How does the political environment fall apart in Things Fall Apart?

The political environment falls apart in several ways.

First the Christians take away the lowest class, or the osu, and other outcasts.
Secondly, an aggressive conflicting system is introduced, which forces people to either switch to the new system or suffer as a result. Schools, courts, and soldiers all contribute to this new system, which brings wealth and privilege to those who join it.
