Diaspora Theory has affected the literature of every language of the globe with its multiple characteristics. This literature is commonly referred to as Diasporic or Expatriate Literature. Diasporic Literature is a very broad idea and a paragliding term that involves all those literary works published by writers outside their home nation, but these works are linked to indigenous culture and background. All those authors can be considered as diasporic authors in this broad context, who write outside their nation but through their work stayed linked to their homeland. Diasporic literature has its origins in the sense of loss and alienation resulting from migration and expatriation. Diasporic literature generally deals with alienation, displacement, existential rootlessness, nostalgia, identity quest. Migrants suffer from the pain of being away from their homes, their motherland memories, the anguish of leaving behind everything familiar agonizes migrants ' minds. The diasporic Indians, too, are not breaking their ancestral land connection. There is a search for continuity and an astral impulse, an attempt to search for their origins. Settlement in alien territory leads to dislocation for them. Dislocation can be seen as a rupture with the ancient identity. By debating characteristics of expatriate or diasporic literature, the article tried to examine the reflection of Diaspora Theory and its multiple aspects in literature. The Indian contribution to diasporic literature was also evaluated in English.
