Monroe Doctrine Timeline
(December 2, 1823 – Present)The Monroe Doctrine was a cornerstone of American foreign policy, first articulated by President James Monroe in 1823. It declared that the Western Hemisphere was off-limits to further European colonization and that any European interference in the Americas would be viewed as an act of aggression. Over time, the doctrine shaped U.S. relations with Latin America, influenced later policies like the Roosevelt Corollary, and remains a significant element in discussions of hemispheric diplomacy.
