Book excerpt: The essays in this volume have been written by leading experts in their respective fields and bring together established scholars with a new generation of migration and transnational historians. Their work weaves together the ‘new’ imperial and the ‘new’ migration histories, and is essential reading for scholars and students interested in the interplay of migration within and between the local, regional, imperial, and transnational arenas. Furthermore, these essays set an important analytical benchmark for more integrated and comparative analyses of the range of migratory processes – free and coerced – which together impacted on the dynamics of power, forms of cultural circulation and making of ethnicities across a British imperial world.
