Tribe: A Governmental phrase; an Anglo-American concept with Germanic roots applied to the Indigenous peoples of North America during the Reorganization Act of 1934.

Creating a "Tribe": After the Dine peoples returned to their homelands, in the late 1800s, from Bosque Redondo, where they had been held as prisoners of war following the historic Long Walk, the discovery of minerals and natural recourses was made on their land. Because of the nature of federal trusteeship, it became necessary for the Federal Government to create a "tribal" government, with "chiefs" i.e. leaders or chairmen among the Navajo. This chiefdom system of government (totally foreign to the Navajo, who are traditionally democratic) had to be created so that corporate interests could acquire official land leases from the "tribe" in order to exploit their lands.

In other-words, because reservation land is held in trust to Native communities, only those communities have the authority to let outsiders dig for Uranium and other resources on their lands. Because the majority of Native peoples during the 1930s wanted no part of such desecration, the only way the slime balls could get such blasphemous land leases out of them was to force them into creating Anglo-American-style governments. You get the idea.
