The Treaty of Paris officially recognized United States independence in 1783.
Representatives of Great Britain and the United States signed the treaty in Paris on September 3, 1783. It formally ended the American Revolutionary War and acknowledged the former Thirteen Colonies as free, sovereign, and independent states.
The Declaration of Independence announced separation from Britain in 1776, but it did not itself end the war or secure British recognition. The military surrender at Yorktown came in 1781, followed by lengthy peace negotiations before the treaty was signed.
The agreement also established boundaries for the new nation, including territory extending west to the Mississippi River. The Treaty of Paris is distinct from the later Paris treaties that ended other conflicts involving the United States.
