It’s hard to imagine it now, but two states once fought over Toledo, and a third state lost hundreds of square miles of wilderness because of that spat. In the early 1800’s, the four territories of Wisconsin, Michigan, Indiana and Ohio were getting close to achieving statehood. At that time the legal threshold to become a state was a population of 60,000 and of the four, Wisconsin was the last to achieve that mark.
Michigan wrangled with Ohio over the location of Michigan’s southern border, and at stake was the determination of which future state would claim Toledo. As a thriving port city, Toledo was key to Ohio’s movement of commerce. After much wrangling, during which each side actually armed themselves and prepared for war, a compromise was finally reached and the border was located far enough north that Toledo officially became a part of the new state of Ohio.
Since Michigan had made the concession on its southern border Congress compensated them by giving them the Upper Peninsula. Wisconsin objected, of course, because that land was attached to their territory, but short of the population numbers necessary to become a state Wisconsin had no say in the matter and the borders were redrawn.
