September 3 is best known for 1783, when American and British diplomats signed the Treaty of Paris, formally ending the American Revolution and recognizing U.S. independence. The date also marks Britain and France declaring war on Germany in 1939 and the Viking 2 lander touching down on Mars in 1976.
The big story: The Treaty of Paris ends the American Revolution (1783)
The last major battle of the Revolution was fought at Yorktown in October 1781, but peace took nearly two more years of bargaining. Benjamin Franklin, John Adams and John Jay opened talks with the British in 1782, and on November 30 of that year both sides signed preliminary articles in Paris. The final treaty had to wait until Britain wrapped up its own settlement with France. On September 3, 1783, David Hartley signed for Great Britain, and Adams, Franklin and Jay signed for the United States. In the first article, Britain recognized the 13 former colonies as free, sovereign and independent states. The treaty also set the new nation’s borders, reaching west to the Mississippi River, and kept Americans’ rights to fish off Newfoundland. Creditors on both sides could pursue prewar debts, and Congress agreed to urge the states to return confiscated property. The Continental Congress ratified the treaty on January 14, 1784.
