The Monroe Doctrine was a policy initiated by President James Monroe in 1823 that aimed to limit European colonial expansion in the Western Hemisphere. It declared that further efforts by European nations to colonize land or interfere with states in North or South America would be viewed as acts of aggression requiring U.S. intervention. While originally intended to discourage European influence over former Spanish colonies, it established the principle that the Americas were under the U.S. sphere of influence and off limits to future European colonization.

2. The Monroe Doctrine was an American
diplomatic decision which greatly inf luenced the
world and the way it has developed to present day. It
was a policy initiated by President James Monroe
which aimed to limit European expansion into the
Western Hemisphere. Monroe proclaimed, "the
American continents, by the free and independent
condition which they have assumed and maintain, are
henceforth not to be considered as subjects for future
colonization by any European powers.“ The US
accepted the responsibility of being the protector of
independent Western nations and affirmed that it
would steer clear of European affairs.

3. The monroe doctrine is the declaration by
President James Monroe, on december 2. 1823 that
consisted in the United States would not tolerate a
European nation colonizing independent nation in
North or South America. Any such intervention would
be considered a hostilc act by United States. Though
United States would respect existing European
colonies in Western Hemisphere.

4. The original thrust of the Monroe Doctrine was to
discourage Europeans from attempting to assert
control over Spanish colonies. The British supported
the United States doctrine, which ultimately promoted
their domination of shipping in the Atlantic Ocean.
Although Latin America was the principal object of the
Monroe Doctrine, the immediate cause for the
declaration of the Monroe Doctrine was a Russian
attempt to limit access to the northwestern region of
North America.

5. The most important causes of the declaration of
Monroe Doctrine:
1. Prevent any attempt of settling or recovery of the
colonies in Western Hemisphere. In the message we
read: “… the American Continent, for the free and
independent condition that they have assumed and
they support, they will not be considered to be in
forward subjects to future settling”.
2. To make clearly established so called “doctrine of
both spheres” and the warning to Europe of which it
is kept inside his sphere”.

6. Latin America
According to the United States state deparment, the
essence of the Monroe doctrine was based on three
principles: separate spheres of influenced for Europe and The
Americas, non-intervention and non-colonization.
The declaration stated that United States would not
interfere in European affairs and it expected that Europe
would not become involved anywhere in South
America, with the exception of colonies still under European
jurisdiction.

7.  Do not creat new colonies in America, all
the American countries are free and
independent and they can not be subject
to European domination.
 The intervention of Europe can not exist
in the internal affairs of the American
countries.
 US would not intervene in conflicts
relating to European countries, such as
the wars and colonies.

8. The most important consecuence was the creation
of the both sphere's theory, since its creation they
began to talk about the doctrine of "America for the
Americans" or rather sacastically "America for the
North-Americans". It indicated the birth of diplomacy
properly North-American, proof from the capture of
conscience inmediatelly later of the revolutionary
events. It managed to stop a double threat: The one of
the Russians thar were trying to spread each othe over
the coast of the Pacific and to exclude all the foreing
ships to the north and the one of the Holly Alliances’

9. powers capable to help Spain with its Americans
possesions.
The doctrine was recieved with enthusiasm in the
USA but in Europe it caused certain
exasperation, because since diverse historians have
proved Europe did not have any intentions of
intervening in the Spanish America. The real history
of the doctrine began in the 19th century.

10. Back in 1823, U.S. President James Monroe, in an
address to his country’s Congress, argued that the
Americas should be free of European intervention, and
that if a European power should try to interfere in or
further colonize states in the Western
hemisphere, then the U.S. would have no choice but to
intervene. This sealed U.S. hegemony over the
continent and marked an isolation from European
affairs (or problems, as they were mainly seen).

11. The Monroe Doctrine continued to dominate the
U.S. vision throughout the Cold War, as it couldn’t risk
losing its hegemony, let alone having socialist
uprisings in its "backyard." Scholars argue that the
Monroe Doctrine is no more, as the post-Cold War
era, without a "red scare," doesn’t require intervention
in Latin America and the Caribbean. In fact, U.S.
attention has shifted almost completely to the Middle
East and the fight against terrorism, reinforcing
Michael Reid’s term "the forgotten continent": Latin
America and the Caribbean now holds nothing of
particular interest.
