James Monroe was president of the United States from 1817-1825 and is best known for establishing the aggressive foreign policy stand known as the Monroe Doctrine. James Monroe served one term as governor of Virginia, then was sent to France by Thomas Jefferson
to negotiate the Louisiana Purchase. An officer during the American Revolution, Monroe was an all-around statesman whose career included stints as congressman, senator, foreign diplomat and cabinet member. In 1811 he was appointed Secretary of State under President James Madison
, and in 1816 Monroe won the presidential election. He was easily re-elected in 1820 (winning 231 of 232 electoral votes), and his administration was termed "The Era of Good Feelings", a time when the United States focused on expansion and ignored the troubles of the European nations. He is famous for the Monroe Doctrine (1823), which proclaimed U.S. hostility toward any European intervention in the Americas.
