, she induced famine in Boeotia, then falsified a message from the Oracle of Delphi that said Phrixus must be sacrificed to end the famine. Athamas was about to sacrifice his son atop Mount Laphystium when Aries, sent by Nephele, arrived. Helle fell off of Aries's back in flight and drowned in the Dardanelles, also called the Hellespont in her honour. + +Historically, Aries has been depicted as a crouched, wingless ram with its head turned towards Taurus. Ptolemy asserted in his Almagest that Hipparchus depicted Alpha Arietis as the ram's muzzle, though Ptolemy did not include it in his constellation figure. Instead, it was listed as an "unformed star", and denoted as "the star over the head". John Flamsteed, in his Atlas Coelestis, followed Ptolemy's description by mapping it above the figure's head. Flamsteed followed the general convention of maps by depicting Aries lying down. Astrologically, Aries has been associated with the head and its humors. It was strongly associated with Mars, both the planet and the god. It was considered to govern Western Europe and Syria and to indicate a strong temper in a person. + +The First Point of Aries, the location of the vernal equinox, is named for the constellation. This is because the Sun crossed the celestial equator from south to north in Aries more than two millennia ago. Hipparchus defined it in 130 BC. as a point south of Gamma Arietis. Because of the precession of the equinoxes, the First Point of Aries has since moved into Pisces and will move into Aquarius by around 2600 AD. The Sun now appears in Aries from late April through mid-May, though the constellation is still associated with the beginning of spring. + +Medieval Muslim astronomers depicted Aries in various ways. Astronomers like al-Sufi saw the constellation as a ram, modelled on the precedent of Ptolemy. However, some Islamic celestial globes depicted Aries as a nondescript four-legged animal with what may be antlers instead of horns. Some early Bedouin observers saw a ram elsewhere in the sky; this constellation featured the Pleiades as the ram's tail. The generally accepted Arabic formation of Aries consisted of thirteen stars in a figure along with five "unformed" stars, four of which were over the animal's hindquarters and one of which was the disputed star over Aries's head. Al-Sufi's depiction differed from both other Arab astronomers' and Flamsteed's, in that his Aries was running and looking behind itself. + +The obsolete constellations of Aries (Apes/Vespa/Lilium/Musca (Borealis)) all centred on the same the northern stars. In 1612, Petrus Plancius introduced Apes, a constellation representing a bee. In 1624, the same stars were used by Jakob Bartsch as for Vespa, representing a wasp. In 1679, Augustin Royer used these stars for his constellation Lilium, representing the fleur-de-lis. None of these constellations became widely accepted. Johann Hevelius renamed the constellation "Musca" in 1690 in his Firmamentum Sobiescianum. To differentiate it from Musca, the southern fly, it was later renamed Musca Borealis but it did not gain acceptance and its stars were ultimately officially reabsorbed into Aries. The asterism involved was 33, 35, 39, and 41 Arietis. + +In 1922, the International Astronomical Union defined its recommended three-letter abbreviation, "Ari". The official boundaries of Aries were defined in 1930 by Eugène Delporte as a polygon of 12 segments. Its right ascension is between 1h 46.4m and 3h 29.4m and its declination is between 10.36° and 31.22° in the equatorial coordinate system. + +In non-Western astronomy +In traditional Chinese astronomy, stars from Aries were used in several constellations. The brightest stars—Alpha, Beta, and Gamma Arietis—formed a constellation called Lou (婁), variously translated as "bond", "lasso", and "sickle", which was associated with the ritual sacrifice of cattle. This name was shared by the 16th lunar mansion, the location of the full moon closest to the autumnal equinox. This constellation has also been associated with harvest-time as it could represent a woman carrying a basket of food on her head. 35, 39, and 41 Arietis were part of a constellation called Wei (胃), which represented a fat abdomen and was the namesake of the 17th lunar mansion, which represented granaries. Delta and Zeta Arietis were a part of the constellation Tianyin (天陰), thought to represent the Emperor's hunting partner. Zuogeng (左更), a constellation depicting a marsh and pond inspector, was composed of Mu, Nu, Omicron, Pi, and Sigma Arietis. He was accompanied by Yeou-kang, a constellation depicting an official in charge of pasture distribution. + +In a similar system to the Chinese, the first lunar mansion in Hindu astronomy was called "Aswini", after the traditional names for Beta and Gamma Arietis, the Aswins. Because the Hindu new year began with the vernal equinox, the Rig Veda contains over 50 new-year's related hymns to the twins, making them some of the most prominent characters in the work. Aries itself was known as "Aja" and "Mesha". In Hebrew astronomy Aries was named "Taleh"; it signified either Simeon or Gad, and generally symbolizes the "Lamb of the World". The neighboring Syrians named the constellation "Amru", and the bordering Turks named it "Kuzi". Half a world away, in the Marshall Islands, several stars from Aries were incorporated into a constellation depicting a porpoise, along with stars from Cassiopeia, Andromeda, and Triangulum. Alpha, Beta, and Gamma Arietis formed the head of the porpoise, while stars from Andromeda formed the body and the bright stars of Cassiopeia formed the tail. Other Polynesian peoples recognized Aries as a constellation. The Marquesas islanders called it Na-pai-ka; the Māori constellation Pipiri may correspond to modern Aries as well. In indigenous Peruvian astronomy, a constellation with most of the same stars as Aries existed. It was called the "Market Moon" and the "Kneeling Terrace", as a reminder of when to hold the annual harvest festival, Ayri Huay. + +Features + +Stars + +Aries has three prominent stars forming an asterism, designated Alpha, Beta, and Gamma Arietis by Johann Bayer. Alpha (Hamal) and Beta (Sheratan) are commonly used for navigation. There is also one other star above the fourth magnitude, 41 Arietis (Bharani). α Arietis, called Hamal, is the brightest star in Aries. Its traditional name is derived from the Arabic word for "lamb" or "head of the ram" (ras al-hamal), which references Aries's mythological background. With a spectral class of K2 and a luminosity class of III, it is an orange giant with an apparent visual magnitude of 2.00, which lies 66 light-years from Earth. Hamal has a luminosity of and its absolute magnitude is −0.1. + +β Arietis, also known as Sheratan, is a blue-white star with an apparent visual magnitude of 2.64. Its traditional name is derived from "sharatayn", the Arabic word for "the two signs", referring to both Beta and Gamma Arietis in their position as heralds of the vernal equinox. The two stars were known to the Bedouin as "qarna al-hamal", "horns of the ram". It is 59 light-years from Earth. It has a luminosity of and its absolute magnitude is 2.1. It is a spectroscopic binary star, one in which the companion star is only known through analysis of the spectra. The spectral class of the primary is A5. Hermann Carl Vogel determined that Sheratan was a spectroscopic binary in 1903; its orbit was determined by Hans Ludendorff in 1907. It has since been studied for its eccentric orbit. + +γ Arietis, with a common name of Mesarthim, is a binary star with two white-hued components, located in a rich field of magnitude 8–12 stars. Its traditional name has conflicting derivations. It may be derived from a corruption of "al-sharatan", the Arabic word meaning "pair" or a word for "fat ram". However, it may also come from the Sanskrit for "first star of Aries" or the Hebrew for "ministerial servants", both of which are unusual languages of origin for star names. Along with Beta Arietis, it was known to the Bedouin as "qarna al-hamal". The primary is of magnitude 4.59 and the secondary is of magnitude 4.68. The system is 164 light-years from Earth. The two components are separated by 7.8 arcseconds, and the system as a whole has an apparent magnitude of 3.9. The primary has a luminosity of and the secondary has a luminosity of ; the primary is an A-type star with an absolute magnitude of 0.2 and the secondary is a B9-type star with an absolute magnitude of 0.4. The angle between the two components is 1°. Mesarthim was discovered to be a double star by Robert Hooke in 1664, one of the earliest such telescopic discoveries. The primary, γ1 Arietis, is an Alpha² Canum Venaticorum variable star that has a range of 0.02 magnitudes and a period of 2.607 days. It is unusual because of its strong silicon emission lines. + +The constellation is home to several double stars, including Epsilon, Lambda, and Pi Arietis. ε Arietis is a binary star with two white components. The primary is of magnitude 5.2 and the secondary is of magnitude 5.5. The system is 290 light-years from Earth. Its overall magnitude is 4.63, and the primary has an absolute magnitude of 1.4. Its spectral class is A2. The two components are separated by 1.5 arcseconds. λ Arietis is a wide double star with a white-hued primary and a yellow-hued secondary. The primary is of magnitude 4.8 and the secondary is of magnitude 7.3. The primary is 129 light-years from Earth. It has an absolute magnitude of 1.7 and a spectral class of F0. The two components are separated by 36 arcseconds at an angle of 50°; the two stars are located 0.5° east of 7 Arietis. π Arietis is a close binary star with a blue-white primary and a white secondary. The primary is of magnitude 5.3 and the secondary is of magnitude 8.5. The primary is 776 light-years from Earth. The primary itself is a wide double star with a separation of 25.2 arcseconds; the tertiary has a magnitude of 10.8. The primary and secondary are separated by 3.2 arcseconds. + +Most of the other stars in Aries visible to the naked eye have magnitudes between 3 and 5. δ Ari, called Boteïn, is a star of magnitude 4.35, 170 light-years away. It has an absolute magnitude of −0.1 and a spectral class of K2. ζ Arietis is a star of magnitude 4.89, 263 light-years away. Its spectral class is A0 and its absolute magnitude is 0.0. 14 Arietis is a star of magnitude 4.98, 288 light-years away. Its spectral class is F2 and its absolute magnitude is 0.6. 39 Arietis (Lilii Borea) is a similar star of magnitude 4.51, 172 light-years away. Its spectral class is K1 and its absolute magnitude is 0.0. 35 Arietis is a dim star of magnitude 4.55, 343 light-years away. Its spectral class is B3 and its absolute magnitude is −1.7. 41 Arietis, known both as c Arietis and Nair al Butain, is a brighter star of magnitude 3.63, 165 light-years away. Its spectral class is B8 and it has a luminosity of . Its absolute magnitude is −0.2. 53 Arietis is a runaway star of magnitude 6.09, 815 light-years away. Its spectral class is B2. It was likely ejected from the Orion Nebula approximately five million years ago, possibly due to supernovae. Finally, Teegarden's Star is the closest star to Earth in Aries. It is a red dwarf of magnitude 15.14 and spectral class M6.5V. With a proper motion of 5.1 arcseconds per year, it is the 24th closest star to Earth overall. + +Aries has its share of variable stars, including R and U Arietis, Mira-type variable stars, and T Arietis, a semi-regular variable star. R Arietis is a Mira variable star that ranges in magnitude from a minimum of 13.7 to a maximum of 7.4 with a period of 186.8 days. It is 4,080 light-years away. U Arietis is another Mira variable star that ranges in magnitude from a minimum of 15.2 to a maximum of 7.2 with a period of 371.1 days. T Arietis is a semiregular variable star that ranges in magnitude from a minimum of 11.3 to a maximum of 7.5 with a period of 317 days. It is 1,630 light-years away. One particularly interesting variable in Aries is SX Arietis, a rotating variable star considered to be the prototype of its class, helium variable stars. SX Arietis stars have very prominent emission lines of Helium I and Silicon III. They are normally main-sequence B0p—B9p stars, and their variations are not usually visible to the naked eye. Therefore, they are observed photometrically, usually having periods that fit in the course of one night. Similar to Alpha² Canum Venaticorum variables, SX Arietis stars have periodic changes in their light and magnetic field, which correspond to the periodic rotation; they differ from the Alpha² Canum Venaticorum variables in their higher temperature. There are between 39 and 49 SX Arietis variable stars currently known; ten are noted as being "uncertain" in the General Catalog of Variable Stars. + +Deep sky objects + +NGC 772 is a spiral galaxy with an integrated magnitude of 10.3, located southeast of β Arietis and 15 arcminutes west of 15 Arietis. It is a relatively bright galaxy and shows obvious nebulosity and ellipticity in an amateur telescope. It is 7.2 by 4.2 arcminutes, meaning that its surface brightness, magnitude 13.6, is significantly lower than its integrated magnitude. NGC 772 is a class SA(s)b galaxy, which means that it is an unbarred spiral galaxy without a ring that possesses a somewhat prominent bulge and spiral arms that are wound somewhat tightly. The main arm, on the northwest side of the galaxy, is home to many star forming regions; this is due to previous gravitational interactions with other galaxies. NGC 772 has a small companion galaxy, NGC 770, that is about 113,000 light-years away from the larger galaxy. The two galaxies together are also classified as Arp 78 in the Arp peculiar galaxy catalog. NGC 772 has a diameter of 240,000 light-years and the system is 114 million light-years from Earth. Another spiral galaxy in Aries is NGC 673, a face-on class SAB(s)c galaxy. It is a weakly barred spiral galaxy with loosely wound arms. It has no ring and a faint bulge and is 2.5 by 1.9 arcminutes. It has two primary arms with fragments located farther from the core. 171,000 light-years in diameter, NGC 673 is 235 million light-years from Earth. + +NGC 678 and NGC 680 are a pair of galaxies in Aries that are only about 200,000 light-years apart. Part of the NGC 691 group of galaxies, both are at a distance of approximately 130 million light-years. NGC 678 is an edge-on spiral galaxy that is 4.5 by 0.8 arcminutes. NGC 680, an elliptical galaxy with an asymmetrical boundary, is the brighter of the two at magnitude 12.9; NGC 678 has a magnitude of 13.35. Both galaxies have bright cores, but NGC 678 is the larger galaxy at a diameter of 171,000 light-years; NGC 680 has a diameter of 72,000 light-years. NGC 678 is further distinguished by its prominent dust lane. NGC 691 itself is a spiral galaxy slightly inclined to our line of sight. It has multiple spiral arms and a bright core. Because it is so diffuse, it has a low surface brightness. It has a diameter of 126,000 light-years and is 124 million light-years away. NGC 877 is the brightest member of an 8-galaxy group that also includes NGC 870, NGC 871, and NGC 876, with a magnitude of 12.53. It is 2.4 by 1.8 arcminutes and is 178 million light-years away with a diameter of 124,000 light-years. Its companion is NGC 876, which is about 103,000 light-years from the core of NGC 877. They are interacting gravitationally, as they are connected by a faint stream of gas and dust. Arp 276 is a different pair of interacting galaxies in Aries, consisting of NGC 935 and IC 1801. + +NGC 821 is an E6 elliptical galaxy. It is unusual because it has hints of an early spiral structure, which is normally only found in lenticular and spiral galaxies. NGC 821 is 2.6 by 2.0 arcminutes and has a visual magnitude of 11.3. Its diameter is 61,000 light-years and it is 80 million light-years away. Another unusual galaxy in Aries is Segue 2, a dwarf and satellite galaxy of the Milky Way, recently discovered to be a potential relic of the epoch of reionization. + +Meteor showers +Aries is home to several meteor showers. The Daytime Arietid meteor shower is one of the strongest meteor showers that occurs during the day, lasting from 22 May to 2 July. It is an annual shower associated with the Marsden group of comets that peaks on 7 June with a maximum zenithal hourly rate of 54 meteors. Its parent body may be the asteroid Icarus. The meteors are sometimes visible before dawn, because the radiant is 32 degrees away from the Sun. They usually appear at a rate of 1–2 per hour as "earthgrazers", meteors that last several seconds and often begin at the horizon. Because most of the Daytime Arietids are not visible to the naked eye, they are observed in the radio spectrum. This is possible because of the ionized gas they leave in their wake. Other meteor showers radiate from Aries during the day; these include the Daytime Epsilon Arietids and the Northern and Southern Daytime May Arietids. The Jodrell Bank Observatory discovered the Daytime Arietids in 1947 when James Hey and G. S. Stewart adapted the World War II-era radar systems for meteor observations. + +The Delta Arietids are another meteor shower radiating from Aries. Peaking on 9 December with a low peak rate, the shower lasts from 8 December to 14 January, with the highest rates visible from 8 to 14 December. The average Delta Arietid meteor is very slow, with an average velocity of per second. However, this shower sometimes produces bright fireballs. This meteor shower has northern and southern components, both of which are likely associated with 1990 HA, a near-Earth asteroid. + +The Autumn Arietids also radiate from Aries. The shower lasts from 7 September to 27 October and peaks on 9 October. Its peak rate is low. The Epsilon Arietids appear from 12 to 23 October. Other meteor showers radiating from Aries include the October Delta Arietids, Daytime Epsilon Arietids, Daytime May Arietids, Sigma Arietids, Nu Arietids, and Beta Arietids. The Sigma Arietids, a class IV meteor shower, are visible from 12 to 19 October, with a maximum zenithal hourly rate of less than two meteors per hour on 19 October. + +Planetary systems +Aries contains several stars with extrasolar planets. HIP 14810, a G5 type star, is orbited by three giant planets (those more than ten times the mass of Earth). HD 12661, like HIP 14810, is a G-type main sequence star, slightly larger than the Sun, with two orbiting planets. One planet is 2.3 times the mass of Jupiter, and the other is 1.57 times the mass of Jupiter. HD 20367 is a G0 type star, approximately the size of the Sun, with one orbiting planet. The planet, discovered in 2002, has a mass 1.07 times that of Jupiter and orbits every 500 days. In 2019, scientists conducting the CARMENES survey at the Calar Alto Observatory announced evidence of two Earth-mass exoplanets orbiting Teegarden's star, located in Aries, within its habitable zone. The star is a small red dwarf with only around a tenth of the mass and radius of the Sun. It has a large radial velocity. + +See also + Aries (Chinese astronomy) + +References + +Explanatory notes + +Citations + +Bibliography + +Online sources + + + + + + + + + + + + + +SIMBAD + +External links + + The Deep Photographic Guide to the Constellations: Aries + The clickable Aries + Star Tales – Aries + Warburg Institute Iconographic Database (medieval and early modern images of Aries) + + +Constellations +Constellations listed by Ptolemy +Northern constellations +Aquarius is an equatorial constellation of the zodiac, between Capricornus and Pisces. Its name is Latin for "water-carrier" or "cup-carrier", and its old astronomical symbol is (♒︎), a representation of water. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river. + +At apparent magnitude 2.9, Beta Aquarii is the brightest star in the constellation. + +History and mythology +Aquarius is identified as "The Great One" in the Babylonian star catalogues and represents the god Ea himself, who is commonly depicted holding an overflowing vase. The Babylonian star-figure appears on entitlement stones and cylinder seals from the second millennium. It contained the winter solstice in the Early Bronze Age. In Old Babylonian astronomy, Ea was the ruler of the southernmost quarter of the Sun's path, the "Way of Ea", corresponding to the period of 45 days on either side of winter solstice. Aquarius was also associated with the destructive floods that the Babylonians regularly experienced, and thus was negatively connoted. In Ancient Egypt astronomy, Aquarius was associated with the annual flood of the Nile; the banks were said to flood when Aquarius put his jar into the river, beginning spring. + +In the Greek tradition, the constellation came to be represented simply as a single vase from which a stream poured down to Piscis Austrinus. The name in the Hindu zodiac is likewise kumbha "water-pitcher". + +In Greek mythology, Aquarius is sometimes associated with Deucalion, the son of Prometheus who built a ship with his wife Pyrrha to survive an imminent flood. They sailed for nine days before washing ashore on Mount Parnassus. Aquarius is also sometimes identified with beautiful Ganymede, a youth in Greek mythology and the son of Trojan king Tros, who was taken to Mount Olympus by Zeus to act as cup-carrier to the gods. Neighboring Aquila represents the eagle, under Zeus' command, that snatched the young boy; some versions of the myth indicate that the eagle was in fact Zeus transformed. An alternative version of the tale recounts Ganymede's kidnapping by the goddess of the dawn, Eos, motivated by her affection for young men; Zeus then stole him from Eos and employed him as cup-bearer. Yet another figure associated with the water bearer is Cecrops I, a king of Athens who sacrificed water instead of wine to the gods. + +Depictions + +In the first century, Ptolemy's Almagest established the common Western depiction of Aquarius. His water jar, an asterism itself, consists of Gamma, Pi, Eta, and Zeta Aquarii; it pours water in a stream of more than 20 stars terminating with Fomalhaut, now assigned solely to Piscis Austrinus. The water bearer's head is represented by 5th magnitude 25 Aquarii while his left shoulder is Beta Aquarii; his right shoulder and forearm are represented by Alpha and Gamma Aquarii respectively. + +In Eastern astronomy +In Chinese astronomy, the stream of water flowing from the Water Jar was depicted as the "Army of Yu-Lin" (Yu-lim-kiun or Yulinjun, Hanzi: 羽林君). The name "Yu-lin" means "feathers and forests", referring to the numerous light-footed soldiers from the northern reaches of the empire represented by these faint stars. The constellation's stars were the most numerous of any Chinese constellation, numbering 45, the majority of which were located in modern Aquarius. The celestial army was protected by the wall Leibizhen (垒壁阵), which counted Iota, Lambda, Phi, and Sigma Aquarii among its 12 stars. 88, 89, and 98 Aquarii represent Fou-youe, the axes used as weapons and for hostage executions. Also in Aquarius is Loui-pi-tchin, the ramparts that stretch from 29 and 27 Piscium and 33 and 30 Aquarii through Phi, Lambda, Sigma, and Iota Aquarii to Delta, Gamma, Kappa, and Epsilon Capricorni. + +Near the border with Cetus, the axe Fuyue was represented by three stars; its position is disputed and may have instead been located in Sculptor. Tienliecheng also has a disputed position; the 13-star castle replete with ramparts may have possessed Nu and Xi Aquarii but may instead have been located south in Piscis Austrinus. The Water Jar asterism was seen to the ancient Chinese as the tomb, Fenmu. Nearby, the emperors' mausoleum Xiuliang stood, demarcated by Kappa Aquarii and three other collinear stars. Ku ("crying") and Qi ("weeping"), each composed of two stars, were located in the same region. + +Three of the Chinese lunar mansions shared their name with constellations. Nu, also the name for the 10th lunar mansion, was a handmaiden represented by Epsilon, Mu, 3, and 4 Aquarii. The 11th lunar mansion shared its name with the constellation Xu ("emptiness"), formed by Beta Aquarii and Alpha Equulei; it represented a bleak place associated with death and funerals. Wei, the rooftop and 12th lunar mansion, was a V-shaped constellation formed by Alpha Aquarii, Theta Pegasi, and Epsilon Pegasi; it shared its name with two other Chinese constellations, in modern-day Scorpius and Aries. + +Features + +Stars + +Despite both its prominent position on the zodiac and its large size, Aquarius has no particularly bright stars, its four brightest stars being less than However, recent research has shown that there are several stars lying within its borders that possess planetary systems. + +The two brightest stars, α Aquarii and β Aquarii, are luminous yellow supergiants, of spectral types G0Ib and G2Ib respectively, that were once hot blue-white B-class main sequence stars 5 to 9 times as massive as the Sun. The two are also moving through space perpendicular to the plane of the Milky Way. Just shading α, β Aquarii is the brightest star in Aquarius with apparent It also has the proper name of Sadalsuud. Having cooled and swollen to around 50 times the Sun's diameter, it is around 2200 times as luminous as the Sun. It is around 6.4 times as massive as the Sun and around 56 million years old. Sadalsuud is from Earth. α Aquarii, also known as Sadalmelik, has apparent It is distant from Earth, and is around 6.5 times as massive as the Sun, and 3000 times as luminous. It is 53 million years old. + +γ Aquarii, also called Sadachbia, is a white main sequence star of spectral type star of spectral type A0V that is between 158 and 315 million years old and is around 2.5 times the Sun's mass (), and double its radius.

Gliese 876, one of the nearest stars to Earth at a distance of 15 light-years, was the first red dwarf star to be found to possess a planetary system. It is orbited by four planets, including one terrestrial planet 6.6 times the mass of Earth. The planets vary in orbital period from 2 days to 124 days. 91 Aquarii is an orange giant star orbited by one planet, 91 Aquarii b. The planet's mass is 2.9 times the mass of Jupiter, and its orbital period is 182 days. Gliese 849 is a red dwarf star orbited by the first known long-period Jupiter-like planet, Gliese 849 b. The planet's mass is 0.99 times that of Jupiter and its orbital period is 1,852 days. + +There are also less-prominent systems in Aquarius. WASP-6, a type G8 star of magnitude 12.4, is host to one exoplanet, WASP-6 b. The star is 307 parsecs from Earth and has a mass of 0.888 solar masses and a radius of 0.87 solar radii. WASP-6 b was discovered in 2008 by the transit method. It orbits its parent star every 3.36 days at a distance of 0.042 astronomical units (AU). It is 0.503 Jupiter masses but has a proportionally larger radius of 1.224 Jupiter radii. HD 206610, a K0 star located 194 parsecs from Earth, is host to one planet, HD 206610 b. The host star is larger than the Sun; more massive at 1.56 solar masses and larger at 6.1 solar radii. The planet was discovered by the radial velocity method in 2010 and has a mass of 2.2 Jupiter masses. It orbits every 610 days at a distance of 1.68 AU. Much closer to its sun is WASP-47 b, which orbits every 4.15 days only 0.052 AU from its sun, yellow dwarf (G9V) WASP-47. WASP-47 is close in size to the Sun, having a radius of 1.15 solar radii and a mass even closer at 1.08 solar masses. WASP-47 b was discovered in 2011 by the transit method, like WASP-6 b. It is slightly larger than Jupiter with a mass of 1.14 Jupiter masses and a radius of 1.15 Jupiter masses. + +There are several more single-planet systems in Aquarius. HD 210277, a magnitude 6.63 yellow star located 21.29 parsecs from Earth, is host to one known planet: HD 210277 b. The 1.23 Jupiter mass planet orbits at nearly the same distance as Earth orbits the Sun1.1 AU, though its orbital period is significantly longer at around 442 days. HD 210277 b was discovered earlier than most of the other planets in Aquarius, detected by the radial velocity method in 1998. The star it orbits resembles the Sun beyond their similar spectral class; it has a radius of 1.1 solar radii and a mass of 1.09 solar masses. HD 212771 b, a larger planet at 2.3 Jupiter masses, orbits host star HD 212771 at a distance of 1.22 AU. The star itself, barely below the threshold of naked-eye visibility at magnitude 7.6, is a G8IV (yellow subgiant) star located 131 parsecs from Earth. Though it has a similar mass to the Sun1.15 solar massesit is significantly less dense with its radius of 5 solar radii. Its lone planet was discovered in 2010 by the radial velocity method, like several other exoplanets in the constellation. + +As of 2013, there were only two known multiple-planet systems within the bounds of Aquarius: the Gliese 876 and HD 215152 systems. The former is quite prominent; the latter has only two planets and has a host star farther away at 21.5 parsecs. The HD 215152 system consists of the planets HD 215152 b and HD 215152 c orbiting their K0-type, magnitude 8.13 sun. Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star. HD 215152 c is the larger at 0.0097 Jupiter masses (still significantly larger than the Earth, which weighs in at 0.00315 Jupiter masses); its smaller sibling is barely smaller at 0.0087 Jupiter masses. The error in the mass measurements (0.0032 and respectively) is large enough to make this discrepancy statistically insignificant. HD 215152 c also orbits further from the star than HD 215152 b, 0.0852 AU compared to 0.0652. + +On 23 February 2017, NASA announced that ultracool dwarf star TRAPPIST-1 in Aquarius has seven Earth-like rocky planets. Of these, as many as four may lie within the system's habitable zone, and may have liquid water on their surfaces. The discovery of the TRAPPIST-1 system is seen by astronomers as a significant step toward finding life beyond Earth. + +Deep sky objects + +Because of its position away from the galactic plane, the majority of deep-sky objects in Aquarius are galaxies, globular clusters, and planetary nebulae. Aquarius contains three deep sky objects that are in the Messier catalog: the globular clusters Messier 2, Messier 72, and the asterism Messier 73. While M73 was originally catalogued as a sparsely populated open cluster, modern analysis indicates the 6 main stars are not close enough together to fit this definition, reclassifying M73 as an asterism. Two well-known planetary nebulae are also located in Aquarius: the Saturn Nebula (NGC 7009), to the southeast of μ Aquarii; and the famous Helix Nebula (NGC 7293), southwest of δ Aquarii. + +M2, also catalogued as NGC 7089, is a rich globular cluster located approximately 37,000 light-years from Earth. At magnitude 6.5, it is viewable in small-aperture instruments, but a 100 mm aperture telescope is needed to resolve any stars. M72, also catalogued as NGC 6981, is a small 9th magnitude globular cluster located approximately 56,000 light-years from Earth. M73, also catalogued as NGC 6994, is an open cluster with highly disputed status. + +Aquarius is also home to several planetary nebulae. NGC 7009, also known as the Saturn Nebula, is an 8th magnitude planetary nebula located 3,000 light-years from Earth. It was given its moniker by the 19th century astronomer Lord Rosse for its resemblance to the planet Saturn in a telescope; it has faint protrusions on either side that resemble Saturn's rings. It appears blue-green in a telescope and has a central star of magnitude 11.3. Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth. However, because it is so large, it is only viewable as a very faint object, though it has a fairly high integrated magnitude of 6.0. + +One of the visible galaxies in Aquarius is NGC 7727, of particular interest for amateur astronomers who wish to discover or observe supernovae. A spiral galaxy (type S), it has an integrated magnitude of 10.7 and is 3 by 3 arcseconds. NGC 7252 is a tangle of stars resulting from the collision of two large galaxies and is known as the Atoms-for-Peace galaxy because of its resemblance to a cartoon atom. + +Meteor showers +There are three major meteor showers with radiants in Aquarius: the Eta Aquariids, the Delta Aquariids, and the Iota Aquariids. + +The Eta Aquariids are the strongest meteor shower radiating from Aquarius. It peaks between 5 and 6 May with a rate of approximately 35 meteors per hour. Originally discovered by Chinese astronomers in 401, Eta Aquariids can be seen coming from the Water Jar beginning on 21 April and as late as 12 May. The parent body of the shower is Halley's Comet, a periodic comet. Fireballs are common shortly after the peak, approximately between 9 May and 11 May. The normal meteors appear to have yellow trails. + +The Delta Aquariids is a double radiant meteor shower that peaks first on 29 July and second on 6 August. The first radiant is located in the south of the constellation, while the second radiant is located in the northern circlet of Pisces asterism. The southern radiant's peak rate is about 20 meteors per hour, while the northern radiant's peak rate is about 10 meteors per hour. + +The Iota Aquariids is a fairly weak meteor shower that peaks on 6 August, with a rate of approximately 8 meteors per hour. + +Astrology + +, the Sun appears in the constellation Aquarius from 16 February to 12 March. In tropical astrology, the Sun is considered to be in the sign Aquarius from 20 January to 19 February, and in sidereal astrology, from 15 February to 14 March. + +Aquarius is also associated with the Age of Aquarius, a concept popular in 1960s counterculture and Medieval Alchemy. The date of the start of The Age of Aquarius is a topic of much debate. + +Notes + +See also + Aquarius (Chinese astronomy) + +References + +External links + + The Deep Photographic Guide to the Constellations: Aquarius + The clickable Aquarius + Warburg Institute Iconographic Database (medieval and early modern images of Aquarius) + + +Constellations +Equatorial constellations +Constellations listed by Ptolemy +is hand-drawn and computer-generated animation originating from Japan. Outside Japan and in English, anime refers specifically to animation produced in Japan. However, in Japan and in Japanese, (a term derived from a shortening of the English word animation) describes all animated works, regardless of style or origin. Many works of animation with a similar style to Japanese animation are also produced outside Japan. Video games sometimes also feature themes and artstyles that can be considered as "anime". + +The earliest commercial Japanese animations date to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, directly to home media, and over the Internet. In addition to original works, anime are often adaptations of Japanese comics (manga), light novels, or video games. It is classified into numerous genres targeting various broad and niche audiences. + +Anime is a diverse medium with distinctive production methods that have adapted in response to emergent technologies. It combines graphic art, characterization, cinematography, and other forms of imaginative and individualistic techniques. Compared to Western animation, anime production generally focuses less on movement, and more on the detail of settings and use of "camera effects", such as panning, zooming, and angle shots. Diverse art styles are used, and character proportions and features can be quite varied, with a common characteristic feature being large and emotive eyes. + +The anime industry consists of over 430 production companies, including major studios such as Studio Ghibli, Kyoto Animation, Sunrise, Bones, Ufotable, MAPPA, Wit Studio, CoMix Wave Films, Production I.G and Toei Animation. Since the 1980s, the medium has also seen widespread international success with the rise of foreign dubbed, subtitled programming, and since the 2010s its increasing distribution through streaming services and a widening demographic embrace of anime culture, both within Japan and worldwide. Japanese animation accounted for 60% of the world's animated television shows. + +Etymology +As a type of animation, anime is an art form that comprises many genres found in other mediums; it is sometimes mistakenly classified as a genre itself. In Japanese, the term anime is used to refer to all animated works, regardless of style or origin. English-language dictionaries typically define anime () as "a style of Japanese animation" or as "a style of animation originating in Japan". Other definitions are based on origin, making production in Japan a requisite for a work to be considered "anime". + +The etymology of the term anime is disputed. The English word "animation" is written in Japanese katakana as () and as (, ) in its shortened form. Some sources claim that the term is derived from the French term for animation ("cartoon", literally 'animated drawing'), but others believe this to be a myth derived from the popularity of anime in France in the late 1970s and 1980s. + +In English, anime—when used as a common noun—normally functions as a mass noun. (For example: "Do you watch anime?" or "How much anime have you collected?") As with a few other Japanese words, such as saké and Pokémon, English texts sometimes spell anime as animé (as in French), with an acute accent over the final e, to cue the reader to pronounce the letter, not to leave it silent as English orthography may suggest. Prior to the widespread use of anime, the term Japanimation, a portmanteau of Japan and animation, was prevalent throughout the 1970s and 1980s. In the mid-1980s, the term anime began to supplant Japanimation; in general, the latter term now only appears in period works where it is used to distinguish and identify Japanese animation. + +History + +Precursors + and kagee are considered precursors of Japanese animation. was common in the eleventh century. Traveling storytellers narrated legends and anecdotes while the was unrolled from the right to left in chronological order, as a moving panorama. Kagee was popular during the Edo period and originated from the shadows play of China. Magic lanterns from the Netherlands were also popular in the eighteenth century. The paper play called Kamishibai surged in the twelfth century and remained popular in the street theater until the 1930s. Puppets of the bunraku theater and ukiyo-e prints are considered ancestors of characters of most Japanese animations. Finally, mangas were a heavy inspiration for anime. Cartoonists Kitzawa Rakuten and Okamoto Ippei used film elements in their strips. + +Pioneers + +Animation in Japan began in the early 20th century, when filmmakers started to experiment with techniques pioneered in France, Germany, the United States, and Russia. A claim for the earliest Japanese animation is Katsudō Shashin (), a private work by an unknown creator. In 1917, the first professional and publicly displayed works began to appear; animators such as Ōten Shimokawa, Seitarō Kitayama, and Jun'ichi Kōuchi (considered the "fathers of anime") produced numerous films, the oldest surviving of which is Kōuchi's Namakura Gatana. Many early works were lost with the destruction of Shimokawa's warehouse in the 1923 Great Kantō earthquake. + +By the mid-1930s, animation was well-established in Japan as an alternative format to the live-action industry. It suffered competition from foreign producers, such as Disney, and many animators, including Noburō Ōfuji and Yasuji Murata, continued to work with cheaper cutout animation rather than cel animation. Other creators, including Kenzō Masaoka and Mitsuyo Seo, nevertheless made great strides in technique, benefiting from the patronage of the government, which employed animators to produce educational shorts and propaganda. In 1940, the government dissolved several artists' organizations to form the The first talkie anime was Chikara to Onna no Yo no Naka (1933), a short film produced by Masaoka. The first feature-length anime film was Momotaro: Sacred Sailors (1945), produced by Seo with a sponsorship from the Imperial Japanese Navy. The 1950s saw a proliferation of short, animated advertisements created for television. + +Modern era + +In the 1960s, manga artist and animator Osamu Tezuka adapted and simplified Disney animation techniques to reduce costs and limit frame counts in his productions. Originally intended as temporary measures to allow him to produce material on a tight schedule with an inexperienced staff, many of his limited animation practices came to define the medium's style. Three Tales (1960) was the first anime film broadcast on television; the first anime television series was Instant History (1961–64). An early and influential success was Astro Boy (1963–66), a television series directed by Tezuka based on his manga of the same name. Many animators at Tezuka's Mushi Production later established major anime studios (including Madhouse, Sunrise, and Pierrot). + +The 1970s saw growth in the popularity of manga, many of which were later animated. Tezuka's work—and that of other pioneers in the field—inspired characteristics and genres that remain fundamental elements of anime today. The giant robot genre (also known as "mecha"), for instance, took shape under Tezuka, developed into the super robot genre under Go Nagai and others, and was revolutionized at the end of the decade by Yoshiyuki Tomino, who developed the real robot genre. Robot anime series such as Gundam and Super Dimension Fortress Macross became instant classics in the 1980s, and the genre remained one of the most popular in the following decades. The bubble economy of the 1980s spurred a new era of high-budget and experimental anime films, including Nausicaä of the Valley of the Wind (1984), Royal Space Force: The Wings of Honnêamise (1987), and Akira (1988). + +Neon Genesis Evangelion (1995), a television series produced by Gainax and directed by Hideaki Anno, began another era of experimental anime titles, such as Ghost in the Shell (1995) and Cowboy Bebop (1998). In the 1990s, anime also began attracting greater interest in Western countries; major international successes include Sailor Moon and Dragon Ball Z, both of which were dubbed into more than a dozen languages worldwide. In 2003, Spirited Away, a Studio Ghibli feature film directed by Hayao Miyazaki, won the Academy Award for Best Animated Feature at the 75th Academy Awards. It later became the highest-grossing anime film, earning more than $355 million. Since the 2000s, an increased number of anime works have been adaptations of light novels and visual novels; successful examples include The Melancholy of Haruhi Suzumiya and Fate/stay night (both 2006). Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train became the highest-grossing Japanese film and one of the world's highest-grossing films of 2020. It also became the fastest grossing film in Japanese cinema, because in 10 days it made 10 billion yen ($95.3m; £72m). It beat the previous record of Spirited Away which took 25 days. + +Attributes + +Anime differs from other forms of animation by its art styles, methods of animation, its production, and its process. Visually, anime works exhibit a wide variety of art styles, differing between creators, artists, and studios. While no single art style predominates anime as a whole, they do share some similar attributes in terms of animation technique and character design. + +Anime is fundamentally characterized by the use of limited animation, flat expression, the suspension of time, its thematic range, the presence of historical figures, its complex narrative line and, above all, a peculiar drawing style, with characters characterized by large and oval eyes, with very defined lines, bright colors and reduced movement of the lips. + +Technique +Modern anime follows a typical animation production process, involving storyboarding, voice acting, character design, and cel production. Since the 1990s, animators have increasingly used computer animation to improve the efficiency of the production process. Early anime works were experimental, and consisted of images drawn on blackboards, stop motion animation of paper cutouts, and silhouette animation. Cel animation grew in popularity until it came to dominate the medium. In the 21st century, the use of other animation techniques is mostly limited to independent short films, including the stop motion puppet animation work produced by Tadahito Mochinaga, Kihachirō Kawamoto and Tomoyasu Murata. Computers were integrated into the animation process in the 1990s, with works such as Ghost in the Shell and Princess Mononoke mixing cel animation with computer-generated images. Fuji Film, a major cel production company, announced it would stop cel production, producing an industry panic to procure cel imports and hastening the switch to digital processes. + +Prior to the digital era, anime was produced with traditional animation methods using a pose to pose approach. The majority of mainstream anime uses fewer expressive key frames and more in-between animation. + +Japanese animation studios were pioneers of many limited animation techniques, and have given anime a distinct set of conventions. Unlike Disney animation, where the emphasis is on the movement, anime emphasizes the art quality and let limited animation techniques make up for the lack of time spent on movement. Such techniques are often used not only to meet deadlines but also as artistic devices. Anime scenes place emphasis on achieving three-dimensional views, and backgrounds are instrumental in creating the atmosphere of the work. The backgrounds are not always invented and are occasionally based on real locations, as exemplified in Howl's Moving Castle and The Melancholy of Haruhi Suzumiya. Oppliger stated that anime is one of the rare mediums where putting together an all-star cast usually comes out looking "tremendously impressive". + +The cinematic effects of anime differentiates itself from the stage plays found in American animation. Anime is cinematically shot as if by camera, including panning, zooming, distance and angle shots to more complex dynamic shots that would be difficult to produce in reality. In anime, the animation is produced before the voice acting, contrary to American animation which does the voice acting first. + +Characters + +The body proportions of human anime characters tend to accurately reflect the proportions of the human body in reality. The height of the head is considered by the artist as the base unit of proportion. Head heights can vary, but most anime characters are about seven to eight heads tall. Anime artists occasionally make deliberate modifications to body proportions to produce super deformed characters that feature a disproportionately small body compared to the head; many super deformed characters are two to four heads tall. Some anime works like Crayon Shin-chan completely disregard these proportions, in such a way that they resemble caricatured Western cartoons. + +A common anime character design convention is exaggerated eye size. The animation of characters with large eyes in anime can be traced back to Osamu Tezuka, who was deeply influenced by such early animation characters as Betty Boop, who was drawn with disproportionately large eyes. Tezuka is a central figure in anime and manga history, whose iconic art style and character designs allowed for the entire range of human emotions to be depicted solely through the eyes. The artist adds variable color shading to the eyes and particularly to the cornea to give them greater depth. Generally, a mixture of a light shade, the tone color, and a dark shade is used. Cultural anthropologist Rachel Thorn argues that Japanese animators and audiences do not perceive such stylized eyes as inherently more or less foreign. However, not all anime characters have large eyes. For example, the works of Hayao Miyazaki are known for having realistically proportioned eyes, as well as realistic hair colors on their characters. + +Hair in anime is often unnaturally lively and colorful or uniquely styled. The movement of hair in anime is exaggerated and "hair actions" is used to emphasize the action and emotions of characters for added visual effect. Poitras traces hairstyle color to cover illustrations on manga, where eye-catching artwork and colorful tones are attractive for children's manga. Despite being produced for a domestic market, anime features characters whose race or nationality is not always defined, and this is often a deliberate decision, such as in the Pokémon animated series. + +Anime and manga artists often draw from a common canon of iconic facial expression illustrations to denote particular moods and thoughts. These techniques are often different in form than their counterparts in Western animation, and they include a fixed iconography that is used as shorthand for certain emotions and moods. For example, a male character may develop a nosebleed when aroused. A variety of visual symbols are employed, including sweat drops to depict nervousness, visible blushing for embarrassment, or glowing eyes for an intense glare. Another recurring sight gag is the use of chibi (deformed, simplified character designs) figures to comedically punctuate emotions like confusion or embarrassment. + +Music + +The opening and credits sequences of most anime television series are accompanied by J-pop or J-rock songs, often by reputed bands—as written with the series in mind—but are also aimed at the general music market, therefore they often allude only vaguely or not at all, to the thematic settings or plot of the series. Also, they are often used as incidental music ("insert songs") in an episode, in order to highlight particularly important scenes. + +Future funk, a musical microgenre that evolved in the early 2010's from Vaporwave with a French house Euro disco influence, heavily uses anime visuals and samples along with Japanese City pop to build an aesthetic. + +Since the 2020's anime songs have experienced a rapid growth in global online popularity due to their widened availability on music streaming services like Spotify and promotion by fans and artists on social media. In 2023, the opening theme Idol by YOASOBI of the anime series Oshi no Ko topped the Billboard Global 200 Excl. U.S. charts with 45.7 million streams and 24,000 copies sold outside the U.S. “Idol” has become the first Japanese song and anime song to top the Billboard Global chart as well as taking the first spot on the Apple Music's Top 100: Global chart. + +Genres +Anime are often classified by target demographic, including , , , , and a diverse range of genres targeting an adult audience. Shoujo and shounen anime sometimes contain elements popular with children of both sexes in an attempt to gain crossover appeal. Adult anime may feature a slower pace or greater plot complexity that younger audiences may typically find unappealing, as well as adult themes and situations. A subset of adult anime works featuring pornographic elements are labeled "R18" in Japan, and are internationally known as hentai (originating from ). By contrast, some anime subgenres incorporate ecchi, sexual themes or undertones without depictions of sexual intercourse, as typified in the comedic or harem genres; due to its popularity among adolescent and adult anime enthusiasts, the inclusion of such elements is considered a form of fan service. Some genres explore homosexual romances, such as yaoi (male homosexuality) and yuri (female homosexuality). While often used in a pornographic context, the terms yaoi and yuri can also be used broadly in a wider context to describe or focus on the themes or the development of the relationships themselves. + +Anime's genre classification differs from other types of animation and does not lend itself to simple classification. Gilles Poitras compared the labeling of Gundam 0080 and its complex depiction of war as a "giant robot" anime akin to simply labeling War and Peace a "war novel". Science fiction is a major anime genre and includes important historical works like Tezuka's Astro Boy and Yokoyama's Tetsujin 28-go. A major subgenre of science fiction is mecha, with the Gundam metaseries being iconic. The diverse fantasy genre includes works based on Asian and Western traditions and folklore; examples include the Japanese feudal fairytale InuYasha, and the depiction of Scandinavian goddesses who move to Japan to maintain a computer called Yggdrasil in Ah! My Goddess. Genre crossing in anime is also prevalent, such as the blend of fantasy and comedy in Dragon Half, and the incorporation of slapstick humor in the crime anime film Castle of Cagliostro. Other subgenres found in anime include magical girl, harem, sports, martial arts, literary adaptations, medievalism, and war. + +Formats +Early anime works were made for theatrical viewing, and required played musical components before sound and vocal components were added to the production. In 1958, Nippon Television aired Mogura no Abanchūru ("Mole's Adventure"), both the first televised and first color anime to debut. It was not until the 1960s when the first televised series were broadcast and it has remained a popular medium since. Works released in a direct-to-video format are called "original video animation" (OVA) or "original animation video" (OAV); and are typically not released theatrically or televised prior to home media release. The emergence of the Internet has led some animators to distribute works online in a format called "original net animation" (ONA). + +The home distribution of anime releases was popularized in the 1980s with the VHS and LaserDisc formats. The VHS NTSC video format used in both Japan and the United States is credited with aiding the rising popularity of anime in the 1990s. The LaserDisc and VHS formats were transcended by the DVD format which offered the unique advantages; including multiple subtitling and dubbing tracks on the same disc. The DVD format also has its drawbacks in its usage of region coding; adopted by the industry to solve licensing, piracy and export problems and restricted region indicated on the DVD player. The Video CD (VCD) format was popular in Hong Kong and Taiwan, but became only a minor format in the United States that was closely associated with bootleg copies. + +A key characteristic of many anime television shows is serialization, where a continuous story arc stretches over multiple episodes or seasons. Traditional American television had an episodic format, with each episode typically consisting of a self-contained story. In contrast, anime shows such as Dragon Ball Z had a serialization format, where continuous story arcs stretch over multiple episodes or seasons, which distinguished them from traditional American television shows; serialization has since also become a common characteristic of American streaming television shows during the "Peak TV" era. + +Industry + +The animation industry consists of more than 430 production companies with some of the major studios including Toei Animation, Gainax, Madhouse, Gonzo, Sunrise, Bones, TMS Entertainment, Nippon Animation, P.A.Works, Studio Pierrot, Production I.G, Ufotable and Studio Ghibli. Many of the studios are organized into a trade association, The Association of Japanese Animations. There is also a labor union for workers in the industry, the Japanese Animation Creators Association. Studios will often work together to produce more complex and costly projects, as done with Studio Ghibli's Spirited Away. An anime episode can cost between US$100,000 and US$300,000 to produce. In 2001, animation accounted for 7% of the Japanese film market, above the 4.6% market share for live-action works. The popularity and success of anime is seen through the profitability of the DVD market, contributing nearly 70% of total sales. According to a 2016 article on Nikkei Asian Review, Japanese television stations have bought over worth of anime from production companies "over the past few years", compared with under from overseas. There has been a rise in sales of shows to television stations in Japan, caused by late night anime with adults as the target demographic. This type of anime is less popular outside Japan, being considered "more of a niche product". Spirited Away (2001) was the all-time highest-grossing film in Japan until overtaken by Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train in 2020. It was also the highest-grossing anime film worldwide until it was overtaken by Makoto Shinkai's 2016 film Your Name. Anime films represent a large part of the highest-grossing Japanese films yearly in Japan, with 6 out of the top 10 in 2014, in 2015 and also in 2016. + +Anime has to be licensed by companies in other countries in order to be legally released. While anime has been licensed by its Japanese owners for use outside Japan since at least the 1960s, the practice became well-established in the United States in the late 1970s to early 1980s, when such TV series as Gatchaman and Captain Harlock were licensed from their Japanese parent companies for distribution in the US market. The trend towards American distribution of anime continued into the 1980s with the licensing of titles such as Voltron and the 'creation' of new series such as Robotech through the use of source material from several original series. + +In the early 1990s, several companies began to experiment with the licensing of less children-oriented material. Some, such as A.D. Vision, and Central Park Media and its imprints, achieved fairly substantial commercial success and went on to become major players in the now very lucrative American anime market. Others, such as AnimEigo, achieved limited success. Many companies created directly by Japanese parent companies did not do as well, most releasing only one or two titles before completing their American operations. + +Licenses are expensive, often hundreds of thousands of dollars for one series and tens of thousands for one movie. The prices vary widely; for example, Jinki: Extend cost only $91,000 to license while Kurau Phantom Memory cost $960,000. Simulcast Internet streaming rights can be cheaper, with prices around $1,000–2,000 an episode, but can also be more expensive, with some series costing more than per episode. + +The anime market for the United States was worth approximately $2.74 billion in 2009. Dubbed animation began airing in the United States in 2000 on networks like The WB and Cartoon Network's Adult Swim. In 2005, this resulted in five of the top ten anime titles having previously aired on Cartoon Network. As a part of localization, some editing of cultural references may occur to better follow the references of the non-Japanese culture. The cost of English localization averages US$10,000 per episode. + +The industry has been subject to both praise and condemnation for fansubs, the addition of unlicensed and unauthorized subtitled translations of anime series or films. Fansubs, which were originally distributed on VHS bootlegged cassettes in the 1980s, have been freely available and disseminated online since the 1990s. Since this practice raises concerns for copyright and piracy issues, fansubbers tend to adhere to an unwritten moral code to destroy or no longer distribute an anime once an official translated or subtitled version becomes licensed. They also try to encourage viewers to buy an official copy of the release once it comes out in English, although fansubs typically continue to circulate through file-sharing networks. Even so, the laid back regulations of the Japanese animation industry tend to overlook these issues, allowing it to grow underground and thus increasing its popularity until there is a demand for official high-quality releases for animation companies. This has led to an increase in global popularity of Japanese animations, reaching $40 million in sales in 2004. + +Since the 2010s anime has become a global multibillion industry setting a sales record in 2017 of ¥2.15 trillion ($19.8 billion), driven largely by demand from overseas audiences. In 2019, Japan's anime industry was valued at $24 billion a year with 48% of that revenue coming from overseas (which is now its largest industry sector). By 2025 the anime industry is expected to reach a value of $30 billion with over 60% of that revenue coming from +overseas. + +Markets +Japan External Trade Organization (JETRO) valued the domestic anime market in Japan at (), including from licensed products, in 2005. JETRO reported sales of overseas anime exports in 2004 to be (). JETRO valued the anime market in the United States at (), including in home video sales and over from licensed products, in 2005. JETRO projected in 2005 that the worldwide anime market, including sales of licensed products, would grow to (). The anime market in China was valued at in 2017, and is projected to reach by 2020. The global anime market size was valued at $26.055 billion in 2021 with 29% of the revenue coming from merchandise. It is expected that the global anime market will reach a value of $47.14 billion by 2028. By 2030 the global anime market is expected to reach a value of $48.3 Billion with the largest contributors to this growth being North America, Europe, China and The Middle East. +In 2019, the annual overseas exports of Japanese animation exceeded $10 billion for the first time in history. + +Awards +The anime industry has several annual awards that honor the year's best works. Major annual awards in Japan include the Ōfuji Noburō Award, the Mainichi Film Award for Best Animation Film, the Animation Kobe Awards, the Japan Media Arts Festival animation awards, the Seiyu Awards for voice actors, the Tokyo Anime Award and the Japan Academy Prize for Animation of the Year. In the United States, anime films compete in the Crunchyroll Anime Awards. There were also the American Anime Awards, which were designed to recognize excellence in anime titles nominated by the industry, and were held only once in 2006. Anime productions have also been nominated and won awards not exclusively for anime, like the Academy Award for Best Animated Feature or the Golden Bear. + +Working conditions +In recent years, the anime industry has been accused by both Japanese and foreign media of underpaying and overworking its animators. In response the Japanese Prime Minister Fumio Kishida promised to improve the working conditions and salary of all animators and creators working in the industry. A few anime studios such as MAPPA have taken actions to improve the working conditions of their employees. There has also been a slight increase in production costs and animator pays during the COVID-19 pandemic. On April 27, 2023, Nippon Anime Film Culture Association (NAFCA) was officially founded. The association aims to solve problems in the industry, including the improvement of conditions of the workers. + +Globalization and cultural impact + +Anime has become commercially profitable in Western countries, as demonstrated by early commercially successful Western adaptations of anime, such as Astro Boy and Speed Racer. Early American adaptions in the 1960s made Japan expand into the continental European market, first with productions aimed at European and Japanese children, such as Heidi, Vicky the Viking and Barbapapa, which aired in various countries. Italy, Spain, and France grew a particular interest in Japan's output, due to its cheap selling price and productive output. As of 2014, Italy imported the most anime outside Japan. Anime and manga were introduced to France in the late 1970s and became massively popular in spite of a moral panic led by French politicians in the 1980s and 1990s. These mass imports influenced anime popularity in South American, Arabic and German markets. + +The beginning of 1980 saw the introduction of Japanese anime series into the American culture. In the 1990s, Japanese animation slowly gained popularity in America. Media companies such as Viz and Mixx began publishing and releasing animation into the American market. The 1988 film Akira is largely credited with popularizing anime in the Western world during the early 1990s, before anime was further popularized by television shows such as Pokémon and Dragon Ball Z in the late 1990s. By 1997, Japanese anime was the fastest-growing genre in the American video industry. The growth of the Internet later provided international audiences with an easy way to access Japanese content. Early on, online piracy played a major role in this, through over time many legal alternatives appeared. Since the 2010s various streaming services have become increasingly involved in the production and licensing of anime for the international markets. This is especially the case with net services such as Netflix and Crunchyroll which have large catalogs in Western countries, although as of 2020 anime fans in many developing non-Western countries, such as India and Philippines, have fewer options for obtaining access to legal content, and therefore still turn to online piracy. However beginning with the 2020s anime has been experiencing yet another boom in global popularity and demand due to the COVID-19 pandemic and streaming services like Netflix, Amazon Prime Video, HBO Max, Disney+, Hulu and anime-only services like Crunchyroll and Hidive, increasing the international availability of the amount of new licensed anime shows as well as the size of their catalogs. +Netflix reported that, between October 2019 and September 2020, more than member households worldwide had watched at least one anime title on the platform. Anime titles appeared on the streaming platform's top-ten lists in almost 100 countries within the one-year period. +As of 2021, anime series are the most demanded foreign-language television shows in the United States accounting for 30.5% of the market share. (In comparison, Spanish-language and Korean-language shows account for 21% and 11% of the market share, respectively.) In 2021 more than half of Netflix's global members watched anime. +In 2022, the anime series Attack on Titan won the award of "Most In-Demand TV Series in the World 2021" in the Global TV Demand Awards. Attack on Titan became the first ever non-English language series to earn the title of "World's Most In-Demand TV Show", previously held by only The Walking Dead and Game of Thrones. + +Rising interest in anime as well as Japanese video games has led to an increase of university students in the United Kingdom wanting to get a degree in the Japanese language. The word anime alongside other Japanese pop cultural terms like shonen and shojo have been added to the Oxford English Dictionary. + +Various anime and manga series have influenced Hollywood in the making of numerous famous movies and characters. Hollywood itself has produced live-action adaptations of various anime series such as Ghost in the Shell, Death Note, Dragon Ball Evolution and Cowboy Bebop. However most of these adaptations have been reviewed negatively by both the critics and the audience and have become box-office flops. The main reasons for the unsuccessfulness of Hollywood's adaptions of anime being the often change of plot and characters from the original source material and the limited capabilities a live-action movie or series can do in comparison to an animated counterpart. One particular exception however is Alita: Battle Angel, which has become a moderate commercial success, receiving generally positive reviews from both the critics and the audience for its visual effects and following the source material. The movie grossed $404 million worldwide, making it director Robert Rodriguez's highest-grossing film. + +Anime and manga alongside many other parts of Japanese pop culture have helped Japan to gain a positive worldwide image and improve its relations with other countries. In 2015, during remarks welcoming Japanese Prime Minister Shinzo Abe to the White House, President Barack Obama thanked Japan for its cultural contributions to the United States by saying: + +In July 2020, after the approval of a Chilean government project in which citizens of Chile would be allowed to withdraw up to 10% of their privately held retirement savings, journalist Pamela Jiles celebrated by running through Congress with her arms spread out behind her, imitating the move of many characters of the anime and manga series Naruto. In April 2021, Peruvian politicians Jorge Hugo Romero of the PPC and Milagros Juárez of the UPP cosplayed as anime characters to get the otaku vote. + +In April 2023, the Japan Business Federation laid out a proposal aiming to spur the economic growth of Japan by further promoting the contents industry abroad, primarily anime, manga and video games, for measures to invite industry experts from abroad to come to Japan to work, and to link with the tourism sector to help foreign fans of manga and anime visit sites across the country associated with particular manga stories. The federation seeks on quadrupling the sales of Japanese content in overseas markets within the upcoming 10 years. + +A 2018 survey conducted in 20 countries and territories using a sample consisting of 6,600 respondents held by Dentsu revealed that 34% of all surveyed people found excellency in anime and manga more than other Japanese cultural or technological aspects which makes this mass Japanese media the 3rd most liked "Japanese thing", below Japanese cuisine (34.6%) and Japanese robotics (35.1%). The advertisement company views anime as a profitable tool for marketing campaigns in foreign countries due to its popularity and high reception. +Anime plays a role in driving tourism to Japan. In surveys held by Statista between 2019 and 2020, 24.2% of tourists from the United States, 7.7% of tourists from China and 6.1% of tourists from South Korea said they were motivated to visit Japan because of Japanese popular culture. In a 2021 survey held by Crunchyroll market research, 94% of Gen-Z's and 73% of the general population said that they are familiar with anime. + +Fan response + + +Anime clubs gave rise to anime conventions in the 1990s with the "anime boom", a period marked by anime's increased global popularity. These conventions are dedicated to anime and manga and include elements like cosplay contests and industry talk panels. Cosplay, a portmanteau of "costume play", is not unique to anime and has become popular in contests and masquerades at anime conventions. Japanese culture and words have entered English usage through the popularity of the medium, including otaku, an unflattering Japanese term commonly used in English to denote an obsessive fan of anime and/or manga. Another word that has arisen describing obsessive fans in the United States is wapanese meaning 'white individuals who want to be Japanese', or later known as weeaboo or weeb, individuals who demonstrate an obsession with Japanese anime subculture, a term that originated from abusive content posted on the website 4chan.org. While originally derogatory, the terms "Otaku" and "Weeb" have been reappropriated by the anime fandom overtime and today are used by some fans to refer to themselves in a comedic and more positive way. +Anime enthusiasts have produced fan fiction and fan art, including computer wallpapers and anime music videos (AMVs). + +Many fans will visit sites depicted in anime, games, manga and other forms of otaku culture, this behavior is known as "Anime pilgrimage". + +As of the 2020s, many anime fans and followers use social media platforms and other sites like YouTube, Twitch, Fandom, Facebook, Reddit, Discord, Tumblr, 4chan, Tiktok and Twitter with online communities and databases such as IMDb, MyAnimeList to discuss anime, manga and track their progress watching respective series as well as using news outlets such as Anime News Network. + +Due to anime's increased popularity in recent years, a large number of celebrities such as Elon Musk, BTS and Ariana Grande have come out as anime fans. + +Anime style + +One of the key points that made anime different from a handful of Western cartoons is the potential for visceral content. Once the expectation that the aspects of visual intrigue or animation are just for children is put aside, the audience can realize that themes involving violence, suffering, sexuality, pain, and death can all be storytelling elements utilized in anime just as much as other media. + +However, as anime itself became increasingly popular, its styling has been inevitably the subject of both satire and serious creative productions. South Parks "Chinpokomon" and "Good Times with Weapons" episodes, Adult Swim's Perfect Hair Forever, and Nickelodeon's Kappa Mikey are examples of Western satirical depictions of Japanese culture and anime, but anime tropes have also been satirized by some anime such as KonoSuba. + +Traditionally only Japanese works have been considered anime, but some works have sparked debate about blurring the lines between anime and cartoons, such as the American anime-style productions Avatar: The Last Airbender and Avatar: The Legend of Korra. These anime-styled works have become defined as anime-influenced animation, in an attempt to classify all anime styled works of non-Japanese origin. Some creators of these works cite anime as a source of inspiration, for example the French production team for Ōban Star-Racers that moved to Tokyo to collaborate with a Japanese production team. When anime is defined as a "style" rather than as a national product, it leaves open the possibility of anime being produced in other countries, but this has been contentious amongst fans, with John Oppliger stating, "The insistence on referring to original American art as Japanese "anime" or "manga" robs the work of its cultural identity." + +A U.A.E.-Filipino produced TV series called Torkaizer is dubbed as the "Middle East's First Anime Show", and is currently in production and looking for funding. Netflix has produced multiple anime series in collaboration with Japanese animation studios, and in doing so, has offered a more accessible channel for distribution to Western markets. + +The web-based series RWBY, produced by Texas-based company Rooster Teeth, is produced using an anime art style, and the series has been described as "anime" by multiple sources. For example, Adweek, in the headline to one of its articles, described the series as "American-made anime", and in another headline, The Huffington Post described it as simply "anime", without referencing its country of origin. In 2013, Monty Oum, the creator of RWBY, said "Some believe just like Scotch needs to be made in Scotland, an American company can't make anime. I think that's a narrow way of seeing it. Anime is an art form, and to say only one country can make this art is wrong." RWBY has been released in Japan with a Japanese language dub; the CEO of Rooster Teeth, Matt Hullum, commented "This is the first time any American-made anime has been marketed to Japan. It definitely usually works the other way around, and we're really pleased about that." + +Media franchises + +In Japanese culture and entertainment, media mix is a strategy to disperse content across multiple representations: different broadcast media, gaming technologies, cell phones, toys, amusement parks, and other methods. It is the Japanese term for a transmedia franchise. The term gained its circulation in late 1980s, but the origins of the strategy can be traced back to the 1960s with the proliferation of anime, with its interconnection of media and commodity goods. + +A number of anime and manga media franchises such as Demon Slayer: Kimetsu no Yaiba, Dragon Ball and Gundam have gained considerable global popularity, and are among the world's highest-grossing media franchises. Pokémon in particular is estimated to be the highest-grossing media franchise of all time. + +See also + + Animation director + Aeni + Chinese animation + Cinema of Japan + Cool Japan + Culture of Japan + History of anime + Japanophilia + Japanese language + Japanese popular culture + Lists of anime + Mass media in Japan + Manga + Mechademia + Otaku + Television in Japan + Vtuber + Voice acting in Japan + +Notes + +References + +Sources + +External links + + + + +1917 introductions +Anime and manga terminology +Japanese inventions +Asterism may refer to: + + Asterism (astronomy), a pattern of stars + Asterism (gemology), an optical phenomenon in gemstones + Asterism (typography), (⁂) a moderately rare typographical symbol denoting a break in passages + +See also + + + Aster (disambiguation) + Asterisk (disambiguation) +Ankara ( , ; ), historically known as Ancyra and Angora, is the capital of Turkey. Located in the central part of Anatolia, the city has a population of 5.1 million in its urban center and 5.7 million in Ankara Province, making it Turkey's second-largest city after Istanbul, but first by the urban area (2,767 km2). + +Serving as the capital of the ancient Celtic state of Galatia (280–64 BC), and later of the Roman province with the same name (25 BC–7th century), the city is very old, with various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393 – late 15th century) and then the Angora Eyalet (1827–1864) and the Angora Vilayet (1867–1922). The historical center of Ankara is a rocky hill rising over the left bank of the Ankara River, a tributary of the Sakarya River. The hill remains crowned by the ruins of Ankara Castle. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture throughout the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the . + +On 23 April 1920, the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the establishment of the Republic on 29 October 1923, succeeding in this role as the former Turkish capital Istanbul following the fall of the Ottoman Empire. The government is a prominent employer, but Ankara is also an important commercial and industrial city located at the center of Turkey's road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat (the source of mohair), and the Angora cat. The area is also known for its pears, honey and Muscat grapes. Although situated in one of the driest regions of Turkey and surrounded mostly by steppe vegetation (except for the forested areas on the southern periphery), Ankara can be considered a green city in terms of green areas per inhabitant, at per head. + +Etymology + +The orthography of the name Ankara has varied over the ages. It has been identified with the Hittite cult center Ankuwaš, although this remains a matter of debate. In classical antiquity and during the medieval period, the city was known as Ánkyra (,  "anchor") in Greek and Ancyra in Latin; the Galatian Celtic name was probably a similar variant. Following its annexation by the Seljuk Turks in 1073, the city became known in many European languages as Angora; it was also known in Ottoman Turkish as Engürü. The form "Angora" is preserved in the names of breeds of many different kinds of animals, and in the names of several locations in the US (see Angora). + +History + +The region's history can be traced back to the Bronze Age Hattic civilization, which was succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, and later by the Lydians, Persians, Greeks, Galatians, Romans, Byzantines, and Turks (the Seljuk Sultanate of Rûm, the Ottoman Empire and finally republican Turkey). + +Ancient history + +The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was gradually absorbed c. 2000 – 1700 BC by the Indo-European Hittites. The city grew significantly in size and importance under the Phrygians starting around 1000 BC, and experienced a large expansion following the mass migration from Gordion, (the capital of Phrygia), after an earthquake which severely damaged that city around that time. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was actually far older, which accords with present archeological knowledge. + +Phrygian rule was succeeded first by Lydian and later by Persian rule, though the strongly Phrygian character of the peasantry remained, as evidenced by the gravestones of the much later Roman period. Persian sovereignty lasted until the Persians' defeat at the hands of Alexander the Great who conquered the city in 333 BC. Alexander came from Gordion to Ankara and stayed in the city for a short period. After his death at Babylon in 323 BC and the subsequent division of his empire among his generals, Ankara, and its environs fell into the share of Antigonus. + +Another important expansion took place under the Greeks of Pontos who came there around 300 BC and developed the city as a trading center for the commerce of goods between the Black Sea ports and Crimea to the north; Assyria, Cyprus, and Lebanon to the south; and Georgia, Armenia and Persia to the east. By that time the city also took its name Ἄγκυρα (Ánkyra, meaning anchor in Greek) which, in slightly modified form, provides the modern name of Ankara. + +Celtic history + +In 278 BC, the city, along with the rest of central Anatolia, was occupied by a Celtic group, the Galatians, who were the first to make Ankara one of their main tribal centers, the headquarters of the Tectosages tribe. Other centers were Pessinus, today's Ballıhisar, for the Trocmi tribe, and Tavium, to the east of Ankara, for the Tolistobogii tribe. The city was then known as Ancyra. The Celtic element was probably relatively small in numbers; a warrior aristocracy which ruled over Phrygian-speaking peasants. However, the Celtic language continued to be spoken in Galatia for many centuries. At the end of the 4th century, St. Jerome, a native of Dalmatia, observed that the language spoken around Ankara was very similar to that being spoken in the northwest of the Roman world near Trier. + +Roman history + +The city was subsequently passed under the control of the Roman Empire. In 25 BC, Emperor Augustus raised it to the status of a polis and made it the capital city of the Roman province of Galatia. Ankara is famous for the Monumentum Ancyranum (Temple of Augustus and Rome) which contains the official record of the Acts of Augustus, known as the Res Gestae Divi Augusti, an inscription cut in marble on the walls of this temple. The ruins of Ancyra still furnish today valuable bas-reliefs, inscriptions and other architectural fragments. Two other Galatian tribal centers, Tavium near Yozgat, and Pessinus (Balhisar) to the west, near Sivrihisar, continued to be reasonably important settlements in the Roman period, but it was Ancyra that grew into a grand metropolis. + +An estimated 200,000 people lived in Ancyra in good times during the Roman Empire, a far greater number than was to be the case from after the fall of the Roman Empire until the early 20th century. The small Ankara River ran through the center of the Roman town. It has now been covered and diverted, but it formed the northern boundary of the old town during the Roman, Byzantine and Ottoman periods. Çankaya, the rim of the majestic hill to the south of the present city center, stood well outside the Roman city, but may have been a summer resort. In the 19th century, the remains of at least one Roman villa or large house were still standing not far from where the Çankaya Presidential Residence stands today. To the west, the Roman city extended until the area of the Gençlik Park and Railway Station, while on the southern side of the hill, it may have extended downwards as far as the site presently occupied by Hacettepe University. It was thus a sizeable city by any standards and much larger than the Roman towns of Gaul or Britannia. + +Ancyra's importance rested on the fact that it was the junction point where the roads in northern Anatolia running north–south and east–west intersected, giving it major strategic importance for Rome's eastern frontier. The great imperial road running east passed through Ankara and a succession of emperors and their armies came this way. They were not the only ones to use the Roman highway network, which was equally convenient for invaders. In the second half of the 3rd century, Ancyra was invaded in rapid succession by the Goths coming from the west (who rode far into the heart of Cappadocia, taking slaves and pillaging) and later by the Arabs. For about a decade, the town was one of the western outposts of one of Palmyrean empress Zenobia in the Syrian Desert, who took advantage of a period of weakness and disorder in the Roman Empire to set up a short-lived state of her own. + +The town was reincorporated into the Roman Empire under Emperor Aurelian in 272. The tetrarchy, a system of multiple (up to four) emperors introduced by Diocletian (284–305), seems to have engaged in a substantial program of rebuilding and of road construction from Ancyra westwards to Germe and Dorylaeum (now Eskişehir). + +In its heyday, Roman Ancyra was a large market and trading center but it also functioned as a major administrative capital, where a high official ruled from the city's Praetorium, a large administrative palace or office. During the 3rd century, life in Ancyra, as in other Anatolian towns, seems to have become somewhat militarized in response to the invasions and instability of the town. + +Byzantine history +The city is well known during the 4th century as a center of Christian activity (see also below), due to frequent imperial visits, and through the letters of the pagan scholar Libanius. Bishop Marcellus of Ancyra and Basil of Ancyra were active in the theological controversies of their day, and the city was the site of no fewer than three church synods in 314, 358 and 375, the latter two in favor of Arianism. + +The city was visited by Emperor Constans I (r. 337–350) in 347 and 350, Julian (r. 361–363) during his Persian campaign in 362, and Julian's successor Jovian (r. 363–364) in winter 363/364 (he entered his consulship while in the city). After Jovian's death soon after, Valentinian I (r. 364–375) was acclaimed emperor at Ancyra, and in the next year his brother Valens (r. 364–378) used Ancyra as his base against the usurper Procopius. When the province of Galatia was divided sometime in 396/99, Ancyra remained the civil capital of Galatia I, as well as its ecclesiastical center (metropolitan see). Emperor Arcadius (r. 383–408) frequently used the city as his summer residence, and some information about the ecclesiastical affairs of the city during the early 5th century is found in the works of Palladius of Galatia and Nilus of Ancyra. + +In 479, the rebel Marcian attacked the city, without being able to capture it. In 610/11, Comentiolus, brother of Emperor Phocas (r. 602–610), launched his own unsuccessful rebellion in the city against Heraclius (r. 610–641). Ten years later, in 620 or more likely 622, it was captured by the Sassanid Persians during the Byzantine–Sassanid War of 602–628. Although the city returned to Byzantine hands after the end of the war, the Persian presence left traces in the city's archeology, and likely began the process of its transformation from a late antique city to a medieval fortified settlement. + +In 654, the city, also known in Arabic sources as Qalat as-Salasil ("fortress of the chains"), was captured for the first time by the Arabs of the Rashidun Caliphate, under Muawiyah, the future founder of the Umayyad Caliphate. At about the same time, the themes were established in Anatolia, and Ancyra became capital of the Opsician Theme, which was the largest and most important theme until it was split up under Emperor Constantine V (r. 741–775); Ancyra then became the capital of the new Bucellarian Theme. The city was captured at least temporarily by the Umayyad prince Maslama ibn Hisham in 739/40, the last of the Umayyads' territorial gains from the Byzantine Empire. Ancyra was attacked without success by Abbasid forces in 776 and in 798/99. In 805, Emperor Nikephoros I (r. 802–811) strengthened its fortifications, a fact which probably saved it from sack during the large-scale invasion of Anatolia by Caliph Harun al-Rashid in the next year. Arab sources report that Harun and his successor al-Ma'mun (r. 813–833) took the city, but this information is later invention. In 838, however, during the Amorium campaign, the armies of Caliph al-Mu'tasim (r. 833–842) converged and met at the city; abandoned by its inhabitants, Ancara was razed to the ground, before the Arab armies went on to besiege and destroy Amorium reaching as far as Smyrna. In 859, Emperor Michael III (r. 842–867) came to the city during a campaign against the Arabs, and ordered its fortifications restored. In 872, the city was menaced, but not taken, by the Paulicians under Chrysocheir. The last Arab raid to reach the city was undertaken in 931, by the Abbasid governor of Tarsus, Thamal al-Dulafi, but the city again was not captured. + +Ecclesiastical history + +Early Christian martyrs of Ancyra, about whom little is known, included Proklos and Hilarios who were natives of the otherwise unknown nearby village of Kallippi, and suffered repression under the emperor Trajan (98–117). In the 280s we hear of Philumenos, a Christian corn merchant from southern Anatolia, being captured and martyred in Ankara, and Eustathius. + +As in other Roman towns, the reign of Diocletian marked the culmination of the persecution of the Christians. In 303, Ancyra was one of the towns where the co-emperors Diocletian and his deputy Galerius launched their anti-Christian persecution. In Ancyra, their first target was the 38-year-old Bishop of the town, whose name was Clement. Clement's life describes how he was taken to Rome, then sent back, and forced to undergo many interrogations and hardship before he, and his brother, and various companions were put to death. The remains of the church of St. Clement can be found today in a building just off Işıklar Caddesi in the Ulus district. Quite possibly this marks the site where Clement was originally buried. Four years later, a doctor of the town named Plato and his brother Antiochus also became celebrated martyrs under Galerius. Theodotus of Ancyra is also venerated as a saint. + +However, the persecution proved unsuccessful and in 314 Ancyra was the center of an important council of the early church; its 25 disciplinary canons constitute one of the most important documents in the early history of the administration of the Sacrament of Penance. The synod also considered ecclesiastical policy for the reconstruction of the Christian Church after the persecutions, and in particular the treatment of lapsi—Christians who had given in to forced paganism (sacrifices) to avoid martyrdom during these persecutions. + +Though paganism was probably tottering in Ancyra in Clement's day, it may still have been the majority religion. Twenty years later, Christianity and monotheism had taken its place. Ancyra quickly turned into a Christian city, with a life dominated by monks and priests and theological disputes. The town council or senate gave way to the bishop as the main local figurehead. During the middle of the 4th century, Ancyra was involved in the complex theological disputes over the nature of Christ, and a form of Arianism seems to have originated there. + +In 362–363, Emperor Julian passed through Ancyra on his way to an ill-fated campaign against the Persians, and according to Christian sources, engaged in a persecution of various holy men. The stone base for a statue, with an inscription describing Julian as "Lord of the whole world from the British Ocean to the barbarian nations", can still be seen, built into the eastern side of the inner circuit of the walls of Ankara Castle. The Column of Julian which was erected in honor of the emperor's visit to the city in 362 still stands today. In 375, Arian bishops met at Ancyra and deposed several bishops, among them St. Gregory of Nyssa. + +In the late 4th century, Ancyra became something of an imperial holiday resort. After Constantinople became the East Roman capital, emperors in the 4th and 5th centuries would retire from the humid summer weather on the Bosporus to the drier mountain atmosphere of Ancyra. Theodosius II (408–450) kept his court in Ancyra in the summers. Laws issued in Ancyra testify to the time they spent there. + +The Metropolis of Ancyra continued to be a residential see of the Eastern Orthodox Church until the 20th century, with about 40,000 faithful, mostly Turkish-speaking, but that situation ended as a result of the 1923 Convention Concerning the Exchange of Greek and Turkish Populations. The earlier Armenian genocide put an end to the residential eparchy of Ancyra of the Armenian Catholic Church, which had been established in 1850. It is also a titular metropolis of the Ecumenical Patriarchate of Constantinople. + +Both the Ancient Byzantine Metropolitan archbishopric and the 'modern' Armenian eparchy are now listed by the Catholic Church as titular sees, with separate apostolic successions. + +Seljuk and Ottoman history + +After the Battle of Manzikert in 1071, the Seljuk Turks overran much of Anatolia. By 1073, the Turkish settlers had reached the vicinity of Ancyra, and the city was captured shortly after, at the latest by the time of the rebellion of Nikephoros Melissenos in 1081. In 1101, when the Crusade under Raymond IV of Toulouse arrived, the city had been under Danishmend control for some time. The Crusaders captured the city, and handed it over to the Byzantine emperor Alexios I Komnenos (r. 1081–1118). Byzantine rule did not last long, and the city was captured by the Seljuk Sultanate of Rum at some unknown point; in 1127, it returned to Danishmend control until 1143, when the Seljuks of Rum retook it. + +After the Battle of Köse Dağ in 1243, in which the Mongols defeated the Seljuks, most of Anatolia became part of the dominion of the Mongols. Taking advantage of Seljuk decline, a semi-religious cast of craftsmen and trade people named Ahiler chose Angora as their independent city-state in 1290. Orhan, the second Bey of the Ottoman Empire, captured the city in 1356. Timur defeated Bayezid I at the Battle of Ankara in 1402 and took the city, but in 1403 Angora was again under Ottoman control. + +The Levant Company maintained a factory in the town from 1639 to 1768. In the 19th century, its population was estimated at 20,000 to 60,000. It was sacked by Egyptians under Ibrahim Pasha in 1832. + +From 1867 to 1922, the city served as the capital of the Angora Vilayet, which included most of ancient Galatia. + +Prior to World War I, the town had a British consulate and a population of around 28,000, roughly of whom were Christian. + +Turkish republican capital + +Following the Ottoman defeat in World War I, the Ottoman capital Constantinople (modern Istanbul) and much of Anatolia was occupied by the Allies, who planned to share these lands between Armenia, France, Greece, Italy and the United Kingdom, leaving for the Turks the core piece of land in central Anatolia. In response, the leader of the Turkish nationalist movement, Mustafa Kemal Atatürk, established the headquarters of his resistance movement in Angora in 1920. After the Turkish War of Independence was won and the Treaty of Sèvres was superseded by the Treaty of Lausanne (1923), the Turkish nationalists replaced the Ottoman Empire with the Republic of Turkey on 29 October 1923. A few days earlier, Angora had officially replaced Constantinople as the new Turkish capital city, on 13 October 1923, and Republican officials declared that the city's name is Ankara. + +After Ankara became the capital of the newly founded Republic of Turkey, new development divided the city into an old section, called Ulus, and a new section, called Yenişehir. Ancient buildings reflecting Roman, Byzantine, and Ottoman history and narrow winding streets mark the old section. The new section, now centered on Kızılay Square, has the trappings of a more modern city: wide streets, hotels, theaters, shopping malls, and high-rises. + +Government offices and foreign embassies are also located in the new section. Ankara has experienced a phenomenal growth since it was made Turkey's capital in 1923, when it was "a small town of no importance". In 1924, the year after the government had moved there, Ankara had about 35,000 residents. By 1927 there were 44,553 residents and by 1950 the population had grown to 286,781. After 1930, the city officially became known in Western languages as Ankara. By the late 1930s, the English name "Angora" was no longer in popular use. + +Ankara continued to grow rapidly during the latter half of the 20th century and eventually outranked Izmir as Turkey's second-largest city, after Istanbul. Ankara's urban population reached 4,587,558 in 2014, while the population of Ankara Province reached 5,150,072 in 2015. + +The Presidential Palace of Turkey is situated in Ankara. This building serves as the main residence of the president. + +Geography + +Geographically, Ankara is located in the middle of the Kızılırmak and Sakarya rivers, and the Sakarya River forms its border with Eskişehir in the west. Ankara shares its borders with Bolu and Çankırı in the north; Konya in the south and Kırıkkale in the east. + +Ankara and its province are located in the Central Anatolia Region of Turkey. The Çubuk Brook flows through the city center of Ankara. It is connected in the western suburbs of the city to the Ankara River, which is a tributary of the Sakarya River. + +Climate + +Ankara has a cold semi-arid climate (Köppen climate classification: BSk). Under the Trewartha climate classification, Ankara has a temperate humid continental climate (Dc). Due to its elevation and inland location, Ankara has cold and snowy winters, and hot and dry summers. Rainfall occurs mostly during the spring and autumn. The city lies in USDA Hardiness zone 7b, and its annual average precipitation is fairly low at , nevertheless precipitation can be observed throughout the year. Monthly mean temperatures range from in January to in July, with an annual mean of . + +Demographics + +Ankara had a population of 75,000 in 1927. As of 2019, the population of the Ankara Province was 5,639,076. When Ankara became the capital of the Republic of Turkey in 1923, it was designated as a planned city for 500,000 future inhabitants. During the 1920s, 1930s and 1940s, the city grew in a planned and orderly pace. However, from the 1950s onward, the city grew much faster than envisioned, because unemployment and poverty forced people to migrate from the countryside into the city in order to seek a better standard of living. As a result, many illegal houses called gecekondu were built around the city, causing the unplanned and uncontrolled urban landscape of Ankara, as not enough planned housing could be built fast enough. Although precariously built, the vast majority of them have electricity, running water and modern household amenities. + +Nevertheless, many of these gecekondus have been replaced by huge public housing projects in the form of tower blocks such as Elvankent, Eryaman and Güzelkent; and also as mass housing compounds for military and civil service accommodation. Although many gecekondus still remain, they too are gradually being replaced by mass housing compounds, as empty land plots in the city of Ankara for new construction projects are becoming impossible to find. + +Çorum and Yozgat, which are located in Central Anatolia and whose population is decreasing, are the provinces with the highest net migration to Ankara. About one third of the Central Anatolia population of 15,608,868 people resides in Ankara. + +The literacy rate in the whole province for people who are 15 years old or older is 98.18% according to 2020 TÜİK data. Ankara Province also has the highest percentage of tertiary education graduates in Turkey with 29.08% of the population having either an undergraduate, master's or doctor's degree. + +Economy and infrastructure + +Ankara has long been a productive agricultural region in Anatolia. In the Ottoman period, Ankara was well known for producing grain, cotton, and fruits. + +The city has exported mohair (from the Angora goat) and Angora wool (from the Angora rabbit) internationally for centuries. In the 19th century, the city also exported substantial amounts of goat and cat skins, gum, wax, honey, berries, and madder root. It was connected to Istanbul by railway before the First World War, continuing to export mohair, wool, berries, and grain. + +The Central Anatolia Region is one of the primary locations of grape and wine production in Turkey, and Ankara is particularly famous for its Kalecik Karası and Muscat grapes; and its Kavaklıdere wine, which is produced in the Kavaklıdere neighborhood within the Çankaya district of the city. Ankara is also famous for its pears. Another renowned natural product of Ankara is its indigenous type of honey (Ankara Balı) which is known for its light color and is mostly produced by the Atatürk Forest Farm and Zoo in the Gazi district, and by other facilities in the Elmadağ, Çubuk and Beypazarı districts. Çubuk-1 and Çubuk-2 dams on the Çubuk Brook in Ankara were among the first dams constructed in the Turkish Republic. + +Ankara is the center of the state-owned and private Turkish defence and aerospace companies, where the industrial plants and headquarters of the Turkish Aerospace Industries, MKE, ASELSAN, HAVELSAN, ROKETSAN, FNSS, Nurol Makina, and numerous other firms are located. Exports to foreign countries from these defense and aerospace firms have steadily increased in the past decades. The IDEF in Ankara is one of the largest international expositions of the global arms industry. A number of the global automotive companies also have production facilities in Ankara, such as the German bus and truck manufacturer MAN SE. Ankara hosts the OSTIM Industrial Zone, Turkey's largest industrial park. + +A large percentage of the complicated employment in Ankara is provided by the state institutions; such as the ministries, subministries, and other administrative bodies of the Turkish government. There are also many foreign citizens working as diplomats or clerks in the embassies of their respective countries. + +Transportation + +The Electricity, Gas, Bus General Directorate (EGO) operates the Ankara Metro and other forms of public transportation. Ankara is served by a suburban rail named Ankaray (A1) and three subway lines (M1, M2, M3) of the Ankara Metro with about 300,000 total daily commuters, while an additional subway line (M4) is under construction. A long gondola lift with four stations connects the district of Şentepe to the Yenimahalle metro station. + +The Ankara Central Station is a major rail hub in Turkey. The Turkish State Railways operates passenger train service from Ankara to other major cities, such as: Istanbul, Eskişehir, Balıkesir, Kütahya, İzmir, Kayseri, Adana, Kars, Elazığ, Malatya, Diyarbakır, Karabük, Zonguldak and Sivas. Commuter rail also runs between the stations of Sincan and Kayaş. On 13 March 2009, the new Yüksek Hızlı Tren (YHT) high-speed rail service began operation between Ankara and Eskişehir. On 23 August 2011, another YHT high-speed line commercially started its service between Ankara and Konya. On 25 July 2014, the Ankara–Istanbul high-speed line of YHT entered service. + +Esenboğa International Airport, located in the north-east of the city, is Ankara's main airport. + +Ankara public transportation statistics +The average amount of time people spend commuting on public transit in Ankara on a weekday is 71 minutes. 17% of public transit passengers, ride for more than two hours every day. The average amount of time people wait at a stop or station for public transit is sixteen minutes, while 28% of users wait for over twenty minutes on average every day. The average distance people usually ride in a single trip with public transit is , while 27% travel for over in a single direction. + +Politics + +Since 8 April 2019, the Mayor of Ankara is Mansur Yavaş from the Republican People's Party (CHP), who won the mayoral election in 2019. + +Ankara is politically a triple battleground between the ruling conservative AK Party, the opposition Kemalist center-left Republican People's Party (CHP) and the nationalist far-right MHP. The province of Ankara is divided into 25 districts. The CHP's key and almost only political stronghold in Ankara lies within the central area of Çankaya, which is the city's most populous district. While the CHP has always gained between 60 and 70% of the vote in Çankaya since 2002, political support elsewhere throughout Ankara is minimal. The high population within Çankaya, as well as Yenimahalle to an extent, has allowed the CHP to take overall second place behind the AK Party in both local and general elections, with the MHP a close third, despite the fact that the MHP is politically stronger than the CHP in almost every other district. Overall, the AK Party enjoys the most support throughout the city. The electorate of Ankara thus tend to vote in favor of the political right, far more so than the other main cities of Istanbul and İzmir. In retrospect, the 2013–14 protests against the AK Party government were particularly strong in Ankara, proving to be fatal on multiple occasions. The city suffered from a series of terrorist attacks in 2015 and 2016, most notably on 10 October 2015; 17 February 2016; 13 March 2016; and 15 July 2016. + +Melih Gökçek was the Metropolitan Mayor of Ankara between 1994 and 2017. Initially elected in the 1994 local elections, he was re-elected in 1999, 2004 and 2009. In the 2014 local elections, Gökçek stood for a fifth term. The MHP's metropolitan mayoral candidate for the 2009 local elections, Mansur Yavaş, stood as the CHP's candidate against Gökçek in 2014. In a heavily controversial election, Gökçek was declared the winner by just 1% ahead of Yavaş amid allegations of systematic electoral fraud. With the Supreme Electoral Council and courts rejecting his appeals, Yavaş declared his intention to take the irregularities to the European Court of Human Rights. Although Gökçek was inaugurated for a fifth term, most election observers believe that Yavaş was the winner of the election. Gökçek resigned on 28 October 2017 and was replaced by the former mayor of Sincan district, Mustafa Tuna; who was succeeded by Mansur Yavaş of the CHP, the current Mayor of Ankara, elected in 2019. + +Main sights + +Ancient/archeological sites + +Ankara Citadel +The foundations of the Ankara castle and citadel were laid by the Galatians on a prominent lava outcrop (), and the rest was completed by the Romans. The Byzantines and Seljuks further made restorations and additions. The area around and inside the citadel, being the oldest part of Ankara, contains many fine examples of traditional architecture. There are also recreational areas to relax. Many restored traditional Turkish houses inside the citadel area have found new life as restaurants, serving local cuisine. + +The citadel was depicted in various Turkish banknotes during 1927–1952 and 1983–1989. + +Roman Theater +The remains, the stage, and the backstage of the Roman theater can be seen outside the castle.

