(1904), foreign policy statement attached to the
Monroe Doctrine by President Theodore Roosevelt, declaring that the United States would exercise police power to maintain stability in the Western Hemisphere. Directed at Europe, the Roosevelt Corollary stated that the United States would consider any interference in the affairs of small, poor Latin American nations a violation of the Monroe Doctrine. The first application of the Corollary occurred in 1905, when Roosevelt sent Marines to the Dominican Republic to manage the country's European debts.
