The method of control that helped Hitler and the Nazi Party to gain, consolidate, and/or maintain power in Germany was the creation of the SS, the security organization that served as the personal bodyguard of Hitler.
This security group became the closest group to Adolph Hitler and exerted a reign of terror and repression in Germany. Their methods: intimidations, fear, and repression. Historians and experts refer to this as a terror state.
Another important element of this control was Propaganda. Joseph Gobbles was the genius behind the propagandistic program. He was the one that created the messages that made the German people loyal followers of Hitler and the Nazi Party.
