"The SS came into being in early 1925, by Hitler's order, as a select corps drawn from SA membership to serve as an efficient, elite, and completely dependable bodyguard for the party's leadership. The emphasis from the start was on loyalty, obedience, and discipline, but the SS remained insignificant in size and undistinguished in function until Hitler appointed Heinrich Himmler to head it and conferred upon him, in January 1929, the grandiose title of Reichsführer-SS. Himmler soon transformed the SS into an organized guided solely by the will of the Führer and that became, in Hans Buchheim's words, "the real and essential instrument of the Führer's authority." Indeed, Himmler came to regard himself as an instrument of Hitler's will."
