On December 7, 1787, Delaware was the first state to ratify the Constitution - then came Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts, Maryland, and South Carolina.

The Constitution officially took effect when New Hampshire became the ninth state to ratify it on June 21, 1788. With that decisive vote, the nation’s blueprint, written in Philadelphia, became the supreme law of the new American government - and remains so to this day.
