What date did the Treaty of Paris of 1783 formally end the American Revolutionary War?

The Treaty of Paris of 1783 was signed on September 3, 1783, formally ending the American Revolutionary War.

Representatives of Great Britain and the United States negotiated the treaty in Paris. Britain recognized the former Thirteen Colonies as free, sovereign, and independent states. The agreement also established American boundaries extending west to the Mississippi River, south to Spanish Florida, and north toward the Great Lakes.

The military surrender at Yorktown in October 1781 was a decisive victory, but it did not itself create a final peace settlement. Preliminary articles were agreed in 1782, while the definitive treaty was signed in 1783. It became effective after ratification and later exchanges of ratified documents.

The Treaty of Paris is distinct from the Peace of Paris as a whole, which included separate agreements involving Britain, France, Spain, and the Dutch Republic. Its recognition of American independence made it a foundational milestone on the road to the United States’ 250th anniversary.
