The Tarkin Doctrine
Imperial Communique 001044.92v. This means very little to most people in that name. Better known as the Tarkin Doctrine, it made the Empire much more fearsome and powerful. Sent by Governor Tarkin of the Seswenna System, it outlined creating oversectors, where rebellions were possible and supply extra troops there, giving command of this oversector to one person who reports directly to the Emperor, using HoloNet only for the Imperial Navy, for better communications between fleets, rule through fear, then force, and the creation of what would later become the Death Star. As you may know, all of these greatly changed the way the Empire operated.
