when was the constitution ratified written
Delaware was the first state to ratify, on December 7, 1787. After New Hampshire became the ninth state to ratify, on June 22, 1788, the Confederation Congress established March 9, 1789, as the date to begin operating under the Constitution. By this time, all the states except North Carolina and Rhode Island had ratified â the Ocean State was the last to ratify on May 29, 1790.
