The first state to ratify the Constitution was Delaware on December 7, 1787
The journey to ratification was a long and arduous process. The country was governed by the Articles of Confederation until the new Constitution was ratified. The document was tailored to a newly formed nation made of states acting more like independent, sovereign countries. It became clear to some of America’s leaders that future stability required a stronger, more centralised government. New York’s Alexander Hamilton thus led the call for a constitutional convention to reevaluate the nation’s governing document.
On June 21, 1788, the Constitution became the official framework of the government of the United States of America when New Hampshire became the ninth of 13 states to ratify it. The Constitution was subsequently ratified by Massachusetts, Maryland, South Carolina, and, finally, New Hampshire. After ratification, Congress set dates for the first federal elections and the official implementation of the Constitution.

The Constitution was subsequently ratified by Massachusetts, Maryland, South Carolina, and, finally, New Hampshire, which became the ninth state to ratify it on June 21, 1788. After ratification, Congress set dates for the first federal elections and the official implementation of the Constitution. Elections were set to take place from December 15, 1788, to January 10, 1789, and the new government was set to begin on March 4, 1789. In the nation’s first presidential election, George Washington was elected President and John Adams was elected Vice President.
Some states voiced opposition to the Constitution on the grounds that it did not provide protection for rights such as freedom of speech, religion, and the press. However, the terms of the Massachusetts Compromise reached in February 1788 stipulated that amendments to that effect—what became the Bill of Rights—would be immediately proposed. Madison introduced 17 amendments to the Constitution, of which Congress adopted 12 on September 25, 1789, to send forth to the states for ratification. Ten of those amendments, known as the Bill of Rights, were ratified on December 15, 1791.
