From 1778 to 1871, the United States’ relations with individual American Indian nations indigenous to what is now the U.S. were defined and conducted largely through the treaty-making process. These “contracts among nations” recognized and established unique sets of rights, benefits, and conditions for the treaty-making tribes who agreed to cede of millions of acres of their homelands to the United States and accept its protection. Like other treaty obligations of the United States, Indian treaties are considered to be “the supreme law of the land,” and they are the foundation upon which federal Indian law and the federal Indian trust relationship is based.
