The Great Territorial War was a conflict that took place between the Galactic Republic and the Third Sith Empire. The war was set some time between the Mandalorian Wars and the New Sith Wars. By the time of the Invasion of Utapau, school children would play war games with their friends and re-enact the Great Territorial War. Holo-dramas were made about the war depicting supposedly honorable Republic soldiers rushing into combat to defeat the so-called evil Sith in order to defend freedom and liberty.
