List of United States treaties

This is a list of treaties to which the United States has been a party or which have had direct relevance to U.S. history.
Pre-Revolutionary War treaties.
Before the United States Declaration of Independence in 1776, the sovereign of the United Kingdom and the leaders of various North American colonies negotiated treaties that affected the territory of what would later become the United States.
U.S. international treaties.
These are treaties that the United States has made with other sovereign international states. This is mostly to distinguish them from the next category. Under the treaty clause of the United States Constitution, treaties come into effect upon final ratification by the President of the United States, provided that a two-thirds majority of the United States Senate concurs.
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 US government, Native Americans and First Nations peoples are still fighting for their treaty rights in federal courts and at the United Nations.
In addition to treaties, which are ratified by the US Senate and signed by the US 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.
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 (). Pre-existing treaties were grandfathered, and further agreements were made under domestic law.
