Nigerian author Chinua Achebe
Achebe was critical of the portrayal of African people and civilization in Western literature as barbaric or inarticulate, and worked to change this false perception through his own works and through the founding of Okike, a Nigerian literary magazine. He was active in Nigerian politics and government, sometimes at the risk of his own safety. He was awarded The Man Booker International Prize in 2007.