It was subsequently restored by architect Mimar Sinan in the 16th century, with Kütahya tiles being added in the 18th century. The mosque was built in honor of Hacı Bayram-ı Veli, whose tomb is next to the mosque, two years before his death (1427–28). The usable space inside this mosque is on the first floor and on the second floor. + +Ahi Elvan Mosque +It was founded in the Ulus quarter near the Ankara Citadel and was constructed by the Ahi fraternity during the late 14th and early 15th centuries.

Be proud, work hard, and believe in yourself." (There is debate on whether or not Atatürk actually said "Use your mind"(Turkish: öğün) instead of "Be proud"(Turkish: övün)) + +The monument was depicted on the reverse of the Turkish 5 lira banknote of 1937–1952 and of the 1000 lira banknotes of 1939–1946. + +Hatti Monument +Erected in 1978 at Sıhhiye Square, this impressive monument symbolizes the Hatti Sun Disc (which was later adopted by the Hittites) and commemorates Anatolia's earliest known civilization.

Turkish Angoras are one of the ancient, naturally occurring cat breeds, having originated in Ankara and its surrounding region in central Anatolia. + +They mostly have a white, silky, medium to long length coat, no undercoat and a fine bone structure. There seems to be a connection between the Angora Cats and Persians, and the Turkish Angora is also a distant cousin of the Turkish Van. Although they are known for their shimmery white coat, there are more than twenty varieties including black, blue and reddish fur. They come in tabby and tabby-white, along with smoke varieties, and are in every color other than pointed, lavender, and cinnamon (all of which would indicate breeding to an outcross.) + +Eyes may be blue, green, or amber, or even one blue and one amber or green. The W gene which is responsible for the white coat and blue eye is closely related to the hearing ability, and the presence of a blue eye can indicate that the cat is deaf to the side the blue eye is located. However, a great many blue and odd-eyed white cats have normal hearing, and even deaf cats lead a very normal life if kept indoors. + +Ears are pointed and large, eyes are almond shaped and the head is massive with a two plane profile. Another characteristic is the tail, which is often kept parallel to the back. + +Angora goat + +The Angora goat () is a breed of domestic goat that originated in Ankara and its surrounding region in central Anatolia. + +This breed was first mentioned in the time of Moses, roughly in 1500 BC. The first Angora goats were brought to Europe by Charles V, Holy Roman Emperor, about 1554, but, like later imports, were not very successful. Angora goats were first introduced in the United States in 1849 by James P. Davis. Seven adult goats were a gift from Sultan Abdülmecid I in appreciation for his services and advice on the raising of cotton. + +The fleece taken from an Angora goat is called mohair. A single goat produces between of hair per year. Angoras are shorn twice a year, unlike sheep, which are shorn only once. Angoras have high nutritional requirements due to their rapid hair growth. A poor quality diet will curtail mohair development. The United States, Turkey, and South Africa are the top producers of mohair. + +For a long period of time, Angora goats were bred for their white coat. In 1998, the Colored Angora Goat Breeders Association was set up to promote breeding of colored Angoras. Today, Angora goats produce white, black (deep black to greys and silver), red (the color fades significantly as the goat gets older), and brownish fiber. + +Angora goats were depicted on the reverse of the Turkish 50 lira banknotes of 1938–1952. + +Angora rabbit + +The Angora rabbit () is a variety of domestic rabbit bred for its long, soft hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara and its surrounding region in central Anatolia, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid-18th century, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 20th century. They are bred largely for their long Angora wool, which may be removed by shearing, combing, or plucking (gently pulling loose wool). + +Angoras are bred mainly for their wool because it is silky and soft. They have a humorous appearance, as they oddly resemble a fur ball. Most are calm and docile but should be handled carefully. Grooming is necessary to prevent the fiber from matting and felting on the rabbit. A condition called "wool block" is common in Angora rabbits and should be treated quickly. Sometimes they are shorn in the summer as the long fur can cause the rabbits to overheat. + +International relations + +Twin towns and sister cities +Ankara is twinned with: + + Seoul, South Korea (since 1971) + Islamabad, Pakistan (since 1982) + Kuala Lumpur, Malaysia (since 1984) + Beijing, China (since 1990) + Amman, Jordan (since 1992) + Bishkek, Kyrgyzstan (since 1992) + Budapest, Hungary (since 1992) + Khartoum, Sudan (since 1992) + Moscow, Russia (since 1992) + Sofia, Bulgaria (since 1992) + Havana, Cuba (since 1993) + Kyiv, Ukraine (since 1993) + Ashgabat, Turkmenistan (since 1994) + Kuwait City, Kuwait (since 1994) + Sarajevo, Bosnia and Herzegovina (since 1994) + Tirana, Albania (since 1995) + Tbilisi, Georgia (since 1996) + Ufa, Bashkortostan, Russia (since 1997) + Alanya, Turkey + Bucharest, Romania (since 1998) + Hanoi, Vietnam (since 1998) + Manama, Bahrain (since 2000) + Mogadishu, Somalia (since 2000) + Santiago, Chile (since 2000) + Astana, Kazakhstan (since 2001) + Dushanbe, Tajikistan (since 2003) + Kabul, Afghanistan (since 2003) + Ulan Bator, Mongolia (since 2003) + Cairo, Egypt (since 2004) + Chișinău, Moldova (since 2004) + Sana'a, Yemen (since 2004) + Tashkent, Uzbekistan (since 2004) + Pristina, Kosovo (since 2005) + Kazan, Tatarstan, Russia (since 2005) + Kinshasa, Democratic Republic of the Congo (since 2005) + Addis Ababa, Ethiopia (since 2006) + Minsk, Belarus (since 2007) + Zagreb, Croatia (since 2008) + Damascus, Syria (since 2010) + Bissau, Guinea-Bissau (since 2011) + Washington, D.C., USA (since 2011) + Bangkok, Thailand (since 2012) + Tehran, Iran (since 2013) + Doha, Qatar (since 2016) + Podgorica, Montenegro (since 7 March 2019) + North Nicosia, Northern Cyprus + Djibouti City, Djibouti (since 2017) + +Partner cities + Skopje, North Macedonia (since 1995) + Vienna, Austria + +See also + +Angora cat +Angora goat +Angora rabbit +Ankara Agreement +Ankara Arena +Ankara Central Station +Ankara Esenboğa International Airport +Ankara Metro +Ankara Province +Ankara University +ATO Congresium +Basil of Ancyra +Battle of Ancyra +Battle of Ankara +Clement of Ancyra +Gemellus of Ancyra +History of Ankara +List of hospitals in Ankara Province +List of mayors of Ankara +List of municipalities in Ankara Province +List of districts of Ankara +List of people from Ankara +List of tallest buildings in Ankara +Marcellus of Ancyra +Monumentum Ancyranum +Nilus of Ancyra +Roman Baths of Ankara +Synod of Ancyra +Theodotus of Ancyra (bishop) +Theodotus of Ancyra (martyr) +Timeline of Ankara +Treaty of Ankara (disambiguation) +Victory Monument (Ankara) + +Notes + +References + +Attribution + +Further reading + +External links + + Governorate of Ankara + Municipality of Ankara + GCatholic – (former and) Latin titular see + GCatholic – former and titular Armenian Catholic see + Ankara Development Agency + Esenboğa International Airport + + + +Capitals in Asia +Populated places in Ankara Province +Arabic (, ; , or ) is a Semitic language spoken primarily across the Arab world. Having emerged in the 1st century AD, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. + +Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is the language of literature, official documents, and formal written media. In spoken form, MSA is used in formal contexts, news bulletins and for prayers. This variety is the lingua franca of the Arab world and the liturgical language of Islam. It is an official language of 26 states and 1 disputed territory, the third most after English and French. It is also one of six official languages of the United Nations. + +Spoken varieties are the usual medium of communication in all other domains. They are not standardized and vary significantly, some of them being mutually unintelligible. The International Organization for Standardization assigns language codes to 33 varieties of Arabic, including MSA. Arabic vernaculars do not descend from MSA or Classical Arabic. Combined, Arabic dialects have 362 million native speakers, while MSA is spoken by 274 million L2 speakers, making it the sixth most spoken language in the world, and the most spoken that is neither Chinese nor Indo-European. + +Arabic is traditionally written with the Arabic alphabet, a right-to-left abjad and the official script for MSA. Colloquial varieties were not traditionally written; however, the emergence of social media has seen a significant increase in dialects written online. Besides the Arabic alphabet, dialects are also often written in Latin script from left to right or in Hebrew characters (in Israel) with no standardized orthography. Hassaniya is the only variety officially written in a Latin alphabet (in Senegal).; Maltese also uses a Latin script, though it is widely classified as distinct from Arabic dialects. + +Classification + +Arabic is usually classified as a Central Semitic language. Linguists still differ as to the best classification of Semitic language sub-groups. The Semitic languages changed significantly between Proto-Semitic and the emergence of Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: + The conversion of the suffix-conjugated stative formation (jalas-) into a past tense. + The conversion of the prefix-conjugated preterite-tense formation (yajlis-) into a present tense. + The elimination of other prefix-conjugated mood/aspect forms (e.g., a present tense formed by doubling the middle root, a perfect formed by infixing a after the first root consonant, probably a jussive formed by a stress shift) in favor of new moods formed by endings attached to the prefix-conjugation forms (e.g., -u for indicative, -a for subjunctive, no ending for jussive, -an or -anna for energetic). + The development of an internal passive. +There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of the northern Hejaz. These features are evidence of common descent from a hypothetical ancestor, Proto-Arabic. The following features of Proto-Arabic can be reconstructed with confidence: + negative particles * ; * to Classical Arabic + G-passive participle + prepositions and adverbs , , , , + a subjunctive in - + -demonstratives + leveling of the - allomorph of the feminine ending + complementizer and subordinator + the use of - to introduce modal clauses + independent object pronoun in + vestiges of nunation +On the other hand, several Arabic varieties are closer to other Semitic languages and maintain features not found in Classical Arabic, indicating that these varieties cannot have developed from Classical Arabic. Thus, Arabic vernaculars do not descend from Classical Arabic: Classical Arabic is a sister language rather than their direct ancestor. + +History + +Old Arabic + +Arabia had a wide variety of Semitic languages in antiquity. In the southwest, various Central Semitic languages both belonging to and outside the Ancient South Arabian family (e.g. Southern Thamudic) were spoken. It is believed that the ancestors of the Modern South Arabian languages (non-Central Semitic languages) were spoken in southern Arabia at this time. To the north, in the oases of northern Hejaz, Dadanitic and Taymanitic held some prestige as inscriptional languages. In and parts of western Arabia, a language known to scholars as Thamudic C is attested. + +In eastern Arabia, inscriptions in a script derived from ASA attest to a language known as Hasaitic. On the northwestern frontier of Arabia, various languages known to scholars as Thamudic B, Thamudic D, Safaitic, and Hismaic are attested. The last two share important isoglosses with later forms of Arabic, leading scholars to theorize that Safaitic and Hismaic are early forms of Arabic and that they should be considered Old Arabic. + +Linguists generally believe that "Old Arabic", a collection of related dialects that constitute the precursor of Arabic, first emerged around the 1st century CE. Previously, the earliest attestation of Old Arabic was thought to be a single 1st century CE inscription in Sabaic script at , in southern present-day Saudi Arabia. However, this inscription does not participate in several of the key innovations of the Arabic language group, such as the conversion of Semitic mimation to nunation in the singular. It is best reassessed as a separate language on the Central Semitic dialect continuum. + +It was also thought that Old Arabic coexisted alongside—and then gradually displaced--epigraphic Ancient North Arabian (ANA), which was theorized to have been the regional tongue for many centuries. ANA, despite its name, was considered a very distinct language, and mutually unintelligible, from "Arabic". Scholars named its variant dialects after the towns where the inscriptions were discovered (Dadanitic, Taymanitic, Hismaic, Safaitic). However, most arguments for a single ANA language or language family were based on the shape of the definite article, a prefixed h-. It has been argued that the h- is an archaism and not a shared innovation, and thus unsuitable for language classification, rendering the hypothesis of an ANA language family untenable. Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to the fact that they participate in the innovations common to all forms of Arabic. + +The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel, and dated to around 125 CE. This is followed by the Namara inscription, an epitaph of the king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From the 4th to the 6th centuries, the Nabataean script evolves into the Arabic script recognizable from the early Islamic era. There are inscriptions in an undotted, 17-letter Arabic script dating to the 6th century CE, found at four locations in Syria (Zabad, Jabal 'Usays, , ). The oldest surviving papyrus in Arabic dates to 643 CE, and it uses dots to produce the modern 28-letter Arabic alphabet. The language of that papyrus and of the Qur'an are referred to by linguists as "Quranic Arabic", as distinct from its codification soon thereafter into "Classical Arabic". + +Old Hejazi and Classical Arabic + +In late pre-Islamic times, a transdialectal and transcommunal variety of Arabic emerged in the Hejaz, which continued living its parallel life after literary Arabic had been institutionally standardized in the 2nd and 3rd century of the Hijra, most strongly in Judeo-Christian texts, keeping alive ancient features eliminated from the "learned" tradition (Classical Arabic). This variety and both its classicizing and "lay" iterations have been termed Middle Arabic in the past, but they are thought to continue an Old Higazi register. It is clear that the orthography of the Qur'an was not developed for the standardized form of Classical Arabic; rather, it shows the attempt on the part of writers to record an archaic form of Old Higazi. + +In the late 6th century AD, a relatively uniform intertribal "poetic koine" distinct from the spoken vernaculars developed based on the Bedouin dialects of Najd, probably in connection with the court of al-Ḥīra. During the first Islamic century, the majority of Arabic poets and Arabic-writing persons spoke Arabic as their mother tongue. Their texts, although mainly preserved in far later manuscripts, contain traces of non-standardized Classical Arabic elements in morphology and syntax. + +Standardization +Abu al-Aswad al-Du'ali (–689) is credited with standardizing Arabic grammar, or an-naḥw ( "the way"), and pioneering a system of diacritics to differentiate consonants ( nuqat l–i'jām "pointing for non-Arabs") and indicate vocalization ( at-tashkil). Al-Khalil ibn Ahmad al-Farahidi (718–786) compiled the first Arabic dictionary, Kitāb al-'Ayn ( "The Book of the Letter ع"), and is credited with establishing the rules of Arabic prosody. Al-Jahiz (776–868) proposed to Al-Akhfash al-Akbar an overhaul of the grammar of Arabic, but it would not come to pass for two centuries. The standardization of Arabic reached completion around the end of the 8th century. The first comprehensive description of the ʿarabiyya "Arabic", Sībawayhi's al-Kitāb, is based first of all upon a corpus of poetic texts, in addition to Qur'an usage and Bedouin informants whom he considered to be reliable speakers of the ʿarabiyya. + +Spread +Arabic spread with the spread of Islam. Following the early Muslim conquests, Arabic gained vocabulary from Middle Persian and Turkish. In the early Abbasid period, many Classical Greek terms entered Arabic through translations carried out at Baghdad's House of Wisdom. + +By the 8th century, knowledge of Classical Arabic had become an essential prerequisite for rising into the higher classes throughout the Islamic world, both for Muslims and non-Muslims. For example, Maimonides, the Andalusi Jewish philosopher, authored works in Judeo-Arabic—Arabic written in Hebrew script. + +Development +Ibn Jinni of Mosul, a pioneer in phonology, wrote prolifically in the 10th century on Arabic morphology and phonology in works such as Kitāb Al-Munṣif, Kitāb Al-Muḥtasab, and . + +Ibn Mada' of Cordoba (1116–1196) realized the overhaul of Arabic grammar first proposed by Al-Jahiz 200 years prior. + +The Maghrebi lexicographer Ibn Manzur compiled Lisān al-ʿArab (, "Tongue of Arabs"), a major reference dictionary of Arabic, in 1290. + +Neo-Arabic +Charles Ferguson's koine theory claims that the modern Arabic dialects collectively descend from a single military koine that sprang up during the Islamic conquests; this view has been challenged in recent times. Ahmad al-Jallad proposes that there were at least two considerably distinct types of Arabic on the eve of the conquests: Northern and Central (Al-Jallad 2009). The modern dialects emerged from a new contact situation produced following the conquests. Instead of the emergence of a single or multiple koines, the dialects contain several sedimentary layers of borrowed and areal features, which they absorbed at different points in their linguistic histories. According to Veersteegh and Bickerton, colloquial Arabic dialects arose from pidginized Arabic formed from contact between Arabs and conquered peoples. Pidginization and subsequent creolization among Arabs and arabized peoples could explain relative morphological and phonological simplicity of vernacular Arabic compared to Classical and MSA. + +In around the 11th and 12th centuries in al-Andalus, the zajal and muwashah poetry forms developed in the dialectical Arabic of Cordoba and the Maghreb. + +Nahda +The Nahda was a cultural and especially literary renaissance of the 19th century in which writers sought "to fuse Arabic and European forms of expression." According to James L. Gelvin, "Nahda writers attempted to simplify the Arabic language and script so that it might be accessible to a wider audience." + +In the wake of the industrial revolution and European hegemony and colonialism, pioneering Arabic presses, such as the Amiri Press established by Muhammad Ali (1819), dramatically changed the diffusion and consumption of Arabic literature and publications. Rifa'a al-Tahtawi proposed the establishment of Madrasat al-Alsun in 1836 and led a translation campaign that highlighted the need for a lexical injection in Arabic, to suit concepts of the industrial and post-industrial age (such as sayāra 'automobile' or bākhira 'steamship'). + +In response, a number of Arabic academies modeled after the were established with the aim of developing standardized additions to the Arabic lexicon to suit these transformations, first in Damascus (1919), then in Cairo (1932), Baghdad (1948), Rabat (1960), Amman (1977), (1993), and Tunis (1993). They review language development, monitor new words and approve inclusion of new words into their published standard dictionaries. They also publish old and historical Arabic manuscripts. + +In 1997, a bureau of Arabization standardization was added to the Educational, Cultural, and Scientific Organization of the Arab League. These academies and organizations have worked toward the Arabization of the sciences, creating terms in Arabic to describe new concepts, toward the standardization of these new terms throughout the Arabic-speaking world, and toward the development of Arabic as a world language. This gave rise to what Western scholars call Modern Standard Arabic. From the 1950s, Arabization became a postcolonial nationalist policy in countries such as Tunisia, Algeria, Morocco, and Sudan. + +Classical, Modern Standard and spoken Arabic +Arabic usually refers to Standard Arabic, which Western linguists divide into Classical Arabic and Modern Standard Arabic. It could also refer to any of a variety of regional vernacular Arabic dialects, which are not necessarily mutually intelligible.Classical Arabic is the language found in the Quran, used from the period of Pre-Islamic Arabia to that of the Abbasid Caliphate. Classical Arabic is prescriptive, according to the syntactic and grammatical norms laid down by classical grammarians (such as Sibawayh) and the vocabulary defined in classical dictionaries (such as the Lisān al-ʻArab). + +Modern Standard Arabic (MSA) largely follows the grammatical standards of Classical Arabic and uses much of the same vocabulary. However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties and has adopted certain new constructions and vocabulary from the spoken varieties. Much of the new vocabulary is used to denote concepts that have arisen in the industrial and post-industrial era, especially in modern times. + +Due to its grounding in Classical Arabic, Modern Standard Arabic is removed over a millennium from everyday speech, which is construed as a multitude of dialects of this language. These dialects and Modern Standard Arabic are described by some scholars as not mutually comprehensible. The former are usually acquired in families, while the latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children. + +The relation between Modern Standard Arabic and these dialects is sometimes compared to that of Classical Latin and Vulgar Latin vernaculars (which became Romance languages) in medieval and early modern Europe. +MSA is the variety used in most current, printed Arabic publications, spoken by some of the Arabic media across North Africa and the Middle East, and understood by most educated Arabic speakers. "Literary Arabic" and "Standard Arabic" ( ) are less strictly defined terms that may refer to Modern Standard Arabic or Classical Arabic. + +Some of the differences between Classical Arabic (CA) and Modern Standard Arabic (MSA) are as follows: + Certain grammatical constructions of CA that have no counterpart in any modern vernacular dialect (e.g., the energetic mood) are almost never used in Modern Standard Arabic. + Case distinctions are very rare in Arabic vernaculars. As a result, MSA is generally composed without case distinctions in mind, and the proper cases are added after the fact, when necessary. Because most case endings are noted using final short vowels, which are normally left unwritten in the Arabic script, it is unnecessary to determine the proper case of most words. The practical result of this is that MSA, like English and Standard Chinese, is written in a strongly determined word order and alternative orders that were used in CA for emphasis are rare. In addition, because of the lack of case marking in the spoken varieties, most speakers cannot consistently use the correct endings in extemporaneous speech. As a result, spoken MSA tends to drop or regularize the endings except when reading from a prepared text. +The numeral system in CA is complex and heavily tied in with the case system. This system is never used in MSA, even in the most formal of circumstances; instead, a significantly simplified system is used, approximating the system of the conservative spoken varieties. + +MSA uses much Classical vocabulary (e.g., 'to go') that is not present in the spoken varieties, but deletes Classical words that sound obsolete in MSA. In addition, MSA has borrowed or coined many terms for concepts that did not exist in Quranic times, and MSA continues to evolve. Some words have been borrowed from other languages—notice that transliteration mainly indicates spelling and not real pronunciation (e.g., 'film' or 'democracy'). + +The current preference is to avoid direct borrowings, preferring to either use loan translations (e.g., 'branch', also used for the branch of a company or organization; 'wing', is also used for the wing of an airplane, building, air force, etc.), or to coin new words using forms within existing roots ( 'apoptosis', using the root m/w/t 'death' put into the Xth form, or 'university', based on 'to gather, unite'; 'republic', based on 'multitude'). An earlier tendency was to redefine an older word although this has fallen into disuse (e.g., 'telephone' < 'invisible caller (in Sufism)'; 'newspaper' < 'palm-leaf stalk'). + +Colloquial or dialectal Arabic refers to the many national or regional varieties which constitute the everyday spoken language. Colloquial Arabic has many regional variants; geographically distant varieties usually differ enough to be mutually unintelligible, and some linguists consider them distinct languages. However, research indicates a high degree of mutual intelligibility between closely related Arabic variants for native speakers listening to words, sentences, and texts; and between more distantly related dialects in interactional situations.The varieties are typically unwritten. They are often used in informal spoken media, such as soap operas and talk shows, as well as occasionally in certain forms of written media such as poetry and printed advertising. + +Hassaniya Arabic, Maltese, and Cypriot Arabic are only varieties of modern Arabic to have acquired official recognition. Hassaniya is official in Mali and recognized as a minority language in Morocco, while the Senegalese government adopted the Latin script to write it. Maltese is official in (predominantly Catholic) Malta and written with the Latin script. Linguists agree that it is a variety of spoken Arabic, descended from Siculo-Arabic, though it has experienced extensive changes as a result of sustained and intensive contact with Italo-Romance varieties, and more recently also with English. Due to "a mix of social, cultural, historical, political, and indeed linguistic factors," many Maltese people today consider their language Semitic but not a type of Arabic. Cypriot Arabic is recognized as a minority language in Cyprus. + +Status and usage + +Diglossia +The sociolinguistic situation of Arabic in modern times provides a prime example of the linguistic phenomenon of diglossia, which is the normal use of two separate varieties of the same language, usually in different social situations. Tawleed is the process of giving a new shade of meaning to an old classical word. For example, al-hatif lexicographically, means the one whose sound is heard but whose person remains unseen. Now the term al-hatif is used for a telephone. Therefore, the process of tawleed can express the needs of modern civilization in a manner that would appear to be originally Arabic. + +In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native dialects, which depending on the region may be mutually unintelligible. Some of these dialects can be considered to constitute separate languages which may have "sub-dialects" of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within the same sentence. Arabic speakers often improve their familiarity with other dialects via music or film. + +The issue of whether Arabic is one language or many languages is politically charged, in the same way it is for the varieties of Chinese, Hindi and Urdu, Serbian and Croatian, Scots and English, etc. In contrast to speakers of Hindi and Urdu who claim they cannot understand each other even when they can, speakers of the varieties of Arabic will claim they can all understand each other even when they cannot. + +While there is a minimum level of comprehension between all Arabic dialects, this level can increase or decrease based on geographic proximity: for example, Levantine and Gulf speakers understand each other much better than they do speakers from the Maghreb. The issue of diglossia between spoken and written language is a significant complicating factor: A single written form, significantly different from any of the spoken varieties learned natively, unites a number of sometimes divergent spoken forms. For political reasons, Arabs mostly assert that they all speak a single language, despite significant issues of mutual incomprehensibility among differing spoken versions. + +From a linguistic standpoint, it is often said that the various spoken varieties of Arabic differ among each other collectively about as much as the Romance languages. This is an apt comparison in a number of ways. The period of divergence from a single spoken form is similar—perhaps 1500 years for Arabic, 2000 years for the Romance languages. Also, while it is comprehensible to people from the Maghreb, a linguistically innovative variety such as Moroccan Arabic is essentially incomprehensible to Arabs from the Mashriq, much as French is incomprehensible to Spanish or Italian speakers but relatively easily learned by them. This suggests that the spoken varieties may linguistically be considered separate languages. + +Status in the Arab world vis-à-vis other languages +With the sole example of Medieval linguist Abu Hayyan al-Gharnati – who, while a scholar of the Arabic language, was not ethnically Arab – Medieval scholars of the Arabic language made no efforts at studying comparative linguistics, considering all other languages inferior. + +In modern times, the educated upper classes in the Arab world have taken a nearly opposite view. Yasir Suleiman wrote in 2011 that "studying and knowing English or French in most of the Middle East and North Africa have become a badge of sophistication and modernity and ... feigning, or asserting, weakness or lack of facility in Arabic is sometimes paraded as a sign of status, class, and perversely, even education through a mélange of code-switching practises." + +As a foreign language +Arabic has been taught worldwide in many elementary and secondary schools, especially Muslim schools. Universities around the world have classes that teach Arabic as part of their foreign languages, Middle Eastern studies, and religious studies courses. Arabic language schools exist to assist students to learn Arabic outside the academic world. There are many Arabic language schools in the Arab world and other Muslim countries. Because the Quran is written in Arabic and all Islamic terms are in Arabic, millions of Muslims (both Arab and non-Arab) study the language. + +Software and books with tapes are an important part of Arabic learning, as many of Arabic learners may live in places where there are no academic or Arabic language school classes available. Radio series of Arabic language classes are also provided from some radio stations. A number of websites on the Internet provide online classes for all levels as a means of distance education; most teach Modern Standard Arabic, but some teach regional varieties from numerous countries. + +Vocabulary + +Lexicography + +Pre-modern Arabic lexicography +The tradition of Arabic lexicography extended for about a millennium before the modern period. Early lexicographers ( lughawiyyūn) sought to explain words in the Quran that were unfamiliar or had a particular contextual meaning, and to identify words of non-Arabic origin that appear in the Quran. They gathered shawāhid ( 'instances of attested usage') from poetry and the speech of the Arabs—particularly the Bedouin () who were perceived to speak the “purest,” most eloquent form of Arabic—initiating a process of jamʿ al-lugha ( 'compiling the language') which took place over the 8th and early 9th centuries.Kitāb al-'Ayn (), attributed to Al-Khalil ibn Ahmad al-Farahidi, is considered the first lexicon to include all Arabic roots; it sought to exhaust all possible root permutations—later called taqālīb ()—calling those that are actually used mustaʿmal () and those that are not used muhmal (). Lisān al-ʿArab (1290) by Ibn Manzur gives 9,273 roots, while Tāj al-ʿArūs (1774) by Murtada az-Zabidi gives 11,978 roots. + +This lexicographic tradition was traditionalist and corrective in nature—holding that linguistic correctness and eloquence derive from Qurʾānic usage, , and Bedouin speech—positioning itself against laḥn al-ʿāmma (), the solecism it viewed as defective. + +Western lexicography of Arabic +In the second half of the 19th century, the British Arabist Edward William Lane, working with the Egyptian scholar , compiled the Arabic–English Lexicon by translating material from earlier Arabic lexica into English. The German Arabist Hans Wehr, with contributions from Hedwig Klein, compiled the Arabisches Wörterbuch für die Schriftsprache der Gegenwart (1952), later translated into English as A Dictionary of Modern Written Arabic (1961), based on established usage, especially in literature. + +Modern Arabic lexicography +The Academy of the Arabic Language in Cairo sought to publish a historical dictionary of Arabic in the vein of the Oxford English Dictionary, tracing the changes of meanings and uses of Arabic words over time. A first volume of Al-Muʿjam al-Kabīr was published in 1956 under the leadership of Taha Hussein. The project is not yet complete; its 15th volume, covering the letter ṣād, was published in 2022. + +Loanwords + +The most important sources of borrowings into (pre-Islamic) Arabic are from the related (Semitic) languages Aramaic, which used to be the principal, international language of communication throughout the ancient Near and Middle East, and Ethiopic. Many cultural, religious and political terms have entered Arabic from Iranian languages, notably Middle Persian, Parthian, and (Classical) Persian, and Hellenistic Greek (kīmiyāʼ has as origin the Greek khymia, meaning in that language the melting of metals; see Roger Dachez, Histoire de la Médecine de l'Antiquité au XXe siècle, Tallandier, 2008, p. 251), alembic (distiller) from ambix (cup), almanac (climate) from almenichiakon (calendar). + +For the origin of the last three borrowed words, see Alfred-Louis de Prémare, Foundations of Islam, Seuil, L'Univers Historique, 2002. Some Arabic borrowings from Semitic or Persian languages are, as presented in De Prémare's above-cited book: +madīnah/medina (مدينة, city or city square), a word of Aramaic origin ܡܕ݂ܝܼܢ݇ܬܵܐ/"məḏī(n)ttā" (in which it means "state/city"). +jazīrah (جزيرة), as in the well-known form الجزيرة "Al-Jazeera", means "island" and has its origin in the Syriac ܓܵܙܲܪܬܵܐ gāzartā. +lāzaward (لازورد) is taken from Persian لاژورد lājvard, the name of a blue stone, lapis lazuli. This word was borrowed in several European languages to mean (light) blue – azure in English, azur in French and azul in Portuguese and Spanish. +A comprehensive overview of the influence of other languages on Arabic is found in Lucas & Manfredi (2020). + +Influence of Arabic on other languages +The influence of Arabic has been most important in Islamic countries, because it is the language of the Islamic sacred book, the Quran. Arabic is also an important source of vocabulary for languages such as Amharic, Azerbaijani, Baluchi, Bengali, Berber, Bosnian, Chaldean, Chechen, Chittagonian, Croatian, Dagestani, Dhivehi, English, German, Gujarati, Hausa, Hindi, Kazakh, Kurdish, Kutchi, Kyrgyz, Malay (Malaysian and Indonesian), Pashto, Persian, Punjabi, Rohingya, Romance languages (French, Catalan, Italian, Portuguese, Sicilian, Spanish, etc.) Saraiki, Sindhi, Somali, Sylheti, Swahili, Tagalog, Tigrinya, Turkish, Turkmen, Urdu, Uyghur, Uzbek, Visayan and Wolof, as well as other languages in countries where these languages are spoken. Modern Hebrew has been also influenced by Arabic especially during the process of revival, as MSA was used as a source for modern Hebrew vocabulary and roots. + +English has many Arabic loanwords, some directly, but most via other Mediterranean languages. Examples of such words include admiral, adobe, alchemy, alcohol, algebra, algorithm, alkaline, almanac, amber, arsenal, assassin, candy, carat, cipher, coffee, cotton, ghoul, hazard, jar, kismet, lemon, loofah, magazine, mattress, sherbet, sofa, sumac, tariff, and zenith. Other languages such as Maltese and Kinubi derive ultimately from Arabic, rather than merely borrowing vocabulary or grammatical rules. + +Terms borrowed range from religious terminology (like Berber taẓallit, "prayer", from salat ( )), academic terms (like Uyghur mentiq, "logic"), and economic items (like English coffee) to placeholders (like Spanish fulano, "so-and-so"), everyday terms (like Hindustani lekin, "but", or Spanish taza and French tasse, meaning "cup"), and expressions (like Catalan a betzef, "galore, in quantity"). Most Berber varieties (such as Kabyle), along with Swahili, borrow some numbers from Arabic. Most Islamic religious terms are direct borrowings from Arabic, such as (salat), "prayer", and (imam), "prayer leader." + +In languages not directly in contact with the Arab world, Arabic loanwords are often transferred indirectly via other languages rather than being transferred directly from Arabic. For example, most Arabic loanwords in Hindustani and Turkish entered through Persian. Older Arabic loanwords in Hausa were borrowed from Kanuri. Most Arabic loanwords in Yoruba entered through Hausa. + +Arabic words made their way into several West African languages as Islam spread across the Sahara. Variants of Arabic words such as kitāb ("book") have spread to the languages of African groups who had no direct contact with Arab traders. + +Since, throughout the Islamic world, Arabic occupied a position similar to that of Latin in Europe, many of the Arabic concepts in the fields of science, philosophy, commerce, etc. were coined from Arabic roots by non-native Arabic speakers, notably by Aramaic and Persian translators, and then found their way into other languages. This process of using Arabic roots, especially in Kurdish and Persian, to translate foreign concepts continued through to the 18th and 19th centuries, when swaths of Arab-inhabited lands were under Ottoman rule. + +Spoken varieties + +Colloquial Arabic is a collective term for the spoken dialects of Arabic used throughout the Arab world, which differ radically from the literary language. The main dialectal division is between the varieties within and outside of the Arabian peninsula, followed by that between sedentary varieties and the much more conservative Bedouin varieties. All the varieties outside of the Arabian peninsula, which include the large majority of speakers, have many features in common with each other that are not found in Classical Arabic. This has led researchers to postulate the existence of a prestige koine dialect in the one or two centuries immediately following the Arab conquest, whose features eventually spread to all newly conquered areas. These features are present to varying degrees inside the Arabian peninsula. Generally, the Arabian peninsula varieties have much more diversity than the non-peninsula varieties, but these have been understudied.Within the non-peninsula varieties, the largest difference is between the non-Egyptian North African dialects, especially Moroccan Arabic, and the others. Moroccan Arabic in particular is hardly comprehensible to Arabic speakers east of Libya (although the converse is not true, in part due to the popularity of Egyptian films and other media). + +One factor in the differentiation of the dialects is influence from the languages previously spoken in the areas, which have typically provided a significant number of new words and have sometimes also influenced pronunciation or word order. However, a much more significant factor for most dialects is, as among Romance languages, retention (or change of meaning) of different classical forms. Thus Iraqi aku, Levantine fīh and North African kayən all mean 'there is', and all come from Classical Arabic forms (yakūn, fīhi, kā'in respectively), but now sound very different. + +Koiné +According to Charles A. Ferguson, the following are some of the characteristic features of the koiné that underlies all the modern dialects outside the Arabian peninsula. Although many other features are common to most or all of these varieties, Ferguson believes that these features in particular are unlikely to have evolved independently more than once or twice and together suggest the existence of the koine: + Loss of the dual number except on nouns, with consistent plural agreement (cf. feminine singular agreement in plural inanimates). + Change of a to i in many affixes (e.g., non-past-tense prefixes ti- yi- ni-; wi- 'and'; il- 'the'; feminine -it in the construct state). + Loss of third-weak verbs ending in w (which merge with verbs ending in y). + Reformation of geminate verbs, e.g., 'I untied' → . + Conversion of separate words lī 'to me', laka 'to you', etc. into indirect-object clitic suffixes. + Certain changes in the cardinal number system, e.g., 'five days' → , where certain words have a special plural with prefixed t. + Loss of the feminine elative (comparative). + Adjective plurals of the form 'big' → . + Change of nisba suffix > . + Certain lexical items, e.g., 'bring' < 'come with'; 'see'; 'what' (or similar) < 'which thing'; (relative pronoun). + Merger of and . + +Dialect groups + Egyptian Arabic is spoken by 67 million people in Egypt. It is one of the most understood varieties of Arabic, due in large part to the widespread distribution of Egyptian films and television shows throughout the Arabic-speaking world + Levantine Arabic is spoken by about 44 million people in Lebanon, Syria, Jordan, Palestine, Israel, and Turkey. + Lebanese Arabic is a variety of Levantine Arabic spoken primarily in Lebanon. + Jordanian Arabic is a continuum of mutually intelligible varieties of Levantine Arabic spoken by the population of the Kingdom of Jordan. + Palestinian Arabic is a name of several dialects of the subgroup of Levantine Arabic spoken by the Palestinians in Palestine, by Arab citizens of Israel and in most Palestinian populations around the world. + Samaritan Arabic, spoken by only several hundred in the Nablus region + Cypriot Maronite Arabic, spoken in Cyprus by around 9,800 people (2013 UNSD) + Maghrebi Arabic, also called "Darija" spoken by about 70 million people in Morocco, Algeria, Tunisia and Libya. It also forms the basis of Maltese via the extinct Sicilian Arabic dialect. Maghrebi Arabic is very hard to understand for Arabic speakers from the Mashriq or Mesopotamia, the most comprehensible being Libyan Arabic and the most difficult Moroccan Arabic. The others such as Algerian Arabic can be considered in between the two in terms of difficulty. + Libyan Arabic spoken in Libya and neighboring countries. + Tunisian Arabic spoken in Tunisia and North-eastern Algeria + Algerian Arabic spoken in Algeria + Judeo-Algerian Arabic was spoken by Jews in Algeria until 1962 + Moroccan Arabic spoken in Morocco + Hassaniya Arabic (3 million speakers), spoken in Mauritania, Western Sahara, some parts of the Azawad in northern Mali, southern Morocco and south-western Algeria. + Andalusian Arabic, spoken in Spain until the 16th century. + Siculo-Arabic (Sicilian Arabic), was spoken in Sicily and Malta between the end of the 9th century and the end of the 12th century and eventually evolved into the Maltese language. + Maltese, spoken on the island of Malta, is the only fully separate standardized language to have originated from an Arabic dialect, the extinct Siculo-Arabic dialect, with independent literary norms. Maltese has evolved independently of Modern Standard Arabic and its varieties into a standardized language over the past 800 years in a gradual process of Latinisation. Maltese is therefore considered an exceptional descendant of Arabic that has no diglossic relationship with Standard Arabic or Classical Arabic. Maltese is different from Arabic and other Semitic languages since its morphology has been deeply influenced by Romance languages, Italian and Sicilian. It is the only Semitic language written in the Latin script. In terms of basic everyday language, speakers of Maltese are reported to be able to understand less than a third of what is said to them in Tunisian Arabic, which is related to Siculo-Arabic, whereas speakers of Tunisian are able to understand about 40% of what is said to them in Maltese. This asymmetric intelligibility is considerably lower than the mutual intelligibility found between Maghrebi Arabic dialects. Maltese has its own dialects, with urban varieties of Maltese being closer to Standard Maltese than rural varieties. + Mesopotamian Arabic, spoken by about 41.2 million people in Iraq (where it is called "Aamiyah"), eastern Syria and southwestern Iran (Khuzestan) and in the southeastern of Turkey (in the eastern Mediterranean, Southeastern Anatolia Region) +North Mesopotamian Arabic is a spoken north of the Hamrin Mountains in Iraq, in western Iran, northern Syria, and in southeastern Turkey (in the eastern Mediterranean Region, Southeastern Anatolia Region, and southern Eastern Anatolia Region). +Judeo-Mesopotamian Arabic, also known as Iraqi Judeo Arabic and Yahudic, is a variety of Arabic spoken by Iraqi Jews of Mosul. +Baghdad Arabic is the Arabic dialect spoken in Baghdad, and the surrounding cities and it is a subvariety of Mesopotamian Arabic. +Baghdad Jewish Arabic is the dialect spoken by the Iraqi Jews of Baghdad. +South Mesopotamian Arabic (Basrawi dialect) is the dialect spoken in southern Iraq, such as Basra, Dhi Qar and Najaf. +Khuzestani Arabic is the dialect spoken in the Iranian province of Khuzestan.

It is also spoken to a lesser extent in Oman. + Judeo-Arabic dialects – these are the dialects spoken by the Jews that had lived or continue to live in the Arab World.

