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.

The Reconstruction era was a period in United States history following the American Civil War, dominated by the legal, social, and political challenges of abolishing slavery and reintegrating the former Confederate States of America into the United States. During this period, three amendments were added to the United States Constitution to grant equal civil rights to the newly freed slaves. Despite this, former Confederate states often used poll taxes, literacy tests, and intimidation to control people of color.
