Nonintercourse Act

Family of U.S. laws related to Native American tribal rights

The Nonintercourse Act is the collective name given to six statutes passed by the United States Congress in 1790, 1793, 1796, 1799, 1802, and 1834 to set boundaries of American Indian reservations. The various acts were also intended to regulate commerce between White Americans and citizens of Indigenous nations. The most notable provisions of the act regulate the inalienability of aboriginal title in the United States, a continuing source of litigation for almost 200 years. The prohibition on purchases of Indian lands without the approval of the federal government has its origins in the Royal Proclamation of 1763 and the Confederation Congress Proclamation of 1783.
