In 1786, Morris was one of five Pennsylvania delegates selected to attend the Annapolis Convention, where delegates discussed ways to reform the Articles of Confederation. Though Morris ultimately declined to attend the convention, the delegates convinced Congress to authorize a convention in Philadelphia in May 1787 to amend the Articles. The Pennsylvania state legislature sent a delegation consisting of Morris, James Wilson, Gouverneur Morris, George Clymer, Thomas Mifflin, Jared Ingersoll, and Ben Franklin to the Philadelphia Convention. With the exception of Franklin (who avoided aligning with either political faction in Pennsylvania), all of the Pennsylvania delegates were closely aligned with Morris's Republican faction, a reflection of Republican strength in the state legislature. Many of Morris's Nationalist allies from other states, including Hamilton, James Madison, John Dickinson, and Washington, would also attend the convention.