Various other consonants have changed their sound too, but have remained distinct. An original lenited to , and – consistently attested in pre-Islamic Greek transcription of Arabic languages – became palatalized to or by the time of the Quran and , , or after early Muslim conquests and in MSA (see Arabic phonology#Local variations for more detail). An original voiceless alveolar lateral fricative became . + +Its emphatic counterpart was considered by Arabs to be the most unusual sound in Arabic (Hence the Classical Arabic's appellation or "language of the "). For most modern dialects, it has become an emphatic stop with loss of the laterality or with complete loss of any pharyngealization or velarization, . The classical pronunciation of pharyngealization still occurs in the Mehri language, and the similar sound without velarization, , exists in other Modern South Arabian languages.Other changes may also have happened. Classical Arabic pronunciation is not thoroughly recorded and different reconstructions of the sound system of Proto-Semitic propose different phonetic values. One example is the emphatic consonants, which are pharyngealized in modern pronunciations but may have been velarized in the eighth century and glottalized in Proto-Semitic. + +Reduction of and between vowels occurs in a number of circumstances and is responsible for much of the complexity of third-weak ("defective") verbs. Early Akkadian transcriptions of Arabic names shows that this reduction had not yet occurred as of the early part of the 1st millennium BC. + +The Classical Arabic language as recorded was a poetic koine that reflected a conscious + +ly archaizing dialect, chosen based on the tribes of the western part of the Arabian Peninsula, who spoke the most conservative variants of Arabic. Even at the time of Muhammed and before, other dialects existed with many more changes, including the loss of most glottal stops, the loss of case endings, the reduction of the diphthongs and into monophthongs , etc. Most of these changes are present in most or all modern varieties of Arabic. + +An interesting feature of the writing system of the Quran (and hence of Classical Arabic) is that it contains certain features of Muhammad's native dialect of Mecca, corrected through diacritics into the forms of standard Classical Arabic. Among these features visible under the corrections are the loss of the glottal stop and a differing development of the reduction of certain final sequences containing : Evidently, final became as in the Classical language, but final became a different sound, possibly (rather than again in the Classical language). This is the apparent source of the alif maqṣūrah 'restricted alif' where a final is reconstructed: a letter that would normally indicate or some similar high-vowel sound, but is taken in this context to be a logical variant of alif and represent the sound . + +Literary Arabic + +The "colloquial" spoken dialects of Arabic are learned at home and constitute the native languages of Arabic speakers. "Formal" Modern Standard Arabic is learned at school; although many speakers have a native-like command of the language, it is technically not the native language of any speakers. Both varieties can be both written and spoken, although the colloquial varieties are rarely written down and the formal variety is spoken mostly in formal circumstances, e.g., in radio and TV broadcasts, formal lectures, parliamentary discussions and to some extent between speakers of different colloquial dialects. + +Even when the literary language is spoken, it is normally only spoken in its pure form when reading a prepared text out loud and communication between speakers of different colloquial dialects. When speaking extemporaneously (i.e. making up the language on the spot, as in a normal discussion among people), speakers tend to deviate somewhat from the strict literary language in the direction of the colloquial varieties. There is a continuous range of "in-between" spoken varieties: from nearly pure Modern Standard Arabic (MSA), to a form that still uses MSA grammar and vocabulary but with significant colloquial influence, to a form of the colloquial language that imports a number of words and grammatical constructions in MSA, to a form that is close to pure colloquial but with the "rough edges" (the most noticeably "vulgar" or non-Classical aspects) smoothed out, to pure colloquial. + +The particular variant (or register) used depends on the social class and education level of the speakers involved and the level of formality of the speech situation. Often it will vary within a single encounter, e.g., moving from nearly pure MSA to a more mixed language in the process of a radio interview, as the interviewee becomes more comfortable with the interviewer. This type of variation is characteristic of the diglossia that exists throughout the Arabic-speaking world. + +Although Modern Standard Arabic (MSA) is a unitary language, its pronunciation varies somewhat from country to country and from region to region within a country. The variation in individual "accents" of MSA speakers tends to mirror corresponding variations in the colloquial speech of the speakers in question, but with the distinguishing characteristics moderated somewhat. It is important in descriptions of "Arabic" phonology to distinguish between pronunciation of a given colloquial (spoken) dialect and the pronunciation of MSA by these same speakers. + +Although they are related, they are not the same. For example, the phoneme that derives from Classical Arabic has many different pronunciations in the modern spoken varieties, e.g., including the proposed original . Speakers whose native variety has either or will use the same pronunciation when speaking MSA. Even speakers from Cairo, whose native Egyptian Arabic has , normally use when speaking MSA. The of Persian Gulf speakers is the only variant pronunciation which is not found in MSA; is used instead, but may use [j] in MSA for comfortable pronunciation. + +Another reason of different pronunciations is influence of colloquial dialects. The differentiation of pronunciation of colloquial dialects is the influence from other languages previously spoken and some still presently spoken in the regions, such as Coptic in Egypt, Berber, Punic, or Phoenician in North Africa, Himyaritic, Modern South Arabian, and Old South Arabian in Yemen and Oman, and Aramaic and Canaanite languages (including Phoenician) in the Levant and Mesopotamia. + +Another example: Many colloquial varieties are known for a type of vowel harmony in which the presence of an "emphatic consonant" triggers backed allophones of nearby vowels (especially of the low vowels , which are backed to in these circumstances and very often fronted to in all other circumstances). In many spoken varieties, the backed or "emphatic" vowel allophones spread a fair distance in both directions from the triggering consonant. In some varieties, most notably Egyptian Arabic, the "emphatic" allophones spread throughout the entire word, usually including prefixes and suffixes, even at a distance of several syllables from the triggering consonant. + +Speakers of colloquial varieties with this vowel harmony tend to introduce it into their MSA pronunciation as well, but usually with a lesser degree of spreading than in the colloquial varieties. For example, speakers of colloquial varieties with extremely long-distance harmony may allow a moderate, but not extreme, amount of spreading of the harmonic allophones in their MSA speech, while speakers of colloquial varieties with moderate-distance harmony may only harmonize immediately adjacent vowels in MSA. + +Vowels + +Modern Standard Arabic has six pure vowels (while most modern dialects have eight pure vowels which includes the long vowels ), with short and corresponding long vowels . There are also two diphthongs: and . + +The pronunciation of the vowels differs from speaker to speaker, in a way that tends to reflect the pronunciation of the corresponding colloquial variety. Nonetheless, there are some common trends. Most noticeable is the differing pronunciation of and , which tend towards fronted , or in most situations, but a back in the neighborhood of emphatic consonants. Some accents and dialects, such as those of the Hejaz region, have an open or a central in all situations. The vowel varies towards too. Listen to the final vowel in the recording of at the beginning of this article, for example. + +The point is, Arabic has only three short vowel phonemes, so those phonemes can have a very wide range of allophones. The vowels and are often affected somewhat in emphatic neighborhoods as well, with generally more back or centralized allophones, but the differences are less great than for the low vowels. The pronunciation of short and tends towards and , respectively, in many dialects. + +The definition of both "emphatic" and "neighborhood" vary in ways that reflect (to some extent) corresponding variations in the spoken dialects. Generally, the consonants triggering "emphatic" allophones are the pharyngealized consonants ; ; and , if not followed immediately by . Frequently, the fricatives trigger emphatic allophones, occasionally also the pharyngeal consonants , the former more than the latter. + +Many dialects have multiple emphatic allophones of each vowel, depending on the particular nearby consonants. In most MSA accents, emphatic coloring of vowels is limited to vowels immediately adjacent to a triggering consonant, although in some it spreads a bit farther: e.g., 'time'; 'homeland'; 'downtown' (also or similar). + +In a non-emphatic environment, the vowel in the diphthong is pronounced or : hence 'sword' but 'summer'. However, in accents with no emphatic allophones of (e.g., in the Hejaz), the pronunciation or occurs in all situations. + +Consonants + +The phoneme is represented by the Arabic letter () and has many standard pronunciations. is characteristic of north Algeria, Iraq, and most of the Arabian peninsula but with an allophonic in some positions; occurs in most of the Levant and most of North Africa; and is standard in Egypt, coastal Yemen, as well as eastern and coastal western Oman. Generally this corresponds with the pronunciation in the colloquial dialects. In Sudan and Yemen, as well as in some Sudanese and Yemeni varieties, it may be either or , representing the original pronunciation of Classical Arabic. Foreign words containing may be transcribed with , , , , , or , depending on the regional practice. In northern Egypt, where the Arabic letter () is normally pronounced , a separate phoneme , which may be transcribed with , occurs in a small number of mostly non-Arabic loanwords, e.g., 'jacket'. + + () can be pronounced as . In some places of Maghreb it can be also pronounced as . + + and () are velar, post-velar, or uvular. + +In many varieties, () are epiglottal in West Asia. + + is pronounced as velarized in الله , the name of God, q.e. Allah, when the word follows a, ā, u or ū (after i or ī it is unvelarized: bismi l–lāh ). + +The emphatic consonant was actually pronounced , or possibly —either way, a highly unusual sound. The medieval Arabs actually termed their language 'the language of the Ḍād' (the name of the letter used for this sound), since they thought the sound was unique to their language. (In fact, it also exists in a few other minority Semitic languages, e.g., Mehri.) + +Arabic has consonants traditionally termed "emphatic" (), which exhibit simultaneous pharyngealization as well as varying degrees of velarization (depending on the region), so they may be written with the "Velarized or pharyngealized" diacritic () as: . This simultaneous articulation is described as "Retracted Tongue Root" by phonologists. In some transcription systems, emphasis is shown by capitalizing the letter, for example, is written ; in others the letter is underlined or has a dot below it, for example, . + +Vowels and consonants can be phonologically short or long. Long (geminate) consonants are normally written doubled in Latin transcription (i.e. bb, dd, etc.), reflecting the presence of the Arabic diacritic mark , which indicates doubled consonants. In actual pronunciation, doubled consonants are held twice as long as short consonants. This consonant lengthening is phonemically contrastive: 'he accepted' vs. 'he kissed'. + +Syllable structure +Arabic has two kinds of syllables: open syllables (CV) and (CVV)—and closed syllables (CVC), (CVVC) and (CVCC). The syllable types with two morae (units of time), i.e. CVC and CVV, are termed heavy syllables, while those with three morae, i.e. CVVC and CVCC, are superheavy syllables. Superheavy syllables in Classical Arabic occur in only two places: at the end of the sentence (due to pausal pronunciation) and in words such as 'hot', 'stuff, substance', 'they disputed with each other', where a long occurs before two identical consonants. A former short vowel between the consonants has been lost. In less formal pronunciations of Modern Standard Arabic, superheavy syllables are common at the end of words or before clitic suffixes such as 'us, our', due to the deletion of final short vowels. + +In surface pronunciation, every vowel must be preceded by a consonant (which may include the glottal stop ). There are no cases of hiatus within a word, where two vowels occur next to each other, without an intervening consonant. Some words do have an underlying vowel at the beginning, such as the definite article al- or words such as 'he bought', 'meeting'. When actually pronounced, one of three things happens: + If the word occurs after another word ending in a consonant, there is a smooth transition from final consonant to initial vowel, e.g., 'meeting' . + If the word occurs after another word ending in a vowel, the initial vowel of the word is elided, e.g., 'house of the director' . + If the word occurs at the beginning of an utterance, a glottal stop is added onto the beginning, e.g., 'The house is ...' . + +Stress +Word stress is not phonemically contrastive in Standard Arabic. It bears a strong relationship to vowel length. The basic rules for Modern Standard Arabic are: + A final vowel, long or short, may not be stressed. + Only one of the last three syllables may be stressed. + Given this restriction, the last heavy syllable, containing a long vowel or ending in a consonant, is stressed, if it is not the final syllable. + If the final syllable is super heavy and closed (of the form CVVC or CVCC) it receives stress. + If no syllable is heavy or super heavy, the first possible syllable (i.e. third from end) is stressed. + As a special exception, in Form VII and VIII verb forms stress may not be on the first syllable, despite the above rules: Hence 'he subscribed' (whether or not the final short vowel is pronounced), 'he subscribes' (whether or not the final short vowel is pronounced), 'he should subscribe (juss.)'. Likewise Form VIII 'he bought', 'he buys'. + +These rules may result in differently stressed syllables when final case endings are pronounced, vs. the normal situation where they are not pronounced, as in the above example of 'library' in full pronunciation, but 'library' in short pronunciation. + +The restriction on final long vowels does not apply to the spoken dialects, where original final long vowels have been shortened and secondary final long vowels have arisen from loss of original final -hu/hi. + +Some dialects have different stress rules. In the Egyptian Arabic dialect a heavy syllable may not carry stress more than two syllables from the end of a word, hence 'school', 'Cairo'. This also affects the way that Modern Standard Arabic is pronounced in Egypt. In the Arabic of Sanaa, stress is often retracted: 'two houses', 'their table', 'desks', 'sometimes', 'their school'. In this dialect, only syllables with long vowels or diphthongs are considered heavy; in a two-syllable word, the final syllable can be stressed only if the preceding syllable is light; and in longer words, the final syllable cannot be stressed. + +Levels of pronunciation +The final short vowels (e.g., the case endings -a -i -u and mood endings -u -a) are often not pronounced in this language, despite forming part of the formal paradigm of nouns and verbs. The following levels of pronunciation exist: + +Full pronunciation with pausa +This is the most formal level actually used in speech. All endings are pronounced as written, except at the end of an utterance, where the following changes occur: + Final short vowels are not pronounced. But possibly an exception is made for feminine plural -na and shortened vowels in the jussive/imperative of defective verbs, e.g., irmi! 'throw!. + The entire indefinite noun endings -in and -un (with nunation) are left off. The ending -an is left off of nouns preceded by a tāʾ marbūṭah ة i.e. the -t in the ending -at- that typically marks feminine nouns), but pronounced as -ā in other nouns, hence its writing in this fashion in the Arabic script. + The tāʼ marbūṭah itself typically of feminine nouns is pronounced as h. At least, this is the case in extremely formal pronunciation, e.g., some Quranic recitations. In practice, this h is usually omitted. + +Formal short pronunciation +This is a formal level of pronunciation sometimes seen. It is somewhat like pronouncing all words as if they were in pausal position (with influence from the colloquial varieties). The following changes occur: + Most final short vowels are not pronounced. The following short vowels are pronounced: + feminine plural -na + shortened vowels in the jussive/imperative of defective verbs, e.g., irmi! 'throw!' + second-person singular feminine past-tense -ti and likewise anti 'you (fem. sg.)' + sometimes, first-person singular past-tense -tu + sometimes, second-person masculine past-tense -ta and likewise anta 'you (masc. sg.)' + final -a in certain short words, e.g., laysa 'is not', sawfa (future-tense marker) + The nunation endings -an -in -un are not pronounced. They are pronounced in adverbial accusative formations, e.g., تَقْرِيبًا 'almost, approximately', عَادَةً 'usually'. + The tāʾ marbūṭah ending ة is unpronounced, except in construct state nouns, where it sounds as t and in adverbial accusative constructions, e.g., عَادَةً 'usually', where the entire -tan is pronounced. + The masculine singular nisbah ending is pronounced and is unstressed, but plural and feminine singular forms, i.e. when followed by a suffix, still sound as . + Full endings, including case endings, occur when a clitic object or possessive suffix is added, e.g., 'us/our'. + +Informal short pronunciation +This is the pronunciation used by speakers of Modern Standard Arabic in extemporaneous speech, i.e. when producing new sentences rather than reading a prepared text. It is similar to formal short pronunciation except that the rules for dropping final vowels apply even when a clitic suffix is added. Basically, short-vowel case and mood endings are never pronounced and certain other changes occur that echo the corresponding colloquial pronunciations. Specifically: + All the rules for formal short pronunciation apply, except as follows. + The past tense singular endings written formally as -tu -ta -ti are pronounced -t -t -ti. But masculine is pronounced in full. + Unlike in formal short pronunciation, the rules for dropping or modifying final endings are also applied when a clitic object or possessive suffix is added (e.g., 'us/our'). If this produces a sequence of three consonants, then one of the following happens, depending on the speaker's native colloquial variety: + A short vowel (e.g., -i- or -ǝ-) is consistently added, either between the second and third or the first and second consonants. + Or, a short vowel is added only if an otherwise unpronounceable sequence occurs, typically due to a violation of the sonority hierarchy (e.g., -rtn- is pronounced as a three-consonant cluster, but -trn- needs to be broken up). + Or, a short vowel is never added, but consonants like r l m n occurring between two other consonants will be pronounced as a syllabic consonant, as in the English words "butter bottle bottom button". + When a doubled consonant occurs before another consonant, or finally, it is often shortened to a single consonant rather than a vowel added. Moroccan Arabic never shortens doubled consonants or inserts short vowels to break up clusters, instead tolerating arbitrary-length series of arbitrary consonants and hence Moroccan Arabic speakers are likely to follow the same rules in their pronunciation of Modern Standard Arabic. + The clitic suffixes themselves tend also to be changed, in a way that avoids many possible occurrences of three-consonant clusters. In particular, -ka -ki -hu generally sound as -ak -ik -uh. + Final long vowels are often shortened, merging with any short vowels that remain. + Depending on the level of formality, the speaker's education level, etc., various grammatical changes may occur in ways that echo the colloquial variants: + Any remaining case endings (e.g. masculine plural nominative -ūn vs. oblique -īn) will be leveled, with the oblique form used everywhere. In words like 'father' and 'brother' with special long-vowel case endings in the construct state, the nominative is used everywhere, hence 'father of', 'brother of'. + Feminine plural endings in verbs and clitic suffixes will often drop out, with the masculine plural endings used instead. If the speaker's native variety has feminine plural endings, they may be preserved, but will often be modified in the direction of the forms used in the speaker's native variety, e.g. -an instead of -na. + Dual endings will often drop out except on nouns and then used only for emphasis, similar to their use in the colloquial varieties. Elsewhere, the plural endings are used, or feminine singular, if appropriate. + +Colloquial varieties + +Vowels + +As mentioned above, many spoken dialects have a process of emphasis spreading, where the "emphasis" (pharyngealization) of emphatic consonants spreads forward and back through adjacent syllables, pharyngealizing all nearby consonants and triggering the back allophone in all nearby low vowels. The extent of emphasis spreading varies. For example, in Moroccan Arabic, it spreads as far as the first full vowel (i.e. sound derived from a long vowel or diphthong) on either side; in many Levantine dialects, it spreads indefinitely, but is blocked by any or ; while in Egyptian Arabic, it usually spreads throughout the entire word, including prefixes and suffixes. In Moroccan Arabic, also have emphatic allophones and , respectively. + +Unstressed short vowels, especially , are deleted in many contexts. Many sporadic examples of short vowel change have occurred (especially → and interchange ↔). Most Levantine dialects merge short /i u/ into in most contexts (all except directly before a single final consonant). In Moroccan Arabic, on the other hand, short triggers labialization of nearby consonants (especially velar consonants and uvular consonants), and then short /a i u/ all merge into , which is deleted in many contexts. (The labialization plus is sometimes interpreted as an underlying phoneme .) This essentially causes the wholesale loss of the short-long vowel distinction, with the original long vowels remaining as half-long , phonemically , which are used to represent both short and long vowels in borrowings from Literary Arabic. + +Most spoken dialects have monophthongized original to in most circumstances, including adjacent to emphatic consonants, while keeping them as the original diphthongs in others e.g. . In most of the Moroccan, Algerian and Tunisian (except Sahel and Southeastern) Arabic dialects, they have subsequently merged into original . + +Consonants +In most dialects, there may be more or fewer phonemes than those listed in the chart above. For example, is considered a native phoneme in most Arabic dialects except in Levantine dialects like Syrian or Lebanese where is pronounced and is pronounced . or () is considered a native phoneme in most dialects except in Egyptian and a number of Yemeni and Omani dialects where is pronounced . + + or and are distinguished in the dialects of Egypt, Sudan, the Levant and the Hejaz. They have merged as in most dialects of the Arabian Peninsula, Iraq and Tunisia and have merged as in Morocco and Algeria. The usage of non-native and depends on the usage of each speaker but they might be more prevalent in some dialects than others. The Iraqi and Gulf Arabic has the sound and writes it and with the Persian letters and , as in "plum"; "truffle". + +Early in the expansion of Arabic, the separate emphatic phonemes and coalesced into a single phoneme . Many dialects, such as Egyptian, Levantine, and much of the Maghreb, subsequently lost fricatives, converting into . Most dialects borrow "learned" words from the Standard language using the same pronunciation as for inherited words. Some dialects without interdental fricatives, particularly in Egypt and the Levant, render original in borrowed words as . + +Another key distinguishing mark of Arabic dialects is how they render the original velar and uvular plosives , (Proto-Semitic ), and : + retains its original pronunciation in widely scattered regions such as Yemen, Morocco, and urban areas of the Maghreb. It is pronounced as a glottal stop in several prestige dialects, such as those spoken in Cairo, Beirut and Damascus. It is rendered as a voiced velar plosive in the Persian Gulf, Upper Egypt, parts of the Maghreb, and less urban parts of the Levant (e.g. Jordan). In Iraqi Arabic it sometimes retains its original pronunciation and is sometimes rendered as a voiced velar plosive, depending on the word. Some traditionally Christian villages in rural areas of the Levant render the sound as , as do Shii Bahrainis. In some Gulf dialects, it is palatalized to or . It is pronounced as a voiced uvular constrictive in Sudanese Arabic. Many dialects with a modified pronunciation for maintain the pronunciation in certain words (often with religious or educational overtones) borrowed from the Classical language. + is pronounced as an affricate in Iraq and much of the Arabian Peninsula. It is pronounced in most of North Egypt and parts of Yemen and Oman, in Morocco, Tunisia, and the Levant, and , in most words in much of the Persian Gulf. + usually retains its original pronunciation but is palatalized to in many words in Israel and the Palestinian Territories, Iraq, and countries in the eastern part of the Arabian Peninsula. Often a distinction is made between the suffixes ('you', masc.) and ('you', fem.), which become and , respectively. In Sana'a, Omani, and Bahrani is pronounced . + +Pharyngealization of the emphatic consonants tends to weaken in many of the spoken varieties, and to spread from emphatic consonants to nearby sounds. The "emphatic" allophone automatically triggers pharyngealization of adjacent sounds in many dialects. As a result, it may be difficult or impossible to determine whether a given coronal consonant is phonemically emphatic or not, especially in dialects with long-distance emphasis spreading. A notable exception is the sounds vs. in Moroccan Arabic, because the former is pronounced as an affricate but the latter is not. + +Grammar + +Literary Arabic + +As in other Semitic languages, Arabic has a complex and unusual morphology, i.e. method of constructing words from a basic root. Arabic has a nonconcatenative "root-and-pattern" morphology: A root consists of a set of bare consonants (usually three), which are fitted into a discontinuous pattern to form words. For example, the word for 'I wrote' is constructed by combining the root 'write' with the pattern 'I Xed' to form 'I wrote'. + +Other verbs meaning 'I Xed' will typically have the same pattern but with different consonants, e.g. 'I read', 'I ate', 'I went', although other patterns are possible, e.g. 'I drank', 'I said', 'I spoke', where the subpattern used to signal the past tense may change but the suffix is always used. + +From a single root , numerous words can be formed by applying different patterns: + 'I wrote' + 'I had (something) written' + 'I corresponded (with someone)' + 'I dictated' + 'I subscribed' + 'we corresponded with each other' + 'I write' + 'I have (something) written' + 'I correspond (with someone)' + 'I dictate' + 'I subscribe' + 'we correspond each other' + 'it was written' + 'it was dictated' + 'written' + 'dictated' + 'book' + 'books' + 'writer' + 'writers' + 'desk, office' + 'library, bookshop' + etc. + +Nouns and adjectives +Nouns in Literary Arabic have three grammatical cases (nominative, accusative, and genitive [also used when the noun is governed by a preposition]); three numbers (singular, dual and plural); two genders (masculine and feminine); and three "states" (indefinite, definite, and construct). The cases of singular nouns, other than those that end in long ā, are indicated by suffixed short vowels (/-u/ for nominative, /-a/ for accusative, /-i/ for genitive). + +The feminine singular is often marked by /-at/, which is pronounced as /-ah/ before a pause. Plural is indicated either through endings (the sound plural) or internal modification (the broken plural). Definite nouns include all proper nouns, all nouns in "construct state" and all nouns which are prefixed by the definite article /al-/. Indefinite singular nouns, other than those that end in long ā, add a final /-n/ to the case-marking vowels, giving /-un/, /-an/ or /-in/, which is also referred to as nunation or tanwīn. + +Adjectives in Literary Arabic are marked for case, number, gender and state, as for nouns. The plural of all non-human nouns is always combined with a singular feminine adjective, which takes the /-at/ suffix. + +Pronouns in Literary Arabic are marked for person, number and gender. There are two varieties, independent pronouns and enclitics. Enclitic pronouns are attached to the end of a verb, noun or preposition and indicate verbal and prepositional objects or possession of nouns. The first-person singular pronoun has a different enclitic form used for verbs ( /-nī/) and for nouns or prepositions ( /-ī/ after consonants, /-ya/ after vowels). + +Nouns, verbs, pronouns and adjectives agree with each other in all respects. Non-human plural nouns are grammatically considered to be feminine singular. A verb in a verb-initial sentence is marked as singular regardless of its semantic number when the subject of the verb is explicitly mentioned as a noun. Numerals between three and ten show "chiasmic" agreement, in that grammatically masculine numerals have feminine marking and vice versa. + +Verbs + +Verbs in Literary Arabic are marked for person (first, second, or third), gender, and number. They are conjugated in two major paradigms (past and non-past); two voices (active and passive); and six moods (indicative, imperative, subjunctive, jussive, shorter energetic and longer energetic), the fifth and sixth moods, the energetics, exist only in Classical Arabic but not in MSA. There are two participles, active and passive, and a verbal noun, but no infinitive. + +The past and non-past paradigms are sometimes termed perfective and imperfective, indicating the fact that they actually represent a combination of tense and aspect. The moods other than the indicative occur only in the non-past, and the future tense is signaled by prefixing or onto the non-past. The past and non-past differ in the form of the stem (e.g., past vs. non-past ), and use completely different sets of affixes for indicating person, number and gender: In the past, the person, number and gender are fused into a single suffixal morpheme, while in the non-past, a combination of prefixes (primarily encoding person) and suffixes (primarily encoding gender and number) are used. The passive voice uses the same person/number/gender affixes but changes the vowels of the stem. + +The following shows a paradigm of a regular Arabic verb, 'to write'. In Modern Standard, the energetic mood, in either long or short form, which have the same meaning, is almost never used. + +Derivation +Like other Semitic languages, and unlike most other languages, Arabic makes much more use of nonconcatenative morphology, applying many templates applied roots, to derive words than adding prefixes or suffixes to words. + +For verbs, a given root can occur in many different derived verb stems, of which there are about fifteen,, each with one or more characteristic meanings and each with its own templates for the past and non-past stems, active and passive participles, and verbal noun. These are referred to by Western scholars as "Form I", "Form II", and so on through "Form XV", although Forms XI to XV are rare. + +These stems encode grammatical functions such as the causative, intensive and reflexive. Stems sharing the same root consonants represent separate verbs, albeit often semantically related, and each is the basis for its own conjugational paradigm. As a result, these derived stems are part of the system of derivational morphology, not part of the inflectional system. + +Examples of the different verbs formed from the root 'write' (using 'red' for Form IX, which is limited to colors and physical defects): + +Form II is sometimes used to create transitive denominative verbs (verbs built from nouns); Form V is the equivalent used for intransitive denominatives. + +The associated participles and verbal nouns of a verb are the primary means of forming new lexical nouns in Arabic. This is similar to the process by which, for example, the English gerund "meeting" (similar to a verbal noun) has turned into a noun referring to a particular type of social, often work-related event where people gather together to have a "discussion" (another lexicalized verbal noun). Another fairly common means of forming nouns is through one of a limited number of patterns that can be applied directly to roots, such as the "nouns of location" in ma- (e.g. 'desk, office' < 'write', 'kitchen' < 'cook'). + +The only three genuine suffixes are as follows: + The feminine suffix -ah; variously derives terms for women from related terms for men, or more generally terms along the same lines as the corresponding masculine, e.g. 'library' (also a writing-related place, but different from , as above). + The nisbah suffix -iyy-. This suffix is extremely productive, and forms adjectives meaning "related to X". It corresponds to English adjectives in -ic, -al, -an, -y, -ist, etc. + The feminine nisbah suffix -iyyah. This is formed by adding the feminine suffix -ah onto nisba adjectives to form abstract nouns. For example, from the basic root 'share' can be derived the Form VIII verb 'to cooperate, participate', and in turn its verbal noun 'cooperation, participation' can be formed. This in turn can be made into a nisbah adjective 'socialist', from which an abstract noun 'socialism' can be derived. Other recent formations are 'republic' (lit. "public-ness", < 'multitude, general public'), and the Gaddafi-specific variation 'people's republic' (lit. "masses-ness", < 'the masses', pl. of , as above). + +Colloquial varieties + +The spoken dialects have lost the case distinctions and make only limited use of the dual (it occurs only on nouns and its use is no longer required in all circumstances). They have lost the mood distinctions other than imperative, but many have since gained new moods through the use of prefixes (most often /bi-/ for indicative vs. unmarked subjunctive). They have also mostly lost the indefinite "nunation" and the internal passive. + +The following is an example of a regular verb paradigm in Egyptian Arabic. + +Writing system + +The Arabic alphabet derives from the Aramaic through Nabatean, to which it bears a loose resemblance like that of Coptic or Cyrillic scripts to Greek script. Traditionally, there were several differences between the Western (North African) and Middle Eastern versions of the alphabet—in particular, the faʼ had a dot underneath and qaf a single dot above in the Maghreb, and the order of the letters was slightly different (at least when they were used as numerals). + +However, the old Maghrebi variant has been abandoned except for calligraphic purposes in the Maghreb itself, and remains in use mainly in the Quranic schools (zaouias) of West Africa. Arabic, like all other Semitic languages (except for the Latin-written Maltese, and the languages with the Ge'ez script), is written from right to left. There are several styles of scripts such as thuluth, muhaqqaq, tawqi, rayhan, and notably naskh, which is used in print and by computers, and ruqʻah, which is commonly used for correspondence. + +Originally Arabic was made up of only rasm without diacritical marks Later diacritical points (which in Arabic are referred to as nuqaṯ) were added (which allowed readers to distinguish between letters such as b, t, th, n and y). Finally signs known as Tashkil were used for short vowels known as harakat and other uses such as final postnasalized or long vowels. + +Calligraphy + +After Khalil ibn Ahmad al Farahidi finally fixed the Arabic script around 786, many styles were developed, both for the writing down of the Quran and other books, and for inscriptions on monuments as decoration. + +Arabic calligraphy has not fallen out of use as calligraphy has in the Western world, and is still considered by Arabs as a major art form; calligraphers are held in great esteem. Being cursive by nature, unlike the Latin script, Arabic script is used to write down a verse of the Quran, a hadith, or a proverb. The composition is often abstract, but sometimes the writing is shaped into an actual form such as that of an animal. One of the current masters of the genre is Hassan Massoudy. + +In modern times the intrinsically calligraphic nature of the written Arabic form is haunted by the thought that a typographic approach to the language, necessary for digitized unification, will not always accurately maintain meanings conveyed through calligraphy. + +Romanization + +There are a number of different standards for the romanization of Arabic, i.e. methods of accurately and efficiently representing Arabic with the Latin script. There are various conflicting motivations involved, which leads to multiple systems. Some are interested in transliteration, i.e. representing the spelling of Arabic, while others focus on transcription, i.e. representing the pronunciation of Arabic. (They differ in that, for example, the same letter is used to represent both a consonant, as in "you" or "yet", and a vowel, as in "me" or "eat".) + +Some systems, e.g. for scholarly use, are intended to accurately and unambiguously represent the phonemes of Arabic, generally making the phonetics more explicit than the original word in the Arabic script. These systems are heavily reliant on diacritical marks such as "š" for the sound equivalently written sh in English. Other systems (e.g. the Bahá'í orthography) are intended to help readers who are neither Arabic speakers nor linguists with intuitive pronunciation of Arabic names and phrases. + +These less "scientific" systems tend to avoid diacritics and use digraphs (like sh and kh). These are usually simpler to read, but sacrifice the definiteness of the scientific systems, and may lead to ambiguities, e.g. whether to interpret sh as a single sound, as in gash, or a combination of two sounds, as in gashouse. The ALA-LC romanization solves this problem by separating the two sounds with a prime symbol ( ′ ); e.g., as′hal 'easier'. + +During the last few decades and especially since the 1990s, Western-invented text communication technologies have become prevalent in the Arab world, such as personal computers, the World Wide Web, email, bulletin board systems, IRC, instant messaging and mobile phone text messaging. Most of these technologies originally had the ability to communicate using the Latin script only, and some of them still do not have the Arabic script as an optional feature. As a result, Arabic speaking users communicated in these technologies by transliterating the Arabic text using the Latin script, sometimes known as IM Arabic. + +To handle those Arabic letters that cannot be accurately represented using the Latin script, numerals and other characters were appropriated. For example, the numeral "3" may be used to represent the Arabic letter . There is no universal name for this type of transliteration, but some have named it Arabic Chat Alphabet. Other systems of transliteration exist, such as using dots or capitalization to represent the "emphatic" counterparts of certain consonants. For instance, using capitalization, the letter , may be represented by d. Its emphatic counterpart, , may be written as D. + +Numerals +In most of present-day North Africa, the Western Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) are used. However, in Egypt and Arabic-speaking countries to the east of it, the Eastern Arabic numerals ( – – – – – – – – – ) are in use. When representing a number in Arabic, the lowest-valued position is placed on the right, so the order of positions is the same as in left-to-right scripts. Sequences of digits such as telephone numbers are read from left to right, but numbers are spoken in the traditional Arabic fashion, with units and tens reversed from the modern English usage. For example, 24 is said "four and twenty" just like in the German language (vierundzwanzig) and Classical Hebrew, and 1975 is said "a thousand and nine-hundred and five and seventy" or, more eloquently, "a thousand and nine-hundred five seventy". + +Arabic alphabet and nationalism +There have been many instances of national movements to convert Arabic script into Latin script or to Romanize the language. Currently, the only Arabic variety to use Latin script is Maltese. + +Lebanon +The Beirut newspaper La Syrie pushed for the change from Arabic script to Latin letters in 1922. The major head of this movement was Louis Massignon, a French Orientalist, who brought his concern before the Arabic Language Academy in Damascus in 1928. Massignon's attempt at Romanization failed as the academy and population viewed the proposal as an attempt from the Western world to take over their country. Sa'id Afghani, a member of the academy, mentioned that the movement to Romanize the script was a Zionist plan to dominate Lebanon. Said Akl created a Latin-based alphabet for Lebanese and used it in a newspaper he founded, Lebnaan, as well as in some books he wrote. + +Egypt +After the period of colonialism in Egypt, Egyptians were looking for a way to reclaim and re-emphasize Egyptian culture. As a result, some Egyptians pushed for an Egyptianization of the Arabic language in which the formal Arabic and the colloquial Arabic would be combined into one language and the Latin alphabet would be used. There was also the idea of finding a way to use Hieroglyphics instead of the Latin alphabet, but this was seen as too complicated to use. + +A scholar, Salama Musa agreed with the idea of applying a Latin alphabet to Arabic, as he believed that would allow Egypt to have a closer relationship with the West. He also believed that Latin script was key to the success of Egypt as it would allow for more advances in science and technology. This change in alphabet, he believed, would solve the problems inherent with Arabic, such as a lack of written vowels and difficulties writing foreign words that made it difficult for non-native speakers to learn. Ahmad Lutfi As Sayid and Muhammad Azmi, two Egyptian intellectuals, agreed with Musa and supported the push for Romanization. + +The idea that Romanization was necessary for modernization and growth in Egypt continued with Abd Al-Aziz Fahmi in 1944. He was the chairman for the Writing and Grammar Committee for the Arabic Language Academy of Cairo. This effort failed as the Egyptian people felt a strong cultural tie to the Arabic alphabet. In particular, the older Egyptian generations believed that the Arabic alphabet had strong connections to Arab values and history, due to the long history of the Arabic alphabet (Shrivtiel, 189) in Muslim societies. + +See also + + Arabic Ontology + Arabic diglossia + Arabic language influence on the Spanish language +Arabic Language International Council + Arabic literature + Arabic–English Lexicon + Arabist + A Dictionary of Modern Written Arabic + Glossary of Islam + International Association of Arabic Dialectology + List of Arab newspapers + List of Arabic-language television channels + List of Arabic given names + List of arabophones + List of countries where Arabic is an official language + List of French words of Arabic origin + Replacement of loanwords in Turkish + +Notes + +References + +Citations + +Sources + + + + + + + + + + + + + + + + + + + + + Suileman, Yasir.

He is widely regarded as one of the most influential figures in the history of cinema. In a career spanning six decades, he directed over 50 feature films, many of which are still widely watched and studied today. Known as the "Master of Suspense", he became as well known as any of his actors thanks to his many interviews, his cameo roles in most of his films, and his hosting and producing the television anthology Alfred Hitchcock Presents (1955–65). His films garnered 46 Academy Award nominations, including six wins, although he never won the award for Best Director, despite five nominations. + +Hitchcock initially trained as a technical clerk and copywriter before entering the film industry in 1919 as a title card designer. His directorial debut was the British-German silent film The Pleasure Garden (1925). His first successful film, The Lodger: A Story of the London Fog (1927), helped to shape the thriller genre, and Blackmail (1929) was the first British "talkie". His thrillers The 39 Steps (1935) and The Lady Vanishes (1938) are ranked among the greatest British films of the 20th century. By 1939, he had international recognition and producer David O. Selznick persuaded him to move to Hollywood. A string of successful films followed, including Rebecca (1940), Foreign Correspondent (1940), Suspicion (1941), Shadow of a Doubt (1943) and Notorious (1946). Rebecca won the Academy Award for Best Picture, with Hitchcock nominated as Best Director. He also received Oscar nominations for Lifeboat (1944), Spellbound (1945), Rear Window (1954) and Psycho (1960). + +Hitchcock's other notable films include Rope (1948), Strangers on a Train (1951), Dial M for Murder (1954), To Catch a Thief (1955), The Trouble with Harry (1955), Vertigo (1958), North by Northwest (1959), The Birds (1963) and Marnie (1964), all of which were also financially successful and are highly regarded by film historians. Hitchcock made multiple films with some of the biggest stars in Hollywood, including four with Cary Grant, four with James Stewart, three with Ingrid Bergman and three consecutively with Grace Kelly. Hitchcock became an American citizen in 1955. + +In 2012, Hitchcock's psychological thriller Vertigo, starring Stewart, displaced Orson Welles' Citizen Kane (1941) as the British Film Institute's greatest film ever made based on its world-wide poll of hundreds of film critics. , nine of his films had been selected for preservation in the United States National Film Registry, including his personal favourite, Shadow of a Doubt (1943). He received the BAFTA Fellowship in 1971, the AFI Life Achievement Award in 1979, and was knighted in December of that year, four months before his death on 29 April 1980. + +Biography + +Early life: 1899–1919 + +Early childhood and education + +Alfred Joseph Hitchcock was born on 13 August 1899 in the flat above his parents' leased greengrocer's shop at 517 High Road in Leytonstone, which was then part of Essex (now on the outskirts of East London). He was the son of Emma Jane (née Whelan; 1863–1942) and William Edgar Hitchcock (1862–1914), and had an older brother named William Daniel (1890–1943) and an older sister named Ellen Kathleen (1892–1979) who used the nickname "Nellie". His parents were both Roman Catholics with partial Irish ancestry. His father was a greengrocer, as his grandfather had been. There was a large extended family, including uncle John Hitchcock with his five-bedroom Victorian house on Campion Road in Putney, complete with a maid, cook, chauffeur, and gardener. Every summer, his uncle rented a seaside house for the family in Cliftonville. Hitchcock said that he first became class-conscious there, noticing the differences between tourists and locals. + +Describing himself as a well-behaved boy — his father called him his "little lamb without a spot" — Hitchcock said he could not remember ever having had a playmate. One of his favourite stories for interviewers was about his father sending him to the local police station with a note when he was five; the policeman looked at the note and locked him in a cell for a few minutes, saying, "This is what we do to naughty boys." The experience left him with a lifelong phobia of law enforcement, and he told Tom Snyder in 1973 that he was "scared stiff of anything ... to do with the law" and that he would refuse to even drive a car in case he got a parking ticket. When he was six, the family moved to Limehouse and leased two stores at 130 and 175 Salmon Lane, which they ran as a fish-and-chip shop and fishmongers' respectively; they lived above the former. Hitchcock attended his first school, the Howrah House Convent in Poplar, which he entered in 1907, at age 7. According to biographer Patrick McGilligan, he stayed at Howrah House for at most two years. He also attended a convent school, the Wode Street School "for the daughters of gentlemen and little boys" run by the Faithful Companions of Jesus. He then attended a primary school near his home and was for a short time a boarder at Salesian College in Battersea. + +The family moved again when Hitchcock was eleven, this time to Stepney, and on 5 October 1910 he was sent to St Ignatius College in Stamford Hill, a Jesuit grammar school with a reputation for discipline. As corporal punishment, the priests used a flat, hard, springy tool made of gutta-percha and known as a "ferula" which struck the whole palm; punishment was always at the end of the day, so the boys had to sit through classes anticipating the punishment if they had been written up for it. He later said that this is where he developed his sense of fear. The school register lists his year of birth as 1900 rather than 1899; biographer Donald Spoto says he was deliberately enrolled as a ten-year-old because he was a year behind with his schooling. While biographer Gene Adair reports that Hitchcock was "an average, or slightly above-average, pupil", Hitchcock said that he was "usually among the four or five at the top of the class"; at the end of his first year, his work in Latin, English, French and religious education was noted. He told Peter Bogdanovich: "The Jesuits taught me organisation, control and, to some degree, analysis." + +Hitchcock's favourite subject was geography and he became interested in maps and the timetables of trains, trams and buses; according to John Russell Taylor, he could recite all the stops on the Orient Express. He had a particular interest in London trams. An overwhelming majority of his films include rail or tram scenes, in particular The Lady Vanishes, Strangers on a Train and Number Seventeen. A clapperboard shows the number of the scene and the number of takes, and Hitchcock would often take the two numbers on the clapperboard and whisper the London tram route names. For example, if the clapperboard showed "Scene 23; Take 3", he would whisper "Woodford, Hampstead"Woodford being the terminus of the route 23 tram, and Hampstead the end of route 3. + +Henley's +Hitchcock told his parents that he wanted to be an engineer, and on 25 July 1913, he left St Ignatius and enrolled in night classes at the London County Council School of Engineering and Navigation in Poplar. In a book-length interview in 1962, he told François Truffaut that he had studied "mechanics, electricity, acoustics, and navigation". Then, on 12 December 1914, his father, who had been suffering from emphysema and kidney disease, died at the age of 52. To support himself and his mother — his older siblings had left home by then — Hitchcock took a job, for 15 shillings a week (£ in ), as a technical clerk at the Henley Telegraph and Cable Company in Blomfield Street, near London Wall. He continued night classes, this time in art history, painting, economics and political science. His older brother ran the family shops, while he and his mother continued to live in Salmon Lane. + +Hitchcock was too young to enlist when the First World War started in July 1914, and when he reached the required age of 18 in 1917, he received a C3 classification ("free from serious organic disease, able to stand service conditions in garrisons at home ... only suitable for sedentary work"). He joined a cadet regiment of the Royal Engineers and took part in theoretical briefings, weekend drills and exercises. John Russell Taylor wrote that, in one session of practical exercises in Hyde Park, Hitchcock was required to wear puttees. He could never master wrapping them around his legs, and they repeatedly fell down around his ankles. + +After the war, Hitchcock took an interest in creative writing. In June 1919, he became a founding editor and business manager of Henley's in-house publication, The Henley Telegraph (sixpence a copy), to which he submitted several short stories. Henley's promoted him to the advertising department, where he wrote copy and drew graphics for electric cable advertisements. He enjoyed the job and would stay late at the office to examine the proofs; he told Truffaut that this was his "first step toward cinema". He enjoyed watching films, especially American cinema, and from the age of 16 read the trade papers; he watched Charlie Chaplin, D. W. Griffith and Buster Keaton, and particularly liked Fritz Lang's Der müde Tod (1921). + +Inter-war career: 1919–1939 + +Famous Players–Lasky + +While still at Henley's, he read in a trade paper that Famous Players–Lasky, the production arm of Paramount Pictures, was opening a studio in London. They were planning to film The Sorrows of Satan by Marie Corelli, so he produced some drawings for the title cards and sent his work to the studio. They hired him, and in 1919 he began working for Islington Studios in Poole Street, Hoxton, as a title-card designer. + +Donald Spoto wrote that most of the staff were Americans with strict job specifications, but the English workers were encouraged to try their hand at anything, which meant that Hitchcock gained experience as a co-writer, art director and production manager on at least 18 silent films. The Times wrote in February 1922 about the studio's "special art title department under the supervision of Mr. A. J. Hitchcock". His work included Number 13 (1922), also known as Mrs. Peabody; it was cancelled because of financial problems - the few finished scenes are lost — and Always Tell Your Wife (1923), which he and Seymour Hicks finished together when Hicks was about to give up on it. Hicks wrote later about being helped by "a fat youth who was in charge of the property room ... [n]one other than Alfred Hitchcock". + +Gainsborough Pictures and work in Germany + +When Paramount pulled out of London in 1922, Hitchcock was hired as an assistant director by a new firm run in the same location by Michael Balcon, later known as Gainsborough Pictures. Hitchcock worked on Woman to Woman (1923) with the director Graham Cutts, designing the set, writing the script and producing. He said: "It was the first film that I had really got my hands onto." The editor and "script girl" on Woman to Woman was Alma Reville, his future wife. He also worked as an assistant to Cutts on The White Shadow (1924), The Passionate Adventure (1924), The Blackguard (1925) and The Prude's Fall (1925). The Blackguard was produced at the Babelsberg Studios in Potsdam, where Hitchcock watched part of the making of F. W. Murnau's The Last Laugh (1924). He was impressed with Murnau's work, and later used many of his techniques for the set design in his own productions. + +In the summer of 1925, Balcon asked Hitchcock to direct The Pleasure Garden (1925), starring Virginia Valli, a co-production of Gainsborough and the German firm Emelka at the Geiselgasteig studio near Munich. Reville, by then Hitchcock's fiancée, was assistant director-editor. Although the film was a commercial flop, Balcon liked Hitchcock's work; a Daily Express headline called him the "Young man with a master mind". Production of The Pleasure Garden encountered obstacles which Hitchcock would later learn from: on arrival to Brenner Pass, he failed to declare his film stock to customs and it was confiscated; one actress could not enter the water for a scene because she was on her period; budget overruns meant that he had to borrow money from the actors. Hitchcock also needed a translator to give instructions to the cast and crew. + +In Germany, Hitchcock observed the nuances of German cinema and filmmaking which had a big influence on him. When he was not working, he would visit Berlin's art galleries, concerts and museums. He would also meet with actors, writers and producers to build connections. Balcon asked him to direct a second film in Munich, The Mountain Eagle (1926), based on an original story titled Fear o' God. The film is lost, and Hitchcock called it "a very bad movie". A year later, Hitchcock wrote and directed The Ring; although the screenplay was credited solely to his name, Elliot Stannard assisted him with the writing. The Ring garnered positive reviews; the Bioscope critic called it "the most magnificent British film ever made". + +When he returned to England, Hitchcock was one of the early members of the London Film Society, newly formed in 1925. Through the Society, he became fascinated by the work by Soviet filmmakers: Dziga Vertov, Lev Kuleshov, Sergei Eisenstein and Vsevolod Pudovkin. He would also socialise with fellow English filmmakers Ivor Montagu, Adrian Brunel and Walter Mycroft. + +Hitchcock established himself as a name director with his first thriller, The Lodger: A Story of the London Fog (1927). The film concerns the hunt for a Jack the Ripper-style serial killer who, wearing a black cloak and carrying a black bag, is murdering young blonde women in London, and only on Tuesdays. A landlady suspects that her lodger is the killer, but he turns out to be innocent. Hitchcock had wanted the leading man to be guilty, or for the film at least to end ambiguously, but the star was Ivor Novello, a matinée idol, and the "star system" meant that Novello could not be the villain. Hitchcock told Truffaut: "You have to clearly spell it out in big letters: 'He is innocent.'" (He had the same problem years later with Cary Grant in Suspicion (1941).) Released in January 1927, The Lodger was a commercial and critical success in the UK. Upon its release, the trade journal Bioscope wrote: "It is possible that this film is the finest British production ever made". Hitchcock told Truffaut that the film was the first of his to be influenced by German Expressionism: "In truth, you might almost say that The Lodger was my first picture." He made his first cameo appearance in the film, sitting in a newsroom. + +Marriage + +On 2 December 1926, Hitchcock married the English screenwriter Alma Reville at the Brompton Oratory in South Kensington. The couple honeymooned in Paris, Lake Como and St. Moritz, before returning to London to live in a leased flat on the top two floors of 153 Cromwell Road, Kensington. Reville, who was born just hours after Hitchcock, converted from Protestantism to Catholicism, apparently at the insistence of Hitchcock's mother; she was baptised on 31 May 1927 and confirmed at Westminster Cathedral by Cardinal Francis Bourne on 5 June. + +In 1928, when they learned that Reville was pregnant, the Hitchcocks purchased "Winter's Grace", a Tudor farmhouse set in eleven acres on Stroud Lane, Shamley Green, Surrey, for £2,500. Their daughter and only child, Patricia Alma Hitchcock, was born on 7 July that year. Patricia died on 9 August 2021 at 93. + +Reville became her husband's closest collaborator; Charles Champlin wrote in 1982: "The Hitchcock touch had four hands, and two were Alma's." When Hitchcock accepted the AFI Life Achievement Award in 1979, he said that he wanted to mention "four people who have given me the most affection, appreciation and encouragement, and constant collaboration. The first of the four is a film editor, the second is a scriptwriter, the third is the mother of my daughter, Pat, and the fourth is as fine a cook as ever performed miracles in a domestic kitchen. And their names are Alma Reville." Reville wrote or co-wrote on many of Hitchcock's films, including Shadow of a Doubt, Suspicion and The 39 Steps. + +Early sound films + +Hitchcock began work on his tenth film, Blackmail (1929), when its production company, British International Pictures (BIP), converted its Elstree studios to sound. The film was the first British "talkie"; this followed the rapid development of sound films in the United States, from the use of brief sound segments in The Jazz Singer (1927) to the first full sound feature Lights of New York (1928). Blackmail began the Hitchcock tradition of using famous landmarks as a backdrop for suspense sequences, with the climax taking place on the dome of the British Museum. It also features one of his longest cameo appearances, which shows him being bothered by a small boy as he reads a book on the London Underground. In the PBS series The Men Who Made The Movies, Hitchcock explained how he used early sound recording as a special element of the film, stressing the word "knife" in a conversation with the woman suspected of murder. During this period, Hitchcock directed segments for a BIP revue, Elstree Calling (1930), and directed a short film, An Elastic Affair (1930), featuring two Film Weekly scholarship winners. An Elastic Affair is one of the lost films. + +In 1933, Hitchcock signed a multi-film contract with Gaumont-British, once again working for Michael Balcon. His first film for the company, The Man Who Knew Too Much (1934), was a success; his second, The 39 Steps (1935), was acclaimed in the UK, and gained him recognition in the United States. It also established the quintessential English "Hitchcock blonde" (Madeleine Carroll) as the template for his succession of ice-cold, elegant leading ladies. Screenwriter Robert Towne remarked: "It's not much of an exaggeration to say that all contemporary escapist entertainment begins with The 39 Steps". John Buchan, author of The Thirty-Nine Steps on which the film is loosely based, met with Hitchcock on set, and attended the high-profile premiere at the New Gallery Cinema in London. Upon viewing the film, the author said it had improved on the book. This film was one of the first to introduce the "MacGuffin" plot device, a term coined by the English screenwriter Angus MacPhail. The MacGuffin is an item or goal the protagonist is pursuing, one that otherwise has no narrative value; in The 39 Steps, the MacGuffin is a stolen set of design plans. + +Hitchcock released two spy thrillers in 1936. Sabotage was loosely based on Joseph Conrad's novel, The Secret Agent (1907), about a woman who discovers that her husband is a terrorist, and Secret Agent, based on two stories in Ashenden: Or the British Agent (1928) by W. Somerset Maugham. + +At this time, Hitchcock also became notorious for pranks against the cast and crew. These jokes ranged from simple and innocent to crazy and maniacal. For instance, he hosted a dinner party where he dyed all the food blue because he claimed there weren't enough blue foods. He also had a horse delivered to the dressing room of his friend, actor Gerald du Maurier. + +Hitchcock followed up with Young and Innocent in 1937, a crime thriller based on the 1936 novel A Shilling for Candles by Josephine Tey. Starring Nova Pilbeam and Derrick De Marney, the film was relatively enjoyable for the cast and crew to make. To meet distribution purposes in America, the film's runtime was cut and this included removal of one of Hitchcock's favourite scenes: a children's tea party which becomes menacing to the protagonists. + +Hitchcock's next major success was The Lady Vanishes (1938), "one of the greatest train movies from the genre's golden era", according to Philip French, in which Miss Froy (May Whitty), a British spy posing as a governess, disappears on a train journey through the fictional European country of Bandrika. The film saw Hitchcock receive the 1938 New York Film Critics Circle Award for Best Director. Benjamin Crisler of the New York Times wrote in June 1938: "Three unique and valuable institutions the British have that we in America have not: Magna Carta, the Tower Bridge and Alfred Hitchcock, the greatest director of screen melodramas in the world." The film was based on the novel The Wheel Spins (1936) written by Ethel Lina White. + +By 1938, Hitchcock was aware that he had reached his peak in Britain. He had received numerous offers from producers in the United States, but he turned them all down because he disliked the contractual obligations or thought the projects were repellent. However, producer David O. Selznick offered him a concrete proposal to make a film based on the sinking of , which was eventually shelved, but Selznick persuaded Hitchcock to come to Hollywood. In July 1938, Hitchcock flew to New York, and found that he was already a celebrity; he was featured in magazines and gave interviews to radio stations. In Hollywood, Hitchcock met Selznick for the first time. Selznick offered him a four-film contract, approximately $40,000 for each picture (). + +Early Hollywood years: 1939–1945 + +Selznick contract +Selznick signed Hitchcock to a seven-year contract beginning in April 1939, and the Hitchcocks moved to Hollywood. The Hitchcocks lived in a spacious flat on Wilshire Boulevard, and slowly acclimatised themselves to the Los Angeles area. He and his wife Alma kept a low profile, and were not interested in attending parties or being celebrities. Hitchcock discovered his taste for fine food in West Hollywood, but still carried on his way of life from England. He was impressed with Hollywood's filmmaking culture, expansive budgets and efficiency, compared to the limits that he had often faced in Britain. In June that year, Life called him the "greatest master of melodrama in screen history". + +Although Hitchcock and Selznick respected each other, their working arrangements were sometimes difficult. Selznick suffered from constant financial problems, and Hitchcock was often unhappy about Selznick's creative control and interference over his films. Selznick was also displeased with Hitchcock's method of shooting just what was in the script, and nothing more, which meant that the film could not be cut and remade differently at a later time. As well as complaining about Hitchcock's "goddamn jigsaw cutting", their personalities were mismatched: Hitchcock was reserved whereas Selznick was flamboyant. Eventually, Selznick generously lent Hitchcock to the larger film studios. Selznick made only a few films each year, as did fellow independent producer Samuel Goldwyn, so he did not always have projects for Hitchcock to direct. Goldwyn had also negotiated with Hitchcock on a possible contract, only to be outbid by Selznick. In a later interview, Hitchcock said: "[Selznick] was the Big Producer. ... Producer was king. The most flattering thing Mr. Selznick ever said about me—and it shows you the amount of control—he said I was the 'only director' he'd 'trust with a film'." + +Hitchcock approached American cinema cautiously; his first American film was set in England in which the "Americanness" of the characters was incidental: Rebecca (1940) was set in a Hollywood version of England's Cornwall and based on a novel by English novelist Daphne du Maurier. Selznick insisted on a faithful adaptation of the book, and disagreed with Hitchcock with the use of humour. The film, starring Laurence Olivier and Joan Fontaine, concerns an unnamed naïve young woman who marries a widowed aristocrat. She lives in his large English country house, and struggles with the lingering reputation of his elegant and worldly first wife Rebecca, who died under mysterious circumstances. The film won Best Picture at the 13th Academy Awards; the statuette was given to producer Selznick. Hitchcock received his first nomination for Best Director, his first of five such nominations. + +Hitchcock's second American film was the thriller Foreign Correspondent (1940), set in Europe, based on Vincent Sheean's book Personal History (1935) and produced by Walter Wanger. It was nominated for Best Picture that year. Hitchcock felt uneasy living and working in Hollywood while Britain was at war; his concern resulted in a film that overtly supported the British war effort. Filmed in 1939, it was inspired by the rapidly changing events in Europe, as covered by an American newspaper reporter played by Joel McCrea. By mixing footage of European scenes with scenes filmed on a Hollywood backlot, the film avoided direct references to Nazism, Nazi Germany and Germans, to comply with the Motion Picture Production Code at the time. + +Early war years +In September 1940, the Hitchcocks bought the Cornwall Ranch near Scotts Valley, California, in the Santa Cruz Mountains. Their primary residence was an English-style home in Bel Air, purchased in 1942. Hitchcock's films were diverse during this period, ranging from the romantic comedy Mr. & Mrs. Smith (1941) to the bleak film noir Shadow of a Doubt (1943). + +Suspicion (1941) marked Hitchcock's first film as a producer and director. It is set in England; Hitchcock used the north coast of Santa Cruz for the English coastline sequence. The film is the first of four in which Cary Grant was cast by Hitchcock, and it is one of the rare occasions that Grant plays a sinister character. Grant plays Johnnie Aysgarth, an English conman whose actions raise suspicion and anxiety in his shy young English wife, Lina McLaidlaw (Joan Fontaine). In one scene, Hitchcock placed a light inside a glass of milk, perhaps poisoned, that Grant is bringing to his wife; the light ensures that the audience's attention is on the glass. Grant's character is actually a killer, as per written in the book, Before the Fact by Francis Iles, but the studio felt that Grant's image would be tarnished by that. Hitchcock therefore settled for an ambiguous finale, although he would have preferred to end with the wife's murder. Fontaine won Best Actress for her performance. + +Saboteur (1942) is the first of two films that Hitchcock made for Universal Studios during the decade. Hitchcock wanted Gary Cooper and Barbara Stanwyck or Henry Fonda and Gene Tierney to star, but was forced by Universal to use Universal contract player Robert Cummings and Priscilla Lane, a freelancer who signed a one-picture deal with the studio, both known for their work in comedies and light dramas. The story depicts a confrontation between a suspected saboteur (Cummings) and a real saboteur (Norman Lloyd) atop the Statue of Liberty. Hitchcock took a three-day tour of New York City to scout for Saboteurs filming locations. He also directed Have You Heard? (1942), a photographic dramatisation for Life magazine of the dangers of rumours during wartime. In 1943, he wrote a mystery story for Look, "The Murder of Monty Woolley", a sequence of captioned photographs inviting the reader to find clues to the murderer's identity; Hitchcock cast the performers as themselves, such as Woolley, Doris Merrick and make-up man Guy Pearce. + +Back in England, Hitchcock's mother Emma was severely ill; she died on 26 September 1942 at age 79. Hitchcock never spoke publicly about his mother, but his assistant said that he admired her. Four months later, on 4 January 1943, his brother William died of an overdose at age 52. Hitchcock was not very close to William, but his death made Hitchcock conscious about his own eating and drinking habits. He was overweight and suffering from back aches. His New Year's resolution in 1943 was to take his diet seriously with the help of a physician. In January that year, Shadow of a Doubt was released, which Hitchcock had fond memories of making. In the film, Charlotte "Charlie" Newton (Teresa Wright) suspects her beloved uncle Charlie Oakley (Joseph Cotten) of being a serial killer. Hitchcock filmed extensively on location, this time in the Northern California city of Santa Rosa. + +At 20th Century Fox, Hitchcock approached John Steinbeck with an idea for a film, which recorded the experiences of the survivors of a German U-boat attack. Steinbeck began work on the script for what would become Lifeboat (1944). However, Steinbeck was unhappy with the film and asked that his name be removed from the credits, to no avail. The idea was rewritten as a short story by Harry Sylvester and published in Collier's in 1943. The action sequences were shot in a small boat in the studio water tank. The locale posed problems for Hitchcock's traditional cameo appearance; it was solved by having Hitchcock's image appear in a newspaper that William Bendix is reading in the boat, showing the director in a before-and-after advertisement for "Reduco-Obesity Slayer". He told Truffaut in 1962: + +Hitchcock's typical dinner before his weight loss had been a roast chicken, boiled ham, potatoes, bread, vegetables, relishes, salad, dessert, a bottle of wine and some brandy. To lose weight, his diet consisted of black coffee for breakfast and lunch, and steak and salad for dinner, but it was hard to maintain; Donald Spoto wrote that his weight fluctuated considerably over the next 40 years. At the end of 1943, despite the weight loss, the Occidental Insurance Company of Los Angeles refused his application for life insurance. + +Wartime non-fiction films + +Hitchcock returned to the UK for an extended visit in late 1943 and early 1944. While there he made two short propaganda films, Bon Voyage (1944) and Aventure Malgache (1944), for the Ministry of Information. In June and July 1945, Hitchcock served as "treatment advisor" on a Holocaust documentary that used Allied Forces footage of the liberation of Nazi concentration camps. The film was assembled in London and produced by Sidney Bernstein of the Ministry of Information, who brought Hitchcock (a friend of his) on board. It was originally intended to be broadcast to the Germans, but the British government deemed it too traumatic to be shown to a shocked post-war population. Instead, it was transferred in 1952 from the British War Office film vaults to London's Imperial War Museum and remained unreleased until 1985, when an edited version was broadcast as an episode of PBS Frontline, under the title the Imperial War Museum had given it: Memory of the Camps. The full-length version of the film, German Concentration Camps Factual Survey, was restored in 2014 by scholars at the Imperial War Museum. + +Post-war Hollywood years: 1945–1953 + +Later Selznick films + +Hitchcock worked for David Selznick again when he directed Spellbound (1945), which explores psychoanalysis and features a dream sequence designed by Salvador Dalí. The dream sequence as it appears in the film is ten minutes shorter than was originally envisioned; Selznick edited it to make it "play" more effectively. Gregory Peck plays amnesiac Dr. Anthony Edwardes under the treatment of analyst Dr. Peterson (Ingrid Bergman), who falls in love with him while trying to unlock his repressed past. Two point-of-view shots were achieved by building a large wooden hand (which would appear to belong to the character whose point of view the camera took) and out-sized props for it to hold: a bucket-sized glass of milk and a large wooden gun. For added novelty and impact, the climactic gunshot was hand-coloured red on some copies of the black-and-white film. The original musical score by Miklós Rózsa makes use of the theremin, and some of it was later adapted by the composer into Rozsa's Piano Concerto Op. 31 (1967) for piano and orchestra. + +The spy film Notorious followed next in 1946. Hitchcock told François Truffaut that Selznick sold him, Ingrid Bergman, Cary Grant and Ben Hecht's screenplay, to RKO Radio Pictures as a "package" for $500,000 (equivalent to $ million in ) because of cost overruns on Selznick's Duel in the Sun (1946). Notorious stars Bergman and Grant, both Hitchcock collaborators, and features a plot about Nazis, uranium and South America. His prescient use of uranium as a plot device led to him being briefly placed under surveillance by the Federal Bureau of Investigation. According to Patrick McGilligan, in or around March 1945, Hitchcock and Hecht consulted Robert Millikan of the California Institute of Technology about the development of a uranium bomb. Selznick complained that the notion was "science fiction", only to be confronted by the news of the detonation of two atomic bombs on Hiroshima and Nagasaki in Japan in August 1945. + +Transatlantic Pictures + +Hitchcock formed an independent production company, Transatlantic Pictures, with his friend Sidney Bernstein. He made two films with Transatlantic, one of which was his first colour film. With Rope (1948), Hitchcock experimented with marshalling suspense in a confined environment, as he had done earlier with Lifeboat. The film appears as a very limited number of continuous shots, but it was actually shot in 10 ranging from to 10 minutes each; a 10-minute length of film was the most that a camera's film magazine could hold at the time. Some transitions between reels were hidden by having a dark object fill the entire screen for a moment. Hitchcock used those points to hide the cut, and began the next take with the camera in the same place. The film features James Stewart in the leading role, and was the first of four films that Stewart made with Hitchcock. It was inspired by the Leopold and Loeb case of the 1920s. Critical response at the time was mixed. + +Under Capricorn (1949), set in 19th-century Australia, also uses the short-lived technique of long takes, but to a more limited extent. He again used Technicolor in this production, then returned to black-and-white for several years. Transatlantic Pictures became inactive after the last two films. Hitchcock filmed Stage Fright (1950) at Elstree Studios in England, where he had worked during his British International Pictures contract many years before. He paired one of Warner Bros.' most popular stars, Jane Wyman, with the expatriate German actor Marlene Dietrich and used several prominent British actors, including Michael Wilding, Richard Todd and Alastair Sim. This was Hitchcock's first proper production for Warner Bros., which had distributed Rope and Under Capricorn, because Transatlantic Pictures was experiencing financial difficulties. + +His thriller Strangers on a Train (1951) was based on the novel of the same name by Patricia Highsmith. Hitchcock combined many elements from his preceding films. He approached Dashiell Hammett to write the dialogue, but Raymond Chandler took over, then left over disagreements with the director. In the film, two men casually meet, one of whom speculates on a foolproof method to murder; he suggests that two people, each wishing to do away with someone, should each perform the other's murder. Farley Granger's role was as the innocent victim of the scheme, while Robert Walker, previously known for "boy-next-door" roles, played the villain. I Confess (1953) was set in Quebec with Montgomery Clift as a Catholic priest. + +Peak years: 1954–1964 + +Dial M for Murder and Rear Window + +I Confess was followed by three colour films starring Grace Kelly: Dial M for Murder (1954), Rear Window (1954) and To Catch a Thief (1955). In Dial M for Murder, Ray Milland plays the villain who tries to murder his unfaithful wife (Kelly) for her money. She kills the hired assassin in self-defence, so Milland manipulates the evidence to make it look like murder. Her lover, Mark Halliday (Robert Cummings), and Police Inspector Hubbard (John Williams) save her from execution. Hitchcock experimented with 3D cinematography for Dial M for Murder. + +Hitchcock moved to Paramount Pictures and filmed Rear Window (1954), starring James Stewart and Grace Kelly, as well as Thelma Ritter and Raymond Burr. Stewart's character is a photographer named Jeff (based on Robert Capa) who must temporarily use a wheelchair. Out of boredom, he begins observing his neighbours across the courtyard, then becomes convinced that one of them (Raymond Burr) has murdered his wife. Jeff eventually manages to convince his policeman buddy (Wendell Corey) and his girlfriend (Kelly). As with Lifeboat and Rope, the principal characters are depicted in confined or cramped quarters, in this case Stewart's studio apartment. Hitchcock uses close-ups of Stewart's face to show his character's reactions, "from the comic voyeurism directed at his neighbours to his helpless terror watching Kelly and Burr in the villain's apartment". + +Alfred Hitchcock Presents + +From 1955 to 1965, Hitchcock was the host of the television series Alfred Hitchcock Presents. With his droll delivery, gallows humour and iconic image, the series made Hitchcock a celebrity. The title-sequence of the show pictured a minimalist caricature of his profile (he drew it himself; it is composed of only nine strokes), which his real silhouette then filled. The series theme tune was Funeral March of a Marionette by the French composer Charles Gounod (1818–1893). + +His introductions always included some sort of wry humour, such as the description of a recent multi-person execution hampered by having only one electric chair, while two are shown with a sign "Two chairs—no waiting!" He directed 18 episodes of the series, which aired from 1955 to 1965. It became The Alfred Hitchcock Hour in 1962, and NBC broadcast the final episode on 10 May 1965. In the 1980s, a new version of Alfred Hitchcock Presents was produced for television, making use of Hitchcock's original introductions in a colourised form. + +Hitchcock's success in television spawned a set of short-story collections in his name; these included Alfred Hitchcock's Anthology, Stories They Wouldn't Let Me Do on TV, and Tales My Mother Never Told Me. In 1956, HSD Publications also licensed the director's name to create Alfred Hitchcock's Mystery Magazine, a monthly digest specialising in crime and detective fiction. Hitchcock's television series were very profitable, and his foreign-language versions of books were bringing revenues of up to $100,000 a year (). + +From To Catch a Thief to Vertigo +In 1955, Hitchcock became a United States citizen. In the same year, his third Grace Kelly film, To Catch a Thief, was released; it is set in the French Riviera, and stars Kelly and Cary Grant. Grant plays retired thief John Robie, who becomes the prime suspect for a spate of robberies in the Riviera. A thrill-seeking American heiress played by Kelly surmises his true identity and tries to seduce him. "Despite the obvious age disparity between Grant and Kelly and a lightweight plot, the witty script (loaded with double entendres) and the good-natured acting proved a commercial success." It was Hitchcock's last film with Kelly; she married Prince Rainier of Monaco in 1956, and ended her film career afterward. Hitchcock then remade his own 1934 film The Man Who Knew Too Much in 1956. This time, the film starred James Stewart and Doris Day, who sang the theme song "Que Sera, Sera", which won the Academy Award for Best Original Song and became a big hit. They play a couple whose son is kidnapped to prevent them from interfering with an assassination. As in the 1934 film, the climax takes place at the Royal Albert Hall. + +The Wrong Man (1956), Hitchcock's final film for Warner Bros., is a low-key black-and-white production based on a real-life case of mistaken identity reported in Life magazine in 1953. This was the only film of Hitchcock to star Henry Fonda, playing a Stork Club musician mistaken for a liquor store thief, who is arrested and tried for robbery while his wife (Vera Miles) emotionally collapses under the strain. Hitchcock told Truffaut that his lifelong fear of the police attracted him to the subject and was embedded in many scenes. + +While directing episodes for Alfred Hitchcock Presents during the summer of 1957, Hitchcock was admitted to hospital for hernia and gallstones, and had to have his gallbladder removed. Following a successful surgery, he immediately returned to work to prepare for his next project. Vertigo (1958) again starred James Stewart, with Kim Novak and Barbara Bel Geddes. He had wanted Vera Miles to play the lead, but she was pregnant. He told Oriana Fallaci: "I was offering her a big part, the chance to become a beautiful sophisticated blonde, a real actress. We'd have spent a heap of dollars on it, and she has the bad taste to get pregnant. I hate pregnant women, because then they have children." + +In Vertigo, Stewart plays Scottie, a former police investigator suffering from acrophobia, who becomes obsessed with a woman he has been hired to shadow (Novak). Scottie's obsession leads to tragedy, and this time Hitchcock did not opt for a happy ending. Some critics, including Donald Spoto and Roger Ebert, agree that Vertigo is the director's most personal and revealing film, dealing with the Pygmalion-like obsessions of a man who moulds a woman into the person he desires. Vertigo explores more frankly and at greater length his interest in the relation between sex and death, than any other work in his filmography. + +Vertigo contains a camera technique developed by Irmin Roberts, commonly referred to as a dolly zoom, which has been copied by many filmmakers. The film premiered at the San Sebastián International Film Festival, and Hitchcock won the Silver Seashell prize. Vertigo is considered a classic, but it attracted mixed reviews and poor box-office receipts at the time; the critic from Variety opined that the film was "too slow and too long". Bosley Crowther of the New York Times thought it was "devilishly far-fetched", but praised the cast performances and Hitchcock's direction. The picture was also the last collaboration between Stewart and Hitchcock. In the 2002 Sight & Sound polls, it ranked just behind Citizen Kane (1941); ten years later, in the same magazine, critics chose it as the best film ever made. + +North by Northwest and Psycho + +After Vertigo, the rest of 1958 was a difficult year for Hitchcock. During pre-production of North by Northwest (1959), which was a "slow" and "agonising" process, his wife Alma was diagnosed with cancer. While she was in hospital, Hitchcock kept himself occupied with his television work and would visit her every day. Alma underwent surgery and made a full recovery, but it caused Hitchcock to imagine, for the first time, life without her. + +Hitchcock followed up with three more successful films, which are also recognised as among his best: North by Northwest, Psycho (1960) and The Birds (1963). In North by Northwest, Cary Grant portrays Roger Thornhill, a Madison Avenue advertising executive who is mistaken for a government secret agent. He is pursued across the United States by enemy agents, including Eve Kendall (Eva Marie Saint). At first, Thornhill believes Kendall is helping him, but then realises that she is an enemy agent; he later learns that she is working undercover for the CIA. During its opening two-week run at Radio City Music Hall, the film grossed $404,056 (equivalent to $ million in ), setting a non-holiday gross record for that theatre. Time magazine called the film "smoothly troweled and thoroughly entertaining". + +Psycho (1960) is arguably Hitchcock's best-known film. Based on Robert Bloch's 1959 novel Psycho, which was inspired by the case of Ed Gein, the film was produced on a tight budget of $800,000 (equivalent to $ million in ) and shot in black-and-white on a spare set using crew members from Alfred Hitchcock Presents. The unprecedented violence of the shower scene, the early death of the heroine, and the innocent lives extinguished by a disturbed murderer became the hallmarks of a new horror-film genre. The film proved popular with audiences, with lines stretching outside theatres as viewers waited for the next showing. It broke box-office records in the United Kingdom, France, South America, the United States and Canada, and was a moderate success in Australia for a brief period. + +Psycho was the most profitable of Hitchcock's career, and he personally earned in excess of $15 million (equivalent to $ million in ). He subsequently swapped his rights to Psycho and his TV anthology for 150,000 shares of MCA, making him the third largest shareholder and his own boss at Universal, in theory at least, although that did not stop studio interference. Following the first film, Psycho became an American horror franchise: Psycho II, Psycho III, Bates Motel, Psycho IV: The Beginning and a colour 1998 remake of the original. + +Truffaut interview + +On 13 August 1962, Hitchcock's 63rd birthday, the French director François Truffaut began a 50-hour interview of Hitchcock, filmed over eight days at Universal Studios, during which Hitchcock agreed to answer 500 questions. It took four years to transcribe the tapes and organise the images; it was published as a book in 1967, which Truffaut nicknamed the "Hitchbook". The audio tapes were used as the basis of a documentary in 2015. Truffaut sought the interview because it was clear to him that Hitchcock was not simply the mass-market entertainer the American media made him out to be. It was obvious from his films, Truffaut wrote, that Hitchcock had "given more thought to the potential of his art than any of his colleagues". He compared the interview to "Oedipus' consultation of the oracle". + +The Birds + +The film scholar Peter William Evans wrote that The Birds (1963) and Marnie (1964) are regarded as "undisputed masterpieces". Hitchcock had intended to film Marnie first, and in March 1962 it was announced that Grace Kelly, Princess Grace of Monaco since 1956, would come out of retirement to star in it. When Kelly asked Hitchcock to postpone Marnie until 1963 or 1964, he recruited Evan Hunter, author of The Blackboard Jungle (1954), to develop a screenplay based on a Daphne du Maurier short story, "The Birds" (1952), which Hitchcock had republished in his My Favorites in Suspense (1959). He hired Tippi Hedren to play the lead role. It was her first role; she had been a model in New York when Hitchcock saw her, in October 1961, in an NBC television advert for Sego, a diet drink: "I signed her because she is a classic beauty. Movies don't have them any more. Grace Kelly was the last." He insisted, without explanation, that her first name be written in single quotation marks: 'Tippi'. + +In The Birds, Melanie Daniels, a young socialite, meets lawyer Mitch Brenner (Rod Taylor) in a bird shop; Jessica Tandy plays his possessive mother. Hedren visits him in Bodega Bay (where The Birds was filmed) carrying a pair of lovebirds as a gift. Suddenly waves of birds start gathering, watching, and attacking. The question: "What do the birds want?" is left unanswered. Hitchcock made the film with equipment from the Revue Studio, which made Alfred Hitchcock Presents. He said it was his most technically challenging film, using a combination of trained and mechanical birds against a backdrop of wild ones. Every shot was sketched in advance. + +An HBO/BBC television film, The Girl (2012), depicted Hedren's experiences on set; she said that Hitchcock became obsessed with her and sexually harassed her. He reportedly isolated her from the rest of the crew, had her followed, whispered obscenities to her, had her handwriting analysed and had a ramp built from his private office directly into her trailer. Diane Baker, her co-star in Marnie, said: "[N]othing could have been more horrible for me than to arrive on that movie set and to see her being treated the way she was." While filming the attack scene in the attic — which took a week to film — she was placed in a caged room while two men wearing elbow-length protective gloves threw live birds at her. Toward the end of the week, to stop the birds' flying away from her too soon, one leg of each bird was attached by nylon thread to elastic bands sewn inside her clothes. She broke down after a bird cut her lower eyelid, and filming was halted on doctor's orders. + +Marnie + +In June 1962, Grace Kelly announced that she had decided against appearing in Marnie (1964). Hedren had signed an exclusive seven-year, $500-a-week contract with Hitchcock in October 1961, and he decided to cast her in the lead role opposite Sean Connery. In 2016, describing Hedren's performance as "one of the greatest in the history of cinema", Richard Brody called the film a "story of sexual violence" inflicted on the character played by Hedren: "The film is, to put it simply, sick, and it's so because Hitchcock was sick. He suffered all his life from furious sexual desire, suffered from the lack of its gratification, suffered from the inability to transform fantasy into reality, and then went ahead and did so virtually, by way of his art." A 1964 New York Times review called it Hitchcock's "most disappointing film in years", citing Hedren's and Connery's lack of experience, an amateurish script and "glaringly fake cardboard backdrops". + +In the film, Marnie Edgar (Hedren) steals $10,000 from her employer and goes on the run. She applies for a job at Mark Rutland's (Connery) company in Philadelphia and steals from there too. Earlier, she is shown having a panic attack during a thunderstorm and fearing the colour red. Mark tracks her down and blackmails her into marrying him. She explains that she does not want to be touched, but during the "honeymoon", Mark rapes her. Marnie and Mark discover that Marnie's mother had been a prostitute when Marnie was a child, and that, while the mother was fighting with a client during a thunderstorm — the mother believed the client had tried to molest Marnie — Marnie had killed the client to save her mother. Cured of her fears when she remembers what happened, she decides to stay with Mark. + +Hitchcock told cinematographer Robert Burks that the camera had to be placed as close as possible to Hedren when he filmed her face. Evan Hunter, the screenwriter of The Birds who was writing Marnie too, explained to Hitchcock that, if Mark loved Marnie, he would comfort her, not rape her. Hitchcock reportedly replied: "Evan, when he sticks it in her, I want that camera right on her face!" When Hunter submitted two versions of the script, one without the rape scene, Hitchcock replaced him with Jay Presson Allen. + +Later years: 1966–1980 + +Final films +Failing health reduced Hitchcock's output during the last two decades of his life. Biographer Stephen Rebello claimed Universal imposed two films on him, Torn Curtain (1966) and Topaz (1969), the latter of which is based on a Leon Uris novel, partly set in Cuba. Both were spy thrillers with Cold War-related themes. Torn Curtain, with Paul Newman and Julie Andrews, precipitated the bitter end of the twelve-year collaboration between Hitchcock and composer Bernard Herrmann. Hitchcock was unhappy with Herrmann's score and replaced him with John Addison, Jay Livingston and Ray Evans. Upon release, Torn Curtain was a box office disappointment, and Topaz was disliked by both critics and the studio. + +Hitchcock returned to Britain to make his penultimate film, Frenzy (1972), based on the novel Goodbye Piccadilly, Farewell Leicester Square (1966). After two espionage films, the plot marked a return to the murder-thriller genre. Richard Blaney (Jon Finch), a volatile barman with a history of explosive anger, becomes the prime suspect in the investigation into the "Necktie Murders", which are actually committed by his friend Bob Rusk (Barry Foster). This time, Hitchcock makes the victim and villain kindreds, rather than opposites, as in Strangers on a Train. + +In Frenzy, Hitchcock allowed nudity for the first time. Two scenes show naked women, one of whom is being raped and strangled; Donald Spoto called the latter "one of the most repellent examples of a detailed murder in the history of film". Both actors, Barbara Leigh-Hunt and Anna Massey, refused to do the scenes, so models were used instead. Biographers have noted that Hitchcock had always pushed the limits of film censorship, often managing to fool Joseph Breen, the head of the Motion Picture Production Code. Hitchcock would add subtle hints of improprieties forbidden by censorship until the mid-1960s. Yet, Patrick McGilligan wrote that Breen and others often realised that Hitchcock was inserting such material and were actually amused, as well as alarmed by Hitchcock's "inescapable inferences". + +Family Plot (1976) was Hitchcock's last film. It relates the escapades of "Madam" Blanche Tyler, played by Barbara Harris, a fraudulent spiritualist, and her taxi-driver lover Bruce Dern, making a living from her phony powers. While Family Plot was based on the Victor Canning novel The Rainbird Pattern (1972), the novel's tone is more sinister. Screenwriter Ernest Lehman originally wrote the film, under the working title Deception, with a dark tone but was pushed to a lighter, more comical tone by Hitchcock where it took the name Deceit, then finally, Family Plot. + +Knighthood and death + Toward the end of his life, Hitchcock was working on the script for a spy thriller, The Short Night, collaborating with James Costigan, Ernest Lehman and David Freeman. Despite preliminary work, it was never filmed. Hitchcock's health was declining and he was worried about his wife, who had suffered a stroke. The screenplay was eventually published in Freeman's book The Last Days of Alfred Hitchcock (1999). + +Having refused a CBE in 1962, Hitchcock was appointed a Knight Commander of the Most Excellent Order of the British Empire (KBE) in the 1980 New Year Honours. He was too ill to travel to London—he had a pacemaker and was being given cortisone injections for his arthritis—so on 3 January 1980 the British consul general presented him with the papers at Universal Studios. Asked by a reporter after the ceremony why it had taken the Queen so long, Hitchcock quipped, "I suppose it was a matter of carelessness." Cary Grant, Janet Leigh and others attended a luncheon afterwards. + +His last public appearance was on 16 March 1980, when he introduced the next year's winner of the American Film Institute award. He died of kidney failure the following month, on 29 April, in his Bel Air home. Donald Spoto, one of Hitchcock's biographers, wrote that Hitchcock had declined to see a priest, but according to Jesuit priest Mark Henninger, he and another priest, Tom Sullivan, celebrated Mass at the filmmaker's home, and Sullivan heard his confession. Hitchcock was survived by his wife and daughter. His funeral was held at Good Shepherd Catholic Church in Beverly Hills on 30 April, after which his body was cremated. His remains were scattered over the Pacific Ocean on 10 May 1980. + +Filmmaking + +Style and themes + +The "Hitchcockian" style includes the use of editing and camera movement to mimic a person's gaze, thereby turning viewers into voyeurs, and framing shots to maximise anxiety and fear. The film critic Robin Wood wrote that the meaning of a Hitchcock film "is there in the method, in the progression from shot to shot. A Hitchcock film is an organism, with the whole implied in every detail and every detail related to the whole." + +Hitchcock's film production career evolved from small-scale silent films to financially significant sound films. Hitchcock remarked that he was influenced by early filmmakers George Méliès, D.W. Griffith and Alice Guy-Blaché. His silent films between 1925 and 1929 were in the crime and suspense genres, but also included melodramas and comedies. Whilst visual storytelling was pertinent during the silent era, even after the arrival of sound, Hitchcock still relied on visuals in cinema; he referred to this emphasis on visual storytelling as "pure cinema". In Britain, he honed his craft so that by the time he moved to Hollywood, the director had perfected his style and camera techniques. Hitchcock later said that his British work was the "sensation of cinema", whereas the American phase was when his "ideas were fertilised". Scholar Robin Wood writes that the director's first two films, The Pleasure Garden and The Mountain Eagle, were influenced by German Expressionism. Afterward, he discovered Soviet cinema, and Sergei Eisenstein's and Vsevolod Pudovkin's theories of montage. 1926's The Lodger was inspired by both German and Soviet aesthetics, styles which solidified the rest of his career. Although Hitchcock's work in the 1920s found some success, several British reviewers criticised Hitchcock's films for being unoriginal and conceited. Raymond Durgnat opined that Hitchcock's films were carefully and intelligently constructed, but thought they can be shallow and rarely present a "coherent worldview". + +Earning the title "Master of Suspense", the director experimented with ways to generate tension in his work. He said, "My suspense work comes out of creating nightmares for the audience. And I play with an audience. I make them gasp and surprise them and shock them. When you have a nightmare, it's awfully vivid if you're dreaming that you're being led to the electric chair. Then you're as happy as can be when you wake up because you're relieved." During filming of North by Northwest, Hitchcock explained his reasons for recreating the set of Mount Rushmore: "The audience responds in proportion to how realistic you make it. One of the dramatic reasons for this type of photography is to get it looking so natural that the audience gets involved and believes, for the time being, what's going on up there on the screen." In a 1963 interview with Italian journalist Oriana Fallaci, Hitchcock was asked how in spite of appearing to be a pleasant, innocuous man, he seemed to enjoy making films involving suspense and terrifying crime. He responded: + +Hitchcock's films, from the silent to the sound era, contained a number of recurring themes that he is famous for. His films explored audience as a voyeur, notably in Rear Window, Marnie and Psycho. He understood that human beings enjoy voyeuristic activities and made the audience participate in it through the character's actions. Of his fifty-three films, eleven revolved around stories of mistaken identity, where an innocent protagonist is accused of a crime and is pursued by police. In most cases, it is an ordinary, everyday person who finds themselves in a dangerous situation. Hitchcock told Truffaut: "That's because the theme of the innocent man being accused, I feel, provides the audience with a greater sense of danger. It's easier for them to identify with him than with a guilty man on the run." One of his constant themes were the struggle of a personality torn between "order and chaos"; known as the notion of "double", which is a comparison or contrast between two characters or objects: the double representing a dark or evil side. + +According to Robin Wood, Hitchcock retained a feeling of ambivalence towards homosexuality, despite working with gay actors throughout his career. Donald Spoto suggests that Hitchcock's sexually repressive childhood may have contributed to his exploration of deviancy. During the 1950s, the Motion Picture Production Code prohibited direct references to homosexuality but the director was known for his subtle references, and pushing the boundaries of the censors. Moreover, Shadow of a Doubt has a double incest theme through the storyline, expressed implicitly through images. Author Jane Sloan argues that Hitchcock was drawn to both conventional and unconventional sexual expression in his work, and the theme of marriage was usually presented in a "bleak and skeptical" manner. It was also not until after his mother's death in 1942, that Hitchcock portrayed motherly figures as "notorious monster-mothers". The espionage backdrop, and murders committed by characters with psychopathic tendencies were common themes too. In Hitchcock's depiction of villains and murderers, they were usually charming and friendly, forcing viewers to identify with them. The director's strict childhood and Jesuit education may have led to his distrust of authoritarian figures such as policemen and politicians; a theme which he has explored. Also, he used the "MacGuffin"—the use of an object, person or event to keep the plot moving along even if it was non-essential to the story. Some examples include the microfilm in North by Northwest and the stolen $40,000 in Psycho. + +Hitchcock appears briefly in most of his own films. For example, he is seen struggling to get a double bass onto a train (Strangers on a Train), walking dogs out of a pet shop (The Birds), fixing a neighbour's clock (Rear Window), as a shadow (Family Plot), sitting at a table in a photograph (Dial M for Murder), and riding a bus (North by Northwest, To Catch a Thief). + +Representation of women +Hitchcock's portrayal of women has been the subject of much scholarly debate. Bidisha wrote in The Guardian in 2010: "There's the vamp, the tramp, the snitch, the witch, the slink, the double-crosser and, best of all, the demon mommy. Don't worry, they all get punished in the end." In a widely cited essay in 1975, Laura Mulvey introduced the idea of the male gaze; the view of the spectator in Hitchcock's films, she argued, is that of the heterosexual male protagonist. "The female characters in his films reflected the same qualities over and over again", Roger Ebert wrote in 1996: "They were blonde. They were icy and remote. They were imprisoned in costumes that subtly combined fashion with fetishism. They mesmerised the men, who often had physical or psychological handicaps. Sooner or later, every Hitchcock woman was humiliated." + +The victims in The Lodger are all blondes. In The 39 Steps, Madeleine Carroll is put in handcuffs. Ingrid Bergman, whom Hitchcock directed three times (Spellbound, Notorious, and Under Capricorn), is dark blonde. In Rear Window, Lisa (Grace Kelly) risks her life by breaking into Lars Thorwald's apartment. In To Catch a Thief, Francie (also Kelly) offers to help a man she believes is a burglar. In Vertigo and North by Northwest respectively, Kim Novak and Eva Marie Saint play the blonde heroines. In Psycho, Janet Leigh's character steals $40,000 and is murdered by Norman Bates, a reclusive psychopath. Tippi Hedren, a blonde, appears to be the focus of the attacks in The Birds. In Marnie, the title character, again played by Hedren, is a thief. In Topaz, French actresses Dany Robin as Stafford's wife and Claude Jade as Stafford's daughter are blonde heroines, the mistress was played by brunette Karin Dor. Hitchcock's last blonde heroine was Barbara Harris as a phony psychic turned amateur sleuth in Family Plot (1976), his final film. In the same film, the diamond smuggler played by Karen Black wears a long blonde wig in several scenes. + +Hitchcock's films often feature characters struggling in their relationships with their mothers, such as Norman Bates in Psycho. In North by Northwest, Roger Thornhill (Cary Grant) is an innocent man ridiculed by his mother for insisting that shadowy, murderous men are after him. In The Birds, the Rod Taylor character, an innocent man, finds his world under attack by vicious birds, and struggles to free himself from a clinging mother (Jessica Tandy). The killer in Frenzy has a loathing of women but idolises his mother. The villain Bruno in Strangers on a Train hates his father, but has an incredibly close relationship with his mother (played by Marion Lorne). Sebastian (Claude Rains) in Notorious has a clearly conflicting relationship with his mother, who is (rightly) suspicious of his new bride, Alicia Huberman (Ingrid Bergman). + +Relationship with actors + +Hitchcock became known for having remarked that "actors should be treated like cattle". During the filming of Mr. & Mrs. Smith (1941), Carole Lombard brought three cows onto the set wearing the name tags of Lombard, Robert Montgomery, and Gene Raymond, the stars of the film, to surprise him. In an episode of The Dick Cavett Show, originally broadcast on 8 June 1972, Dick Cavett stated as fact that Hitchcock had once called actors cattle. Hitchcock responded by saying that, at one time, he had been accused of calling actors cattle. "I said that I would never say such an unfeeling, rude thing about actors at all. What I probably said, was that all actors should be treated like cattle...In a nice way of course." He then described Carole Lombard's joke, with a smile. + +Hitchcock believed that actors should concentrate on their performances and leave work on script and character to the directors and screenwriters. He told Bryan Forbes in 1967: "I remember discussing with a method actor how he was taught and so forth. He said, 'We're taught using improvisation. We are given an idea and then we are turned loose to develop in any way we want to.' I said, 'That's not acting. That's writing.'" + +Recalling their experiences on Lifeboat for Charles Chandler, author of It's Only a Movie: Alfred Hitchcock A Personal Biography, Walter Slezak said that Hitchcock "knew more about how to help an actor than any director I ever worked with", and Hume Cronyn dismissed the idea that Hitchcock was not concerned with his actors as "utterly fallacious", describing at length the process of rehearsing and filming Lifeboat. + +Critics observed that, despite his reputation as a man who disliked actors, actors who worked with him often gave brilliant performances. He used the same actors in many of his films; Cary Grant and James Stewart both worked with Hitchcock four times, and Ingrid Bergman and Grace Kelly three. James Mason said that Hitchcock regarded actors as "animated props". For Hitchcock, the actors were part of the film's setting. He told François Truffaut: "The chief requisite for an actor is the ability to do nothing well, which is by no means as easy as it sounds. He should be willing to be used and wholly integrated into the picture by the director and the camera. He must allow the camera to determine the proper emphasis and the most effective dramatic highlights." + +Writing, storyboards and production +Hitchcock planned his scripts in detail with his writers. In Writing with Hitchcock (2001), Steven DeRosa noted that Hitchcock supervised them through every draft, asking that they tell the story visually. Hitchcock told Roger Ebert in 1969: + +Hitchcock's films were extensively storyboarded to the finest detail. He was reported to have never even bothered looking through the viewfinder, since he did not need to, although in publicity photos he was shown doing so. He also used this as an excuse to never have to change his films from his initial vision. If a studio asked him to change a film, he would claim that it was already shot in a single way, and that there were no alternative takes to consider. + +This view of Hitchcock as a director who relied more on pre-production than on the actual production itself has been challenged by Bill Krohn, the American correspondent of French film magazine Cahiers du Cinéma, in his book Hitchcock at Work. After investigating script revisions, notes to other production personnel written by or to Hitchcock, and other production material, Krohn observed that Hitchcock's work often deviated from how the screenplay was written or how the film was originally envisioned. He noted that the myth of storyboards in relation to Hitchcock, often regurgitated by generations of commentators on his films, was to a great degree perpetuated by Hitchcock himself or the publicity arm of the studios. For example, the celebrated crop-spraying sequence of North by Northwest was not storyboarded at all. After the scene was filmed, the publicity department asked Hitchcock to make storyboards to promote the film, and Hitchcock in turn hired an artist to match the scenes in detail. + +Even when storyboards were made, scenes that were shot differed from them significantly. Krohn's analysis of the production of Hitchcock classics like Notorious reveals that Hitchcock was flexible enough to change a film's conception during its production. Another example Krohn notes is the American remake of The Man Who Knew Too Much, whose shooting schedule commenced without a finished script and moreover went over schedule, something that, as Krohn notes, was not an uncommon occurrence on many of Hitchcock's films, including Strangers on a Train and Topaz. While Hitchcock did do a great deal of preparation for all his films, he was fully cognisant that the actual film-making process often deviated from the best-laid plans and was flexible to adapt to the changes and needs of production as his films were not free from the normal hassles faced and common routines used during many other film productions. + +Krohn's work also sheds light on Hitchcock's practice of generally shooting in chronological order, which he notes sent many films over budget and over schedule and, more importantly, differed from the standard operating procedure of Hollywood in the Studio System Era. Equally important is Hitchcock's tendency to shoot alternative takes of scenes. This differed from coverage in that the films were not necessarily shot from varying angles so as to give the editor options to shape the film how they chose (often under the producer's aegis). Rather they represented Hitchcock's tendency to give himself options in the editing room, where he would provide advice to his editors after viewing a rough cut of the work. + +According to Krohn, this and a great deal of other information revealed through his research of Hitchcock's personal papers, script revisions and the like refute the notion of Hitchcock as a director who was always in control of his films, whose vision of his films did not change during production, which Krohn notes has remained the central long-standing myth of Alfred Hitchcock. Both his fastidiousness and attention to detail also found their way into each film poster for his films. Hitchcock preferred to work with the best talent of his day—film poster designers such as Bill Gold and Saul Bass—who would produce posters that accurately represented his films. + +Legacy + +Awards and honours + +Hitchcock was inducted into the Hollywood Walk of Fame on 8 February 1960 with two stars: one for television and a second for motion pictures. In 1978, John Russell Taylor described him as "the most universally recognizable person in the world" and "a straightforward middle-class Englishman who just happened to be an artistic genius". In 2002, MovieMaker named him the most influential director of all time, and a 2007 The Daily Telegraph critics' poll ranked him Britain's greatest director. David Gritten, the newspaper's film critic, wrote: "Unquestionably the greatest filmmaker to emerge from these islands, Hitchcock did more than any director to shape modern cinema, which would be utterly different without him. His flair was for narrative, cruelly withholding crucial information (from his characters and from us) and engaging the emotions of the audience like no one else." In 1992, the Sight & Sound Critics' Poll ranked Hitchcock at No. 4 in its list of "Top 10 Directors" of all time. In 2002, Hitchcock was ranked second in the critics' top ten poll and fifth in the directors' top ten poll in the list of "The Greatest Directors of All Time" compiled by Sight & Sound. Hitchcock was voted the "Greatest Director of 20th Century" in a poll conducted by Japanese film magazine kinema Junpo. In 1996, Entertainment Weekly ranked Hitchcock at No. 1 in its "50 Greatest Directors" list. Hitchcock was ranked at No. 2 on Empires "Top 40 Greatest Directors of All-Time" list in 2005. In 2007, Total Film ranked Hitchcock at No. 1 on its "100 Greatest Film Directors Ever" list. + +He won two Golden Globes, eight Laurel Awards, and five lifetime achievement awards, including the first BAFTA Academy Fellowship Award and, in 1979, an AFI Life Achievement Award. He was nominated five times for an Academy Award for Best Director. Rebecca, nominated for eleven Oscars, won the Academy Award for Best Picture of 1940; another Hitchcock film, Foreign Correspondent, was also nominated that year. By 2021, nine of his films had been selected for preservation by the US National Film Registry: Rebecca (1940; inducted 2018), Shadow of a Doubt (1943; inducted 1991), Notorious (1946; inducted 2006), Strangers on a Train (1951; inducted 2021), Rear Window (1954; inducted 1997), Vertigo (1958; inducted 1989), North by Northwest (1959; inducted 1995), Psycho (1960; inducted 1992) and The Birds (1963; inducted 2016). + +In 2012, Hitchcock was selected by artist Sir Peter Blake, author of the Beatles' Sgt. Pepper's Lonely Hearts Club Band album cover, to appear in a new version of the cover, along with other British cultural figures, and he was featured that year in a BBC Radio 4 series, The New Elizabethans, as someone "whose actions during the reign of Elizabeth II have had a significant impact on lives in these islands and given the age its character". In June 2013 nine restored versions of Hitchcock's early silent films, including The Pleasure Garden (1925), were shown at the Brooklyn Academy of Music's Harvey Theatre; known as "The Hitchcock 9", the travelling tribute was organised by the British Film Institute. + +Archives +The Alfred Hitchcock Collection is housed at the Academy Film Archive in Hollywood, California. It includes home movies, 16mm film shot on the set of Blackmail (1929) and Frenzy (1972), and the earliest known colour footage of Hitchcock. The Academy Film Archive has preserved many of his home movies. The Alfred Hitchcock Papers are housed at the Academy's Margaret Herrick Library. The David O.

