President #5 • Democratic-Republican
James Monroe
1817–1825• 1790s–1820s: The Early Republic
James Monroe was born in Virginia in 1758 and fought in the Revolutionary War before entering politics under the mentorship of Thomas Jefferson and James Madison. He served in the Continental Congress, as a senator, governor of Virginia, diplomat in France and Britain, and secretary of state and war under Madison. His long public career made him a natural successor, and he was elected president in 1816.
Monroe’s first term coincided with what became known as the Era of Good Feelings, a period of reduced national party conflict after the War of 1812. His administration oversaw the acquisition of Florida from Spain through the Adams-Onís Treaty of 1819. That same year, however, the Panic of 1819 exposed weaknesses in the economy and caused widespread hardship.
The Missouri Compromise of 1820 defined the central domestic crisis of his presidency. It admitted Missouri as a slave state and Maine as a free state while attempting to limit slavery’s expansion in parts of the Louisiana Purchase. The compromise temporarily preserved sectional balance but revealed the deepening national conflict over slavery.
Monroe’s most lasting foreign policy act was the Monroe Doctrine of 1823, which warned European powers against new colonization or intervention in the Western Hemisphere. He left office in 1825 and retired with financial difficulties. His presidency is remembered for national consolidation and hemispheric ambition, but also for the expansion of a republic still deeply entangled with slavery and Indigenous dispossession.
