Sayenqueraghta (c. 1707 – 1786) was the war chief of the eastern Seneca tribe in the mid-18th century. He was born the son of Cayenquaraghta, a prominent Seneca chief of the Turtle clan in western New York. He lived most of his life at Kanadaseaga, near the present day town of Geneva, New York. He obtained his rank of war chief in 1751. Before the American Revolution he was referred to as chief of the Senecas.
He served on the British side against the French during the French and Indian War and was present at the Battle of Fort Niagara.
During Pontiac's War he was the Seneca war-chief who defeated a British force at the Battle of Devil's Hole. In 1764 the Seneca came to Fort Niagara where they made peace with the British government and Sayenqueraghta "buried the Axe" with Britain.
In 1765 he received Samuel Kirkland, Sir William Johnson's envoy, and at that time extended protection to Kirkland by adopting him into his family.[1]
Also in 1765, he along with Handsome Lake and about one hundred other Seneca warriors went on an expedition against the Cherokee and Choctaw.[2] This expedition was remembered nearly a century later for the loot of scalps and other trophies obtained.
