John Abeel III, known as Gaiänt'wakê or Kaiiontwa'kon in the Seneca language and thus generally known as Cornplanter, was a Dutch-Seneca war chief and diplomat of the Wolf clan. As a chief warrior, Cornplanter fought in the French and Indian War and the American Revolutionary War. In both wars, the Seneca and three other Iroquois nations were allied with the British. After the war Cornplanter led negotiations with the United States and was a signatory of the Treaty of Fort Stanwix (1784). He helped gain Iroquois neutrality during the Northwest Indian War.
