How does Chinua Achebe portray colonialism using Things Fall Apart?essay question

The picture that Achebe paints is not a very positive one,
using the story to depict a colonial power that enters and then brings about the death
of the Igbo culture.  Through the Christian religion as well as technological advances,
the agents of colonial power enter the village and work tirelessly to convince the Igbo
that their ways are the ways of the past and of ignorance and that the ways of the white
man are better.  They create rifts in the village and seek to exacerbate those by
continuing to point out ways that the village is
backwards.

Eventually the interference of the white men and
the conflict of their ways with the traditions of the Igbo bring about the death of the
Igbo culture signified in part by Okonkwo's suicide.
