The Pan-African Flag, also called the Marcus Garvey (UNIA Leader), UNIA (United Negro Improvement Association), Afro-American or Black Liberation Flag, was designed to represent people of the African Diaspora, black freedom, the manifestations of black aspirations, and black resistance to oppression.
The Pan-African Flag's horizontal colors each have symbolic meaning.
Red stands for blood - both shed by Africans who died in their fight for liberation, and the shared blood of the African people.
Black represents Black people.
Green is a symbol of growth and the natural fertility of Africa.
