Between the Revolutionary War and the aftermath of the Civil War, over the course of almost a century, the United States and Native American nations signed some 368 treaties that would define their relationship for centuries to come.
The treaties keyed off the fundamental idea that each tribal group was an independent nation, with their own right to self-determination and self-rule. But as white settlers began moving onto Native American lands, this idea came into conflict with the relentless pace of westward expansion—resulting in many broken promises on the part of the U.S. government.
