Building on the civil rights initiatives begun during World War II, African Americans posed the most dramatic challenge to the status quo of the 1950s as they sought to overcome discrimination and segregation. Every southern state mandated rigid segregation in public settings ranging from schools to cemeteries. Voting laws and practices in the South disfranchised the vast majority of African Americans. Employment discrimination kept blacks at the bottom throughout the country. Schools, restaurants, and other public spaces were often as segregated, though usually not by law, in the North as in the South.

Although black protest was as old as American racism, in the 1950s grassroots movements arose that attracted national attention and the support of white liberals. Pressed by civil rights groups, the Supreme Court delivered significant institutional reforms, but the most important changes occurred among blacks themselves. Ordinary African Americans in substantial numbers sought their own liberation, building a movement that would transform race relations in the United States.
