William King Sebastian was an American planter, lawyer, and U.S. senator from Helena, Arkansas. He represented Arkansas as a U.S. Senator, Democrat, from 1848 to 1861. Sebastian withdrew from the Senate at the start of the Civil War and was later formally expelled by the Senate. He took no active part in the Confederate government, and was reinstated by a posthumous resolution in 1877. Sebastian was born in Centerville, Tennessee in 1812; sometime around 1834 he graduated from Columbia College, also in Tennessee, and began studying law. In 1835 he was admitted to the bar and began practice in Helena, Arkansas; later he became a cotton planter. From 1835 to 1837 he was a prosecuting attorney; he served as a circuit court judge from 1840 to 1843, in which year he was made an associate justice of the Arkansas Supreme Court. In 1846 he became a member of the state Senate, serving as its president until 1847. Also in 1846 he served as a presidential elector on the Democratic ticket. In 1848, upon the death of Chester Ashley, he was appointed to the United States Senate, subsequently being elected in his own right. He was reelected in 1853 and 1859. [More at Wikipedia]
