Constitution & Citizenship Day
September 17 commemorates the signing of the United States Constitution on September 17, 1787. On this day in Philadelphia, Pennsylvania, the delegates of the Constitutional Convention came together and signed one of the most important documents in American history. To this day, the U.S. Constitution is the oldest written document still in operation. This living document defines the structure of the federal government, the Bill of Rights, and the rights of states within the union.
