Take a postcolonial critical approach to Chinua Achebe's Things Fall Apart.
For us, “[postcolonialism] is the critical academic study of the cultural legacy of colonialism and imperialism, focusing on the human consequences of the control and exploitation of colonized people and their lands” (Wikipedia). In the study of literature, a postcolonial lens can look like a lot of different things, but it will always either be 1) concerned with the way a work of literature describes peoples who were once colonized, or who are still under colonial occupation, and/or descendants of once-colonized people, and/or those who left their ancestral homelands in a diaspora partly or entirely motivated by imperial aggression; or, 2) concerned with the way a text was produced with regard to colonial power dynamics and the identities and broader cultural expressions of those who were colonized at some point or points prior to the work's composition.
Simply choose one of the Unit 3 novels and describe and discuss, in an analytical way, how colonizers and the colonized are represented (or not represented) in the action of the novel, what meanings you glean from these representations (or lack thereof), and what the significance of these findings might be in the greater scheme of human history or our future as a species.
