Both Marcus Garvey (1887-1940) and the National Association for the Advance of Colored People (NAACP) had equality between blacks and whites as their primary goal.
Their methods were different, though. Garvey believed in "equal but separated" and led a campaign for black people to return to Africa. He stood for the establishment of a black nation on the west coast of Africa for African Americans.
The NAACP on its turn was created to fight for equality and for democratic inclusion of African Americans. NAACP fights through the judicial system, peaceful protests, and lobbying. It didn't share Garvey's defense of separatism and it was an important factor in the fight against segregation.
