SiPo (Security Police)

In the 1930s, SS chief Heinrich Himmler pursued the consolidation of police and security forces in Nazi Germany under SS control. In 1936, he established the Main Office of the Security Police (SiPo), combining the Kripo (Criminal Police)  and the Gestapo under SS command. The link between the security forces of the German state and the Nazi Party was further strengthened by the appointment of SD chief Reinhard Heydrich Chief of Security Police and SD (Security Service).
