Rule by Fear
the doctrine of imposing rule on a population, not with direct force, but with the threat of direct force. This doctrine was proposed by Moff Willhuf Tarkin, and also bears the title The Tarkin Doctrine. Emperor Palpatine embraced the theory behind the doctrine, and built his forces accordingly. Huge Star Destroyers, lumbering AT-AT walkers, and even the full body armor of Darth Vader were all parts of the Emperor's implementation.
