Postcolonialism emerged in the mid-20th century to analyze the time after colonialism. It focuses on regions like India, Africa, and Southeast Asia that were formerly colonized by European powers. Postcolonial theory examines the relationships between colonizers and colonized peoples and challenges the dominant cultural perspectives of colonial institutions. Key aspects include considering the exoticization of non-European peoples in literature and representations, acknowledging the influence of colonial languages, and exploring hybrid cultural identities formed through colonial interactions.
