When Wisconsin & Michigan disputed their border

by Jan Schroder

While we only typically see them battle on the college football field, did you know that, for nearly 20 years, Wisconsin had a squabble with its neighbor to the East about their shared border?

Wisconsin has a border with Michigan alongside that state’s Upper Peninsula, which was established as the eastern branch of the Montreal River in an 1847 survey. But in 1908, Michigan revised its Constitution and claimed the border was actually the western branch of the Montreal River.

It took all the way until 1926 for the Supreme Court to rule, but they did in favor of Wisconsin.
