(1905–10), organization of black intellectuals led by W.E.B. Du Bois (Du Bois, W.E.B.) and calling for full political, civil, and social rights for black Americans. This stance stood in notable contrast to the accommodation philosophy proposed by Booker T. Washington in the Atlanta Compromise of 1895. The Niagara Movement was the forerunner of the National Association for the Advancement of Colored People (NAACP) (National Association for the Advancement of Colored People). In the summer of 1905, 29 prominent blacks, including Du Bois, met secretly at Niagara Falls, Ont., and drew up a manifesto calling for full civil liberties, abolition of racial discrimination, and recognition of human brotherhood. Subsequent annual meetings were held in such symbolic locations as Harpers Ferry, W.Va., and Boston's Faneuil Hall.

Despite the establishment of 30 branches and the achievement of a few scattered civil-rights victories at the local level, the group suffered from organizational weakness and lack of funds as well as a permanent headquarters or staff, and it never was able to attract mass support. After the Springfield (Ill.) Race Riot (Springfield Race Riot) of 1908, however, white liberals joined with the nucleus of Niagara “militants” and founded the NAACP the following year. The Niagara Movement disbanded in 1910, with the leadership of Du Bois forming the main continuity between the two organizations.
