The six nations, the longest running all inclusive democracy in the world speak Iroquoian.
The creator of the democracy, DEGANAWIDAH, predicted ( because he spoke to Europeans), the coming invasion of the Europeans, and THEY figured if left for a couple more decades, the Native alliance would have taken over the whole continent, and there would have been no conquering, just like they have not been "conquered" yet, and are still sovereign.
The Europeans Deganawidah talked to ( Templars were one group for sure) of course reported back to the crown, and well, they couldn't have that road block in front of their plans for world domination, so...
Of course, the SLAVE OWNING Cherokee (GREEK DNA) and the Algonquin are all from European descent DNA wise, and white people have been found in a 7000 year old village in Florida, so this was just the latest wave really.
