When was the U.S. constitution ratified?
The United States Constitution was written in 1787; however, it did not take full effect until it was ratified in 1789, when it replaced the Articles of Confederation. The requirement of ratification by nine states, set by Article Seven of the Constitution, was met when New Hampshire voted to ratify, on June 21, 1788. On July 26, 1788, New York ratified, with a recommendation that a bill of rights be appended. The vote was close—yeas 30 (52.6%), nays 27—due largely to Hamilton’s forensic abilities and his reaching a few key compromises with moderate anti-Federalists led by Melancton Smith. Opposition to ratification was led by Governor George Clinton.
