It was organized in 1879 and named after an early settler, Louis Huot, whose last name also was affixed to a small settlement within the township known as Huot. A large percentage of the township population was French or French-Canadian. The primary economic activity has always been agriculture. The townsite of Dorothy and the Old Crossing Treaty State Park at Huot are the only non-agricultural features of the township.
