Who presided over the 1787 Constitutional Convention that produced the United States Constitution?

George Washington presided over the 1787 Constitutional Convention that produced the United States Constitution.

Washington was unanimously chosen as president of the convention when it reached a quorum in Philadelphia on May 25, 1787. His military reputation and status as a Virginia statesman gave the proceedings authority, while his chairmanship helped maintain order during months of debate and negotiation.

Washington generally did not lead the detailed arguments in the way James Madison did, but he closely observed the discussions and supported creating a stronger federal government. His presence also reassured delegates and the public that the convention was a serious national undertaking rather than a routine meeting to revise the Articles of Confederation.

Washington signed the Constitution on September 17, 1787, and later became the first president under it. This creates a common mix-up with Benjamin Franklin, who was the convention's oldest delegate and a prominent advocate for compromise, or with Madison, who is often called the “Father of the Constitution” for his intellectual and drafting contributions.
