Which event occurred in 1803 to expand U.S. territory by acquiring land from France?

• A. The Monroe Doctrine
• B. The Embargo Act
• C. The Adams-Onis Treaty
• D. Louisiana Purchase

Answer: (D)

A land purchase in 1803 dramatically expanded U.S. territory, when the United States bought the Louisiana Territory from France. This deal secured control of the Mississippi River and the port of New Orleans, adding about 828,000 square miles to the country for roughly $15 million. It opened vast lands for settlement and farming, doubled the size of the United States, and paved the way for westward exploration and growth. The other events are different kinds of actions: the Monroe Doctrine was a 1823 policy about European powers in the Western Hemisphere, not a land purchase; the Embargo Act restricted American trade in 1807 without acquiring territory; and the Adams-Onis Treaty occurred later and involved ceding Florida and setting borders, not a 1803 land purchase from France.
