The civil rights movement was a social movement and campaign from 1954 to 1968 in the United States to abolish legalized racial segregation, discrimination, and disenfranchisement in the country. The movement had its origins in the Reconstruction era during the late 19th century and had its modern roots in the 1940s, although the movement made its largest legislative gains in the 1960s after years of direct actions and grassroots protests. The social movement's major nonviolent resistance and civil disobedience campaigns eventually secured new protections in federal law for the civil rights of all Americans.

Facilities and services such as housing, healthcare, education, employment, and transportation have been systematically separated in the United States based on racial categorizations. Segregation was the legally or socially enforced separation of African Americans from whites, as well as the separation of other ethnic minorities from majority and mainstream communities. While mainly referring to the physical separation and provision of separate facilities, it can also refer to other manifestations such as prohibitions against interracial marriage, and the separation of roles within an institution. The U.S. Armed Forces were formally segregated until 1948, as black units were separated from white units but were still typically led by white officers.
