During the bloodless Toledo "war" in 1835, Michigan troops made their headquarters here as rivalry between settlers in Michigan and Ohio intensified a dispute over the contested frontier. Original U.S. surveys had placed the mouth of the Maumee River, around which Toledo was developing, in Monroe County, but when Ohio began the Miami Canal it obtained from Congress a new survey that showed those lands in Ohio. Months of unrest followed, with Ohio partisans seized on the disputed border and tried in the Monroe County Court House, while militia from both states rushed to the border but never fought. The conflict ended when Michigan accepted the Upper Peninsula in exchange for the Toledo strip of Monroe County, and Michigan was admitted to statehood in 1837.
