Scott County was first inhabited by two bands of the Santee Sioux (Dakota) Indians, the Mdewakanton and Wahpeton. Their semi-nomadic life followed a seasonal cycle. They gathered food, hunted, fished, and planted corn. In the summer the Dakota villages were occupied but in the winter the groups separated for hunting. They had many permanent villages along the Minnesota River. They had many trails leading to these settlements and to the Red River Valley in the North, and the Prairie du Chien to the Southeast. These trails were later used by the fur traders and settlers, and were known as the "ox cart trails." The area of Scott County, as well as much of southern Minnesota, was opened for settlement by two treaties signed at Mendota and Traverse des Sioux, in 1851 and 1853. These treaties removed the Dakota Indians to reservations in upper Minnesota.
