Postcolonialism refers to intellectual works and theories that emerged in the mid-20th century in response to colonialism. It focuses on regions that were formerly colonized, including parts of Africa, Asia, and India. Postcolonial theory examines the cultural legacy of colonialism and the conflicts between colonizers and indigenous populations. Important theorists include Edward Said, Homi Bhabha, and Gayatri Spivak. Postcolonial criticism seeks to challenge Eurocentric perspectives and address how colonial powers represented foreign cultures.
