Historiography

According to historian David Rich Lewis, American popular histories, film, and fiction have given enormous emphasis to the Indian wars. New ethno-historical approaches became popular in the 1970s which mixed anthropology with historical research in hopes of gaining a deeper understanding of the Indian perspective. During the 1980s, human rights abuses by the US government were increasingly studied by historians exploring the impact of the wars on Indian cultures. Prior to this, popular history was heavily influenced by Dee Brown 's non-academic treatment of historical events in the 1970 non-fiction book, Bury My Heart at Wounded Knee. In more academic history, Francis Jennings 's 1975 book The Invasion of America: Indians, Colonialism, and the Cant of Conquest was notable for criticizing the Puritans and rejecting the traditional portrayal of the wars between the Indians and colonists. The revisionist historian Jeffrey Ostler has argued that some of the events within the American Indian Wars would fit into the modern legal definition of genocide.
