Diasporic literature represents a dynamic and multifaceted genre that explores the intricate interplay between cultural factors and the application of postcolonial theories. This study seeks to provide an overview of how diasporic literature engages with these two vital aspects. Cultural factors in diasporic literature are portrayed through the lens of identity and hybridity, where displaced individuals and communities navigate their cultural identities in a new, often hybrid, environment. Furthermore, diasporic literature serves as a vital platform for the application of postcolonial theories. Key cultural factors in diasporic literature include identity and belonging, language and communication, cultural hybridity, generational conflicts, and the profound emotions associated with nostalgia and displacement. Characters within these narratives often grapple with questions of who they are in relation to their homeland's cultural heritage and the cultural influences of their host country. Language serves as both a means of communication and a symbol of cultural preservation, showcasing linguistic diversity within diaspora communities. Cultural hybridity challenges traditional notions of fixed identities, emphasizing the dynamic nature of cultural evolution. The application of postcolonial theories to diasporic literature adds depth understanding of the genre. It sheds light on how colonial legacies continue to influence diaspora communities, shaping power dynamics and cultural hierarchies. The concept of "othering" and the deconstruction of stereotypes inherent in these narratives are examined through the lens of postcolonial thought. Cultural hybridity, often celebrated in diasporic literature, is reframed as an act of resistance against cultural erasure. Additionally, the impact of globalization and neocolonialism on diaspora communities is scrutinized. By scrutinizing diasporic literature for cultural factors and applying postcolonial theories, this study not only enriches our comprehension of the diaspora experience but also provides a critical framework for analysing the enduring legacies of colonialism in contemporary societies. It underscores the power of literature
