In 1966, in Dakar, Senegal, over two thousand dancers, artists, and writers from Africa and the African Diaspora came together to participate in the historic First World Festival of Negro Arts. William Greaves traveled to Dakar with the United States Information Agency to document the historic event, which was attended by an extraordinary cast of luminaries, both on stage and in the audience, from thirty countries—among them, Duke Ellington, Langston Hughes, Alvin Ailey, Aimé Césaire, and President Leopold Senghor.
