The Yearbook of Transnational History is dedicated to disseminating pioneering research in the field of transnational history. This fifth volume advances the frontier of transnational history into early modern times. The six chapters of this volume explore topics and themes from early modern times to the fall of Communism. This volume includes chapters about the Huguenots and Sephardi Jews as transnational nations in the seventeenth and eighteenth century, the construction of cannabis knowledge cultures in the transatlantic world of the nineteenth century, the role of the German pastor Martin Niemoeller in the construction of transnational religious identities in the aftermath of World War II, and the labor migration - from Cuba to East Germany - within the Socialist world in the 1970s and 1980s.
