While the current discussion of ethnic, trade, and commercial diasporas, global networks, and transnational communities constantly makes reference to the importance of families and kinship groups for understanding the dynamics of dispersion, few studies examine the nature of these families in any detail. This book, centered largely on the European experience of families scattered geographically, challenges the dominant narratives of modernization by offering a long-term perspective from the Middle Ages to the twenty-first century. Paradoxically, transnational families are to be found long before the nation-state was in place.
