things fall apart

I think the title explicitly states the theme of social disintegration or when "things fall apart". Towards the end of the novel, we witness the events by which Igbo society begins to fall apart. Religion is threatened, Umuofia loses its self-determination, and the very centers of tribal life are threatened. These events are all the more painful for the reader because so much time has been spent in sympathetic description of Igbo life; the reader realizes that he has been learning about a way of life that no longer exists.
