What was a key feature of the Monroe Doctrine?

The key feature of the Monroe Doctrine was indeed its opposition to European colonization. Established in 1823 by President James Monroe, this doctrine asserted that the Americas should be free from further European colonization and interference. It aimed to prevent any new European colonial ventures in the Western Hemisphere and symbolized a pivotal moment in American foreign policy, signifying a clear stance against European influence in the region.

By establishing this policy, the United States positioned itself as a protector of newly independent nations in Latin America and signaled that any attempts by European powers to exert control or colonize areas within the Americas would be viewed as acts of aggression against the U.S. This doctrine laid the groundwork for future U.S. engagement in Latin America and served as a foundational principle for asserting American interests in the region.
