On December 2, 1823, President James Monroe introduced The Monroe Doctrine during his seventh annual address to Congress. In the doctrine, Monroe warned European powers not to interfere in the affairs of the Western Hemisphere. He declared the United States will no longer tolerate further colonization in the West and the Doctrine became an essential aspect U.S. foreign policy. The Monroe Doctrine has been invoked repeatedly throughout history in various Latin American affairs such as in the 1962 Cuban Missile Crisis.
