The Monroe doctrine

(Politics) a policy enunciated by President Monroe (Message, Dec. 2, 1823), the essential feature of which is that the United States will regard as an unfriendly act any attempt on the part of European powers to extend their systems on this continent, or any interference to oppress, or in any manner control the destiny of, governments whose independence had been acknowledged by the United States.
