Which of the following best describes the significance of the Monroe Doctrine?

• A. It encouraged European nations to support American independence.
• B. It established U.S. intentions to prevent European interference in the Americas.
• C. It sought to expand American territory into Europe.
• D. It was a treaty signed with England regarding border conflicts.

Answer: (B)

The significance of the Monroe Doctrine lies in its clear declaration that the Americas were no longer open to European colonization and that any interference by European powers in the affairs of the Western Hemisphere would be viewed as a threat to U.S. security and sovereignty. This doctrine, articulated by President James Monroe in 1823, was an assertion of U.S. influence in the region and served as a cornerstone of American foreign policy. It reinforced the idea that the United States would stand against any attempts by European nations to expand their power in the Americas, effectively laying the groundwork for future U.S. interventions in the region.

While the other statements include points related to international relationships, they do not accurately capture the core purpose of the Monroe Doctrine, which emphasized the principle of non-intervention and U.S. primacy in the Americas.
