On what date did Congress ratify the Treaty of Paris that ended the American Revolutionary War?

The Confederation Congress ratified the Treaty of Paris on January 14, 1784.

The treaty had been signed in Paris on September 3, 1783, by representatives of Great Britain and the United States. It formally ended the American Revolutionary War and recognized the United States as free, sovereign, and independent. The agreement also established boundaries extending west to the Mississippi River and north to the Great Lakes region.

The American negotiators were Benjamin Franklin, John Adams, John Jay, and Henry Laurens. The British representative was David Hartley. The treaty included provisions concerning fishing rights, prisoners of war, property, and the treatment of Loyalists.

Ratification was a separate step from signing. Congress approved the treaty in Annapolis, Maryland, on January 14, 1784. The British ratification followed in April, and the ratified documents were exchanged in Paris on May 12, 1784.
