The Congress of the Articles of Confederation in February,1787, adopted a resolution calling for a convention of delegates from the thirteen states to be held in Philadelphia beginning in May “for the sole purpose of revising the Articles of Confederation.” Twelve of the states chose convention delegates. Only Rhode Island declined to do so. Fifty-five men attended some or all of the convention. The convention was supposed to begin on May 14 but did not do so because not enough delegates had arrived to constitute a quorum. James Madison arrived early on May 3, and he and other delegates from Virginia and Pennsylvania then met informally and prepared a new plan of government to present to the convention once it began. Finally, on May 25, enough delegates had arrived to constitute a quorum, and the convention began. The delegates unanimously elected General George Washington to preside as the President of the Convention. The delegates soon decided that instead of simply “revising the Articles of Confederation,” they would write a completely new constitution with a very different system of government from that which the nation had under the Articles.
After spending the entire summer behind closed doors in secrecy dealing with several difficult issues, on September 17, 1787, the new Constitution of the United States was completed. Thirty-nine delegates present at the end of the convention signed the Constitution. Three delegates – Edmund Randolph of Virginia, Elbridge Gerry of Massachusetts, and George Mason of Virginia—refused to sign it. The new Constitution was then sent to the states for ratification.
