The Monroe Doctrine was a U.S. foreign policy principle established in 1823, which declared that the Americas should be free from European colonization and interference. It was rooted in the belief that the Western Hemisphere was separate from European politics and asserted that any attempts by European nations to extend their influence in the Americas would be viewed as acts of aggression. This doctrine was significant in shaping U.S. foreign relations and American nationalism during a period marked by the American Enlightenment.
