Which treaty formally ended the American Revolution and expanded U.S. borders by ceding lands from Atlantic to Mississippi and from the Great Lakes to Florida?

• A. Treaty of Paris 1783
• B. Treaty of Paris 1763
• C. Treaty of Ghent
• D. Treaty of Versailles

Answer: (A)

Understanding which agreement formally ended the American Revolution and defined the new borders is the focus here. The Treaty of Paris of 1783 fits this description: it acknowledged American independence and set the United States’ boundaries as stretching from the Atlantic Ocean to the Mississippi River and from the Great Lakes down to Florida, with Britain agreeing to withdraw its troops. It also addressed postwar issues like debts and loyalists.

This isn’t the treaty that ended the Seven Years’ War, which is why that other option doesn’t fit. It also isn’t the treaty that ended the War of 1812 or the treaty that ended World War I, so those do not match the event or the time period in question.
