Louisville Township was settled as part of a colony of immigrants from Quebec introduced by promoter Pierre Bottineau in the 1870s. 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.
