Seminar paper from the year 2005 in the subject Politics - International Politics - Region: USA, grade: 1,3, Indiana University (Political Science Department), course: American Political Traditions, 13 entries in the bibliography, language: English, abstract: The Monroe Doctrine will be 200 years old in 2023 and the world of today could not be more different than from the conditions of the world in which president James Monroe gave his speech, which would become so famous and significant for the direction of U.S. foreign policy.

Originally it attempts to keep Europeans out of the New World but it does not attack the already existing colonies in the Western Hemisphere.
