Doctrine of the Americas

The Doctrine of the Americas, often referred to as the Monroe Doctrine, was a U.S. policy established in 1823 aimed at limiting European colonial influence in the Americas. It asserted that any European intervention in the affairs of nations in the Western Hemisphere would be viewed as an act of aggression, prompting U.S. intervention. Essentially, it signaled that the Americas were off-limits for new colonization, promoting the idea of independence for Latin American countries. This doctrine shaped U.S. foreign policy and its role in the region for many years.
