The final draft of the U.S. Constitution was signed in Philadelphia on September 17, 1787. Although it would be almost a year before the Constitution was ratified by the required nine states, this date marks a milestone in our country's history. On this date, the core principles guiding the United States were laid out in a single document. Learn more about the Constitution on the Virtual Reference Desk.
