The delegates of the Annapolis Convention met in September 1786 to discuss the problems with the Articles of Confederation, the first governing document of the United States. Because the document gave no power to Congress to regulate interstate commerce, the states had erected ruinous protectionist trade barriers between themselves.
Over the course of the meeting, which lasted from Sept. 11 to Sept. 14, 1786, the delegates began to realize other important defects in the Articles of Confederation. The convention's final report called for another convention to take place in Philadelphia the following May to discuss a complete overhaul of the document. This meeting was the Constitutional Convention of 1787 that produced the U.S. Constitution.
