What did the Monroe Doctrine say?
The Monroe Doctrine had two major points.
1) That the United States would not allow European countries to start new colonies or to interfere with independent countries in the continents of North America or South America.
2) That the United States would not interfere with existing European colonies nor get involved with conflicts between European countries.
Why did President Monroe establish this new doctrine?
Many countries in South America had just gained their independence from European empires such as Spain and Portugal. At the same time, with the defeat of Napoleon in Europe, President Monroe was afraid that European nations would once again try to establish power in the Americas. Monroe wanted to let Europe know that the United States would not allow the European monarchies to regain power in the Americas.
