🏆 Treaty That Created Minnesota — Site of the 1851 Treaty of Traverse des Sioux that opened southern Minnesota to settlement
Traverse des Sioux State Park preserves the site of the historic 1851 Treaty of Traverse des Sioux — the single most consequential treaty in Minnesota history. Here, the Dakota people ceded 24 million acres of southern Minnesota to the U.S. government for $1,665,000 in annuity payments — approximately 7 cents per acre. The treaty opened southern Minnesota to Euro-American settlement and led directly to statehood in 1858. Within 11 years, broken treaty promises would ignite the U.S.-Dakota War of 1862. The 29-acre site includes the treaty ground, interpretive center, and the original river crossing (“traverse”) on the Minnesota River.

Frequently Asked Questions
Was the treaty fair?
By any measure, no. The Dakota ceded 24 million acres for $1.665 million — and much of that money went to traders to settle debts rather than to the Dakota people. The broken promises of this treaty were a direct cause of the 1862 U.S.-Dakota War.
