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 connections to British officials. His sister, Molly Brant, was the wife 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 known as "Brant's Volunteers" 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. In 1784, Frederick Haldimand granted Joseph Brant and his followers a land treaty to replace what they had lost in New York State at the Sandusky Council after the Revolution. This tract, the Haldimand Grant, was about in size, 12 miles (19.2 kilometers) wide along the whole trace of the Ouse or Grand River in what is now southwestern Ontario. Chief Brant relocated with most of his people to Upper Canada to the area which is now Six Nations Reserve, where he remained a prominent leader. Early years Joseph was born in the Ohio Country in March 1743, somewhere along the Cuyahoga River during the hunting season when the Mohawk traveled to the area from Kanienkeh ("the Land of the Flint", the Mohawk name for their homeland in what is now upstate New York). He was named Thayendanegea, which in the Mohawk language means "He places two bets together", which came from the custom of tying the wagered items to each other when two parties placed a bet. As the Mohawk were a matrilineal culture, he was born into his mother's Wolf Clan. The Haudenosaunee League, of which the Mohawks were one of the Six Nations, was divided into clans headed by clan mothers. Anglican Church records at Fort Hunter, New York, noted that his parents were Christians and their names were Peter and Margaret Tehonwaghkwangearahkwa.
