James Monroe (1758s-1831) was the fifth President of the United States (1817-1825). His administration was marked by the acquisition of Florida (1819); the Missouri Compromise (1820), in which Missouri was declared a slave state; and the profession of the Monroe Doctrine (1823), declaring U. S. opposition to European interference in the Americas. The President's parents, father Spence Monroe (ca. 1727-1774), a woodworker and tobacco farmer, and mother Elizabeth Jones Monroe had significant land holdings but little money. Like his parents, he was a slaveholder. Born in Westmoreland County, Virginia, Monroe went to school at Campbelltown Academy and then the College of William and Mary, both in Virginia. After graduating from W&M in 1776, Monroe fought in the Continental Army, serving with distinction at the Battle of Trenton, where he was shot in his left shoulder.
