This paper explores the profound impact of postcolonial theory on contemporary English literature. It examines how postcolonial theory has reshaped literary narratives, themes, and character development in works produced in the aftermath of colonialism. By analyzing key texts and authors, the paper demonstrates how postcolonial discourse has influenced the representation of identity, power dynamics, and cultural hybridity. The study further delves into how contemporary English literature reflects ongoing struggles with colonial legacies and the quest for decolonization in a globalized world.