They are found in tropical South America. Four species are currently recognized. + +Description +Although the name applies to a group of snakes, it is often used to refer only to one species, in particular, the common or green anaconda (Eunectes murinus), which is the largest snake in the world by weight, and the second longest after the reticulated python. + +Etymology +The South American names anacauchoa and anacaona were suggested in an account by Peter Martyr d'Anghiera, but the idea of a South American origin was questioned by Henry Walter Bates who, in his travels in South America, failed to find any similar name in use. The word anaconda is derived from the name of a snake from Ceylon (Sri Lanka) that John Ray described in Latin in his (1693) as . Ray used a catalogue of snakes from the Leyden museum supplied by Dr. Tancred Robinson, but the description of its habit was based on Andreas Cleyer who in 1684 described a gigantic snake that crushed large animals by coiling around their bodies and crushing their bones. Henry Yule in his Hobson-Jobson notes that the word became more popular due to a piece of fiction published in 1768 in the Scots Magazine by a certain R. Edwin. Edwin that described a 'tiger' being crushed to death by an anaconda, when there actually never were any tigers in Sri Lanka. Yule and Frank Wall noted that the snake was in fact a python and suggested a Tamil origin meaning elephant killer. A Sinhalese origin was also suggested by Donald Ferguson who pointed out that the word ( lightning/large and stem/trunk) was used in Sri Lanka for the small whip snake (Ahaetulla pulverulenta) and somehow got misapplied to the python before myths were created. + +The name commonly used for the anaconda in Brazil is sucuri, sucuriju or sucuriuba. + +Species and other uses of the term "anaconda" +The term "anaconda" has been used to refer to: + + Any member of the genus Eunectes, a group of large, aquatic snakes found in South America: + Eunectes murinus, the green anaconda – the largest species, found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and Trinidad and Tobago + Eunectes notaeus, the yellow anaconda – a small species, found in eastern Bolivia, southern Brazil, Paraguay, and northeastern Argentina + Eunectes deschauenseei, the darkly-spotted anaconda – a rare species, found in northeastern Brazil and coastal French Guiana + Eunectes beniensis, the Bolivian anaconda – the most recently defined species, found in the Departments of Beni and Pando in Bolivia + The term was previously applied imprecisely, indicating any large snake that constricts its prey, though this usage is now archaic. + "Anaconda" is also used as a metaphor for an action aimed at constricting and suffocating an opponent – for example, the Anaconda Plan proposed at the beginning of the American Civil War, in which the Union Army was to effectively "suffocate" the Confederacy. Another example is the anaconda choke in the martial art Brazilian jiu-jitsu, which is performed by wrapping your arms under the opponent's neck and through the armpit, and grasping the biceps of the opposing arm, when caught in this move, you will lose consciousness if you do not tap out. + +See also + Jaguar, a competitor or predator + +Notes + +References + +External links + + + +Eunectes +Snake common names +Altaic () is a controversial proposed language family that would include the Turkic, Mongolic and Tungusic language families and possibly also the Japonic and Koreanic languages. The hypothetical language family has long been rejected by most comparative linguists, although it continues to be supported by a small but stable scholarly minority. Speakers of the constituent languages are currently scattered over most of Asia north of 35° N and in some eastern parts of Europe, extending in longitude from the Balkan Peninsula to Japan. The group is named after the Altai mountain range in the center of Asia. + +The Altaic family was first proposed in the 18th century. It was widely accepted until the 1960s and is still listed in many encyclopedias and handbooks, and references to Altaic as a language family continue to percolate to modern sources through these older sources. Since the 1950s, most comparative linguists have rejected the proposal, after supposed cognates were found not to be valid, hypothesized sound shifts were not found, and Turkic and Mongolic languages were found to be converging rather than diverging over the centuries. The relationship between the Altaic languages is now generally accepted to be the result of a sprachbund rather than common ancestry, with the languages showing influence from prolonged contact. + +The continued use of the term "Altaic" to refer to the various iterations of an Altaic theory, the "Altaic sprachbund" and infrequently as a general term for the region has resulted in confusion around the status of the Altaic hypothesis, with the end result being many Altaicists adopting the name "Transeurasian" for modifications of the family proposal to avoid confusion. This confusion is compounded by literature which refers to Altaic as an accepted hypothesis, which historically was the case. + +Altaic has maintained a limited degree of scholarly support, in contrast to some other early macrofamily proposals. Continued research on Altaic is still being undertaken by a core group of academic linguists, but their research has not found wider support. In particular it has support from the Institute of Linguistics of the Russian Academy of Sciences and remains influential as a substratum of Turanism, where a hypothetical common linguistic ancestor has been used in part as a basis for a multiethnic nationalist movement. + +Earliest attestations +The earliest attested expressions in Proto-Turkic are recorded in various Chinese sources. Anna Dybo identifies in Shizi (330 BCE) and the Book of Han (111 CE) several dozen Proto-Turkic exotisms in Chinese Han transcriptions. Lanhai Wei and Hui Li reconstruct the name of the Xiōngnú ruling house as +PT *Alayundluğ /alajuntˈluγ/ 'piebald horse clan.' + +The earliest known texts in a Turkic language are the Orkhon inscriptions, 720–735 AD. They were deciphered in 1893 by the Danish linguist Vilhelm Thomsen in a scholarly race with his rival, the German–Russian linguist Wilhelm Radloff. However, Radloff was the first to publish the inscriptions. + +The first Tungusic language to be attested is Jurchen, the language of the ancestors of the Manchus. A writing system for it was devised in 1119 AD and an inscription using this system is known from 1185 (see List of Jurchen inscriptions). + +The earliest Mongolic language of which we have written evidence is known as Middle Mongol. It is first attested by an inscription dated to 1224 or 1225 AD, the Stele of Yisüngge, and by the Secret History of the Mongols, written in 1228 (see Mongolic languages). The earliest Para-Mongolic text is the Memorial for Yelü Yanning, written in the Khitan large script and dated to 986 AD. However, the Inscription of Hüis Tolgoi, discovered in 1975 and analysed as being in an early form of Mongolic, has been dated to 604–620 AD. The Bugut inscription dates back to 584 AD. + +Japanese is first attested in the form of names contained in a few short inscriptions in Classical Chinese from the 5th century AD, such as found on the Inariyama Sword. The first substantial text in Japanese, however, is the Kojiki, which dates from 712 AD. It is followed by the Nihon shoki, completed in 720, and then by the Man'yōshū, which dates from c. 771–785, but includes material that is from about 400 years earlier. + +The most important text for the study of early Korean is the Hyangga, a collection of 25 poems, of which some go back to the Three Kingdoms period (57 BC–668 AD), but are preserved in an orthography that only goes back to the 9th century AD. Korean is copiously attested from the mid-15th century on in the phonetically precise Hangul system of writing. + +History of the Altaic family concept + +Origins +The earliest known reference to a unified language group of Turkic, Mongolic and Tungusic languages is from the 1692 work of Nicolaes Witsen which may be based on a 1661 work of Abu al-Ghazi Bahadur Genealogy of the Turkmens. + +A proposed grouping of the Turkic, Mongolic, and Tungusic languages was published in 1730 by Philip Johan von Strahlenberg, a Swedish officer who traveled in the eastern Russian Empire while a prisoner of war after the Great Northern War. However, he may not have intended to imply a closer relationship among those languages. Later proposals to include the Korean and Japanese languages into a "Macro-Altaic" family have always been controversial. The original proposal was sometimes called "Micro-Altaic" by retronymy. Most proponents of Altaic continue to support the inclusion of Korean, but fewer do for Japanese. Some proposals also included Ainuic but this is not widely accepted even among Altaicists themselves. A common ancestral Proto-Altaic language for the "Macro" family has been tentatively reconstructed by Sergei Starostin and others. + +Micro-Altaic includes about 66 living languages, to which Macro-Altaic would add Korean, Jeju, Japanese, and the Ryukyuan languages, for a total of about 74 (depending on what is considered a language and what is considered a dialect). These numbers do not include earlier states of languages, such as Middle Mongol, Old Korean, or Old Japanese. + +Uralo-Altaic hypothesis + +In 1844, the Finnish philologist Matthias Castrén proposed a broader grouping which later came to be called the Ural–Altaic family, which included Turkic, Mongolian, and Manchu-Tungus (=Tungusic) as an "Altaic" branch, and also the Finno-Ugric and Samoyedic languages as the "Uralic" branch (though Castrén himself used the terms "Tataric" and "Chudic"). The name "Altaic" referred to the Altai Mountains in East-Central Asia, which are approximately the center of the geographic range of the three main families. The name "Uralic" referred to the Ural Mountains. + +While the Ural-Altaic family hypothesis can still be found in some encyclopedias, atlases, and similar general references, since the 1960s it has been heavily criticized. Even linguists who accept the basic Altaic family, such as Sergei Starostin, completely discard the inclusion of the "Uralic" branch. + +The term continues to be used for the central Eurasian typological, grammatical and lexical convergence zone. Indeed, "Ural-Altaic" may be preferable to "Altaic" in this sense. For example, Juha Janhunen states that "speaking of 'Altaic' instead of 'Ural-Altaic' is a misconception, for there are no areal or typological features that are specific to 'Altaic' without Uralic." + +Korean and Japanese languages +In 1857, the Austrian scholar Anton Boller suggested adding Japanese to the Ural–Altaic family. + +In the 1920s, G.J. Ramstedt and E.D. Polivanov advocated the inclusion of Korean. Decades later, in his 1952 book, Ramstedt rejected the Ural–Altaic hypothesis but again included Korean in Altaic, an inclusion followed by most leading Altaicists (supporters of the theory) to date. His book contained the first comprehensive attempt to identify regular correspondences among the sound systems within the Altaic language families. + +In 1960, Nicholas Poppe published what was in effect a heavily revised version of Ramstedt's volume on phonology that has since set the standard in Altaic studies. Poppe considered the issue of the relationship of Korean to Turkic-Mongolic-Tungusic not settled. In his view, there were three possibilities: (1) Korean did not belong with the other three genealogically, but had been influenced by an Altaic substratum; (2) Korean was related to the other three at the same level they were related to each other; (3) Korean had split off from the other three before they underwent a series of characteristic changes. + +Roy Andrew Miller's 1971 book Japanese and the Other Altaic Languages convinced most Altaicists that Japanese also belonged to Altaic. Since then, the "Macro-Altaic" has been generally assumed to include Turkic, Mongolic, Tungusic, Korean, and Japanese. + +In 1990, Unger advocated a family consisting of Tungusic, Korean, and Japonic languages, but not Turkic or Mongolic. + +However, many linguists dispute the alleged affinities of Korean and Japanese to the other three groups. Some authors instead tried to connect Japanese to the Austronesian languages. + +In 2017, Martine Robbeets proposed that Japanese (and possibly Korean) originated as a hybrid language. She proposed that the ancestral home of the Turkic, Mongolic, and Tungusic languages was somewhere in northwestern Manchuria. A group of those proto-Altaic ("Transeurasian") speakers would have migrated south into the modern Liaoning province, where they would have been mostly assimilated by an agricultural community with an Austronesian-like language. The fusion of the two languages would have resulted in proto-Japanese and proto-Korean. + +In a typological study that does not directly evaluate the validity of the Altaic hypothesis, Yurayong and Szeto (2020) discuss for Koreanic and Japonic the stages of convergence to the Altaic typological model and subsequent divergence from that model, which resulted in the present typological similarity between Koreanic and Japonic. They state that both are "still so different from the Core Altaic languages that we can even speak of an independent Japanese-Korean type of grammar. Given also that there is neither a strong proof of common Proto-Altaic lexical items nor solid regular sound correspondences but, rather, only lexical and structural borrowings between languages of the Altaic typology, our results indirectly speak in favour of a “Paleo-Asiatic” origin of the Japonic and Koreanic languages." + +The Ainu language +In 1962, John C. Street proposed an alternative classification, with Turkic-Mongolic-Tungusic in one grouping and Korean-Japanese-Ainu in another, joined in what he designated as the "North Asiatic" family. The inclusion of Ainu was adopted also by James Patrie in 1982. + +The Turkic-Mongolic-Tungusic and Korean-Japanese-Ainu groupings were also posited in 2000–2002 by Joseph Greenberg. However, he treated them as independent members of a larger family, which he termed Eurasiatic. + +The inclusion of Ainu is not widely accepted by Altaicists. In fact, no convincing genealogical relationship between Ainu and any other language family has been demonstrated, and it is generally regarded as a language isolate. + +Early criticism and rejection +Starting in the late 1950s, some linguists became increasingly critical of even the minimal Altaic family hypothesis, disputing the alleged evidence of genetic connection between Turkic, Mongolic and Tungusic languages. + +Among the earlier critics were Gerard Clauson (1956), Gerhard Doerfer (1963), and Alexander Shcherbak. They claimed that the words and features shared by Turkic, Mongolic, and Tungusic languages were for the most part borrowings and that the rest could be attributed to chance resemblances. In 1988, Doerfer again rejected all the genetic claims over these major groups. + +Modern controversy +A major continuing supporter of the Altaic hypothesis has been Sergei Starostin, who published a comparative lexical analysis of the Altaic languages in 1991. He concluded that the analysis supported the Altaic grouping, although it was "older than most other language families in Eurasia, such as Indo-European or Finno-Ugric, and this is the reason why the modern Altaic languages preserve few common elements". + +In 1991 and again in 1996, Roy Miller defended the Altaic hypothesis and claimed that the criticisms of Clauson and Doerfer apply exclusively to the lexical correspondences, whereas the most pressing evidence for the theory is the similarities in verbal morphology. + +In 2003, Claus Schönig published a critical overview of the history of the Altaic hypothesis up to that time, siding with the earlier criticisms of Clauson, Doerfer, and Shcherbak. + +In 2003, Starostin, Anna Dybo and Oleg Mudrak published the Etymological Dictionary of the Altaic Languages, which expanded the 1991 lexical lists and added other phonological and grammatical arguments. + +Starostin's book was criticized by Stefan Georg in 2004 and 2005, and by Alexander Vovin in 2005. + +Other defenses of the theory, in response to the criticisms of Georg and Vovin, were published by Starostin in 2005, Blažek in 2006, Robbeets in 2007, and Dybo and G. Starostin in 2008. + +In 2010, Lars Johanson echoed Miller's 1996 rebuttal to the critics, and called for a muting of the polemic. + +List of supporters and critics of the Altaic hypothesis +The list below comprises linguists who have worked specifically on the Altaic problem since the publication of the first volume of Ramstedt's Einführung in 1952.

Agnostic, proponent of a "Transeurasian" verbal morphology not necessarily genealogically linked. + +"Transeurasian" renaming +In Robbeets and Johanson (2010), there was a proposal to replace the name "Altaic" with the name "Transeurasian". While "Altaic" has sometimes included Japonic, Koreanic, and other languages or families, but only on the consideration of particular authors, "Transeurasian" was specifically intended to always include Turkic, Mongolic, Tungusic, Japonic, and Koreanic. Robbeets and Johanson gave as their reasoning for the new term: 1) to avoid confusion between the different uses of Altaic as to which group of languages is included, 2) to reduce the counterproductive polarization between "Pro-Altaists" and "Anti-Altaists"; 3) to broaden the applicability of the term because the suffix -ic implies affinity while -an leaves room for an areal hypothesis; and 4) to eliminate the reference to the Altai mountains as a potential homeland. + +In Robbeets and Savelyev, ed. (2020) there was a concerted effort to distinguish "Altaic" as a subgroup of "Transeurasian" consisting only of Turkic, Mongolic, and Tungusic, while retaining "Transeurasian" as "Altaic" plus Japonic and Koreanic. + +Arguments + +For the Altaic grouping + +Phonological and grammatical features +The original arguments for grouping the "micro-Altaic" languages within a Uralo-Altaic family were based on such shared features as vowel harmony and agglutination. + +According to Roy Miller, the most pressing evidence for the theory is the similarities in verbal morphology. + +The Etymological Dictionary by Starostin and others (2003) proposes a set of sound change laws that would explain the evolution from Proto-Altaic to the descendant languages. For example, although most of today's Altaic languages have vowel harmony, Proto-Altaic as reconstructed by them lacked it; instead, various vowel assimilations between the first and second syllables of words occurred in Turkic, Mongolic, Tungusic, Korean, and Japonic. They also included a number of grammatical correspondences between the languages. + +Shared lexicon +Starostin claimed in 1991 that the members of the proposed Altaic group shared about 15–20% of apparent cognates within a 110-word Swadesh-Yakhontov list; in particular, Turkic–Mongolic 20%, Turkic–Tungusic 18%, Turkic–Korean 17%, Mongolic–Tungusic 22%, Mongolic–Korean 16%, and Tungusic–Korean 21%. The 2003 Etymological Dictionary includes a list of 2,800 proposed cognate sets, as well as a few important changes to the reconstruction of Proto-Altaic. The authors tried hard to distinguish loans between Turkic and Mongolic and between Mongolic and Tungusic from cognates; and suggest words that occur in Turkic and Tungusic but not in Mongolic. All other combinations between the five branches also occur in the book. It lists 144 items of shared basic vocabulary, including words for such items as 'eye', 'ear', 'neck', 'bone', 'blood', 'water', 'stone', 'sun', and 'two'. + +Robbeets and Bouckaert (2018) use Bayesian phylolinguistic methods to argue for the coherence of the "narrow" Altaic languages (Turkic, Mongolic, and Tungusic) together with Japonic and Koreanic, which they refer to as the Transeurasian languages. Their results include the following phylogenetic tree: + +Martine Robbeets (2020) argues that early Transeurasian speakers were originally agriculturalists in northeastern China, only becoming pastoralists later on. + +Against the grouping + +Weakness of lexical and typological data +According to G. Clauson (1956), G. Doerfer (1963), and A. Shcherbak (1963), many of the typological features of the supposed Altaic languages, particularly agglutinative strongly suffixing morphology and subject–object–verb (SOV) word order, often occur together in languages. + +Those critics also argued that the words and features shared by Turkic, Mongolic, and Tungusic languages were for the most part borrowings and that the rest could be attributed to chance resemblances. They noted that there was little vocabulary shared by Turkic and Tungusic languages, though more shared with Mongolic languages. They reasoned that, if all three families had a common ancestor, we should expect losses to happen at random, and not only at the geographical margins of the family; and that the observed pattern is consistent with borrowing. + +According to C. Schönig (2003), after accounting for areal effects, the shared lexicon that could have a common genetic origin was reduced to a small number of monosyllabic lexical roots, including the personal pronouns and a few other deictic and auxiliary items, whose sharing could be explained in other ways; not the kind of sharing expected in cases of genetic relationship. + +The Sprachbund hypothesis + +Instead of a common genetic origin, Clauson, Doerfer, and Shcherbak proposed (in 1956–1966) that Turkic, Mongolic, and Tungusic languages form a Sprachbund: a set of languages with similarities due to convergence through intensive borrowing and long contact, rather than common origin. + +Asya Pereltsvaig further observed in 2011 that, in general, genetically related languages and families tend to diverge over time: the earlier forms are more similar than modern forms. However, she claims that an analysis of the earliest written records of Mongolic and Turkic languages shows the opposite, suggesting that they do not share a common traceable ancestor, but rather have become more similar through language contact and areal effects. + +Hypothesis about the original homeland + +The prehistory of the peoples speaking the "Altaic" languages is largely unknown. Whereas for certain other language families, such as the speakers of Indo-European, Uralic, and Austronesian, it is possible to frame substantial hypotheses, in the case of the proposed Altaic family much remains to be done. + +Some scholars have hypothesised a possible Uralic and Altaic homeland in the Central Asian steppes. + +Chaubey and van Driem propose that the dispersal of ancient Altaic language communities is reflected by the early Holocene dissemination of haplogroup C2 (M217): "If the paternal lineage C2 (M217) is correlated with Altaic linguistic affinity, as appears to be the case for Turkic, Mongolic and Tungusic, then Japanese is no Father Tongue, and neither is Korean. This Y-chromosomal haplogroup accounts for 11% of Korean paternal lineages, and the frequency of the lineage is even more reduced in Japan. Yet this molecular marker may still be a tracer for the introduction of Altaic language to the archipelago, where the paternal lineage has persisted, albeit in a frequency of just 6%." + +According to Juha Janhunen, the ancestral languages of Turkic, Mongolic, Tungusic, Korean, and Japanese were spoken in a relatively small area comprising present-day North Korea, Southern Manchuria, and Southeastern Mongolia. However Janhunen is sceptical about an affiliation of Japanese to Altaic, while András Róna-Tas remarked that a relationship between Altaic and Japanese, if it ever existed, must be more remote than the relationship of any two of the Indo-European languages. Ramsey stated that "the genetic relationship between Korean and Japanese, if it in fact exists, is probably more complex and distant than we can imagine on the basis of our present state of knowledge". + +Supporters of the Altaic hypothesis formerly set the date of the Proto-Altaic language at around 4000 BC, but today at around 5000 BC or 6000 BC. This would make Altaic a language family older than Indo-European (around 3000 to 4000 BC according to mainstream hypotheses) but considerably younger than Afroasiatic (c. 10,000 BC or 11,000 to 16,000 BC according to different sources). + +See also + Classification of the Japonic languages + Nostratic languages + Pan-Turanism + Turco-Mongol + Uralo-Siberian languages + Xiongnu + Comparison of Japanese and Korean + +References + +Notes + +Citations + +Sources + +Aalto, Pentti. 1955.

It has the highest sociolinguistic prestige locally, as it is the variation used in the media and for other formal situations. In less formal situations, Austrians use Bavarian and Alemannic dialects, which are traditionally spoken but rarely written in Austria. It has been formalized and standardized (in Austria) since publishing the Österreichisches Wörterbuch by the Austrian Ministry of Education, Science and Research in 1951. + +History +Austrian German has its beginning in the mid-18th century, when Empress Maria Theresa and her son Joseph II introduced compulsory schooling in 1774, and several reforms of administration in their multilingual Habsburg Empire. At the time, the written standard was Oberdeutsche Schreibsprache (Upper German written language), which was highly influenced by the Bavarian and Alemannic dialects of Austria. Another option was to create a new standard based on the Southern German dialects, as proposed by the linguist Johann Siegmund Popowitsch. Instead they decided for pragmatic reasons to adopt the already-standardized chancellery language of Saxony (Sächsische Kanzleisprache or Meißner Kanzleideutsch), which was based on the administrative language of the non-Austrian area of Meißen and Dresden. +Austria High German (Hochdeutsch in Österreich, not to be confused with the Bavarian Austria German dialects) has the same geographic origin as the Swiss High German (Schweizer Hochdeutsch, not to be confused with the Alemannic Swiss German dialects). + +The process of introducing the new written standard was led by Joseph von Sonnenfels. + +Since 1951, the standardized form of Austrian German for official texts and schools has been defined by the ("Austrian Dictionary"), published under the authority of the Austrian Federal Ministry of Education, Arts and Culture. + +Standard Austrian German +The official Austrian dictionary, , prescribes grammatical and spelling rules that define the official language. + +Austrian delegates participated in the international working group that drafted the German spelling reform of 1996 and several conferences leading up to the reform were hosted in Vienna at the invitation of the Austrian federal government. Austria adopted it as a signatory, along with Germany, Switzerland, and Liechtenstein, of an international memorandum of understanding () signed in Vienna in 1996. + +The eszett or "sharp s" (ß) is used in Austria, as in Germany but unlike in Switzerland. + +Because of German's pluricentric nature, German dialects in Austria should not be confused with the variety of Standard Austrian German spoken by most Austrians, which is distinct from that of Germany or Switzerland. + +Distinctions in vocabulary persist, for example, in culinary terms, for which communication with Germans is frequently difficult, and administrative and legal language because of Austria's exclusion from the development of a German nation-state in the late 19th century and its manifold particular traditions. A comprehensive collection of Austrian-German legal, administrative and economic terms is offered in Markhardt, Heidemarie: Wörterbuch der österreichischen Rechts-, Wirtschafts- und Verwaltungsterminologie (Peter Lang, 2006). + +Former spoken standard +Until 1918, the spoken standard in Austria was the , a sociolect spoken by the imperial Habsburg family and the nobility of Austria-Hungary. The sociolect, a variety of Standard German, is influenced by Viennese German and other Austro-Bavarian dialects spoken in eastern Austria but is slightly nasalized. + +Special written forms +For many years, Austria had a special form of the language for official government documents that is known as , or "Austrian chancellery language". It is a very traditional form of the language, probably derived from medieval deeds and documents, and has a very complex structure and vocabulary generally reserved for such documents. For most speakers (even native speakers), this form of the language is generally difficult to understand, as it contains many highly-specialised terms for diplomatic, internal, official, and military matters. There are no regional variations because the special written form has been used mainly by a government that has now for centuries been based in Vienna. + + is now used less and less because of various administrative reforms that reduced the number of traditional civil servants (). As a result, Standard Austrian German is replacing it in government and administrative texts. + +European Union +When Austria became a member of the European Union, 23 food-related terms were listed in its accession agreement as having the same legal status as the equivalent terms used in Germany, +for example, the words for "potato", "tomato", and "Brussels sprouts". (Examples in "Vocabulary") +Austrian German is the only variety of a pluricentric language recognized under international law or EU primary law. + +Grammar + +Verbs +In Austria, as in the German-speaking parts of Switzerland and in southern Germany, verbs that express a state tend to use as the auxiliary verb in the perfect, as well as verbs of movement. Verbs which fall into this category include sitzen (to sit), liegen (to lie) and, in parts of Styria and Carinthia, schlafen (to sleep). Therefore, the perfect of these verbs would be ich bin gesessen, ich bin gelegen and ich bin geschlafen, respectively. + +In Germany, the words stehen (to stand) and gestehen (to confess) are identical in the present perfect: habe gestanden. The Austrian variant avoids that potential ambiguity (bin gestanden from stehen, "to stand"; and habe gestanden from gestehen, "to confess": "der Verbrecher ist vor dem Richter gestanden und hat gestanden"). + +In addition, the preterite (simple past) is very rarely used in Austria, especially in the spoken language, with the exception of some modal verbs (ich sollte, ich wollte). + +Vocabulary +There are many official terms that differ in Austrian German from their usage in most parts of Germany. Words used in Austria are Jänner (January) rather than Januar, Feber (seldom, February) along with Februar, heuer (this year) along with dieses Jahr, Stiege (stairs) along with Treppen, Rauchfang (chimney) instead of Schornstein, many administrative, legal and political terms, and many food terms, including the following: + +There are, however, some false friends between the two regional varieties: +Kasten (wardrobe) along with or instead of Schrank (and, similarly, Eiskasten along with Kühlschrank, fridge), as opposed to Kiste (box) instead of Kasten. Kiste in Germany means both "box" and "chest". +Sessel (chair) instead of Stuhl. Sessel means "" in Germany and Stuhl means "stool (faeces)" in both varieties. + +Dialects + +Classification +Dialects of the Austro-Bavarian group, which also comprises dialects from Bavaria +Central Austro-Bavarian (along the main rivers Isar and Danube, spoken in the northern parts of the State of Salzburg, Upper Austria, Lower Austria, and northern Burgenland) +Viennese German +Southern Austro-Bavarian (in Tyrol, South Tyrol, Carinthia, Styria, and the southern parts of Salzburg and Burgenland) +Vorarlbergerisch, spoken in Vorarlberg, is a High Alemannic dialect. + +Regional accents +In addition to the standard variety, in everyday life most Austrians speak one of a number of Upper German dialects. + +While strong forms of the various dialects are not fully mutually intelligible to northern Germans, communication is much easier in Bavaria, especially rural areas, where the Bavarian dialect still predominates as the mother tongue. The Central Austro-Bavarian dialects are more intelligible to speakers of Standard German than the Southern Austro-Bavarian dialects of Tyrol. + +Viennese, the Austro-Bavarian dialect of Vienna, is seen for many in Germany as quintessentially Austrian. The people of Graz, the capital of Styria, speak yet another dialect which is not very Styrian and more easily understood by people from other parts of Austria than other Styrian dialects, for example from western Styria. + +Simple words in the various dialects are very similar, but pronunciation is distinct for each and, after listening to a few spoken words, it may be possible for an Austrian to realise which dialect is being spoken. However, in regard to the dialects of the deeper valleys of the Tyrol, other Tyroleans are often unable to understand them. Speakers from the different provinces of Austria can easily be distinguished from each other by their particular accents (probably more so than Bavarians), those of Carinthia, Styria, Vienna, Upper Austria, and the Tyrol being very characteristic. Speakers from those regions, even those speaking Standard German, can usually be easily identified by their accent, even by an untrained listener. + +Several of the dialects have been influenced by contact with non-Germanic linguistic groups, such as the dialect of Carinthia, where, in the past, many speakers were bilingual (and, in the southeastern portions of the state, many still are even today) with Slovene, and the dialect of Vienna, which has been influenced by immigration during the Austro-Hungarian period, particularly from what is today the Czech Republic. The German dialects of South Tyrol have been influenced by local Romance languages, particularly noticeable with the many loanwords from Italian and Ladin. + +The geographic borderlines between the different accents (isoglosses) coincide strongly with the borders of the states and also with the border with Bavaria, with Bavarians having a markedly different rhythm of speech in spite of the linguistic similarities. + +References + +Notes + +Citations + +Works cited + +Further reading + Ammon, Ulrich: Die deutsche Sprache in Deutschland, Österreich und der Schweiz: Das Problem der nationalen Varietäten. de Gruyter, Berlin/New York 1995. + Ammon, Ulrich / Hans Bickel, Jakob Ebner u. a.: Variantenwörterbuch des Deutschen.

Informally put, the axiom of choice says that given any collection of sets, each containing at least one element, it is possible to construct a new set by arbitrarily choosing one element from each set, even if the collection is infinite. Formally, it states that for every indexed family of nonempty sets, there exists an indexed set such that for every . The axiom of choice was formulated in 1904 by Ernst Zermelo in order to formalize his proof of the well-ordering theorem. + +In many cases, a set arising from choosing elements arbitrarily can be made without invoking the axiom of choice; this is, in particular, the case if the number of sets from which to choose the elements is finite, or if a canonical rule on how to choose the elements is available – some distinguishing property that happens to hold for exactly one element in each set. An illustrative example is sets picked from the natural numbers. From such sets, one may always select the smallest number, e.g. given the sets {{4, 5, 6}, {10, 12}, {1, 400, 617, 8000}}, the set containing each smallest element is {4, 10, 1}. In this case, "select the smallest number" is a choice function. Even if infinitely many sets were collected from the natural numbers, it will always be possible to choose the smallest element from each set to produce a set. That is, the choice function provides the set of chosen elements. However, no definite choice function is known for the collection of all non-empty subsets of the real numbers. In that case, the axiom of choice must be invoked. + +Bertrand Russell coined an analogy: for any (even infinite) collection of pairs of shoes, one can pick out the left shoe from each pair to obtain an appropriate collection (i.e. set) of shoes; this makes it possible to define a choice function directly. For an infinite collection of pairs of socks (assumed to have no distinguishing features), there is no obvious way to make a function that forms a set out of selecting one sock from each pair, without invoking the axiom of choice. + +Although originally controversial, the axiom of choice is now used without reservation by most mathematicians, and it is included in the standard form of axiomatic set theory, Zermelo–Fraenkel set theory with the axiom of choice (ZFC). One motivation for this use is that a number of generally accepted mathematical results, such as Tychonoff's theorem, require the axiom of choice for their proofs. Contemporary set theorists also study axioms that are not compatible with the axiom of choice, such as the axiom of determinacy. The axiom of choice is avoided in some varieties of constructive mathematics, although there are varieties of constructive mathematics in which the axiom of choice is embraced. + +Statement +A choice function (also called selector or selection) is a function f, defined on a collection X of nonempty sets, such that for every set A in X, f(A) is an element of A. With this concept, the axiom can be stated: + +Formally, this may be expressed as follows: + +Thus, the negation of the axiom of choice states that there exists a collection of nonempty sets that has no choice function. (, so where is negation.) + +Each choice function on a collection X of nonempty sets is an element of the Cartesian product of the sets in X. This is not the most general situation of a Cartesian product of a family of sets, where a given set can occur more than once as a factor; however, one can focus on elements of such a product that select the same element every time a given set appears as factor, and such elements correspond to an element of the Cartesian product of all distinct sets in the family. The axiom of choice asserts the existence of such elements; it is therefore equivalent to: + +Given any family of nonempty sets, their Cartesian product is a nonempty set. + +Nomenclature ZF, AC, and ZFC +In this article and other discussions of the Axiom of Choice the following abbreviations are common: +AC – the Axiom of Choice. More rarely, AoC is used. +ZF – Zermelo–Fraenkel set theory omitting the Axiom of Choice. +ZFC – Zermelo–Fraenkel set theory, extended to include the Axiom of Choice. + +Variants +There are many other equivalent statements of the axiom of choice. These are equivalent in the sense that, in the presence of other basic axioms of set theory, they imply the axiom of choice and are implied by it. + +One variation avoids the use of choice functions by, in effect, replacing each choice function with its range: +Given any set X of pairwise disjoint non-empty sets, there exists at least one set C that contains exactly one element in common with each of the sets in X. +This guarantees for any partition of a set X the existence of a subset C of X containing exactly one element from each part of the partition. + +Another equivalent axiom only considers collections X that are essentially powersets of other sets: +For any set A, the power set of A (with the empty set removed) has a choice function. +Authors who use this formulation often speak of the choice function on A, but this is a slightly different notion of choice function. Its domain is the power set of A (with the empty set removed), and so makes sense for any set A, whereas with the definition used elsewhere in this article, the domain of a choice function on a collection of sets is that collection, and so only makes sense for sets of sets. With this alternate notion of choice function, the axiom of choice can be compactly stated as +Every set has a choice function. +which is equivalent to +For any set A there is a function f such that for any non-empty subset B of A, f(B) lies in B. +The negation of the axiom can thus be expressed as: +There is a set A such that for all functions f (on the set of non-empty subsets of A), there is a B such that f(B) does not lie in B. + +Restriction to finite sets +The usual statement of the axiom of choice does not specify whether the collection of nonempty sets is finite or infinite, and thus implies that every finite collection of nonempty sets has a choice function. However, that particular case is a theorem of the Zermelo–Fraenkel set theory without the axiom of choice (ZF); it is easily proved by the principle of finite induction. In the even simpler case of a collection of one set, a choice function just corresponds to an element, so this instance of the axiom of choice says that every nonempty set has an element; this holds trivially. The axiom of choice can be seen as asserting the generalization of this property, already evident for finite collections, to arbitrary collections. + +Usage +Until the late 19th century, the axiom of choice was often used implicitly, although it had not yet been formally stated. For example, after having established that the set X contains only non-empty sets, a mathematician might have said "let F(s) be one of the members of s for all s in X" to define a function F. In general, it is impossible to prove that F exists without the axiom of choice, but this seems to have gone unnoticed until Zermelo. + +Examples +The nature of the individual nonempty sets in the collection may make it possible to avoid the axiom of choice even for certain infinite collections. For example, suppose that each member of the collection X is a nonempty subset of the natural numbers. Every such subset has a smallest element, so to specify our choice function we can simply say that it maps each set to the least element of that set. This gives us a definite choice of an element from each set, and makes it unnecessary to add the axiom of choice to our axioms of set theory. + +The difficulty appears when there is no natural choice of elements from each set. If we cannot make explicit choices, how do we know that our selection forms a legitimate set (as defined by the other ZF axioms of set theory)? For example, suppose that X is the set of all non-empty subsets of the real numbers. First we might try to proceed as if X were finite. If we try to choose an element from each set, then, because X is infinite, our choice procedure will never come to an end, and consequently, we shall never be able to produce a choice function for all of X. Next we might try specifying the least element from each set. But some subsets of the real numbers do not have least elements. For example, the open interval (0,1) does not have a least element: if x is in (0,1), then so is x/2, and x/2 is always strictly smaller than x. So this attempt also fails. + +Additionally, consider for instance the unit circle S, and the action on S by a group G consisting of all rational rotations. Namely, these are rotations by angles which are rational multiples of π. Here G is countable while S is uncountable. Hence S breaks up into uncountably many orbits under G. Using the axiom of choice, we could pick a single point from each orbit, obtaining an uncountable subset X of S with the property that all of its translates by G are disjoint from X. The set of those translates partitions the circle into a countable collection of disjoint sets, which are all pairwise congruent. Since X is not measurable for any rotation-invariant countably additive finite measure on S, finding an algorithm to form a set from selecting a point in each orbit requires that one add the axiom of choice to our axioms of set theory. See non-measurable set for more details. + +The reason that we are able to choose least elements from subsets of the natural numbers is the fact that the natural numbers are well-ordered: every nonempty subset of the natural numbers has a unique least element under the natural ordering. One might say, "Even though the usual ordering of the real numbers does not work, it may be possible to find a different ordering of the real numbers which is a well-ordering. Then our choice function can choose the least element of every set under our unusual ordering." The problem then becomes that of constructing a well-ordering, which turns out to require the axiom of choice for its existence; every set can be well-ordered if and only if the axiom of choice holds. + +Criticism and acceptance +A proof requiring the axiom of choice may establish the existence of an object without explicitly defining the object in the language of set theory. For example, while the axiom of choice implies that there is a well-ordering of the real numbers, there are models of set theory with the axiom of choice in which no well-ordering of the reals is definable. Similarly, although a subset of the real numbers that is not Lebesgue measurable can be proved to exist using the axiom of choice, it is consistent that no such set is definable. + +The axiom of choice proves the existence of these intangibles (objects that are proved to exist, but which cannot be explicitly constructed), which may conflict with some philosophical principles. Because there is no canonical well-ordering of all sets, a construction that relies on a well-ordering may not produce a canonical result, even if a canonical result is desired (as is often the case in category theory). This has been used as an argument against the use of the axiom of choice. + +Another argument against the axiom of choice is that it implies the existence of objects that may seem counterintuitive. One example is the Banach–Tarski paradox which says that it is possible to decompose the 3-dimensional solid unit ball into finitely many pieces and, using only rotations and translations, reassemble the pieces into two solid balls each with the same volume as the original. The pieces in this decomposition, constructed using the axiom of choice, are non-measurable sets. + +Despite these seemingly paradoxical facts, most mathematicians accept the axiom of choice as a valid principle for proving new results in mathematics. The debate is interesting enough, however, that it is considered of note when a theorem in ZFC (ZF plus AC) is logically equivalent (with just the ZF axioms) to the axiom of choice, and mathematicians look for results that require the axiom of choice to be false, though this type of deduction is less common than the type which requires the axiom of choice to be true. + +It is possible to prove many theorems using neither the axiom of choice nor its negation; such statements will be true in any model of ZF, regardless of the truth or falsity of the axiom of choice in that particular model. The restriction to ZF renders any claim that relies on either the axiom of choice or its negation unprovable. For example, the Banach–Tarski paradox is neither provable nor disprovable from ZF alone: it is impossible to construct the required decomposition of the unit ball in ZF, but also impossible to prove there is no such decomposition. Similarly, all the statements listed below which require choice or some weaker version thereof for their proof are unprovable in ZF, but since each is provable in ZF plus the axiom of choice, there are models of ZF in which each statement is true. Statements such as the Banach–Tarski paradox can be rephrased as conditional statements, for example, "If AC holds, then the decomposition in the Banach–Tarski paradox exists." Such conditional statements are provable in ZF when the original statements are provable from ZF and the axiom of choice. + +In constructive mathematics + +As discussed above, in ZFC, the axiom of choice is able to provide "nonconstructive proofs" in which the existence of an object is proved although no explicit example is constructed. ZFC, however, is still formalized in classical logic. The axiom of choice has also been thoroughly studied in the context of constructive mathematics, where non-classical logic is employed. The status of the axiom of choice varies between different varieties of constructive mathematics. + +In Martin-Löf type theory and higher-order Heyting arithmetic, the appropriate statement of the axiom of choice is (depending on approach) included as an axiom or provable as a theorem. Errett Bishop argued that the axiom of choice was constructively acceptable, saying + +In constructive set theory, however, Diaconescu's theorem shows that the axiom of choice implies the law of excluded middle (unlike in Martin-Löf type theory, where it does not). Thus the axiom of choice is not generally available in constructive set theory. A cause for this difference is that the axiom of choice in type theory does not have the extensionality properties that the axiom of choice in constructive set theory does. + +Some results in constructive set theory use the axiom of countable choice or the axiom of dependent choice, which do not imply the law of the excluded middle in constructive set theory. Although the axiom of countable choice in particular is commonly used in constructive mathematics, its use has also been questioned. + +Independence + +In 1938, Kurt Gödel showed that the negation of the axiom of choice is not a theorem of ZF by constructing an inner model (the constructible universe) which satisfies ZFC and thus showing that ZFC is consistent if ZF itself is consistent. In 1963, Paul Cohen employed the technique of forcing, developed for this purpose, to show that, assuming ZF is consistent, the axiom of choice itself is not a theorem of ZF. He did this by constructing a much more complex model which satisfies ZF¬C (ZF with the negation of AC added as axiom) and thus showing that ZF¬C is consistent. + +Together these results establish that the axiom of choice is logically independent of ZF. The assumption that ZF is consistent is harmless because adding another axiom to an already inconsistent system cannot make the situation worse. Because of independence, the decision whether to use the axiom of choice (or its negation) in a proof cannot be made by appeal to other axioms of set theory. The decision must be made on other grounds. + +One argument given in favor of using the axiom of choice is that it is convenient to use it because it allows one to prove some simplifying propositions that otherwise could not be proved. Many theorems which are provable using choice are of an elegant general character: the cardinalities of any two sets are comparable, every nontrivial ring with unity has a maximal ideal, every vector space has a basis, every connected graph has a spanning tree, and every product of compact spaces is compact, among many others. Without the axiom of choice, these theorems may not hold for mathematical objects of large cardinality. + +The proof of the independence result also shows that a wide class of mathematical statements, including all statements that can be phrased in the language of Peano arithmetic, are provable in ZF if and only if they are provable in ZFC. Statements in this class include the statement that P = NP, the Riemann hypothesis, and many other unsolved mathematical problems. When one attempts to solve problems in this class, it makes no difference whether ZF or ZFC is employed if the only question is the existence of a proof. It is possible, however, that there is a shorter proof of a theorem from ZFC than from ZF. + +The axiom of choice is not the only significant statement which is independent of ZF. For example, the generalized continuum hypothesis (GCH) is not only independent of ZF, but also independent of ZFC. However, ZF plus GCH implies AC, making GCH a strictly stronger claim than AC, even though they are both independent of ZF. + +Stronger axioms +The axiom of constructibility and the generalized continuum hypothesis each imply the axiom of choice and so are strictly stronger than it. In class theories such as Von Neumann–Bernays–Gödel set theory and Morse–Kelley set theory, there is an axiom called the axiom of global choice that is stronger than the axiom of choice for sets because it also applies to proper classes. The axiom of global choice follows from the axiom of limitation of size. Tarski's axiom, which is used in Tarski–Grothendieck set theory and states (in the vernacular) that every set belongs to Grothendieck universe, is stronger than the axiom of choice. + +Equivalents +There are important statements that, assuming the axioms of ZF but neither AC nor ¬AC, are equivalent to the axiom of choice. The most important among them are Zorn's lemma and the well-ordering theorem. In fact, Zermelo initially introduced the axiom of choice in order to formalize his proof of the well-ordering theorem. + +Set theory +Tarski's theorem about choice: For every infinite set A, there is a bijective map between the sets A and A×A. +Trichotomy: If two sets are given, then either they have the same cardinality, or one has a smaller cardinality than the other. +Given two non-empty sets, one has a surjection to the other. +Every surjective function has a right inverse. +The Cartesian product of any family of nonempty sets is nonempty. In other words, every family of nonempty sets has a choice function (i.e. a function which maps each of the nonempty sets to one of its elements). +König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals. (The reason for the term "colloquially" is that the sum or product of a "sequence" of cardinals cannot itself be defined without some aspect of the axiom of choice.) +Well-ordering theorem: Every set can be well-ordered. Consequently, every cardinal has an initial ordinal. +Every element of a partially ordered set S is the minimal element of a well-ordered subset having no strict upper bound in S. +Zorn's lemma: Every non-empty partially ordered set in which every chain (i.e., totally ordered subset) has an upper bound contains at least one maximal element. +Hausdorff maximal principle: Every partially ordered set has a maximal chain. Equivalently, in any partially ordered set, every chain can be extended to a maximal chain. +Tukey's lemma: Every non-empty collection of finite character has a maximal element with respect to inclusion. +Antichain principle: Every partially ordered set has a maximal antichain. Equivalently, in any partially ordered set, every antichain can be extended to a maximal antichain. +Abstract algebra +Every vector space has a basis (i.e., a linearly independent spanning subset). In other words, vector spaces are equivalent to free modules. +Krull's theorem: Every unital ring (other than the trivial ring) contains a maximal ideal. Equivalently, in any nontrivial unital ring, every ideal can be extended to a maximal ideal. +For every non-empty set S there is a binary operation defined on S that gives it a group structure. (A cancellative binary operation is enough, see group structure and the axiom of choice.) +Every free abelian group is projective. +Baer's criterion: Every divisible abelian group is injective. +Every set is a projective object in the category Set of sets. +Functional analysis +The closed unit ball of the dual of a normed vector space over the reals has an extreme point. +Point-set topology +The Cartesian product of any family of connected topological spaces is connected. +Tychonoff's theorem: The Cartesian product of any family of compact topological spaces is compact. +In the product topology, the closure of a product of subsets is equal to the product of the closures. +Mathematical logic +If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem; see the section "Weaker forms" below. +Algebraic topology +Every connected graph has a spanning tree. Equivalently, every nonempty graph has a spanning forest. + +Category theory +There are several results in category theory which invoke the axiom of choice for their proof. These results might be weaker than, equivalent to, or stronger than the axiom of choice, depending on the strength of the technical foundations. For example, if one defines categories in terms of sets, that is, as sets of objects and morphisms (usually called a small category), or even locally small categories, whose hom-objects are sets, then there is no category of all sets, and so it is difficult for a category-theoretic formulation to apply to all sets. On the other hand, other foundational descriptions of category theory are considerably stronger, and an identical category-theoretic statement of choice may be stronger than the standard formulation, à la class theory, mentioned above. + +Examples of category-theoretic statements which require choice include: +Every small category has a skeleton. +If two small categories are weakly equivalent, then they are equivalent. +Every continuous functor on a small-complete category which satisfies the appropriate solution set condition has a left-adjoint (the Freyd adjoint functor theorem). + +Weaker forms +There are several weaker statements that are not equivalent to the axiom of choice, but are closely related. One example is the axiom of dependent choice (DC). A still weaker example is the axiom of countable choice (ACω or CC), which states that a choice function exists for any countable set of nonempty sets. These axioms are sufficient for many proofs in elementary mathematical analysis, and are consistent with some principles, such as the Lebesgue measurability of all sets of reals, that are disprovable from the full axiom of choice. + +Given an ordinal parameter α ≥ ω+2 — for every set S with rank less than α, S is well-orderable. +Given an ordinal parameter α ≥ 1 — for every set S with Hartogs number less than ωα, S is well-orderable. +As the ordinal parameter is increased, these approximate the full axiom of choice more and more closely. + +Other choice axioms weaker than axiom of choice include the Boolean prime ideal theorem and the axiom of uniformization. The former is equivalent in ZF to Tarski's 1930 ultrafilter lemma: every filter is a subset of some ultrafilter. + +Results requiring AC (or weaker forms) but weaker than it +One of the most interesting aspects of the axiom of choice is the large number of places in mathematics that it shows up. Here are some statements that require the axiom of choice in the sense that they are not provable from ZF but are provable from ZFC (ZF plus AC). Equivalently, these statements are true in all models of ZFC but false in some models of ZF. + +Set theory +The ultrafilter lemma (with ZF) can be used to prove the Axiom of choice for finite sets: Given and a collection of non-empty sets, their product is not empty. +The union of any countable family of countable sets is countable (this requires countable choice but not the full axiom of choice). +If the set A is infinite, then there exists an injection from the natural numbers N to A (see Dedekind infinite). +Eight definitions of a finite set are equivalent. +Every infinite game in which is a Borel subset of Baire space is determined. +Measure theory +The Vitali theorem on the existence of non-measurable sets, which states that there exists a subset of the real numbers that is not Lebesgue measurable. +There exist Lebesgue-measurable subsets of the real numbers that are not Borel sets. That is, the Borel σ-algebra on the real numbers (which is generated by all real intervals) is distinct from the Lebesgue-measure σ-algebra on the real numbers. +The Hausdorff paradox. +The Banach–Tarski paradox. +Algebra +Every field has an algebraic closure. +Every field extension has a transcendence basis. +Every infinite-dimensional vector space contains an infinite linearly independent subset (this requires dependent choice, but not the full axiom of choice). +Stone's representation theorem for Boolean algebras needs the Boolean prime ideal theorem. +The Nielsen–Schreier theorem, that every subgroup of a free group is free. +The additive groups of R and C are isomorphic. +Functional analysis +The Hahn–Banach theorem in functional analysis, allowing the extension of linear functionals +The theorem that every Hilbert space has an orthonormal basis. +The Banach–Alaoglu theorem about compactness of sets of functionals. +The Baire category theorem about complete metric spaces, and its consequences, such as the open mapping theorem and the closed graph theorem. +On every infinite-dimensional topological vector space there is a discontinuous linear map. +General topology +A uniform space is compact if and only if it is complete and totally bounded. +Every Tychonoff space has a Stone–Čech compactification. +Mathematical logic +Gödel's completeness theorem for first-order logic: every consistent set of first-order sentences has a completion. That is, every consistent set of first-order sentences can be extended to a maximal consistent set. +The compactness theorem: If is a set of first-order (or alternatively, zero-order) sentences such that every finite subset of has a model, then has a model. + +Possibly equivalent implications of AC +There are several historically important set-theoretic statements implied by AC whose equivalence to AC is open. The partition principle, which was formulated before AC itself, was cited by Zermelo as a justification for believing AC. In 1906, Russell declared PP to be equivalent, but whether the partition principle implies AC is still the oldest open problem in set theory, and the equivalences of the other statements are similarly hard old open problems. In every known model of ZF where choice fails, these statements fail too, but it is unknown if they can hold without choice. + +Set theory +Partition principle: if there is a surjection from A to B, there is an injection from B to A. Equivalently, every partition P of a set S is less than or equal to S in size. +Converse Schröder–Bernstein theorem: if two sets have surjections to each other, they are equinumerous. +Weak partition principle: if there is a injection and a surjection from A to B, then A and B are equinumerous. Equivalently, a partition of a set S cannot be strictly larger than S. If WPP holds, this already implies the existence of a non-measurable set. Each of the previous three statements is implied by the preceding one, but it is unknown if any of these implications can be reversed. +There is no infinite decreasing sequence of cardinals. The equivalence was conjectured by Schoenflies in 1905. +Abstract algebra +Hahn embedding theorem: Every ordered abelian group G order-embeds as a subgroup of the additive group endowed with a lexicographical order, where Ω is the set of Archimedean equivalence classes of G. This equivalence was conjectured by Hahn in 1907. + +Stronger forms of the negation of AC +If we abbreviate by BP the claim that every set of real numbers has the property of Baire, then BP is stronger than ¬AC, which asserts the nonexistence of any choice function on perhaps only a single set of nonempty sets. Strengthened negations may be compatible with weakened forms of AC. For example, ZF + DC + BP is consistent, if ZF is. + +It is also consistent with ZF + DC that every set of reals is Lebesgue measurable; however, this consistency result, due to Robert M. Solovay, cannot be proved in ZFC itself, but requires a mild large cardinal assumption (the existence of an inaccessible cardinal). The much stronger axiom of determinacy, or AD, implies that every set of reals is Lebesgue measurable, has the property of Baire, and has the perfect set property (all three of these results are refuted by AC itself). ZF + DC + AD is consistent provided that a sufficiently strong large cardinal axiom is consistent (the existence of infinitely many Woodin cardinals). + +Quine's system of axiomatic set theory, New Foundations (NF), takes its name from the title ("New Foundations for Mathematical Logic") of the 1937 article which introduced it. In the NF axiomatic system, the axiom of choice can be disproved. + +Statements consistent with the negation of AC +There are models of Zermelo-Fraenkel set theory in which the axiom of choice is false. We shall abbreviate "Zermelo-Fraenkel set theory plus the negation of the axiom of choice" by ZF¬C. For certain models of ZF¬C, it is possible to prove the negation of some standard facts. +Any model of ZF¬C is also a model of ZF, so for each of the following statements, there exists a model of ZF in which that statement is true. + +There is a set that can be partitioned into strictly more equivalence classes than the original set has elements, and a function whose domain is strictly smaller than its range. In fact, this is the case in all known models. +There is a function f from the real numbers to the real numbers such that f is not continuous at a, but f is sequentially continuous at a, i.e., for any sequence {xn} converging to a, limn f(xn)=f(a). +There is an infinite set of real numbers without a countably infinite subset. +The real numbers are a countable union of countable sets. This does not imply that the real numbers are countable: As pointed out above, to show that a countable union of countable sets is itself countable requires the Axiom of countable choice. +There is a field with no algebraic closure. +In all models of ZF¬C there is a vector space with no basis. +There is a vector space with two bases of different cardinalities. +There is a free complete boolean algebra on countably many generators. +There is a set that cannot be linearly ordered. +There exists a model of ZF¬C in which every set in Rn is measurable. Thus it is possible to exclude counterintuitive results like the Banach–Tarski paradox which are provable in ZFC. Furthermore, this is possible whilst assuming the Axiom of dependent choice, which is weaker than AC but sufficient to develop most of real analysis. +In all models of ZF¬C, the generalized continuum hypothesis does not hold. + +For proofs, see . + +Additionally, by imposing definability conditions on sets (in the sense of descriptive set theory) one can often prove restricted versions of the axiom of choice from axioms incompatible with general choice. This appears, for example, in the Moschovakis coding lemma. + +Axiom of choice in type theory + +In type theory, a different kind of statement is known as the axiom of choice. This form begins with two types, σ and τ, and a relation R between objects of type σ and objects of type τ. The axiom of choice states that if for each x of type σ there exists a y of type τ such that R(x,y), then there is a function f from objects of type σ to objects of type τ such that R(x,f(x)) holds for all x of type σ: + +Unlike in set theory, the axiom of choice in type theory is typically stated as an axiom scheme, in which R varies over all formulas or over all formulas of a particular logical form. + +Quotations + +This is a joke: although the three are all mathematically equivalent, many mathematicians find the axiom of choice to be intuitive, the well-ordering principle to be counterintuitive, and Zorn's lemma to be too complex for any intuition. + +The observation here is that one can define a function to select from an infinite number of pairs of shoes, for example by choosing the left shoe from each pair. Without the axiom of choice, one cannot assert that such a function exists for pairs of socks, because left and right socks are (presumably) indistinguishable. + +Polish-American mathematician Jan Mycielski relates this anecdote in a 2006 article in the Notices of the AMS. + +This quote comes from the famous April Fools' Day article in the computer recreations column of the Scientific American, April 1989. + +Notes + +References + + + + + + + Per Martin-Löf, "100 years of Zermelo's axiom of choice: What was the problem with it?", in Logicism, Intuitionism, and Formalism: What Has Become of Them?, Sten Lindström, Erik Palmgren, Krister Segerberg, and Viggo Stoltenberg-Hansen, editors (2008). + + , available as a Dover Publications reprint, 2013, . + +Herman Rubin, Jean E.

