The treaty that the United States signed to end the Revolutionary War is the Treaty of Paris, signed on September 3, 1783. This treaty formally recognized American independence and established borders for the new nation, granting the U.S. territory that extended from the Atlantic Ocean to the Mississippi River, and from Canada to Florida. The Treaty of Paris also addressed issues such as the rights of loyalists and the return of property seized during the war. This significant diplomatic achievement marked the end of British colonial rule in the American colonies and laid the groundwork for the United States’ future development as an independent nation.
