Civil rights movement

The civil rights movement was a social movement in the United States from 1954 to 1968 which aimed to abolish legalized racial segregation, discrimination, and disenfranchisement in the country, which most commonly affected African Americans. The movement had origins in the Reconstruction era in the late 19th century, and modern roots in the 1940s. After years of nonviolent protests and civil disobedience campaigns, the civil rights movement achieved many of its legislative goals in the 1960s, during which it secured new protections in federal law for the civil rights of all Americans. Following the American Civil War (1861–1865), the three Reconstruction Amendments to the U.S. Constitution abolished slavery and granted citizenship to all African Americans, the majority of whom had recently been enslaved in the southern states. During Reconstruction, African-American men in the South voted and held political office, but after 1877 they were increasingly deprived of civil rights under racist Jim Crow laws (which for example banned interracial marriage, introduced literacy tests for voters, and segregated schools) and were subjected to violence from white supremacists during the nadir of American race relations. African Americans who moved to the North in order to improve their prospects in the Great Migration also faced barriers in employment and housing. Legal racial discrimination was upheld by the Supreme Court in its 1896 decision in Plessy v. Ferguson, which established the doctrine of "separate but equal". The movement for civil rights, led by figures such as W. E. B. Du Bois and Booker T. Washington, achieved few gains until after World War II. In 1948, President Harry S. Truman issued an executive order abolishing discrimination in the armed forces. In 1954, the Supreme Court struck down state laws establishing racial segregation in public schools in Brown v. Board of Education. A mass movement for civil rights, led by Martin Luther King Jr. and others, began a campaign of nonviolent protests and civil disobedience including the Montgomery bus boycott in 1955–1956, "sit-ins" in Greensboro and Nashville in 1960, the Birmingham campaign in 1963, and a march from Selma to Montgomery in 1965. Press coverage of events such as the lynching of Emmett Till in 1955 and the use of fire hoses and dogs against protesters in Birmingham increased public support for the civil rights movement. In 1963, about 250,000 people participated in the March on Washington, after which President John F. Kennedy asked Congress to pass civil rights legislation. Kennedy's successor, Lyndon B. Johnson, overcame the opposition of southern politicians to pass three major laws: the Civil Rights Act of 1964, which prohibited discrimination based on race, color, religion, sex, or national origin in public accommodations, employment, and federally assisted programs; the Voting Rights Act of 1965, which outlawed discriminatory voting laws and authorized federal oversight of election law in areas with a history of voter suppression; and the Fair Housing Act of 1968, which banned housing discrimination. The Supreme Court made further pro–civil rights rulings in cases including Browder v. Gayle (1956) and Loving v. Virginia (1967), banning segregation in public transport and striking down laws against interracial marriage. The new civil rights laws ended most legal discrimination against African Americans, though informal racism remained. In the mid-1960s, the Black power movement emerged, which criticized leaders of the civil rights movement for their moderate and incremental tendencies. A wave of civil unrest in Black communities between 1964 and 1969, which peaked in 1967 and after the assassination of King in 1968, weakened support for the movement from White moderates. Despite affirmative action and other programs which expanded opportunities for Black and other minorities in the U.S. by the early 21st century, racial gaps in income, housing, education, and criminal justice continue to persist. == Background == === American Civil War and Reconstruction era === Before the American Civil War, eight serving presidents had owned slaves, almost four million black people remained enslaved in the South, generally only white men with property could vote, and the Naturalization Act of 1790 limited U.S. citizenship to whites. Following the Civil War, three constitutional amendments were passed, including the 13th Amendment (1865) that ended slavery; the 14th Amendment (1869) that gave black people citizenship, adding their total for Congressional apportionment; and the 15th Amendment (1870) that gave black males the right to vote (only males could vote in the U.S. at the time). From 1865 to 1877, the United States underwent a turbulent Reconstruction era during which the federal government tried to establish free labor and the civil rights of freedmen in the South after the end of slavery. Many whites resisted the social changes, leading to the formation of insurgent movements such as the Ku Klux Klan (KKK), whose members attacked black and white Republicans in order to maintain white supremacy. In 1871, President Ulysses S. Grant, the U.S. Army, and U.S. Attorney General Amos T. Akerman, initiated a campaign to repress the KKK under the Enforcement Acts. Some states were reluctant to enforce the federal measures of the act. In addition, by the early 1870s, other white supremacist and insurgent paramilitary groups arose that violently opposed African-American legal equality and suffrage, intimidating and suppressing black voters, and assassinating Republican officeholders. However, if the states failed to implement the acts, the laws allowed the Federal Government to get involved. Many Republican governors were afraid of sending black militia troops to fight the Klan for fear of war. === Disenfranchisement after Reconstruction === After the disputed election of 1876, which resulted in the end of Reconstruction and the withdrawal of federal troops, whites in the South regained political control of the region's state legislatures. They continued to intimidate and violently attack blacks before and during elections to suppress their voting, but the last African Americans were elected to Congress from the South before disenfranchisement of blacks by states throughout the region, as described below. From 1890 to 1908, southern states passed new constitutions and laws to disenfranchise African Americans and many Poor Whites by creating barriers to voter registration; voting rolls were dramatically reduced as blacks and poor whites were forced out of electoral politics. After the landmark Supreme Court case of Smith v. Allwright (1944), which prohibited white primaries, progress was made in increasing black political participation in the Rim South and Acadiana – although almost entirely in urban areas and a few rural localities where most blacks worked outside plantations. The status quo ante of excluding African Americans from the political system lasted in the remainder of the South, especially North Louisiana, Mississippi and Alabama, until national civil rights legislation was passed in the mid-1960s to provide federal enforcement of constitutional voting rights. For more than sixty years, blacks in the South were essentially excluded from politics, unable to elect anyone to represent their interests in Congress or local government. Since they could not vote, they could not serve on local juries. During this period, the white-dominated Democratic Party maintained political control of the South. With whites controlling all the seats representing the total population of the South, they had a powerful voting bloc in Congress. The Republican Party—the "party of Lincoln" and the party to which most blacks had belonged—shrank to insignificance except in remote Unionist areas of Appalachia and the Ozarks as black voter registration was suppressed. The Republican lily-white movement also gained strength by excluding blacks. Until 1965, the "Solid South" was a one-party system under the white Democrats. Excepting the previously noted historic Unionist strongholds the Democratic Party nomination was tantamount to election for state and local office. In 1901, President Theodore Roosevelt invited Booker T. Washington, president of the Tuskegee Institute, to dine at the White House, making him the first African American to attend an official dinner there. "The invitation was roundly criticized by southern politicians and newspapers." Washington persuaded the president to appoint more blacks to federal posts in the South and to try to boost African-American leadership in state Republican organizations. However, these actions were resisted by both white Democrats and white Republicans as an unwanted federal intrusion into state politics. During the same time as African Americans were being disenfranchised, white southerners imposed racial segregation by law. Violence against blacks increased, with numerous lynchings through the turn of the century. The system of de jure state-sanctioned racial discrimination and oppression that emerged from the post-Reconstruction South became known as the "Jim Crow" system. The United States Supreme Court made up almost entirely of Northerners, upheld the constitutionality of those state laws that required racial segregation in public facilities in its 1896 decision Plessy v. Ferguson, legitimizing them through the "separate but equal" doctrine. Segregation, which began with slavery, continued with Jim Crow laws, with signs used to show blacks where they could legally walk, talk, drink, rest, or eat. For those places that were racially mixed, non-whites had to wait until all white customers were served first. Elected in 1912, President Woodrow Wilson gave in to demands by Southern members of his cabinet who ordered segregation of workplaces in the federal government. The early 20th century is a period often referred to as the "nadir of American race relations", when the number of lynchings was highest. While tensions and civil rights violations were most intense in the South, social discrimination affected African Americans in other regions as well. At the national level, the Southern bloc controlled important committees in Congress, defeated passage of federal laws against lynching, and exercised considerable power beyond the number of whites in the South. Characteristics of the post-Reconstruction period: Racial segregation. By law, public facilities and government services such as education were divided into separate "white" and "colored" domains. Characteristically, those for colored were underfunded and of inferior quality. Disenfranchisement. When white Democrats regained power, they passed laws that made voter registration more restrictive, essentially forcing black voters off the voting rolls. The number of African-American voters dropped dramatically, and they were no longer able to elect representatives. From 1890 to 1908, Southern states of the former Confederacy created constitutions with provisions that disfranchised tens of thousands of African Americans, and U.S. states such as Alabama disenfranchised poor whites as well. Exploitation. Increased economic oppression of blacks through the convict lease system, denial of economic opportunities, and widespread employment discrimination. Violence. Individual, police, paramilitary, organizational, and mob racial violence against blacks . African Americans rejected this regime. They resisted it in numerous ways and sought better opportunities through lawsuits, new organizations, political redress, and labor organizing (see the Civil rights movement (1896–1954)). The National Association for the Advancement of Colored People (NAACP) was founded in 1909. It fought to end race discrimination through litigation, education, and lobbying efforts. Its crowning achievement was its legal victory in the Supreme Court decision Brown v. Board of Education (1954), when the Supreme Court ruled that segregation of public schools in the US was unconstitutional and, by implication, overturned the "separate but equal" doctrine established in Plessy v. Ferguson of 1896. Following the unanimous Supreme Court ruling, many states began to gradually integrate their schools, but some areas of the South resisted by closing public schools altogether. The integration of Southern public libraries followed demonstrations and protests that used techniques seen in other elements of the larger civil rights movement. This included sit-ins, beatings, and white resistance. For example, in 1963 in the city of Anniston, Alabama, two black ministers were brutally beaten for attempting to integrate the public library. Though there was resistance and violence, the integration of libraries was generally quicker than the integration of other public institutions. === National issues === The situation for blacks outside the South was somewhat better (in most states they could vote and have their children educated, though they still faced discrimination in housing and jobs). In 1900 Reverend Matthew Anderson, speaking at the annual Hampton Negro Conference in Virginia, said that "...the lines along most of the avenues of wage-earning are more rigidly drawn in the North than in the South. There seems to be an apparent effort throughout the North, especially in the cities to debar the colored worker from all the avenues of higher remunerative labor, which makes it more difficult to improve his economic condition even than in the South." From 1910 to 1970, blacks sought better lives by migrating north and west out of the South. A total of nearly seven million blacks left the South in what was known as the Great Migration, most during and after World War II. So many people migrated that the demographics of some previously black-majority states changed to a white majority (in combination with other developments). The rapid influx of blacks altered the demographics of Northern and Western cities; happening at a period of expanded European, Hispanic, and Asian immigration, it added to social competition and tensions, with the new migrants and immigrants battling for a place in jobs and housing. Reflecting social tensions after World War I, as veterans struggled to return to the workforce and labor unions were organizing, the Red Summer of 1919 was marked by hundreds of deaths and higher casualties across the U.S. as a result of white race riots against blacks that took place in more than three dozen cities. Urban problems such as crime and disease were blamed on the large influx of Southern blacks to cities in the north and west, based on stereotypes of rural southern African-Americans. Overall, blacks in Northern and Western cities experienced systemic discrimination in a plethora of aspects of life. Within employment, economic opportunities for blacks were routed to the lowest status and restrictive in potential mobility. Within the housing market, stronger discriminatory measures were used in correlation to the influx, resulting in a mix of "targeted violence, restrictive covenants, redlining and racial steering". The Great Migration resulted in many African Americans becoming urbanized, and they began to realign from the Republican to the Democratic Party, especially because of opportunities under the New Deal of the Franklin D. Roosevelt administration during the Great Depression in the 1930s. Substantially under pressure from African-American supporters who began the March on Washington Movement, President Roosevelt issued the first federal order banning discrimination and created the Fair Employment Practice Committee. After both World Wars, black veterans of the military pressed for full civil rights and often led activist movements. In 1948, President Harry Truman issued Executive Order 9981, which ended segregation in the military. Housing segregation became a nationwide problem following the Great Migration of black people out of the South. Racial covenants were employed by many real estate developers to "protect" entire subdivisions, with the primary intent to keep "white" neighborhoods "white". Ninety percent of the housing projects built in the years following World War II were racially restricted by such covenants. Cities known for their widespread use of racial covenants include Chicago, Baltimore, Detroit, Milwaukee, Los Angeles, Seattle, and St. Louis. Said premises shall not be rented, leased, or conveyed to, or occupied by, any person other than of the white or Caucasian race. While many whites defended their space with violence, intimidation, or legal tactics toward black people, many other whites migrated to more racially homogeneous suburban or exurban regions, a process known as white flight. From the 1930s to the 1960s, the National Association of Real Estate Boards (NAREB) issued guidelines that specified that a realtor "should never be instrumental in introducing to a neighborhood a character or property or occupancy, members