He was also the leader of an empire consisting of Huns, Ostrogoths, Alans, and Bulgars, among others, in Central and Eastern Europe. + +During his reign, he was one of the most feared enemies of the Western and Eastern Roman Empires. He crossed the Danube twice and plundered the Balkans but was unable to take Constantinople. In 441, he led an invasion of the Eastern Roman (Byzantine) Empire, the success of which emboldened him to invade the West. He also attempted to conquer Roman Gaul (modern France), crossing the Rhine in 451 and marching as far as Aurelianum (Orléans), before being stopped in the Battle of the Catalaunian Plains. + +He subsequently invaded Italy, devastating the northern provinces, but was unable to take Rome. He planned for further campaigns against the Romans but died in 453. After Attila's death, his close adviser, Ardaric of the Gepids, led a Germanic revolt against Hunnic rule, after which the Hunnic Empire quickly collapsed. Attila lived on as a character in Germanic heroic legend. + +Etymology + +Many scholars have argued that the name Attila derives from East Germanic origin; Attila is formed from the Gothic or Gepidic noun atta, "father", by means of the diminutive suffix -ila, meaning "little father", compare Wulfila from wulfs "wolf" and -ila, i.e. "little wolf". The Gothic etymology was first proposed by Jacob and Wilhelm Grimm in the early 19th century. Maenchen-Helfen notes that this derivation of the name "offers neither phonetic nor semantic difficulties", and Gerhard Doerfer notes that the name is simply correct Gothic. Alexander Savelyev and Choongwon Jeong (2020) similarly state that Attila's name "must have been Gothic in origin." The name has sometimes been interpreted as a Germanization of a name of Hunnic origin. + +Other scholars have argued for a Turkic origin of the name. Omeljan Pritsak considered Ἀττίλα (Attíla) a composite title-name which derived from Turkic *es (great, old), and *til (sea, ocean), and the suffix /a/. The stressed back syllabic til assimilated the front member es, so it became *as. It is a nominative, in form of attíl- (< *etsíl < *es tíl) with the meaning "the oceanic, universal ruler". J. J. Mikkola connected it with Turkic āt (name, fame). + +As another Turkic possibility, H. Althof (1902) considered it was related to Turkish atli (horseman, cavalier), or Turkish at (horse) and dil (tongue). Maenchen-Helfen argues that Pritsak's derivation is "ingenious but for many reasons unacceptable", while dismissing Mikkola's as "too farfetched to be taken seriously". M. Snædal similarly notes that none of these proposals has achieved wide acceptance. + +Criticizing the proposals of finding Turkic or other etymologies for Attila, Doerfer notes that King George VI of the United Kingdom had a name of Greek origin, and Süleyman the Magnificent had a name of Arabic origin, yet that does not make them Greeks or Arabs: it is therefore plausible that Attila would have a name not of Hunnic origin. Historian Hyun Jin Kim, however, has argued that the Turkic etymology is "more probable". + +M. Snædal, in a paper that rejects the Germanic derivation but notes the problems with the existing proposed Turkic etymologies, argues that Attila's name could have originated from Turkic-Mongolian at, adyy/agta (gelding, warhorse) and Turkish atlı (horseman, cavalier), meaning "possessor of geldings, provider of warhorses". + +Historiography and source + +The historiography of Attila is faced with a major challenge, in that the only complete sources are written in Greek and Latin by the enemies of the Huns. Attila's contemporaries left many testimonials of his life, but only fragments of these remain. Priscus was a Byzantine diplomat and historian who wrote in Greek, and he was both a witness to and an actor in the story of Attila, as a member of the embassy of Theodosius II at the Hunnic court in 449. He was obviously biased by his political position, but his writing is a major source for information on the life of Attila, and he is the only person known to have recorded a physical description of him. He wrote a history of the late Roman Empire in eight books covering the period from 430 to 476. + +Only fragments of Priscus' work remain. It was cited extensively by 6th-century historians Procopius and Jordanes, especially in Jordanes' The Origin and Deeds of the Goths, which contains numerous references to Priscus's history, and it is also an important source of information about the Hunnic empire and its neighbors. He describes the legacy of Attila and the Hunnic people for a century after Attila's death. Marcellinus Comes, a chancellor of Justinian during the same era, also describes the relations between the Huns and the Eastern Roman Empire. + +Numerous ecclesiastical writings contain useful but scattered information, sometimes difficult to authenticate or distorted by years of hand-copying between the 6th and 17th centuries. The Hungarian writers of the 12th century wished to portray the Huns in a positive light as their glorious ancestors, and so repressed certain historical elements and added their own legends. + +The literature and knowledge of the Huns themselves was transmitted orally, by means of epics and chanted poems that were handed down from generation to generation. Indirectly, fragments of this oral history have reached us via the literature of the Scandinavians and Germans, neighbors of the Huns who wrote between the 9th and 13th centuries. Attila is a major character in many Medieval epics, such as the Nibelungenlied, as well as various Eddas and sagas. + +Archaeological investigation has uncovered some details about the lifestyle, art, and warfare of the Huns. There are a few traces of battles and sieges, but the tomb of Attila and the location of his capital have not yet been found. + +Early life and background + +The Huns were a group of Eurasian nomads, appearing from east of the Volga, who migrated further into Western Europe c. 370 and built up an enormous empire there. Their main military techniques were mounted archery and javelin throwing. They were in the process of developing settlements before their arrival in Western Europe, yet the Huns were a society of pastoral warriors whose primary form of nourishment was meat and milk, products of their herds. + +The origin and language of the Huns has been the subject of debate for centuries. According to some theories, their leaders at least may have spoken a Turkic language, perhaps closest to the modern Chuvash language. According to the Encyclopedia of European Peoples, "the Huns, especially those who migrated to the west, may have been a combination of central Asian Turkic, Mongolic, and Ugric stocks". + +Attila's father Mundzuk was the brother of kings Octar and Ruga, who reigned jointly over the Hunnic empire in the early fifth century. This form of diarchy was recurrent with the Huns, but historians are unsure whether it was institutionalized, merely customary, or an occasional occurrence. His family was from a noble lineage, but it is uncertain whether they constituted a royal dynasty. Attila's birthdate is debated; journalist Éric Deschodt and writer Herman Schreiber have proposed a date of 395. However, historian Iaroslav Lebedynsky and archaeologist Katalin Escher prefer an estimate between the 390s and the first decade of the fifth century. Several historians have proposed 406 as the date. + +Attila grew up in a rapidly changing world. His people were nomads who had only recently arrived in Europe. They crossed the Volga river during the 370s and annexed the territory of the Alans, then attacked the Gothic kingdom between the Carpathian mountains and the Danube. They were a very mobile people, whose mounted archers had acquired a reputation for invincibility, and the Germanic tribes seemed unable to withstand them. Vast populations fleeing the Huns moved from Germania into the Roman Empire in the west and south, and along the banks of the Rhine and Danube. In 376, the Goths crossed the Danube, initially submitting to the Romans but soon rebelling against Emperor Valens, whom they killed in the Battle of Adrianople in 378. Large numbers of Vandals, Alans, Suebi, and Burgundians crossed the Rhine and invaded Roman Gaul on December 31, 406 to escape the Huns. The Roman Empire had been split in half since 395 and was ruled by two distinct governments, one based in Ravenna in the West, and the other in Constantinople in the East. The Roman Emperors, both East and West, were generally from the Theodosian family in Attila's lifetime (despite several power struggles). + +The Huns dominated a vast territory with nebulous borders determined by the will of a constellation of ethnically varied peoples. Some were assimilated to Hunnic nationality, whereas many retained their own identities and rulers but acknowledged the suzerainty of the king of the Huns. The Huns were also the indirect source of many of the Romans' problems, driving various Germanic tribes into Roman territory, yet relations between the two empires were cordial: the Romans used the Huns as mercenaries against the Germans and even in their civil wars. Thus, the usurper Joannes was able to recruit thousands of Huns for his army against Valentinian III in 424. It was Aëtius, later Patrician of the West, who managed this operation. They exchanged ambassadors and hostages, the alliance lasting from 401 to 450 and permitting the Romans numerous military victories. The Huns considered the Romans to be paying them tribute, whereas the Romans preferred to view this as payment for services rendered. The Huns had become a great power by the time that Attila came of age during the reign of his uncle Ruga, to the point that Nestorius, the Patriarch of Constantinople, deplored the situation with these words: "They have become both masters and slaves of the Romans". + +Campaigns against the Eastern Roman Empire + +The death of Rugila (also known as Rua or Ruga) in 434 left the sons of his brother Mundzuk, Attila and Bleda, in control of the united Hun tribes. At the time of the two brothers' accession, the Hun tribes were bargaining with Eastern Roman Emperor Theodosius II's envoys for the return of several renegades who had taken refuge within the Eastern Roman Empire, possibly Hunnic nobles who disagreed with the brothers' assumption of leadership. + +The following year, Attila and Bleda met with the imperial legation at Margus (Požarevac), all seated on horseback in the Hunnic manner, and negotiated an advantageous treaty. The Romans agreed to return the fugitives, to double their previous tribute of 350 Roman pounds (c. 115 kg) of gold, to open their markets to Hunnish traders, and to pay a ransom of eight solidi for each Roman taken prisoner by the Huns. The Huns, satisfied with the treaty, decamped from the Roman Empire and returned to their home in the Great Hungarian Plain, perhaps to consolidate and strengthen their empire. Theodosius used this opportunity to strengthen the walls of Constantinople, building the city's first sea wall, and to build up his border defenses along the Danube. + +The Huns remained out of Roman sight for the next few years while they invaded the Sassanid Empire. They were defeated in Armenia by the Sassanids, abandoned their invasion, and turned their attentions back to Europe. In 440, they reappeared in force on the borders of the Roman Empire, attacking the merchants at the market on the north bank of the Danube that had been established by the treaty of 435. + +Crossing the Danube, they laid waste to the cities of Illyricum and forts on the river, including (according to Priscus) Viminacium, a city of Moesia. Their advance began at Margus, where they demanded that the Romans turn over a bishop who had retained property that Attila regarded as his. While the Romans discussed the bishop's fate, he slipped away secretly to the Huns and betrayed the city to them. + +While the Huns attacked city-states along the Danube, the Vandals (led by Geiseric) captured the Western Roman province of Africa and its capital of Carthage. Africa was the richest province of the Western Empire and a main source of food for Rome. The Sassanid Shah Yazdegerd II invaded Armenia in 441. + +The Romans stripped the Balkan area of forces, sending them to Sicily in order to mount an expedition against the Vandals in Africa. This left Attila and Bleda a clear path through Illyricum into the Balkans, which they invaded in 441. The Hunnish army sacked Margus and Viminacium, and then took Singidunum (Belgrade) and Sirmium. During 442, Theodosius recalled his troops from Sicily and ordered a large issue of new coins to finance operations against the Huns. He believed that he could defeat the Huns and refused the Hunnish kings' demands. + +Attila responded with a campaign in 443. For the first time (as far as the Romans knew) his forces were equipped with battering rams and rolling siege towers, with which they successfully assaulted the military centers of Ratiara and Naissus (Niš) and massacred the inhabitants. Priscus said "When we arrived at Naissus we found the city deserted, as though it had been sacked; only a few sick persons lay in the churches. We halted at a short distance from the river, in an open space, for all the ground adjacent to the bank was full of the bones of men slain in war." + +Advancing along the Nišava River, the Huns next took Serdica (Sofia), Philippopolis (Plovdiv), and Arcadiopolis (Lüleburgaz). They encountered and destroyed a Roman army outside Constantinople but were stopped by the double walls of the Eastern capital. They defeated a second army near Callipolis (Gelibolu). + +Theodosius, unable to make effective armed resistance, admitted defeat, sending the Magister militum per Orientem Anatolius to negotiate peace terms. The terms were harsher than the previous treaty: the Emperor agreed to hand over 6,000 Roman pounds (c. 2000 kg) of gold as punishment for having disobeyed the terms of the treaty during the invasion; the yearly tribute was tripled, rising to 2,100 Roman pounds (c. 700 kg) in gold; and the ransom for each Roman prisoner rose to 12 solidi. + +Their demands were met for a time, and the Hun kings withdrew into the interior of their empire. Bleda died following the Huns' withdrawal from Byzantium (probably around 445). Attila then took the throne for himself, becoming the sole ruler of the Huns. + +Solitary kingship + +In 447, Attila again rode south into the Eastern Roman Empire through Moesia. The Roman army, under Gothic magister militum Arnegisclus, met him in the Battle of the Utus and was defeated, though not without inflicting heavy losses. The Huns were left unopposed and rampaged through the Balkans as far as Thermopylae. + +Constantinople itself was saved by the Isaurian troops of magister militum per Orientem Zeno and protected by the intervention of prefect Constantinus, who organized the reconstruction of the walls that had been previously damaged by earthquakes and, in some places, to construct a new line of fortification in front of the old. Callinicus, in his Life of Saint Hypatius, wrote: + +In the west + +In 450, Attila proclaimed his intent to attack the Visigoth kingdom of Toulouse by making an alliance with Emperor Valentinian III. He had previously been on good terms with the Western Roman Empire and its influential general Flavius Aëtius. Aëtius had spent a brief exile among the Huns in 433, and the troops that Attila provided against the Goths and Bagaudae had helped earn him the largely honorary title of magister militum in the west. The gifts and diplomatic efforts of Geiseric, who opposed and feared the Visigoths, may also have influenced Attila's plans. + +However, Valentinian's sister was Honoria, who had sent the Hunnish king a plea for help—and her engagement ring—in order to escape her forced betrothal to a Roman senator in the spring of 450. Honoria may not have intended a proposal of marriage, but Attila chose to interpret her message as such. He accepted, asking for half of the western Empire as dowry. + +When Valentinian discovered the plan, only the influence of his mother Galla Placidia convinced him to exile Honoria, rather than killing her. He also wrote to Attila, strenuously denying the legitimacy of the supposed marriage proposal. Attila sent an emissary to Ravenna to proclaim that Honoria was innocent, that the proposal had been legitimate, and that he would come to claim what was rightfully his. + +Attila interfered in a succession struggle after the death of a Frankish ruler. Attila supported the elder son, while Aëtius supported the younger. (The location and identity of these kings is not known and subject to conjecture.) Attila gathered his vassals—Gepids, Ostrogoths, Rugians, Scirians, Heruls, Thuringians, Alans, Burgundians, among others—and began his march west. In 451, he arrived in Belgica with an army exaggerated by Jordanes to half a million strong. + +On April 7, he captured Metz. Other cities attacked can be determined by the hagiographic vitae written to commemorate their bishops: Nicasius was slaughtered before the altar of his church in Rheims; Servatus is alleged to have saved Tongeren with his prayers, as Saint Genevieve is said to have saved Paris. Lupus, bishop of Troyes, is also credited with saving his city by meeting Attila in person. + +Aëtius moved to oppose Attila, gathering troops from among the Franks, the Burgundians, and the Celts. A mission by Avitus and Attila's continued westward advance convinced the Visigoth king Theodoric I (Theodorid) to ally with the Romans. The combined armies reached Orléans ahead of Attila, thus checking and turning back the Hunnish advance. Aëtius gave chase and caught the Huns at a place usually assumed to be near Catalaunum (modern Châlons-en-Champagne). Attila decided to fight the Romans on plains where he could use his cavalry. + +The two armies clashed in the Battle of the Catalaunian Plains, the outcome of which is commonly considered to be a strategic victory for the Visigothic-Roman alliance. Theodoric was killed in the fighting, and Aëtius failed to press his advantage, according to Edward Gibbon and Edward Creasy, because he feared the consequences of an overwhelming Visigothic triumph as much as he did a defeat. From Aëtius' point of view, the best outcome was what occurred: Theodoric died, Attila was in retreat and disarray, and the Romans had the benefit of appearing victorious. + +Invasion of Italy and death + +Attila returned in 452 to renew his marriage claim with Honoria, invading and ravaging Italy along the way. Communities became established in what would later become Venice as a result of these attacks when the residents fled to small islands in the Venetian Lagoon. His army sacked numerous cities and razed Aquileia so completely that it was afterwards hard to recognize its original site. Aëtius lacked the strength to offer battle, but managed to harass and slow Attila's advance with only a shadow force. Attila finally halted at the River Po. By this point, disease and starvation may have taken hold in Attila's camp, thus hindering his war efforts and potentially contributing to the cessation of invasion. + +Emperor Valentinian III sent three envoys, the high civilian officers Gennadius Avienus and Trigetius, as well as the Bishop of Rome Leo I, who met Attila at Mincio in the vicinity of Mantua and obtained from him the promise that he would withdraw from Italy and negotiate peace with the Emperor. Prosper of Aquitaine gives a short description of the historic meeting, but gives all the credit to Leo for the successful negotiation. Priscus reports that superstitious fear of the fate of Alaric gave him pause—as Alaric died shortly after sacking Rome in 410. + +Italy had suffered from a terrible famine in 451 and her crops were faring little better in 452. Attila's devastating invasion of the plains of northern Italy this year did not improve the harvest. To advance on Rome would have required supplies which were not available in Italy, and taking the city would not have improved Attila's supply situation. Therefore, it was more profitable for Attila to conclude peace and retreat to his homeland. + +Furthermore, an East Roman force had crossed the Danube under the command of another officer also named Aetius—who had participated in the Council of Chalcedon the previous year—and proceeded to defeat the Huns who had been left behind by Attila to safeguard their home territories. Attila, hence, faced heavy human and natural pressures to retire "from Italy without ever setting foot south of the Po". As Hydatius writes in his Chronica Minora: + +Death + +In the Eastern Roman Empire, Emperor Marcian succeeded Theodosius II, and stopped paying tribute to the Huns. Attila withdrew from Italy to his palace across the Danube, while making plans to strike at Constantinople once more to reclaim tribute. + +However, he died in the early months of 453. + +The conventional account from Priscus says that Attila was at a feast celebrating his latest marriage, this time to the beautiful young Ildico (the name suggests Gothic or Ostrogoth origins). In the midst of the revels, however, he suffered severe bleeding and died. He may have had a nosebleed and choked to death in a stupor. Or he may have succumbed to internal bleeding, possibly due to ruptured esophageal varices. Esophageal varices are dilated veins that form in the lower part of the esophagus, often caused by years of excessive alcohol consumption; they are fragile and can easily rupture, leading to death by hemorrhage. + +Another account of his death was first recorded 80 years after the events by Roman chronicler Marcellinus Comes. It reports that "Attila, King of the Huns and ravager of the provinces of Europe, was pierced by the hand and blade of his wife". One modern analyst suggests that he was assassinated, but most reject these accounts as no more than hearsay, preferring instead the account given by Attila's contemporary Priscus, recounted in the 6th century by Jordanes: + +Descendants + +Attila's sons Ellac, Dengizich and Ernak, "in their rash eagerness to rule they all alike destroyed his empire". They "were clamoring that the nations should be divided among them equally and that warlike kings with their peoples should be apportioned to them by lot like a family estate". Against the treatment as "slaves of the basest condition" a Germanic alliance led by the Gepid ruler Ardaric (who was noted for great loyalty to Attila) revolted and fought with the Huns in Pannonia in the Battle of Nedao 454 AD. Attila's eldest son Ellac was killed in that battle. Attila's sons "regarding the Goths as deserters from their rule, came against them as though they were seeking fugitive slaves", attacked Ostrogothic co-ruler Valamir (who also fought alongside Ardaric and Attila at the Catalaunian Plains), but were repelled, and some group of Huns moved to Scythia (probably those of Ernak). His brother Dengizich attempted a renewed invasion across the Danube in 468 AD, but was defeated at the Battle of Bassianae by the Ostrogoths. Dengizich was killed by Roman-Gothic general Anagast the following year, after which the Hunnic dominion ended. + +Attila's many children and relatives are known by name and some even by deeds, but soon valid genealogical sources all but dried up, and there seems to be no verifiable way to trace Attila's descendants. This has not stopped many genealogists from attempting to reconstruct a valid line of descent for various medieval rulers. One of the most credible claims has been that of the Nominalia of the Bulgarian khans for mythological Avitohol and Irnik from the Dulo clan of the Bulgars. The Hungarian Árpád dynasty also claimed to be a direct descendant of Attila. Medieval Hungarian chronicles from the Hungarian royal court like Gesta Hungarorum, Gesta Hunnorum et Hungarorum, Chronicon Pictum, Buda Chronicle, Chronica Hungarorum claimed that the Árpád dynasty and the Aba clan are the descendants of Attila. + +Appearance and character + +There is no surviving first-hand account of Attila's appearance, but there is a possible second-hand source provided by Jordanes, who cites a description given by Priscus. + +Some scholars have suggested that these features are typically East Asian, because in combination they fit the physical type of people from Eastern Asia, so Attila's ancestors may have come from there. Other historians have suggested that the same features may have been typical of some Scythian people. + +Later folklore and iconography + +The name has many variants in several languages: Atli and Atle in Old Norse; Etzel in Middle High German (Nibelungenlied); Ætla in Old English; Attila, Atilla, and Etele in Hungarian (Attila is the most popular); Attila, Atilla, Atilay, or Atila in Turkish; and Adil and Edil in Kazakh or Adil ("same/similar") or Edil ("to use") in Mongolian. + +Attila and Hun tradition in the medieval Hungarian Royal Court +The basic premise of the Hungarian medieval chronicle tradition that the Huns, i.e. the Hungarians coming out twice from Scythia, the guiding principle of the chronicles was the Hun-Hungarian continuity. The Hungarian state founder royal dynasty, the Árpád dynasty claimed to be a direct descendant of the great Hun leader Attila. Medieval Hungarian chronicles claimed that Grand Prince Árpád of Hungary was the descendants of Attila. + +Árpád, Grand Prince of the Hungarians says in the Gesta Hungarorum: + +King Matthias of Hungary (1458–1490) was happy to be described as "the second Attila". The Chronica Hungarorum by Johannes Thuróczy set the goal of glorifying Attila, which was undeservedly neglected, moreover, he introduced the famous "Scourge of God" characterization to the later Hungarian writers, because the earlier chronicles remained hidden for a long time. Thuróczy worked hard to endear Attila, the Hun king with an effort far surpassing his predecessor chroniclers. He made Attila a model for his victorious ruler, King Matthias of Hungary who had Attila's abilities, with this he almost brought "the hammer of the world" to life. + +Legends about Attila and the sword of Mars +Jordanes embellished the report of Priscus, reporting that Attila had possessed the "Holy War Sword of the Scythians", which was given to him by Mars and made him a "prince of the entire world". + +Lampert of Hersfeld's contemporary chronicles report that shortly before the year 1071, the Sword of Attila had been presented to Otto of Nordheim by the exiled queen of Hungary, Anastasia of Kiev. This sword, a cavalry sabre now in the Kunsthistorisches Museum in Vienna, appears to be the work of Hungarian goldsmiths of the ninth or tenth century. + +Legends about Attila and his meeting with Pope Leo I +An anonymous chronicler of the medieval period represented the meeting of Pope Leo and Atilla as attended also by Saint Peter and Saint Paul, "a miraculous tale calculated to meet the taste of the time" This apotheosis was later portrayed artistically by the Renaissance artist Raphael and sculptor Algardi, whom eighteenth-century historian Edward Gibbon praised for establishing "one of the noblest legends of ecclesiastical tradition". + +According to a version of this narrative related in the Chronicon Pictum, a mediaeval Hungarian chronicle, the Pope promised Attila that if he left Rome in peace, one of his successors would receive a holy crown (which has been understood as referring to the Holy Crown of Hungary). + +Attila in Germanic heroic legend +Some histories and chronicles describe Attila as a great and noble king, and he plays major roles in three Norse texts: Atlakviða, Volsunga saga, and Atlamál. The Polish Chronicle represents Attila's name as Aquila. + +Frutolf of Michelsberg and Otto of Freising pointed out that some songs as "vulgar fables" and made Theoderic the Great, Attila and Ermanaric contemporaries, when any reader of Jordanes knew that this was not the case. This refers to the so-called historical poems about Dietrich von Bern (Theoderic), in which Etzel (German for Attila) is Dietrich's refuge in exile from his wicked uncle Ermenrich (Ermanaric). Etzel is most prominent in the poems Dietrichs Flucht and the Rabenschlacht. Etzel also appears as Kriemhild's second noble husband in the Nibelungenlied, in which Kriemhild causes the destruction of both the Hunnish kingdom and that of her Burgundian relatives. + +Early modern and modern reception +In 1812, Ludwig van Beethoven conceived the idea of writing an opera about Attila and approached August von Kotzebue to write the libretto. It was, however, never written. In 1846, Giuseppe Verdi wrote the opera, loosely based on episodes in Attila's invasion of Italy. + +In World War I, Allied propaganda referred to Germans as the "Huns", based on a 1900 speech by Emperor Wilhelm II praising Attila the Hun's military prowess, according to Jawaharlal Nehru's Glimpses of World History. Der Spiegel commented on 6 November 1948, that the Sword of Attila was hanging menacingly over Austria. + +American writer Cecelia Holland wrote The Death of Attila (1973), a historical novel in which Attila appears as a powerful background figure whose life and death deeply affect the protagonists, a young Hunnic warrior and a Germanic one. + +In modern Hungary and in Turkey, "Attila" and its Turkish variation "Atilla" are commonly used as a male first name. In Hungary, several public places are named after Attila; for instance, in Budapest there are 10 Attila Streets, one of which is an important street behind the Buda Castle. When the Turkish Armed Forces invaded Cyprus in 1974, the operations were named after Attila ("The Attila Plan"). + +The 1954 Universal International film Sign of the Pagan starred Jack Palance as Attila. + +Depictions of Attila + +See also + + Onegesius + Bleda + Mundzuk + +Notes + +Sources + +External links + + + + Works about Attila at Project Gutenberg + + + +5th-century Hunnic kings +5th-century monarchs in Europe +406 births +453 deaths +Deaths from choking +Genocide perpetrators +Attilid dynasty +The Aegean Sea is an elongated embayment of the Mediterranean Sea between Europe and Asia. It is located between the Balkans and Anatolia, and covers an area of some . In the north, the Aegean is connected to the Marmara Sea, which in turn connects to the Black Sea, by the straits of the Dardanelles and the Bosphorus, respectively. The Aegean Islands are located within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea reaches a maximum depth of to the west of Karpathos. The Thracian Sea and the Sea of Crete are main subdivisions of the Aegean Sea. + +The Aegean Islands can be divided into several island groups, including the Dodecanese, the Cyclades, the Sporades, the Saronic islands and the North Aegean Islands, as well as Crete and its surrounding islands. The Dodecanese, located to the southeast, includes the islands of Rhodes, Kos, and Patmos; the islands of Delos and Naxos are within the Cyclades to the south of the sea. Lesbos is part of the North Aegean Islands. Euboea, the second-largest island in Greece, is located in the Aegean, despite being administered as part of Central Greece. Nine out of twelve of the Administrative regions of Greece border the sea, along with the Turkish provinces of Edirne, Çanakkale, Balıkesir, Izmir, Aydın and Muğla to the east of the sea. Various Turkish islands in the sea are Imbros, Tenedos, Cunda Island, and the Foça Islands. + +The Aegean Sea has been historically important, especially in regards to the civilization of Ancient Greece, who inhabited the area around the coast of the Aegean and the Aegean islands. The Aegean islands facilitated contact between the people of the area and between Europe and Asia. Along with the Greeks, Thracians lived among the northern coast. The Romans conquered the area under the Roman Empire, and later the Byzantine Empire held it against advances by the First Bulgarian Empire. The Fourth Crusade weakened Byzantine control of the area, and it was eventually conquered by the Ottoman Empire, with the exception of Crete, which was a Venetian colony until 1669. The Greek War of Independence allowed a Greek state on the coast of the Aegean from 1829 onwards. The Ottoman Empire held a presence over the sea for over 500 years, until it was replaced by modern Turkey. + +The rocks making up the floor of the Aegean are mainly limestone, though often greatly altered by volcanic activity that has convulsed the region in relatively recent geologic times. Of particular interest are the richly coloured sediments in the region of the islands of Santorini and Milos, in the south Aegean. Notable cities on the Aegean coastline include Athens, Thessaloniki, Volos, Kavala and Heraklion in Greece, and İzmir and Bodrum in Turkey. + +A number of issues concerning sovereignty within the Aegean Sea are disputed between Greece and Turkey. The Aegean dispute has had a large effect on Greek-Turkish relations since the 1970s. Issues include the delimitation of territorial waters, national airspace, exclusive economic zones and flight information regions. + +Name and etymology +The name Aegaeus, used by Late Latin authors, referred to Aegeus, who was said to have jumped into that sea to drown himself (rather than throw himself from the Athenian acropolis, as told by some Greek authors). He was the father of Theseus, the mythical king and founder-hero of Athens. Aegeus had told Theseus to put up white sails when returning if he was successful in killing the Minotaur. When Theseus returned, he forgot these instructions, and Aegeus thought his son had died, so he drowned himself in the sea. + +The sea was known in Latin as Mare Aegaeum while under the control of the Roman Empire. The Venetians, who ruled many Greek islands in the High and Late Middle Ages, popularized the name Archipelago (, meaning "main sea" or "chief sea"), a name that held on in many European countries until the early modern period. In South Slavic languages, the Aegean is called White Sea (; ; ). The Turkish name for the sea is Ege Denizi, which is derived from the Greek name. + +Geography +The Aegean Sea is an elongated embayment of the Mediterranean Sea and covers about in area, measuring about longitudinally and latitudinal. The sea's maximum depth is , located at a point west of Karpathos. The Aegean Islands are found within its waters, with the following islands delimiting the sea on the south, generally from west to east: Kythera, Antikythera, Crete, Kasos, Karpathos and Rhodes. The Anatolian peninsula marks the eastern boundary of the sea, while the Greek mainland marks the west. Several seas are contained within the Aegean Sea; the Thracian Sea is a section of the Aegean located to the north, the Icarian Sea to the east, the Myrtoan Sea to the west, while the Sea of Crete is the southern section. + +The Greek regions that border the sea, in alphabetical order, are Attica, Central Greece, Central Macedonia, Crete, Eastern Macedonia and Thrace, North Aegean, Peloponnese, South Aegean, and Thessaly. The traditional Greek region of Macedonia also borders the sea, to the north. + +The Aegean Islands, which almost all belong to Greece, can be divided into seven groups: + Northeastern Aegean Islands, which lie in the Thracian Sea + East Aegean Islands (Euboea) + Northern Sporades + Cyclades + Saronic Islands (or Argo-Saronic Islands) + Dodecanese (or Southern Sporades) + Crete + +Many of the Aegean islands or island chains, are geographically extensions of the mountains on the mainland. One chain extends across the sea to Chios, another extends across Euboea to Samos, and a third extends across the Peloponnese and Crete to Rhodes, dividing the Aegean from the Mediterranean. + +The bays and gulfs of the Aegean beginning at the South and moving clockwise include on Crete, the Mirabello, Almyros, Souda and Chania bays or gulfs, on the mainland the Myrtoan Sea to the west with the Argolic Gulf, the Saronic Gulf northwestward, the Petalies Gulf which connects with the South Euboic Sea, the Pagasetic Gulf which connects with the North Euboic Sea, the Thermian Gulf northwestward, the Chalkidiki Peninsula including the Cassandra and the Singitic Gulfs, northward the Strymonian Gulf and the Gulf of Kavala and the rest are in Turkey; Saros Gulf, Edremit Gulf, Dikili Gulf, Gulf of Çandarlı, Gulf of İzmir, Gulf of Kuşadası, Gulf of Gökova, Güllük Gulf. + +The Aegean sea is connected to the Sea of Marmara by the Dardanelles, also known from Classical Antiquity as the Hellespont. The Dardanelles are located to the northeast of the sea. It ultimately connects with the Black Sea through the Bosphoros strait, upon which lies the city of Istanbul. The Dardanelles and the Bosphoros are known as the Turkish Straits. + +Extent +According to the International Hydrographic Organization, the limits of the Aegean Sea as follows: + + On the south: A line running from Cape Aspro (28°16′E) in Asia Minor, to Cum Burnù (Capo della Sabbia) the Northeast extreme of the Island of Rhodes, through the island to Cape Prasonisi, the Southwest point thereof, on to Vrontos Point (35°33′N) in Skarpanto [Karpathos], through this island to Castello Point, the South extreme thereof, across to Cape Plaka (East extremity of Crete), through Crete to Agria Grabusa, the Northwest extreme thereof, thence to Cape Apolitares in Antikithera Island, through the island to Psira Rock (off the Northwest point) and across to Cape Trakhili in Kithera Island, through Kithera to the Northwest point (Cape Karavugia) and thence to Cape Santa Maria () in the Morea. + In the Dardanelles: A line joining Kum Kale (26°11′E) and Cape Helles. + +Hydrography +Aegean surface water circulates in a counterclockwise gyre, with hypersaline Mediterranean water moving northward along the west coast of Turkey, before being displaced by less dense Black Sea outflow. The dense Mediterranean water sinks below the Black Sea inflow to a depth of , then flows through the Dardanelles Strait and into the Sea of Marmara at velocities of . The Black Sea outflow moves westward along the northern Aegean Sea, then flows southwards along the east coast of Greece. + +The physical oceanography of the Aegean Sea is controlled mainly by the regional climate, the fresh water discharge from major rivers draining southeastern Europe, and the seasonal variations in the Black Sea surface water outflow through the Dardanelles Strait. + +Analysis of the Aegean during 1991 and 1992 revealed three distinct water masses: + + Aegean Sea Surface Water – thick veneer, with summer temperatures of 21–26 °C and winter temperatures ranging from in the north to in the south. + Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from 40 to 50 m to with temperatures ranging from 11 to 18 °C. + Aegean Sea Bottom Water – occurring at depths below 500–1000 m with a very uniform temperature (13–14 °C) and salinity (3.91–3.92%). + +Climate + +The climate of the Aegean Sea largely reflects the climate of Greece and Western Turkey, which is to say, predominantly Mediterranean. According to the Köppen climate classification, most of the Aegean is classified as Hot-summer Mediterranean (Csa), with hotter and drier summers along with milder and wetter winters. However, high temperatures during summers are generally not quite as high as those in arid or semiarid climates due to the presence of a large body of water. This is most predominant in the west and east coasts of the Aegean, and within the Aegean islands. In the north of the Aegean Sea, the climate is instead classified as Cold semi-arid (BSk), which feature cooler summers than Hot-summer Mediterranean climates. The Etesian winds are a dominant weather influence in the Aegean Basin. + +The below table lists climate conditions of some major Aegean cities: + +Population +Numerous Greek and Turkish settlements are located along their mainland coast, as well as on towns on the Aegean islands. The largest cities are Athens and Thessaloniki in Greece and İzmir in Turkey. The most populated of the Aegean islands is Crete, followed by Euboea and Rhodes. + +Biogeography and ecology + +Protected areas +Greece has established several marine protected areas along its coasts. According to the Network of Managers of Marine Protected Areas in the Mediterranean (MedPAN), four Greek MPAs are participating in the Network. These include Alonnisos Marine Park, while the Missolonghi–Aitoliko Lagoons and the island of Zakynthos are not on the Aegean. + +History + +Ancient history + +The current coastline dates back to about 4000 BC. Before that time, at the peak of the last ice age (about 18,000 years ago) sea levels everywhere were 130 metres lower, and there were large well-watered coastal plains instead of much of the northern Aegean. When they were first occupied, the present-day islands including Milos with its important obsidian production were probably still connected to the mainland. The present coastal arrangement appeared around 9,000 years ago, with post-ice age sea levels continuing to rise for another 3,000 years after that. + +The subsequent Bronze Age civilizations of Greece and the Aegean Sea have given rise to the general term Aegean civilization. In ancient times, the sea was the birthplace of two ancient civilizations – the Minoans of Crete and the Myceneans of the Peloponnese. + +The Minoan civilization was a Bronze Age civilization on the island of Crete and other Aegean islands, flourishing from around 3000 to 1450 BC before a period of decline, finally ending at around 1100 BC. It represented the first advanced civilization in Europe, leaving behind massive building complexes, tools, stunning artwork, writing systems, and a massive network of trade. The Minoan period saw extensive trade between Crete, Aegean, and Mediterranean settlements, particularly the Near East. The most notable Minoan palace is that of Knossos, followed by that of Phaistos. The Mycenaean Greeks arose on the mainland, becoming the first advanced civilization in mainland Greece, which lasted from approximately 1600 to 1100 BC. It is believed that the site of Mycenae, which sits close to the Aegean coast, was the center of Mycenaean civilization. The Mycenaeans introduced several innovations in the fields of engineering, architecture and military infrastructure, while trade over vast areas of the Mediterranean, including the Aegean, was essential for the Mycenaean economy. Their syllabic script, the Linear B, offers the first written records of the Greek language and their religion already included several deities that can also be found in the Olympic Pantheon. Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace-centered states that developed rigid hierarchical, political, social and economic systems. At the head of this society was the king, known as wanax. + +The civilization of Mycenaean Greeks perished with the collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the so-called Greek Dark Ages. It is undetermined what cause the collapse of the Mycenaeans. During the Greek Dark Ages, writing in the Linear B script ceased, vital trade links were lost, and towns and villages were abandoned. + +Ancient Greece + +The Archaic period followed the Greek Dark Ages in the 8th century BC. Greece became divided into small self-governing communities, and adopted the Phoenician alphabet, modifying it to create the Greek alphabet. By the 6th century BC several cities had emerged as dominant in Greek affairs: Athens, Sparta, Corinth, and Thebes, of which Athens, Sparta, and Corinth were closest to the Aegean Sea. Each of them had brought the surrounding rural areas and smaller towns under their control, and Athens and Corinth had become major maritime and mercantile powers as well. In the 8th and 7th centuries BC many Greeks emigrated to form colonies in Magna Graecia (Southern Italy and Sicily), Asia Minor and further afield. The Aegean Sea was the setting for one of the most pivotal naval engagements in history, when on September 20, 480 B.C. the Athenian fleet gained a decisive victory over the Persian fleet of the Xerxes II of Persia at the Battle of Salamis. Thus ending any further attempt of western expansion by the Achaemenid Empire. + +The Aegean Sea would later come to be under the control, albeit briefly, of the Kingdom of Macedonia. Philip II and his son Alexander the Great led a series of conquests that led not only to the unification of the Greek mainland and the control of the Aegean Sea under his rule, but also the destruction of the Achaemenid Empire. After Alexander the Great's death, his empire was divided among his generals. Cassander became king of the Hellenistic kingdom of Macedon, which held territory along the western coast of the Aegean, roughly corresponding to modern-day Greece. The Kingdom of Lysimachus had control over the sea's eastern coast. Greece had entered the Hellenistic period. + +Roman rule +The Macedonian Wars were a series of conflicts fought by the Roman Republic and its Greek allies in the eastern Mediterranean against several different major Greek kingdoms. They resulted in Roman control or influence over the eastern Mediterranean basin, including the Aegean, in addition to their hegemony in the western Mediterranean after the Punic Wars. During Roman rule, the land around the Aegean Sea fell under the provinces of Achaea, Macedonia, Thracia, Asia and Creta et Cyrenica (island of Crete) + +Medieval period + +The Fall of the Western Roman Empire allowed its successor state, the Byzantine Empire, to continue Roman control over the Aegean Sea. However, their territory would later be threatened by the Early Muslim conquests initiated by Muhammad in the 7th century. Although the Rashidun Caliphate did not manage to obtain land along the coast of the Aegean sea, its conquest of the Eastern Anatolian peninsula as well as Egypt, the Levant, and North Africa left the Byzantine Empire weakened. The Umayyad Caliphate expanded the territorial gains of the Rashidun Caliphate, conquering much of North Africa, and threatened the Byzantine Empire's control of Western Anatolia, where it meets the Aegean Sea. + +During the 820s, Crete was conquered by a group of Berbers Andalusians exiles led by Abu Hafs Umar al-Iqritishi, and it became an independent Islamic state. The Byzantine Empire launched a campaign that took most of the island back in 842 and 843 under Theoktistos, but the reconquest was not completed and was soon reversed. Later attempts by the Byzantine Empire to recover the island were without success. For the approximately 135 years of its existence, the emirate of Crete was one of the major foes of Byzantium. Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and haven for Muslim corsair fleets that ravaged the Byzantine-controlled shores of the Aegean Sea. Crete returned to Byzantine rule under Nikephoros Phokas, who launched a huge campaign against the Emirate of Crete in 960 to 961. + +Meanwhile, the Bulgarian Empire threatened Byzantine control of Northern Greece and the Aegean coast to the south. Under Presian I and his successor Boris I, the Bulgarian Empire managed to obtain a small portion of the northern Aegean coast. Simeon I of Bulgaria led Bulgaria to its greatest territorial expansion, and managed to conqueror much of the northern and western coasts of the Aegean. The Byzantines later regained control. The Second Bulgarian Empire achieved similar success along, again, the northern and western coasts, under Ivan Asen II of Bulgaria. + +The Seljuq Turks, under the Seljuk Empire, invaded the Byzantine Empire in 1068, from which they annexed almost all the territories of Anatolia, including the east coast of the Aegean Sea, during the reign of Alp Arslan, the second Sultan of the Seljuk Empire. After the death of his successor, Malik Shah I, the empire was divided, and Malik Shah was succeeded in Anatolia by Kilij Arslan I, who founded the Sultanate of Rum. The Byzantines yet again recaptured the eastern coast of the Aegean. + +After Constantinople was occupied by Western European and Venetian forces during the Fourth Crusade, the area around the Aegean sea was fragmented into multiple entities, including the Latin Empire, the Kingdom of Thessalonica, the Empire of Nicaea, the Principality of Achaea, and the Duchy of Athens. The Venetians created the maritime state of the Duchy of the Archipelago, which included all the Cyclades except Mykonos and Tinos. The Empire of Nicaea, a Byzantine rump state, managed to effect the Recapture of Constantinople from the Latins in 1261 and defeat Epirus. Byzantine successes were not to last; the Ottomans would conquer the area around the Aegean coast, but before their expansion the Byzantine Empire had already been weakened from internal conflict. By the late 14th century the Byzantine Empire had lost all control of the coast of the Aegean Sea and could exercise power around their capital, Constantinople. The Ottoman Empire then gained control of all the Aegean coast with the exception of Crete, which was a Venetian colony until 1669. + +Modern Period + +The Greek War of Independence allowed a Greek state on the coast of the Aegean from 1829 onward. The Ottoman Empire held a presence over the sea for over 500 years until its dissolution following World War I, when it was replaced by modern Turkey. During the war, Greece gained control over the area around the northern coast of the Aegean. By the 1930s, Greece and Turkey had about resumed their present-day borders. + +In the Italo-Turkish War of 1912, Italy captured the Dodecanese islands, and had occupied them since, reneging on the 1919 Venizelos–Tittoni agreement to cede them to Greece. The Greco-Italian War took place from October 1940 to April 1941 as part of the Balkans Campaign of World War II. The Italian war aim was to establish a Greek puppet state, which would permit the Italian annexation of the Sporades and the Cyclades islands in the Aegean Sea, to be administered as a part of the Italian Aegean Islands. The German invasion resulted in the Axis occupation of Greece. The German troops evacuated Athens on 12 October 1944, and by the end of the month, they had withdrawn from mainland Greece. Greece was then liberated by Allied troops. + +Economy and politics +Many of the islands in the Aegean have safe harbours and bays. In ancient times, navigation through the sea was easier than travelling across the rough terrain of the Greek mainland, and to some extent, the coastal areas of Anatolia. Many of the islands are volcanic, and marble and iron are mined on other islands. The larger islands have some fertile valleys and plains. + +Of the main islands in the Aegean Sea, two belong to Turkey – Bozcaada (Tenedos) and Gökçeada (Imbros); the rest belong to Greece. Between the two countries, there are political disputes over several aspects of political control over the Aegean space, including the size of territorial waters, air control and the delimitation of economic rights to the continental shelf. These issues are known as the Aegean dispute. + +Transport +Multiple ports are located along the Greek and Turkish coasts of the Aegean Sea. The port of Piraeus in Athens is the chief port in Greece, the largest passenger port in Europe and the third largest in the world, servicing about 20 million passengers annually. With a throughput of 1.4 million TEUs, Piraeus is placed among the top ten ports in container traffic in Europe and the top container port in the Eastern Mediterranean. Piraeus is also the commercial hub of Greek shipping. Piraeus bi-annually acts as the focus for a major shipping convention, known as Posidonia, which attracts maritime industry professionals from all over the world. Piraeus is currently Greece's third-busiest port in terms of tons of goods transported, behind Aghioi Theodoroi and Thessaloniki. The central port serves ferry routes to almost every island in the eastern portion of Greece, the island of Crete, the Cyclades, the Dodecanese, and much of the northern and the eastern Aegean Sea, while the western part of the port is used for cargo services. + +As of 2007, the Port of Thessaloniki was the second-largest container port in Greece after the port of Piraeus, making it one of the busiest ports in Greece. In 2007, the Port of Thessaloniki handled 14,373,245 tonnes of cargo and 222,824 TEU's. Paloukia, on the island of Salamis, is a major passenger port. + +Fishing +Fish are Greece's second-largest agricultural export, and Greece has Europe's largest fishing fleet. Fish captured include sardines, mackerel, grouper, grey mullets, sea bass, and seabream. There is a considerable difference between fish catches between the pelagic and demersal zones; with respect to pelagic fisheries, the catches from the northern, central and southern Aegean area groupings are dominated, respectively, by anchovy, horse mackerels, and boops. For demersal fisheries, the catches from the northern and southern Aegean area groupings are dominated by grey mullets and pickerel (Spicara smaris) respectively. + +The industry has been impacted by the Great Recession. Overfishing and habitat destruction is also a concern, threatening grouper, and seabream populations, resulting in perhaps a 50% decline of fish catch. To address these concerns, Greek fishermen have been offered a compensation by the government. Although some species are defined as protected or threatened under EU legislation, several illegal species such as the molluscs Pinna nobilis, Charonia tritonis and Lithophaga lithophaga, can be bought in restaurants and fish markets around Greece. + +Tourism + +The Aegean islands within the Aegean Sea are significant tourist destinations. Tourism to the Aegean islands contributes a significant portion of tourism in Greece, especially since the second half of the 20th century. A total of five UNESCO World Heritage sites are located the Aegean Islands; these include the Monastery of Saint John the Theologian and the Cave of the Apocalypse on Patmos, the Pythagoreion and Heraion of Samos in Samos, the Nea Moni of Chios, the island of Delos, and the Medieval City of Rhodes. + +Greece is one of the most visited countries in Europe and the world with over 33 million visitors in 2018, and the tourism industry around a quarter of Greece's Gross Domestic Product. The islands of Santorini, Crete, Lesbos, Delos, and Mykonos are common tourist destinations. An estimated 2 million tourists visit Santorini annually. However, concerns relating to overtourism have arisen in recent years, such as issues of inadequate infrastructure and overcrowding. Alongside Greece, Turkey has also been successful in developing resort areas and attracting large number of tourists, contributing to tourism in Turkey. The phrase "Blue Cruise" refers to recreational voyages along the Turkish Riviera, including across the Aegean. The ancient city of Troy, a World Heritage Site, is on the Turkish coast of the Aegean. + +Greece and Turkey both take part in the Blue Flag beach certification programme of the Foundation for Environmental Education. The certification is awarded for beaches and marinas meeting strict quality standards including environmental protection, water quality, safety and services criteria. As of 2015, the Blue Flag has been awarded to 395 beaches and 9 marinas in Greece. Southern Aegean beaches on the Turkish coast include Muğla, with 102 beaches awarded with the blue flag, along with İzmir and Aydın, who have 49 and 30 beaches awarded respectively. + +See also + + Exclusive economic zone of Greece + Geography of Turkey + List of Greek place names + Aegean Boat Report + +References + +External links + + + + +Seas of Greece +Seas of Turkey +Marginal seas of the Mediterranean +European seas +Seas of Asia +Geography of Europe +Geography of West Asia +Landforms of Çanakkale Province +Landforms of Muğla Province +Landforms of İzmir Province +Landforms of Balıkesir Province +Landforms of Edirne Province +Landforms of Aydın Province +A Clockwork Orange is a dystopian satirical black comedy novel by English writer Anthony Burgess, published in 1962. It is set in a near-future society that has a youth subculture of extreme violence. The teenage protagonist, Alex, narrates his violent exploits and his experiences with state authorities intent on reforming him. The book is partially written in a Russian-influenced argot called "Nadsat", which takes its name from the Russian suffix that is equivalent to '-teen' in English. According to Burgess, the novel was a jeu d'esprit written in just three weeks. + +In 2005, A Clockwork Orange was included on Time magazine's list of the 100 best English-language novels written since 1923, and it was named by Modern Library and its readers as one of the 100 best English-language novels of the 20th century. The original manuscript of the book has been kept at McMaster University's William Ready Division of Archives and Research Collections in Hamilton, Ontario, Canada since the institution purchased the documents in 1971. +It is considered one of the most influential dystopian books. + +In 2022, the novel was included on the "Big Jubilee Read" list of 70 books by Commonwealth authors selected to celebrate the Platinum Jubilee of Elizabeth II. + +Plot summary + +Part 1: Alex's world +Alex is a 15-year-old gang leader living in a near-future dystopian city. His friends ("droogs" in the novel's Anglo-Russian slang, "Nadsat") and fellow gang members are Dim, a slow-witted bruiser, who is the gang's muscle; Georgie, an ambitious second-in-command; and Pete, who mostly plays along as the droogs indulge their taste for "ultra-violence" (random, violent mayhem). Characterised as a sociopath and hardened juvenile delinquent, Alex is also intelligent, quick-witted, and enjoys classical music; he is particularly fond of Beethoven, whom he calls "Lovely Ludwig Van". + +The droogs sit in their favourite hangout, the Korova Milk Bar, drinking "milk-plus" (milk laced with the customer's drug of choice) to prepare for a night of ultra-violence. They assault a scholar walking home from the public library; rob a shop, leaving the owner and his wife bloodied and unconscious; beat up a beggar; then scuffle with a rival gang. Joyriding through the countryside in a stolen car, they break into an isolated cottage and terrorise the young couple living there, beating the husband and gang-raping his wife. In a metafictional touch, the husband is a writer working on a manuscript called "A Clockwork Orange", and Alex contemptuously reads out a paragraph that states the novel's main theme before shredding the manuscript. At the Korova, Alex strikes Dim for his crude response to a woman's singing of an operatic passage, and strains within the gang become apparent. At home in his parents' flat, Alex plays classical music at top volume, which he describes as giving him orgasmic bliss before falling asleep. + +Alex feigns illness to his parents to stay out of school the next day. Following an unexpected visit from P.R. Deltoid, his "post-corrective adviser", Alex visits a record store, where he meets two pre-teen girls. He invites them back to the flat, where he drugs and rapes them. That night after a nap, Alex finds his droogs in a mutinous mood, waiting downstairs in the torn-up and graffitied lobby. Georgie challenges Alex for leadership of the gang, demanding that they focus on higher-value targets in their robberies. Alex quells the rebellion by slashing Dim's hand and fighting with Georgie, then soothes the gang by agreeing to Georgie's plan to rob the home of a wealthy elderly woman. Alex breaks in and knocks the woman unconscious, but when he hears sirens and opens the door to flee, Dim strikes him as revenge for the earlier fight. The gang abandons Alex on the front step to be arrested by the police; while in custody, he learns that the woman has died from her injuries. + +Part 2: The Ludovico Technique + +Alex is convicted of murder and sentenced to 14 years in prison. His parents visit one day to inform him that Georgie has been killed in a botched robbery. Two years into his term, he has obtained a job in one of the prison chapels, playing music on the stereo to accompany the Sunday Christian services. The chaplain mistakes Alex's Bible studies for stirrings of faith; in reality, Alex only reads Scripture for the violent or sexual passages. After his fellow cellmates blame him for beating a troublesome cellmate to death, he is chosen to undergo an experimental behaviour modification treatment called the Ludovico Technique in exchange for having the remainder of his sentence commuted. The technique is a form of aversion therapy in which Alex is injected with nausea-inducing drugs while watching graphically violent films, eventually conditioning him to become severely ill at the mere thought of violence. As an unintended consequence, the soundtrack to one of the films, Beethoven's Ninth Symphony, renders Alex unable to enjoy his beloved classical music as before. + +The technique's effectiveness is demonstrated to a group of VIPs, who watch as Alex collapses before a man who slaps him and abases himself before a scantily clad young woman. Although the prison chaplain accuses the state of stripping Alex of free will, the government officials on the scene are pleased with the results, and Alex is released from prison. + +Part 3: After prison +Alex returns to his parents' flat, only to find that they are letting his room to a lodger. Now homeless, he wanders the streets and enters a public library, hoping to learn of a painless method for committing suicide. The old scholar whom Alex had assaulted in Part 1 finds him and beats him with the help of several friends. Two policemen come to Alex's rescue, but they turn out to be Dim and Billyboy, a former rival gang leader. They take Alex outside town, brutalise him, and abandon him there. Alex collapses at the door of an isolated cottage, realising too late that it is the one he and his droogs invaded in Part 1. + +The writer, F. Alexander, still lives here, but his wife has since died of what he believes to be injuries she sustained in the rape. He does not recognise Alex but gives him shelter and questions him about the conditioning he has undergone. Alexander and his colleagues, all highly critical of the government, plan to use Alex as a symbol of state brutality and thus prevent the incumbent government from being re-elected. Alex inadvertently reveals that he was the ringleader of the home invasion; he is removed from the cottage and locked in an upper-storey bedroom as a relentless barrage of classical music plays over speakers. He attempts suicide by leaping from the window. + +Alex wakes up in a hospital, where he is courted by government officials, anxious to counter the bad publicity created by his suicide attempt. He is informed that F. Alexander has been "put away" for Alex's protection and his own. Alex is offered a well-paying job if he agrees to side with the government once discharged. A round of tests reveals that his old violent impulses have returned, indicating that the hospital doctors have undone the effects of his conditioning. As photographers snap pictures, Alex daydreams of orgiastic violence and reflects, "I was cured all right." + +In the final chapter, Alex—now 18 years old and working for the nation's musical recording archives—finds himself halfheartedly preparing for another night of crime with a new gang (Len, Rick, and Bully). After a chance encounter with Pete, who has reformed and married, Alex finds himself taking less and less pleasure in acts of senseless violence. He begins contemplating giving up crime himself to become a productive member of society and start a family of his own while reflecting on the notion that his children could end up being just as destructive as he has been, if not more so. + +Omission of the final chapter in the US +The book has three parts, each with seven chapters. Burgess has stated that the total of 21 chapters was an intentional nod to the age of 21 being recognised as a milestone in human maturation. The 21st chapter was omitted from the editions published in the United States prior to 1986. In the introduction to the updated American text (these newer editions include the missing 21st chapter), Burgess explains that when he first brought the book to an American publisher, he was told that US audiences would never go for the final chapter, in which Alex sees the error of his ways, decides he has lost his taste for violence and resolves to turn his life around. + +At the American publisher's insistence, Burgess allowed their editors to cut the redeeming final chapter from the US version, so that the tale would end on a darker note, with Alex becoming his old, ultraviolent self again – an ending which the publisher insisted would be "more realistic" and appealing to a US audience. The film adaptation, directed by Stanley Kubrick, is based on the American edition of the book, and is considered to be "badly flawed" by Burgess. Kubrick called Chapter 21 "an extra chapter" and claimed that he had not read the original version until he had virtually finished the screenplay and that he had never given serious consideration to using it. In Kubrick's opinion – as in the opinion of other readers, including the original American editor – the final chapter was unconvincing and inconsistent with the book. Kubrick's stance was unusual when compared to the standard Hollywood practice of producing films with the familiar tropes of resolving moral messages and good triumphing over evil before the film's end. + +Characters + Alex: The novel's protagonist and leader among his droogs. He often refers to himself as "Your Humble Narrator". Having coaxed two ten-year-old girls into his bedroom, Alex refers to himself as "Alexander the Large" while raping them; this was later the basis for Alex's claimed surname DeLarge in the 1971 film. + George, Georgie or Georgie Boy: Effectively Alex's greedy second-in-command. Georgie attempts to undermine Alex's status as leader of the gang and take over their gang as the new leader. He is later killed during a botched robbery while Alex is in prison. + Pete: The only one who does not take particular sides when the droogs fight among themselves. He later meets and marries a girl named Georgina, renouncing his violent ways and even losing his former (Nadsat) speech patterns. A chance encounter with Pete in the final chapter influences Alex to realise that he has grown bored with violence and recognise that human energy is better expended on creation than destruction. + Dim: An idiotic and thoroughly gormless member of the gang, persistently condescended to by Alex, but respected to some extent by his droogs for his formidable fighting abilities, his weapon of choice being a length of bike chain. He later becomes a police officer, exacting his revenge on Alex for the abuse he once suffered under his command. + P. R. Deltoid: A criminal rehabilitation social worker assigned the task of keeping Alex on the straight and narrow. He seemingly has no clue about dealing with young people, and is devoid of empathy or understanding for his troublesome charge. Indeed, when Alex is arrested for murdering an old woman and then ferociously beaten by several police officers, Deltoid simply spits on him. + Prison Chaplain: The character who first questions whether it is moral to turn a violent person into a behavioural automaton who can make no choice in such matters. This is the only character who is truly concerned about Alex's welfare; he is not taken seriously by Alex, though. He is nicknamed by Alex "prison charlie" or "chaplin", a pun on Charlie Chaplin. + Billyboy: A rival of Alex's. Early on in the story, Alex and his droogs battle Billyboy and his droogs, which ends abruptly when the police arrive. Later, after Alex is released from prison, Billyboy (along with Dim, who like Billyboy has become a police officer) rescues Alex from a mob, then subsequently beats him in a location out of town. + Prison Governor: The man who decides to let Alex "choose" to be the first reformed by the Ludovico technique. + The Minister of the Interior: The government high-official who determined that the Ludovico's technique will be used to cut recidivism. He is referred to as the Inferior by Alex. + Dr Branom: A scientist, co-developer of the Ludovico technique. He appears friendly and almost paternal towards Alex at first, before forcing him into the theatre and what Alex calls the "chair of torture". + Dr Brodsky: Branom's colleague and co-developer of the Ludovico technique. He seems much more passive than Branom and says considerably less. + F. Alexander: An author who was in the process of typing his magnum opus A Clockwork Orange when Alex and his droogs broke into his house, beat him, tore up his work and then brutally gang-raped his wife, which caused her subsequent death. He is left deeply scarred by these events and when he encounters Alex two years later, he uses him as a guinea pig in a sadistic experiment intended to prove the Ludovico technique unsound. The government imprisons him afterwards. He is given the name Frank Alexander in the film. + Cat Woman: An indirectly named woman who blocks Alex's gang's entrance scheme, and threatens to shoot Alex and set her cats on him if he does not leave. After Alex breaks into her house, she fights with him, ordering her cats to join the melee, but reprimands Alex for fighting them off. She sustains a fatal blow to the head during the scuffle. She is given the name Miss Weathers in the film. + +Analysis + +Background +A Clockwork Orange was written in Hove, then a senescent English seaside town. Burgess had arrived back in Britain after his stint abroad to see that much had changed. A youth culture had developed, based around coffee bars, pop music and teenage gangs. England was gripped by fears over juvenile delinquency. Burgess stated that the novel's inspiration was his first wife Lynne's beating by a gang of drunk American servicemen stationed in England during World War II. She subsequently miscarried. In its investigation of free will, the book's target is ostensibly the concept of behaviourism, pioneered by such figures as B. F. Skinner. + +Burgess later stated that he wrote the book in three weeks. + +Title +Burgess has offered several clarifications about the meaning and origin of its title: + He had overheard the phrase "as queer as a clockwork orange" in a London pub in 1945 and assumed it was a Cockney expression. In Clockwork Marmalade, an essay published in the Listener in 1972, he said that he had heard the phrase several times since that occasion. He also explained the title in response to a question from William Everson on the television programme Camera Three in 1972, "Well, the title has a very different meaning but only to a particular generation of London Cockneys. It's a phrase which I heard many years ago and so fell in love with, I wanted to use it, the title of the book. But the phrase itself I did not make up. The phrase "as queer as a clockwork orange" is good old East London slang and it didn't seem to me necessary to explain it. Now, obviously, I have to give it an extra meaning. I've implied an extra dimension. I've implied the junction of the organic, the lively, the sweet – in other words, life, the orange – and the mechanical, the cold, the disciplined. I've brought them together in this kind of oxymoron, this sour-sweet word." No other record of the expression being used before 1962 has ever appeared, with Kingsley Amis going so far as to note in his Memoirs (1991) that no trace of it appears in Eric Partridge's Dictionary of Historical Slang. However, saying "as queer as ..." followed by an improbable object: "... a clockwork orange", or "... a four-speed walking stick" or "... a left-handed corkscrew" etc. predates Burgess's novel. An early example, "as queer as Dick's hatband", appeared in 1796, and was alluded to in 1757. + His second explanation was that it was a pun on the Malay word orang, meaning "man". The novella contains no other Malay words or links. + In a prefatory note to A Clockwork Orange: A Play with Music, he wrote that the title was a metaphor for "an organic entity, full of juice and sweetness and agreeable odour, being turned into a mechanism". + In his essay Clockwork Oranges, Burgess asserts that "this title would be appropriate for a story about the application of Pavlovian or mechanical laws to an organism which, like a fruit, was capable of colour and sweetness". + While addressing the reader in a letter before some editions of the book, the author says that when a man ceases to have free will, they are no longer a man. "Just a clockwork orange", a shiny, appealing object, but "just a toy to be wound-up by either God or the Devil, or (what is increasingly replacing both) the State." + +This title alludes to the protagonist's negative emotional responses to feelings of evil which prevent the exercise of his free will subsequent to the administration of the Ludovico Technique. To induce this conditioning, Alex is forced to watch scenes of violence on a screen that are systematically paired with negative physical stimulation. The negative physical stimulation takes the form of nausea and "feelings of terror", which are caused by an emetic medicine administered just before the presentation of the films. + +In its original drafts, Burgess used the working title 'The Ludovico Technique,' as he himself described in the foreword in the April 1995 publication. Along with removing the 21st chapter as insisted by his publisher in the original 1962 edition, he would also change the finished product's name to its current title. + +Use of slang + +The book, narrated by Alex, contains many words in a slang argot which Burgess invented for the book, called Nadsat. It is a mix of modified Slavic words, Cockney rhyming slang and derived Russian (like baboochka). For instance, these terms have the following meanings in Nadsat: droog (друг) = friend; moloko (молоко) = milk; gulliver (голова) = head; malchick (мальчик) or malchickiwick = boy; soomka (сумка) = sack or bag; Bog (Бог) = God; horrorshow (хорошо) = good; prestoopnick (преступник) = criminal; rooker (рука) = hand; cal (кал) = crap; veck (человек) = man or guy; litso (лицо) = face; malenky (маленький) = little; and so on. Some words Burgess invented himself or just adapted from pre-existing languages. Compare Polari. + +One of Alex's doctors explains the language to a colleague as "odd bits of old rhyming slang; a bit of gypsy talk, too. But most of the roots are Slav propaganda. Subliminal penetration." Some words are not derived from anything, but merely easy to guess, e.g. "in-out, in-out" or "the old in-out" means sexual intercourse. Cutter, however, means "money", because "cutter" rhymes with "bread-and-butter"; this is rhyming slang, which is intended to be impenetrable to outsiders (especially eavesdropping policemen). Additionally, slang like appypolly loggy ("apology") seems to derive from school boy slang. This reflects Alex's age of 15. + +In the first edition of the book, no key was provided, and the reader was left to interpret the meaning from the context. In his appendix to the restored edition, Burgess explained that the slang would keep the book from seeming dated, and served to muffle "the raw response of pornography" from the acts of violence. + +The term "ultraviolence", referring to excessive or unjustified violence, was coined by Burgess in the book, which includes the phrase "do the ultra-violent". The term's association with aesthetic violence has led to its use in the media. + +Banning and censorship history in the US +In 1976, A Clockwork Orange was removed from an Aurora, Colorado high school because of "objectionable language". A year later in 1977 it was removed from high school classrooms in Westport, Massachusetts over similar concerns with "objectionable" language. In 1982, it was removed from two Anniston, Alabama libraries, later to be reinstated on a restricted basis. Also, in 1973 a bookseller was arrested for selling the novel. The charges were later dropped. However, each of these instances came after the release of Stanley Kubrick's popular 1971 film adaptation of A Clockwork Orange, itself the subject of much controversy. + +Reception + +Initial response +The Sunday Telegraph review was positive, and described the book as "entertaining ... even profound". Kingsley Amis in The Observer acclaimed the novel as "cheerful horror", writing "Mr Burgess has written a fine farrago of outrageousness, one which incidentally suggests a view of juvenile violence I can't remember having met before". Malcolm Bradbury wrote "All of Mr Burgess's powers as a comic writer, which are considerable, have gone into the rich language of his inverted Utopia. If you can stomach the horrors, you'll enjoy the manner". Roald Dahl called it "a terrifying and marvellous book". Many reviewers praised the inventiveness of the language, but expressed unease at the violent subject matter. The Spectator praised Burgess's "extraordinary technical feat" but was uncomfortable with "a certain arbitrariness about the plot which is slightly irritating". New Statesman acclaimed Burgess for addressing "acutely and savagely the tendencies of our time" but called the book "a great strain to read". The Sunday Times review was negative, and described the book as "a very ordinary, brutal and psychologically shallow story". The Times also reviewed the book negatively, describing it as "a somewhat clumsy experiment with science fiction [with] clumsy cliches about juvenile delinquency". The violence was criticised as "unconvincing in detail". + +Writer's appraisal + +Burgess dismissed A Clockwork Orange as "too didactic to be artistic". He said that the violent content of the novel "nauseated" him. + +In 1985, Burgess published Flame into Being: The Life and Work of D. H. Lawrence and while discussing Lady Chatterley's Lover in his biography, Burgess compared the notoriety of D. H. Lawrence's novel with A Clockwork Orange: "We all suffer from the popular desire to make the known notorious. The book I am best known for, or only known for, is a novel I am prepared to repudiate: written a quarter of a century ago, a jeu d'esprit knocked off for money in three weeks, it became known as the raw material for a film which seemed to glorify sex and violence. The film made it easy for readers of the book to misunderstand what it was about, and the misunderstanding will pursue me until I die. I should not have written the book because of this danger of misinterpretation, and the same may be said of Lawrence and Lady Chatterley's Lover." + +Awards and nominations and rankings + 1983 – Prometheus Award (Preliminary Nominee) + 1999 – Prometheus Award (Nomination) + 2002 – Prometheus Award (Nomination) + 2003 – Prometheus Award (Nomination) + 2006 – Prometheus Award (Nomination) + 2008 – Prometheus Award (Hall of Fame Award) + +A Clockwork Orange was chosen by Time magazine as one of the 100 best English-language books from 1923 to 2005. + +Adaptations + +A 1965 film by Andy Warhol entitled Vinyl was an adaptation of Burgess's novel. + +The best known adaptation of the novella is the 1971 film A Clockwork Orange by Stanley Kubrick, featuring Malcolm McDowell as Alex. In 1987, Burgess published a stage play titled A Clockwork Orange: A Play with Music. The play includes songs, written by Burgess, which are inspired by Beethoven and Nadsat slang. + +A manga anthology by Osamu Tezuka entitled Tokeijikake no Ringo (Clockwork Apple) was released in 1983. + +In 1988, a German adaptation of A Clockwork Orange at the intimate theatre of Bad Godesberg featured a musical score by the German punk rock band Die Toten Hosen which, combined with orchestral clips of Beethoven's Ninth Symphony and "other dirty melodies" (so stated by the subtitle), was released on the album Ein kleines bisschen Horrorschau. The track Hier kommt Alex became one of the band's signature songs. + + +In February 1990, another musical version was produced at the Barbican Theatre in London by the Royal Shakespeare Company. Titled A Clockwork Orange: 2004, it received mostly negative reviews, with John Peter of The Sunday Times of London calling it "only an intellectual Rocky Horror Show", and John Gross of The Sunday Telegraph calling it "a clockwork lemon". Even Burgess himself, who wrote the script based on his novel, was disappointed. According to The Evening Standard, he called the score, written by Bono and The Edge of the rock group U2, "neo-wallpaper". Burgess had originally worked alongside the director of the production, Ron Daniels, and envisioned a musical score that was entirely classical. Unhappy with the decision to abandon that score, he heavily criticised the band's experimental mix of hip hop, liturgical, and gothic music. Lise Hand of The Irish Independent reported The Edge as saying that Burgess's original conception was "a score written by a novelist rather than a songwriter". Calling it "meaningless glitz", Jane Edwardes of 20/20 magazine said that watching this production was "like being invited to an expensive French Restaurant – and being served with a Big Mac." + +In 1994, Chicago's Steppenwolf Theater put on a production of A Clockwork Orange directed by Terry Kinney. The American premiere of novelist Anthony Burgess's own adaptation of his A Clockwork Orange starred K. Todd Freeman as Alex. In 2001, UNI Theatre (Mississauga, Ontario) presented the Canadian premiere of the play under the direction of Terry Costa. + +In 2002, Godlight Theatre Company presented the New York Premiere adaptation of A Clockwork Orange at Manhattan Theatre Source. The production went on to play at the SoHo Playhouse (2002), Ensemble Studio Theatre (2004), 59E59 Theaters (2005) and the Edinburgh Festival Fringe (2005). While at Edinburgh, the production received rave reviews from the press while playing to sold-out audiences. The production was directed by Godlight's artistic director, Joe Tantalo. + +In 2003, Los Angeles director Brad Mays and the ARK Theatre Company staged a multi-media adaptation of A Clockwork Orange, which was named "Pick of the Week" by the LA Weekly and nominated for three of the 2004 LA Weekly Theater Awards: Direction, Revival Production (of a 20th-century work), and Leading Female Performance. Vanessa Claire Smith won Best Actress for her gender-bending portrayal of Alex, the music-loving teenage sociopath. This production utilised three separate video streams outputted to seven onstage video monitors – six 19-inch and one 40-inch. In order to preserve the first-person narrative of the book, a pre-recorded video stream of Alex, "your humble narrator", was projected onto the 40-inch monitor, thereby freeing the onstage character during passages which would have been awkward or impossible to sustain in the breaking of the fourth wall. + +An adaptation of the work, based on the original novel, the film and Burgess's own stage version, was performed by the SiLo Theatre in Auckland, New Zealand in early 2007. + +In 2021, the International Anthony Burgess Foundation premiered a webpage cataloging various productions of A Clockwork Orange from around the world. + +Release details + 1962, UK, William Heinemann (ISBN ?), December 1962, Hardcover + 1962, US, W.

