The Yankton Sioux have a long history in the Northern Plains. They signed several treaties with the United States, most notably in 1858, ceding millions of acres but securing a reservation and protection for the Pipestone Quarry.

Throughout, the Yankton Sioux have maintained their traditions and community.
