Portrait of Samuel Freeman Miller Samuel Freeman Miller United States v. Kagama — Opinion of the Court

But they asserted an ultimate title in the land itself, by which the Indian tribes were forbidden to sell or transfer it to other nations or peoples without the consent of this paramount authority. When a tribe wished to dispose of its land, or any part of it, or the state or the United States wished to purchase it, a treaty with the tribe was the only mode in which this could be done. The United States recognized no right in private persons, or in other nations, to make such a purchase by treaty or otherwise. With the Indians themselves these relations are equally difficult to define.

The Indian reservation in the case before us is land bought by the United States from Mexico by the treaty of Guadaloupe Hidalgo, and the whole of California, with the allegiance of its inhabitants, many of whom were Indians, was transferred by that treaty to the United States. The relation of the Indian tribes living within the borders of the United States, both before and since the Revolution, to the people of the United States, has always been an anomalous one, and of a complex character.