It has a population of 921,402 within the city proper, 1,457,018 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the "Venice of the North", for its large number of canals, now designated a UNESCO World Heritage Site. + +Amsterdam was founded at the mouth of the Amstel River that was dammed to control flooding; the city's name derives from a local linguistic variation of the word dam. Originally a small fishing village in the late 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam was the leading centre for finance and trade, as well as a hub of production of secular art. In the 19th and 20th centuries, the city expanded and many new neighborhoods and suburbs were planned and built. The canals of Amsterdam and the 19-20th century Defence Line of Amsterdam are both on the UNESCO World Heritage List. Sloten, annexed in 1921 by the municipality of Amsterdam, is the oldest part of the city, dating to the 9th century. The city has a long tradition of openness, liberalism, and tolerance. Cycling is key to the city's modern character, and there are numerous biking paths and lanes spread throughout the entire city. + +Amsterdam's main attractions include its historic canals; the , the state museum with a vast collection of Dutch Golden Age art; the Van Gogh Museum; the Dam Square, where the Royal Palace of Amsterdam and former city hall () are located; the Amsterdam Museum; Stedelijk Museum, with modern art; Hermitage Amsterdam, the concert hall; the Anne Frank House; the , the Heineken Experience, the ; Hortus Botanicus, NEMO, the red-light district and many cannabis coffee shops. The city is also well known for its nightlife and festival activity; with several of its nightclubs (, Paradiso) among the world's most famous. Primarily known for its artistic heritage, elaborate canal system and narrow canal houses with gabled façades; well-preserved legacies of the city's 17th-century Golden Age, and the establishment of the Van Gogh Museum, displaying the work of the famous Dutch modern artist, have attracted millions of visitors to Amsterdam annually. + +The Amsterdam Stock Exchange, founded in 1602, is considered the oldest "modern" securities market stock exchange in the world. As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered an alpha world city by the Globalization and World Cities Research Network. The city is also the cultural capital of the Netherlands. Many large Dutch institutions have their headquarters in the city, including: the Philips conglomerate, AkzoNobel, Booking.com, TomTom, and ING. Many of the world's largest companies are based in Amsterdam or have established their European headquarters in the city, such as leading technology companies Uber, Netflix and Tesla. In 2022, Amsterdam was ranked the ninth-best city in the world to live in by the Economist Intelligence Unit and 12th globally on quality of living for environment and infrastructure by Mercer. The city was ranked 4th place globally as top tech hub in the Savills Tech Cities 2019 report (2nd in Europe), and 3rd in innovation by Australian innovation agency 2thinknow in their Innovation Cities Index 2009. The Port of Amsterdam is the fifth largest in Europe. The KLM hub and Amsterdam's main airport, Schiphol, is the busiest airport in the Netherlands, the third busiest in Europe, and the 11th busiest airport in the world. The Dutch capital is considered one of the most multicultural cities in the world, with at least 177 nationalities represented. Immigration and ethnic segregation in Amsterdam is a current issue. + +A few of Amsterdam's notable residents throughout its history include painters Rembrandt and Vincent van Gogh, seventeenth-century philosophers Baruch Spinoza, John Locke, René Descartes, and the Holocaust victim and diarist Anne Frank. + +History + +Prehistory +Due to its geographical location in what used to be wet peatland, the founding of Amsterdam is later than other urban centres in the Low Countries. However, around the area of what later became Amsterdam, farmers settled as early as three millennia ago. They lived along the prehistoric IJ river and upstream of its tributary Amstel. The prehistoric IJ was a shallow and quiet stream in peatland behind beach ridges. This secluded area was able to grow into an important local settlement centre, especially in the late Bronze Age, the Iron Age and the Roman Age. Neolithic and Roman artefacts have also been found in the prehistoric Amstel bedding under Amsterdam's Damrak and Rokin, such as shards of Bell Beaker culture pottery (2200-2000 BC) and a granite grinding stone (2700-2750 BC), but the location of these artefacts around the river banks of the Amstel probably point to a presence of a modest semi-permanent or seasonal settlement. Until water issues were controlled, a permanent settlement would not have been possible, since the river mouth and the banks of the Amstel in this period in time were too wet for permanent habitation. + +Founding + +The origins of Amsterdam are linked to the development of a dam on the Amstel River called Amestelle, meaning 'watery area', from Aa(m) 'river' + stelle 'site at a shoreline', 'river bank'. In this area, land reclamation started as early as the late 10th century. Amestelle was located along a side arm of the IJ. This side arm took the name from the eponymous land: Amstel. Amestelle was inhabited by farmers, who lived more inland and more upstream, where the land was not as wet as at the banks of the downstream river mouth. These farmers were starting the reclamation around upstream Ouderkerk aan de Amstel, and later at the other side of the river at Amstelveen. The Van Amstel family, known in documents by this name since 1019, held the stewardship in this northwestern nook of the ecclesiastical district of the bishop of Utrecht. The family later served also under the count of Holland. + +A major turning point in the development of the Amstel river mouth was the All Saint's Flood of 1170. In an extremely short period of time, the shallow river IJ turned into a wide estuary, which from then on offered the Amstel an open connection to the Zuiderzee, IJssel and waterways further afield. This made the water flow of the Amstel more active, so excess water could be drained better. With drier banks, the downstream Amstel mouth became attractive for permanent habitation. Moreover, the river had grown from an insignificant peat stream into a junction of international waterways. A settlement was built here immediately after the landscape change of 1170. Right from the start of its foundation it focused on traffic, production and trade; not on farming, as opposed to how communities had lived further upstream for the past 200 years and northward for thousands of years. The construction of a dam at the mouth of the Amstel, eponymously named Dam, is historically estimated to have occurred between 1264 and 1275. The settlement first appeared in a document from 1275, concerning a road toll granted by the count of Holland Floris V to the residents apud Amestelledamme 'at the dam in the Amstel' or 'at the dam of Amstelland'. This allowed the inhabitants of the village to travel freely through the County of Holland, paying no tolls at bridges, locks and dams. This was a move in a years-long struggle for power in the area between the count of Holland and the Amstel family who governed the area on behalf of the bishop of Utrecht. By 1327, the name had developed into Aemsterdam. + +Middle Ages +The bishop of Utrecht granted Amsterdam zone rights in either 1300 or 1306. Het Mirakel van Amsterdam in 1345, rendered the city an important place of pilgrimage. During the heydays of the Stille Omgang, which became the expression of the pilgrimage after the Protestant Reformation, up to 90,000 pilgrims came to Amsterdam. + +From the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League. From the 15th century on the city established an independent trade route with the Baltic Sea in grain and timber, cutting out the Hanseatic League as middlemen. The city became the staple market of Europe for bulk cargo. This was made possible due to innovations in the herring fishery, from which Amsterdam reaped great wealth. Herring had demand in markets all around Europe. Inventions of on-board gibbing and the haringbuis in 1415, made longer voyages feasible, and hence enabled Dutch fishermen to follow the herring shoals far from the coasts, giving them a monopoly in the industry. + +The herring industry relied on international trade cooperation and large initial investments in ships, which needed many highly skilled and unskilled workers cooperating, which required the import of the necessary raw materials to turn an unfinished product into a marketable one, which required merchants to then sell it throughout the continent and book-keepers and accountants to divide the profit. In short, the herring industry was setting up the foundations for what would later become the transcontinental trade system and the Dutch Golden Age, with Amsterdam at its centre, hence the saying "Amsterdam is built on Herring bones". + +Conflict with Spain + +The Low Countries were part of the Hapsburg inheritance and came under the Spanish monarchy in the early sixteenth century. The Dutch rebelled against Philip II of Spain, who led a defense of Catholicism during the Protestant Reformation. The main reasons for the uprising were the imposition of new taxes, the tenth penny, and the religious persecution of Protestants by the newly introduced Inquisition. The revolt escalated into the Eighty Years' War, which ultimately led to Dutch independence. Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Protestant Huguenots from France, prosperous merchants and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city's intellectual tolerance made Amsterdam a centre for the European free press. + +Centre of the Dutch Golden Age + +During the 17th century, Amsterdam experienced what is considered its Golden Age, during which it became the wealthiest city in the Western world. Ships sailed from Amsterdam to the Baltic Sea, the Caribbean, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network. Amsterdam's merchants had the largest share in both the Dutch East India Company (VOC) and the Dutch West India Company. These companies acquired overseas possessions that later became Dutch colonies. + +Amsterdam was Europe's most important hub for the shipment of goods and was the leading financial centre of the Western world. In 1602, the Amsterdam office of the Dutch East India Company became the world's first stock exchange by trading in its own shares. The Bank of Amsterdam started operations in 1609, acting as a full-service bank for Dutch merchant bankers and as a reserve bank. + +Beginning during this period, Amsterdam also became involved in the trade in African slaves. The city was a major destination port for Dutch slave ships beginning in the 17th century, which lasted until the United Netherlands abolished the Dutch involvement in the trade in 1814 under pressure by the British government. Amsterdam was also a member of the Society of Suriname, an organization founded to oversee the management of Surinam, a Dutch slave colony. On 1 July 2021, the mayor of Amsterdam, Femke Halsema, apologized for the city's involvement in the African slave trade, which had contributed to the city's wealth. + +Decline and modernization +Amsterdam's prosperity declined during the 18th and early 19th centuries. The wars of the Dutch Republic with England (latterly, Great Britain) and France took their toll on the city. During the Napoleonic Wars, Amsterdam's significance reached its lowest point, with Holland being absorbed into the French Empire. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. + +The end of the 19th century is sometimes called Amsterdam's second Golden Age. New museums, a railway station, and the were built; in this same time, the Industrial Revolution reached the city. The Amsterdam–Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. + +20th century–present + +Shortly before the First World War, the city started to expand again, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato rebellion). People started looting stores and warehouses in order to get supplies, mainly food. + +On 1 January 1921, after a flood in 1916, the depleted municipalities of Durgerdam, Holysloot, Zunderdorp and Schellingwoude, all lying north of Amsterdam, were, at their own request, annexed to the city. Between the wars, the city continued to expand, most notably to the west of the Jordaan district in the Frederik Hendrikbuurt and surrounding neighbourhoods. + +Nazi Germany invaded the Netherlands on 10 May 1940 and took control of the country. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to a high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported to Nazi concentration camps, of whom some 60,000 lived in Amsterdam. In response, the Dutch Communist Party organized the February strike attended by 300,000 people to protest against the raids. The most famous deportee was the young Jewish girl Anne Frank, who died in the Bergen-Belsen concentration camp. At the end of the Second World War, communication with the rest of the country broke down, and food and fuel became scarce. Many citizens traveled to the countryside to forage. Dogs, cats, raw sugar beets, and tulip bulbs—cooked to a pulp—were consumed to stay alive. Many trees in Amsterdam were cut down for fuel, and wood was taken from the houses, apartments and other buildings of deported Jews. The city was finally liberated by Canadian forces on 5 May 1945, shortly before the end of the war in Europe. + +Many new suburbs, such as Osdorp, Slotervaart, Slotermeer and Geuzenveld, were built in the years after the Second World War. These suburbs contained many public parks and wide-open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other events of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing, politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings, and also for new roads, as the automobile became available to most people. A metro started operating in 1977 between the new suburb of Bijlmermeer in the city's Zuidoost (southeast) exclave and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect Amsterdam Centraal and the city centre with other parts of the city. + +The required large-scale demolitions began in Amsterdam's former Jewish neighborhood. Smaller streets, such as the Jodenbreestraat and Weesperstraat, were widened and almost all houses and buildings were demolished. At the peak of the demolition, the Nieuwmarktrellen (Nieuwmarkt Riots) broke out; the rioters expressed their fury about the demolition caused by the restructuring of the city. + +As a result, the demolition was stopped and the highway into the city's centre was never fully built; only the metro was completed. Only a few streets remained widened. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organizations, such as Stadsherstel Amsterdam, were founded to restore the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing. The entire city centre has reattained its former splendour and, as a whole, is now a protected area. Many of its buildings have become monuments, and in July 2010 the Grachtengordel (the three concentric canals: Herengracht, Keizersgracht, and Prinsengracht) was added to the UNESCO World Heritage List. + +In the 21st century, the Amsterdam city centre has attracted large numbers of tourists: between 2012 and 2015, the annual number of visitors rose from 10 to 17 million. Real estate prices have surged, and local shops are making way for tourist-oriented ones, making the centre unaffordable for the city's inhabitants. These developments have evoked comparisons with Venice, a city thought to be overwhelmed by the tourist influx. + +Construction of a new metro line connecting the part of the city north of the IJ to its southern part was started in 2003. The project was controversial because its cost had exceeded its budget by a factor of three by 2008, because of fears of damage to buildings in the centre, and because construction had to be halted and restarted multiple times. The new metro line was completed in 2018. + +Since 2014, renewed focus has been given to urban regeneration and renewal, especially in areas directly bordering the city centre, such as Frederik Hendrikbuurt. This urban renewal and expansion of the traditional centre of the city—with the construction on artificial islands of the new eastern IJburg neighbourhood—is part of the Structural Vision Amsterdam 2040 initiative. + +Geography + +Amsterdam is located in the Western Netherlands, in the province of North Holland, the capital of which is not Amsterdam, but rather Haarlem. The river Amstel ends in the city centre and connects to a large number of canals that eventually terminate in the IJ. Amsterdam is about below sea level. The surrounding land is flat as it is formed of large polders. An artificial forest, Amsterdamse Bos, is in the southwest. Amsterdam is connected to the North Sea through the long North Sea Canal. + +Amsterdam is intensely urbanised, as is the Amsterdam metropolitan area surrounding the city. Comprising of land, the city proper has 4,457 inhabitants per km2 and 2,275 houses per km2. Parks and nature reserves make up 12% of Amsterdam's land area. + +Water +Amsterdam has more than of canals, most of which are navigable by boat. The city's three main canals are the Prinsengracht, Herengracht and Keizersgracht. + +In the Middle Ages, Amsterdam was surrounded by a moat, called the Singel, which now forms the innermost ring in the city, and gives the city centre a horseshoe shape. The city is also served by a seaport. It has been compared with Venice, due to its division into about 90 islands, which are linked by more than 1,200 bridges. + +Climate + +Amsterdam has an oceanic climate (Köppen: Cfb) strongly influenced by its proximity to the North Sea to the west, with prevailing westerly winds. + +Amsterdam, as well as most of the North Holland province, lies in USDA Hardiness zone 8b. Frosts mainly occur during spells of easterly or northeasterly winds from the inner European continent. Even then, because Amsterdam is surrounded on three sides by large bodies of water, as well as having a significant heat-island effect, nights rarely fall below , while it could easily be in Hilversum, southeast. + +Summers are moderately warm with a number of hot and humid days with occasional rain every month. The average daily high in August is , and or higher is only measured on average on 2.5 days, placing Amsterdam in AHS Heat Zone 2. The record extremes range from to . +Days with more than of precipitation are common, on average 133 days per year. + +Amsterdam's average annual precipitation is . A large part of this precipitation falls as light rain or brief showers. Cloudy and damp days are common during the cooler months of October through March. + +Demographics + +Historical population + +In 1300, Amsterdam's population was around 1,000 people. While many towns in Holland experienced population decline during the 15th and 16th centuries, Amsterdam's population grew, mainly due to the rise of the profitable Baltic maritime trade especially in grain after the Burgundian victory in the Dutch–Hanseatic War in 1441. The population of Amsterdam was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanized area of the Low Countries. + +This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. Jews from Spain, Portugal and Eastern Europe similarly settled in Amsterdam, as did Germans and Scandinavians. In thirty years, Amsterdam's population more than doubled between 1585 and 1610. By 1600, its population was around 50,000. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilized around 240,000 for most of the 18th century. + +In 1750, Amsterdam was the fourth largest city in Western Europe, behind London (676,000), Paris (560,000) and Naples (324,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than Great Britain, France or the Ottoman Empire. In contrast to those other metropolises, Amsterdam was also surrounded by large towns such as Leiden (about 67,000), Rotterdam (45,000), Haarlem (38,000) and Utrecht (30,000). + +The city's population declined in the early 19th century, dipping under 200,000 in 1820. By the second half of the 19th century, industrialization spurred renewed growth. Amsterdam's population hit an all-time high of 872,000 in 1959, before declining in the following decades due to government-sponsored suburbanisation to so-called groeikernen (growth centres) such as Purmerend and Almere. Between 1970 and 1980, Amsterdam experienced its sharp population decline, peaking at a net loss of 25,000 people in 1973. By 1985 the city had only 675,570 residents. This was soon followed by reurbanization and gentrification, leading to renewed population growth in the 2010s. Also in the 2010s, much of Amsterdam's population growth was due to immigration to the city. + +Immigration + +In the 16th and 17th century, non-Dutch immigrants to Amsterdam were mostly Protestant Huguenots and Flemings, Sephardic Jews, and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War against Catholic Spain. The Westphalians came to Amsterdam mostly for economic reasons; their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty percent of them survived the Holocaust. + +The first mass immigration in the 20th century was by people from Indonesia, who came to Amsterdam after the independence of the Dutch East Indies in the 1940s and 1950s. In the 1960s guest workers from Turkey, Morocco, Italy, and Spain emigrated to Amsterdam. After the independence of Suriname in 1975, a large wave of Surinamese settled in Amsterdam, mostly in the Bijlmer area. Other immigrants, including refugees asylum seekers and undocumented immigrants, came from Europe, the Americas, Asia and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third Land-use planning bill of the Dutch Government. This bill promoted suburbanization and arranged for new developments in so-called "groeikernen", literally cores of growth. Young professionals and artists moved into neighborhoods De Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. Today, people of non-Western origin make up approximately one-fifth of the population of Amsterdam, and more than 30% of the city's children. A slight majority of the residents of Amsterdam have at least one parent who was born outside the country. However, a much larger majority has at least one parent who was born inside the country (intercultural marriages are common in the city). Thus, while the demographics are changing, the city still has an ethnic Dutch majority. Only one in three inhabitants under 15 is an autochthon, or a person who has two parents of Dutch origin. Segregation along ethnic lines is clearly visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighborhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord. + +In 2000, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (8%), most of whose followers were Sunni. In 2015, Christians formed the largest religious group in the city (28% of the population). The next largest religion was Islam (7.1%), most of whose followers were Sunni. + +Religion + +In 1578, the largely Catholic city of Amsterdam joined the revolt against Spanish rule, late in comparison to other major northern Dutch cities. Catholic priests were driven out of the city. Following the Dutch takeover, all churches were converted to Protestant worship. Calvinism was declared the main religion. It was forbidden to openly profess Roman Catholicism and the Catholic hierarchy was prohibited until mid-19th century. This led to the establishment of clandestine churches, covert religious buildings hidden in pre-existing buildings. Catholics, some Jews and dissenting Protestants worshipped in such buildings. A large influx of foreigners of many religions came to 17th-century Amsterdam, in particular Sefardic Jews from Spain and Portugal, Huguenots from France, Lutherans, Mennonites, as well as Protestants from across the Netherlands. This led to the establishment of many non-Dutch-speaking churches. In 1603, the Jewish received permission to practice their religion in the city. In 1639, the first synagogue was consecrated. The Jews came to call the town 'Jerusalem of the West'. + +As they became established in the city, other Christian denominations used converted Catholic chapels to conduct their own services. The oldest English-language church congregation in the world outside the United Kingdom is found at the Begijnhof. Regular services there are still offered in English under the auspices of the Church of Scotland. Being Calvinists, the Huguenots soon integrated into the Dutch Reformed Church, though often retaining their own congregations. Some, commonly referred by the moniker 'Walloon', are recognizable today as they offer occasional services in French. + +In the second half of the 17th century, Amsterdam experienced an influx of Ashkenazim, Jews from Central and Eastern Europe. Jews often fled the pogroms in those areas. The first Ashkenazis who arrived in Amsterdam were refugees from the Khmelnytsky Uprising occurring in Ukraine and the Thirty Years' War, which devastated much of Central Europe. They not only founded their own synagogues, but had a strong influence on the 'Amsterdam dialect' adding a large Yiddish local vocabulary. Despite an absence of an official Jewish ghetto, most Jews preferred to live in the eastern part, which used to be the centre of medieval Amsterdam. The main street of this Jewish neighbourhood was Jodenbreestraat. The neighbourhood comprised the Waterlooplein and the Nieuwmarkt. Buildings in this neighbourhood fell into disrepair after the Second World War a large section of the neighbourhood was demolished during the construction of the metro system. This led to riots, and as a result the original plans for large-scale reconstruction were abandoned by the government. The neighbourhood was rebuilt with smaller-scale residence buildings on the basis of its original layout. + +Catholic churches in Amsterdam have been constructed since the restoration of the episcopal hierarchy in 1853. One of the principal architects behind the city's Catholic churches, Cuypers, was also responsible for the Amsterdam Centraal station and the . + +In 1924, the Catholic Church hosted the International Eucharistic Congress in Amsterdam; numerous Catholic prelates visited the city, where festivities were held in churches and stadiums. Catholic processions on the public streets, however, were still forbidden under law at the time. Only in the 20th century was Amsterdam's relation to Catholicism normalised, but despite its far larger population size, the episcopal see of the city was placed in the provincial town of Haarlem. + +Historically, Amsterdam has been predominantly Christian, in 1900 Christians formed the largest religious group in the city (70% of the population), Dutch Reformed Church formed 45% of the city population, while the Catholic Church formed 25% of the city population. In recent times, religious demographics in Amsterdam have been changed by immigration from former colonies. Hinduism has been introduced from the Hindu diaspora from Suriname and several distinct branches of Islam have been brought from various parts of the world. Islam is now the largest non-Christian religion in Amsterdam. The large community of Ghanaian immigrants have established African churches, often in parking garages in the Bijlmer area. + +Diversity and immigration +Amsterdam experienced an influx of religions and cultures after the Second World War. With 180 different nationalities, Amsterdam is home to one of the widest varieties of nationalities of any city in the world. The proportion of the population of immigrant origin in the city proper is about 50% and 88% of the population are Dutch citizens. + +Amsterdam has been one of the municipalities in the Netherlands which provided immigrants with extensive and free Dutch-language courses, which have benefited many immigrants. + +Inhabitants by origin + +Cityscape and architecture + +Amsterdam fans out south from the Amsterdam Centraal station and Damrak, the main street off the station. The oldest area of the town is known as De Wallen (English: "The Quays"). It lies to the east of Damrak and contains the city's famous red-light district. To the south of De Wallen is the old Jewish quarter of Waterlooplein. + +The medieval and colonial age canals of Amsterdam, known as grachten, embraces the heart of the city where homes have interesting gables. Beyond the Grachtengordel are the former working-class areas of Jordaan and de Pijp. The Museumplein with the city's major museums, the Vondelpark, a 19th-century park named after the Dutch writer Joost van den Vondel, as well as the Plantage neighbourhood, with the zoo, are also located outside the Grachtengordel. + +Several parts of the city and the surrounding urban area are polders. This can be recognised by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer and Watergraafsmeer. + +Canals + +The Amsterdam canal system is the result of conscious city planning. In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam, ruling lords of Amsterdam, whilst gracht means canal, so that the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal) and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and innermost canal, the Singel. + +The canals served for defense, water management and transport. The defenses took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental. + +Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly. The eastern part of the concentric canal plan, covering the area between the Amstel river and the IJ bay, has never been implemented. In the following centuries, the land was used for parks, senior citizens' homes, theatres, other public facilities, and waterways without much planning. Over the years, several canals have been filled in, becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui. + +Expansion + +After the development of Amsterdam's canals in the 17th century, the city did not grow beyond its borders for two centuries. During the 19th century, Samuel Sarphati devised a plan based on the grandeur of Paris and London at that time. The plan envisaged the construction of new houses, public buildings and streets just outside the Grachtengordel. The main aim of the plan, however, was to improve public health. Although the plan did not expand the city, it did produce some of the largest public buildings to date, like the Paleis voor Volksvlijt. + +Following Sarphati, civil engineers Jacobus van Niftrik and Jan Kalff designed an entire ring of 19th-century neighbourhoods surrounding the city's centre, with the city preserving the ownership of all land outside the 17th-century limit, thus firmly controlling development. Most of these neighbourhoods became home to the working class. + +In response to overcrowding, two plans were designed at the beginning of the 20th century which were very different from anything Amsterdam had ever seen before: Plan Zuid (designed by the architect Berlage) and West. These plans involved the development of new neighbourhoods consisting of housing blocks for all social classes. + +After the Second World War, large new neighbourhoods were built in the western, southeastern, and northern parts of the city. These new neighbourhoods were built to relieve the city's shortage of living space and give people affordable houses with modern conveniences. The neighbourhoods consisted mainly of large housing blocks located among green spaces, connected to wide roads, making the neighbourhoods easily accessible by motor car. The western suburbs which were built in that period are collectively called the Westelijke Tuinsteden. The area to the southeast of the city built during the same period is known as the Bijlmer. + +Architecture + +Amsterdam has a rich architectural history. The oldest building in Amsterdam is the Oude Kerk (English: Old Church), at the heart of the Wallen, consecrated in 1306. The oldest wooden building is Het Houten Huys at the Begijnhof. It was constructed around 1425 and is one of only two existing wooden buildings. It is also one of the few examples of Gothic architecture in Amsterdam. The oldest stone building of the Netherlands, The Moriaan is built in 's-Hertogenbosch. + +In the 16th century, wooden buildings were razed and replaced with brick ones. During this period, many buildings were constructed in the architectural style of the Renaissance. Buildings of this period are very recognisable with their stepped gable façades, which is the common Dutch Renaissance style. Amsterdam quickly developed its own Renaissance architecture. These buildings were built according to the principles of the architect Hendrick de Keyser. One of the most striking buildings designed by Hendrick de Keyser is the Westerkerk. In the 17th century baroque architecture became very popular, as it was elsewhere in Europe. This roughly coincided with Amsterdam's Golden Age. The leading architects of this style in Amsterdam were Jacob van Campen, Philips Vingboons and Daniel Stalpaert. + +Philip Vingboons designed splendid merchants' houses throughout the city. A famous building in baroque style in Amsterdam is the Royal Palace on Dam Square. Throughout the 18th century, Amsterdam was heavily influenced by French culture. This is reflected in the architecture of that period. Around 1815, architects broke with the baroque style and started building in different neo-styles. Most Gothic style buildings date from that era and are therefore said to be built in a neo-gothic style. At the end of the 19th century, the Jugendstil or Art Nouveau style became popular and many new buildings were constructed in this architectural style. Since Amsterdam expanded rapidly during this period, new buildings adjacent to the city centre were also built in this style. The houses in the vicinity of the Museum Square in Amsterdam Oud-Zuid are an example of Jugendstil. The last style that was popular in Amsterdam before the modern era was Art Deco. Amsterdam had its own version of the style, which was called the Amsterdamse School. Whole districts were built this style, such as the Rivierenbuurt. A notable feature of the façades of buildings designed in Amsterdamse School is that they are highly decorated and ornate, with oddly shaped windows and doors. + +The old city centre is the focal point of all the architectural styles before the end of the 19th century. Jugendstil and Georgian are mostly found outside the city's centre in the neighbourhoods built in the early 20th century, although there are also some striking examples of these styles in the city centre. Most historic buildings in the city centre and nearby are houses, such as the famous merchants' houses lining the canals. + +Parks and recreational areas + +Amsterdam has many parks, open spaces, and squares throughout the city. The Vondelpark, the largest park in the city, is located in the Oud-Zuid neighbourhood and is named after the 17th-century Amsterdam author Joost van den Vondel. Yearly, the park has around 10 million visitors. In the park is an open-air theatre, a playground and several horeca facilities. In the Zuid borough, is the Beatrixpark, named after Queen Beatrix. Between Amsterdam and Amstelveen is the Amsterdamse Bos ("Amsterdam Forest"), the largest recreational area in Amsterdam. Annually, almost 4.5 million people visit the park, which has a size of 1.000 hectares and is approximately three times the size of Central Park. The Amstelpark in the Zuid borough houses the Rieker windmill, which dates to 1636. Other parks include the Sarphatipark in the De Pijp neighbourhood, the Oosterpark in the Oost borough and the Westerpark in the Westerpark neighbourhood. The city has three beaches: Nemo Beach, Citybeach "Het stenen hoofd" (Silodam) and Blijburg, all located in the Centrum borough. + +The city has many open squares (plein in Dutch). The namesake of the city as the site of the original dam, Dam Square, is the main city square and has the Royal Palace and National Monument. Museumplein hosts various museums, including the , Van Gogh Museum, and Stedelijk Museum. Other squares include Rembrandtplein, Muntplein, Nieuwmarkt, Leidseplein, Spui and Waterlooplein.

Although many small offices remain along the historic canals, centrally based companies have increasingly relocated outside Amsterdam's city centre. Consequently, the Zuidas (English: South Axis) has become the new financial and legal hub of Amsterdam, with the country's five largest law firms and several subsidiaries of large consulting firms, such as Boston Consulting Group and Accenture, as well as the World Trade Centre (Amsterdam) located in the Zuidas district. In addition to the Zuidas, there are three smaller financial districts in Amsterdam: + +around Amsterdam Sloterdijk railway station. Where one can find the offices of several newspapers, such as De Telegraaf. as well as those of Deloitte, the Gemeentelijk Vervoerbedrijf (municipal public transport company), and the Dutch tax offices (Belastingdienst); +around the Johan Cruyff Arena in Amsterdam Zuidoost, with the headquarters of ING Group; +around the Amstel railway station in the Amsterdam-Oost district to the east of the historical city. Amsterdam's tallest building, the Rembrandt Tower, is located here. As are the headquarters of Philips, the Dutch multinational conglomerate. Amsterdam has been a leading city to reduce the use of raw materials and has created a plan to become a circular city by 2050. + +The adjoining municipality of Amstelveen is the location of KPMG International's global headquarters. Other non-Dutch companies have chosen to settle in communities surrounding Amsterdam since they allow freehold property ownership, whereas Amsterdam retains ground rent. + +The Amsterdam Stock Exchange (AEX), now part of Euronext, is the world's oldest stock exchange and, due to Brexit, has overtaken LSE as the largest bourse in Europe. It is near Dam Square in the city centre. + +Port of Amsterdam +The Port of Amsterdam is the fourth-largest port in Europe, the 38th largest port in the world and the second-largest port in the Netherlands by metric tons of cargo. In 2014, the Port of Amsterdam had a cargo throughput of 97,4 million tons of cargo, which was mostly bulk cargo. Amsterdam has the biggest cruise port in the Netherlands with more than 150 cruise ships every year. In 2019, the new lock in IJmuiden opened; since then, the port has been able to grow to 125 million tonnes in capacity. + +Tourism + +Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 5.34 million international visitors annually; this is excluding the 16 million day-trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with four or five stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 85% in 2017, up from 78% in 2006. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city range from 12,000 to 65,000. + +In 2023, the city began running a campaign to dissuade British men between the ages of 18 and 35 from coming to the city as tourists. The ad shows young men being handcuffed by police and is part of a new campaign to clean up the city's reputation. On May 25, 2023, in a bid to crackdown on wild tourist behaviour, the city banned weed smoking in public areas in and around the red light district. + +De Wallen (red-light district) + +De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and best-known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of canals, streets, and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. In recent years, the city government has been closing and repurposing the famous red-light district windows in an effort to clean up the area and reduce the amount of party and sex tourism. + +Retail +Shops in Amsterdam range from large high-end department stores such as founded in 1870 to small speciality shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops. However, as the Negen Straatjes are dominated by fashion stores, the Haarlemmerstraat and Haarlemmerdijk offer a wide variety of stores, just to name some specialities: candy and other food-related stores, lingerie, sneakers, wedding clothing, interior shops, books, Italian deli's, racing and mountain bikes, skatewear, etc. + +The city also features a large number of open-air markets such as the Albert Cuyp Market, Westerstraat-markt, Ten Katemarkt, and Dappermarkt. Some of these markets are held daily, like the Albert Cuypmarkt and the Dappermarkt. Others, like the Westerstraatmarkt, are held every week. + +Fashion + +Several fashion brands and designers are based in Amsterdam. Fashion designers include Iris van Herpen, Mart Visser, Viktor & Rolf, Marlies Dekkers and Frans Molenaar. Fashion models like Yfke Sturm, Doutzen Kroes and Kim Noorda started their careers in Amsterdam. Amsterdam has its garment centre in the World Fashion Center. Fashion photographers Inez van Lamsweerde and Vinoodh Matadin were born in Amsterdam. + +Culture + +During the later part of the 16th century, Amsterdam's Rederijkerskamer (Chamber of rhetoric) organised contests between different Chambers in the reading of poetry and drama. In 1637, Schouwburg, the first theatre in Amsterdam was built, opening on 3 January 1638. The first ballet performances in the Netherlands were given in Schouwburg in 1642 with the Ballet of the Five Senses. In the 18th century, French theatre became popular. While Amsterdam was under the influence of German music in the 19th century there were few national opera productions; the Hollandse Opera of Amsterdam was built in 1888 for the specific purpose of promoting Dutch opera. In the 19th century, popular culture was centred on the Nes area in Amsterdam (mainly vaudeville and music-hall). An improved metronome was invented in 1812 by Dietrich Nikolaus Winkel. The (1885) and Stedelijk Museum (1895) were built and opened. In 1888, the Concertgebouworkest orchestra was established. With the 20th century came cinema, radio and television. Though most studios are located in Hilversum and Aalsmeer, Amsterdam's influence on programming is very strong. Many people who work in the television industry live in Amsterdam. Also, the headquarters of the Dutch SBS Broadcasting Group is located in Amsterdam. + +Museums +The most important museums of Amsterdam are located on the Museumplein (Museum Square), located at the southwestern side of the Rijksmuseum. It was created in the last quarter of the 19th century on the grounds of the former World's fair. The northeastern part of the square is bordered by the large Rijksmuseum. In front of the Rijksmuseum on the square itself is a long, rectangular pond. This is transformed into an ice rink in winter. The northwestern part of the square is bordered by the Van Gogh Museum, House of Bols Cocktail & Genever Experience and Coster Diamonds. The southwestern border of the Museum Square is the Van Baerlestraat, which is a major thoroughfare in this part of Amsterdam. The Concertgebouw is located across this street from the square. To the southeast of the square are several large houses, one of which contains the American consulate. A parking garage can be found underneath the square, as well as a supermarket. The Museumplein is covered almost entirely with a lawn, except for the northeastern part of the square which is covered with gravel. The current appearance of the square was realised in 1999, when the square was remodelled. The square itself is the most prominent site in Amsterdam for festivals and outdoor concerts, especially in the summer. Plans were made in 2008 to remodel the square again because many inhabitants of Amsterdam are not happy with its current appearance. + +The possesses the largest and most important collection of classical Dutch art. +It opened in 1885. Its collection consists of nearly one million objects. The artist most associated with Amsterdam is Rembrandt, whose work, and the work of his pupils, is displayed in the Rijksmuseum. Rembrandt's masterpiece The Night Watch is one of the top pieces of art of the museum. It also houses paintings from artists like Bartholomeus van der Helst, Johannes Vermeer, Frans Hals, Ferdinand Bol, Albert Cuyp, Jacob van Ruisdael and Paulus Potter. Aside from paintings, the collection consists of a large variety of decorative art. This ranges from Delftware to giant doll-houses from the 17th century. The architect of the gothic revival building was P.J.H. Cuypers. The museum underwent a 10-year, 375 million euro renovation starting in 2003. The full collection was reopened to the public on 13 April 2013 and the Rijksmuseum has remained the most visited museum in Amsterdam with 2.2 million visitors in 2016 and 2.16 million in 2017. + +Van Gogh lived in Amsterdam for a short while and there is a museum dedicated to his work. The museum is housed in one of the few modern buildings in this area of Amsterdam. The building was designed by Gerrit Rietveld. This building is where the permanent collection is displayed. A new building was added to the museum in 1999. This building, known as the performance wing, was designed by Japanese architect Kisho Kurokawa. Its purpose is to house temporary exhibitions of the museum. Some of Van Gogh's most famous paintings, like The Potato Eaters and Sunflowers, are in the collection. The Van Gogh museum is the second most visited museum in Amsterdam, not far behind the Rijksmuseum in terms of the number of visits, being approximately 2.1 million in 2016, for example. + +Next to the Van Gogh museum stands the Stedelijk Museum. This is Amsterdam's most important museum of modern art. The museum is as old as the square it borders and was opened in 1895. The permanent collection consists of works of art from artists like Piet Mondrian, Karel Appel, and Kazimir Malevich. After renovations lasting several years, the museum opened in September 2012 with a new composite extension that has been called 'The Bathtub' due to its resemblance to one. + +Amsterdam contains many other museums throughout the city. They range from small museums such as the Verzetsmuseum (Resistance Museum), the Anne Frank House, and the Rembrandt House Museum, to the very large, like the Tropenmuseum (Museum of the Tropics), Amsterdam Museum (formerly known as Amsterdam Historical Museum), Hermitage Amsterdam (a dependency of the Hermitage Museum in Saint Petersburg) and the Joods Historisch Museum (Jewish Historical Museum). The modern-styled Nemo is dedicated to child-friendly science exhibitions. + +Music + +Amsterdam's musical culture includes a large collection of songs that treat the city nostalgically and lovingly. The 1949 song "Aan de Amsterdamse grachten" ("On the canals of Amsterdam") was performed and recorded by many artists, including John Kraaijkamp Sr.; the best-known version is probably that by Wim Sonneveld (1962). In the 1950s Johnny Jordaan rose to fame with "Geef mij maar Amsterdam" ("I prefer Amsterdam"), which praises the city above all others (explicitly Paris); Jordaan sang especially about his own neighbourhood, the Jordaan ("Bij ons in de Jordaan"). Colleagues and contemporaries of Johnny include Tante Leen and Manke Nelis. Another notable Amsterdam song is "Amsterdam" by Jacques Brel (1964). A 2011 poll by Amsterdam newspaper Het Parool that Trio Bier's "Oude Wolf" was voted "Amsterdams lijflied". Notable Amsterdam bands from the modern era include the Osdorp Posse and The Ex. + +AFAS Live (formerly known as the Heineken Music Hall) is a concert hall located near the Johan Cruyff Arena (known as the Amsterdam Arena until 2018). Its main purpose is to serve as a podium for pop concerts for big audiences. Many famous international artists have performed there. Two other notable venues, Paradiso and the are located near the Leidseplein. Both focus on broad programming, ranging from indie rock to hip hop, R&B, and other popular genres. Other more subcultural music venues are OCCII, OT301, De Nieuwe Anita, Winston Kingdom, and Zaal 100. Jazz has a strong following in Amsterdam, with the Bimhuis being the premier venue. In 2012, Ziggo Dome was opened, also near Amsterdam Arena, a state-of-the-art indoor music arena. + +AFAS Live is also host to many electronic dance music festivals, alongside many other venues. Armin van Buuren and Tiesto, some of the worlds leading Trance DJ's hail from the Netherlands and frequently perform in Amsterdam. Each year in October, the city hosts the Amsterdam Dance Event (ADE) which is one of the leading electronic music conferences and one of the biggest club festivals for electronic music in the world, attracting over 350,000 visitors each year. Another popular dance festival is 5daysoff, which takes place in the venues Paradiso and . In the summertime, there are several big outdoor dance parties in or nearby Amsterdam, such as Awakenings, Dance Valley, Mystery Land, Loveland, A Day at the Park, Welcome to the Future, and Valtifest. + +Amsterdam has a world-class symphony orchestra, the Royal Concertgebouw Orchestra. Their home is the , which is across the Van Baerlestraat from the Museum Square. It is considered by critics to be a concert hall with some of the best acoustics in the world. The building contains three halls, Grote Zaal, Kleine Zaal, and Spiegelzaal. Some nine hundred concerts and other events per year take place in the Concertgebouw, for a public of over 700,000, making it one of the most-visited concert halls in the world. The opera house of Amsterdam is located adjacent to the city hall. Therefore, the two buildings combined are often called the Stopera, (a word originally coined by protesters against it very construction: Stop the Opera[-house]). This huge modern complex, opened in 1986, lies in the former Jewish neighbourhood at Waterlooplein next to the river Amstel. The Stopera is the home base of Dutch National Opera, Dutch National Ballet and the Holland Symfonia. Muziekgebouw aan 't IJ is a concert hall, which is located in the IJ near the central station. Its concerts perform mostly modern classical music. Located adjacent to it, is the Bimhuis, a concert hall for improvised and Jazz music. + +Performing arts +Amsterdam has three main theatre buildings. + +The Stadsschouwburg at the Leidseplein is the home base of Toneelgroep Amsterdam. The current building dates from 1894. Most plays are performed in the Grote Zaal (Great Hall). The normal program of events encompasses all sorts of theatrical forms. In 2009, the new hall of the Stadsschouwburg Amsterdam, Toneelgroep Amsterdam and Melkweg opened, and the renovation of the front end of the theatre was ready. + +The Dutch National Opera and Ballet (formerly known as Het Muziektheater), dating from 1986, is the principal opera house and home to Dutch National Opera and Dutch National Ballet. Royal Theatre Carré was built as a permanent circus theatre in 1887 and is currently mainly used for musicals, cabaret performances, and pop concerts. + +The recently re-opened DeLaMar Theater houses more commercial plays and musicals. A new theatre has also moved into the Amsterdam scene in 2014, joining other established venues: Theater Amsterdam is located in the west part of Amsterdam, on the Danzigerkade. It is housed in a modern building with a panoramic view over the harbour. The theatre is the first-ever purpose-built venue to showcase a single play entitled ANNE, the play based on Anne Frank's life. + +On the east side of town, there is a small theatre in a converted bathhouse, the Badhuistheater. The theatre often has English programming. + +The Netherlands has a tradition of cabaret or kleinkunst, which combines music, storytelling, commentary, theatre and comedy. Cabaret dates back to the 1930s and artists like Wim Kan, Wim Sonneveld and Toon Hermans were pioneers of this form of art in the Netherlands. In Amsterdam is the Kleinkunstacademie (English: Cabaret Academy) and Nederlied Kleinkunstkoor (English: Cabaret Choir).

They have their own theatre at Leidseplein. + +Nightlife + +Amsterdam is famous for its vibrant and diverse nightlife. Amsterdam has many cafés (bars). They range from large and modern to small and cosy. The typical Bruine Kroeg (brown café) breathe a more old fashioned atmosphere with dimmed lights, candles, and somewhat older clientele. These brown cafés mostly offer a wide range of local and international artisanal beers. Most cafés have terraces in summertime. A common sight on the Leidseplein during summer is a square full of terraces packed with people drinking beer or wine. Many restaurants can be found in Amsterdam as well. Since Amsterdam is a multicultural city, a lot of different ethnic restaurants can be found. Restaurants range from being rather luxurious and expensive to being ordinary and affordable. Amsterdam also possesses many discothèques. The two main nightlife areas for tourists are the Leidseplein and the Rembrandtplein. The Paradiso, and Sugar Factory are cultural centres, which turn into discothèques on some nights. Examples of discothèques near the Rembrandtplein are the Escape, Air, John Doe and Club Abe. Also noteworthy are Panama, Hotel Arena (East), TrouwAmsterdam and Studio 80. In recent years '24-hour' clubs opened their doors, most notably Radion De School, Shelter and Marktkantine. Bimhuis located near the Central Station, with its rich programming hosting the best in the field is considered one of the best jazz clubs in the world. The Reguliersdwarsstraat is the main street for the LGBT community and nightlife. + +Festivals + +In 2008, there were 140 festivals and events in Amsterdam. During the same year, Amsterdam was designated as the World Book Capital for one year by UNESCO. + +Famous festivals and events in Amsterdam include: Koningsdag (which was named Koninginnedag until the crowning of King Willem-Alexander in 2013) (King's Day – Queen's Day); the Holland Festival for the performing arts; the yearly Prinsengrachtconcert (classical concerto on the Prinsen canal) in August; the 'Stille Omgang' (a silent Roman Catholic evening procession held every March); Amsterdam Gay Pride; The Cannabis Cup; and the Uitmarkt. On Koningsdag—that is held each year on 27 April—hundreds of thousands of people travel to Amsterdam to celebrate with the city's residents. The entire city becomes overcrowded with people buying products from the freemarket, or visiting one of the many music concerts. + +The yearly Holland Festival attracts international artists and visitors from all over Europe. Amsterdam Gay Pride is a yearly local LGBT parade of boats in Amsterdam's canals, held on the first Saturday in August. The annual Uitmarkt is a three-day cultural event at the start of the cultural season in late August. It offers previews of many different artists, such as musicians and poets, who perform on podia. + +Sports + +Amsterdam is home of the Eredivisie football club AFC Ajax. The stadium Johan Cruyff Arena is the home of Ajax. It is located in the south-east of the city next to the new Amsterdam Bijlmer ArenA railway station. Before moving to their current location in 1996, Ajax played their regular matches in the now demolished De Meer Stadion in the eastern part of the city or in the Olympic Stadium. +In 1928, Amsterdam hosted the Summer Olympics. The Olympic Stadium built for the occasion has been completely restored and is now used for cultural and sporting events, such as the Amsterdam Marathon. In 1920, Amsterdam assisted in hosting some of the sailing events for the Summer Olympics held in neighbouring Antwerp, Belgium by hosting events at Buiten IJ. + +The city holds the Dam to Dam Run, a race from Amsterdam to Zaandam, as well as the Amsterdam Marathon. The ice hockey team Amstel Tijgers play in the Jaap Eden ice rink. The team competes in the Dutch ice hockey premier league. Speed skating championships have been held on the 400-meter lane of this ice rink. + +Amsterdam holds two American football franchises: the Amsterdam Crusaders and the Amsterdam Panthers.

Boxer Raymond Joval and field hockey midfielder Carole Thate were the first to receive the awards, in 1999. + +Amsterdam hosted the World Gymnaestrada in 1991 and will do so again in 2023. + +Politics + + +The city of Amsterdam is a municipality under the Dutch Municipalities Act. It is governed by a directly elected municipal council, a municipal executive board and a mayor. Since 1981, the municipality of Amsterdam has gradually been divided into semi-autonomous boroughs, called stadsdelen or 'districts'. Over time, a total of 15 boroughs were created. In May 2010, under a major reform, the number of Amsterdam boroughs was reduced to eight: Amsterdam-Centrum covering the city centre including the canal belt, Amsterdam-Noord consisting of the neighbourhoods north of the IJ lake, Amsterdam-Oost in the east, Amsterdam-Zuid in the south, Amsterdam-West in the west, Amsterdam Nieuw-West in the far west, Amsterdam Zuidoost in the southeast, and Westpoort covering the Port of Amsterdam area. + +City government + +As with all Dutch municipalities, Amsterdam is governed by a directly elected municipal council, a municipal executive board and a government appointed mayor (burgemeester). The mayor is a member of the municipal executive board, but also has individual responsibilities in maintaining public order. On 27 June 2018, Femke Halsema (former member of House of Representatives for GroenLinks from 1998 to 2011) was appointed as the first woman to be Mayor of Amsterdam by the King's Commissioner of North Holland for a six-year term after being nominated by the Amsterdam municipal council and began serving a six-year term on 12 July 2018. She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017. After the 2014 municipal council elections, a governing majority of D66, VVD and SP was formed – the first coalition without the Labour Party since World War II. Next to the Mayor, the municipal executive board consists of eight wethouders ('alderpersons') appointed by the municipal council: four D66 alderpersons, two VVD alderpersons and two SP alderpersons. + +On 18 September 2017, it was announced by Eberhard van der Laan in an open letter to Amsterdam citizens that Kajsa Ollongren would take up his office as acting Mayor of Amsterdam with immediate effect due to ill health. Ollongren was succeeded as acting Mayor by Eric van der Burg on 26 October 2017 and by Jozias van Aartsen on 4 December 2017. + +Unlike most other Dutch municipalities, Amsterdam is subdivided into eight boroughs, called stadsdelen or 'districts', and the urban area of Weesp, a system that was implemented gradually in the 1980s to improve local governance. The boroughs are responsible for many activities that had previously been run by the central city. In 2010, the number of Amsterdam boroughs reached fifteen. Fourteen of those had their own district council (deelraad), elected by a popular vote. The fifteenth, Westpoort, covers the harbour of Amsterdam and had very few residents. Therefore, it was governed by the central municipal council. + +Under the borough system, municipal decisions are made at borough level, except for those affairs pertaining to the whole city such as major infrastructure projects, which are the jurisdiction of the central municipal authorities. In 2010, the borough system was restructured, in which many smaller boroughs merged into larger boroughs. In 2014, under a reform of the Dutch Municipalities Act, the Amsterdam boroughs lost much of their autonomous status, as their district councils were abolished. + +The municipal council of Amsterdam voted to maintain the borough system by replacing the district councils with smaller, but still directly elected district committees (bestuurscommissies). Under a municipal ordinance, the new district committees were granted responsibilities through delegation of regulatory and executive powers by the central municipal council. + +Metropolitan area + +"Amsterdam" is usually understood to refer to the municipality of Amsterdam. Colloquially, some areas within the municipality, such as the town of Durgerdam, may not be considered part of Amsterdam. + +Statistics Netherlands uses three other definitions of Amsterdam: metropolitan agglomeration Amsterdam (Grootstedelijke Agglomeratie Amsterdam, not to be confused with Grootstedelijk Gebied Amsterdam, a synonym of Groot Amsterdam), Greater Amsterdam (Groot Amsterdam, a COROP region) and the urban region Amsterdam (Stadsgewest Amsterdam). The Amsterdam Department for Research and Statistics uses a fourth conurbation, namely the Stadsregio Amsterdam ('City Region of Amsterdam'). The city region is similar to Greater Amsterdam but includes the municipalities of Zaanstad and Wormerland. It excludes Graft-De Rijp. + +The smallest of these areas is the municipality of Amsterdam with a population of about 870,000 in 2021. The larger conurbation had a population of over one million. It includes the municipalities of Zaanstad, Wormerland, Oostzaan, Diemen and Amstelveen only, as well as the municipality of Amsterdam. Greater Amsterdam includes 15 municipalities, and had a population of 1,400,000 in 2021. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Amsterdam Metropolitan Area (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerland, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants. + +Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibilities include regional spatial planning and the metropolitan public transport concessions. + +National capital + +Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam"). Previous versions of the constitution only mentioned "the city of Amsterdam" ("de stad Amsterdam"). For a royal investiture, therefore, the States General of the Netherlands (the Dutch Parliament) meets for a ceremonial joint session in Amsterdam. The ceremony traditionally takes place at the Nieuwe Kerk on Dam Square, immediately after the former monarch has signed the act of abdication at the nearby Royal Palace of Amsterdam. Normally, however, the Parliament sits in The Hague, the city which has historically been the seat of the Dutch government, the Dutch monarchy, and the Dutch supreme court. Foreign embassies are also located in The Hague. + +Symbols + +The coat of arms of Amsterdam is composed of several historical elements. First and centre are three St Andrew's crosses, aligned in a vertical band on the city's shield (although Amsterdam's patron saint was Saint Nicholas). These St Andrew's crosses can also be found on the city shields of neighbours Amstelveen and Ouder-Amstel. This part of the coat of arms is the basis of the flag of Amsterdam, flown by the city government, but also as civil ensign for ships registered in Amsterdam. Second is the Imperial Crown of Austria. In 1489, out of gratitude for services and loans, Maximilian I awarded Amsterdam the right to adorn its coat of arms with the king's crown. Then, in 1508, this was replaced with Maximilian's imperial crown when he was crowned Holy Roman Emperor. In the early years of the 17th century, Maximilian's crown in Amsterdam's coat of arms was again replaced, this time with the crown of Emperor Rudolph II, a crown that became the Imperial Crown of Austria. The lions date from the late 16th century, when city and province became part of the Republic of the Seven United Netherlands. Last came the city's official motto: Heldhaftig, Vastberaden, Barmhartig ("Heroic, Determined, Merciful"), bestowed on the city in 1947 by Queen Wilhelmina, in recognition of the city's bravery during the Second World War. + +Transport + +Metro, tram and bus + +Currently, there are sixteen tram routes and five metro routes. All are operated by municipal public transport operator Gemeentelijk Vervoerbedrijf (GVB), which also runs the city bus network. + +Four fare-free GVB ferries carry pedestrians and cyclists across the IJ lake to the borough of Amsterdam-Noord, and two fare-charging ferries run east and west along the harbour. There are also privately operated water taxis, a water bus, a boat sharing operation, electric rental boats and canal cruises, that transport people along Amsterdam's waterways. + +Regional buses, and some suburban buses, are operated by Connexxion and EBS. International coach services are provided by Eurolines from Amsterdam Amstel railway station, IDBUS from Amsterdam Sloterdijk railway station, and Megabus from the Zuiderzeeweg in the east of the city. + +In order to facilitate easier transport to the centre of Amsterdam, the city has various P+R Locations where people can park their car at an affordable price and transfer to one of the numerous public transport lines. + +Car +Amsterdam was intended in 1932 to be the hub, a kind of Kilometre Zero, of the highway system of the Netherlands, with freeways numbered One to Eight planned to originate from the city. The outbreak of the Second World War and shifting priorities led to the current situation, where only roads A1, A2, and A4 originate from Amsterdam according to the original plan. The A3 to Rotterdam was cancelled in 1970 in order to conserve the Groene Hart. Road A8, leading north to Zaandam and the A10 Ringroad were opened between 1968 and 1974. Besides the A1, A2, A4 and A8, several freeways, such as the A7 and A6, carry traffic mainly bound for Amsterdam. + +The A10 ringroad surrounding the city connects Amsterdam with the Dutch national network of freeways. Interchanges on the A10 allow cars to enter the city by transferring to one of the 18 city roads, numbered S101 through to S118. These city roads are regional roads without grade separation, and sometimes without a central reservation. Most are accessible by cyclists. The S100 Centrumring is a smaller ringroad circumnavigating the city's centre. + +In the city centre, driving a car is discouraged. Parking fees are expensive, and many streets are closed to cars or are one-way. The local government sponsors carsharing and carpooling initiatives such as Autodelen and Meerijden.nu. The local government has also started removing parking spaces in the city, with the goal of removing 10,000 spaces (roughly 1,500 per year) by 2025. + +National rail + +Amsterdam is served by ten stations of the Nederlandse Spoorwegen (Dutch Railways). Five are intercity stops: Sloterdijk, Zuid, Amstel, Bijlmer ArenA and Amsterdam Centraal. The stations for local services are: Lelylaan, RAI, Holendrecht, Muiderpoort and Science Park. Amsterdam Centraal is also an international railway station. From the station there are regular services to destinations such as Austria, Belarus, Belgium, Czech Republic, Denmark, France, Germany, Hungary, Poland, Russia, Switzerland and the United Kingdom. Among these trains are international trains of the Nederlandse Spoorwegen (Amsterdam-Berlin), the Eurostar (Amsterdam-Brussels-London), Thalys (Amsterdam-Brussels-Paris/Lille), and Intercity-Express (Amsterdam–Cologne–Frankfurt). + +Airport + +Amsterdam Airport Schiphol is less than 20 minutes by train from Amsterdam Centraal station and is served by domestic and international intercity trains, such as Thalys, Eurostar and Intercity Brussel. Schiphol is the largest airport in the Netherlands, the third-largest in Europe, and the 14th-largest in the world in terms of passengers. It handles over 68 million passengers per year and is the home base of four airlines, KLM, Transavia, Martinair and Arkefly. , Schiphol was the fifth busiest airport in the world measured by international passenger numbers. This airport is 4 meters below sea level. Although Schiphol is internationally known as Amsterdam Schiphol Airport it actually lies in the neighbouring municipality of Haarlemmermeer, southwest of the city. + +Cycling + +Amsterdam is one of the most bicycle-friendly large cities in the world and is a centre of bicycle culture with good facilities for cyclists such as bike paths and bike racks, and several guarded bike storage garages (fietsenstalling) which can be used. + +According to the most recent figures published by Central Bureau of Statistics (CBS), in 2015 the 442.693 households (850.000 residents) in Amsterdam together owned 847.000 bicycles – 1.91 bicycle per household. Theft is widespreadin 2011, about 83,000 bicycles were stolen in Amsterdam. Bicycles are used by all socio-economic groups because of their convenience, Amsterdam's small size, the of bike paths, the flat terrain, and the inconvenience of driving an automobile. + +Education + +Amsterdam has two universities: the University of Amsterdam (Universiteit van Amsterdam, UvA), and the Vrije Universiteit Amsterdam (VU). Other institutions for higher education include an art school – Gerrit Rietveld Academie, a university of applied sciences – the Hogeschool van Amsterdam, and the Amsterdamse Hogeschool voor de Kunsten. Amsterdam's International Institute of Social History is one of the world's largest documentary and research institutions concerning social history, and especially the history of the labour movement. Amsterdam's Hortus Botanicus, founded in the early 17th century, is one of the oldest botanical gardens in the world, with many old and rare specimens, among them the coffee plant that served as the parent for the entire coffee culture in Central and South America. + +There are over 200 primary schools in Amsterdam. Some of these primary schools base their teachings on particular pedagogic theories like the various Montessori schools. The biggest Montessori high school in Amsterdam is the Montessori Lyceum Amsterdam. Many schools, however, are based on religion. This used to be primarily Roman Catholicism and various Protestant denominations, but with the influx of Muslim immigrants, there has been a rise in the number of Islamic schools. Jewish schools can be found in the southern suburbs of Amsterdam. + +Amsterdam is noted for having five independent grammar schools (Dutch: gymnasia), the Vossius Gymnasium, Barlaeus Gymnasium, St. Ignatius Gymnasium, Het 4e Gymnasium and the Cygnus Gymnasium where a classical curriculum including Latin and classical Greek is taught. Though believed until recently by many to be an anachronistic and elitist concept that would soon die out, the gymnasia have recently experienced a revival, leading to the formation of a fourth and fifth grammar school in which the three aforementioned schools participate. Most secondary schools in Amsterdam offer a variety of different levels of education in the same school. The city also has various colleges ranging from art and design to politics and economics which are mostly also available for students coming from other countries. + +Schools for foreign nationals in Amsterdam include the Amsterdam International Community School, British School of Amsterdam, Albert Einstein International School Amsterdam, Lycée Vincent van Gogh La Haye-Amsterdam primary campus (French school), International School of Amsterdam, and the Japanese School of Amsterdam. + +Notable people + +Media +Amsterdam is a prominent centre for national and international media. Some locally based newspapers include Het Parool, a national daily paper; De Telegraaf, the largest Dutch daily newspaper; the daily newspapers Trouw, de Volkskrant and NRC; De Groene Amsterdammer, a weekly newspaper; the free newspapers Metro and The Holland Times (printed in English). + +Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV-stations SBS 6, Net 5 and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum, south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies. + +In 2012, the music video of Far East Movement, 'Live My Life', was filmed in various parts of Amsterdam. + +Also, several movies were filmed in Amsterdam, such as James Bond's Diamonds Are Forever, Ocean's Twelve, Girl with a Pearl Earring and The Hitman's Bodyguard. Amsterdam is also featured in John Green's book The Fault in Our Stars, which has been made into a film as well that partly takes place in Amsterdam. + +Housing + +From the late 1960s onwards many buildings in Amsterdam have been squatted both for housing and for using as social centres. A number of these squats have legalised and become well known, such as OCCII, OT301, Paradiso and Vrankrijk. + +Sister cities + Manchester, Greater Manchester, United Kingdom, 2007 + Zapopan, Jalisco, Mexico, 2011 + +See also + +List of populated places in the Netherlands +List of cities, towns and villages in North Holland +List of cities in the Netherlands by province +List of national capitals +List of national capitals by latitude +List of capital cities by elevation +List of national capitals by population +van Dam + +References + +Citations + +Literature + +Charles Caspers & Peter Jan Margry (2017), Het Mirakel van Amsterdam.

