There are three basic versions, classified as Great Lakes, Iroquoian, and Southern.
Today, there are altogether around 80,000 people in the US and
45,000 people in Canada who are considered to be true Iroquoian peoples.
Colonial British and French American testimonies generally referred to them as the Iroquoian Confederacy, comprised by the nations of Mohawk,
Onondaga, Oneida, Cayuga, Seneca and Tuscarora, and considered this grouping as the whole of Iroquoian culture.
