John Jay signed the 1783 Treaty of Paris alongside John Adams and Benjamin Franklin as an American peace commissioner.
The treaty was signed in Paris on September 3, 1783, by representatives of the United States and Great Britain. The American signers were John Adams, Benjamin Franklin, John Jay, and Henry Laurens, although Laurens signed the preliminary articles rather than the definitive treaty. David Hartley signed for Britain on behalf of King George III.
The treaty formally ended the American War of Independence and recognized the United States as free, sovereign, and independent states. It also established boundaries, granted American fishing rights in specified waters, and addressed debts, property, and prisoners of war.
John Jay later became the first Chief Justice of the United States. He is sometimes omitted from simplified accounts of the treaty because Franklin, Adams, and Jefferson are more widely associated with diplomacy during the Revolution; Jefferson was appointed a commissioner but did not participate in the negotiations.
