An American statesman, lawyer, diplomat and Founding Father who served as the 5th president of the United States from 1817 to 1825. A member of the Democratic-Republican Party, Monroe was the last president of the Virginia dynasty and the Republican Generation; his presidency coincided with the Era of Good Feelings, concluding the First Party System era of American politics. He is perhaps best known for issuing the Monroe Doctrine, a policy of opposing European colonialism in the Americas while effectively asserting U.S. dominance, empire, and hegemony in the hemisphere. He also served as governor of Virginia, a member of the United States Senate, U.S. ambassador to France and Britain, the 7th Secretary of State, and the 8th Secretary of War.