of any race or nationality, or any individual whose presence will be clearly detrimental to property values in a neighborhood." The result was the development of all-black ghettos in the North and West, where much housing was older, as well as South. The first anti-miscegenation law was passed by the Maryland General Assembly in 1691, criminalizing interracial marriage. In a speech in Charleston, Illinois in 1858, Abraham Lincoln stated, "I am not, nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people". By the late 1800s, 38 US states had anti-miscegenation statutes. By 1924, the ban on interracial marriage was still in force in 29 states. While interracial marriage had been legal in California since 1948, in 1957 actor Sammy Davis Jr. faced a backlash for his involvement with white actress Kim Novak. Davis briefly married a black dancer in 1958 to protect himself from mob violence. In 1958, officers in Virginia entered the home of Mildred and Richard Loving and dragged them out of bed for living together as an interracial couple, on the basis that "any white person intermarry with a colored person"— or vice versa—each party "shall be guilty of a felony" and face prison terms of five years. Invigorated by the victory of Brown and frustrated by the lack of immediate practical effect, private citizens increasingly rejected gradualist, legalistic approaches as the primary tool to bring about desegregation. They were faced with "massive resistance" in the South by proponents of racial segregation and voter suppression. In defiance, African-American activists adopted a combined strategy of direct action, nonviolence, nonviolent resistance, and many events described as civil disobedience, giving rise to the civil rights movement of 1954 to 1968. A. Philip Randolph had planned a march on Washington, D.C., in 1941 to support demands for elimination of employment discrimination in the defense industry; he called off the march when the Roosevelt administration met the demand by issuing Executive Order 8802, which barred racial discrimination and created an agency to oversee compliance with the order. === Protests begin === The strategy of public education, legislative lobbying, and litigation that had typified the civil rights movement during the first half of the 20th century broadened after Brown to a strategy that emphasized "direct action": boycotts, sit-ins, Freedom Rides, marches or walks, and similar tactics that relied on mass mobilization, nonviolent resistance, standing in line, and, at times, civil disobedience. Churches, local grassroots organizations, fraternal societies, and black-owned businesses mobilized volunteers to participate in broad-based actions. This was a more direct and potentially more rapid means of creating change than the traditional approach of mounting court challenges used by the NAACP and others. In 1952, the Regional Council of Negro Leadership (RCNL), led by T. R. M. Howard, a black surgeon, entrepreneur, and planter organized a successful boycott of gas stations in Mississippi that refused to provide restrooms for blacks. Through the RCNL, Howard led campaigns to expose brutality by the Mississippi state highway patrol and to encourage blacks to make deposits in the black-owned Tri-State Bank of Nashville which, in turn, gave loans to civil rights activists who were victims of a "credit squeeze" by the White Citizens' Councils. After Claudette Colvin was arrested for not giving up her seat on a Montgomery, Alabama bus in March 1955, a bus boycott was considered and rejected. But when Rosa Parks was arrested in December, Jo Ann Gibson Robinson of the Montgomery Women's Political Council put the bus boycott protest in motion. Late that night, she, John Cannon (chairman of the Business Department at Alabama State University) and others mimeographed and distributed thousands of leaflets calling for a boycott. The eventual success of the boycott made its spokesman Martin Luther King Jr., a nationally known figure. It also inspired other bus boycotts, such as the successful Tallahassee, Florida boycott of 1956–57. This movement also sparked the 1956 Sugar Bowl riots in Atlanta which later became a major organizing center of the civil rights movement, with Martin Luther King Jr. In 1957, King and Ralph Abernathy, the leaders of the Montgomery Improvement Association, joined with other church leaders who had led similar boycott efforts, such as C. K. Steele of Tallahassee and T. J. Jemison of Baton Rouge, and other activists such as Fred Shuttlesworth, Ella Baker, A. Philip Randolph, Bayard Rustin and Stanley Levison, to form the Southern Christian Leadership Conference (SCLC). The SCLC, with its headquarters in Atlanta, Georgia, did not attempt to create a network of chapters as the NAACP did. It offered training and leadership assistance for local efforts to fight segregation. The headquarters organization raised funds, mostly from Northern sources, to support such campaigns. It made nonviolence both its central tenet and its primary method of c

African Americans

African Americans, also known as Black Americans and formerly also called Afro-Americans, are an American racial or ethnic group consisting of Americans with partial or total ancestry from any of the Black racial groups of Africa. African Americans constitute the second largest ethno-racial group in the US after White Americans. The term "African American" generally denotes descendants of Africans enslaved in the United States. Most African Americans are descendants of enslaved people within the boundaries of the present United States. While some Black immigrants or their children may also come to identify as African American, the majority of first-generation immigrants do not, preferring to identify with their nation of origin. Most African Americans are of West African and coastal Central African ancestry, with varying amounts of Western European and Native American ancestry. African-American history began in the 16th century, with Africans from West Africa and coastal Central Africa being sold to European slave traders and transported across the Atlantic to the Western Hemisphere. After arriving in the Americas, they were sold as slaves to European colonists and put to work on plantations, particularly in the southern colonies. A few were able to achieve freedom through manumission or escape, and founded independent communities before and during the American Revolution. After the United States was founded in 1783, most Black people continued to be enslaved, primarily concentrated in the American South, with four million enslaved people only liberated during and at the end of the Civil War in 1865. During Reconstruction, they gained citizenship and adult-males the right to vote; however, due to the widespread policy and ideology of White supremacy, they were largely treated as second-class citizens and found themselves soon disenfranchised in the South. These circumstances changed due to participation in the military conflicts of the United States, substantial migration out of the South, the elimination of legal racial segregation, and the civil rights movement which sought political and social freedom. However, racism against African Americans and racial socioeconomic disparity remain a problem into the 21st century. In the 20th and 21st centuries, immigration has played an increasingly significant role in the African-American community. As of 2022, 10% of Black Americans were immigrants, and 20% were either immigrants or the children of immigrants. In 2008, Barack Obama became the first, and so far only, African American to be elected president of the United States. Kamala Harris became the nation's first African-American vice president in 2020. African-American culture has had a significant influence on worldwide culture, making numerous contributions to visual arts, literature, the English language, philosophy, politics, cuisine, sports, and music. The African-American contribution to popular music is so profound that most American music, including jazz, gospel, blues, rock and roll, funk, disco, house, techno, hip hop, R&B, trap, and soul, has its origins either partially or entirely in the African-American community. == History == === Colonial era === The vast majority of those who were enslaved and transported in the transatlantic slave trade were people from several Central and West Africa ethnic groups. They had been captured directly by the slave traders in coastal raids, or sold by other West Africans, or by half-European "merchant princes" to European slave traders, who brought them to the Americas. The first African slaves in what is now the United States arrived in the early 16th century. Africans were Among Juan Ponce de León's 1513 voyage that landed in what would become Spanish Florida, and enslaved Africans arrived around the same time to Spanish Puerto Rico. Africans also came via Santo Domingo in the Caribbean to the San Miguel de Gualdape colony (most likely located in the Winyah Bay area of present-day South Carolina), founded by Spanish explorer Lucas Vázquez de Ayllón in 1526. The ill-fated colony was almost immediately disrupted by a fight over leadership, during which the slaves revolted and fled the colony to seek refuge among local Native Americans. De Ayllón and many of the colonists died shortly afterward, due to an epidemic and the colony was abandoned. The settlers and the slaves who had not escaped returned to the Island of Hispaniola, whence they had come. The enslaved explorer Esteban arrived in Florida with the Narváez expedition in 1528, a journey that first landed in Santo Domingo and later traveled into Spanish Texas and the Southwest before ending in Mexico. The marriage between Luisa de Abrego, a free Black domestic servant from Seville, and Miguel Rodríguez, a White Segovian conquistador in 1565 in St. Augustine (Spanish Florida), is the first known and recorded Christian marriage anywhere in what is now the continental United States. The first recorded Africans in English America (including most of the future United States) were "20 and odd negroes" who arrived in Jamestown, Virginia via Cape Comfort in August 1619 as indentured servants. As many Virginian settlers began to die from harsh conditions, more and more Africans were brought to work as laborers. An indentured servant (who could be White or Black) would work for several years (usually four to seven) without wages. The status of indentured servants in early Virginia and Maryland was similar to slavery. Servants could be bought, sold, or leased, and they could be physically beaten for disobedience or attempting to running away. Unlike slaves, they were freed after their term of service expired or if their freedom was purchased. Their children did not inherit their status, and on their release from contract they received "a year's provision of corn, double apparel, tools necessary", and a small cash payment called "freedom dues". Africans could legally raise crops and cattle to purchase their freedom. They raised families, married other Africans and sometimes intermarried with Native Americans or European settlers. By the 1640s and 1650s, several African families owned farms around Jamestown, and some became wealthy by colonial standards and purchased indentured servants of their own. In 1640, the Virginia General Court recorded the earliest documentation of lifetime slavery when they sentenced John Punch, a Negro, to lifetime servitude under his master Hugh Gwyn, for running away. In Spanish Florida, some Spanish married or had unions with Pensacola, Creek or African women, both enslaved and free, and their descendants created a mixed-race population of mestizos and mulattos. The Spanish encouraged slaves from the colony of Georgia to come to Florida as a refuge, promising freedom in exchange for conversion to Catholicism. King Charles II issued a royal proclamation freeing all slaves who fled to Spanish Florida and accepted conversion and baptism. Most went to the area around St. Augustine, but escaped slaves also reached Pensacola. St. Augustine had mustered an all-Black militia unit defending Spanish Florida as early as 1683. One of the Dutch African arrivals, Anthony Johnson, would later own one of the first Black "slaves", John Casor, resulting from the court ruling of a civil case. The popular conception of a race-based slave system did not fully develop until the 18th century. The Dutch West India Company introduced slavery in 1625 with the importation of eleven Black slaves into New Amsterdam (present-day New York City). All the colony's slaves, however, were freed upon its surrender to the English. Massachusetts was the first English colony to legally recognize slavery in 1641. In 1662, Virginia passed a law that children of enslaved women would take the status of the mother, rather than that of the father, as was the case under common law. This legal principle was called partus sequitur ventrum. By an act of 1699, Virginia ordered the deportation of all free Blacks, effectively defining all people of African descent who remained in the colony as slaves. In 1670, the colonial assembly passed a law prohibiting free and baptized Blacks (and Native Americans) from purchasing Christians (in this act meaning White Europeans) but allowing them to buy people "of their owne nation". In Spanish Louisiana, although there was no movement toward abolition of the African slave trade, Spanish rule introduced a new law called coartación, which allowed slaves to buy their freedom, and that of others. Although some did not have the money to do so, government measures on slavery enabled the existence of many free Blacks. This caused problems to the Spaniards with the French creoles (French who had settled in New France) who had also populated Spanish Louisiana. The French creoles cited that measure as one of the system's worst elements. First established in South Carolina in 1704, groups of armed White men—slave patrols—were formed to monitor enslaved Black people. Their function was to police slaves, especially fugitives. Slave owners feared that slaves might organize revolts or slave rebellions, so state militias were formed to provide a military command structure and discipline within the slave patrols. These patrols were used to detect, encounter, and crush any organized slave meetings which might lead to revolts or rebellions. The earliest African American congregations and churches were organized before 1800 in both northern and southern cities following the Great Awakening. By 1775, Africans made up 20% of the population in the American colonies, which made them the second largest ethnic group after English Americans. === From the American Revolution to the Civil War === During the 1770s, Africans, both enslaved and free, helped rebellious American colonists secure their independence by defeating the British in the American Revolutionary War. Blacks played a role in both sides in the American Revolution. Activists in the Patriot cause included James Armistead, Prince Whipple, and Oliver Cromwell. Around 15,000 Black Loyalists left with the British after the war, most of them ending up as free Black people in England or its colonies, such as the Black Nova Scotians and the Sierra Leone Creole people. In the Spanish Louisiana, Governor Bernardo de Gálvez organized Spanish free Black men into two militia companies to defend New Orleans during the American Revolution. They fought in the 1779 battle in which Spain captured Baton Rouge from the British. Gálvez also commanded them in campaigns against the British outposts in Mobile, Alabama, and Pensacola, Florida. He recruited slaves for the militia by pledging to free anyone who was seriously wounded and promised to secure a low price for coartación (buy their freedom and that of others) for those who received lesser wounds. During the 1790s, Governor Francisco Luis Héctor, baron of Carondelet reinforced local fortifications and recruit even more free Black men for the militia. Carondelet doubled the number of free Black men who served, creating two more militia companies—one made up of Black members and the other of pardo (mixed race). Serving in the militia brought free Black men one step closer to equality with Whites, allowing them, for example, the right to carry arms and boosting their earning power. However, actually these privileges distanced free Black men from enslaved Blacks and encouraged them to identify with Whites. Slavery had been tacitly enshrined in the US Constitution through provisions such as Article I, Section 2, Clause 3, commonly known as the 3/5 compromise. Due to the restrictions of Section 9, Clause 1, Congress was unable to pass an Act Prohibiting Importation of Slaves until 1807. Fugitive slave laws (derived from the Fugitive Slave Clause of the Constitution—Article IV, Section 2, Clause 3) were passed by Congress in both 1793 and 1850, guaranteeing the right of a slaveholder to recover an escaped slave anywhere within the US. Slave owners, who viewed enslaved people as property, ensured that it became a federal crime to aid or assist those who had fled slavery or to interfere with their capture. By that time, slavery, which almost exclusively targeted Black people, had become the most critical and contentious political issue in the Antebellum United States, repeatedly sparking crises and conflicts. Among these were the Missouri Compromise, the Compromise of 1850, the infamous Dred Scott decision, and John Brown's raid on Harpers Ferry. Prior to the Civil War, eight serving presidents had owned slaves, a practice that was legally protected under the US Constitution. By 1860, the number of enslaved Black people in the US had grown to between 3.5 and 4.4 million, largely as a result of the Atlantic slave trade. In addition, 488,000–500,000 Black people lived free (with legislated limits) across the country. With legislated limits imposed upon them in addition to "unconquerable prejudice" from Whites according to Henry Clay. In response to these conditions, some free Black people chose to leave the US and emigrate to Liberia in West Africa. Liberia had been established in 1821 as a settlement by the American Colonization Society (ACS), with many abolitionist members of the ACS believing Black Americans would have greater opportunities for freedom and equality in Africa than they would in the US. Slaves not only represented a significant financial investment for their owners, but they also played a crucial role in producing the country's most valuable product and export: cotton. Enslaved people were instrumental in the construction of several prominent structures such as, the United States Capitol, the White House and other Washington, D.C.