History of South America

What gave the US some control in affairs?

The Monroe Doctrine gave the US some control in affairs. It was a policy that was proclaimed by US President James Monroe on December 2, 1823. The doctrine declared that the American continents were no longer open to colonization by European powers and that any further attempts by European nations to colonize or interfere with the affairs of the Americas would be viewed as an act of aggression against the United States. The doctrine was a major turning point in US foreign policy, as it marked the first time that the US had asserted its influence in international affairs. The Monroe Doctrine was influential in shaping the course of US foreign policy in the 19th and 20th centuries, and it remains an important part of US foreign policy today.
