Of course it's about race. How "privileged" of me not to see it.
Seriously, like I said, the other map shows different lines. It was my understanding that the treaty of 1851 had been superseded bu more current treaties, due at least in part to Indian on Indian aggression. Wikipedia would seem to confirm this.
This is one of the most naive things I've seen on this forum. The treaty is "superseded", I spit out some coffee I laughed so hard.
These weren't revisions made willingly by the natives. These aren't agreements made by equal partners. These "agreements" are dictates by the Federal Government against the actual possessors of the land. Yes, 150 years ago, but that doesn't really make much of a difference.
The very idea of "indian aggression"... I dont even know what to say. White settlers nearly wiped out the actual inhabitants of the entire continent, both through deliberate action and through unintentional germ warfare. White settlers made and reneged on treaties with the natives, slowly but surely cheating them out of their land and onto tiny, barren reservations. Settlers took their lands, forced them into reservations, and never paid what they owed, and then blamed it on "indian aggression" when the natives resorted to violence in their fight for freedom. It's shocking to see this kind of revisionist statist history being spread on this forum.
Edit: Since you suggested wikipedia would support your claim...
"The United States and Dakota leaders negotiated the Treaty of Traverse des Sioux[5] on July 23, 1851, and Treaty of Mendota on August 5, 1851, by which the Dakota ceded large tracts of land in Minnesota Territory to the U.S. In exchange for promises of money and goods. From that time on, the Dakota were to live on a 20-mile (32 km) wide Indian reservation centered on a 150 mile (240 km) stretch of the upper Minnesota River.
However, the United States Senate deleted Article 3 of each treaty, which set out reservations, during the ratification process. Much of the promised compensation never arrived, was lost, or was effectively stolen due to corruption in the Bureau of Indian Affairs (then called the Office of Indian Affairs). Also, annuity payments guaranteed to the Dakota often were provided directly to traders instead (to pay off debts which the Dakota incurred with the traders)."
