Southwestern Tribes.

At the time of first contact, trade among the Indians of the Southwest was similar to that practiced in the rest of North America. Like their eastern counterparts, both the sedentary Pueblo Indians and nearby semisedentary tribes such as the Navajo reciprocally exchanged gifts to cement personal and political relationships. In several important ways, though, trade in the Southwest differed from commercial interactions in the eastern part of North America. First, early southwestern Indians exchanged goods with Mesoamerican civilizations in the pansouthwest commercial network to a far greater degree than they traded with other North American Indians. More important, sedentary pueblo-dwelling Indians such as the Tiwas and semisedentary plains tribes such as the Apaches developed acomplementary trading relationship in the centuries prior to the European invasion that was far more complex than the eastern Indians' reciprocity-based commerce.
