On September 17, 1787, delegates to the Constitutional Convention signed the United States Constitution in Philadelphia.
The document established the structure of the federal government and defined the relationship among its three branches: legislative, executive, and judicial.
It was written to replace the Articles of Confederation, which had created a national government that was too weak to address many of the challenges facing the new country.
The Constitution begins with the words “We the People” and remains the foundation of the United States government.
