 The "frostbitten constitutional convention" was held at Ann Arbor, the county seat, in 1835.Statehood was delayed because Michigan claimed the Toledo Strip, which was also claimed by Ohio.Following resolution of the Toledo War (1835-1836), in which Michigan Territory ceded its claim to Toledo in exchange for most of the Upper Peninsula (from the Porcupine Mountains eastward), Ohio withdrew its objection and Michigan became a state on January 26, 1837.
