The Gestapo was the official secret police of Nazi Germany, whereas the Schutzstaffel, or SS, was the main paramilitary organization of the Nazi regime. The Gestapo played an important role in controlling the German citizens, while the SS controlled the police and was responsible for the administration of the Nazi concentration camp system.
Hermann Goring founded the Gestapo in 1933. In 1934, the organization fell into the administration of Heinrich Himmler, the SS national leader. The Gestapo had a significant network of informers who terrorized the population. By the end of the Second World War, the SS became the most powerful organization of the Nazi regime. After 1945, it was banned in Germany together with the Nazi Party.