–based buildings. Similar building projects existed in the slave states. By 1815, the domestic slave trade had become a significant and major economic activity in the United States, continuing to flourish until the 1860s. Historians estimate that nearly one million individuals were subjected to this forced migration, which was often referred to as a new "Middle Passage". The historian Ira Berlin described this internal forced migration of enslaved people as the "central event" in the life of a slave during the period between the American Revolution and the Civil War. Berlin emphasized that whether enslaved individuals were directly uprooted or lived in constant fear that they or their families would be involuntarily relocated, "the massive deportation traumatized Black people" throughout the US. As a result of this large-scale forced movement, countless individuals lost their connection to families and clans, and many ethnic Africans lost their knowledge of varying tribal origins in Africa. The 1863 photograph of Wilson Chinn, a branded slave from Louisiana, along with the famous image of Gordon and his scarred back, served as two of the earliest and most powerful examples of how the newborn medium of photography could be used to visually document and encapsulate the brutality and cruelty of slavery. Emigration of free Blacks to their continent of origin had been proposed since the Revolutionary war. After Haiti became independent, it tried to recruit African Americans to migrate there after it re-established trade relations with the United States. The Haitian Union was a group formed to promote relations between the countries. After riots against Blacks in Cincinnati, its Black community sponsored founding of the Wilberforce Colony, an initially successful settlement of African American immigrants to Canada. The colony was one of the first such independent political entities. It lasted for a number of decades and provided a destination for about 200 Black families emigrating from a number of locations in the United States. In 1863, during the American Civil War, President Abraham Lincoln signed the Emancipation Proclamation. The proclamation declared that all slaves in Confederate-held territory were free. Advancing Union troops enforced the proclamation, with Texas being the last state to be emancipated, in 1865. Slavery in a few border states continued until the ratification of the Thirteenth Amendment in December 1865. While the Naturalization Act of 1790 limited US citizenship to Whites only, the 14th Amendment (1868) gave Black people citizenship, and the 15th Amendment (1870) gave Black men the right to vote. === Reconstruction era and Jim Crow === African Americans quickly set up congregations for themselves, as well as schools and community/civic associations, to have space away from White control or oversight. While the post-war Reconstruction era was initially a time of progress for African Americans, that period ended in 1876. By the late 1890s, Southern states enacted Jim Crow laws to enforce racial segregation and disenfranchisement. Segregation was now imposed with Jim Crow laws, using signs used to show Blacks where they could legally walk, talk, drink, rest, or eat. For those places that were racially mixed, non-Whites had to wait until all White customers were dealt with. Most African Americans obeyed the Jim Crow laws, to avoid racially motivated violence. To maintain self-esteem and dignity, African Americans such as Anthony Overton and Mary McLeod Bethune continued to build their own schools, churches, banks, social clubs, and other businesses. In the last decade of the 19th century, racially discriminatory laws and racial violence aimed at African Americans began to mushroom in the United States, a period often referred to as the "nadir of American race relations". These discriminatory acts included racial segregation—upheld by the United States Supreme Court decision in Plessy v. Ferguson in 1896—which was legally mandated by southern states and nationwide at the local level of government, voter suppression or disenfranchisement in the southern states, denial of economic opportunity or resources nationwide, and private acts of violence and mass racial violence aimed at African Americans unhindered or encouraged by government authorities. === Great migration and civil rights movement === The desperate conditions of African Americans in the South sparked the Great Migration during the first half of the 20th century which led to a growing African American community in Northern and Western United States. The rapid influx of Blacks disturbed the racial balance within Northern and Western cities, exacerbating hostility between both Blacks and Whites in the two regions. The Red Summer of 1919 was marked by hundreds of deaths and higher casualties across the US as a result of race riots that occurred in more than three dozen cities, such as the Chicago race riot of 1919 and the Omaha race riot of 1919. Overall, Blacks in Northern and Western cities experienced systemic discrimination in a plethora of aspects of life. Within employment, economic opportunities for Blacks were routed to the lowest-status and restrictive in potential mobility. At the 1900 Hampton Negro Conference, Reverend Matthew Anderson said: "...the lines along most of the avenues of wage earning are more rigidly drawn in the North than in the South." Within the housing market, stronger discriminatory measures were used in correlation to the influx, resulting in a mix of "targeted violence, restrictive covenants, redlining and racial steering". While many Whites defended their space with violence, intimidation, or legal tactics toward African Americans, many other Whites migrated to more racially homogeneous suburban or exurban regions, a process known as White flight. Despite discrimination, drawing cards for leaving the hopelessness in the South were the growth of African American institutions and communities in Northern cities. Institutions included Black oriented organizations (e.g., Urban League, NAACP), churches, businesses, and newspapers, as well as successes in the development in African American intellectual culture, music, and popular culture (e.g., Harlem Renaissance, Chicago Black Renaissance). The Cotton Club in Harlem was a Whites-only establishment, with Blacks (such as Duke Ellington) allowed to perform, but to a White audience. Black Americans also found a new ground for political power in Northern cities, without the enforced disabilities of Jim Crow. By the 1950s, the civil rights movement was gaining momentum. A 1955 lynching that sparked public outrage about injustice was that of Emmett Till, a 14-year-old boy from Chicago. Spending the summer with relatives in Money, Mississippi, Till was killed for allegedly having wolf-whistled at a White woman. Till had been badly beaten, one of his eyes was gouged out, and he was shot in the head. The visceral response to his mother's decision to have an open-casket funeral mobilized the Black community throughout the US. Vann R. Newkirk wrote "the trial of his killers became a pageant illuminating the tyranny of White supremacy". The state of Mississippi tried two defendants, but they were speedily acquitted by an all-White jury. One hundred days after Emmett Till's murder, Rosa Parks refused to give up her seat on the bus in Alabama—indeed, Parks told Emmett's mother Mamie Till that "the photograph of Emmett's disfigured face in the casket was set in her mind when she refused to give up her seat on the Montgomery bus." The March on Washington for Jobs and Freedom and the conditions which brought it into being are credited with putting pressure on presidents John F. Kennedy and Lyndon B. Johnson. Johnson put his support behind passage of the Civil Rights Act of 1964 that banned discrimination in public accommodations, employment, and labor unions, and the Voting Rights Act of 1965, which expanded federal authority over states to ensure Black political participation through protection of voter registration and elections. By 1966, the emergence of the Black Power movement, which lasted from 1966 to 1975, expanded upon the aims of the civil rights movement to include economic and political self-sufficiency, and freedom from White authority. During the post-war period, many African Americans continued to be economically disadvantaged relat

United States

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 states and Washington, D.C. as its federal capital district. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclavic state of Alaska in the northwest and the archipelagic state of Hawaii in the Pacific Ocean. Some 574 federally recognized tribal governments and 326 Indian reservations are legally classified as domestic dependent nations with tribal sovereignty rights. The U.S. asserts sovereignty over five major island territories and various uninhabited islands. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 340 million. Paleo-Indians migrated to North America across the Bering land bridge more than 12,000 years ago, and formed various civilizations and societies. Spanish exploration and colonization led to the establishment in 1513 of Spanish Florida, the first European colony in what is now the continental United States. France also began to colonize at this time, but major settlements came much later. Subsequent British colonization led to the first settlement of the Thirteen Colonies in Virginia in 1607. Intensive agriculture in the rapidly expanding Southern Colonies encouraged the forced migration of enslaved Africans. Clashes with the British Crown over taxation and political representation sparked the American Revolution, with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the 1775–1783 Revolutionary War, the country continued to expand westward across North America, dispossessing Native Americans as it fought the Indian Wars. Expansion continued when the U.S. signed the 1803 Louisiana Purchase with Napoleonic France and won the Mexican–American War in 1848. As more states were admitted, a North–South division over slavery led to the secession of the Confederate States of America, which fought the Union in the 1861–1865 American Civil War. With the victory and preservation of the United States, slavery was abolished nationally. By the late 19th century, the United States established itself as a great power with victory in the Spanish–American War, a status solidified with its participation in World War I. Following Japan's attack on Pearl Harbor in December 1941, the U.S. entered World War II. The aftermath of the war left the U.S. and the Soviet Union as the world's two superpowers which led to the Cold War, during which both countries struggled for ideological dominance and international influence. The end of the Cold War and the Soviet Union's collapse in 1991 left the U.S. as the world's sole superpower, with significant geopolitical influence globally. The U.S. national government is a presidential constitutional federal republic and liberal democracy with three separate branches: legislative, executive, and judicial. It has a bicameral national legislature composed of the House of Representatives, a lower house based on population, and the Senate, an upper house based on equal representation for each state. The country's Democratic and Republican parties have dominated American politics since the 1850s. Federalism provides substantial autonomy to the 50 states, while American values are based on a political tradition that draws its inspiration from the European Enlightenment movement. A melting pot of many ethnicities and customs, the culture of the United States has been shaped by centuries of immigration, and its soft power influence has a global reach. One of the world's most developed countries, the U.S. ranks among the highest in economic competitiveness, productivity, innovation, human rights, and higher education. The United States accounted for over a quarter of nominal global economic output in 2024, and its economy has been the world's largest by nominal GDP since about 1890. It possesses by far the largest amount of wealth of any country and has the highest disposable household income per capita among OECD countries, though U.S. wealth inequality is higher than in most other developed countries. The U.S. is a member of multiple international organizations and plays a leading role in global political, cultural, economic, and military affairs. == Etymology == The first documented use of the phrase "United States of America" is a letter from January 2, 1776. Stephen Moylan, a Continental Army aide to General George Washington, wrote to Joseph Reed, Washington's aide-de-camp, seeking to go "with full and ample powers from the United States of America to Spain" to seek assistance in the Revolutionary War effort. The first known public usage is an anonymous essay published in the Williamsburg newspaper, The Virginia Gazette, on April 6, 1776. By June 1776, the "United States of America" appeared in the Articles of Confederation, and in July, the Declaration of Independence. The Second Continental Congress adopted the Declaration of Independence on July 4, 1776. The term "United States" and its initialism "U.S.", used as nouns or as adjectives in English, are common short names for the country. The initialism "USA", a noun, is also common. "United States" and "U.S." are the established terms throughout the U.S. federal government, with prescribed rules. "The States" is an established colloquial shortening of the name, used particularly from abroad; "stateside" is the corresponding adjective or adverb. "America" is the feminine form of the first word of Americus Vesputius, the Latinized name of Italian explorer Amerigo Vespucci (1454–1512); it was first used as a place name by the German cartographers Martin Waldseemüller and Matthias Ringmann in 1507. Vespucci first proposed that the West Indies discovered by Christopher Columbus in 1492 were part of a previously unknown landmass and not among the Indies at the eastern limit of Asia. In English, the term "America" rarely refers to topics unrelated to the United States, despite the usage of "the Americas" to describe the totality of North and South America. == History == === Indigenous peoples === The first inhabitants of North America migrated from Siberia over 12,000 years ago, either across the Bering land bridge or along the now-submerged Ice Age coastline. The Clovis culture, which appeared around 11,000 BC, is believed to be the first widespread culture in the Americas. Over time, indigenous North American cultures grew increasingly sophisticated, and some, such as the Mississippian culture, developed agriculture, architecture, and complex societies. In the post-archaic period, the Mississippian cultures were located in the midwestern, eastern, and southern regions, and the Algonquian in the Great Lakes region and along the Eastern Seaboard, while the Hohokam culture and Ancestral Puebloans inhabited the southwest. Native population estimates of what is now the United States before the arrival of European immigrants range from around 500,000 to nearly 10 million. === European