This area along the St. Joseph River was settled in the colonial period by French pioneers from Quebec and France. They traded with the Potawatomi and other Algonquian-speaking tribes of the area.
After United States acquisition of this territory following the American Revolution, settlers began to enter from eastern states in the early 19th century. The original county of St. Joseph was divided by Americans into townships. Mendon township was settled in 1831. The village of Mendon was platted in 1845.
