This year marks the 150th anniversary of the conception of Yellow Medicine County, Yellow Medicine City, Minnesota Falls, Granite Falls, and the 25 townships. In 1803, Minnesota became part of what was then the Louisiana Purchase. By spring of 1849, what would be called the Minnesota Territory (including the Dakotas, Wyoming, and Montana) was formed from what was then Michigan, Wisconsin, and Iowa. That summer, the northern tier of townships in Yellow Medicine County was a part of what was then “Dahkota” County and the southern tier of townships in Yellow Medicine County were a part of what was them “Waubashaw” County. These were two of nine counties forming what was then Minnesota Territory. The western boundary of the State of Minnesota was set at the Red River of the North, Lake Travers, Big Stone Lake, and the Corteau des Prairie boundary between Minnesota and South Dakota. Everything to the east of this boundary was in the state of Minnesota and everything to the west was in the newly formed “Dakota Territory.”