exploration, colonization and conflict (1513–1765) === Christopher Columbus began exploring the Caribbean for Spain in 1492, leading to Spanish-speaking settlements and missions from Puerto Rico and Florida to New Mexico and California. The first Spanish colony in what is now the continental United States was Spanish Florida, chartered in 1513. After several settlements failed there due to hunger and disease, Spain's first permanent town, Saint Augustine, was founded in 1565. France established its own settlements in French Florida in 1562, but they were either abandoned (Charlesfort, 1578) or destroyed by Spanish raids (Fort Caroline, 1565); permanent French settlements would be founded much later along the Great Lakes (Fort Detroit, 1701), the Mississippi River (Saint Louis, 1764) and especially the Gulf of Mexico (New Orleans, 1718). Early European colonies also included the thriving Dutch colony of New Nederland (settled 1626, present-day New York) and the small Swedish colony of New Sweden (settled 1638 in what is now Delaware). British colonization of the East Coast began with the Virginia Colony (1607) and the Plymouth Colony (Massachusetts, 1620). The Mayflower Compact in Massachusetts and the Fundamental Orders of Connecticut established precedents for representative self-governance and constitutionalism that would develop throughout the American colonies. While European settlers in what is now the United States experienced conflicts with Native Americans, they also engaged in trade, exchanging European tools for food and animal pelts. Relations ranged from close cooperation to warfare and massacres. The colonial authorities often pursued policies that forced Native Americans to adopt European lifestyles, including conversion to Christianity. Along the eastern seaboard, settlers trafficked African slaves through the Atlantic slave trade. The original Thirteen Colonies that would later found the United States were administered as possessions of Great Britain, and had local governments with elections open to most white male property owners. The colonial population grew rapidly from Maine to Georgia, eclipsing Native American populations; by the 1770s, the natural increase of the population was such that only a small minority of Americans had been born overseas. The colonies' distance from Britain allowed for the development of self-governance, and the First Great Awakening, a series of Christian revivals, fueled colonial interest in religious liberty. === American Revolution and the early republic (1765–1800) === Following their victory in the French and Indian War, Britain began to assert greater control over local colonial affairs, resulting in colonial political resistance; one of the primary colonial grievances was a denial of their rights as Englishmen, particularly the right to representation in the British government that taxed them. To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association, a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in the 1775 Battles of Lexington and Concord, igniting the American Revolutionary War. At the Second Continental Congress, the colonies appointed George Washington commander-in-chief of the Continental Army, and created a committee that named Thomas Jefferson to draft the Declaration of Independence. Two days after passing the Lee Resolution to create an independent nation the Declaration was adopted on July 4, 1776. The political values of the American Revolution included liberty, inalienable individual rights; and the sovereignty of the people; supporting republicanism and rejecting monarchy, aristocracy, and all hereditary political power; civic virtue; and vilification of political corruption. The Founding Fathers of the United States, who included Washington, Jefferson, John Adams, Benjamin Franklin, Alexander Hamilton, John Jay, James Madison, Thomas Paine, and many others, were inspired by Greco-Roman, Renaissance, and Enlightenment philosophies and ideas. The Articles of Confederation and Perpetual Union were ratified in 1781 and established a decentralized government that operated until 1789. After the British surrender at the siege of Yorktown in 1781 American sovereignty was internationally recognized by the Treaty of Paris (1783), through which the U.S. gained territory stretching west to the Mississippi River, north to present-day Canada, and south to Spanish Florida. The Northwest Ordinance (1787) established the precedent by which the country's territory would expand with the admission of new states, rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances. George Washington was elected the country's first president under the Constitution, and the Bill of Rights was adopted in 1791 to allay skeptics' concerns about the power of the more centralized government. His resignation as commander-in-chief after the Revolutionary War and his later refusal to run for a third term as the country's first president established a precedent for the supremacy of civil authority in the United States and the peaceful transfer of power. === Westward expansion and Civil War (1800–1865) === The Louisiana Purchase of 1803 from France nearly doubled the territory of the United States. Lingering issues with Britain remained, leading to the War of 1812, which was fought to a draw. Spain ceded Florida and its Gulf Coast territory in 1819. In the late 18th century, American settlers began to expand westward, many with a sense of manifest destiny. The Missouri Compromise of 1820, which admitted Missouri as a slave state and Maine as a free state, attempted to balance the desire of northern states to prevent the expansion of slavery into new territories with that of southern states to extend it there. The compromise further prohibited slavery in all other lands of the Louisiana Purchase north of the 36°30′ parallel. As Americans expanded further into land inhabited by Native Americans, the federal government often applied policies of Indian removal or assimilation. The most significant removal legislation in U.S. history was the Indian Removal Act of 1830. It culminated in the Trail of Tears (1830–1850), in which an estimated 60,000 Native Americans living east of the Mississippi River were forcibly removed and displaced to lands far to the west, resulting in anywhere from 13,200 to 16,700 deaths. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas was annexed in 1845, and the 1846 Oregon Treaty led to U.S. control of the present-day American Northwest. Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest. The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of the most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies, especially in the agriculture-intensive Southern Colonies from Maryland to Georgia. The practice began to be significantly questioned during the American Revolution. Spurred by an active abolitionist movement that had reemerged in the 1830s, states in the North enacted anti-slavery laws. At the same time, support for slavery had strengthened in Southern states with inventions such as the cotton gin (1793), which had long made the institution profitable for Southern elites. Throughout the 1850s, this sectional conflict regarding slavery was further inflamed by legislation in Congress and decisions of the Supreme Court: The Fugitive Slave Act of 1850 mandated the return of slaves taking refuge in non-slave states to their owners in the South. The Kansas–Nebraska Act of 1854 effectively gutted the anti-slavery requirements of the Missouri Compromise. Finally, in its Dred Scott decision of 1857, the Supreme Court ruled against a slave brought into non-slave territory and declared the Missouri Compromise to be unconstitutional. These events exacerbated tensions between North and South that would culminate in the American Civil War (1861–1865). Eleven slave states seceded and formed the Confederate States of America, while the other states remained in the Union. War broke out in April 1861 after the Confederates bombarded Fort Sumter. After the January 1863 Emancipation Proclamation, many freed slaves joined the Union army. The war began to turn in the Union's favor following the 1863 Siege of Vicksburg and Battle of Gettysburg, and the Confederacy surrendered in 1865 after the Union's victory in the Battle of Appomattox Court House. The Reconstruction era followed the war. After the assassination of President Abraham Lincoln, Reconstruction Amendments were passed to protect the rights of African Americans. National infrastructure, including transcontinental telegraph and railroads, spurred growth in the American frontier. === Post–Civil War era (1865–1917) === From 1865 through 1917, an unprecedented stream of immigrants arrived in the United States, including 24.4 million from Europe. Most came through the port of New York City, and New York City and other large cities on the East Coast became home to large Jewish, Irish, and Italian populations, while many Germans and Central Europeans moved to the Midwest. At the same time, about one million French Canadians migrated from Quebec to New England. During the Great Migration, millions of African Americans left the rural South for urban areas in the North. Alaska was purchased from Russia in 1867. The Compromise of 1877 effectively ended Reconstruction and white supremacists took local control of Southern politics. African Americans endured a period of heightened, overt racism following Reconstruction, a time often called the nadir of American race relations. A series of Supreme Court decisions, including Plessy v. Ferguson, emptied the Fourteenth and Fifteenth Amendments of their force, allowing Jim Crow laws in the South to remain unchecked, sundown towns in the Midwest, and segregation in communities across the country, which would be reinforced by the policy of redlining later adopted by the federal Home Owners' Loan Corporation. An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries, allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by a few prominent industrialists, largely by their formation of trusts and monopolies to prevent competition. Tycoons led the nation's expansion in the railroad, petroleum, and steel industries. The United States emerged as a pioneer of the automotive industry. These changes were accompanied by significant increases in economic inequality, slum conditions, and social unrest, creating the environment for labor unions and socialist movements to begin to flourish. This period eventually ended with the advent of the Progressive Era, which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy; the islands were annexed in 1898. That same year, Puerto Rico, the Philippines, and Guam were ceded to the U.S. by Spain after the latter's defeat in the Spanish–American War. (The Philippines was granted full independence from the U.S. on July 4, 1946, following World War II. Puerto Rico and Guam have remained U.S. territories.) American Samoa was acquired by the United States in 1900 after the Second Samoan Civil War. The U.S. Virgin Islands were purchased from Denmark in 1917. === Rise as a superpower (1917–1945) === The United States entered World War I alongside the Allies, helping to turn the tide against the Central Powers. In 1920, a constitutional amendment granted nationwide women's suffrage. During the 1920s and '30s, radio for mass communication and the invention of early television transformed communications nationwide. The Wall Street Crash of 1929 triggered the Great Depression, which President Franklin D. Roosevelt responded to with the New Deal, a series of sweeping programs and public works projects combined with financial reforms and regulations. All were intended to protect against future economic depressions. Initially neutral during World War II, the U.S. began supplying war materiel to the Allies of World War II in March 1941 and entered the war in December after the Empire of Japan's attack on Pearl Harbor. The U.S. developed the first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the "Four Policemen" who met to plan the post-war world, alongside the United Kingdom, Soviet Union, and China. The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence. === Cold War (1945–1991) === After World War II, the United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs. The U.S. utilized the policy of containment to limit the USSR's sphere of influence, engaged in regime change against governments perceived to be aligned with Moscow, and prevailed in the Space Race, which culminated with the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth, urbanization, and population growth following World War II. The civil rights movement emerged, with Martin Luther King Jr. becoming a prominent leader in the early 1960s. The Great Society plan of President Lyndon B. Johnson's administration resulted in groundbreaking and broad-reaching laws, policies and a constitutional amendment to counteract some of the worst effects of lingering institutional racism. The counterculture movement in the U.S. brought significant social changes, including the liberalization of attitudes toward recreational drug use and sexuality. It also encouraged open defiance of the military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw the fall of communism and the

Along the eastern seaboard, settlers trafficked African slaves through the Atlantic slave trade. The original Thirteen Colonies that would later found the United States were administered as possessions of Great Britain, and had local governments with elections open to most white male property owners. The colonial population grew rapidly from Maine to Georgia, eclipsing Native American populations; by the 1770s, the natural increase of the population was such that only a small minority of Americans had been born overseas. The colonies' distance from Britain allowed for the development of self-governance, and the First Great Awakening, a series of Christian revivals, fueled colonial interest in religious liberty. === American Revolution and the early republic (1765–1800) === Following their victory in the French and Indian War, Britain began to assert greater control over local colonial affairs, resulting in colonial political resistance; one of the primary colonial grievances was a denial of their rights as Englishmen, particularly the right to representation in the British government that taxed them. To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association, a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in the 1775 Battles of Lexington and Concord, igniting the American Revolutionary War. At the Second Continental Congress, the colonies appointed George Washington commander-in-chief of the Continental Army, and created a committee that named Thomas Jefferson to draft the Declaration of Independence. Two days after passing the Lee Resolution to create an independent nation the Declaration was adopted on July 4, 1776. The political values of the American Revolution included liberty, inalienable individual rights; and the sovereignty of the people; supporting republicanism and rejecting monarchy, aristocracy, and all hereditary political power; civic virtue; and vilification of political corruption. The Founding Fathers of the United States, who included Washington, Jefferson, John Adams, Benjamin Franklin, Alexander Hamilton, John Jay, James Madison, Thomas Paine, and many others, were inspired by Greco-Roman, Renaissance, and Enlightenment philosophies and ideas. The Articles of Confederation and Perpetual Union were ratified in 1781 and established a decentralized government that operated until 1789. After the British surrender at the siege of Yorktown in 1781 American sovereignty was internationally recognized by the Treaty of Paris (1783), through which the U.S. gained territory stretching west to the Mississippi River, north to present-day Canada, and south to Spanish Florida. The Northwest Ordinance (1787) established the precedent by which the country's territory would expand with the admission of new states, rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances. George Washington was elected the country's first president under the Constitution, and the Bill of Rights was adopted in 1791 to allay skeptics' concerns about the power of the more centralized government. His resignation as commander-in-chief after the Revolutionary War and his later refusal to run for a third term as the country's first president established a precedent for the supremacy of civil authority in the United States and the peaceful transfer of power. === Westward expansion and Civil War (1800–1865) === The Louisiana Purchase of 1803 from France nearly doubled the territory of the United States. Lingering issues with Britain remained, leading to the War of 1812, which was fought to a draw. Spain ceded Florida and its Gulf Coast territory in 1819. In the late 18th century, American settlers began to expand westward, many with a sense of manifest destiny. The Missouri Compromise of 1820, which admitted Missouri as a slave state and Maine as a free state, attempted to balance the desire of northern states to prevent the expansion of slavery into new territories with that of southern states to extend it there. The compromise further prohibited slavery in all other lands of the Louisiana Purchase north of the 36°30′ parallel. As Americans expanded further into land inhabited by Native Americans, the federal government often applied policies of Indian removal or assimilation. The most significant removal legislation in U.S. history was the Indian Removal Act of 1830. It culminated in the Trail of Tears (1830–1850), in which an estimated 60,000 Native Americans living east of the Mississippi River were forcibly removed and displaced to lands far to the west, resulting in anywhere from 13,200 to 16,700 deaths. