Great Sioux Reservation Trend 2026

Established by the 1868 Fort Laramie Treaty, the Great Sioux Reservation originally spanned vast lands in the Dakotas, Wyoming, and Nebraska. It serves as a sovereign homeland for the Lakota and Dakota Sioux tribes, supporting cultural preservation, governance, and community life. Today, its fragmented remnants primarily benefit enrolled tribal members, who manage resources and uphold treaty rights.
