Louis Trezevant Wigfall was an American politician who served as a Confederate States Senator from Texas from 1862 to 1865. He was among a group of leading secessionists known as Fire-Eaters, advocating the preservation and expansion of an aristocratic agricultural society based on slave labor. He briefly served as a Confederate Brigadier General of the Texas Brigade at the outset of the American Civil War before taking his seat in the Confederate Senate. Wigfall's reputation for oratory and hard-drinking, along with a combative nature and high-minded sense of personal honor, made him one of the more imposing political figures of his time. He was also a slave owner.

The Confederate States Congress was both the provisional and permanent legislative assembly of the Confederate States of America that existed from 1861 to 1865. Its actions were, for the most part, concerned with measures to establish a new national government for the Southern proto-state, and to prosecute a war that had to be sustained throughout the existence of the Confederacy. At first, it met as a provisional congress both in Montgomery, Alabama, and Richmond, Virginia. As was the case for the provisional Congress after it moved to Richmond, the permanent Congress met in the existing Virginia State Capitol, a building which it shared with the secessionist Virginia General Assembly.
