A meeting called by the state of Virginia held in Annapolis, Maryland, in September 1786 to which all 13 states were asked to send delegates. The purpose of the meeting was to discuss the commercial problems besetting the United States under the Articles of Confederation. Only five states attended; the delegates requested another convention to address the problems of the Confederation. The Confederation Congress endorsed this request. Twelve states sent delegates to Philadelphia in 1787 to attend the Constitutional Convention that produced the United States Federal Constitution.
