“This story just highlights the point that there is really no such thing as a “native” American. Some people arrived early, some later.”
Yeah, the Europeans wanted it, and they had better technology and a huge population, so they took it—as has always been done, throughout human history.
This time, though, the advent of the concept that taking people’s land is not good was nigh, so the Europeans allow the Indians to guilt trip and intimidate the snot out of them.
Never mind that the Indians were the same way; when we do it it’s baaaaaaad.
Manifest Destiny will rise again.
Here's a map of where the tribes were in 1650. A hundred years later, the Cheyenne were in Arikara & Apache territory; the Sioux had moved into the Cheyenne territory. Plenty of other stirring around had taken place.
In another 50 years, the Sioux were finally successful in driving the Cheyenne out of the Sioux's "sacred Black Hills".
I had another map, with migration arrows & dates, showing the routes & timeline, but it disappeared; but this one will do to illustrate the point.
The Commanche had one hell of a deserved reputation for nastiness in the Texas-Mexico border region. Considering they had been forced out of the Powder River/Wind River area and systematically driven to that area over a 200 year period, one might understand why they decided to not be pushed any more. There mistake was trying to push back against Texans.
