This is a book on the rise and fall of diasporic communities in Early Modern urban centers in Denmark and Sweden. It contains 17 chapters written by archaeologists, historians and scientists, ranging from in-depth studies of artefacts, biofacts and archaeological features to large-scale analyses of community formation among natives and migrants of multiple origins. The plethora of sources and approaches afforded by the numerous disciplines involved enables a significant new insight into the creation and recreation of migrant communities in these Early Modern towns.
