Constitution of the United States

A written document executed by representatives of the people of the United States as the absolute rule of action and decision for all branches and officers of the government, and with which all subsequent laws and ordinances must be in accordance unless it has been changed by a constitutional amendment by the authority that created it.

For over 200 years, the Constitution of the United States has served as the foundation for U.S. government. Created in 1787, the U.S. Constitution establishes and defines the basic outlines of a national government that joins the states in an effective political union. The U.S. Constitution has been and remains one of the most enduring political agreements in the history of the world. Throughout its existence, it has served as an inspiring example of the potential of constitutional government, causing many other countries and peoples to emulate its provisions.

According to Article VI of the Constitution, the U.S. Constitution is "the supreme Law of the Land." All other laws and judicial decisions are subject to its mandates. The Constitution therefore has higher authority than all other laws in the nation, including statutes and laws passed by Congress and state legislatures. Unlike those other laws, the Constitution may be changed, or amended, only in special ways that reflect its character as a demonstration of the people's will.

The original document of the U.S. Constitution is held at the National Archives, in Washington, D.C.
