( also the Iroquois Confederacy )
a union of Native-American peoples established about 1570. The groups involved, all in north-eastern America, were the Cayuga, the Mohawk , the Oneida, the Onondaga and the Seneca . The League was originally also called the Five Nations. When the Tuscarora joined in 1722, it became known as the Six Nations. Its members were farmers and hunters. They supported the British in the French and Indian War and, except for the Oneida and Tuscarora, also in the American Revolution .
