Ohio Admitted as 17th State
Ohio became the 17th state admitted to the Union, the first state carved from the Northwest Territory. Ohio's admission demonstrated the success of the Northwest Ordinance of 1787, which established the process for creating new states from western territories.
Why It Matters
Ohio's statehood validated the constitutional framework for admitting new states on equal footing with the original thirteen, proving that the republic could grow while maintaining democratic principles.
