The Constitutional Convention of 1787, also known as the Federal Convention of 1787, was the meeting at which the Constitution of the United States was debated and agreed upon. The Constitutional Convention convened on May 25, 1787, in Independence Hall in Philadelphia, Pennsylvania, where the Declaration of Independence had been adopted 11 years earlier, on July 4, 1776. Although meeting to amend the Articles of Confederation, over the summer they created a new, more centralized form of government. The new document, the Constitution, was completed September 17, 1787, and was officially adopted March 4, 1789. For more detail see United States Constitution.
One provision of the United States Constitution (Article V) that has never been used authorizes the calling of further constitutional conventions for proposing constitutional amendements upon the request of two-thirds of the states.
