The Monroe Doctrine
The Monroe Doctrine was an early 19th-century American foreign policy position opposing European colonial intervention in the Americas, significantly shaping subsequent U.S. foreign policy for nearly two centuries.
Declared by a relatively young nation still establishing its place on the world stage, this foreign policy doctrine asserted an entire hemisphere as effectively off-limits to European colonial ambition.
Opposing European Intervention
President James Monroe articulated the doctrine in 1823, declaring American opposition to further European colonization or intervention in the Western Hemisphere.
Asserting American Hemispheric Influence
The doctrine effectively asserted the United States' interest in limiting European influence throughout the Americas, establishing an early framework for American hemispheric foreign policy.
Later Expansions and Interpretations
The doctrine was significantly expanded in later interpretations, including the early 20th-century Roosevelt Corollary, which asserted a more active U.S. role in regional affairs.
A Lasting Foreign Policy Influence
The Monroe Doctrine's core principles continued influencing American foreign policy toward Latin America for nearly two centuries following its original articulation.
