what we're the clan customs that fell apart

During Okonkwo's exile, the white man comes to both Umuofia and Mbanto. The missionaries arrive first, preaching a religion that seems mad to the Igbo people. They win converts, but generally the converts are men of low rank or outcasts. However, with time, the new religion gains momentum. Nwoye becomes a convert. When Okonkwo learns of Nwoye's conversion, he beats the boy. Nwoye leaves home.

Okonkwo returns to Umuofia to find the clan sadly changed. The church has won some converts, some of whom are fanatical and disrespectful of clan custom. Worse, the white man's government has come to Umuofia. The clan is no longer free to judge its own; a District Commissioner judges cases in ignorance. He is backed by armed power.

During a religious gathering, a convert unmasks one of the clan spirits. The offense is grave, and in response the clan decides that the church will no longer be allowed in Umuofia. They tear the building down. Soon afterward, the District Commissioner asks the leaders of the clan, Okonkwo among them, to come see him for a peaceful meeting. The leaders arrive, and are quickly seized. In prison, they are humiliated and beaten, and they are held until the clan pays a heavy fine.

After a release of the men, the clan calls a meeting to decide whether they will fight or try to live peacefully with the whites. Okonkwo wants war. During the meeting, court messengers come to order the men to break up their gathering. The clan meetings are the heart of Umuofia's government; all decisions are reached democratically, and an interference with this institution means the end of the last vestiges of Umuofia's independence. Enraged, Okonkwo kills the court messenger. The other court messengers escape, and because the other people of his clan did not seize them, Okonkwo knows that his people will not choose war. His act of resistance will not be followed by others. Embittered and grieving for the destruction of his people's independence, and fearing the humiliation of dying under white law, Okonkwo returns home and hangs himself.
