Using case studies from Fiji, Mauritius, Trinidad and South Africa, this book explores the diaspora identities and impact of social movements on politics and nationalism among indentured Indian diaspora. It analyses the way in which diasporas are defined by themselves and others, and the types of social movements they participate in, showing how these are critical indicators of the threat they are perceived to pose. Providing an in-depth analysis of Indian Diasporas, the book will be of interest to those studying South Asian Studies, Migration and Diaspora Studies.
