Who was the leader of the constitutional convention

The leader of the Constitutional Convention of Philadelphia was George Washington.

Explanation:

The Philadelphia Convention was held from May 25 to September 17, 1787 in Philadelphia, Pennsylvania. It was chaired by George Washington, who two years later would become president.

Initially intended to deal with problems in the United States as a result of independence from Britain declared on July 4, 1776 by amending the Articles of Confederation, it resulted in the drafting and adoption of the Constitution of the United States still in force today. The desire of many participants, including the federalists James Madison and Alexander Hamilton, was indeed to establish a new mode of government rather than simply correcting the one established by the Articles of Confederation.