A subsidiary of the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. + +The origins of the company are complex, dating back to the early 20th century and the initial enterprises (Horch and the Audiwerke) founded by engineer August Horch (1868–1951). Two other manufacturers (DKW and Wanderer) also contributed to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. + +The company name is based on the Latin translation of the surname of the founder, August Horch. , meaning "listen", becomes in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is , which is translated as "Progress through Technology". Audi, along with German brands BMW and Mercedes-Benz, is among the best-selling luxury automobile brands in the world. + +History + +Birth of the company and its name +Automobile company Wanderer was originally established in 1885, later becoming a branch of Audi AG. Another company, NSU, which also later merged into Audi, was founded during this time, and later supplied the chassis for Gottlieb Daimler's four-wheeler. + +On 14 November 1899, August Horch (1868–1951) established the company A. Horch & Cie. in the Ehrenfeld district of Cologne. In 1902, he moved with his company to Reichenbach im Vogtland. On 10 May 1904, he founded the August Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony). + +After troubles with Horch chief financial officer, August Horch left Motorwagenwerke and founded in Zwickau on 16 July 1909, his second company, the August Horch Automobilwerke GmbH. His former partners sued him for trademark infringement. The German Reichsgericht (Supreme Court) in Leipzig, eventually determined that the Horch brand belonged to his former company. + +Since August Horch was prohibited from using "Horch" as a trade name in his new car business, he called a meeting with close business friends, Paul and Franz Fikentscher from Zwickau. At the apartment of Franz Fikentscher, they discussed how to come up with a new name for the company. During this meeting, Franz's son was quietly studying Latin in a corner of the room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars... wouldn't it be a good idea to call it audi instead of horch?" "Horch!" in German means "Hark!" or "hear", which is "Audi" in the singular imperative form of "audire" – "to listen" – in Latin. The idea was enthusiastically accepted by everyone attending the meeting. On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau) was entered in the company's register of Zwickau registration court. + +The first Audi automobile, the Audi Type A 10/ Sport-Phaeton, was produced in the same year, followed by the successor Type B 10/28PS in the same year. + +Audi started with a 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924. + +August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive. Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer when driving on the right. + +The merger of the four companies under the logo of four rings + +In August 1928, Jørgen Rasmussen, the owner of Dampf-Kraft-Wagen (DKW), acquired the majority of shares in Audiwerke AG. In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker, including the manufacturing equipment for 8-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, 6-cylinder and 4-cylinder (the "four" with a Peugeot engine) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork. + +In 1932, Audi merged with Horch, DKW, and Wanderer, to form Auto Union AG, Chemnitz. It was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a power train shared with the Wanderer, but turned 180 degrees, so that the drive shaft faced the front. + +Before World War II, Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. However, this badge was used only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch- or Wanderer-built engines. + +Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of the German car market, while Audi held only 0.1%. After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades. + +Post-World War II + +Like most German manufacturing, at the onset of World War II the Auto Union plants were retooled for military production, and were a target for allied bombing during the war which left them damaged. + +Overrun by the Soviet Army in 1945, on the orders of the Soviet Union military administration the factories were dismantled as part of war reparations. Following this, the company's entire assets were expropriated without compensation. On 17 August 1948, Auto Union AG of Chemnitz was deleted from the commercial register. These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") or AWZ (in English: Automobile Works Zwickau). + +With no prospect of continuing production in Soviet-controlled East Germany, Auto Union executives began the process of relocating what was left of the company to West Germany. A site was chosen in Ingolstadt, Bavaria, to start a spare parts operation in late 1945, which would eventually serve as the headquarters of the reformed Auto Union in 1949. + +The former Audi factory in Zwickau restarted assembly of the pre-war models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to the West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines. The Zwickau plant manufactured the infamous Trabant until 1991, when it came under Volkswagen control—effectively bringing it under the same umbrella as Audi since 1945. + +New Auto Union unit +A new West German headquartered Auto Union was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid. The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines. This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, consisting of an extensive complex of formerly military buildings which was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig. It was only ten years later, after the company had attracted an investor, when funds became available for construction of major car plant at the Ingolstadt head office site. + +In 1958, in response to pressure from Friedrich Flick, then the company's largest single shareholder, Daimler-Benz took an 87% holding in the Auto Union company, and this was increased to a 100% holding in 1959. However, small two-stroke cars were not the focus of Daimler-Benz's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap. + +In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 was fitted with a four-stroke engine and a facelift for the car's front and rear. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi". Later developments of the model were named after their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972. Initially, Volkswagen was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant – to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that Volkswagen had no long-term ambition for the Audi brand, Auto Union engineers under the leadership of Ludwig Kraus developed the first Audi 100 in secret, without Nordhoff's knowledge. When presented with a finished prototype, Nordhoff was so impressed he authorised the car for production, which when launched in 1968, went on to be a huge success. With this, the resurrection of the Audi brand was now complete, this being followed by the first generation Audi 80 in 1972, which would in turn provide a template for VW's new front-wheel-drive water-cooled range which debuted from the mid-1970s onward. + +In 1969, Auto Union merged with NSU, based in Neckarsulm, near Stuttgart. In the 1950s, NSU had been the world's largest manufacturer of motorcycles, but had moved on to produce small cars like the NSU Prinz, the TT and TTS versions of which are still popular as vintage race cars. NSU then focused on new rotary engines based on the ideas of Felix Wankel. In 1967, the new NSU Ro 80 was a car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the "quattro GmbH" (from November 2016 "Audi Sport GmbH"), a subsidiary responsible for development and production of Audi high-performance models: the R8 and the RS model range. + +Modern era + +The new merged company was incorporated on 1 January 1969 and was known as Audi NSU Auto Union AG, with its headquarters at NSU's Neckarsulm plant, and saw the emergence of Audi as a separate brand for the first time since the pre-war era. Volkswagen introduced the Audi brand to the United States for the 1970 model year. That same year, the mid-sized car that NSU had been working on, the K70, originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80, was instead launched as a Volkswagen. + +After the launch of the Audi 100 of 1968, the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) followed in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car. Ultimately, the Audi 80 and 100 (progenitors of the A4 and A6, respectively) became the company's biggest sellers, whilst little investment was made in the fading NSU range; the Prinz models were dropped in 1973 whilst the fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, and by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher-end models. + +The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger was accepted to develop the four-wheel drive technology in Volkswagen's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the "Audi Quattro", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through a centre differential. Commonly referred to as the "Ur-Quattro" (the "Ur-" prefix is a German augmentative used, in this case, to mean "original" and is also applied to the first generation of Audi's S4 and S6 Sport Saloons, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved the viability of all-wheel-drive racecars, and the Audi name became associated with advances in automotive technology. + +In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG. At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH, were formed to own and manage the historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations. + +In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied the low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option.) In 1987, Audi put forward a new and very elegant Audi 90, which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface. + +In the early part of the 21st century, Audi set forth on a German racetrack to claim and maintain several world records, such as top speed endurance. This effort was in-line with the company's heritage from the 1930s racing era Silver Arrows. + +Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW. This began with the release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet. + +By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100, the turbocharged Audi 200 and the Audi V8. There was also a coupé version of the 80/90 with both four- and five-cylinder engines. + +Although the five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine. This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in saloon, coupé and convertible body styles. + +The five-cylinder was soon dropped as a major engine choice; however, a turbocharged version remained. The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro. It was fitted to the Audi Coupé, named the S2, and also to the Audi 100 body, and named the S4. These two models were the beginning of the mass-produced S series of performance cars. + +Audi 5000 unintended acceleration allegations +Sales in the United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power. + +A 60 Minutes report aired 23 November 1986, featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering a problem when the brake pedal was pushed. Subsequent investigation revealed that 60 Minutes had engineered the failure – fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission. + +Audi contended, prior to findings by outside investigators, that the problems were caused by driver error, specifically pedal misapplication. Subsequently, the National Highway Traffic Safety Administration (NHTSA) concluded that the majority of unintended acceleration cases, including all the ones that prompted the 60 Minutes report, were caused by driver error such as confusion of pedals. CBS did not acknowledge the test results of involved government agencies, but did acknowledge the similar results of another study. + +In a review study published in 2012, NHTSA summarized its past findings about the Audi unintended acceleration problems: "Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident." + +This summary is consistent with the conclusions of NHTSA's most technical analysis at the time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver. The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada." + +With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park. A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed. + +Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years, – with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed the affected models – with the 5000 becoming the 100 and 200 in 1989 – and reached the same sales levels again only by model year 2000. + +A 2010 BusinessWeek article – outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls – noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and remains contested in Chicago's Cook County after appeals at the Illinois state and U.S. federal levels. + +Model introductions +In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminium construction. Produced from 1999 to 2005, the Audi A2 was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium space frame, which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement. + +The next major model change came in 1995 when the Audi A4 replaced the Audi 80. The new nomenclature scheme was applied to the Audi 100 to become the Audi A6 (with a minor facelift). This also meant the S4 became the S6 and a new S4 was introduced in the A4 body. The S2 was discontinued. The Audi Cabriolet continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new A3 hatchback model (sharing the Volkswagen Golf Mk4's platform) was introduced to the range in 1996, and the radical Audi TT coupé and roadster were debuted in 1998 based on the same underpinnings. + +The engines available throughout the range were now a 1.4 L, 1.6 L and 1.8 L four-cylinder, 1.8 L four-cylinder turbo, 2.6 L and 2.8 L V6, 2.2 L turbo-charged five-cylinder and the 4.2 L V8 engine. The V6s were replaced by new 2.4 L and 2.8 L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7 L V8 and 6.0 L W12 engine for the A8. + +Audi AG today +Audi's sales grew strongly in the 2000s, with deliveries to customers increasing from 653,000 in 2000 to 1,003,000 in 2008. The largest sales increases came from Eastern Europe (+19.3%), Africa (+17.2%) and the Middle East (+58.5%). China in particular has become a key market, representing 108,000 out of 705,000 cars delivered in the first three quarters of 2009. One factor for its popularity in China is that Audis have become the car of choice for purchase by the Chinese government for officials, and purchases by the government are responsible for 20% of its sales in China. As of late 2009, Audi's operating profit of €1.17 billion ($1.85 billion) made it the biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5 billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses. May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel. In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone. + +Audi manufactures vehicles in seven plants around the world, some of which are shared with other VW Group marques although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants. + +Audi's two principal assembly plants in Germany are: + Ingolstadt, the former Auto Union site originally opened in 1945 and substantially rebuilt by Daimler-Benz in 1962, and acquired by Volkswagen in 1964 (Q2, A3, A4, A5) + Neckarsulm, the former NSU plant, acquired by Volkswagen in 1969: (A4, A5 (cabrio), A6, A7, A8, R8, and all RS variants) - a satellite plant at nearby Böllinger Höfe produces the e-tron GT + +Outside of Germany, Audi produces vehicles at: + Aurangabad, India, since 2006 + Bratislava, Slovakia, shared with Volkswagen, SEAT, Škoda and Porsche (Q7 and Q8) + Brussels, Belgium, acquired from Volkswagen in 2007 (e-tron) + Changchun, China, since 1995 + Győr, Hungary (TT, A3, Q3) + Jakarta, Indonesia, since 2011 + Martorell, Spain, shared with SEAT and Volkswagen (A1, Q3) + San José Chiapa, Mexico (2nd gen Q5) + +In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla, Mexico. This plant became operative in 2016 and produces the second generation Q5. + +From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, which was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand. + +In January 2014, Audi, along with the Wireless Power Consortium, operated a booth which demonstrated a phone compartment using the Qi open interface standard at the Consumer Electronics Show (CES). In May, most of the Audi dealers in the UK falsely claimed that the Audi A7, A8, and R8 were Euro NCAP safety tested, all achieving five out of five stars. In fact none were tested. + +In 2015, Audi admitted that at least 2.1 million Audi cars had been involved in the Volkswagen emissions testing scandal in which software installed in the cars manipulated emissions data to fool regulators and allow the cars to pollute at higher than government-mandated levels. The A1, A3, A4, A5, A6, TT, Q3 and Q5 models were implicated in the scandal. Audi promised to quickly find a technical solution and upgrade the cars so they can function within emissions regulations. Ulrich Hackenberg, the head of research and development at Audi, was suspended in relation to the scandal. Despite widespread media coverage about the scandal through the month of September, Audi reported that U.S. sales for the month had increased by 16.2%. Audi's parent company Volkswagen announced on 18 June 2018 that Audi chief executive Rupert Stadler had been arrested. + +In November 2015, the U.S. Environmental Protection Agency implicated the 3-liter diesel engine versions of the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and the Q5 as further models that had emissions regulation defeat-device software installed. Thus, these models emitted nitrogen oxide at up to nine times the legal limit when the car detected that it was not hooked up to emissions testing equipment. + +In November 2016, Audi expressed an intention to establish an assembly factory in Pakistan, with the company's local partner acquiring land for a plant in Korangi Creek Industrial Park in Karachi. Approval of the plan would lead to an investment of $30 million in the new plant. Audi planned to cut 9,500 jobs in Germany starting from 2020 till 2025 to fund electric vehicles and digital working. + +In February 2020, Volkswagen AG announced that it plans to take over all Audi shares it does not own (totalling 0.36%) via a squeeze-out according to German stock corporation law, thus making Audi a fully owned subsidiary of the Volkswagen Group. This change took effect from 16 November 2020, when Audi became a wholly owned subsidiary of the Volkswagen Group. + +In January 2021, Audi announced that it is planning to sell 1 million vehicles in China in 2023, comparing to 726,000 vehicles in 2020. + +Technology + +Audi AI +Audi AI is a driver assist feature offered by Audi. The company's stated intent is to offer fully autonomous driving at a future time, acknowledging that legal, regulatory and technical hurdles must be overcome to achieve this goal. On 4 June 2017, Audi stated that its new A8 will be fully self-driving for speeds up to 60 km/h using its Audi AI. Contrary to other cars, the driver will not have to do safety checks such as touching the steering wheel every 15 seconds to use this feature. The Audi A8 will therefore be the first production car to reach level 3 autonomous driving, meaning that the driver can safely turn their attention away from driving tasks, e.g. the driver can text or watch a movie. Audi will also be the first manufacturer to use a 3D Lidar system in addition to cameras and ultrasonic sensors for their AI. + +Bodyshells +Audi produces 100% galvanised cars to prevent corrosion, and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975. Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust). + +Space Frame + +Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop. The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs. + +Drivetrains + +Layout +For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution. + +In all its post Volkswagen-era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive). + +Audi has recently applied the quattro badge to models such as the A3 and TT which do not use the Torsen-based system as in prior years with a mechanical center differential, but with the Haldex Traction electro-mechanical clutch AWD system. + +Engines + +Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day. + +In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power. + +For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a "WR12") is created by forming two imaginary narrow-angle 15° VR6 engines at an angle of 72°, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants. The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with . + +Fuel Stratified Injection +New models of the A3, A4, A6 and A8 have been introduced, with the ageing 1.8-litre engine now having been replaced by new Fuel Stratified Injection (FSI) engines. Nearly every petroleum burning model in the range now incorporates this fuel-saving technology. + +Direct-Shift Gearbox +In 2003, Volkswagen introduced the Direct-Shift Gearbox (DSG), a type of dual-clutch transmission. It is a type of automatic transmission, drivable like a conventional torque converter automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electro-hydraulically controlled clutches instead of a torque converter. This is implemented in some VW Golfs, Audi A3, Audi A4 and TT models where DSG is called S-Tronic. + +LED daytime running lights +Beginning in 2005, Audi has implemented white LED technology as daytime running lights (DRL) in their products. The distinctive shape of the DRLs has become a trademark of sorts. LEDs were first introduced on the Audi A8 W12, the world's first production car to have LED DRLs, and have since spread throughout the entire model range. The LEDs are present on some Audi billboards. + +Since 2010, Audi has also offered the LED technology in low- and high-beam headlights. + +Multi Media Interface + +Starting with the 2003 Audi A8, Audi has used a centralised control interface for its on-board infotainment systems, called Multi Media Interface (MMI). It is essentially a rotating control knob and 'segment' buttons – designed to control all in-car entertainment devices (radio, CD changer, iPod, TV tuner), satellite navigation, heating and ventilation, and other car controls with a screen. + +The availability of MMI has gradually filtered down the Audi lineup, and following its introduction on the third generation A3 in 2011, MMI is now available across the entire range. It has been generally well received, as it requires less menu-surfing with its segment buttons around a central knob, along with 'main function' direct access buttons – with shortcuts to the radio or phone functions. The colour screen is mounted on the upright dashboard, and on the A4 (new), A5, A6, A8, and Q7, the controls are mounted horizontally. + +Synthetic fuels + +Audi has assisted with technology to produce synthetic diesel from water and carbon dioxide. Audi calls the synthetic diesel E-diesel. It is also working on synthetic gasoline (which it calls E-gasoline). + +Logistics +Audi uses scanning gloves for parts registration during assembly, and automatic robots to transfer cars from factory to rail cars. + +Models + +Current model range +The following tables list Audi production vehicles that are sold as of 2018: + +S and RS models + +Electric vehicles + +Audi is planning an alliance with the Japanese electronics giant Sanyo to develop a pilot hybrid electric project for the Volkswagen Group. The alliance could result in Sanyo batteries and other electronic components being used in future models of the Volkswagen Group. Concept electric vehicles unveiled to date include the Audi A1 Sportback Concept, Audi A4 TDI Concept E, and the fully electric Audi e-tron Concept Supercar. + +Self-driving cars +In December 2018, Audi announced to invest 14 billion Euro ($15.9 billion) in e-mobility, self-driving cars. + +Production figures + + Data from 1998 to 2010. Figures for different body types/versions of models have been merged to create overall figures for each model. + +Motorsport +Audi has competed in various forms of motorsports. Audi's tradition in motorsport began with their former company Auto Union in the 1930s. In the 1990s, Audi found success in the Touring and Super Touring categories of motor racing after success in circuit racing in North America. + +Rallying + +In 1980, Audi released the Quattro, a four-wheel drive (4WD) turbocharged car that went on to win rallies and races worldwide. It is considered one of the most significant rally cars of all time, because it was one of the first to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. Many critics doubted the viability of four-wheel drive racers, thinking them to be too heavy and complex, yet the Quattro was to become a successful car. It led its first rally before going off the road, however, the rally world had been served notice 4WD was the future. The Quattro went on to achieve much success in the World Rally Championship. It won the 1983 (Hannu Mikkola) and the 1984 (Stig Blomqvist) drivers' titles, and brought Audi the manufacturers' title in 1982 and 1984. + +In 1984, Audi launched the short-wheelbase Sport Quattro which dominated rally races in Monte Carlo and Sweden, with Audi taking all podium places, but succumbed to problems further into WRC contention. In 1985, after another season mired in mediocre finishes, Walter Röhrl finished the season in his Sport Quattro S1, and helped place Audi second in the manufacturers' points. Audi also received rally honours in the Hong Kong to Beijing rally in that same year. Michèle Mouton, the only female driver to win a round of the World Rally Championship and a driver for Audi, took the Sport Quattro S1, now simply called the "S1", and raced in the Pikes Peak International Hill Climb. The climb race pits a driver and car to drive to the summit of the Pikes Peak mountain in Colorado, and in 1985, Michèle Mouton set a new record of 11:25.39, and being the first woman to set a Pikes Peak record. In 1986, Audi formally left international rally racing following an accident in Portugal involving driver Joaquim Santos in his Ford RS200. Santos swerved to avoid hitting spectators in the road, and left the track into the crowd of spectators on the side, killing three and injuring 30. Bobby Unser used an Audi in that same year to claim a new record for the Pikes Peak Hill Climb at 11:09.22. + +In 1987, Walter Röhrl claimed the title for Audi setting a new Pikes Peak International Hill Climb record of 10:47.85 in his Audi S1, which he had retired from the WRC two years earlier. The Audi S1 employed Audi's time-tested inline-five-cylinder turbocharged engine, with the final version generating . The engine was mated to a six-speed gearbox and ran on Audi's famous four-wheel drive system. All of Audi's top drivers drove this car; Hannu Mikkola, Stig Blomqvist, Walter Röhrl and Michèle Mouton. This Audi S1 started the range of Audi 'S' cars, which now represents an increased level of sports-performance equipment within the mainstream Audi model range. + +In the United States +As Audi moved away from rallying and into circuit racing, they chose to move first into America with the Trans-Am in 1988. + +In 1989, Audi moved to International Motor Sports Association (IMSA) GTO with the Audi 90, however as they avoided the two major endurance events (Daytona and Sebring) despite winning on a regular basis, they would lose out on the title. + +Touring cars +In 1990, having completed their objective to market cars in North America, Audi returned to Europe, turning first to the Deutsche Tourenwagen Meisterschaft (DTM) series with the Audi V8, and then in 1993, being unwilling to build cars for the new formula, they turned their attention to the fast-growing Super Touring series, which are a series of national championships. Audi first entered in the French Supertourisme and Italian Superturismo. In the following year, Audi would switch to the German Super Tourenwagen Cup (known as STW), and then to British Touring Car Championship (BTCC) the year after that. + +The Fédération Internationale de l'Automobile (FIA), having difficulty regulating the quattro four-wheel drive system, and the impact it had on the competitors, would eventually ban all four-wheel drive cars from competing in the series in 1998, but by then, Audi switched all their works efforts to sports car racing. + +By 2000, Audi would still compete in the US with their RS4 for the SCCA Speed World GT Challenge, through dealer/team Champion Racing competing against Corvettes, Vipers, and smaller BMWs (where it is one of the few series to permit 4WD cars). In 2003, Champion Racing entered an RS6. Once again, the quattro four-wheel drive was superior, and Champion Audi won the championship. They returned in 2004 to defend their title, but a newcomer, Cadillac with the new Omega Chassis CTS-V, gave them a run for their money. After four victories in a row, the Audis were sanctioned with several negative changes that deeply affected the car's performance. Namely, added ballast weights, and Champion Audi deciding to go with different tyres, and reducing the boost pressure of the turbocharger. + +In 2004, after years of competing with the TT-R in the revitalised DTM series, with privateer team Abt Racing/Christian Abt taking the 2002 title with Laurent Aïello, Audi returned as a full factory effort to touring car racing by entering two factory-supported Joest Racing A4 DTM cars. + +24 Hours of Le Mans + +Audi began racing prototype sportscars in 1999, debuting at the Le Mans 24 hour. Two car concepts were developed and raced in their first season - the Audi R8R (open-cockpit 'roadster' prototype) and the Audi R8C (closed-cockpit 'coupé' GT-prototype). The R8R scored a credible podium on its racing debut at Le Mans and was the concept which Audi continued to develop into the 2000 season due to favourable rules for open-cockpit prototypes. + +However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999. +The factory-supported Joest Racing team won at Le Mans three times in a row with the Audi R8 (2000–2002), as well as winning every race in the American Le Mans Series in its first year. Audi also sold the car to customer teams such as Champion Racing. + +In 2003, two Bentley Speed 8s, with engines designed by Audi, and driven by Joest drivers loaned to the fellow Volkswagen Group company, competed in the GTP class, and finished the race in the top two positions, while the Champion Racing R8 finished third overall, and first in the LMP900 class. Audi returned to the winner's podium at the 2004 race, with the top three finishers all driving R8s: Audi Sport Japan Team Goh finished first, Audi Sport UK Veloqx second, and Champion Racing third. + +At the 2005 24 Hours of Le Mans, Champion Racing entered two R8s, along with an R8 from the Audi PlayStation Team Oreca. The R8s (which were built to old LMP900 regulations) received a narrower air inlet restrictor, reducing power, and an additional of weight compared to the newer LMP1 chassis. On average, the R8s were about 2–3 seconds off pace compared to the Pescarolo–Judd. But with a team of excellent drivers and experience, both Champion R8s were able to take first and third, while the Oreca team took fourth. The Champion team was also the first American team to win Le Mans since the Gulf Ford GTs in 1967. This also ends the long era of the R8; however, its replacement for 2006, called the Audi R10 TDI, was unveiled on 13 December 2005. + +The R10 TDI employed many new and innovative features, the most notable being the twin-turbocharged direct injection diesel engine. It was first raced in the 2006 12 Hours of Sebring as a race-test in preparation for the 2006 24 Hours of Le Mans, which it later went on to win. Audi had a win in the first diesel sports car at 12 Hours of Sebring (the car was developed with a Diesel engine due to ACO regulations that favor diesel engines). As well as winning the 24 Hours of Le Mans in 2006, the R10 TDI beat the Peugeot 908 HDi FAP in , and in , (however Peugeot won the 24h in 2009) with a podium clean-sweep (all four 908 entries retired) while breaking a distance record (set by the Porsche 917K of Martini Racing in ), in with the R15 TDI Plus. + +Audi's sports car racing success would continue with the Audi R18's victory at the 2011 24 Hours of Le Mans. Audi Sport Team Joest's Benoît Tréluyer earned Audi their first pole position in five years while the team's sister car locked out the front row. Early accidents eliminated two of Audi's three entries, but the sole remaining Audi R18 TDI of Tréluyer, Marcel Fässler, and André Lotterer held off the trio of Peugeot 908s to claim victory by a margin of 13.8 seconds. + +Results + +American Le Mans Series +Audi entered a factory racing team run by Joest Racing into the American Le Mans Series under the Audi Sport North America name in 2000. This was a successful operation with the team winning on its debut in the series at the 2000 12 Hours of Sebring. Factory-backed Audi R8s were the dominant car in ALMS taking 25 victories between 2000 and the end of the 2002 season. In 2003, Audi sold customer cars to Champion Racing as well as continuing to race the factory Audi Sport North America team. Champion Racing won many races as a private team running Audi R8s and eventually replaced Team Joest as the Audi Sport North America between 2006 and 2008. Since 2009 Audi has not taken part in full American Le Mans Series Championships, but has competed in the series opening races at Sebring, using the 12-hour race as a test for Le Mans, and also as part of the 2012 FIA World Endurance Championship season calendar. + +Results + +European Le Mans Series +Audi participated in the 2003 1000km of Le Mans which was a one-off sports car race in preparation for the 2004 European Le Mans Series. The factory team Audi Sport UK won races and the championship in the 2004 season but Audi was unable to match their sweeping success of Audi Sport North America in the American Le Mans Series, partly due to the arrival of a factory competitor in LMP1, Peugeot. The French manufacturer's 908 HDi FAP became the car to beat in the series from 2008 onwards with 20 LMP wins. However, Audi were able to secure the championship in 2008 even though Peugeot scored more race victories in the season. + +Results + +World Endurance Championship + +2012 +In 2012, the FIA sanctioned a World Endurance Championship which would be organised by the ACO as a continuation of the ILMC. Audi competed won the first WEC race at Sebring and followed this up with a further three successive wins, including the 2012 24 Hours of Le Mans. Audi scored a final 5th victory in the 2012 WEC in Bahrain and were able to win the inaugural WEC Manufacturers' Championship. + +2013 +As defending champions, Audi once again entered the Audi R18 e-tron quattro chassis into the 2013 WEC and the team won the first five consecutive races, including the 2013 24 Hours of Le Mans. The victory at Round 5, Circuit of the Americas, was of particular significance as it marked the 100th win for Audi in Le Mans prototypes. Audi secured their second consecutive WEC Manufacturers' Championship at Round 6 after taking second place and half points in the red-flagged Fuji race. + +2014 +For the 2014 season, Audi entered a redesigned and upgraded R18 e-tron quattro which featured a 2 MJ energy recovery system. As defending champions, Audi would once again face a challenge in LMP1 from Toyota, and additionally from Porsche who returned to endurance racing after a 16-year absence. The season-opening 6hrs of Silverstone was a disaster for Audi who saw both cars retire from the race, marking the first time that an Audi car has failed to score a podium in a World Endurance Championship race. + +Results + +Formula E +Audi provide factory support to Abt Sportsline in the FIA Formula E Championship, The team competed under the title of Audi Sport Abt Formula E Team in the inaugural 2014-15 Formula E season. On 13 February 2014 the team announced its driver line up as Daniel Abt and World Endurance Championship driver Lucas di Grassi. + +Formula One +Audi has been linked to Formula One in recent years but has always resisted due to the company's opinion that it is not relevant to road cars, but hybrid power unit technology has been adopted into the sport, swaying the company's view and encouraging research into the program by former Ferrari team principal Stefano Domenicali. + +Audi announced in August 2022 that it would enter the Championship as an engine manufacturer in . In October, Audi confirmed its partnership with Sauber Motorsport for the year 2026, acquiring a stake in the company for the German brand to enter the competition by renaming the team and supplying engines. + +Current factory drivers + +Marketing + +Branding + +The Audi emblem is four overlapping rings that represent the four marques of Auto Union. The Audi emblem symbolises the amalgamation of Audi with DKW, Horch and Wanderer: the first ring from the left represents Audi, the second represents DKW, third is Horch, and the fourth and last ring Wanderer. +The design is popularly believed to have been the idea of Klaus von Oertzen, the director of sales at Wanderer – when Berlin was chosen as the host city for the 1936 Summer Olympics and that a form of the Olympic logo symbolized the newly established Auto Union's desire to succeed. Somewhat ironically, the International Olympic Committee later sued Audi in the International Trademark Court in 1995, where they lost. + +The original "Audi" script, with the distinctive slanted tails on the "A" and "d" was created for the historic Audi company in 1920 by the famous graphic designer Lucian Bernhard, and was resurrected when Volkswagen revived the brand in 1965. Following the demise of NSU in 1977, less prominence was given to the four rings, in preference to the "Audi" script encased within a black (later red) ellipse, and was commonly displayed next to the Volkswagen roundel when the two brands shared a dealer network under the V.A.G banner. The ellipse (known as the Audi Oval) was phased out after 1994, when Audi formed its own independent dealer network, and prominence was given back to the four rings – at the same time Audi Sans (a derivative of Univers) was adopted as the font for all marketing materials, corporate communications and was also used in the vehicles themselves. + +As part of Audi's centennial celebration in 2009, the company updated the logo, changing the font to left-aligned Audi Type, and altering the shading for the overlapping rings. The revised logo was designed by Rayan Abdullah. + +Audi developed a Corporate Sound concept, with Audi Sound Studio designed for producing the Corporate Sound. The Corporate Sound project began with sound agency Klangerfinder GmbH & Co KG and s12 GmbH. Audio samples were created in Klangerfinder's sound studio in Stuttgart, becoming part of Audi Sound Studio collection. Other Audi Sound Studio components include The Brand Music Pool, The Brand Voice. Audi also developed Sound Branding Toolkit including certain instruments, sound themes, rhythm and car sounds which all are supposed to reflect the AUDI sound character. + +Audi started using a beating heart sound trademark beginning in 1996. An updated heartbeat sound logo, developed by agencies KLANGERFINDER GmbH & Co KG of Stuttgart and S12 GmbH of Munich, was first used in 2010 in an Audi A8 commercial with the slogan The Art of Progress. + +Slogans +Audi's corporate tagline is , meaning "Progress through Technology". The German-language tagline is used in many European countries, including the United Kingdom (but not in Italy, where is used), and in other markets, such as Latin America, Oceania, Africa and parts of Asia including Japan. Originally, the American tagline was Innovation through technology, but in Canada Vorsprung durch Technik was used. Since 2007, Audi has used the slogan Truth in Engineering in the U.S. However, since the Audi emissions testing scandal came to light in September 2015, this slogan was lambasted for being discordant with reality. In fact, just hours after disgraced Volkswagen CEO Martin Winterkorn admitted to cheating on emissions data, an advertisement during the 2015 Primetime Emmy Awards promoted Audi's latest advances in low emissions technology with Kermit the Frog stating, "It's not that easy being green." + +Vorsprung durch Technik was first used in English-language advertising after Sir John Hegarty of the Bartle Bogle Hegarty advertising agency visited the Audi factory in 1982. In the original British television commercials, the phrase was voiced by Geoffrey Palmer. After its repeated use in advertising campaigns, the phrase found its way into popular culture, including the British comedy Only Fools and Horses, the U2 song "Zooropa" and the Blur song "Parklife". Similar-sounding phrases have also been used, including as the punchline for a joke in the movie Lock, Stock and Two Smoking Barrels and in the British TV series Peep Show. + +Typography +Audi Sans (based on Univers Extended) was originally created in 1997 by Ole Schäfer for MetaDesign. MetaDesign was later commissioned for a new corporate typeface called Audi Type, designed by Paul van der Laan and Pieter van Rosmalen of Bold Monday. The font began to appear in Audi's 2009 products and marketing materials. + +Sponsorships + +Audi is a strong partner of different kinds of sports. In football, long partnerships exist between Audi and domestic clubs including Bayern Munich, Hamburger SV, 1. FC Nürnberg, Hertha BSC, and Borussia Mönchengladbach and international clubs including Chelsea, Real Madrid, FC Barcelona, A.C. Milan, AFC Ajax and Perspolis. Audi also sponsors winter sports: The Audi FIS Alpine Ski World Cup is named after the company. Additionally, Audi supports the German Ski Association (DSV) as well as the alpine skiing national teams of Switzerland, Sweden, Finland, France, Liechtenstein, Italy, Austria and the U.S. For almost two decades, Audi fosters golf sport: for example with the Audi quattro Cup and the HypoVereinsbank Ladies German Open presented by Audi. In sailing, Audi is engaged in the Medcup regatta and supports the team Luna Rossa during the Louis Vuitton Pacific Series and also is the primary sponsor of the Melges 20 sailboat. Further, Audi sponsors the regional teams ERC Ingolstadt (hockey) and FC Ingolstadt 04 (soccer). In 2009, the year of Audi's 100th anniversary, the company organized the Audi Cup for the first time. Audi also sponsor the New York Yankees as well. In October 2010 they agreed to a three sponsorship year-deal with Everton. Audi also sponsors the England Polo Team and holds the Audi Polo Awards. + +Marvel Cinematic Universe +Since the start of the Marvel Cinematic Universe, Audi signed a deal to sponsor, promote and provide vehicles for several films. So far these have been, Iron Man, Iron Man 2, Iron Man 3, Avengers: Age of Ultron, Captain America: Civil War, Spider-Man: Homecoming, Avengers: Endgame and Spider-Man: Far From Home. The R8 supercar became the personal vehicle for Tony Stark (played by Robert Downey Jr.) for six of these films. The e-tron vehicles were promoted in Endgame and Far From Home. Several commercials were co-produced by Marvel and Audi to promote several new concepts and some of the latest vehicles such as the A8, SQ7 and the e-Tron fleet. + +Multitronic campaign + +In 2001, Audi promoted the new multitronic continuously variable transmission with television commercials throughout Europe, featuring an impersonator of musician and actor Elvis Presley. A prototypical dashboard figure – later named "Wackel-Elvis" ("Wobble Elvis" or "Wobbly Elvis") – appeared in the commercials to demonstrate the smooth ride in an Audi equipped with the multitronic transmission. The dashboard figure was originally intended for use in the commercials only, but after they aired the demand for Wackel-Elvis fans grew among fans and the figure was mass-produced in China and marketed by Audi in their factory outlet store. + +Audi TDI +As part of Audi's attempt to promote its Diesel technology in 2009, the company began Audi Mileage Marathon. The driving tour featured a fleet of 23 Audi TDI vehicles from 4 models (Audi Q7 3.0 TDI, Audi Q5 3.0 TDI, Audi A4 3.0 TDI, Audi A3 Sportback 2.0 TDI with S tronic transmission) travelling across the American continent from New York to Los Angeles, passing major cities like Chicago, Dallas and Las Vegas during the 13 daily stages, as well as natural wonders including the Rocky Mountains, Death Valley and the Grand Canyon. + +Audi e-tron +The next phase of technology Audi is developing is the e-tron electric drive powertrain system. They have shown several concept cars , each with different levels of size and performance. The original e-tron concept shown at the 2009 Frankfurt motor show is based on the platform of the R8 and has been scheduled for limited production. Power is provided by electric motors at all four wheels. The second concept was shown at the 2010 Detroit Motor Show. Power is provided by two electric motors at the rear axle. This concept is also considered to be the direction for a future mid-engined gas-powered 2-seat performance coupe. The Audi A1 e-tron concept, based on the Audi A1 production model, is a hybrid vehicle with a range extending Wankel rotary engine to provide power after the initial charge of the battery is depleted. It is the only concept of the three to have range-extending capability. The car is powered through the front wheels, always using electric power. + +It is all set to be displayed at the Auto Expo 2012 in New Delhi, India, from 5 January. Powered by a 1.4 litre engine, and can cover a distance up to 54 km s on a single charge. The e-tron was also shown in the 2013 blockbuster film Iron Man 3 and was driven by Tony Stark (Iron Man). + +Lawsuit on the use of the letter Q +In early 2005, Nissan North America Inc. filed a lawsuit against Audi over the use of the letter "Q" as a model name. + +Audi is using the "Q" for the designation of their quattro four-wheel drive system, used in production cars for over twenty-five years (Audi's Quattro trademark is actually an umbrella term for several types of four-wheel-drive systems developed by Torsen, Haldex Traction AB, and Borg-Warner, the latter being used in the Q7). Nissan's Infiniti marque first used Q for their 1989 Infiniti Q45 flagship, but later expanded to its entire lineup, with Q for passenger cars (the Q30, Q40, Q50, and Q60) and QX for SUVs (the QX30, QX50, QX60, and QX70). + +A settlement between Audi AG and Nissan was reached in late 2006. The agreement stipulates that Audi will only use the Q-prefix for three models, the Q3, Q5 and the Q7. Audi has since released other Q series cars as well, such as the Q2, Q6, and Q8. + +In video games +Audi has supported the European version of PlayStation Home, the PlayStation 3's online community-based service, by releasing a dedicated Home space. Audi is the first carmaker to develop such a space for Home. On 17 December 2009, Audi released two spaces; the Audi Home Terminal and the Audi Vertical Run. The Audi Home Terminal features an Audi TV channel delivering video content, an Internet Browser feature, and a view of a city. The Audi Vertical Run is where users can access the mini-game Vertical Run, a futuristic mini-game featuring Audi's e-tron concept. Players collect energy and race for the highest possible speeds and the fastest players earn a place in the Audi apartments located in a large tower in the centre of the Audi Space. In both the Home Terminal and Vertical Run spaces, there are teleports where users can teleport back and forth between the two spaces. Audi had stated that additional content would be added in 2010. On 31 March 2015 Sony shutdown the PlayStation Home service rendering all content for it inaccessible. + +See also + DKW + Horch + Wanderer (company) + +Notes + +References + +External links + + + + +Car brands +Car manufacturers of Germany +Companies based in Baden-Württemberg +Companies based in Bavaria +Companies based in Ingolstadt +Companies formerly listed on the Frankfurt Stock Exchange +Vehicle manufacturing companies established in 1909 +Vehicle manufacturing companies disestablished in 1939 +Vehicle manufacturing companies established in 1965 +Re-established companies +German brands +Luxury motor vehicle manufacturers +Companies based in Saxony +Sports car manufacturers +Volkswagen Group +German companies established in 1909 +An aircraft (: aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. + +The human activity that surrounds aircraft is called aviation. The science of aviation, including designing and building aircraft, is called aeronautics. Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion (if any), usage and others. + +History + +Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air balloons developed in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras: + Pioneers of flight, from the earliest experiments to 1914. + First World War, 1914 to 1918. + Aviation between the World Wars, 1918 to 1939. + Second World War, 1939 to 1945. + Postwar era, also called the Jet Age, 1945 to the present day. + +Methods of lift + +Lighter than air – aerostats + +Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large cells or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, it adds up to the same weight as the air that the craft displaces. + +Small hot-air balloons, called sky lanterns, were first invented in ancient China prior to the 3rd century BC and used primarily in cultural celebrations, and were only the second type of aircraft to fly, the first being kites, which were first invented in ancient China over two thousand years ago (see Han Dynasty). + +A balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs — usually fixed-wing. In 1919, Frederick Handley Page was reported as referring to "ships of the air," with smaller passenger types as "Air yachts." In the 1930s, large intercontinental flying boats were also sometimes referred to as "ships of the air" or "flying-ships". — though none had yet been built. The advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by a rigid outer framework and separate aerodynamic skin surrounding the gas bags, were produced, the Zeppelins being the largest and most famous. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, so "airship" came to be synonymous with these aircraft. Then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a "balloon" is an unpowered aerostat and an "airship" is a powered one. + +A powered, steerable aerostat is called a dirigible. Sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps. During World War II, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon. The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered. + +Heavier-than-air – aerodynes + +Heavier-than-air aircraft, such as airplanes, must find some way to push air or gas downwards so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term. There are two ways to produce dynamic upthrust — aerodynamic lift, and powered lift in the form of engine thrust. + +Aerodynamic lift involving wings is the most common, with fixed-wing aircraft being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called "rotary wings." A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, air must flow over the wing and generate lift. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed, or rotary. + +With powered lift, the aircraft directs its engine thrust vertically downward. V/STOL aircraft, such as the Harrier jump jet and Lockheed Martin F-35B take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. + +A pure rocket is not usually regarded as an aerodyne because it does not depend on the air for its lift (and can even fly into space); however, many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles that obtain aerodynamic lift at very high speed due to airflow over their bodies are a marginal case. + +Fixed-wing + +The forerunner of the fixed-wing aircraft is the kite. Whereas a fixed-wing aircraft relies on its forward speed to create airflow over the wings, a kite is tethered to the ground and relies on the wind blowing over its wings to provide lift. Kites were the first kind of aircraft to fly and were invented in China around 500 BC. Much aerodynamic research was done with kites before test aircraft, wind tunnels, and computer modelling programs became available. + +The first heavier-than-air craft capable of controlled free-flight were gliders. A glider designed by George Cayley carried out the first true manned, controlled flight in 1853. The first powered and controllable fixed-wing aircraft (the airplane or aeroplane) was invented by Wilbur and Orville Wright. + +Besides the method of propulsion (if any), fixed-wing aircraft are in general characterized by their wing configuration. The most important wing characteristics are: + Number of wings — monoplane, biplane, etc. + Wing support — Braced or cantilever, rigid or flexible. + Wing planform — including aspect ratio, angle of sweep, and any variations along the span (including the important class of delta wings). + Location of the horizontal stabilizer, if any. + Dihedral angle — positive, zero, or negative (anhedral). + +A variable geometry aircraft can change its wing configuration during flight. + +A flying wing has no fuselage, though it may have small blisters or pods. The opposite of this is a lifting body, which has no wings, though it may have small stabilizing and control surfaces. + +Wing-in-ground-effect vehicles are generally not considered aircraft. They "fly" efficiently close to the surface of the ground or water, like conventional aircraft during takeoff. An example is the Russian ekranoplan nicknamed the "Caspian Sea Monster". Man-powered aircraft also rely on ground effect to remain airborne with minimal pilot power, but this is only because they are so underpowered—in fact, the airframe is capable of flying higher. + +Rotorcraft + +Rotorcraft, or rotary-wing aircraft, use a spinning rotor with aerofoil cross-section blades (a rotary wing) to provide lift. Types include helicopters, autogyros, and various hybrids such as gyrodynes and compound rotorcraft. + +Helicopters have a rotor turned by an engine-driven shaft. The rotor pushes air downward to create lift. By tilting the rotor forward, the downward flow is tilted backward, producing thrust for forward flight. Some helicopters have more than one rotor and a few have rotors turned by gas jets at the tips. Some have a tail rotor to counteract the rotation of the main rotor, and to aid directional control. + +Autogyros have unpowered rotors, with a separate power plant to provide thrust. The rotor is tilted backward. As the autogyro moves forward, air blows upward across the rotor, making it spin. This spinning increases the speed of airflow over the rotor, to provide lift. Rotor kites are unpowered autogyros, which are towed to give them forward speed or tethered to a static anchor in high-wind for kited flight. + +Compound rotorcraft have wings that provide some or all of the lift in forward flight. They are nowadays classified as powered lift types and not as rotorcraft. Tiltrotor aircraft (such as the Bell Boeing V-22 Osprey), tiltwing, tail-sitter, and coleopter aircraft have their rotors/propellers horizontal for vertical flight and vertical for forward flight. + +Other methods of lift + + A lifting body is an aircraft body shaped to produce lift. If there are any wings, they are too small to provide significant lift and are used only for stability and control. Lifting bodies are not efficient: they suffer from high drag, and must also travel at high speed to generate enough lift to fly. Many of the research prototypes, such as the Martin Marietta X-24, which led up to the Space Shuttle, were lifting bodies, though the Space Shuttle is not, and some supersonic missiles obtain lift from the airflow over a tubular body. + Powered lift types rely on engine-derived lift for vertical takeoff and landing (VTOL). Most types transition to fixed-wing lift for horizontal flight. Classes of powered lift types include VTOL jet aircraft (such as the Harrier jump jet) and tiltrotors, such as the Bell Boeing V-22 Osprey, among others. A few experimental designs rely entirely on engine thrust to provide lift throughout the whole flight, including personal fan-lift hover platforms and jetpacks. VTOL research designs include the Rolls-Royce Thrust Measuring Rig. + Some rotor wings employ horizontal-axis wings, in which airflow across a spinning rotor generates lift. The Flettner airplane uses a rotating cylinder, obtaining lift from the Magnus effect. The FanWing uses a cross-flow fan, while the mechanically more complex cyclogyro comprises multiple wings which rotate together around a central axis. + The ornithopter obtains thrust by flapping its wings. + +Size and speed extremes + +Size + +The smallest aircraft are toys/recreational items, and nano aircraft. + +The largest aircraft by dimensions and volume (as of 2016) is the long British Airlander 10, a hybrid blimp, with helicopter and fixed-wing features, and reportedly capable of speeds up to , and an airborne endurance of two weeks with a payload of up to . + +The largest aircraft by weight and largest regular fixed-wing aircraft ever built, , was the Antonov An-225 Mriya. That Soviet-built (Ukrainian SSR) six-engine transport of the 1980s was long, with an wingspan. It holds the world payload record, after transporting of goods, and has flown loads commercially. With a maximum loaded weight of , it was also the heaviest aircraft built to date. It could cruise at . The aircraft was destroyed during the Russo-Ukrainian War. + +The largest military airplanes are the Ukrainian Antonov An-124 Ruslan (world's second-largest airplane, also used as a civilian transport), and American Lockheed C-5 Galaxy transport, weighing, loaded, over . The 8-engine, piston/propeller Hughes H-4 Hercules "Spruce Goose" — an American World War II wooden flying boat transport with a greater wingspan (94m/260ft) than any current aircraft and a tail height equal to the tallest (Airbus A380-800 at 24.1m/78ft) — flew only one short hop in the late 1940s and never flew out of ground effect. + +The largest civilian airplanes, apart from the above-noted An-225 and An-124, are the Airbus Beluga cargo transport derivative of the Airbus A300 jet airliner, the Boeing Dreamlifter cargo transport derivative of the Boeing 747 jet airliner/transport (the 747-200B was, at its creation in the 1960s, the heaviest aircraft ever built, with a maximum weight of over ), and the double-decker Airbus A380 "super-jumbo" jet airliner (the world's largest passenger airliner). + +Speeds + +The fastest fixed-wing aircraft and fastest glider, is the Space Shuttle, which re-entered the atmosphere at nearly Mach 25 or + +The fastest recorded powered aircraft flight and fastest recorded aircraft flight of an air-breathing powered aircraft was of the NASA X-43A Pegasus, a scramjet-powered, hypersonic, lifting body experimental research aircraft, at Mach 9.68 or on 16 November 2004. + +Prior to the X-43A, the fastest recorded powered airplane flight, and still the record for the fastest manned powered airplane, was the North American X-15, rocket-powered airplane at Mach 6.7 or 7,274 km/h (4,520 mph) on 3 October 1967. + +The fastest manned, air-breathing powered airplane is the Lockheed SR-71 Blackbird, a U.S. reconnaissance jet fixed-wing aircraft, having reached on 28 July 1976. + +Propulsion + +Unpowered aircraft + +Gliders are heavier-than-air aircraft that do not employ propulsion once airborne. Take-off may be by launching forward and downward from a high location, or by pulling into the air on a tow-line, either by a ground-based winch or vehicle, or by a powered "tug" aircraft. For a glider to maintain its forward air speed and lift, it must descend in relation to the air (but not necessarily in relation to the ground). Many gliders can "soar", i.e., gain height from updrafts such as thermal currents. The first practical, controllable example was designed and built by the British scientist and pioneer George Cayley, whom many recognise as the first aeronautical engineer. Common examples of gliders are sailplanes, hang gliders and paragliders. + +Balloons drift with the wind, though normally the pilot can control the altitude, either by heating the air or by releasing ballast, giving some directional control (since the wind direction changes with altitude). A wing-shaped hybrid balloon can glide directionally when rising or falling; but a spherically shaped balloon does not have such directional control. + +Kites are aircraft that are tethered to the ground or other object (fixed or mobile) that maintains tension in the tether or kite line; they rely on virtual or real wind blowing over and under them to generate lift and drag. Kytoons are balloon-kite hybrids that are shaped and tethered to obtain kiting deflections, and can be lighter-than-air, neutrally buoyant, or heavier-than-air. + +Powered aircraft + +Powered aircraft have one or more onboard sources of mechanical power, typically aircraft engines although rubber and manpower have also been used. Most aircraft engines are either lightweight reciprocating engines or gas turbines. Engine fuel is stored in tanks, usually in the wings but larger aircraft also have additional fuel tanks in the fuselage. + +Propeller aircraft + +Propeller aircraft use one or more propellers (airscrews) to create thrust in a forward direction. The propeller is usually mounted in front of the power source in tractor configuration but can be mounted behind in pusher configuration. Variations of propeller layout include contra-rotating propellers and ducted fans. + +Many kinds of power plant have been used to drive propellers. Early airships used man power or steam engines. The more practical internal combustion piston engine was used for virtually all fixed-wing aircraft until World War II and is still used in many smaller aircraft. Some types use turbine engines to drive a propeller in the form of a turboprop or propfan. Human-powered flight has been achieved, but has not become a practical means of transport. Unmanned aircraft and models have also used power sources such as electric motors and rubber bands. + +Jet aircraft + +Jet aircraft use airbreathing jet engines, which take in air, burn fuel with it in a combustion chamber, and accelerate the exhaust rearwards to provide thrust. + +Different jet engine configurations include the turbojet and turbofan, sometimes with the addition of an afterburner. Those with no rotating turbomachinery include the pulsejet and ramjet. These mechanically simple engines produce no thrust when stationary, so the aircraft must be launched to flying speed using a catapult, like the V-1 flying bomb, or a rocket, for example. Other engine types include the motorjet and the dual-cycle Pratt & Whitney J58. + +Compared to engines using propellers, jet engines can provide much higher thrust, higher speeds and, above about , greater efficiency. They are also much more fuel-efficient than rockets. As a consequence nearly all large, high-speed or high-altitude aircraft use jet engines. + +Rotorcraft + +Some rotorcraft, such as helicopters, have a powered rotary wing or rotor, where the rotor disc can be angled slightly forward so that a proportion of its lift is directed forwards. The rotor may, like a propeller, be powered by a variety of methods such as a piston engine or turbine. Experiments have also used jet nozzles at the rotor blade tips. + +Other types of powered aircraft + Rocket-powered aircraft have occasionally been experimented with, and the Messerschmitt Me 163 Komet fighter even saw action in the Second World War. Since then, they have been restricted to research aircraft, such as the North American X-15, which traveled up into space where air-breathing engines cannot work (rockets carry their own oxidant). Rockets have more often been used as a supplement to the main power plant, typically for the rocket-assisted take off of heavily loaded aircraft, but also to provide high-speed dash capability in some hybrid designs such as the Saunders-Roe SR.53. + The ornithopter obtains thrust by flapping its wings. It has found practical use in a model hawk used to freeze prey animals into stillness so that they can be captured, and in toy birds. + +Design and construction +Aircraft are designed according to many factors such as customer and manufacturer demand, safety protocols and physical and economic constraints. For many types of aircraft the design process is regulated by national airworthiness authorities. + +The key parts of an aircraft are generally divided into three categories: + The structure ("airframe") comprises the main load-bearing elements and associated equipment, as well as flight controls. + The propulsion system ("powerplant") (if it is powered) comprises the power source and associated equipment, as described above. + The avionics comprise the electrical and electronic control, navigation and communication systems. + +Structure +The approach to structural design varies widely between different types of aircraft. Some, such as paragliders, comprise only flexible materials that act in tension and rely on aerodynamic pressure to hold their shape. A balloon similarly relies on internal gas pressure, but may have a rigid basket or gondola slung below it to carry its payload. Early aircraft, including airships, often employed flexible doped aircraft fabric covering to give a reasonably smooth aeroshell stretched over a rigid frame. Later aircraft employed semi-monocoque techniques, where the skin of the aircraft is stiff enough to share much of the flight loads. In a true monocoque design there is no internal structure left. + +The key structural parts of an aircraft depend on what type it is. + +Aerostats + +Lighter-than-air types are characterised by one or more gasbags, typically with a supporting structure of flexible cables or a rigid framework called its hull. Other elements such as engines or a gondola may also be attached to the supporting structure. + +Aerodynes + +Heavier-than-air types are characterised by one or more wings and a central fuselage. The fuselage typically also carries a tail or empennage for stability and control, and an undercarriage for takeoff and landing. Engines may be located on the fuselage or wings. On a fixed-wing aircraft the wings are rigidly attached to the fuselage, while on a rotorcraft the wings are attached to a rotating vertical shaft. Smaller designs sometimes use flexible materials for part or all of the structure, held in place either by a rigid frame or by air pressure. The fixed parts of the structure comprise the airframe. + +Power + +The source of motive power for an aircraft is normally called the powerplant, and includes engine or motor, propeller or rotor, (if any), jet nozzles and thrust reversers (if any), and accessories essential to the functioning of the engine or motor (e.g.: starter, ignition system, intake system, exhaust system, fuel system, lubrication system, engine cooling system, and engine controls). + +Powered aircraft are typically powered by internal combustion engines (piston or turbine) burning fossil fuels -- typically gasoline (avgas) or jet fuel. A very few are powered by rocket power, ramjet propulsion, or by electric motors, or by internal combustion engines of other types, or using other fuels. A very few have been powered, for short flights, by human muscle energy (e.g.: Gossamer Condor). + +Avionics + +The avionics comprise any electronic aircraft flight control systems and related equipment, including electronic cockpit instrumentation, navigation, radar, monitoring, and communications systems. + +Flight characteristics + +Flight envelope + +The flight envelope of an aircraft refers to its approved design capabilities in terms of airspeed, load factor and altitude. The term can also refer to other assessments of aircraft performance such as maneuverability. When an aircraft is abused, for instance by diving it at too-high a speed, it is said to be flown outside the envelope, something considered foolhardy since it has been taken beyond the design limits which have been established by the manufacturer. Going beyond the envelope may have a known outcome such as flutter or entry to a non-recoverable spin (possible reasons for the boundary). + +Range + +The range is the distance an aircraft can fly between takeoff and landing, as limited by the time it can remain airborne. + +For a powered aircraft the time limit is determined by the fuel load and rate of consumption. + +For an unpowered aircraft, the maximum flight time is limited by factors such as weather conditions and pilot endurance. Many aircraft types are restricted to daylight hours, while balloons are limited by their supply of lifting gas. The range can be seen as the average ground speed multiplied by the maximum time in the air. + +The Airbus A350-900ULR is now the longest range airliner. + +Flight dynamics + +Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation around three axes which pass through the vehicle's center of gravity, known as pitch, roll, and yaw. + Roll is a rotation about the longitudinal axis (equivalent to the rolling or heeling of a ship) giving an up-down movement of the wing tips measured by the roll or bank angle. + Pitch is a rotation about the sideways horizontal axis giving an up-down movement of the aircraft nose measured by the angle of attack. + Yaw is a rotation about the vertical axis giving a side-to-side movement of the nose known as sideslip. + +Flight dynamics is concerned with the stability and control of an aircraft's rotation about each of these axes. + +Stability + +An aircraft that is unstable tends to diverge from its intended flight path and so is difficult to fly. A very stable aircraft tends to stay on its flight path and is difficult to maneuver. Therefore, it is important for any design to achieve the desired degree of stability. Since the widespread use of digital computers, it is increasingly common for designs to be inherently unstable and rely on computerised control systems to provide artificial stability. + +A fixed wing is typically unstable in pitch, roll, and yaw. Pitch and yaw stabilities of conventional fixed wing designs require horizontal and vertical stabilisers, which act similarly to the feathers on an arrow. These stabilizing surfaces allow equilibrium of aerodynamic forces and to stabilise the flight dynamics of pitch and yaw. They are usually mounted on the tail section (empennage), although in the canard layout, the main aft wing replaces the canard foreplane as pitch stabilizer. Tandem wing and tailless aircraft rely on the same general rule to achieve stability, the aft surface being the stabilising one. + +A rotary wing is typically unstable in yaw, requiring a vertical stabiliser. + +A balloon is typically very stable in pitch and roll due to the way the payload is slung underneath the center of lift. + +Control +Flight control surfaces enable the pilot to control an aircraft's flight attitude and are usually part of the wing or mounted on, or integral with, the associated stabilizing surface. Their development was a critical advance in the history of aircraft, which had until that point been uncontrollable in flight. + +Aerospace engineers develop control systems for a vehicle's orientation (attitude) about its center of mass. The control systems include actuators, which exert forces in various directions, and generate rotational forces or moments about the aerodynamic center of the aircraft, and thus rotate the aircraft in pitch, roll, or yaw. For example, a pitching moment is a vertical force applied at a distance forward or aft from the aerodynamic center of the aircraft, causing the aircraft to pitch up or down. Control systems are also sometimes used to increase or decrease drag, for example to slow the aircraft to a safe speed for landing. + +The two main aerodynamic forces acting on any aircraft are lift supporting it in the air and drag opposing its motion. Control surfaces or other techniques may also be used to affect these forces directly, without inducing any rotation. + +Environmental impact + +Aircraft permit long distance, high speed travel and may be a more fuel efficient mode of transportation in some circumstances. Aircraft have environmental and climate impacts beyond fuel efficiency considerations, however. They are also relatively noisy compared to other forms of travel and high altitude aircraft generate contrails, which experimental evidence suggests may alter weather patterns. + +Uses for aircraft +Aircraft are produced in several different types optimized for various uses; military aircraft, which includes not just combat types but many types of supporting aircraft, and civil aircraft, which include all non-military types, experimental and model. + +Military + +A military aircraft is any aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat: + + Combat aircraft are aircraft designed to destroy enemy equipment using its own armament. Combat aircraft divide broadly into fighters and bombers, with several in-between types, such as fighter-bombers and attack aircraft, including attack helicopters. + Non-combat aircraft are not designed for combat as their primary function, but may carry weapons for self-defense. Non-combat roles include search and rescue, reconnaissance, observation, transport, training, and aerial refueling. These aircraft are often variants of civil aircraft. + +Most military aircraft are powered heavier-than-air types. Other types, such as gliders and balloons, have also been used as military aircraft; for example, balloons were used for observation during the American Civil War and World War I, and military gliders were used during World War II to land troops. + +Civil + +Civil aircraft divide into commercial and general types, however there are some overlaps. + +Commercial aircraft include types designed for scheduled and charter airline flights, carrying passengers, mail and other cargo. The larger passenger-carrying types are the airliners, the largest of which are wide-body aircraft. Some of the smaller types are also used in general aviation, and some of the larger types are used as VIP aircraft. + +General aviation is a catch-all covering other kinds of private (where the pilot is not paid for time or expenses) and commercial use, and involving a wide range of aircraft types such as business jets (bizjets), trainers, homebuilt, gliders, warbirds and hot air balloons to name a few. The vast majority of aircraft today are general aviation types. + +Experimental + +An experimental aircraft is one that has not been fully proven in flight, or that carries a Special Airworthiness Certificate, called an Experimental Certificate in United States parlance.

He is known for creating dynamite as well as having bequeathed his fortune to establish the Nobel Prize. He also made several important contributions to science, holding 355 patents in his lifetime. Nobel's most famous invention was dynamite, an explosive using nitroglycerin; it was patented in 1867. + +Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at the age of 24. He embarked on many business ventures with his family, most notably owning the company Bofors, which was an iron and steel producer that he had developed into a major manufacturer of cannons and other armaments. + +Nobel was later inspired to donate his fortune to the Nobel Prize institution, which would annually recognize those who "conferred the greatest benefit to humankind". The synthetic element nobelium was named after him, and his name and legacy also survives in companies such as Dynamit Nobel and AkzoNobel, which descend from mergers with companies he founded. + +Nobel was elected a member of the Royal Swedish Academy of Sciences, which, pursuant to his will, would be responsible for choosing the Nobel laureates in physics and in chemistry. + +Personal life + +Early life and education + +Alfred Nobel was born in Stockholm, United Kingdoms of Sweden and Norway on 21 October 1833. He was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Karolina Andriette Nobel (née Ahlsell 1805–1889). The couple married in 1827 and had eight children. The family was impoverished and only Alfred and his three brothers survived beyond childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn, the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.Following various business failures caused by the loss of some barges of building material, Immanuel Nobel was forced into bankruptcy, Nobel's father moved to Saint Petersburg, Russia, and grew successful there as a manufacturer of machine tools and explosives. He invented the veneer lathe (which made possible the production of modern plywood) and started work on the torpedo. In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German and Russian. For 18 months, from 1841 to 1842, Nobel went to the only school he ever attended as a child, in Stockholm. + +Nobel gained proficiency in Swedish, French, Russian, English, German, and Italian. He also developed sufficient literary skill to write poetry in English. His Nemesis is a prose tragedy in four acts about the Italian noblewoman Beatrice Cenci. It was printed while he was dying, but the entire stock was destroyed immediately after his death except for three copies, being regarded as scandalous and blasphemous. It was published in Sweden in 2003 and has been translated into Slovenian, French, Italian, and Spanish. + +Religion +Nobel was Lutheran and regularly attended the Church of Sweden Abroad during his Paris years, led by pastor Nathan Söderblom who received the Nobel Peace Prize in 1930. He was an agnostic in youth and became an atheist later in life, though he still donated generously to the Church. + +Health and relationships +Nobel traveled for much of his business life, maintaining companies in Europe and America while keeping a home in Paris from 1873 to 1891. He remained a solitary character, given to periods of depression. He remained unmarried, although his biographers note that he had at least three loves, the first in Russia with a girl named Alexandra who rejected his proposal. In 1876, Austro-Bohemian Countess Bertha Kinsky became his secretary, but she left him after a brief stay to marry her previous lover Baron Arthur Gundaccar von Suttner. Her contact with Nobel was brief, yet she corresponded with him until his death in 1896, and probably influenced his decision to include a peace prize in his will. She was awarded the 1905 Nobel Peace prize "for her sincere peace activities". Nobel's longest-lasting relationship was with Sofija Hess from Celje whom he met in 1876 in Baden near Vienna, where she worked as an employee in a flower shop. The liaison lasted for 18 years. + +Residences +In the years of 1865 to 1873, Alfred Nobel had his home in Krümmel, Hamburg, he afterward moved to a house in the Avenue Malakoff in Paris that same year. + +In 1894, when he acquired Bofors-Gullspång, the Björkborn Manor was included, he stayed at his manor house in Sweden during the summers. The manor house became his very last residence in Sweden and has after his death functioned as a museum. + +Alfred Nobel died on 10 December 1896, in Sanremo, Italy, at his very last residence, Villa Nobel, overlooking the Mediterranean Sea. + +Scientific career +As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work. There he met Ascanio Sobrero, who had invented nitroglycerin three years before. Sobrero strongly opposed the use of nitroglycerin because it was unpredictable, exploding when subjected to variable heat or pressure. But Nobel became interested in finding a way to control and use nitroglycerin as a commercially usable explosive; it had much more power than gunpowder. In 1851 at age 18, he went to the United States for one year to study, working for a short period under Swedish-American inventor John Ericsson, who designed the American Civil War ironclad, USS Monitor. Nobel filed his first patent, an English patent for a gas meter, in 1857, while his first Swedish patent, which he received in 1863, was on "ways to prepare gunpowder".The family factory produced armaments for the Crimean War (1853–1856), but had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerin. Nobel invented a detonator in 1863, and in 1865 designed the blasting cap. + +On 3 September 1864, a shed used for preparation of nitroglycerin exploded at the factory in Heleneborg, Stockholm, Sweden, killing five people, including Nobel's younger brother Emil. Fazed by the accident, Nobel founded the company Nitroglycerin Aktiebolaget AB in Vinterviken so that he could continue to work in a more isolated area. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875, Nobel invented gelignite, more stable and powerful than dynamite, and in 1887, patented ballistite, a predecessor of cordite. + +Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893. + +Nobel's brothers Ludvig and Robert founded the oil company Branobel and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. It operated mainly in Baku, Azerbaijan, but also in Cheleken, Turkmenistan. During his life, Nobel was issued 355 patents internationally, and by his death, his business had established more than 90 armaments factories, despite his apparently pacifist character. + +Inventions + +Nobel found that when nitroglycerin was incorporated in an absorbent inert substance like kieselguhr (diatomaceous earth) it became safer and more convenient to handle, and this mixture he patented in 1867 as "dynamite". Nobel demonstrated his explosive for the first time that year, at a quarry in Redhill, Surrey, England. In order to help reestablish his name and improve the image of his business from the earlier controversies associated with dangerous explosives, Nobel had also considered naming the highly powerful substance "Nobel's Safety Powder", but settled with Dynamite instead, referring to the Greek word for "power" (). + +Nobel later combined nitroglycerin with various nitrocellulose compounds, similar to collodion, but settled on a more efficient recipe combining another nitrate explosive, and obtained a transparent, jelly-like substance, which was a more powerful explosive than dynamite. Gelignite, or blasting gelatin, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances. Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds. It was adopted as the standard technology for mining in the "Age of Engineering", bringing Nobel a great amount of financial success, though at a cost to his health. An offshoot of this research resulted in Nobel's invention of ballistite, the precursor of many modern smokeless powder explosives and still used as a rocket propellant. + +Nobel Prize + +There is a well known story about the origin of the Nobel Prize, although historians have been unable to verify it and some dismiss the story as a myth. In 1888, the death of his brother Ludvig supposedly caused several newspapers to publish obituaries of Alfred in error. One French newspaper condemned him for his invention of military explosives—in many versions of the story, dynamite is quoted, although this was mainly used for civilian applications—and this is said to have brought about his decision to leave a better legacy after his death. The obituary stated, ("The merchant of death is dead"), and went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday." Nobel read the obituary and was appalled at the idea that he would be remembered in this way. His decision to posthumously donate the majority of his wealth to found the Nobel Prize has been credited to him wanting to leave behind a better legacy. However, it has been questioned whether or not the obituary in question actually existed. + +On 27 November 1895, at the Swedish-Norwegian Club in Paris, Nobel signed his last will and testament and set aside the bulk of his estate to establish the Nobel Prizes, to be awarded annually without distinction of nationality. After taxes and bequests to individuals, Nobel's will allocated 94% of his total assets, 31,225,000 Swedish kronor, to establish the five Nobel Prizes. This converted to £1,687,837 (GBP) at the time. In 2012, the capital was worth around SEK 3.1 billion (US$472 million, EUR 337 million), which is almost twice the amount of the initial capital, taking inflation into account. + +The first three of these prizes are awarded for eminence in physical science, in chemistry and in medical science or physiology; the fourth is for literary work "in an ideal direction" and the fifth prize is to be given to the person or society that renders the greatest service to the cause of international fraternity, in the suppression or reduction of standing armies, or in the establishment or furtherance of peace congresses. + +The formulation for the literary prize being given for a work "in an ideal direction" ( in Swedish), is cryptic and has caused much confusion. For many years, the Swedish Academy interpreted "ideal" as "idealistic" () and used it as a reason not to give the prize to important but less romantic authors, such as Henrik Ibsen and Leo Tolstoy. This interpretation has since been revised, and the prize has been awarded to, for example, Dario Fo and José Saramago, who do not belong to the camp of literary idealism. + +There was room for interpretation by the bodies he had named for deciding on the physical sciences and chemistry prizes, given that he had not consulted them before making the will. In his one-page testament, he stipulated that the money go to discoveries or inventions in the physical sciences and to discoveries or improvements in chemistry. He had opened the door to technological awards, but had not left instructions on how to deal with the distinction between science and technology. Since the deciding bodies he had chosen were more concerned with the former, the prizes went to scientists more often than engineers, technicians or other inventors. + +Sweden's central bank Sveriges Riksbank celebrated its 300th anniversary in 1968 by donating a large sum of money to the Nobel Foundation to be used to set up a sixth prize in the field of economics in honor of Alfred Nobel. In 2001, Alfred Nobel's great-great-nephew, Peter Nobel (born 1931), asked the Bank of Sweden to differentiate its award to economists given "in Alfred Nobel's memory" from the five other awards. This request added to the controversy over whether the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel is actually a legitimate "Nobel Prize". + +Death + +Nobel was accused of high treason against France for selling Ballistite to Italy, so he moved from Paris to Sanremo, Italy, in 1891. On 10 December 1896, he suffered a stroke and was partially paralyzed to where he could speak only his native tongue. Nobel was surrounded by his paid servants at the time of his death who didn't speak his native tongue so he wrote, "how sad it is to be without a friend who could whisper a consoling word and would one day gently close one's eyes." He had left most of his wealth in trust, unbeknownst to his family, in order to fund the Nobel Prize awards. He is buried in Norra begravningsplatsen in Stockholm. + +Monuments and legacy +The Monument to Alfred Nobel (, ) in Saint Petersburg is located along the Bolshaya Nevka River on Petrogradskaya Embankment. It was dedicated in 1991 to mark the 90th anniversary of the first Nobel Prize presentation. Diplomat Thomas Bertelman and Professor Arkady Melua were initiators of the creation of the monument (1989). Professor A. Melua has provided funds for the establishment of the monument (J.S.Co. "Humanistica", 1990–1991). The abstract metal sculpture was designed by local artists Sergey Alipov and Pavel Shevchenko, and appears to be an explosion or branches of a tree. Petrogradskaya Embankment is the street where Nobel's family lived until 1859. + +Criticism of Nobel focuses on his leading role in weapons manufacturing and sales, and some question his motives in creating his prizes, suggesting they are intended to improve his reputation. + +References + +Further reading + Schück, H, and Sohlman, R., (1929).

