The Tribes once freely occupied the land in the tri-state area of what is now Idaho, Nevada, and Oregon. This changed with the coming of migrants from the eastern United States and Europe, especially after the mid-19th century. Land and resources were wrestled away from the Shoshone and Paiute. The tribes made treaties with the United States, of which some were ratified by the Senate and others not. The chiefs signed all the treaties in good faith and for the survival of their peoples.
