This Perspective presents an overview of the archaeology of pluralistic colonies (approximately late 1500s-1800s) in North America. It complements the other special feature papers in this issue on ancient societies in Mesoamerica, the Near East, the Armenian Highlands, Peru, and China by presenting another body of literature for examining the dynamics of change in multiethnic societies from a different time and place. In synthesizing archaeological investigations of mercantile, plantation, and missionary colonies, this Perspective shows how this research is relevant to the study of pluralism in both historic and ancient societies in three ways. (i) It enhances our understanding of interethnic relationships that took place in complex societies with imposing political hierarchies and labor structures. (ii) It helps us to refine the methods used by archaeologists to define and analyze multiethnic communities that were spatially delimited by ethnic neighborhoods. Finally, (iii) it presents more than a half century of experimentation with various models (e.g., acculturation, creolization, ethnogenesis, and hybridity) that have been used to study the dynamics of culture change in multiethnic societies.European colonies | indigenous peoples | enslaved laborers | colonial hierarchies | ethnic neighborhoodsAn important issue in the study of the dynamics of change in multiethnic societies is understanding how pluralism may have created new forms of social relationships, cultural practices, and sociopolitical organizations over time. Archaeologists have long been interested in documenting ancient places where large, pluralistic populations resided. There is growing interest in the investigation of culture contact, pluralism, and social dynamics in ancient cultures using crosscultural, comparative analyses (1-3). The comparative study of social formations in complex societies is particularly timely for the field of archaeology (4, 5). That is why the papers in this PNAS Special Feature are so important: they make a significant contribution in broadening our perspective and understanding about the social dynamics of complex, multiethnic polities in Mesoamerica, the Near East, the Armenian Highlands, Peru, and China.The purpose of this Perspective is to place the PNAS papers into the broader archaeological literature on pluralistic places. It is important to recognize that an extensive body of research exists for the study of multiethnic communities. Since the 1960s historical archaeologists have used a diverse range of datasets, including archaeological materials, archival documents, ethnographic accounts, and oral traditions to examine interethnic interactions in colonial settings. I begin by presenting a brief overview on the archaeology of colonialism in North America that has focused on settler, managerial, and missionary colonies. I then outline how this research may be relevant for scholars working elsewhere in the world who are examining the dynamics of change in multiethnic societies characterized by notable politica...
