Postcolonial Theory examines the cultural, political, and economic impacts of colonialism on formerly colonized nations. It explores issues of identity, representation, and power relations, focusing on the experiences of colonized peoples and the ongoing effects of colonial legacies. Key concepts include hybridity, diaspora, and orientalism. The theory emerged in the mid-20th century, influenced by anti-colonial movements and decolonization. Major thinkers like Edward Said, Frantz Fanon, and Gayatri Spivak have shaped the field through influential texts and ideas.
