The Toledo War (1835-36)

Believe it or not, Michigan and Ohio once squared off over a slim strip of land containing the city of Toledo . Militias mobilized, tempers flared, and political rhetoric soared past anything that the dispute really deserved.

Fought in Texas weeks after the Confederacy had effectively collapsed, this short skirmish featured U.S. and Confederate troops battling despite the war’s official end . Confusion and poor communication kept the fighting alive.
