Which event in 1803 dramatically expanded U.S. territory beyond the Mississippi River?

• A. The War of 1812
• B. The French Revolution
• C. The Monroe Doctrine
• D. The Louisiana Purchase

Answer: (D)

The event is the Louisiana Purchase in 1803. The United States bought the vast Louisiana Territory from France for about $15 million, adding roughly 828,000 square miles and giving the country control of the Mississippi River and the port of New Orleans. This dramatically increased the nation's land west of the Mississippi and nearly doubled its size, opening the door to westward exploration and settlement, like the Lewis and Clark expedition. The other events listed happened later or in different contexts and did not expand U.S. territory in 1803.
