Postcolonialism or postcolonial studies is an academic discipline that analyzes, explains, and responds to the cultural legacy of colonialism and imperialism. Postcolonialism speaks about the human consequences of external control and economic exploitation of a native people and its lands. Drawing from postmodern schools of thought, postcolonial studies analyse the politics of knowledge (creation, control, and distribution) by examining the functional relations of social and political power that sustain colonialism and neocolonialism—the imperial regime's depictions (social, political, cultural) of the colonizer and of the colonized.
