Black nationalism

Black nationalism is a type of racial nationalism or pan-nationalism which espouses the belief that black people are a race, and seeks to develop and maintain a black racial and national identity.[1][2] Black nationalist activism revolves around the social, political, and economic empowerment of black communities and people, especially to resist their cultural assimilation into white culture (through integration or otherwise), and maintain a distinct black identity.[1]

White nationalism

White nationalism is a type of racial nationalism or pan-nationalism which espouses the belief that white people are a race[1] and seeks to develop and maintain a white racial and national identity.[2][3][4] Many of its proponents identify with and are attached to the concept of a white nation, or a "white ethnostate".[5]
