When France laid claim to the territories that became French Indochina, its beleaguered trading posts on the east coast of India gained a new purpose, sending Indians to help secure and administer its newest possessions and to assist in their commercial expansion. The migrants were among those peoples of France's overseas empire who gained the rights of French citizens following the French Revolution. This volume explores the consequences of their arrival in Indochina just as France was testing a new approach to its colonised peoples, an approach less enamoured with the idea of colonial citizenship and more racially ordered. This book offers an analysis of the fate of Republican ideals as they travelled between different parts of the French Empire and raised contentious issues of citizenship which engaged Indians, French authorities, and Vietnamese reformers in debate. It considers too the distinctive French colonial social order that was shaped in the process. A lively story, it is at the same time an important addition to scholarship on the French empire, on colonial society in Vietnam specifically, and on migration to Southeast Asia.
