Thayendanegea or Joseph Brant (March 1743 – November 24, 1807) was a Mohawk military and political leader, based in present-day New York, who was closely associated with Great Britain during and after the American Revolution. Perhaps the Native American of his generation best known to the Americans and British, he met many of the most significant Anglo-American people of the age, including both George Washington and King George III.
While not born into a hereditary leadership role within the Iroquois League, Brant rose to prominence due to his education, abilities and his connections to British officials. His sister, Molly Brant, was the consort of Sir William Johnson, the influential British Superintendent of Indian Affairs in the province of New York. During the American Revolutionary War, Brant led Mohawk and colonial Loyalists against the rebels in a bitter partisan war on the New York frontier. He was accused by the Americans of committing atrocities and given the name "Monster Brant", but the accusations were argued by later historians to have been false. After the war, he relocated with most of his people to Canada to the Six Nations Reserve, where he remained a prominent leader
