What is "canasatego"

Canassatego (c. 1684–1750) was a leader of the Onondaga nation who became a prominent diplomat and spokesman of the Iroquois Confederacy in the 1740s. He was involved in several controversial land sales to British American officials. He is now best known for a speech he gave at the 1744 Treaty of Lancaster, where he recommended that the British colonies emulate the Iroquois by forming a confederacy. He was reportedly assassinated, perhaps by sympathizers or agents of New France.
