Theodore Roosevelt invoked the so-called Roosevelt Corollary to the Monroe Doctrine in reaction to German and British actions against Venezuela, known as the Venezuela Crisis (1902-1903).

The Roosevelt Corollary was an addition to the Monroe Doctrine. It stated that no European countries were allowed to intervene in Latin American affairs. The only way that the U.S was allowed to become involved was if the affairs or European countries was threatened. The United States could exercise police power in Latin America. The United States was the only country allowed to interfere with Latin American countries.
