On 17 June 1936, all police forces throughout Germany were united under the purview of Himmler and the SS.[53] Himmler and Heydrich thus became two of the most powerful men in the country's administration.[60] Police and intelligence forces brought under their administrative control included the SD, Gestapo, Kriminalpolizei (Kripo; criminal investigative police), and Ordnungspolizei (Orpo; regular uniformed police).[61] In his capacity as police chief, Himmler was nominally subordinate to Interior Minister Wilhelm Frick.
