The Pan-African flag—also known as the Afro-American flag, Black Liberation flag, UNIA flag and various other names—is a tri-color flag consisting of three equal horizontal bands of (from top down) red, black and green.[1] The Universal Negro Improvement Association and African Communities League (UNIA-ACL) formally adopted it on August 13, 1920, in Article 39 of the Declaration of the Rights of the Negro Peoples of the World, during its month-long convention at Madison Square Garden in New York City.[2][3] Variations of the flag can and have been used in various countries and territories in the Americas to represent Garveyist ideologies
