The Monroe Doctrine proclaimed in 1823 stated that the United States would oppose European attempts to control territory in which region?

• A. Africa
• B. Asia
• C. Eastern Hemisphere
• D. Western Hemisphere

Answer: (D)

The Monroe Doctrine established a hemispheric boundary by declaring that European powers should stay out of the Western Hemisphere. It asserted that the Americas should not be colonized or controlled by European nations and that the United States would regard any attempt to do so as a threat to its security. This policy grew out of the era’s Latin American independence movements and aimed to deter European interference while signaling U.S. leadership in the region. The other regions listed don’t fit because the doctrine specifically targets the Western Hemisphere—the American continents—while Africa or Asia were in Europe’s sphere of more extensive colonial activity, and the doctrine was not framed as a broad statement about the Eastern Hemisphere.
