What history would that be?,the native indians weren't civilized to any degree to document their heritage ,it was the Europeans who brought animals,varieties of food and weapons to the indians in teaching them to become more efficient in every day life, in hunting and to become better warriors in fighting battles amongst other tribes,etc. As for the 90 mil census of the 1400's,that no doubt would be the European population,as there simply wasn't any documentation recorded by the indians and when a census was conducted and documented by the 1500's, it's was by the Europeans and by that time half(speculation) of the american indians died from starvation, fighting and from disease's. Other than pure speculation,I don't think anyone to this day knows the true Indian population of that time period.
I'm not trying to start another thread battle over who is right and who is wrong, but I'll have to, slightly, disagree with you on that one. Just because they did not right their history down in books, as Europeans did, does not mean they had no type of documentation.
They used verbal history telling and certain bead work. Now, I do agree the census of Native Americans is unknown. But considering the number of tribes, there were quite a lot of people. However, they did not breed as we did or destroy their land.
And the Native American was the one who taught us to fight better. The English warfare of the time was quite precise and ritualistic. Men would form a line abreast each other and were commanded by their officers. Absolutely no small unit leadership. Unlike the Native Americans, who introduced, quite to the English surprise, something called "Guerrilla Warfare". Fighting from behind trees, movement and cover, using small groups instead of 30 men online. Now a staple in many countries tactics. You way want to refer to the withdraw of British troops, under Lt Col Smith, from Concord, retreating back to Boston and a place called "The Bloody Curve". Perfect example of what the Native Americans taught us.
Not to mention how to farm in more efficient ways, hunt wild game (which was not an active activity of the peasant English) and survival in this country. The UK had nothing in comparison to our forests at the time and most Europeans were not well versed in forest survival. Vast wilderness was very new to the settlers. As well as so many different types of flora and fauna.
The British brought disease, religion and guns, yes.
The Americas produced tobacco, potatoes and corn, to name a few.
You way also want to read up on the 5 Nations of the Iroquois Confederacy and how they influenced our founding fathers and their government. The Iroquois league is said to go back to the 12th century.
I hold a bachelors in Early American History from the University of Maryland. So I am not just saying this without backing and fact.
