Postcolonial literature is literature that is written by people who have been through colonialism - a situation where powerful countries take over and control an area or people for a period of time. Postcolonial literature usually explores the feelings of people in the area or people taken over by colonialism, often focusing on the struggles of being from an oppressed background, and the effects of colonialism on both the people and the area. It is written to tell their stories, and to challenge the power of the colonial forces.
