Best known as president of the Confederacy during the American Civil War, Jefferson Davis was also a Mexican War hero, served in the House of Representatives and the Senate, and was secretary of war under Franklin Pierce. After the Civil War he became a symbol of the Lost Cause.
The Papers of Jefferson Davis, a documentary editing project based at Rice University in Houston, Texas, has published (1971-2015) a 14 volume edition of his letters and speeches, several of which can be found on this web site. The site also provides extensive information on Davis and his family and numerous images.
