Himmler immediately reorganised the police, with the state agencies statutorily divided into two groups: the Ordnungspolizei (Order Police; Orpo), consisting of both the national uniformed police and the municipal police, and the Sicherheitspolizei (Security Police; SiPo), consisting of the Kripo and Gestapo.[5] Reinhard Heydrich was appointed chief of the SiPo and was already head of the party Sicherheitsdienst (Security Service; SD) and the Gestapo.[6][7] The two police branches were commonly known as the Orpo and SiPo (Kripo and Gestapo combined), respectively.[5]
