United States Constitution

The United States Constitution is the supreme law of the United States of America. It was adopted in its original form on September 17, 1787, by the Constitutional Convention in Philadelphia, Pennsylvania, and later ratified by conventions in each state in the name of "the People." The Constitution has a central place in American law and political culture. The U.S. Constitution is the oldest written national constitution except possibly for San Marino's Statutes of 1600, whose status as a true constitution is disputed by scholars. An engrossed copy of the document is on display at the National Archives in Washington, D.C.
