Which policy declared in 1823 that European powers should not colonize or interfere with independent nations in the Western Hemisphere?

• A. Embargo Act
• B. Monroe Doctrine
• C. System of checks and balances
• D. Navigation Acts

Answer: (B)

The main idea here is a declaration of U.S. hemispheric policy that shields newly independent nations in the Americas from European colonization and interference. The Monroe Doctrine, proclaimed in 1823 by President James Monroe, warned European powers to keep out of the Western Hemisphere, while also signaling that the United States would not meddle in European affairs. This came as many Latin American nations had recently won independence, and there were concerns about European monarchies trying to reassert control. The doctrine established a guardrail: the Americas were essentially off-limits for colonization, and any European intervention would be seen as a threat to the United States. In practice, it shaped U.S. foreign policy for generations, even though enforcement depended on later American power. The other options refer to different policies—trade restrictions, government structure, and colonial-era trade laws—that do not address the question of keeping European powers out of the Western Hemisphere.
