USA HISTORY

Detailed explanation-1: -The Monroe Doctrine is the best known U.S. policy toward the Western Hemisphere. Buried in a routine annual message delivered to Congress by President James Monroe in December 1823, the doctrine warns European nations that the United States would not tolerate further colonization or puppet monarchs.

Detailed explanation-2: -The Monroe Doctrine was drafted because the U.S. government was worried that European powers would encroach on the U.S. sphere of influence by carving out colonial territories in the Americas.

Detailed explanation-3: -As Monroe stated: “The American continents … are henceforth not to be considered as subjects for future colonization by any European powers.” Monroe outlined two separate spheres of influence: the Americas and Europe. The independent lands of the Western Hemisphere would be solely the United States’ domain.
