What is the main theme in Things Fall Apart and the conclusion?
The main themes of the novel all center around the choices and the consequences of the choices Okonkwo is forced to make during the novel. Since he is almost incapable of change, the White man's invasion of his territory is very destructive to Okonkwo. He cannot adapt to changes in customs or traditions or deal with the culture clash that occurs, especially towards the end of the novel. Thus, "things fall apart" for the main character as he fails to deal with the transformation of his society.
