What happened May 1787 AD

Washington arrived in Philadelphia on May 9, 1787, though a quorum was not attained until Friday, May 25. Benjamin Franklin nominated Washington to preside over the convention, and he was unanimously elected to serve as president general. The convention's state-mandated purpose was to revise the Articles of Confederation with "all such alterations and further provisions" required to improve them, and the new government would be established when the resulting document was "duly confirmed by the several states".

Governor Edmund Randolph of Virginia introduced Madison's Virginia Plan on May 27, the third day of the convention. It called for an entirely new constitution and a sovereign national government, which Washington highly recommended.
