This paper explores the critical dimensions of post-colonial theory and its profound implications for global politics. Emerging in the mid-20th century, post-colonial theory seeks to analyze and understand the enduring impacts of colonialism on societies, cultures, and international relations. The framework interrogates historical narratives, revealing how colonial legacies have shaped contemporary power dynamics, identities, and economic structures. Key concepts such as hybridity, the subaltern, and Orientalism challenge traditional binary distinctions between the colonizer and the colonized, urging a more nuanced understanding of cultural interactions and identities. These insights are crucial for rethinking international relations, where the voices of formerly colonized nations are often marginalized in favor of Western-centric narratives.