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas was annexed in 1845, and the 1846 Oregon Treaty led to U.S. control of the present-day American Northwest. Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest. The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of the most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies, especially in the agriculture-intensive Southern Colonies from Maryland to Georgia. The practice began to be significantly questioned during the American Revolution. Spurred by an active abolitionist movement that had reemerged in the 1830s, states in the North enacted anti-slavery laws. At the same time, support for slavery had strengthened in Southern states with inventions such as the cotton gin (1793), which had long made the institution profitable for Southern elites. Throughout the 1850s, this sectional conflict regarding slavery was further inflamed by legislation in Congress and decisions of the Supreme Court: The Fugitive Slave Act of 1850 mandated the return of slaves taking refuge in non-slave states to their owners in the South. The Kansas–Nebraska Act of 1854 effectively gutted the anti-slavery requirements of the Missouri Compromise. Finally, in its Dred Scott decision of 1857, the Supreme Court ruled against a slave brought into non-slave territory and declared the Missouri Compromise to be unconstitutional. These events exacerbated tensions between North and South that would culminate in the American Civil War (1861–1865). Eleven slave states seceded and formed the Confederate States of America, while the other states remained in the Union. War broke out in April 1861 after the Confederates bombarded Fort Sumter. After the January 1863 Emancipation Proclamation, many freed slaves joined the Union army. The war began to turn in the Union's favor following the 1863 Siege of Vicksburg and Battle of Gettysburg, and the Confederacy surrendered in 1865 after the Union's victory in the Battle of Appomattox Court House. The Reconstruction era followed the war. After the assassination of President Abraham Lincoln, Reconstruction Amendments were passed to protect the rights of African Americans. National infrastructure, including transcontinental telegraph and railroads, spurred growth in the American frontier. === Post–Civil War era (1865–1917) === From 1865 through 1917, an unprecedented stream of immigrants arrived in the United States, including 24.4 million from Europe. Most came through the port of New York City, and New York City and other large cities on the East Coast became home to large Jewish, Irish, and Italian populations, while many Germans and Central Europeans moved to the Midwest. At the same time, about one million French Canadians migrated from Quebec to New England. During the Great Migration, millions of African Americans left the rural South for urban areas in the North. Alaska was purchased from Russia in 1867. The Compromise of 1877 effectively ended Reconstruction and white supremacists took local control of Southern politics. African Americans endured a period of heightened, overt racism following Reconstruction, a time often called the nadir of American race relations. A series of Supreme Court decisions, including Plessy v. Ferguson, emptied the Fourteenth and Fifteenth Amendments of their force, allowing Jim Crow laws in the South to remain unchecked, sundown towns in the Midwest, and segregation in communities across the country, which would be reinforced by the policy of redlining later adopted by the federal Home Owners' Loan Corporation. An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries, allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by a few prominent industrialists, largely by their formation of trusts and monopolies to prevent competition. Tycoons led the nation's expansion in the railroad, petroleum, and steel industries. The United States emerged as a pioneer of the automotive industry. These changes were accompanied by significant increases in economic inequality, slum conditions, and social unrest, creating the environment for labor unions and socialist movements to begin to flourish. This period eventually ended with the advent of the Progressive Era, which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy; the islands were annexed in 1898. That same year, Puerto Rico, the Philippines, and Guam were ceded to the U.S. by Spain after the latter's defeat in the Spanish–American War. (The Philippines was granted full independence from the U.S. on July 4, 1946, following World War II. Puerto Rico and Guam have remained U.S. territories.) American Samoa was acquired by the United States in 1900 after the Second Samoan Civil War. The U.S. Virgin Islands were purchased from Denmark in 1917. === Rise as a superpower (1917–1945) === The United States entered World War I alongside the Allies, helping to turn the tide against the Central Powers. In 1920, a constitutional amendment granted nationwide women's suffrage. During the 1920s and '30s, radio for mass communication and the invention of early television transformed communications nationwide. The Wall Street Crash of 1929 triggered the Great Depression, which President Franklin D. Roosevelt responded to with the New Deal, a series of sweeping programs and public works projects combined with financial reforms and regulations. All were intended to protect against future economic depressions. Initially neutral during World War II, the U.S. began supplying war materiel to the Allies of World War II in March 1941 and entered the war in December after the Empire of Japan's attack on Pearl Harbor. The U.S. developed the first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the "Four Policemen" who met to plan the post-war world, alongside the United Kingdom, Soviet Union, and China. The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence. === Cold War (1945–1991) === After World War II, the United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs. The U.S. utilized the policy of containment to limit the USSR's sphere of influence, engaged in regime change against governments perceived to be aligned with Moscow, and prevailed in the Space Race, which culminated with the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth, urbanization, and population growth following World War II. The civil rights movement emerged, with Martin Luther King Jr. becoming a prominent leader in the early 1960s. The Great Society plan of President Lyndon B. Johnson's administration resulted in groundbreaking and broad-reaching laws, policies and a constitutional amendment to counteract some of the worst effects of lingering institutional racism. The counterculture movement in the U.S. brought significant social changes, including the liberalization of attitudes toward recreational drug use and sexuality. It also encouraged open defiance of the military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw the fall of communism and the

American football

American football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or throwing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of the game wins. American football evolved in the United States, originating from the sports of soccer and rugby. The first American football game was played on November 6, 1869, between two college teams, Rutgers and Princeton, using rules based on the rules of soccer at the time. A set of rule changes drawn up from 1880 onward by Walter Camp, the "Father of American Football", established the snap, the line of scrimmage, eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass, created the neutral zone, and specified the size and shape of the football. The sport is closely related to Canadian football, which evolved in parallel with and at the same time as the American game, although its rules were developed independently from those of Camp. Most of the features that distinguish American football from rugby and soccer are also present in Canadian football. The two sports are considered the primary variants of gridiron football. American football is the most popular sport in the United States in terms of broadcast viewership audience. The most popular forms of the game are professional and college football, with the other major levels being high-school and youth football. As of 2022, nearly 1.04 million high-school athletes play the sport in the U.S., with another 81,000 college athletes in the NCAA and the NAIA. The National Football League (NFL) has one of the highest average attendance of any professional sports league in the world. Its championship game, the Super Bowl, ranks among the most-watched club sporting events globally. In 2022, the league had an annual revenue of around $18.6 billion, making it the most valuable sports league in the world. Other professional and amateur leagues exist worldwide, but the sport does not have the international popularity of other American sports like baseball or basketball; the sport maintains a growing following in the rest of North America, Europe, Brazil, and Japan. == Etymology and names == In the United States, American football is referred to as "football". The term "football" was officially established in the rulebook for the 1876 college football season, when the sport first shifted from soccer-style rules to rugby-style rules. Although it could easily have been called "rugby" at this point, Harvard, one of the primary proponents of the rugby-style game, compromised and did not request the name of the sport be changed to "rugby". The terms "gridiron" or "American football" are favored in English-speaking countries where other types of football are popular, such as the United Kingdom, Ireland, New Zealand, and Australia. == History == === Early history === American football evolved from the sports of rugby and soccer. Rugby, like American football, is a sport in which two competing teams vie for control of a ball, which can be kicked through a set of goalposts or run into the opponent's goal area to score points. What is considered to be the first American football game was played on November 6, 1869, between Rutgers and Princeton, two college teams. They consisted of 25 players per team and used a round ball that could not be picked up or carried. It could, however, be kicked or batted with the feet, hands, head, or sides, with the objective being to advance it into the opponent's goal. Rutgers won the game 6–4. Collegiate play continued for several years with games played using the rules of the host school. Representatives of Yale, Columbia, Princeton and Rutgers met on October 19, 1873, to create a standard set of rules for use by all schools. Teams were set at 20 players each, and fields of 400 by 250 feet (122 m × 76 m) were specified. Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. After playing McGill University using both American (known as "the Boston game") for the first game and Canadian (rugby) rules for the second one, the Harvard players preferred the Canadian style of having only 11 men on the field, running the ball without having to be chased by an opponent, the forward pass, tackling, and using an oblong instead of a round ball. An 1875 Harvard–Yale game played under rugby-style rules was observed by two Princeton athletes who were impressed by it. They introduced the sport to Princeton, a feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos". Princeton, Harvard, Yale, and Columbia then agreed to intercollegiate play using a form of rugby union rules with a modified scoring system. These schools formed the Intercollegiate Football Association, although Yale did not join until 1879. Yale player Walter Camp, now regarded as the "Father of American Football", secured rule changes in 1880 that reduced the size of each team from 15 to 11 players and instituted the snap to replace the chaotic and inconsistent scrum. While the game between Rutgers and Princeton is commonly considered the first American football game, several years prior in 1862, the Oneida Football Club formed as the oldest known football club in the United States. The team consisted of graduates of Boston's elite preparatory schools and played from 1862 to 1865. === Evolution of the game === The introduction of the snap resulted in an unexpected consequence. Before the snap, the strategy had been to punt if a scrum resulted in bad field position. However, a group of Princeton players realized that, as the snap was uncontested, they could now hold the ball indefinitely to prevent their opponent from scoring. In 1881, in a game between Yale and Princeton, both teams used this strategy to maintain their undefeated records. Each team held the ball, gaining no ground, for an entire half, resulting in a 0–0 tie. This "block game" proved extremely unpopular with both teams' spectators and fans. A rule change was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered. However, Camp successfully proposed a rule in 1882 that limited each team to three downs, or tackles, to advance the ball 5 yards (4.6 m). Failure to advance the ball the required distance within those three downs would result in control of the ball being forfeited to the other team. This change effectively made American football a separate sport from rugby, and the resulting five-yard lines added to the field to measure distances made it resemble a gridiron in appearance. Other major rule changes included a reduction of the field size to 110 by 53+1⁄3 yards (100.6 m × 48.8 m) and the adoption of a scoring system that awarded four points for a touchdown, two for a safety and a goal following a touchdown, and five for a goal from the field. Additionally, tackling below the waist was legalized, and a static line of scrimmage was instituted. Despite these new rules, football remained a violent sport. Dangerous mass-formations like the flying wedge resulted in serious injuries and deaths. A 1905 peak of 19 fatalities nationwide resulted in a threat by President Theodore Roosevelt to abolish the game unless major changes were made. In response, 62 colleges and universities met in New York City to discuss rule changes on December 28, 1905. These proceedings resulted in the formation of the Intercollegiate Athletic Association of the United States, later renamed the National Collegiate Athletic Association (NCAA). The legal forward pass was introduced in 1906, although its effect was initially minimal due to the restrictions placed on its use. The idea of a 40-yard-wider field was opposed by Harvard due to the size of the new Harvard Stadium. Other rule changes introduced that year included the reduction of playing time from 70 to 60 minutes and an increase of the distance required for a first down from 5 to 10 yards (4.6 to 9.1 m). To reduce infighting and dirty play between teams, the neutral zone was created along the width of the football before the snap. Scoring was also adjusted: points awarded for field goals were reduced to three in 1909 and points for touchdowns were raised to six in 1912. Also in 1912, the field was shortened to 100 yards (91 m) long, two 10-yard-long (9.1 m) end zones were created, and teams were given four downs instead of three to advance the ball 10 yards (9.1 m). The roughing the passer penalty was implemented in 1914, and eligible players were first allowed to catch the ball anywhere on the field in 1918. === Professional era === On November 12, 1892, Pudge Heffelfinger was paid $500 (equivalent to $16,956 in 2023) to play a game for the Allegheny Athletic Association against the Pittsburgh Athletic Club. This is the first recorded instance of a player being paid to participate in a game of American football, although many athletic clubs in the 1880s offered indirect benefits, such as helping players attain employment, giving out trophies or watches that players could pawn for money, or paying double in expense money. Despite these extra benefits, the game had a strict sense of amateurism at the time, and direct payment to players was frowned upon, if not prohibited outright. Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as the illegal payment of college players who were still in school. The National Football League (NFL), a group of professional teams that was originally established in 1920 as the American Professional Football Association, aimed to solve these problems. This new league's stated goals included an end to bidding wars over players, prevention of the use of college players, and abolition of the practice of paying players to leave another team. By 1922, the NFL had established itself as America's premier professional football league. The dominant form of football at the time was played at the collegiate level. The upstart NFL received a boost to its legitimacy in 1925, however, when an NFL team, the Pottsville Maroons, defeated a team of Notre Dame all-stars in an exhibition game. A greater emphasis on the passing game helped professional football to distinguish itself further from the college game during the late 1930s. Football, in general, became increasingly popular following the 1958 NFL Championship game between the Baltimore Colts and the New York Giants, still referred to as the "Greatest Game Ever Played". The game, a 23–17 overtime victory by the Colts, was seen by millions of television viewers and had a major influence on the popularity of the sport. This, along with the innovations introduced by the new American Football League (AFL) in the early 1960s, helped football to become the most popular sport in the United States by the mid-1960s. The rival AFL arose in 1960 and challenged the NFL's dominance. The AFL began in relative obscurity but eventually thrived, with an initial television contract with the ABC television network. The AFL's existence forced the conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league. Meanwhile, the AFL introduced many new features to professional football in the United States: official time was kept on a scoreboard clock rather than on a watch in the referee's pocket, as the NFL did; optional two-point conversions by pass or run after touchdowns; names on the jerseys of players; and several others, including expansion of the role of minority players, actively recruited by the league in contrast to the NFL. The AFL also signed several star college players who had also been drafted by NFL teams. Competition for players heated up in 1965, when the AFL New York Jets signed rookie Joe Namath to a then-record $437,000 contract (equivalent to $4.23 million in 2023). A five-year, $40 million NBC television contract followed, which helped to sustain the young league. The bidding war for players ended in 1966 when NFL owners approached the AFL regarding a merger, and the two leagues agreed on one that took full effect in 1970. This agreement provided for a common draft that would take place each year, and it instituted an annual World Championship game to be played between the champions of each league. This championship game began play at the end of the 1966 season. Once the merger was completed, it was no longer a championship game between two leagues and reverted to the NFL championship game, which came to be known as the Super Bowl. College football maintained a tradition of postseason bowl games. Each bowl game was associated with a particular conference and earning a spot in a bowl game was the reward for winning a conference. This arrangement was profitable, but it tended to prevent the two top-ranked teams from meeting in a true national championship game, as they would normally be committed to the bowl games of their respective conferences. Several systems have been used since 1992 to determine a national champion of college football. The first was the Bowl Coalition, in place from 1992 to 1994. This was replaced in 1995 by the Bowl Alliance, which gave way to the Bowl Championship Series (BCS) in 1997. The BCS arrangement proved to be controversial, and was replaced in 2014 by the College Football Playoff (CFP). == Teams and positions == A football game is played between two teams of 11 players each. Playing with more on the field is punishable by a penalty. Teams may substitute any number of their players between downs; this "platoon" system replaced the original system, which featured limited substitution rules, and has resulted in teams utilizing specialized offensive, defensive and special teams units. The number of players allowed on an active roster varies by league; the NFL has a 53-man roster, while NCAA Division I allows teams to have 63 scholarship players in the FCS and 85 scholarship players in the FBS, respectively. Individual players in a football game must be designated with a uniform number between 0 and 99, though some teams may "retire" certain numbers, making them unavailable to players. NFL teams are required to number their players by a league-approved numbering system, and any exceptions must be approved by the commissioner. NCAA and NFHS teams are "strongly advised" to number their offensive players according to a league-suggested numbering scheme. Although the sport is played almost exclusively by men, women are eligible to play in high school, college, and professional football. No woman has ever played in the NFL, but women have played in high school and college football games. In 2018, 1,100 of the 225,000 players in Pop Warner Little Scholars youth football were girls, and around 11% of the 5.5 million Americans who report playing tackle football are female according to the Sports and Fitness Industry Association. === Offensive unit === The role of the offensive unit is to advance the football down the field with the ultimate goal of scoring a touchdown. The offensive team must line up in a legal formation before they can snap the ball. An offensive formation is considered illegal if there are more than four players in the backfield or fewer than five players numbered 50–79 on the offensive line. Players can line up temporarily in a position whose eligibility is different from what their number permits as long as they report the change immediately to the referee, who then informs the defensive team of the change. Neither team's players, except the center (C), are allowed to line up in or cross the neutral zone until the ball is snapped. Interior offensive linemen are not allowed to move until the snap of the ball. The main backfield positions are the quarterback (QB), halfback/tailback (HB/TB), and fullback (FB). The quarterback is the leader of the offense. Either the quarterback or a coach calls the plays. Quarterbacks typically inform the rest of the offense of the play in the huddle before the team lines up. The quarterback lines up behind the center to take the snap and then hands the ball off, throws it, or runs with it. The primary role of the halfback, also known as the running back or tailback, is to carry the ball on running plays. Halfbacks may also serve as receivers. Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage or goal-line situations. They are seldom used as receivers. The offensive line (OL) consists of several players whose primary function is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays. The leader of the offensive line is the center, who is responsible for snapping the ball to the quarterback, blocking, and for making sure that the other linemen do their jobs during the play. On either side of the center are the guards (G), while tackles (T) line up outside the guards. The principal receivers are the wide receivers (WR) and the tight ends (TE). Wide receivers line up on or near the line of scrimmage, split outside the line. The main goal of the wide receiver is to catch passes thrown by the quarterback, but they may also function as decoys or as blockers during running plays. Tight ends line up outside the tackles and function both as receivers and as blockers. === Defensive unit === The role of the defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers. Turnovers include interceptions (a defender catching a forward pass intended for the offense) and forced fumbles (taking possession of the ball from the ball-carrier). The defensive line (DL) consists of defensive ends (DE) and defensive tackles (DT). Defensive ends line up on the ends of the line, while defensive tackles line up inside, between the defensive ends. The primary responsibilities of defensive ends and defensive tackles are to stop running plays on the outside and inside, respectively, to pressure the quarterback on passing plays, and to occupy the line so that the linebackers can break through. Linebackers line up behind the defensive line but in front of the defensive backfield. They are divided into two types: middle linebackers (MLB) and outside linebackers (OLB). Linebackers tend to serve as the defensive leaders and call the defensive plays, given their vantage point of the offensive backfield. Their roles include defending the run, pressuring the quarterback, and tackling backs, wide receivers, and tight ends in the passing game. The defensive backfield, often called the secondary, consists of cornerbacks (CB) and safeties (S). Safeties are themselves divided into free safeties (FS) and strong safeties (SS). Cornerbacks line up outside the defensive formation, typically opposite a receiver to be able to cover them. Safeties line up between the cornerbacks but farther back in the secondary. Safeties tend to be viewed as "the last line of defense" and are responsible for stopping deep passing plays as well as breakout running plays. === Special teams unit === The special teams unit is responsible for all kicking plays. The special teams unit of the team in control of the ball tries to execute field goal (FG) attempts, punts, and kickoffs, while the opposing team's unit will aim to block or return them. Three positions are specific to the field goal and PAT (point-after-touchdown) unit: the placekicker (K or PK), holder (H), and long snapper (LS). The long snapper's job is to snap the football to the holder, who will catch and position it for the placekicker. There is not usually a holder on kickoffs, because the ball is kicked off a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee. The player on the receiving team who catches the ball is known as the kickoff returner (KR). The positions specific to punt plays are the punter (P), long snapper, upback, and gunner. The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground. Gunners line up split outside the line and race down the field, aiming to tackle the punt returner (PR)—the player who catches the punt. Upbacks line up a short distance behind the line of scrimmage, providing additional protection to the punter. == Rules == === Scoring === In football, the winner is the team that has scored more points at the end of the game. There are multiple ways to score in a football game. The touchdown (TD), worth six points, is the most valuable scoring play in American football. A touchdown is scored when a live ball is advanced into, caught, or recovered in the opposing team's end zone. The scoring team then attempts a try, more commonly known as the point(s)-after-touchdown (PAT) or conversion, which is a single scoring opportunity. This is generally attempted from the two- or three-yard line, depending on the level of play. If the PAT is scored by a place kick or drop kick through the goal posts, it is worth one point, typically called the extra point. If the PAT is scored by what would normally be a touchdown, it is worth two points; this is known as a two-point conversion. In general, the extra point is almost always successful, while the two-point conversion is a much

North America

North America is a continent in the Northern and Western Hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. The region includes the Bahamas, Bermuda, Canada, the Caribbean, Central America, Clipperton Island, Greenland, Mexico, Saint Pierre and Miquelon, the Turks and Caicos Islands, and the United States. North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of the Earth's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa, and the fourth-largest continent by population after Asia, Africa, and Europe. As of 2021, North America's population was estimated as over 592 million people in 23 independent states, or about 7.5% of the world's population. In human geography, the terms "North America" and "North American" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as a part of Denmark) and Mexico classified as Latin American). It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when the Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America. In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange, including migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, enslaved Africans, immigrants from Europe, Asia, and descendants of these respective groups. Europe's colonization in North America led to most North Americans speaking European languages, such as English, Spanish, and French, and the cultures of the region commonly reflect Western traditions. However, relatively small parts of North America in Canada, the United States, Mexico, and Central America have indigenous populations that continue adhering to their respective pre-European colonial cultural and linguistic traditions. == Name == The Americas were named after the Italian explorer Amerigo Vespucci by German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci explored South America between 1497 and 1502, and was the first European to suggest that the Americas represented a landmass then unknown to the Europeans. In 1507, Waldseemüller published a world map, and placed the word "America" on the continent of present-day South America. The continent north of present-day Mexico was then referred to as Parias. On a 1553 world map published by Petrus Apianus, North America was called "Baccalearum", meaning "realm of the Cod fish", in reference to the abundance of cod on the East Coast. Waldseemüller used the Latinized version of Vespucci's name, Americus Vespucius, in its feminine form of "America", following the examples of "Europa", "Asia", and "Africa". Americus originated from Medieval Latin Emericus (see Saint Emeric of Hungary), coming from the Old High German name Emmerich. Map makers later extended the name America to North America. In 1538, Gerardus Mercator used the term America on his world map of the entire Western Hemisphere. On his subsequent 1569 map, Mercator called North America "America or New India" (America sive India Nova). The Spanish Empire called its territories in North and South America "Las Indias", and the name given to the state body that oversaw the region was called the Council of the Indies. == Definitions == The United Nations and its statistics division recognize North America as including three regions: Northern America, Central America, and the Caribbean. "Northern America" is a term distinct from "North America", excluding Central America, which itself may or may not include Mexico. In the limited context of regional trade agreements, the term is used to reference three nations: Canada, the United States, and Mexico. France, Italy, Portugal, Spain, Romania, Greece, and the countries of Latin America use a six-continent model, with the Americas viewed as a single continent and North America designating a subcontinent comprising Canada, the United States, Mexico, and Saint Pierre and Miquelon (politically part of France), and often Greenland and Bermuda. North America has historically been known by other names, including Spanish North America, New Spain, and América Septentrional, the first official name given to Mexico. === Regions === North America includes several regions and subregions, each of which have their own respective cultural, economic, and geographic regions. Economic regions include several regions formalized in 20th- and 21st-century trade agreements, including NAFTA between Canada, Mexico, and the United States, and CAFTA between Central America, the Dominican Republic, and the United States. North America is divided linguistically and culturally into two primary regions, Anglo-America and Latin America. Anglo-America includes most of North America, Belize, and Caribbean islands with English-speaking populations. There are also regions, including Louisiana and Quebec, with large Francophone populations; in Quebec, French is the official language.. The southern portion of North America includes Central America and non-English-speaking Caribbean nations. The north of the continent maintains recognized regions as well. In contrast to the common definition of North America, which encompasses the whole North American continent, the term "North America" is sometimes used more narrowly to refer only to four nations, Canada, Greenland, Mexico, and the U.S. The U.S. Census Bureau includes Saint Pierre and Miquelon, but excludes Mexico from its definition. The term Northern America refers to the northernmost countries and territories of North America: the U.S., Bermuda, Canada, Greenland, and St. Pierre and Miquelon. Although the term does not refer to a unified region, Middle America includes Mexico, Central America, and the Caribbean. North America's largest countries by land area are Canada and the U.S., both of which have well-defined and recognized subregions. In Canada, these include (from east to west) Atlantic Canada, Central Canada, the Canadian Prairies, the British Columbia Coast, Western Canada, and Northern Canada. In the U.S., they include New England, the Mid-Atlantic, and the South Atlantic, East North Central, West North Central, East South Central, West South Central, Mountain, and Pacific states. The Great Lakes region and the Pacific Northwest include areas in both the U.S. and Canada. === Countries, dependencies, and other territories === == Geography == North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America, which, in many countries, is considered a single continent with North America a subcontinent. North America is the third-largest continent by area after Asia and Africa. North America's only land connection to South America is in present-day Panama at the Darien Gap on the Colombia–Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec, Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California. Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge, which had connected North and South America via what are now Florida and Venezuela. There are several islands off the continent's coasts; principally, the Arctic Archipelago, the Bahamas, Turks and Caicos, the Greater and Lesser Antilles, the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago, the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland, a self-governing Danish island, and the world's largest, is on the same tectonic plate (the North American Plate) and is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago (mya). The nearest landmass to it is Cape Hatteras, North Carolina. However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of the continent. The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California, including the cities of San Diego, Los Angeles, and Santa Cruz, lie on the eastern edge of the Pacific Plate, with the two plates meeting along the San Andreas Fault. The southernmost portion of the continent and much of the West Indies lie on the Caribbean Plate, whereas the Juan de Fuca Plate and Cocos Plate border the North American Plate on its western frontier. The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic; the geologically young, mountainous west, including the Rocky Mountains, the Great Basin, California, and Alaska; the raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras, falls largely in the western region, although the eastern coastal plain does extend south along the Gulf. The western mountains are split in the middle into the main range of the Rockies and the coast ranges in California, Oregon, Washington, and British Columbia, with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali in Alaska. The U.S. Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota" at about 48°10′N 100°10′W, about 24 kilometers (15 mi) from Rugby, North Dakota. The USGS further states that "No marked or monumented point has been established by any government agency as the geographic center of either the 50 states, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-meter (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43.36°N 101.97°W / 43.36; -101.97 (Pole of Inaccessibility North America). === Canada === Canada can be divided into roughly seven physiographic divisions: The Canadian Shield The interior plains The Great Lakes-St. Lawrence Lowlands The Appalachian region The Western Cordillera Hudson Bay Lowlands Arctic Archipelago === United States === The lower 48 U.S. states can be divided into roughly eight physiographic divisions: The Intermontane Plateaus The Laurentian Upland, part of the Canadian Shield Northern portion of the upper midwestern U.S. The Interior Plains The Atlantic Plain The Appalachian highlands The Interior highlands The Rocky Mountain system The Pacific Mountain system === Mexico === Mexico can be divided into roughly fifteen physiographic divisions: The Baja California Peninsula The Sonoran Basin and Range The Western Sierra Madre The Northern Mountains and Plains The Eastern Sierra Madre The Great Plain The Pacific Coastal Plain The Northern Gulf Coast Plain The Central Plateau The Volcanic Axis The Southern Sierra Madre The Southern Gulf Coast Plain The Chiapas Sierra Madre The Chiapas Highlands The Yucatán Peninsula === Climate === North America is a very large continent that extends from north of the Arctic Circle to south of the Tropic of Cancer. Greenland, along with the Canadian Shield, is tundra with average temperatures ranging from 10 to 20 °C (50 to 68 °F), but central Greenland is composed of a very large ice sheet. This tundra radiates throughout Canada, but its border ends near the Rocky Mountains (but still contains Alaska) and at the end of the Canadian Shield, near the Great Lakes. Climate west of the Cascade Range is described as being temperate weather with average precipitation 20 inches (510 millimeters). Climate in coastal California is described to be Mediterranean, with average temperatures in cities like San Francisco ranging from 57 to 70 °F (14 to 21 °C) over the course of the year. Stretching from the East Coast to eastern North Dakota, and stretching down to Kansas, is the humid continental climate featuring intense seasons, with a large amount of annual precipitation, with places like New York City averaging 50 in (1,300 mm). Starting at the southern border of the humid continental climate and stretching to the Gulf of Mexico (while encompassing the eastern half of Texas) is the humid subtropical climate. This area has the wettest cities in the contiguous U.S., with annual precipitation reaching 67 in (1,700 mm) in Mobile, Alabama. Stretching from the borders of the humid continental and subtropical climates, and going west to the Sierra Nevada, south to the southern tip of Durango, north to the border with tundra climate, the steppe/desert climates are the driest in the U.S. Highland climates cut from north to south of the continent, where subtropical or temperate climates occur just below the tropics, as in central Mexico and Guatemala. Tropical climates appear in the island regions and in the subcontinent's bottleneck, found in countries and states bathed by the Caribbean Sea or to the south of the Gulf of Mexico and the Pacific Ocean. Precipitation patterns vary across the region, and as such rainforest, monsoon, and savanna types can be found, with rains and high temperatures throughout the year. === Ecology === Notable North American fauna include the bison, black bear, jaguar, cougar, prairie dog, turkey, pronghorn, raccoon, coyote, and monarch butterfly. Notable plants that were domesticated in North America include tobacco, maize, squash, tomato, sunflower, blueberry, avocado, cotton, chile pepper, and vanilla. == Geology == === Geologic history === Laurentia is an ancient craton which forms the geologic core of North America; it formed between 1.5 and 1.0 billion years ago during the Proterozoic eon. The Canadian Shield is the largest exposure of this craton. From the Late Paleozoic to Early Mesozoic eras, North America was joined with the other modern-day continents as part of the supercontinent Pangaea, with Eurasia to its east. One of the results of the formation of Pangaea was the Appalachian Mountains, which formed some 480 mya, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 mya, North America became part of Laurasia, before it separated from Eurasia as its own continent during the mid-Cretaceous period. The Rockies and other western mountain ranges began forming around this time from a period of mountain building called the Laramide orogeny, between 80 and 55 mya. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 mya, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago. North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become the United States has been the source of more varieties of dinosaurs than any other modern country. According to paleontologist Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history. Much of the Mesozoic Era is represented by exposed outcrops in the many arid regions of the continent. The most significant Late Jurassic dinosaur-bearing fossil deposit in North America is the Morrison Formation of the western U.S. === Canada === Canada is geologically one of the oldest regions in the world, with more than half of the region consisting of Precambrian rocks that have been above sea level since the beginning of the Palaeozoic era. Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc, copper, gold, lead, molybdenum, and uranium reserves. Large diamond concentrations have been recently developed in the Arctic, making Canada one of the world's largest producers. Throughout the Shield, there are many mining towns extracting these minerals. The largest, and best known, is Sudbury, Ontario. Sudbury is an exception to the normal process of forming minerals in the Shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater. The nearby, but less-known Temagami Magnetic Anomaly has striking similarities to the Sudbury Basin. Its magnetic anomalies are very similar to the Sudbury Basin, and so it could be a second metal-rich impact crater. The Shield is also covered by vast boreal forests that support an important logging industry. === United States === The United States can be divided into twelve main geological provinces: Pacific Columbia Plateau Basin and Range Colorado Plateau Rocky Mountains Laurentian Upland Interior Plains Interior Highlands Appalachian Highlands Atlantic Plain Alaskan Hawaiian Each province has its own geologic history and unique features. The geology of Alaska is typical of that of the cordillera, while the major islands of Hawaii consist of Neogene volcanics erupted over a hot spot. === Central America === Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake, killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras a powerful earthquake killed seven people in 2009. Volcanic eruptions are common in the region. In 1968, the Arenal Volcano, in Costa Rica, erupted and killed 87 people. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas. Central America has many mountain ranges; the longest are the Sierra Madre de Chiapas, the Cordillera Isabelia, and the Cordillera de Talamanca. Between the mountain ranges lie fertile valleys that are suitable for the people; in fact, most of the population of Honduras, Costa Rica, and Guatemala live in valleys. Valleys are also suitable for the production of coffee, beans, and other crops. == History == === Pre-Columbian era === The indigenous peoples of the Americas have many creation myths, based on which they assert that they have been present on the land since its creation, but there is no evidence that humans evolved there. The specifics of the initial settlement of the Americas by ancient Asians are subject to ongoing research and discussion. The traditional theory has been that hunters entered the Bering Land Bridge between eastern Siberia and present-day Alaska from 27,000 to 14,000 years ago. A growing viewpoint is that the first American inhabitants sailed from Beringia some 13,000 years ago, with widespread habitation of the Americas during the end of the Last Glacial Period, in what is known as the Late Glacial Maximum, around 12,500 years ago. The oldest petroglyphs in North America date from 15,000 to 10,000 years before present. Genetic research and anthropology indicate additional waves of migration from Asia via the Bering Strait during the Early-Middle Holocene. Prior to the arrival of European explorers and colonists in North America, the natives of North America were divided into many different polities, ranging from small bands of a few families to large empires. They lived in several culture areas, which roughly correspond to geographic and biological zones that defined the representative cultures and lifestyles of the indigenous people who lived there, including the bison hunters of the Great Plains and the farmers of Mesoamerica. Native groups also are classified by their language families, which included Athabaskan and Uto-Aztecan languages. Indigenous peoples with similar languages did not always share the same material culture, however, and were not necessarily always allies. Anthropologists speculate that the Inuit of the high Arctic arrived in North America much later than other native groups, evidenced by the disappearance of Dorset culture artifacts from the archaeological record and their replacement by the Thule people. During the thousands of years of native habitation on the continent, cultures changed and shifted. One of the oldest yet discovered is the Clovis culture (c. 9550–9050 BCE) in modern New Mexico. Later groups include the Mississippian cultur

Americas

The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America. When viewed as a single continent, the Americas or America is the 2nd largest continent right after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes, Mississippi, and La Plata basins. Since the Americas extend 14,000 km (8,700 mi) from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rainforests in Central America and South America. Humans first settled the Americas from Asia between 20,000 and 16,000 years ago. A second migration of Na-Dene speakers followed later from Asia. The subsequent migration of the Inuit into the neoarctic c. 3500 BCE completed what is generally regarded as the settlement by the Indigenous peoples of the Americas. The first known European settlement in the Americas was by the Norse explorer Leif Erikson. However, the colonization never became permanent and was later abandoned. The Spanish voyages of Christopher Columbus from 1492 to 1504 resulted in permanent contact with European (and subsequently, other Old World) powers, which eventually led to the Columbian exchange and inaugurated a period of exploration, conquest, and colonization whose effects and consequences persist to the present. The Spanish presence involved the enslavement of large numbers of the indigenous population of America. Diseases introduced from Europe and West Africa devastated the indigenous peoples, and the European powers colonized the Americas. Mass emigration from Europe, including large numbers of indentured servants, and importation of African slaves largely replaced the indigenous peoples in much of the Americas. Decolonization of the Americas began with the American Revolution in the 1770s and largely ended with the Spanish–American War in the late 1890s. Currently, almost all of the population of the Americas resides in independent countries; however, the legacy of the colonization and settlement by Europeans is that the Americas share many common cultural traits, most notably Christianity and the use of West European languages: primarily Spanish, English, Portuguese, French, and, to a lesser extent, Dutch. The Americas are home to more than a billion inhabitants, two-thirds of whom reside in the United States, Brazil, and Mexico. It is home to eight megacities (metropolitan areas with 10 million inhabitants or more): Greater Mexico City (21.2 million), São Paulo (21.2 million), New York City (19.7 million), Los Angeles (18.8 million), Buenos Aires (15.6 million), Rio de Janeiro (13.0 million), Bogotá (10.4 million), and Lima (10.1 million). == Etymology and naming == The name "America" was first recorded in 1507. A two-dimensional globe created by Martin Waldseemüller was the earliest recorded use of the term. The name was also used (together with the related term Amerigen) in the Cosmographiae Introductio, apparently written by Matthias Ringmann, in reference to South America. It was applied to both North and South America by Gerardus Mercator in 1538. "America" derives from Americus, the Latin version of Italian explorer Amerigo Vespucci's first name. The feminine form America was originally used to refer to the newly discovered continent, which is why it was accorded with the feminine names of the other continents: Asia, Africa, and Europa. Since the 1950s, however, North America and South America have generally been considered by English speakers as separate continents, and taken together are called the Americas, or more rarely America. When conceived as a unitary continent, the form is generally the continent of America in the singular. However, without a clarifying context, singular America in English commonly refers to the United States of America. == History == === Pre-Columbian era === The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic to European colonization during the Early Modern period. The term Pre-Columbian is used especially often in the context of the great indigenous civilizations of the Americas, such as those of Mesoamerica (Olmec, Toltec, Teotihuacano, Zapotec, Mixtec, Aztec, Maya) and