Federally recognized American Indian Tribes are distinct in that they have a unique trust-responsibility relationship with the federal government as well as legal sovereign recognition with state, and local governments. This relationship was developed through treaties, land cedings, and executive orders. There are 566 federally recognized tribes in the United States and 22 of those tribes are in the state of Arizona. Approximately one-third of the state of Arizona is comprised of tribal lands, therefore it is important for large universities like Arizona State University to work together to develop strong efficient working relationships. Existing relationships between ASU and certain tribal communities have a demonstrated benefit for both sides which includes sharing of knowledge, development of tribally controlled universities, research opportunities and educational opportunities for tribal members.
