2 déc. 1823 - Monroe Doctrine

Description:

The Monroe Doctrine, articulated in 1823 by President James Monroe during his annual message to Congress, declared that the Americas should be free from future European colonization and free from European interference in sovereign countries' affairs. This policy became a cornerstone of American foreign policy, asserting U.S. influence in the Western Hemisphere and marking a defining moment in the nation's emergence as a world power.
