novelist and playwright best known for works that explore the role of the supernatural in Nigerian village life.

Amadi, an Ijo (Ijaw) who wrote in English, was educated at Government College, Umuahia, and University College, Ibadan, in physics and mathematics. He served in the Nigerian army, taught, and worked for the Ministry of Information. Sunset in Biafra (1973), his only work of nonfiction, recounts his experiences as a soldier and civilian during the Biafran conflict.

Amadi is best known, however, for his historical trilogy about traditional life in rural Nigeria: The Concubine (1966), The Great Ponds (1969), and The Slave (1978). These novels concern human destiny and the extent to which it can be changed; the relationship between people and their gods is the central issue explored. Amadi is a keen observer of details of daily life and religious rituals, which he unobtrusively describes in his dramatic stories. Similar emphases are found in his verse play, Isiburu (1973), about a champion wrestler who is ultimately defeated by the supernatural power of his enemy. Among his other works is Pepper Soup and the Road to Ibadan (1977).
