Come visit me here in Columbus in the Summer time. I will take you to the Chillicothe mounds of the ancient Hopewell Culture and afterwards we can see the Alan Eckert's production of "Tecumseh" at the open air Sugarloaf Ampitheater. Time permitting we could also visit the famous Serpent Mound in Adams county just southwest of Chillicothe.
As for the Iroquis...the fact that they were "farmers" is profoundy significant. The vast majority of Native American Cultures were horticultural or hunter gatheror cultures. From an anthropological view point that the Iroquois were an agricultural society is hugely significant. They were also a very egalitarian culture as you pointed out and that the Iroquois version of Democracy was significantly more influential to our founding fathers than the Greek version. Here's another fact about the Iroquois that most people don't know. It was a matrolineal society. The men held all positions of political power but all land, material property and familial descent were controlled by the women. If a child was born, it's family name was derived from the mother and not the father. The advantage of that is that there is no such thing as an illegitimate child. If a woman was to die, all her property was inherited by her daughters. Not only did this give Iroquois women extraordinary influence for that time, they also had the franchise.
The Iroquois also ran circles around the other tribes militarily and shortly after the beginning of their confederacy they wiped out the very powerful Huron confederacy. The Iroquois League was also extremely influential in the Seven Years War in North American (known as the French and Indian war) for if the Iroquois had sided with the French during that war our entire nations history would have been unalterably changed as the British would have probably been pushed out of the North American continents and our National Language would now be French.
I'd strongly recommend reading the historical novel by Allen Eckert "The Wilderness Empire". He's not a professional historian but he writes in a manner of using narrative dialogue which obtains from both primary and secondary sources which he meticulously footnotes and a complete bibliography of sources. So if the book appeals to you can use it's bibliography to study his source material. This is a serious good read as are all of the books in Eckert's "Winning of America" series.

Thanks for the great intel.
I was thinking about you as I learned about all the burial mounds and indigenous people's archeological sites in Ohio and the Midwest.
These were real civilizations beyond what I previously understood, and need to take their place in world history as true human civilizations.
