The Negro Artist and the Racial Mountain” In (1926) was a short essay written by poet Langston Hughes for The Nation magazine. It became the manifesto of the Harlem Renaissance. In it Hughes said that black artists in America should stop copying whites, that they will never create anything great that way.
