Four years after the United States won its independence from England, 55 state delegates, including George Washington, James Madison and Benjamin Franklin, convene in Philadelphia to compose a new U.S. constitution on May 25, 1787.
The Articles of Confederation, ratified several months before the British surrender at Yorktown in 1781, provided for a loose confederation of U.S. states, which were sovereign in most of their affairs. On paper, Congress—the central authority—had the power to govern foreign affairs, conduct war, and regulate currency, but in practice these powers were sharply limited because Congress was given no authority to enforce its requests to the states for money or troops. By 1786, it was apparent that the Union would soon break up if the Articles of Confederation were not amended or replaced. Five states met in Annapolis, Maryland, to discuss the issue, and all the states were invited to send delegates to a new constitutional convention to be held in Philadelphia.
