Abdulrahman Mohamed Babu was a writer, revolutionary and politician. He led the 1964 Zanzibar revolution and was a cabinet minister in Tanzania until 1972 when he was imprisoned by Nyerere. He was eventually released six years later with the aid of an international campaign. Babu taught at San Francisco State University and Amherst College and later moved to London at Birkbeck College. He became a friend and source of strength to struggling peoples all over the world, and he continued to play a unique role in African politics. In the face of the intensifying economic stranglehold and ideological dominance of Western agencies, he spoke and wrote of the need for a “second liberation” of Africa. A committed Marxist, he was a passionate believer in a socialist Pan-Africanism.
