What happened

What happened

On June 3, 1825, William Clark, Superintendent of Indian Affairs, signed a treaty at St. Louis with the chiefs, head men and warriors of the Kansas Nation.

The Kansas ceded "all the lands lying within the State of Missouri" to which they had title or claim. They also ceded the lands they occupied or claimed west of Missouri. The boundary began where the Kansas River enters the Missouri. It ran north to Missouri's northwest corner, west to the Nodewa River, then to the Big Nemaha and its source, and on to the source of the Kansas River.

From that cession the treaty reserved a tract for the Kansas. It began twenty leagues up the Kansas River, included their village there, and was thirty miles wide. The United States agreed to pay $3,500 a year for twenty years. It promised 300 cattle, 300 hogs, 500 fowls, three yoke of oxen and two carts, along with a blacksmith. Thirty-six sections of good land on the Big Blue River were to be sold to fund schools for Kansa children.

Article 6 made reservations for people of mixed ancestry. The Statutes at Large record a proclamation on December 30, 1825. The treaty text does not state the acreage.
