What are the changes that confronted okonkwo upon his return tonumofia?

The church has won a powerful foothold in Umuofia. Even several men of title have joined the new religion. The white man has also built a court house, where a district commissioner imposes white law. The DC is served by a gang of kotma, African court messengers who come from far away. They are greatly hated because they are arrogant and brutal. There is a prison as well, and even men of title are being put there. The white man says that Igbo laws are foolish, and they impose their own law on the Igbo. Okonkwo is horrified.
