African Americans, one of the largest of the many ethnic groups in the United States. African Americans are mainly of African ancestry, but many have non-Black ancestors as well.
African Americans are largely the descendants of enslaved people who were brought from their African homelands by force to work in the New World. Their rights were severely limited, and they were long denied a rightful share in the economic, social, and political progress of the United States. Nevertheless, African Americans have made basic and lasting contributions to American history and culture.
At the turn of the 21st century, more than half the country’s more than 36 million African Americans lived in the South; 10 Southern states had Black populations exceeding 1 million. African Americans were also concentrated in the largest cities, with more than 2 million living in New York City and more than 1 million in Chicago. Detroit, Philadelphia, and Houston each had a Black population between 500,000 and 1 million.
As Americans of African descent reached each new plateau in their struggle for equality, they reevaluated their identity. The slaveholder labels of black and negro (Spanish for black) were offensive, so they chose the euphemism coloured when they were freed. Capitalized, Negro became acceptable during the migration to the North for factory jobs. Afro-American was adopted by civil rights activists to underline pride in their ancestral homeland, but Black—the symbol of power and revolution—proved more popular. All these terms are still reflected in the names of dozens of organizations. To reestablish “cultural integrity” in the late 1980s, Jesse Jackson proposed African American, which—unlike some “baseless” colour label—proclaims kinship with a historical land base. In the 21st century the terms Black and African American both were widely used.
