Migration has always been a feature of Nepali society. Waves of Khas, Brahmans, and associated service castes were already moving south and east through the Himalayan foothills a millennium ago. As the population expanded, Nepalis from all backgrounds have continually moved onwards in search of new farmland and new opportunities, often encouraged to do so by local communities, local headmen, and the state. In the late nineteenth and twentieth centuries, that process continued eastwards from present-day Nepal into the north-east of India and beyond. Over the last thirty years international labour migration, as well as migration consequent on tertiary education, has radically changed the patterns of settlement of Nepalis outside their homeland. The present volume covers the many different contexts-from the USA to the Gulf, from India to Burma and Singapore-where large numbers of Nepalis are settled or working long-term. Taken together, and organized by region of settlement, the contributions in this book provide a comprehensive overview of Nepali diaspora populations around the world in their contemporary contexts. The common theme binding this volume is the exploration of the process of ‘ethnogenesis’ or the emergence of strong ethnic identities in which the contributors analyse how such identities strengthen more easily in the diaspora with a large population, than in the homeland.
