U.S.–Native American treaties

From 1778 to 1871, the United States government entered into more than 500 treaties with the Native American tribes; all of these treaties have since been violated in some way or outright broken by the U.S. government, with Native Americans and First Nations peoples still fighting for their treaty rights in federal courts and at the United Nations.

In addition to treaties, which are ratified by the U.S. Senate and signed by the U.S. President, there were also Acts of Congress and Executive Orders which dealt with land agreements. The U.S. military and representatives of a tribe, or sub unit of a tribe, signed documents which were understood at the time to be treaties, rather than armistices, ceasefires and truces.

The entries from 1784 to 1895 were initially created by information gathered by Charles C. Royce and published in the U.S. Serial Set, Number 4015, 56th Congress, 1st Session, in 1899. The purpose of the Schedule of Indian Land Cessions was to indicate the location of each cession by or reservation for the Indian Tribes. Royce's column headings are titled: "Date, Where or how concluded, Reference, Tribe, Description of cession or reservation, historical data and remarks, Designation of cession on map, Number, Location".

The Ratified Indian Treaties that were transferred from the U.S. State Department to the National Archives were recently conserved and imaged for the first time, and in 2020 made available online with additional context at the Indigenous Digital Archive's Treaties Explorer, or DigiTreaties.org.

1778–1799

1830–1839

1840–1849

1850–1859

1860–1869

1870–1879

Treaty-making between various Native American governments and the United States officially concluded on March 3, 1871 with the passing of the United States Code Title 25, Chapter 3, Subchapter 1, Section 71 (25 U.S.C. § 71). Pre-existing treaties were grandfathered, and further agreements were made under domestic law.

1880–present
