The fourth Treaty of Prairie du Chien was negotiated between the United States and the
Santee Sioux
agreed to abide by the 1830 Treaty of Prairie du Chien. The US government announced the treaty and its numerous adherents on February 24, 1831.
In this treaty, the tribes agreed to land cession of three large tracts of land: two strips of land 20 miles wide each on either side of the boundary established by the first (1825) Treaty of Prairie du Chien (roughly from
Rock River, down the Missouri River and back to Kansas City. Additional tribes later ceded the large triangular tract as the Platte Purchase
in 1836.
The treaty also established the
fur trappers
and their Native American women companions from several involved tribes. Without this provision, the mixed-race descendants were often kept from being allocated land on newly established reservations, and were caught between cultures.
