The Niggerati was the name used, with deliberate irony, by Wallace Thurman for the group of young African American artists and intellectuals of the Harlem Renaissance. "Niggerati" is a portmanteau of " nigger" and "literati". The rooming house where he lived, and where that group often met, was similarly christened Niggerati Manor. The group included Zora Neale Hurston, Langston Hughes, and several of the people behind Thurman's journal FIRE!! (which lasted for one issue in 1926), such as Richard Bruce Nugent (the associate editor of the journal), Jonathan Davis, Gwendolyn Bennett, and Aaron Douglas.
At a time when homophobia and sexism were common, and when the African American bourgeoisie sought to distance itself from the slavery of the past and seek social equality and racial integration, the Niggerati themselves appeared to be relatively comfortable with their diversity of gender, skin colour, and background. After producing FIRE!!, which failed because of a lack of funding, Thurman persuaded the Niggerati to produce another magazine, Harlem. This, too, lasted only a single issue.
