Historians who have sought to examine the native societies of the Americas, whether before or after the European conquest, have often felt a need to go beyond the traditional bounds of the discipline, loose as they are, in their efforts to comprehend the values and the actions of people whose societies did not conform to the European pattern. In the study of Indian societies, anthropology and history joined early and have continued to collaborate; the very term ethnohistory, which some would consider an unnecessary coining of a new name for social history, is clear evidence of this union. Further evidence, if such be necessary, is provided by the degree to which scholars have drawn upon the approaches and conclusions of both disciplines in their work. While this practice is of long standing, earlier work showed a general tendency to utilize the data and the conclusions of other disciplines, rather than drawing upon the theories and the approaches developed by others in order to reexamine one's own materials. This highly pragmatic approach to the potential contributions of other disciplines is increasingly giving way to deeper collaboration and interchange.
