The Dakota Conflict of 1862

I thought that the Europeans were wrong to treat the Dakota Indians the way that they did. The Dakota Indians were on the land first so they should have the right to say what the Europeans can and can't do. I also thought that the Europeans should have kept their half of the treaty and given the Dakota food. If the Europeans would have kept their treaty, then the conflict never would have happened. I don't think that it was right for the Dakota to go and kill some settlers, but they needed food and they had to get it somehow.
