Meeting in Philadelphia from May 25 to September 17, 1787, the Constitutional Convention was called to revise the Articles of Confederation but instead created a new framework for the United States government. Gathering in the Pennsylvania State House, delegates confronted the failures of the existing union, including weak national powers, financial disorder, and interstate conflict. Under George Washington's presidency, they debated representation, executive power, the judiciary, and slavery, with the Connecticut Compromise proving crucial to progress. The final Constitution, signed by 39 of 55 delegates, established the basis of a federal government and launched the struggle for ratification in the states.
