## Step 1<br />The Monroe Doctrine was a significant moment in the foreign policy of the United States. It was articulated by President James Monroe in his seventh annual message to Congress on December 2, 1823. The doctrine had a profound impact on the foreign policy of the United States for many years.<br /><br />## Step 2<br />The doctrine stated that further efforts by European nations to colonize land or interfere with states in the Americas would be viewed as acts of aggression requiring U.S. intervention. This doctrine was a clear indication of the United States' readiness to resist any interference in the Western Hemisphere by outside powers.<br /><br />## Step 3<br />The doctrine did not express a desire for the United States to expand its boundaries to the Pacific Ocean, nor did it express a readiness to act aggressively to preserve peace in Europe and around the world. It also did not express a preference for the United States to restrict its political and trade relationships to its nearest neighbors.
