There's a huge difference, Proleg. There were no laws then, no deeds or ownership, none of that.
There were, they were just ignored. The treaties were violated, the land stolen, the people either relocated or slaughtered...all in the name of Manifest Destiny.
Considering that the King of England had given the land out before anyone ever saw it, I would say that any treaty made prior to 1776 was either illegal or England's problem.
I believe the Spaniards divvied up the Southern part of the American continent that way as well.
So?
Montana entered the union, officially becoming a state November 8,1889.
My people were not responsible for any wrongs done before then. And since, as a Salish, my people gave (had stolen from them) the 81 million acres of Montana to... my ancestors, I'm going to sit up here and laugh.
Sorry, but I find this obsession with crimes committed so long ago that no one alive was there just a bit silly.
Doesn't the world have enough current problems, without dredging up this crap?
Make sure it doesn't happen again, yes...
Lay blame for it? I'll tell you what. You show me one living person that stole land from the Indians, broke treaties with them or otherwise was responsible for the Trail of Tears, The Bitterroot March or any other hardship and I will join you in calling for legal action.
Until then, know the history, learn from it, but stop wallowing in it.
If my Grandmother, who was a full blooded Salish could get over it, everyone else can.
