The United States of Africa is a hypothetical union between most or all African communities, with some interpretations including the diaspora in the Americas. The term was coined by Marcus Garvey and the Universal Negro Improvement Association through the 1924 poem "Hail, the United States of Africa." Many supporters of a United States of Africa, such as Kwame Nkrumah and Sekou Toure, saw the frameworks of the United States and Soviet Union as suitable options for a hypothetical continental union in Africa.
