The 1787 Constitutional Convention met in Philadelphia, an event connected to the founding era remembered by America250.
Delegates assembled at the Pennsylvania State House, now called Independence Hall, from May 25 through September 17, 1787. They were initially authorized to revise the Articles of Confederation, but instead produced an entirely new framework for the federal government.
Philadelphia was already a major center of revolutionary politics. The Continental Congress had met there, and the Declaration of Independence had been adopted in the same building in 1776. The Constitutional Convention was not a gathering of every American leader: Rhode Island sent no delegates, and several prominent figures, including Thomas Jefferson, were abroad.
