Black supremacy or black supremacism is an ideology which is centered upon the belief or promotes the belief that black people are superior to people of other racial backgrounds and therefore, black people should politically, economically, and socially dominate non-black people. Like other racial supremacist ideologies and related social movements, it is based on a notion of biological race. In that sense, all forms of racial supremacy are essentialist ideologies that conflict with constructionist views of race. Despite these commonalities, according to most scholars of race, variants of racial supremacy differ significantly because, historically, they have wielded structural power and shaped popular and political discourses to different degrees. For example, some forms of racial supremacy have remained ideologies shared by a small faction and others have been structurally implemented on a broad social scale (see social structure and racism) by a majority.