He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. + +Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf; profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. + +Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Bell also had a strong influence on the National Geographic Society and its magazine while serving as the second president from January 7, 1898, until 1903. + +Beyond his work in engineering, Bell had a deep interest in the emerging science of heredity. His work in this area has been called "the soundest, and most useful study of human heredity proposed in nineteenth-century America...Bell's most notable contribution to basic science, as distinct from invention." + +Early life +Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at South Charlotte Street, and has a stone inscription marking it as Bell's birthplace. He had two brothers: Melville James Bell (1845–1870) and Edward Charles Bell (1848–1867), both of whom would die of tuberculosis. His father was Alexander Melville Bell, a phonetician, and his mother was Eliza Grace Bell (née Symonds). Born as just "Alexander Bell", at age 10, he made a plea to his father to have a middle name like his two brothers. For his 11th birthday, his father acquiesced and allowed him to adopt the name "Graham", chosen out of respect for Alexander Graham, a Canadian being treated by his father who had become a family friend. To close relatives and friends he remained "Aleck". Bell and his siblings attended a Presbyterian Church in their youth. + +First invention +As a child, Bell displayed a curiosity about his world; he gathered botanical specimens and ran experiments at an early age. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. At the age of 12, Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation at the mill and used steadily for a number of years. In return, Ben's father John Herdman gave both boys the run of a small workshop in which to "invent". + +From his early years, Bell showed a sensitive nature and a talent for art, poetry, and music that was encouraged by his mother. With no formal training, he mastered the piano and became the family's pianist. Despite being normally quiet and introspective, he revelled in mimicry and "voice tricks" akin to ventriloquism that continually entertained family guests during their occasional visits. Bell was also deeply affected by his mother's gradual deafness (she began to lose her hearing when he was 12), and learned a manual finger language so he could sit at her side and tap out silently the conversations swirling around the family parlour. He also developed a technique of speaking in clear, modulated tones directly into his mother's forehead wherein she would hear him with reasonable clarity. Bell's preoccupation with his mother's deafness led him to study acoustics. + +His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. His father published a variety of works on the subject, several of which are still well known, especially his The Standard Elocutionist (1860), which appeared in Edinburgh in 1868. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. In this treatise, his father explains his methods of how to instruct deaf-mutes (as they were then known) to articulate words and read other people's lip movements to decipher meaning. Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. Bell became so proficient that he became a part of his father's public demonstrations and astounded audiences with his abilities. He could decipher Visible Speech representing virtually every language, including Latin, Scottish Gaelic, and even Sanskrit, accurately reciting written tracts without any prior knowledge of their pronunciation. + +Education +As a young child, Bell, like his brothers, received his early schooling at home from his father. At an early age, he was enrolled at the Royal High School, Edinburgh, which he left at the age of 15, having completed only the first four forms. His school record was undistinguished, marked by absenteeism and lacklustre grades. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. Upon leaving school, Bell travelled to London to live with his grandfather, Alexander Bell, on Harrington Square. During the year he spent with his grandfather, a love of learning was born, with long hours spent in serious discussion and study. The elder Bell took great efforts to have his young pupil learn to speak clearly and with conviction, the attributes that his pupil would need to become a teacher himself. At the age of 16, Bell secured a position as a "pupil-teacher" of elocution and music, in Weston House Academy at Elgin, Moray, Scotland. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and £10 per session. The following year, he attended the University of Edinburgh, joining his older brother Melville who had enrolled there the previous year. In 1868, not long before he departed for Canada with his family, Bell completed his matriculation exams and was accepted for admission to University College London. + +First experiments with sound +His father encouraged Bell's interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. The rudimentary "mechanical man" simulated a human voice. Bell was fascinated by the machine and after he obtained a copy of von Kempelen's book, published in German, and had laboriously translated it, he and his older brother Melville built their own automaton head. Their father, highly interested in their project, offered to pay for any supplies and spurred the boys on with the enticement of a "big prize" if they were successful. While his brother constructed the throat and larynx, Bell tackled the more difficult task of recreating a realistic skull. His efforts resulted in a remarkably lifelike head that could "speak", albeit only a few words. The boys would carefully adjust the "lips" and when a bellows forced air through the windpipe, a very recognizable Mama ensued, to the delight of neighbours who came to see the Bell invention. + +Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, Trouve. After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". With little convincing, visitors believed his dog could articulate "How are you, grandmama?" Indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". These initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance. + +At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father. Ellis immediately wrote back indicating that the experiments were similar to existing work in Germany, and also lent Bell a copy of Hermann von Helmholtz's work, The Sensations of Tone as a Physiological Basis for the Theory of Music. + +Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork "contraption", Bell pored over the German scientist's book. Working from his own erroneous mistranslation of a French edition, Bell fortuitously then made a deduction that would be the underpinning of all his future work on transmitting sound, reporting: "Without knowing much about the subject, it seemed to me that if vowel sounds could be produced by electrical means, so could consonants, so could articulate speech." He also later remarked: "I thought that Helmholtz had done it ... and that my failure was due only to my ignorance of electricity. It was a valuable blunder ... If I had been able to read German in those days, I might never have commenced my experiments!" + +Family tragedy +In 1865, when the Bell family moved to London, Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment. Bell concentrated on experimenting with electricity to convey sound and later installed a telegraph wire from his room in Somerset College to that of a friend. Throughout late 1867, his health faltered mainly through exhaustion. His younger brother, Edward "Ted", was similarly affected by tuberculosis. While Bell recovered (by then referring to himself in correspondence as "A. G. Bell") and served the next year as an instructor at Somerset College, Bath, England, his brother's condition deteriorated. Edward would never recover. Upon his brother's death, Bell returned home in 1867. His older brother Melville had married and moved out. With aspirations to obtain a degree at University College London, Bell considered his next years as preparation for the degree examinations, devoting his spare time at his family's residence to studying. + +Helping his father in Visible Speech demonstrations and lectures brought Bell to Susanna E. Hull's private school for the deaf in South Kensington, London. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. While his older brother seemed to achieve success on many fronts including opening his own elocution school, applying for a patent on an invention, and starting a family, Bell continued as a teacher. However, in May 1870, Melville died from complications due to tuberculosis, causing a family crisis. His father had also experienced a debilitating illness earlier in life and had been restored to health by a convalescence in Newfoundland. Bell's parents embarked upon a long-planned move when they realized that their remaining son was also sickly. Acting decisively, Alexander Melville Bell asked Bell to arrange for the sale of all the family property, conclude all of his brother's affairs (Bell took over his last student, curing a pronounced lisp), and join his father and mother in setting out for the "New World". Reluctantly, Bell also had to conclude a relationship with Marie Eccleston, who, as he had surmised, was not prepared to leave England with him. + +Canada + +In 1870, 23-year-old Bell travelled with his parents and his brother's widow, Caroline Margaret Ottaway, to Paris, Ontario, to stay with Thomas Henderson, a Baptist minister and family friend. The Bell family soon purchased a farm of at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario. The property consisted of an orchard, large farmhouse, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River. + +At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his "dreaming place", a large hollow nestled in trees at the back of the property above the river. Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved. He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols. For his work, Bell was awarded the title of Honorary Chief and participated in a ceremony where he donned a Mohawk headdress and danced traditional dances. + +After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. He also modified a melodeon (a type of pump organ) so that it could transmit its music electrically over a distance. Once the family was settled in, both Bell and his father made plans to establish a teaching practice and in 1871, he accompanied his father to Montreal, where Melville was offered a position to teach his System of Visible Speech. + +Work with the deaf + +Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (later to become the public Horace Mann School for the Deaf) to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favour of his son. Travelling to Boston in April 1871, Bell proved successful in training the school's instructors. He was subsequently asked to repeat the programme at the American Asylum for Deaf-mutes in Hartford, Connecticut, and the Clarke School for the Deaf in Northampton, Massachusetts. + +Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph". The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed. + +Unsure of his future, he contemplated returning to London to complete his studies, but decided to return to Boston as a teacher. His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. While he was working as a private tutor, one of his pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. She was later to say that Bell dedicated his life to the penetration of that "inhuman silence which separates and estranges". In 1893, Keller performed the sod-breaking ceremony for the construction of Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf". + +Throughout his lifetime, Bell sought to integrate the deaf and hard of hearing with the hearing world. Bell encouraged speech therapy and lip reading over sign language. He outlined this in a 1898 paper detailing his belief that with resources and effort, the deaf could be taught to read lips and speak (known as oralism) thus enabling their integration within the wider society. Bell has been criticised by members of the Deaf community for supporting ideas that could cause the closure of dozens of deaf schools, and what some consider eugenicist ideas. Bell did not support a ban on deaf people marrying each other, an idea articulated by the National Association of the Deaf (United States). Although, in his memoir Memoir upon the Formation of a Deaf Variety of the Human Race, Bell observed that if deaf people tended to marry other deaf people, this could result in the emergence of a "deaf race". Ultimately, in 1880, the Second International Congress on Education of the Deaf passed a resolution preferring the teaching of oral communication rather than signing in schools. + +Continuing experimentation + +In 1872, Bell became professor of Vocal Physiology and Elocution at the Boston University School of Oratory. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. He continued his research in sound and endeavored to find a way to transmit musical notes and articulate speech, but although absorbed by his experiments, he found it difficult to devote enough time to experimentation. While days and evenings were occupied by his teaching and private classes, Bell began to stay awake late into the night, running experiment after experiment in rented facilities at his boarding house. Keeping "night owl" hours, he worried that his work would be discovered and took great pains to lock up his notebooks and laboratory equipment. Bell had a specially made table where he could place his notes and equipment inside a locking cover. Worse still, his health deteriorated as he had severe headaches. Returning to Boston in fall 1873, Bell made a far-reaching decision to concentrate on his experiments in sound. + +Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old "Georgie" Sanders, deaf from birth, and 15-year-old Mabel Hubbard. Each pupil would play an important role in the next developments. George's father, Thomas Sanders, a wealthy businessman, offered Bell a place to stay in nearby Salem with Georgie's grandmother, complete with a room to "experiment". Although the offer was made by George's mother and followed the year-long arrangement in 1872 where her son and his nurse had moved to quarters next to Bell's boarding house, it was clear that Mr. Sanders was backing the proposal. The arrangement was for teacher and student to continue their work together, with free room and board thrown in. Mabel was a bright, attractive girl who was ten years Bell's junior but became the object of his affection. Having lost her hearing after a near-fatal bout of scarlet fever close to her fifth birthday, she had learned to read lips but her father, Gardiner Greene Hubbard, Bell's benefactor and personal friend, wanted her to work directly with her teacher. + +The telephone + +By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas. + +In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok. + +In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that. + +With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the reed's overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech. + +The race to the patent office + +In 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain (Britain would issue patents only for discoveries not previously patented elsewhere). + +Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. On February 14, 1876, Gray filed a caveat with the U.S. Patent Office for a telephone design that used a water transmitter. That same morning, Bell's lawyer filed Bell's application with the patent office. There is considerable debate about who arrived first and Gray later challenged the primacy of Bell's patent. Bell was in Boston on February 14 and did not arrive in Washington until February 26. + +Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat. + +On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray's design. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the sentence "Mr. Watson—Come here—I want to see you" into the liquid transmitter, Watson, listening at the receiving end in an adjoining room, heard the words clearly. + +Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use. + +The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in his previous application in which he described a cup of mercury, not water. He had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone. + +The patent examiner, Zenas Fisk Wilber, later stated in an affidavit that he was an alcoholic who was much in debt to Bell's lawyer, Marcellus Bailey, with whom he had served in the Civil War. He claimed he showed Gray's patent caveat to Bailey. Wilber also claimed (after Bell arrived in Washington D.C. from Boston) that he showed Gray's caveat to Bell and that Bell paid him $100 (). Bell claimed they discussed the patent only in general terms, although in a letter to Gray, Bell admitted that he learned some of the technical details. Bell denied in an affidavit that he ever gave Wilber any money. + +Later developments + +On March 10, 1876, Bell used "the instrument" in Boston to call Thomas Watson who was in another room but out of earshot. He said, "Mr. Watson, come here – I want to see you" and Watson soon appeared at his side. + +Continuing his experiments in Brantford, Bell brought home a working model of his telephone. On August 3, 1876, from the telegraph office in Brantford, Ontario, Bell sent a tentative telegram to the village of Mount Pleasant distant, indicating that he was ready. He made a telephone call via telegraph wires and faint voices were heard replying. The following night, he amazed guests as well as his family with a call between the Bell Homestead and the office of the Dominion Telegraph Company in Brantford along an improvised wire strung up along telegraph lines and fences, and laid through a tunnel. This time, guests at the household distinctly heard people in Brantford reading and singing. The third test on August 10, 1876, was made via the telegraph line between Brantford and Paris, Ontario, distant. This test was said by many sources to be the "world's first long-distance call". The final test certainly proved that the telephone could work over long distances, at least as a one-way call. + +The first two-way (reciprocal) conversation over a line occurred between Cambridge and Boston (roughly 2.5 miles) on October 9, 1876. During that conversation, Bell was on Kilby Street in Boston and Watson was at the offices of the Walworth Manufacturing Company. + +Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000, equal to $ today. The president of Western Union balked, countering that the telephone was nothing but a toy. Two years later, he told colleagues that if he could get the patent for $25 million (equal to $ today), he would consider it a bargain. By then, the Bell company no longer wanted to sell the patent. Bell's investors would become millionaires while he fared well from residuals and at one point had assets of nearly one million dollars. + +Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public. A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. Influential visitors to the exhibition included Emperor Pedro II of Brazil. One of the judges at the Exhibition, Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, described the telephone as "the greatest by far of all the marvels of the electric telegraph". + +On January 14, 1878, at Osborne House, on the Isle of Wight, Bell demonstrated the device to Queen Victoria, placing calls to Cowes, Southampton and London. These were the first publicly witnessed long-distance telephone calls in the UK. The queen considered the process to be "quite extraordinary" although the sound was "rather faint". She later asked to buy the equipment that was used, but Bell offered to make "a set of telephones" specifically for her. + +The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. Bell Company engineers made numerous other improvements to the telephone, which emerged as one of the most successful products ever. In 1879, the Bell company acquired Edison's patents for the carbon microphone from Western Union. This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. + +Emperor Pedro II of Brazil was the first person to buy stock in Bell's company, the Bell Telephone Company. One of the first telephones in a private residence was installed in his palace in Petrópolis, his summer retreat from Rio de Janeiro. + +In January 1915, Bell made the first ceremonial transcontinental telephone call. Calling from the AT&T head office at 15 Dey Street in New York City, Bell was heard by Thomas Watson at 333 Grant Avenue in San Francisco. The New York Times reported: + +Competitors +As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court, but none was successful in establishing priority over the original Bell patent, and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. Bell's laboratory notes and family letters were the key to establishing a long lineage to his experiments. The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims. + +On January 13, 1887, the U.S. Government moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation. After a series of decisions and reversals, the Bell company won a decision in the Supreme Court, though a couple of the original claims from the lower court cases were left undecided. By the time that the trial wound its way through nine years of legal battles, the U.S. prosecuting attorney had died and the two Bell patents (No. 174,465 dated March 7, 1876, and No. 186,787 dated January 30, 1877) were no longer in effect, although the presiding judges agreed to continue the proceedings due to the case's importance as a precedent. With a change in administration and charges of conflict of interest (on both sides) arising from the original trial, the US Attorney General dropped the lawsuit on November 30, 1897, leaving several issues undecided on the merits. + +During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hope of establishing his invention's priority. Meucci's testimony in this case was disputed due to a lack of material evidence for his inventions, as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002, stated that Meucci's "work in the invention of the telephone should be acknowledged". This did not put an end to the still-contentious issue. Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions. + +The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell delayed the German patent application, the electrical firm of Siemens & Halske set up a rival manufacturer of Bell telephones under their own patent. The Siemens company produced near-identical copies of the Bell telephone without having to pay royalties. The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. + +Family life + +On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (1857–1923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancée was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children: + Elsie May Bell (1878–1964) who married Gilbert Hovey Grosvenor of National Geographic fame. + Marian Hubbard Bell (1880–1962) who was referred to as "Daisy". Married David Fairchild. + Two sons who died in infancy (Edward in 1881 and Robert in 1883). +The Bell family home was in Cambridge, Massachusetts, until 1880 when Bell's father-in-law bought a house in Washington, D.C.; in 1882 he bought a home in the same city for Bell's family, so they could be with him while he attended to the numerous court cases involving patent disputes. + +Bell was a British subject throughout his early life in Scotland and later in Canada until 1882 when he became a naturalized citizen of the United States. In 1915, he characterized his status as: "I am not one of those hyphenated Americans who claim allegiance to two countries." Despite this declaration, Bell has been proudly claimed as a "native son" by all three countries he resided in: the United States, Canada, and the United Kingdom. + +By 1885, a new summer retreat was contemplated. That summer, the Bells had a vacation on Cape Breton Island in Nova Scotia, spending time at the small village of Baddeck. Returning in 1886, Bell started building an estate on a point across from Baddeck, overlooking Bras d'Or Lake. By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory, were begun that the Bells would name Beinn Bhreagh (Gaelic: Beautiful Mountain) after Bell's ancestral Scottish highlands. Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family. He was an enthusiastic boater, and Bell and his family sailed or rowed a long series of vessels on Bras d'Or Lake, ordering additional vessels from the H.W. Embree and Sons boatyard in Port Hawkesbury, Nova Scotia. In his final, and some of his most productive years, Bell split his residency between Washington, D.C., where he and his family initially resided for most of the year, and Beinn Bhreagh, where they spent increasing amounts of time. + +Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened. Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own". The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Mabel and Bell mobilized the community to help victims in Halifax. + +Later inventions + +Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. According to one of his biographers, Charlotte Gray, Bell's work ranged "unfettered across the scientific landscape" and he often went to bed voraciously reading the Encyclopædia Britannica, scouring it for new areas of interest. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels. + +Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive, and other magnetic media. + +Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses. + +Photophone + +Bell and his assistant Charles Sumner Tainter jointly invented a wireless telephone, named a photophone, which allowed for the transmission of both sounds and normal human conversations on a beam of light. Both men later became full associates in the Volta Laboratory Association. + +On June 21, 1880, Bell's assistant transmitted a wireless voice telephone message a considerable distance, from the roof of the Franklin School in Washington, D.C., to Bell at the window of his laboratory, some away, 19 years before the first voice radio transmissions. + +Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone". The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use. + +Metal detector + +Bell is also credited with developing one of the early versions of a metal detector through the use of an induction balance, after the shooting of U.S. President James A. Garfield in 1881. According to some accounts, the metal detector worked flawlessly in tests but did not find Guiteau's bullet, partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. Garfield's surgeons, led by self-appointed chief physician Doctor Willard Bliss, were skeptical of the device, and ignored Bell's requests to move the President to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus. + +Bell's own detailed account, presented to the American Association for the Advancement of Science in 1882, differs in several particulars from most of the many and varied versions now in circulation, by concluding that extraneous metal was not to blame for failure to locate the bullet. Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "proceeded to the Executive Mansion the next morning ... to ascertain from the surgeons whether they were perfectly sure that all metal had been removed from the neighborhood of the bed. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires. Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." In a footnote, Bell adds, "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus." + +Hydrofoils + +The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft. + +During his world tour of 1910–11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore. Baldwin described it as being as smooth as flying. On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag (Scottish Gaelic for 'little devil'), the first self-propelled Bell-Baldwin hydrofoil. The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. A top speed of was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia, to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boatbuilding enabled him to make useful design changes to the HD-4. After the First World War, work began again on the HD-4. Bell's report to the U.S. Navy permitted him to obtain two engines in July 1919. On September 9, 1919, the HD-4 set a world marine speed record of , a record which stood for ten years. + +Aeronautics + +In 1891, Bell had begun experiments to develop motor-powered heavier-than-air aircraft. The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of 60. + +In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk. The tetrahedral wings were named Cygnet I, II, and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 1907 to 1912. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site. + +Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. The AEA was headed by Bell and the founding members were four young men: American Glenn H. Curtiss, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York; and J. A. D. McCurdy–Baldwin and McCurdy being new engineering graduates from the University of Toronto. + +The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America. The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908. + +Their final aircraft design, the Silver Dart, embodied all of the advancements found in the earlier machines. On February 23, 1909, Bell was present as the Silver Dart flown by J. A. D. McCurdy from the frozen ice of Bras d'Or made the first aircraft flight in Canada. Bell had worried that the flight was too dangerous and had arranged for a doctor to be on hand. With the successful flight, the AEA disbanded and the Silver Dart would revert to Baldwin and McCurdy, who began the Canadian Aerodrome Company and would later demonstrate the aircraft to the Canadian Army. + +Heredity and genetics + +Bell, along with many members of the scientific community at the time, took an interest in the popular science of heredity which grew out of the publication of Charles Darwin's book On the Origin of Species in 1859. On his estate in Nova Scotia, Bell conducted meticulously recorded breeding experiments with rams and ewes. Over the course of more than 30 years, Bell sought to produce a breed of sheep with multiple nipples that would bear twins. He specifically wanted to see if selective breeding could produce sheep with four functional nipples with enough milk for twin lambs. This interest in animal breeding caught the attention of scientists focused on the study of heredity and genetics in humans. + +In November 1883, Bell presented a paper at a meeting of the National Academy of Sciences titled "Upon the Formation of a Deaf Variety of the Human Race". The paper is a compilation of data on the hereditary aspects of deafness. Bell's research indicated that a hereditary tendency toward deafness, as indicated by the possession of deaf relatives, was an important element in determining the production of deaf offspring. He noted that the proportion of deaf children born to deaf parents was many times greater than the proportion of deaf children born to the general population. In the paper, Bell delved into social commentary and discussed hypothetical public policies to bring an end to deafness. He also criticized educational practices that segregated deaf children rather than integrated them fulling into mainstream classrooms. The paper did not propose sterilization of deaf people or prohibition on intermarriage, noting that "We cannot dictate to men and women whom they should marry and natural selection no longer influences mankind to any great extent." + +A review of Bell's "Memoir upon the Formation of a Deaf Variety of the Human Race" appearing in an 1885 issue of the "American Annals of the Deaf and Dumb" states that "Dr. Bell does not advocate legislative interference with the marriages of the deaf for several reasons one of which is that the results of such marriages have not yet been sufficiently investigated." The article goes on to say that "the editorial remarks based thereon did injustice to the author." The paper's author concludes by saying "A wiser way to prevent the extension of hereditary deafness, it seems to us, would be to continue the investigations which Dr. Bell has so admirable begun until the laws of the transmission of the tendency to deafness are fully understood, and then by explaining those laws to the pupils of our schools to lead them to choose their partners in marriage in such a way that deaf-mute offspring will not be the result." + +Historians have noted that Bell explicitly opposed laws regulating marriage, and never mentioned sterilization in any of his writings. Even after Bell agreed to engage with scientists conducting eugenic research, he consistently refused to support public policy that limited the rights or privileges of the deaf. + +Bell's interest and research on heredity attracted the interest of Charles Davenport, a Harvard professor and head of the Cold Spring Harbor Laboratory. In 1906, Davenport, who was also the founder of the American Breeder's Association, approached Bell about joining a new committee on eugenics chaired by David Starr Jordan. In 1910, Davenport opened the Eugenics Records office at Cold Spring Harbor. To give the organization scientific credibility, Davenport set up a Board of Scientific Directors naming Bell as chairman. Other members of the board included Luther Burbank, Roswell H. Johnson, Vernon L. Kellogg, and William E. Castle. + +In 1921, a Second International Congress of Eugenics was held in New York at the Museum of Natural History and chaired by Davenport. Although Bell did not present any research or speak as part of the proceedings, he was named as honorary president as a means to attract other scientists to attend the event. A summary of the event notes that Bell was a "pioneering investigator in the field of human heredity". + +Death +Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75. Bell had also been affected by pernicious anemia. His last view of the land he had inhabited was by moonlight on his mountain estate at 2:00 a.m. While tending to him after his long illness, Mabel, his wife, whispered, "Don't leave me." By way of reply, Bell signed "no...", lost consciousness, and died shortly after. + +On learning of Bell's death, the Canadian Prime Minister, Mackenzie King, cabled Mrs. Bell, saying: + +Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments. To help celebrate his life, his wife asked guests not to wear black (the traditional funeral color) while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson's "Requiem": + +Upon the conclusion of Bell's funeral, for one minute at 6:25 p.m. Eastern Time, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance". + +Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake. He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren. + +Legacy and honors + +Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew. Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. During his life, he also received dozens of major awards, medals, and other tributes. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford, Ontario, in 1917. + +A large number of Bell's writings, personal correspondence, notebooks, papers, and other documents reside in both the United States Library of Congress Manuscript Division (as the Alexander Graham Bell Family Papers), and at the Alexander Graham Bell Institute, Cape Breton University, Nova Scotia; major portions of which are available for online viewing. + +A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada. Among the major sites are: + The Alexander Graham Bell National Historic Site, maintained by Parks Canada, which incorporates the Alexander Graham Bell Museum, in Baddeck, Nova Scotia, close to the Bell estate Beinn Bhreagh + The Bell Homestead National Historic Site, includes the Bell family home, "Melville House", and farm overlooking Brantford, Ontario and the Grand River. It was their first home in North America; + Canada's first telephone company building, the "Henderson Home" of the late 1870s, a predecessor of the Bell Telephone Company of Canada (officially chartered in 1880). In 1969, the building was carefully moved to the historic Bell Homestead National Historic Site in Brantford, Ontario, and was refurbished to become a telephone museum. The Bell Homestead, the Henderson Home telephone museum, and the National Historic Site's reception centre are all maintained by the Bell Homestead Society; + The Alexander Graham Bell Memorial Park, which features a broad neoclassical monument built in 1917 by public subscription. The monument depicts mankind's ability to span the globe through telecommunications; + The Alexander Graham Bell Museum (opened in 1956), part of the Alexander Graham Bell National Historic Site which was completed in 1978 in Baddeck, Nova Scotia. Many of the museum's artifacts were donated by Bell's daughters; + +In 1880, Bell received the Volta Prize with a purse of 50,000 French francs (approximately US$ in today's dollars) for the invention of the telephone from the French government. Among the luminaries who judged were Victor Hugo and Alexandre Dumas, fils. The Volta Prize was conceived by Napoleon III in 1852, and named in honor of Alessandro Volta, with Bell becoming the second recipient of the grand prize in its history. Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness. + +In partnership with Gardiner Greene Hubbard, Bell helped establish the publication Science during the early 1880s. In 1898, Bell was elected as the second president of the National Geographic Society, serving until 1903, and was primarily responsible for the extensive use of illustrations, including photography, in the magazine. He also served for many years as a Regent of the Smithsonian Institution (1898–1922). The French government conferred on him the decoration of the Légion d'honneur (Legion of Honor); the Royal Society of Arts in London awarded him the Albert Medal in 1902; the University of Würzburg, Bavaria, granted him a PhD, and he was awarded the Franklin Institute's Elliott Cresson Medal in 1912. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891 to 1892. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone". + +The bel (B) and the smaller decibel (dB) are units of measurement of sound pressure level (SPL) invented by Bell Labs and named after him. Since 1976, the IEEE's Alexander Graham Bell Medal has been awarded to honor outstanding contributions in the field of telecommunications. + +In 1936, the US Patent Office declared Bell first on its list of the country's greatest inventors, leading to the US Post Office issuing a commemorative stamp honoring Bell in 1940 as part of its 'Famous Americans Series'. The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf. The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series. + +The 150th anniversary of Bell's birth in 1997 was marked by a special issue of commemorative £1 banknotes from the Royal Bank of Scotland. The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics. Additionally, the Government of Canada honored Bell in 1997 with a C$100 gold coin, in tribute also to the 150th anniversary of his birth, and with a silver dollar coin in 2009 in honor of the 100th anniversary of flight in Canada. That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. Bell's image, and also those of his many inventions have graced paper money, coinage, and postal stamps in numerous countries worldwide for many dozens of years. + +Alexander Graham Bell was ranked 57th among the 100 Greatest Britons (2002) in an official BBC nationwide poll, and among the Top Ten Greatest Canadians (2004), and the 100 Greatest Americans (2005). In 2006, Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. Bell's name is still widely known and used as part of the names of dozens of educational institutes, corporate namesakes, street and place names around the world. + +Honorary degrees + +Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.D.s (Doctorate of Laws), two Ph.D.s, a D.Sc., and an M.D.: + Gallaudet College (then named National Deaf-Mute College) in Washington, D.C.

The land mass of Anatolia constitutes most of the territory of contemporary Turkey. Geographically, the Anatolian region is bounded by the Turkish Straits to the north-west, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus strait and the Dardanelles strait, and separates Anatolia from Thrace in the Balkan peninsula of Southeastern Europe. + +The eastern border of Anatolia is a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the south-east, thus Anatolia comprises approximately the western two-thirds of the Asian territory of Turkey. Anatolia sometimes is synonymous with Asian Turkey, thereby including the western part of the Armenian Highlands and northern Mesopotamia and making its eastern and southern borders coterminous with Turkey's borders. + +The ancient Anatolian peoples spoke the now-extinct Anatolian languages of the Indo-European language family, which were largely replaced by the Greek language during classical antiquity as well as during the Hellenistic, Roman, and Byzantine periods. The major Anatolian languages included Hittite, Luwian, and Lydian, while other, poorly attested local languages included Phrygian and Mysian. Hurro-Urartian languages were spoken in the southeastern kingdom of Mitanni, while Galatian, a Celtic language, was spoken in Galatia, central Anatolia. Ancient peoples in the region included Galatians, Hurrians, Assyrians, Hattians, Cimmerians, as well as Ionian, Dorian, and Aeolic Greeks. The Turkification of Anatolia began under the rule of the Seljuk Empire in the late 11th century, continued under the Ottoman Empire between the late 13th and early 20th centuries, and continues today under the Republic of Turkey. However, various non-Turkic languages continue to be spoken by minorities in Anatolia, including Kurdish, Neo-Aramaic, Armenian, North Caucasian languages, Laz, Georgian, and Greek. + +Geography + +Traditionally, Anatolia is considered to extend in the east to an indefinite line running from the Gulf of Alexandretta to the Black Sea, coterminous with the Anatolian Plateau. This traditional geographical definition is used, for example, in the latest edition of Merriam-Webster's Geographical Dictionary. Under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria and the Mesopotamian plain. + +Following the Armenian genocide, Western Armenia was renamed the Eastern Anatolia Region by the newly established Turkish government. In 1941, with the First Geography Congress which divided Turkey into seven geographical regions based on differences in climate and landscape, the eastern provinces of Turkey were placed into the Eastern Anatolia Region, which largely corresponds to the historical region of Western Armenia (named as such after the division of Greater Armenia between the Roman/Byzantine Empire (Western Armenia) and Sassanid Persia (Eastern Armenia) in 387 AD). Vazken Davidian terms the expanded use of "Anatolia" to apply to territory in eastern Turkey that was formerly referred to as Armenia (which had a sizeable Armenian population before the Armenian genocide) an "ahistorical imposition" and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia". + +The highest mountain in the Eastern Anatolia Region (also the highest peak in the Armenian Highlands) is Mount Ararat (5123 m). The Euphrates, Aras, Karasu and Murat rivers connect the Armenian Highlands to the South Caucasus and the Upper Euphrates Valley. Along with the Çoruh, these rivers are the longest in the Eastern Anatolia Region. + +Etymology +The English-language name Anatolia derives from the Greek () meaning "the East" and designating (from a Greek point of view) eastern regions in general. The Greek word refers to the direction where the sun rises, coming from anatello '(Ι) rise up', comparable to terms in other languages such as "levant" from Latin 'to rise', "orient" from Latin 'to arise, to originate', Hebrew mizraḥ 'east' from zaraḥ 'to rise, to shine', Aramaic midnaḥ from denaḥ 'to rise, to shine'. + +The use of Anatolian designations has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies situated along the eastern coasts of the Aegean Sea, but also encompassing eastern regions in general. Such use of Anatolian designations was employed during the reign of Roman Emperor Diocletian (), who created the Diocese of the East, known in Greek as the Eastern Diocese, but completely unrelated to the regions of Asia Minor. In their widest territorial scope, Anatolian designations were employed during the reign of Roman Emperor Constantine I (306–337), who created the Praetorian prefecture of the East, known in Greek as the Eastern Prefecture, encompassing all eastern regions of the Late Roman Empire and spanning from Thrace to Egypt. + +Only after the loss of other eastern regions during the 7th century and the reduction of Byzantine eastern domains to Asia Minor, that region became the only remaining part of the Byzantine East, and thus commonly referred to (in Greek) as the Eastern part of the Empire. At the same time, the Anatolic Theme ( / "the Eastern theme") was created, as a province (theme) covering the western and central parts of Turkey's present-day Central Anatolia Region, centered around Iconium, but ruled from the city of Amorium. + +The Latinized form "", with its -ia ending, is probably a Medieval Latin innovation. The modern Turkish form derives directly from the Greek name (Anatolḗ). The Russian male name Anatoly, the French Anatole and plain Anatol, all stemming from saints Anatolius of Laodicea (d. 283) and Anatolius of Constantinople (d. 458; the first Patriarch of Constantinople), share the same linguistic origin. + +Names + +The oldest known name for any region within Anatolia is related to its central area, known as the "Land of Hatti" – a designation that was initially used for the land of ancient Hattians, but later became the most common name for the entire territory under the rule of ancient Hittites. + +The first recorded name the Greeks used for the Anatolian peninsula, though not particularly popular at the time, was Ἀσία (Asía), perhaps from an Akkadian expression for the "sunrise" or possibly echoing the name of the Assuwa league in western Anatolia. The Romans used it as the name of their province, comprising the west of the peninsula plus the nearby Aegean Islands. As the name "Asia" broadened its scope to apply to the vaster region east of the Mediterranean, some Greeks in Late Antiquity came to use the name Asia Minor (Μικρὰ Ἀσία, Mikrà Asía), meaning "Lesser Asia" to refer to present-day Anatolia, whereas the administration of the Empire preferred the description Ἀνατολή (Anatolḗ; ). + +The endonym Ῥωμανία (Rōmanía "the land of the Romans, i.e. the Eastern Roman Empire") was understood as another name for the province by the invading Seljuq Turks, who founded a Sultanate of Rûm in 1077. Thus (land of the) Rûm became another name for Anatolia. By the 12th century Europeans had started referring to Anatolia as Turchia. + +During the era of the Ottoman Empire, mapmakers outside the Empire referred to the mountainous plateau in eastern Anatolia as Armenia. Other contemporary sources called the same area Kurdistan. Geographers have variously used the terms East Anatolian Plateau and Armenian Plateau to refer to the region, although the territory encompassed by each term largely overlaps with the other. According to archaeologist Lori Khatchadourian, this difference in terminology "primarily result[s] from the shifting political fortunes and cultural trajectories of the region since the nineteenth century". + +Turkey's First Geography Congress in 1941 created two geographical regions of Turkey to the east of the Gulf of Iskenderun-Black Sea line, the Eastern Anatolia Region and the Southeastern Anatolia Region, the former largely corresponding to the western part of the Armenian Highlands, the latter to the northern part of the Mesopotamian plain. According to Richard Hovannisian, this changing of toponyms was "necessary to obscure all evidence" of the Armenian presence as part of the policy of Armenian genocide denial embarked upon by the newly established Turkish government and what Hovannisian calls its "foreign collaborators". + +History + +Prehistoric Anatolia + +Human habitation in Anatolia dates back to the Paleolithic. Neolithic settlements include Çatalhöyük, Çayönü, Nevali Cori, Aşıklı Höyük, Boncuklu Höyük, Hacilar, Göbekli Tepe, Norşuntepe, Köşk Höyük, and Yumuktepe. Çatalhöyük (7.000 BCE) is considered the most advanced of these. Neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the earliest attested branch of Indo-European, have been spoken in Anatolia since at least the 19th century BCE. + +Recent advances in archaeogenetics have confirmed that the spread of agriculture from the Middle East to Europe was strongly correlated with the migration of early farmers from Anatolia about 9,000 years ago, and was not just a cultural exchange. Anatolian Neolithic farmers derived a significant portion of their ancestry from the Anatolian hunter-gatherers, suggesting that agriculture was adopted in site by these hunter-gatherers and not spread by demic diffusion into the region. + +Ancient Anatolia + +The earliest historical data related to Anatolia appear during the Bronze Age and continue throughout the Iron Age. The most ancient period in the history of Anatolia spans from the emergence of ancient Hattians, up to the conquest of Anatolia by the Achaemenid Empire in the 6th century BCE. + +Hattians and Hurrians + +The earliest historically attested populations of Anatolia were the Hattians in central Anatolia, and Hurrians further to the east. The Hattians were an indigenous people, whose main center was the city of Hattush. Affiliation of Hattian language remains unclear, while Hurrian language belongs to a distinctive family of Hurro-Urartian languages. All of those languages are extinct; relationships with indigenous languages of the Caucasus have been proposed, but are not generally accepted. The region became famous for exporting raw materials. Organized trade between Anatolia and Mesopotamia started to emerge during the period of the Akkadian Empire, and was continued and intensified during the period of the Old Assyrian Empire, between the 21st and the 18th centuries BCE. Assyrian traders were bringing tin and textiles in exchange for copper, silver or gold. Cuneiform records, dated , found in Anatolia at the Assyrian colony of Kanesh, use an advanced system of trading computations and credit lines. + +Hittite Anatolia (18th–12th century BCE) + +Unlike the Akkadians and Assyrians, whose Anatolian trading posts were peripheral to their core lands in Mesopotamia, the Hittites were centered at Hattusa (modern Boğazkale) in north-central Anatolia by the 17th century BCE. They were speakers of an Indo-European language, the Hittite language, or nesili (the language of Nesa) in Hittite. The Hittites originated from local ancient cultures that grew in Anatolia, in addition to the arrival of Indo-European languages. Attested for the first time in the Assyrian tablets of Nesa around 2000 BCE, they conquered Hattusa in the 18th century BCE, imposing themselves over Hattian- and Hurrian-speaking populations. According to the widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites (along with the other Indo-European ancient Anatolians) were themselves relatively recent immigrants to Anatolia from the north. However, they did not necessarily displace the population genetically; they assimilated into the former peoples' culture, preserving the Hittite language. + +The Hittites adopted the Mesopotamian cuneiform script. In the Late Bronze Age, Hittite New Kingdom () was founded, becoming an empire in the 14th century BCE after the conquest of Kizzuwatna in the south-east and the defeat of the Assuwa league in western Anatolia. The empire reached its height in the 13th century BCE, controlling much of Asia Minor, northwestern Syria, and northwest upper Mesopotamia. However, the Hittite advance toward the Black Sea coast was halted by the semi-nomadic pastoralist and tribal Kaskians, a non-Indo-European people who had earlier displaced the Palaic-speaking Indo-Europeans. Much of the history of the Hittite Empire concerned war with the rival empires of Egypt, Assyria and the Mitanni. + +The Ancient Egyptians eventually withdrew from the region after failing to gain the upper hand over the Hittites and becoming wary of the power of Assyria, which had destroyed the Mitanni Empire. The Assyrians and Hittites were then left to battle over control of eastern and southern Anatolia and colonial territories in Syria. The Assyrians had better success than the Egyptians, annexing much Hittite (and Hurrian) territory in these regions. + +Post-Hittite Anatolia (12th–6th century BCE) + +After 1180 BCE, during the Late Bronze Age collapse, the Hittite Empire disintegrated into several independent Syro-Hittite states, subsequent to losing much territory to the Middle Assyrian Empire and being finally overrun by the Phrygians, another Indo-European people who are believed to have migrated from the Balkans. The Phrygian expansion into southeast Anatolia was eventually halted by the Assyrians, who controlled that region. + +Luwians +Another Indo-European people, the Luwians, rose to prominence in central and western Anatolia BCE. Their language belonged to the same linguistic branch as Hittite. The general consensus amongst scholars is that Luwian was spoken across a large area of western Anatolia, including (possibly) Wilusa (Troy), the Seha River Land (to be identified with the Hermos and/or Kaikos valley), and the kingdom of Mira-Kuwaliya with its core territory of the Maeander valley. From the 9th century BCE, Luwian regions coalesced into a number of states such as Lydia, Caria, and Lycia, all of which had Hellenic influence. + +Arameans +Arameans encroached over the borders of south-central Anatolia in the century or so after the fall of the Hittite empire, and some of the Syro-Hittite states in this region became an amalgam of Hittites and Arameans. These became known as Syro-Hittite states. + +Neo-Assyrian Empire + +From the 10th to late 7th centuries BCE, much of Anatolia (particularly the southeastern regions) fell to the Neo-Assyrian Empire, including all of the Syro-Hittite states, Tabal, Commagene, the Cimmerians and Scythians, and swathes of Cappadocia. + +The Neo-Assyrian empire collapsed due to a bitter series of civil wars followed by a combined attack by Medes, Persians, Scythians and their own Babylonian relations. The last Assyrian city to fall was Harran in southeast Anatolia. This city was the birthplace of the last king of Babylon, the Assyrian Nabonidus and his son and regent Belshazzar. Much of the region then fell to the short-lived Iran-based Median Empire, with the Babylonians and Scythians briefly appropriating some territory. + +Cimmerian and Scythian invasions +From the late 8th century BCE, a new wave of Indo-European-speaking raiders entered northern and northeast Anatolia: the Cimmerians and Scythians. The Cimmerians overran Phrygia and the Scythians threatened to do the same to Urartu and Lydia, before both were finally checked by the Assyrians. + +Early Greek presence + +The north-western coast of Anatolia was inhabited by Greeks of the Achaean/Mycenaean culture from the 20th century BCE, related to the Greeks of southeastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BCE, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). + +Classical Anatolia + +In Classical antiquity, Anatolia was described by the Ancient Greek historian Herodotus and later historians as divided into regions that were diverse in culture, language, and religious practices. The northern regions included Bithynia, Paphlagonia, and Pontus; to the west were Mysia, Lydia, and Caria; and Lycia, Pamphylia, and Cilicia belonged to the southern shore. There were also several inland regions: Phrygia, Cappadocia, Pisidia, and Galatia. Languages spoken included the late surviving Anatolic languages, Isaurian, and Pisidian, Greek in western and coastal regions, Phrygian spoken until the 7th century CE, local variants of Thracian in the northwest, the Galatian variant of Gaulish in Galatia until the 6th century CE, Cappadocian in the homonymous region, Armenian in the east, and Kartvelian languages in the northeast. + +Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BCE in Lydia. The use of minted coins continued to flourish during the Greek and Roman eras. + +During the 6th century BCE, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty of Persia. In 499 BCE, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BCE, and the Ionian cities regained their independence. By the Peace of Antalcidas (387 BCE), which ended the Corinthian War, Persia regained control over Ionia. + +In 334 BCE, the Macedonian Greek king Alexander the Great conquered the Anatolian peninsula from the Achaemenid Persian Empire. Alexander's conquest opened up the interior of Asia Minor to Greek settlement and influence. + Following the death of Alexander the Great and the subsequent breakup of the Macedonian Empire, Anatolia was ruled by a series of Hellenistic kingdoms, such as the Attalids of Pergamum and the Seleucids, the latter controlling most of Anatolia. A period of peaceful Hellenization followed, such that the local Anatolian languages had been supplanted by Greek by the 1st century BCE. In 133 BCE the last Attalid king bequeathed his kingdom to the Roman Republic; western and central Anatolia came under Roman control, but Hellenistic culture remained predominant. + +Mithridates VI Eupator, ruler of the Kingdom of Pontus in northern Anatolia, waged war against the Roman Republic in the year 88 BCE in order to halt the advance of Roman hegemony in the Aegean Sea region. Mithridates VI sought to dominate Asia Minor and the Black Sea region, waging several hard-fought but ultimately unsuccessful wars (the Mithridatic Wars) to break Roman dominion over Asia and the Hellenic world. He has been called the greatest ruler of the Kingdom of Pontus. Further annexations by Rome, in particular of the Kingdom of Pontus by Pompey, brought all of Anatolia under Roman control, except for the southeastern frontier with the Parthian Empire, which remained unstable for centuries, causing a series of military conflicts that culminated in the Roman–Parthian Wars (54 BCE – 217 CE). + +Early Christian Period + +After the first division of the Roman Empire, Anatolia became part of the Eastern Roman Empire, otherwise known as the Byzantine Empire or Byzantium. In the 1st century CE, Anatolia became one of the first places where Christianity spread, so that by the 4th century CE, western and central Anatolia were overwhelmingly Christian and Greek-speaking. + +Byzantine Anatolia was one of the wealthiest and most densely populated places in the Later Roman Empire. Anatolia's wealth grew during the 4th and 5th centuries thanks, in part, to the Pilgrim's Road that ran through the peninsula. Literary evidence about the rural landscape stems from the Christian hagiographies of the 6th-century Nicholas of Sion and 7th-century Theodore of Sykeon. Large and prosperous urban centers of Byzantine Anatolia included Assos, Ephesus, Miletus, Nicaea, Pergamum, Priene, Sardis, and Aphrodisias. + +From the mid-5th century onwards, urbanism was affected negatively and began to decline, while the rural areas reached unprecedented levels of prosperity in the region. Historians and scholars continue to debate the cause of the urban decline in Byzantine Anatolia between the 6th and 7th centuries, variously attributing it to the Plague of Justinian (541), the Byzantine–Sasanian War (602–628), and the Arab invasion of the Levant (634–638). + +Medieval Period + +In the 10 years following the Battle of Manzikert in 1071, the Seljuk Turks from Central Asia migrated over large areas of Anatolia, with particular concentrations around the northwestern rim. The Turkish language and the Islamic religion were gradually introduced as a result of the Seljuk conquest, and this period marks the start of Anatolia's slow transition from predominantly Christian and Greek-speaking, to predominantly Muslim and Turkish-speaking (although ethnic groups such as Armenians, Greeks, and Assyrians remained numerous and retained Christianity and their native languages). In the following century, the Byzantines managed to reassert their control in western and northern Anatolia. Control of Anatolia was then split between the Byzantine Empire and the Seljuk Sultanate of Rûm, with the Byzantine holdings gradually being reduced. + +In 1255, the Mongols swept through eastern and central Anatolia, and would remain until 1335. The Ilkhanate garrison was stationed near Ankara. After the decline of the Ilkhanate from 1335 to 1353, the Mongol Empire's legacy in the region was the Uyghur Eretna Dynasty that was overthrown by Kadi Burhan al-Din in 1381. + +By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks. Smyrna fell in 1330, and the last Byzantine stronghold in Anatolia, Philadelphia, fell in 1390. The Turkmen Beyliks were under the control of the Mongols, at least nominally, through declining Seljuk sultans. The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids. The Osmanli ruler Osman I was the first Turkish ruler who minted coins in his own name in 1320s; they bear the legend "Minted by Osman son of Ertugrul". Since the minting of coins was a prerogative accorded in Islamic practice only to a sovereign, it can be considered that the Osmanli, or Ottoman Turks, had become formally independent from the Mongol Khans. + +Ottoman Empire + +Among the Turkish leaders, the Ottomans emerged as great power under Osman I and his son Orhan. The Anatolian beyliks were successively absorbed into the rising Ottoman Empire during the 15th century. It is not well understood how the Osmanlı, or Ottoman Turks, came to dominate their neighbours, as the history of medieval Anatolia is still little known. The Ottomans completed the conquest of the peninsula in 1517 with the taking of Halicarnassus (modern Bodrum) from the Knights of Saint John. + +Modern times + +With the acceleration of the decline of the Ottoman Empire in the early 19th century, and as a result of the expansionist policies of the Russian Empire in the Caucasus, many Muslim nations and groups in that region, mainly Circassians, Tatars, Azeris, Lezgis, Chechens and several Turkic groups left their homelands and settled in Anatolia. As the Ottoman Empire further shrank in the Balkan regions and then fragmented during the Balkan Wars, much of the non-Christian populations of its former possessions, mainly Balkan Muslims (Bosniaks, Albanians, Turks, Muslim Bulgarians and Greek Muslims such as the Vallahades from Greek Macedonia), were resettled in various parts of Anatolia, mostly in formerly Christian villages throughout Anatolia. + +A continuous reverse migration occurred since the early 19th century, when Greeks from Anatolia, Constantinople and Pontus area migrated toward the newly independent Kingdom of Greece, and also towards the United States, the southern part of the Russian Empire, Latin America, and the rest of Europe. + +Following the Russo-Persian Treaty of Turkmenchay (1828) and the incorporation of Eastern Armenia into the Russian Empire, another migration involved the large Armenian population of Anatolia, which recorded significant migration rates from Western Armenia (Eastern Anatolia) toward the Russian Empire, especially toward its newly established Armenian provinces. + +Anatolia remained multi-ethnic until the early 20th century (see the rise of nationalism under the Ottoman Empire). During World War I, the Armenian genocide, the Greek genocide (especially in Pontus), and the Assyrian genocide almost entirely removed the ancient indigenous communities of Armenian, Greek, and Assyrian populations in Anatolia and surrounding regions. Following the Greco-Turkish War of 1919–1922, most remaining ethnic Anatolian Greeks were forced out during the 1923 population exchange between Greece and Turkey. Of the remainder, most have left Turkey since then, leaving fewer than 5,000 Greeks in Anatolia today. + +Geology + +Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east. True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and the Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin (Konya Ovasi). + +There are two mountain ranges in southern Anatolia: the Taurus and the Zagros mountains. + +Climate + +Anatolia has a varied range of climates. The central plateau is characterized by a continental climate, with hot summers and cold snowy winters. The south and west coasts enjoy a typical Mediterranean climate, with mild rainy winters, and warm dry summers. The Black Sea and Marmara coasts have a temperate oceanic climate, with cool foggy summers and much rainfall throughout the year. + +Ecoregions + +There is a diverse number of plant and animal communities. + +The mountains and coastal plain of northern Anatolia experience a humid and mild climate. There are temperate broadleaf, mixed and coniferous forests. The central and eastern plateau, with its drier continental climate, has deciduous forests and forest steppes. Western and southern Anatolia, which have a Mediterranean climate, contain Mediterranean forests, woodlands, and scrub ecoregions. + Euxine-Colchic deciduous forests: These temperate broadleaf and mixed forests extend across northern Anatolia, lying between the mountains of northern Anatolia and the Black Sea. They include the enclaves of temperate rainforest lying along the southeastern coast of the Black Sea in eastern Turkey and Georgia. + Northern Anatolian conifer and deciduous forests: These forests occupy the mountains of northern Anatolia, running east and west between the coastal Euxine-Colchic forests and the drier, continental climate forests of central and eastern Anatolia. + Central Anatolian deciduous forests: These forests of deciduous oaks and evergreen pines cover the plateau of central Anatolia. + Central Anatolian steppe: These dry grasslands cover the drier valleys and surround the saline lakes of central Anatolia, and include halophytic (salt tolerant) plant communities. + + Eastern Anatolian deciduous forests: This ecoregion occupies the plateau of eastern Anatolia. The drier and more continental climate is beneficial for steppe-forests dominated by deciduous oaks, with areas of shrubland, montane forest, and valley forest. + Anatolian conifer and deciduous mixed forests: These forests occupy the western, Mediterranean-climate portion of the Anatolian plateau. Pine forests and mixed pine and oak woodlands and shrublands are predominant. + Aegean and Western Turkey sclerophyllous and mixed forests: These Mediterranean-climate forests occupy the coastal lowlands and valleys of western Anatolia bordering the Aegean Sea. The ecoregion has forests of Turkish pine (Pinus brutia), oak forests and woodlands, and maquis shrubland of Turkish pine and evergreen sclerophyllous trees and shrubs, including Olive (Olea europaea), Strawberry Tree (Arbutus unedo), Arbutus andrachne, Kermes Oak (Quercus coccifera), and Bay Laurel (Laurus nobilis). + Southern Anatolian montane conifer and deciduous forests: These mountain forests occupy the Mediterranean-climate Taurus Mountains of southern Anatolia. Conifer forests are predominant, chiefly Anatolian black pine (Pinus nigra), Cedar of Lebanon (Cedrus libani), Taurus fir (Abies cilicica), and juniper (Juniperus foetidissima and J. excelsa). Broadleaf trees include oaks, hornbeam, and maples. + Eastern Mediterranean conifer-sclerophyllous-broadleaf forests: This ecoregion occupies the coastal strip of southern Anatolia between the Taurus Mountains and the Mediterranean Sea. Plant communities include broadleaf sclerophyllous maquis shrublands, forests of Aleppo Pine (Pinus halepensis) and Turkish Pine (Pinus brutia), and dry oak (Quercus spp.) woodlands and steppes. + +Demographics + +The largest cities in Anatolia (aside from the Asian side of Istanbul) are Ankara, İzmir, Bursa, Antalya, Konya, Adana, İzmit, Mersin, Manisa, Kayseri, Samsun, Balıkesir, Kahramanmaraş, Aydın, Adapazarı, Denizli, Muğla, Eskişehir, Trabzon, Ordu, Afyonkarahisar, Sivas, Tokat, Zonguldak, Kütahya, Çanakkale, Osmaniye, Şırnak and Çorum.

It is considered one of the Big Five American information technology companies, alongside Alphabet (parent company of Google), Amazon, Meta Platforms, and Microsoft. + +Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977. The company's second computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interfaces, including the 1984 original Macintosh, announced that year in a critically acclaimed advertisement called "1984". By 1985, the high cost of its products, and power struggles between executives, caused problems. Wozniak stepped back from Apple and pursued other ventures, while Jobs resigned and founded NeXT, taking some Apple employees with him. + +As the market for personal computers expanded and evolved throughout the 1990s, Apple lost considerable market share to the lower-priced duopoly of the Microsoft Windows operating system on Intel-powered PC clones (also known as "Wintel"). In 1997, weeks away from bankruptcy, the company bought NeXT to resolve Apple's unsuccessful operating system strategy and entice Jobs back to the company. Over the next decade, Jobs guided Apple back to profitability through a number of tactics including introducing the iMac, iPod, iPhone and iPad to critical acclaim, launching the "Think different" campaign and other memorable advertising campaigns, opening the Apple Store retail chain, and acquiring numerous companies to broaden the company's product portfolio. When Jobs resigned in 2011 for health reasons, and died two months later, he was succeeded as CEO by Tim Cook. + +Apple became the first publicly traded U.S. company to be valued at over $1 trillion in August 2018, then at $2 trillion in August 2020, and at $3 trillion in January 2022. In June 2023, it was valued at just over $3 trillion. The company receives criticism regarding the labor practices of its contractors, its environmental practices, and its business ethics, including anti-competitive practices and materials sourcing. Nevertheless, the company has a large following and enjoys a high level of brand loyalty. It has also been consistently ranked as one of the world's most valuable brands. + +History + +1976–1980: Founding and incorporation + +Apple Computer Company was founded on April 1, 1976, by Steve Jobs, Steve Wozniak, and Ronald Wayne as a partnership. The company's first product was the Apple I, a computer designed and hand-built entirely by Wozniak. To finance its creation, Jobs sold his Volkswagen Bus, and Wozniak sold his HP-65 calculator. Wozniak debuted the first prototype Apple I at the Homebrew Computer Club in July 1976. The Apple I was sold as a motherboard with CPU, RAM, and basic textual-video chips—a base kit concept which would not yet be marketed as a complete personal computer. It went on sale soon after debut for . Wozniak later said he was unaware of the coincidental mark of the beast in the number 666, and that he came up with the price because he liked "repeating digits". + +Apple Computer, Inc. was incorporated on January 3, 1977, without Wayne, who had left and sold his share of the company back to Jobs and Wozniak for $800 only twelve days after having co-founded Apple. Multimillionaire Mike Markkula provided essential business expertise and funding of to Jobs and Wozniak during the incorporation of Apple. During the first five years of operations, revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980, yearly sales grew from $775,000 to $118 million, an average annual growth rate of 533%. + +The Apple II, also invented by Wozniak, was introduced on April 16, 1977, at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics and open architecture. While the Apple I and early Apple II models used ordinary audio cassette tapes as storage devices, they were superseded by the introduction of a -inch floppy disk drive and interface called the Disk II in 1978. + +The Apple II was chosen to be the desktop platform for the first "killer application" of the business world: VisiCalc, a spreadsheet program released in 1979. VisiCalc created a business market for the Apple II and gave home users an additional reason to buy an Apple II: compatibility with the office, but Apple II market share remained behind home computers made by competitors such as Atari, Commodore, and Tandy. + +On December 12, 1980, Apple (ticker symbol "AAPL") went public selling 4.6 million shares at $22 per share ($.10 per share when adjusting for stock splits ), generating over $100 million, which was more capital than any IPO since Ford Motor Company in 1956. By the end of the day, 300 millionaires were created, from a stock price of $29 per share and a market cap of $1.778 billion. + +1980–1990: Success with Macintosh + +A critical moment in the company's history came in December 1979 when Jobs and several Apple employees, including human–computer interface expert Jef Raskin, visited Xerox PARC in to see a demonstration of the Xerox Alto, a computer using a graphical user interface. Xerox granted Apple engineers three days of access to the PARC facilities in return for the option to buy 100,000 shares (22.4 million split-adjusted shares ) of Apple at the pre-IPO price of $10 a share. After the demonstration, Jobs was immediately convinced that all future computers would use a graphical user interface, and development of a GUI began for the Apple Lisa, named after Jobs's daughter. + +The Lisa division would be plagued by infighting, and in 1982 Jobs was pushed off the project. The Lisa launched in 1983 and became the first personal computer sold to the public with a GUI, but was a commercial failure due to its high price and limited software titles. + +Jobs, angered by being pushed off the Lisa team, took over the company's Macintosh division. Wozniak and Raskin had envisioned the Macintosh as a low-cost computer with a text-based interface like the Apple II, but a plane crash in 1981 forced Wozniak to step back from the project. Jobs quickly redefined the Macintosh as a graphical system that would be cheaper than the Lisa, undercutting his former division. Jobs was also hostile to the Apple II division, which at the time, generated most of the company's revenue. + +In 1984, Apple launched the Macintosh, the first personal computer to be sold without a programming language. Its debut was signified by "1984", a $1.5 million television advertisement directed by Ridley Scott that aired during the third quarter of Super Bowl XVIII on January 22, 1984. This is now hailed as a watershed event for Apple's success and was called a "masterpiece" by CNN and one of the greatest TV advertisements of all time by TV Guide. + +The advertisement created great interest in the original Macintosh, and sales were initially good, but began to taper off dramatically after the first three months as reviews started to come in. Jobs had made the decision to equip the original Macintosh with 128 kilobytes of RAM, attempting to reach a price point, which limited its speed and the software that could be used. The Macintosh would eventually ship for , a price panned by critics in light of its slow performance. In early 1985, this sales slump triggered a power struggle between Steve Jobs and CEO John Sculley, who had been hired away from Pepsi two years earlier by Jobs saying, "Do you want to sell sugar water for the rest of your life or come with me and change the world?" Sculley decided to remove Jobs as the head of the Macintosh division, with unanimous support from the Apple board of directors. + +The board of directors instructed Sculley to contain Jobs and his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from his leadership role at Apple. Informed by Jean-Louis Gassée, Sculley found out that Jobs had been attempting to organize a boardroom coup and called an emergency meeting at which Apple's executive staff sided with Sculley and stripped Jobs of all operational duties. Jobs resigned from Apple in September 1985 and took a number of Apple employees with him to found NeXT. Wozniak had also quit his active employment at Apple earlier in 1985 to pursue other ventures, expressing his frustration with Apple's treatment of the Apple II division and stating that the company had "been going in the wrong direction for the last five years." Despite Wozniak's grievances, he officially remained employed by Apple, and to this day continues to work for the company as a representative, receiving a stipend estimated to be $120,000 per year for this role. Both Jobs and Wozniak remained Apple shareholders after their departures. + +After the departures of Jobs and Wozniak, Sculley worked to improve the Macintosh in 1985 by quadrupling the RAM and introducing the LaserWriter, the first reasonably priced PostScript laser printer. PageMaker, an early desktop publishing application taking advantage of the PostScript language, was also released by Aldus Corporation in July 1985. It has been suggested that the combination of Macintosh, LaserWriter and PageMaker was responsible for the creation of the desktop publishing market. + +This dominant position in the desktop publishing market allowed the company to focus on higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Newer models selling at higher price points offered higher profit margin, and appeared to have no effect on total sales as power users snapped up every increase in speed. Although some worried about pricing themselves out of the market, the high-right policy was in full force by the mid-1980s, notably due to Jean-Louis Gassée's mantra of "fifty-five or die", referring to the 55% profit margins of the Macintosh II. + +This policy began to backfire in the last years of the decade as desktop publishing programs appeared on PC clones that offered some or much of the same functionality of the Macintosh, but at far lower price points. The company lost its dominant position in the desktop publishing market and estranged many of its original consumer customer base who could no longer afford their high-priced products. The Christmas season of 1989 was the first in the company's history to have declining sales, which led to a 20% drop in Apple's stock price. During this period, the relationship between Sculley and Gassée deteriorated, leading Sculley to effectively demote Gassée in January 1990 by appointing Michael Spindler as the chief operating officer. Gassée left the company later that year. + +1990–1997: Decline and restructuring +The company pivoted strategy and in October 1990 introduced three lower-cost models, the Macintosh Classic, the Macintosh LC, and the Macintosh IIsi, all of which saw significant sales due to pent-up demand. In 1991, Apple introduced the hugely successful PowerBook with a design that set the current shape for almost all modern laptops. The same year, Apple introduced System 7, a major upgrade to the Macintosh operating system, adding color to the interface and introducing new networking capabilities. + +The success of the lower-cost Macs and PowerBook brought increasing revenue. For some time, Apple was doing incredibly well, introducing fresh new products and generating increasing profits in the process. The magazine MacAddict named the period between 1989 and 1991 as the "first golden age" of the Macintosh. +The success of Apple's lower-cost consumer models, especially the LC, also led to the cannibalization of their higher-priced machines. To address this, management introduced several new brands, selling largely identical machines at different price points, aimed at different markets: the high-end Quadra models, the mid-range Centris line, and the consumer-marketed Performa series. This led to significant market confusion, as customers did not understand the difference between models. + +The early 1990s also saw the discontinuation of the Apple II series, which was expensive to produce, and the company felt was still taking sales away from lower-cost Macintosh models. After the launch of the LC, Apple began encouraging developers to create applications for Macintosh rather than Apple II, and authorized salespersons to direct consumers towards Macintosh and away from Apple II. The Apple IIe was discontinued in 1993. + +Throughout this period, Microsoft continued to gain market share with its Windows graphical user interface that it sold to manufacturers of generally less expensive PC clones. While the Macintosh was more expensive, it offered a more tightly integrated user experience, but the company struggled to make the case to consumers. + +Apple also experimented with a number of other unsuccessful consumer targeted products during the 1990s, including digital cameras, portable CD audio players, speakers, video game consoles, the eWorld online service, and TV appliances. Most notably, enormous resources were invested in the problem-plagued Newton tablet division, based on John Sculley's unrealistic market forecasts. + +Throughout this period, Microsoft continued to gain market share with Windows by focusing on delivering software to inexpensive personal computers, while Apple was delivering a richly engineered but expensive experience. Apple relied on high profit margins and never developed a clear response; instead, they sued Microsoft for using a GUI similar to the Apple Lisa in Apple Computer, Inc. v. Microsoft Corp. The lawsuit dragged on for years before it was finally dismissed. + +The major product flops and the rapid loss of market share to Windows sullied Apple's reputation, and in 1993 Sculley was replaced as CEO by Michael Spindler. + +With Spindler at the helm, Apple, IBM, and Motorola formed the AIM alliance in 1994 with the goal of creating a new computing platform (the PowerPC Reference Platform; PReP), which would use IBM and Motorola hardware coupled with Apple software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind and thus counter the dominance of Windows. The same year, Apple introduced the Power Macintosh, the first of many Apple computers to use Motorola's PowerPC processor. + +In the wake of the alliance, Apple opened up to the idea of allowing Motorola and other companies to build Macintosh clones. Over the next two years, 75 distinct Macintosh clone models were introduced. However, by 1996, Apple executives were worried that the clones were cannibalizing sales of their own high-end computers, where profit margins were highest. + +In 1996, Spindler was replaced by Gil Amelio as CEO. Hired for his reputation as a corporate rehabilitator, Amelio made deep changes, including extensive layoffs and cost-cutting. + +This period was also marked by numerous failed attempts to modernize the Macintosh operating system (MacOS). The original Macintosh operating system (System 1) was not built for multitasking (running several applications at once). The company attempted to correct this with by introducing cooperative multitasking in System 5, but the company still felt it needed a more modern approach. This led to the Pink project in 1988, A/UX that same year, Copland in 1994, and the attempted purchase of BeOS in 1996. Talks with Be stalled when the CEO, former Apple executive Jean-Louis Gassée, demanded $300 million instead of the $125 million Apple wanted to pay. + +Only weeks away from bankruptcy, Apple's board decided NeXTSTEP was a better choice for its next operating system and purchased NeXT in late 1996 for $400 million, bringing back Apple co-founder Steve Jobs. + +1997–2007: Return to profitability +The NeXT acquisition was finalized on February 9, 1997, and the board brought Jobs back to Apple as an advisor. On July 9, 1997, Jobs staged a boardroom coup that resulted in Amelio's resignation after overseeing a three-year record-low stock price and crippling financial losses. + +The board named Jobs as interim CEO and he immediately began a review of the company's products. Jobs would order 70% of the company's products to be cancelled, resulting in the loss of 3,000 jobs, and taking Apple back to the core of its computer offerings. The next month, in August 1997, Steve Jobs convinced Microsoft to make a $150 million investment in Apple and a commitment to continue developing software for the Mac. The investment was seen as an "antitrust insurance policy" for Microsoft who had recently settled with the Department of Justice over anti-competitive practices. Jobs also ended the Mac clone deals and in September 1997, purchased the largest clone maker, Power Computing. On November 10, 1997, Apple introduced the Apple Store website, which was tied to a new build-to-order manufacturing that had been successfully used by PC manufacturer Dell. + +The moves paid off for Jobs; at the end of his first year as CEO, the company turned a $309 million profit. + +On May 6, 1998, Apple introduced a new all-in-one computer reminiscent of the original Macintosh: the iMac. The iMac was a huge success for Apple selling 800,000 units in its first five months and ushered in major shifts in the industry by abandoning legacy technologies like the -inch diskette, being an early adopter of the USB connector, and coming pre-installed with internet connectivity (the "i" in iMac) via Ethernet and a dial-up modem. The device also had a striking teardrop shape and translucent materials, designed by Jonathan Ive, who although hired by Amelio, would go on to work collaboratively with Jobs for the next decade to chart a new course the design of Apple's products. + +A little more than a year later on July 21, 1999, Apple introduced the iBook, a laptop for consumers. It was the culmination of a strategy established by Jobs to produce only four products: refined versions of the Power Macintosh G3 desktop and PowerBook G3 laptop for professionals, along with the iMac desktop and iBook laptop for consumers. Jobs felt the small product line allowed for a greater focus on quality and innovation. + +At around the same time, Apple also completed numerous acquisitions to create a portfolio of digital media production software for both professionals and consumers. Apple acquired of Macromedia's Key Grip digital video editing software project which was renamed Final Cut Pro when it was launched on the retail market in April 1999. The development of Key Grip also led to Apple's release of the consumer video-editing product iMovie in October 1999. Next, Apple successfully acquired the German company Astarte in April 2000, which had developed the DVD authoring software DVDirector, which Apple would sell as the professional-oriented DVD Studio Pro software product, and used the same technology to create iDVD for the consumer market. In 2000, Apple purchased the SoundJam MP audio player software from Casady & Greene. Apple renamed the program iTunes, while simplifying the user interface and adding the ability to burn CDs. + +2001 would be a pivotal year for the Apple with the company making three announcements that would change the course of the company. + +The first announcement came on March 24, 2001, that Apple was nearly ready to release a new modern operating system, Mac OS X. The announcement came after numerous failed attempts in the early 1990s, and several years of development. Mac OS X was based on NeXTSTEP, OPENSTEP, and BSD Unix, with Apple aiming to combine the stability, reliability, and security of Unix with the ease of use afforded by an overhauled user interface, heavily influenced by NeXTSTEP. To aid users in migrating from Mac OS 9, the new operating system allowed the use of OS 9 applications within Mac OS X via the Classic Environment. + +In May 2001, the company opened its first two Apple Store retail locations in Virginia and California, offering an improved presentation of the company's products. At the time, many speculated that the stores would fail, but they went on to become highly successful, and the first of more than 500 stores around the world. + +On October 23, 2001, Apple debuted the iPod portable digital audio player. The product, which was first sold on November 10, 2001, was phenomenally successful with over 100 million units sold within six years. + +In 2003, Apple's iTunes Store was introduced. The service offered music downloads for 99¢ a song and integration with the iPod. The iTunes Store quickly became the market leader in online music services, with over five billion downloads by June 19, 2008. Two years later, the iTunes Store was the world's largest music retailer. + +In 2002, Apple purchased Nothing Real for their advanced digital compositing application Shake, as well as Emagic for the music productivity application Logic. The purchase of Emagic made Apple the first computer manufacturer to own a music software company. The acquisition was followed by the development of Apple's consumer-level GarageBand application. The release of iPhoto in the same year completed the iLife suite. +At the Worldwide Developers Conference keynote address on June 6, 2005, Jobs announced that Apple would move away from PowerPC processors, and the Mac would transition to Intel processors in 2006. On January 10, 2006, the new MacBook Pro and iMac became the first Apple computers to use Intel's Core Duo CPU. By August 7, 2006, Apple made the transition to Intel chips for the entire Mac product line—over one year sooner than announced. The Power Mac, iBook, and PowerBook brands were retired during the transition; the Mac Pro, MacBook, and MacBook Pro became their respective successors. On April 29, 2009, The Wall Street Journal reported that Apple was building its own team of engineers to design microchips. Apple also introduced Boot Camp in 2006 to help users install Windows XP or Windows Vista on their Intel Macs alongside Mac OS X. + +Apple's success during this period was evident in its stock price. Between early 2003 and 2006, the price of Apple's stock increased more than tenfold, from around $6 per share (split-adjusted) to over $80. When Apple surpassed Dell's market cap in January 2006, Jobs sent an email to Apple employees saying Dell's CEO Michael Dell should eat his words. Nine years prior, Dell had said that if he ran Apple he would "shut it down and give the money back to the shareholders". + +2007–2011: Success with mobile devices + +During his keynote speech at the Macworld Expo on January 9, 2007, Jobs announced that Apple Computer, Inc. would thereafter be known as "Apple Inc.", because the company had shifted its emphasis from computers to consumer electronics. This event also saw the announcement of the iPhone and the Apple TV. The company sold 270,000 iPhone units during the first 30 hours of sales, and the device was called "a game changer for the industry". + +In an article posted on Apple's website on February 6, 2007, Jobs wrote that Apple would be willing to sell music on the iTunes Store without digital rights management (DRM), thereby allowing tracks to be played on third-party players if record labels would agree to drop the technology. On April 2, 2007, Apple and EMI jointly announced the removal of DRM technology from EMI's catalog in the iTunes Store, effective in May 2007. Other record labels eventually followed suit and Apple published a press release in January 2009 to announce that all songs on the iTunes Store are available without their FairPlay DRM. + +In July 2008, Apple launched the App Store to sell third-party applications for the iPhone and iPod Touch. Within a month, the store sold 60 million applications and registered an average daily revenue of $1 million, with Jobs speculating in August 2008 that the App Store could become a billion-dollar business for Apple. By October 2008, Apple was the third-largest mobile handset supplier in the world due to the popularity of the iPhone. + +On January 14, 2009, Jobs announced in an internal memo that he would be taking a six-month medical leave of absence from Apple until the end of June 2009 and would spend the time focusing on his health. In the email, Jobs stated that "the curiosity over my personal health continues to be a distraction not only for me and my family, but everyone else at Apple as well", and explained that the break would allow the company "to focus on delivering extraordinary products". Though Jobs was absent, Apple recorded its best non-holiday quarter (Q1 FY 2009) during the recession with revenue of $8.16 billion and profit of $1.21 billion. + +After years of speculation and multiple rumored "leaks", Apple unveiled a large screen, tablet-like media device known as the iPad on January 27, 2010. The iPad ran the same touch-based operating system as the iPhone, and all iPhone apps were compatible with the iPad. This gave the iPad a large app catalog on launch, though having very little development time before the release. Later that year on April 3, 2010, the iPad was launched in the U.S. It sold more than 300,000 units on its first day, and 500,000 by the end of the first week. In May of the same year, Apple's market cap exceeded that of competitor Microsoft for the first time since 1989. + +In June 2010, Apple released the iPhone 4, which introduced video calling using FaceTime, multitasking, and a new uninsulated stainless steel design that acted as the phone's antenna. Later that year, Apple again refreshed its iPod line of MP3 players by introducing a multi-touch iPod Nano, an iPod Touch with FaceTime, and an iPod Shuffle that brought back the clickwheel buttons of earlier generations. It also introduced the smaller, cheaper second generation Apple TV which allowed renting of movies and shows.
