How does the theme of politics and religion contribute to our understanding of the disintegration of the African society?

Tribal belief

Particularly since one of the threats to Igbo life is the coming of the new religion, tribal belief is a theme of some importance. Igbo religious beliefs explain and provide meaning to the world; the religion is also inextricable from social and political institutions. Achebe also shows that Igbo religious authorities, such as the Oracle, seem to possess uncanny insights. He approaches the matter of Igbo religion with a sense of wonder.

Social disintegration

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.
