Related documents: [0]  [DOC] Pan-Africanism is a worldwide intellectual movement that aims to encourage and strengthen bonds of solidarity between all people of African descent. Based upon a common fate going back to the Atlantic slave trade, the movement extends beyond continental Africans, with a substantial support base among the African diaspora in the Caribbean, Latin America and the United States. It is based on the belief that unity is vital to economic, social, and political progress and aims to "unify and uplift" people of African descent. The ideology asserts that the fate of all African peoples and countries are intertwined. At its core Pan-Africanism is "a belief that African peoples, both on the continent and in the diaspora, share not merely a common history, but a common destiny". [END]
