Prairie du Chien Indian Agency (Wisconsin)

History
The Prairie du Chien Agency was established in 1807 to serve the Indians in Louisiana living along the Mississippi River above the Iowa River; and the Indians living in Indiana Territory north of the Illinois River and west of a line running north and south from a point on the Illinois River about 20 miles north of Peoria. The agency headquarters was located at Prairie du Chien, north of the mouth of the Wisconsin River, on the east bank of the Mississippi River.

Other agencies were formed from the area covered by this early agency -- the St. Peters Agency, the Green Bay Agency, and the Sac and Fox Agency at Rock Island, Illinois.
