I would like to look at the proto-historic period (1500-1750) of the Navajo or Dine’, an Athabaskan tribe of the Four Corners area. Specifically, the area in the San Juan River Valley known as Dinetah or the Navajo homeland. The period is characterized proliferation Navajo material culture in the Dinetah region. Prior to this period, the distinctions between Navajo and Apache tribes, both Athabaskan speaking tribes, were less distinct. How did the two tribes become distinct and how did their interactions with Puebloan people, other Native groups and newly arrived Spanish colonists shape their identity.
