In his December 2, 1823, address to Congress, President
James Monroe
articulated United States' policy on the new political order developing in the
rest of the Americas and the role of Europe in the Western Hemisphere.
President James Monroe
The statement, known as the Monroe Doctrine, was little noted by the Great Powers
of Europe, but eventually became a longstanding tenet of U.S. foreign policy.
Monroe and his Secretary of State
John Quincy Adams
drew upon a foundation of American diplomatic ideals such as disentanglement
from European affairs and defense of neutral rights as expressed in Washington's
Farewell Address and Madison's stated rationale for waging the
War of 1812. The three main
concepts of the doctrine--separate spheres of influence for the Americas and
Europe, non-colonization, and non-intervention--were designed to signify a clear
break between the New World and the autocratic realm of Europe. Monroe's
administration forewarned the imperial European powers against interfering in
the affairs of the newly independent Latin American states or potential United
States territories. While Americans generally objected to European colonies in
the New World, they also desired to increase United States influence and trading
ties throughout the region to their south. European mercantilism posed the
greatest obstacle to economic expansion. In particular, Americans feared that
Spain and France might reassert colonialism over the Latin American peoples who
had just overthrown European rule. Signs that Russia was expanding its presence
southward from Alaska toward the Oregon Territory were also disconcerting.
For their part, the British also had a strong interest in ensuring the demise of
Spanish colonialism, with all the trade restrictions mercantilism imposed.
Earlier in 1823 British Foreign Minister George Canning suggested to Americans
that two nations issue a joint declaration to deter any other power from
intervening in Central and South America. Secretary of State
John Quincy
Adams, however, vigorously opposed cooperation with Great Britain,
contending that a statement of bilateral nature could limit United States
expansion in the future. He also argued that the British were not committed to
recognizing the Latin American republics and must have had imperial motivations
themselves.
British Foreign Minister George Canning
The bilateral statement proposed by the British thereby became a unilateral
declaration by the United States. 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. In exchange, the
United States pledged to avoid involvement in the political affairs of Europe,
such as the ongoing Greek struggle for independence from the Ottoman Empire, and
not to interfere in the existing European colonies already in the Americas.
By the mid-1800s, Monroe's declaration, combined with ideas of Manifest Destiny,
provided precedent and support for U.S. expansion on the American continent. In
the late 1800s, U.S. economic and military power enabled it to enforce the
Monroe Doctrine. The doctrine's greatest extension came with
Theodore Roosevelt's
Corollary, which inverted the original meaning of the doctrine and
came to justify unilateral U.S. intervention in Latin America.
