The First Continental Congress of the United Colonies of North America met here from September 5 to October 26, 1774, as the Pennsylvania State House (Independence Hall) was being used by the moderate Provincial Assembly of Pennsylvania. It was here that Congress resolved to ban further imports of slaves and to discontinue the slave trade within the colonies, a step toward phasing out slavery in British North America. The building has a long history as an assembly place and has been the home to numerous tenants in the arts, sciences and commerce. The meeting hall served as a hospital for both British and American troops in the Revolutionary War, and other institutions in Philadelphia have held meetings in Carpenters' Hall, including Franklin's Library Company of Philadelphia, the American Philosophical Society, and the First and Second Banks of the United States. The federal Custom House in Philadelphia was located at Carpenter's Hall between 1802 and 1819, save for a brief interruption between January and April, 1811.
