The Indian Removal Act of 1830 characterized the U.S. government policy of Indian removal, which called for the forced relocation of Native American tribes living east of the Mississippi River to lands west of the river. While it did not authorize the forced removal of the indigenous tribes, it authorized the President to negotiate land exchange treaties with tribes located in lands of the United States. The Intercourse Law of 1834 prohibited United States citizens from entering tribal lands granted by such treaties without permission, though it was often ignored.
