Thomas Lanier Clingman, known as the "Prince of Politicians," was an American politician who was a Democratic member of the United States House of Representatives from 1843 to 1845 and from 1847 to 1858, and U.S. senator from the state of North Carolina between 1858 and 1861. During the Civil War, he refused to resign his Senate seat and was one of the many southern senators subsequently expelled from the Senate in absentia. He then served as a general in the Confederate States Army.
