In 1492 Columbus rediscovered a land populated by savage stone age natives continually engaged in genocidal warfare against their neighbors. Four hundred years later as the American frontier closed, the savagery and genocidal aspects of the natives was no more but they were still stone age having never in four centuries figured out how to copy and make anything of the Europeans.
Absolutely not true. The “Civilized” nation of the Southeast began chaging their way of life almost as soon as they made contact with the the whiles. White traders from Charleston exchanged goods with the indians all the way into what is now Oklahoma, and intermarried with them. The Chickasaw indians were allies with the England against the French and then with the Americans. a company of Chickasaw fought along with the whites at Fallen Timbers. The lifestyle of all these indians was deeply affected by all these contacts, pretty much as the Scottish highlanders were by the lowlanders. The Cherokee were driven out of Georgia because they were competitors for lands they exploited pretty much the same was as the whites. Now the Comanche were indeed fierce,really “wild” indians but hey were certainly not much like their ancestors, they came down from the mountains onto the plains and became the horse indians nonpariell. In many respects they resembled the Mongol warriors of the Eurasian steppes.
