The Battle for the Rag is the name given to the LSU–Tulane football rivalry. It is an American college football rivalry game played by the LSU Tigers football team of Louisiana State University and the Tulane Green Wave football team of Tulane University. The game was played nearly every year since its inception in 1893, with the last of ninety-eight games being played in 2009. Tulane and LSU spent much of their athletic histories as members of the same conference: the SIAA from 1899 to 1920, the Southern Conference from 1922 to 1932, and as charter members of the SEC from 1932 to 1966.
