Monroe Doctrine

Monroe Doctrine


The Monroe Doctrine, articulated on December 2, 1823, during President James Monroe’s seventh annual message to Congress, is a cornerstone of American foreign policy. It asserted that the Western Hemisphere was no longer open to European colonization and that any interference by European nations in the Americas would be viewed as a threat to U.S. security. The doctrine has had a lasting impact on the foreign policy and diplomatic relations of the United States.

Historical Context

  1. Post-Napoleonic Europe: After the defeat of Napoleon in 1815, European powers sought to restore their influence and control over former colonies and territories. The Holy Alliance, comprising Russia, Austria, and Prussia, aimed to suppress revolutionary movements and maintain the status quo in Europe and its colonies.
  2. Latin American Independence Movements: During the early 19th century, many Latin American countries fought for and gained independence from Spanish and Portuguese rule. The United States, sympathetic to these movements and interested in limiting European influence in the hemisphere, sought to support these newly independent nations.
  3. British Interests: Great Britain, with its powerful navy and global commercial interests, also opposed the re-colonization of Latin America by other European powers. British foreign minister George Canning proposed a joint declaration with the United States to prevent European intervention, but President Monroe and his advisors decided on a unilateral American statement.

Key Principles of the Monroe Doctrine

  1. Non-Colonization: The doctrine stated that the American continents were no longer open to future colonization by any European powers. This principle aimed to protect the sovereignty and independence of the new nations in the Americas.

    “The American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers.”

  2. Non-Intervention: Monroe declared that any attempt by European nations to extend their political system to the Western Hemisphere would be considered dangerous to the peace and safety of the United States. This principle emphasized that European powers should not interfere in the internal affairs or the independence of countries in the Americas.

    “We owe it, therefore, to candor and to the amicable relations existing between the United States and those powers, to declare that we should consider any attempt on their part to extend their system to any portion of this hemisphere as dangerous to our peace and safety.”

  4. U.S. Neutrality in European Affairs: While asserting its position in the Western Hemisphere, the United States also promised not to interfere in the internal affairs of European countries or their existing colonies.

    “In the wars of the European powers in matters relating to themselves we have never taken any part, nor does it comport with our policy to do so.”

Impact and Reception

  1. Immediate Reaction: The immediate reaction to the Monroe Doctrine was mixed. While it was largely ignored by European powers, it was positively received in Latin America. Britain, with its own interest in preventing European interference in Latin America, unofficially supported the doctrine through its naval power.
  2. Long-Term Significance:
    • Foundation of U.S. Foreign Policy: The Monroe Doctrine laid the foundation for future American foreign policy in the Western Hemisphere. It established the United States as the dominant power in the Americas and a protector of the newly independent Latin American states.
    • Roosevelt Corollary: In 1904, President Theodore Roosevelt expanded the Monroe Doctrine with the Roosevelt Corollary, asserting the right of the United States to intervene in Latin America to maintain stability and order. This extension justified numerous U.S. interventions in the region.
    • Cold War Context: During the Cold War, the Monroe Doctrine was invoked to justify U.S. actions aimed at preventing the spread of communism in the Western Hemisphere, including involvement in events such as the Cuban Missile Crisis and various interventions in Central and South America.
  3. Criticism and Controversy: While the Monroe Doctrine established a protective stance, it has also been criticized for justifying American interventionism and dominance in Latin American affairs. Critics argue that it has been used to support policies that prioritized U.S. interests over the sovereignty and welfare of Latin American countries.


The Monroe Doctrine represents a pivotal moment in American diplomatic history. It asserted a clear stance against European colonialism and intervention in the Western Hemisphere, laying the groundwork for the United States’ future role as a regional and global power. Despite its controversial applications, the doctrine’s principles have had a profound influence on the foreign policy landscape of the Americas and the broader world.
