The Monroe Doctrine
The policy developed by President Monroe that warned Europe to keep out of American affairs is known as the Monroe Doctrine. Established in 1823, it asserted that any intervention by European nations in the Americas would be viewed as an act of aggression, prompting the U.S. to respond. This doctrine was significant in shaping U.S. foreign policy and asserting its influence in the Western Hemisphere.
