Delaware was the first state to ratify the U.S. Constitution, a milestone in the history honored by America250.
Delaware’s convention approved ratification on December 7, 1787, making it the first of the thirteen states to accept the new Constitution. The state later became known by the nickname “The First State,” a title reflected in its history and public identity.
The Constitution had been signed in Philadelphia on September 17, 1787, but signing by delegates did not itself establish the new government. Article VII required ratification by nine states before the Constitution could take effect among the ratifying states.
Pennsylvania was second to ratify, followed by New Jersey. Virginia and New York were especially important later ratifications because of their size and political influence. Delaware’s early decision helped give momentum to the process.
