Postcolonial literature emerged after European colonialism, reflecting experiences of people from former colonies. It addresses colonization's effects on indigenous populations, exploring decolonization, national identities, and power dynamics between colonizers and colonized. Key themes include identity, resistance, language, diaspora, and trauma. Authors like Chinua Achebe, Salman Rushdie, and Chimamanda Ngozi Adichie use techniques such as magical realism and non-linear narratives to challenge Eurocentric perspectives and assert cultural identities.
