The POTUS Timeline
President #5

James Monroe

James Monroe (1758–1831) was the fifth President of the United States, serving from 1817 to 1825. A leading figure of the Democratic-Republican Party, he is best known for the Monroe Doctrine and guiding a period of national unity and westward expansion.

Legacy Summary

Monroe left a lasting mark on U.S. foreign policy: his 1823 Monroe Doctrine warned European powers against new colonial ventures in the Americas and asserted a growing American sphere of influence. He also secured Florida through the Adams–Onís Treaty and settled boundary issues with Britain, reinforcing U.S. territorial claims.

Domestically, Monroe presided over the Era of Good Feelings, a time of relative political harmony after the Federalist decline, but his administration also faced rising sectional tensions over slavery highlighted by the Missouri Compromise. His presidency advanced national infrastructure and westward settlement while leaving complex challenges over union and slavery for future leaders.
