James Monroe, the country's fifth president served two terms as president, with his first term known as the "Era of Good Feelings." He won the election with all but one electoral vote, running on the campaign slogan "Monroe is the man," marking the last time that a U.S. president was elected without any serious competition. Monroe served the country for 50 years in various capacities and held the most positions of any president before or after.
Another thing that distinguishes Monroe among all presidents is that he is the only president who has a foreign capital named after him: Monrovia, Liberia. Founded in 1821, Liberia was a destination for freed former black American slaves. Monroe once traveled to Madrid from Paris via mule, working in the capacity as a Spanish envoy to strike a deal with Spain for the Florida territory. Domestically, he traveled the United States widely and was once the honorary guest at an ox barbecue in South Carolina.
Monroe's farm, Highland, shared a border with Monticello, the estate of Thomas Jefferson. The two were close friends, and Monroe considered Jefferson his mentor. Notably, Monroe died on July 4th, 1831, 5 years to the day that both President John Adams and President Thomas Jefferson died.
