Hopi Tribe

The Hopi occupancy of Arizona is one of the longest occupation of land of any Native tribe in the U.S. dating back as far as 500 B.C. The Hopi located most of their villages on mesas for defensive purposes with the area surrounding land for religious purposes. With the majority of their land taken by the U.S. federal government through various ways, to this day they only retain 9% of their original land (1.6 million acres) before the large amounts of immigration from the east cost.

The website the modern Hopi tribe have appears to push the idea they were divinely chosen to rule those lands and have to soul right to cultivate them. " Since time immemorial the Hopi people have lived in Hopituskwa and have maintained our sacred covenant with Maasaw, the ancient caretaker of the earth, to live as peaceful and humble farmers respectful of the land and its resources."

There is vast information on the tribal government and its history dating back to 1936 with the names of all their representatives in case you would need to get in contact with any of them.

It even has a page for the "Hopi Code" this is the judicial section of the site showing you approved Hopi code of laws and Hopi civil procedure rules. 

Other than that the rest of the sight just seems to keep you up to date with the tribal news and the different departments of the tribe.  http://www.hopi-nsn.gov/
