Ethnohistory
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. The term is most commonly used in writing about the history of the Americas. Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts.
