This research paper investigates the persistent complexities of postcolonial alienation and cultural identity through a qualitative, text-based comparative literary lens. Focusing on acclaimed novels by prominent authors such as Chinua Achebe, Salman Rushdie, Ngũgĩ wa Thiong’o, and Chimamanda Ngozi Adichie, the study explores how characters navigate the dual pressures of detachment from ancestral heritage and marginalization within modern socio-political structures. By integrating foundational theories from Frantz Fanon, Edward Said, and Homi K. Bhabha, the analysis demonstrates how narrative techniques mirror the fragmented psychological states of displaced protagonists. The findings reveal that postimperial alienation operates simultaneously as an internal loss of native roots and an external exclusion within neo-colonial landscapes. The comparative approach highlights distinct regional nuances alongside shared global struggles against historical imperialism. Ultimately, this inquiry emphasizes the vital role of postcolonial literature in articulating modern displacement, offering profound insights into ongoing processes of resilience, hybridity, and psychological recovery within an increasingly interconnected yet fractured world.
