Léopold Sédar Senghor
Modibo Keïta devoted his entire life to African unity. He first played a part in the creation of the Federation of Mali with Léopold Sédar Senghor. After its collapse, he moved away from Léopold Sédar Senghor, but with Sékou Touré, the president of Guinea, and Kwame Nkrumah, the President of Ghana, he formed the Union of the States of Western Africa. In 1963, he played an important role in drafting the charter of the Organization of African Unity (OAU).
