The Confederation Congress ratified the Treaty of Paris in Annapolis on January 14, 1784. The ratification took place at the Maryland State House, where Congress was meeting during the Confederation period.
The Treaty of Paris had been signed in Paris on September 3, 1783, but signature and ratification were separate steps. The treaty recognized American independence and settled the peace terms with Great Britain. Congress's formal ratification in Annapolis completed the American side of the process and is commemorated as Ratification Day.
Annapolis was then serving as the seat of the national government, but it was not the permanent capital under the Constitution. The Confederation Congress moved among several cities, including Philadelphia, New York, and Annapolis. A related landmark is George Washington's resignation as commander-in-chief, which occurred in Annapolis in December 1783, weeks before the treaty was ratified.
