They literally got fucked in the ass when this land got invaded.
Back when it happened, sure. Ever since then, not so much.
The point being that no one who was on either side of that deal is alive today. It's history. I'd also note that the culture appears to have been stagnant. I said "appears" because my knowledge of the American Indian tribes is limited. I based that thought on the biases of them being not much further advanced than hunter gatherers. I could very well be wrong.
