The Treaty of Paris formally ended the American Revolutionary War in 1783.
Representatives of Great Britain and the United States signed the treaty on September 3, 1783. Britain recognized the United States as an independent nation and accepted boundaries extending west to the Mississippi River, north to the Great Lakes, and south to Spanish Florida.
The treaty came after the Declaration of Independence by more than seven years. The Declaration announced the colonies’ separation from Britain, but it did not end the fighting. The peace agreement established the legal framework for the new country’s international independence.
The Treaty of Ghent ended the War of 1812, not the Revolution. The Treaty of Versailles ended World War I, while Jay Treaty was a later 1794 agreement dealing with unresolved disputes between the United States and Britain. The 1783 treaty is therefore the key diplomatic endpoint of the founding war.