the Andean civilizations (Inca, Moche, Chavín, Muisca, Cañari). Many pre-Columbian civilizations established characteristics and hallmarks which included permanent or urban settlements, agriculture, civic and monumental architecture, and complex societal hierarchies. Some of these civilizations had long faded by the time of the first permanent European arrivals (c. late 15th–early 16th centuries), and are known only through archeological investigations. Others were contemporary with this period, and are also known from historical accounts of the time. A few, such as the Maya, had their own written records. However, most Europeans of the time viewed such texts as pagan, and much was destroyed in Christian pyres. Only a few hidden documents remain today, leaving modern historians with glimpses of ancient culture and knowledge. ==== Settlement ==== The first inhabitants migrated into the Americas from Asia. Habitation sites are known in Alaska and Yukon from at least 20,000 years ago, with suggested ages of up to 40,000 years. Beyond that, the specifics of the Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are subject to ongoing research and discussion. Widespread habitation of the Americas occurred after the Late Glacial Maximum, from 16,000 to 13,000 years ago. The traditional theory has been that these early migrants moved into the Beringia land bridge between eastern Siberia and present-day Alaska around 40,000–17,000 years ago, when sea levels were significantly lowered during the Quaternary glaciation. These people are believed to have followed herds of now-extinct pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America. Evidence of the latter would since have been covered by a sea level rise of hundreds of meters following the last ice age. Both routes may have been taken, although the genetic evidences suggests a single founding population. The micro-satellite diversity and distributions specific to South American Indigenous peoples indicates that certain populations have been isolated since the initial colonization of the region. A second migration occurred after the initial peopling of the Americas; Na Dene speakers found predominantly in North American groups at varying genetic rates with the highest frequency found among the Athabaskans at 42% derive from this second wave. Linguists and biologists have reached a similar conclusion based on analysis of Amerindian language groups and ABO blood group system distributions. Then the people of the Arctic small tool tradition, a broad cultural entity that developed along the Alaska Peninsula, around Bristol Bay, and on the eastern shores of the Bering Strait c. 2500 BCE moved into North America. The Arctic small tool tradition, a Paleo-Eskimo culture branched off into two cultural variants, including the Pre-Dorset, and the Independence traditions of Greenland. The descendants of the Pre-Dorset cultural group, the Dorset culture was displaced by the final migrants from the Bering sea coast line, the Thule people (the ancestors of modern Inuit), by 1000 CE. ==== Norse colonization ==== Around the same time as the Inuit migrated into Greenland, Viking settlers began arriving in Greenland in 982 and Vinland shortly thereafter, establishing a settlement at L'Anse aux Meadows, near the northernmost tip of Newfoundland. Contact between the Norse colonies and Europe was maintained, as James Watson Curran states:From 985 to 1410, Greenland was in touch with the world. Then silence. In 1492 the Vatican noted that no news of that country "at the end of the world" had been received for 80 years, and the bishopric of the colony was offered to a certain ecclesiastic if he would go and "restore Christianity" there. He didn't go. === Large-scale European colonization === Although there had been previous trans-oceanic contact, large-scale European colonization of the Americas began with the first voyage of Christopher Columbus in 1492. The first Spanish settlement in the Americas was La Isabela in northern Hispaniola. This town was abandoned shortly after in favor of Santo Domingo de Guzmán, founded in 1496, the oldest American city of European foundation. This was the base from which the Spanish monarchy administered its new colonies and their expansion. Santo Domingo was subject to frequent raids by English and French pirates. On the continent, Panama City on the Pacific coast of Central America, founded on August 15, 1519, played an important role, being the base for the Spanish conquest of South America. Conquistador Lucas Vázquez de Ayllón established San Miguel de Guadalupe, the first European settlement in what is now the United States, on the Pee Dee River in South Carolina. During the first half of the 16th century, Spanish colonists conducted raids throughout the Caribbean Basin, bringing captives from Central America, northern South America, and Florida back to Hispaniola and other Spanish settlements. France, led by Jacques Cartier and Giovanni da Verrazzano, focused primarily on North America. English explorations of the Americas were led by Giovanni Caboto and Sir Walter Raleigh. The Dutch in New Netherland confined their operations to Manhattan Island, Long Island, the Hudson River Valley, and what later became New Jersey. The spread of new diseases brought by Europeans and African slaves killed many of the inhabitants of North America and South America, with a general population crash of Native Americans occurring in the mid-16th century, often well ahead of European contact. One of the most devastating diseases was smallpox. European immigrants were often part of state-sponsored attempts to found colonies in the Americas. Migration continued as people moved to the Americas fleeing religious persecution or seeking economic opportunities. Millions of individuals were forcibly transported to the Americas as slaves, prisoners or indentured servants. Decolonization of the Americas began with the American Revolution and the Haitian Revolution in the late 1700s. This was followed by numerous Latin American wars of independence in the early 1800s. Between 1811 and 1825, Paraguay, Argentina, Chile, Gran Colombia, the United Provinces of Central America, Mexico, Brazil, Peru, and Bolivia gained independence from Spain and Portugal in armed revolutions. After the Dominican Republic won independence from Haiti, it was re-annexed by Spain in 1861, but reclaimed its independence in 1865 at the conclusion of the Dominican Restoration War. The last violent episode of decolonization was the Cuban War of Independence which became the Spanish–American War, which resulted in the independence of Cuba in 1898, and the transfer of sovereignty over Puerto Rico from Spain to the United States. Peaceful decolonization began with the United States's purchase of Louisiana from France in 1803, Florida from Spain in 1819, of Alaska from Russia in 1867, and the Danish West Indies from Denmark in 1916. Canada became independent of the United Kingdom, starting with the Balfour Declaration of 1926, Statute of Westminster 1931, and ending with the patriation of the Canadian Constitution in 1982. The Dominion of Newfoundland similarly achieved independence under the Balfour Declaration and Statute of Westminster, but relinquished self-rule in 1934. It was subsequently confederated with Canada in 1949. The remaining European colonies in the Caribbean began to achieve peaceful independence well after World War II. Jamaica and Trinidad and Tobago became independent in 1962, and Guyana and Barbados both achieved independence in 1966. In the 1970s, the Bahamas, Grenada, Dominica, St. Lucia, and St. Vincent and the Grenadines all became independent of the United Kingdom, and Suriname became independent of the Netherlands. Belize, Antigua and Barbuda, and Saint Kitts and Nevis achieved independence from the United Kingdom in the 1980s. == Geography == === Extent === The Americas make up most of the land in Earth's Western Hemisphere. The northernmost point of the Americas is Kaffeklubben Island, which is the most northerly point of land on Earth. The southernmost undisputed point is Águila Islet, although the Antarctic islands of Southern Thule are sometimes taken into account. The mainland of the Americas is the world's longest north-to-south landmass. The distance between its two polar extremities, Murchison Promontory on the Boothia Peninsula in northern Canada and Cape Froward in Chilean Patagonia, is roughly 14,000 km (8,700 mi). The mainland's most westerly point is the end of the Seward Peninsula in Alaska; Attu Island, further off the Alaskan coast to the west, is considered the westernmost point of the Americas. Ponta do Seixas in northeastern Brazil forms the easternmost extremity of the mainland, while Nordostrundingen, in Greenland, is the most easterly point of the continental shelf. === Geology === South America broke off from the west of the supercontinent Gondwana around 135 million years ago, forming its own continent. Around 15 million years ago, the collision of the Caribbean Plate and the Pacific Plate resulted in the emergence of a series of volcanoes along the border that created a number of islands. The gaps in the archipelago of Central America filled in with material eroded off North America and South America, plus new land created by continued volcanism. By three million years ago, the continents of North America and South America were linked by the Isthmus of Panama, thereby forming the single landmass of the Americas. The Great American Interchange resulted in many species being spread across the Americas, such as the cougar, porcupine, opossums, armadillos, and hummingbirds. === Topography === The geography of the western Americas is dominated by the American Cordillera, with the Andes running along the west coast of South America and the Rocky Mountains and other North American Cordillera ranges running along the western side of North America. The 2,300-kilometer-long (1,400 mi) Appalachian Mountains run along the east coast of North America from Alabama to Newfoundland. North of the Appalachians, the Arctic Cordillera runs along the eastern coast of Canada. The largest mountain ranges are the Andes and Rocky Mountains. The Sierra Nevada and the Cascade Range reach similar altitudes as the Rocky Mountains, but are significantly smaller. In North America, the greatest number of fourteeners are in the United States, and more specifically in the US state of Colorado. The highest peaks of the Americas are located in the Andes, with Aconcagua of Argentina being the highest; in North America Denali (Mount McKinley) in the US state of Alaska is the tallest. Between its coastal mountain ranges, North America has vast flat areas. The Interior Plains spread over much of the continent, with low relief. The Canadian Shield covers almost 5 million km2 of North America and is generally quite flat. Similarly, the north-east of South America is covered by the flat Amazon basin. The Brazilian Highlands on the east coast are fairly smooth but show some variations in landform, while farther south the Gran Chaco and Pampas are broad lowlands. === Climate === The climate of the Americas varies significantly from region to region. Tropical rainforest climate occurs in the latitudes of the Amazon, American cloud forests, southeastern Florida and Darién Gap. In the Rocky Mountains and Andes, dry and continental climates are observed. Often the higher altitudes of these mountains are snow-capped. Southeastern North America is well known for its occurrence of tornadoes and hurricanes, of which the vast majority of tornadoes occur in the United States' Tornado Alley, as well as in the southerly Dixie Alley in the North American late-winter and early spring seasons. Often parts of the Caribbean are exposed to the violent effects of hurricanes. These weather systems are formed by the collision of dry, cool air from Canada and wet, warm air from the Atlantic. === Hydrology === With coastal mountains and interior plains, the Americas have several large river basins that drain the continents. The largest river basin in North America is that of the Mississippi, covering the second-largest watershed on the planet. The Mississippi–Missouri river system drains most of 31 states of the United States, most of the Great Plains, and large areas between the Rocky and Appalachian mountains. The Mississippi–Missouri is the fourth-longest river system and has the tenth-greatest discharge in the world. In North America, to the east of the Appalachian Mountains, there are no major rivers but rather a series of rivers and streams that flow east with their terminus in the Atlantic Ocean, such as the Hudson, Saint John, and Savannah rivers. A similar instance arises with central Canadian rivers that drain into Hudson Bay; the largest being the Churchill River. On the west coast of North America, the main rivers are the Colorado, Columbia, Yukon, Fraser, and Sacramento rivers. The Colorado River drains much of the Southern Rockies and parts of the Basin and Range Province. The river flows approximately 1,450 miles (2,330 km) into the Gulf of California, during which over time it has carved out natural phenomena such as the Grand Canyon and created phenomena such as the Salton Sea. The Columbia is a large river, 1,243 miles (2,000 km) long, in central western North America and is the most powerful river on the West Coast of the Americas. In the far northwest of North America, the Yukon drains much of the Alaskan peninsula and flows 1,980 miles (3,190 km) from parts of Yukon and the Northwest Territory to the Pacific. Draining to the Arctic Ocean of Canada, the Mackenzie River drains waters from the Arctic Great Lakes of Arctic Canada, as opposed to the St Lawrence River that drains the Great Lakes of southern Canada into the Atlantic Ocean. The Mackenzie River is the largest in Canada and drains 1,805,200 km2 (697,000 sq mi). The largest river basin in South America is that of the Amazon, which has the highest volume flow of any river on Earth. The second largest watershed of South America is that of the Paraná River, which covers about 2,582,074 km2 (996,944 sq mi). === Ecology === North America and South America began to develop a shared population of flora and fauna around 2.5 million years ago, when continental drift brought the two continents into contact via the Isthmus of Panama. Initially, the exchange of biota was roughly equal, with North American genera migrating into South America in about the same proportions as South American genera migrated into North America. This exchange is known as the Great American Interchange. The exchange became lopsided after roughly a million years, with the total spread of South American genera into North America far more limited in scope than the spread of North American genera into South America. == Countries and territories == There are 35 sovereign states in the Americas, as well as an autonomous country of Denmark, three overseas departments of France, three overseas collectivities of France, and one uninhabited territory of France, eight overseas territories of the United Kingdom, three constituent countries of the Netherlands, three public bodies of the Netherlands, two unincorporated territories of the United States, and one uninhabited territory of the United States. == Demography == === Population === In 2021 the total population of the Americas was about 1.03 billion people, divided as follows: North America: 596.6 million (includes Central America and the Caribbean) South America: 434.3 million === Largest urban centers === There are three urban centers that each hold titles for being the largest population area based on the three main demographic concepts: City proper A city proper is the locality with legally fixed boundaries and an administratively recognized urban status that is usually characterized by some form of local government. Urban area An urban area is characterized by higher population density and vast human features in comparison to areas surrounding it. Urban areas may be cities, towns or conurbations, but the term is not commonly extended to rural settlements such as villages and hamlets. Urban areas are created and further developed by the process of urbanization and do not include large swaths of rural land, as do metropolitan areas. Metropolitan area Unlike an urban area, a metropolitan area includes not only the urban area, but also satellite cities plus intervening rural land that is socio-economically connected to the urban core city, typically by employment ties through commuting, with the urban core city being the primary labor market. In accordance with these definitions, the three largest population centers in the Americas are: Mexico City, anchor to the largest metropolitan area in the Americas; New York City, anchor to the largest urban area in the Americas; and São Paulo, the largest city proper in the Americas. All three cities maintain Alpha classification and large sc
