Things Fall Apart is a novel written by Nigerian author Chinua Achebe. It focuses on pre-colonial life in the south-eastern part of Nigeria and the arrival of the Europeans during the late nineteenth century.
The novel addresses 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 divided 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 the Igbo community.
