African literature has a strong oral tradition and incorporates important truths and teachings. It uses artistic language to build communities rather than just for beauty. Major themes include pre-colonial oral myths, slave narratives from the colonial period, and post-independence works addressing themes of liberation, tradition vs modernity, and social issues. Famous African authors represented include Chinua Achebe, Wole Soyinka, Olaudah Equiano, and his memoir describing the harrowing conditions aboard a slave ship.
