The novel follows the life of Okonkwo, an Igbo ("Ibo" in the novel) man and local wrestling champion in the fictional Nigerian clan of Umuofia. The work is split into three parts, with the first describing his family, personal history, and the customs and society of the Igbo, and the second and third sections introducing the influence of British colonialism and Christian missionaries on Okonkwo, his family and wider Igbo community.
