National Association for the Advancement of Colored People (NAACP), organization composed mainly of American blacks, but with many white members, whose goal is the end of racial discrimination and segregation.

The association was formed as the direct result of the lynching (1908) of two blacks in Springfield, Ill. The incident produced a wide response by white Northerners to a call by Mary W. Ovington, a white woman, for a conference to discuss ways of achieving political and social equality for blacks. This conference led to the formation (1910) of the NAACP, headed by eight prominent Americans, seven white and one, William E. B. Du Bois , black. The selection of Du Bois was significant, for he was a black who had rejected the policy of gradualism advocated by Booker T. Washington and demanded immediate equality for blacks. From 1910 to 1934 Du Bois was the editor of the associations periodical The Crisis, which reported on race relations around the world. The new organization grew so rapidly that by 1915 it was able to organize a partially successful boycott of the motion picture The Birth of a Nation, which portrayed blacks of the Reconstruction era in a distorted light.

Most of the NAACPs early efforts were directed against lynching . In this area it could claim considerable success. In 1911 there were 71 lynchings in the United States, with a black person the victim 63 times by the 1950s lynching had virtually disappeared. Since its beginning, and with increasing emphasis since World War II, the NAACP has advocated nonviolent protests against discrimination and has disapproved of extremist black groups such as SNCC and the Black Panthers in the 1960s and 70s and CORE and the Nation of Islam in the 1980s and 90s, many of which criticized the organization as passive. While complacent in the 1980s, it became more active in legislative redistricting, voter registration, and lobbying in the 1990s.

Well-known leaders of the NAACP include Moorfield Storey (1910–29), Walter White (1931–55),
