The dispute culminated in what has become known as the Toledo War, as Michigan and Ohio militia took up arms in the area. As a condition for entering the Union, Michigan was forced to accept the eastern three-quarters of the Upper Peninsula in exchange for ceding its claim to the Toledo Strip. After a state convention first rejected this condition, a second convention, assembled under some duress in December 1836, reluctantly accepted the terms and Michigan became the 26th state on January 26, 1837, with Detroit as its first capital.
