Ethnohistory is the study of cultures and indigenous peoples' customs by examining historical records as well as other sources of information on their lives and history. It is also the study of the history of various ethnic groups that may or may not still exist.
Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts. Practitioners recognize the use of such source material as maps, music, paintings, photography, folklore, oral tradition, site exploration, archaeological materials, museum collections, enduring customs, language, and placenames.
Ethnohistory is a peer-reviewed academic journal established in 1954 and published quarterly by Duke University Press on behalf of the American Society for Ethnohistory. It publishes articles and reviews in the fields of ethnohistory, historical anthropology and social and cultural history. Like its sponsoring professional society, Ethnohistory has represented a meeting ground between scholars in the disciplines of history and anthropology. Geography and other disciplines have been increasingly represented in its pages over time. Founded by scholars focused primarily on studies of Native North America, the journal has, over its history, progressively become more global in scope.
