Objective: To analyze the importance of the Monroe Doctrine.
Monroe Doctrine – Monroe’s Legacy
 North and South America should no longer be thought of as
areas for European colonization.
 The U.S. would not interfere with European affairs, and
European countries should not interfere with the affairs of
any nation in the Western Hemisphere.
 The Monroe Doctrine became a cornerstone of
American Foreign Policy.
Three main concepts of the
doctrine—
 separate spheres of influence for
the Americas and Europe,
 non-colonization, and
 non-intervention

A cartoon
from 1914
depicting
the Monroe
Doctrine as
a wall
keeping out
the fires of
war that
were raging
in Europe.
The doctrine’s greatest extension came with Teddy
Roosevelt’s Corollary, which inverted the original
meaning of the doctrine and came to justify a policy of
intervention in South American countries to prevent
European influence.
More succinctly, the Roosevelt
Corollary promoted the United
States as the “hemispheric
policeman.”
