James Monroe was an American statesman, lawyer, diplomat and Founding Father who served as the fifth 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 the American politics. He is perhaps best known for issuing the Monroe Doctrine, a policy of opposing European colonialism in the Americas. He also served as the governor of Virginia, a member of the United States Senate, the U.S. ambassador to France and Britain, the seventh Secretary of State, and the eighth Secretary of War.
Born into a planter family in Westmoreland County, Virginia, Monroe served in the Continental Army during the American Revolutionary War. After studying law under Thomas Jefferson from 1780 to 1783, he served as a delegate in the Continental Congress. As a delegate to the Virginia Ratifying Convention, Monroe opposed the ratification of the United States Constitution. In 1790, he won election to the Senate, where he became a leader of the Democratic-Republican Party.
