Congress proposes an end to the Michigan/Ohio boundary issue.
After months of debate, Congress passed the Northern Ohio Boundary Bill (Clayton Act) on June 15, 1836 to resolve the ongoing boundary dispute between the state of Ohio and the Michigan Territory. Both claimed the mouth of the Maumee River (present-day Toledo) and offered surveys supporting their positions. The congressional compromise awarded Toledo to Ohio and granted Michigan the western Upper Peninsula and immediate statehood. Ohio was elated, but Michigan struggled, and eventually accepted a solution they believed was unfair.
At any rate, President Andrew Jackson signed the bill, which also included another carrot for Michigan. If Michigan agrees, it can become a state. Michigan must hold a convention, however, to approve the compromise measure.
