The United States Constitution
is the law of the United States of America. It was adopted 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"; it has since been amended seventeen times, minus the 10 added through the Bill of Rights. The Constitution has a central place in United States law and political culture. The U.S. Constitution is argued by many to be the oldest written national constitution. The handwritten, or "engrossed", original document is on display at the National Archives and Records Administration in Washington, D.C. The United States Constitution has 4,543 words, including the signatures.
