Booker T. Washington (1856-1915) advocated gradualism. That meant being patient and doing what white society would allow, which meant changes and better times for blacks would come slowly.
A different point of view was taken by W.E.B. Du Bois (1868-1963). Du Bois noted that Washington's approach was not accomplishing any real gains for blacks. He also felt that Washington's point of view showed acceptance of the racial inferiority of blacks. Plus he saw that institutions in the black community were being dominated by persons like Washington, rather than really empowering all individuals for themselves.

Du Bois was strongly active in the National Association for the Advancement of Colored People (NAACP).
