Haile Selassie I
In 1963, Haile Selassie presided over the formation of the Organization of African Unity (OAU), the precursor of the today's African Union (AU). The new organization would establish its headquarters in Addis Ababa. In May that year, Haile Selassie was elected as the OAU's first official chairperson, a rotating seat. Along with Modibo Keïta of Mali, the Ethiopian leader would later help successfully negotiate the Bamako Accords, which brought an end to the border conflict between Morocco and Algeria. In 1964, Haile Selassie would initiate the concept of the United States of Africa, a proposition later taken up by Muammar Gaddafi.
