I believe the Sioux kicked the Crow, Kiowa, Blackfeet, and others off the land that we eventually took from them.
It’s the history of man.
Also, what is overlooked in regard to treatment of Native Americans is that in Florida, Natives were given the opportunity to stay if they agreed to abide by state laws. Thus started the forced migration west and onto reservations.
The US did not treat Natives kindly, but they were very good at picking the wrong side of wars involving the US and also killing innocent and isolated settlers.
Comparatively, the Natives here were treated much better during the same time period, if you compare to South America, Europe, Africa and Asia.
