<P> The Constitutional Convention ( also known as the Philadelphia Convention , the Federal Convention , or the Grand Convention at Philadelphia ) took place from May 25 to September 17 , 1787 , in the old Pennsylvania State House ( later known as Independence Hall because of the adoption of the Declaration of Independence there eleven years before ) in Philadelphia , Pennsylvania . Although the Convention was intended to revise the league of states and first system of government under the Articles of Confederation and Perpetual Union , which were first proposed in 1776 , adopted by the Second Continental Congress in 1778 and only finally unanimously ratified by the Original Thirteen States by 1781 ) , the intention from the outset of many of its proponents , chief among them James Madison of Virginia and Alexander Hamilton of New York , was to create a new government rather than fix the existing one . The delegates elected George Washington of Virginia , former commanding general of the Continental Army in the late American Revolutionary War ( 1775 - 1783 ) , to preside over the Convention . The result of the Convention was the creation of the Constitution of the United States , placing the Convention among the most significant events in the history of the United States and indeed of worldwide historical , political and social influence . </P>
