The Olney Corollary, also known as the "Olney interpretation" or "Olney declaration" was United States Secretary of State Richard Olney's interpretation of the Monroe Doctrine when the border dispute for Guayana Esequiba occurred between the British and Venezuelan governments in 1895. Olney claimed that the Monroe Doctrine gave the U.S. authority to mediate border disputes in the Western Hemisphere. Olney extended the meaning of the Monroe Doctrine, which had previously stated merely that the Western Hemisphere was closed to additional European colonization. The statement reinforced the original purpose of the Monroe Doctrine, that the U.S. had the right to intervene in its own hemisphere and foreshadowed the events of the Spanish–American War three years later. The Olney interpretation was defunct by 1933.
