Answer:
In 1929, Hitler appointed Himmler Reichsführer of the Schutzstaffel (SS.) At the time, the SS served as bodyguards for Hitler and other top Nazi leaders. As the newly appointed leader of the SS, Himmler sought to develop an elite faction of the Nazi Party. In 1929, the SS totaled 280 men. By the time the Nazis came to power in 1933, Himmler had grown the SS to 52,000. Himmler inducted two new functions for the SS—internal security and guardianship over racial purity. In 1931, Himmler established the Sicherheitsdienst (Security Service, or SD) to gather intelligence and monitor opponents within the Nazi Party, leaders of other political parties, and government officials. In 1934, the SD was distinguished as the sole political intelligence agency for Germany. Five years later, in September 1939, Himmler fused the SD with the Reich Security Main Office (RSHA.)
