Sicherheitspolizei

The Sicherheitspolizei (English: Security Police), often abbreviated as SiPo, was a term used in Nazi Germany to describe the state political and criminal investigation security agencies. It was made up by the combined forces of the Gestapo (secret state police) and the Kripo (criminal police) between 1936 and 1939. As a formal agency, the SiPo was folded into the RSHA in 1939, but the term continued to be used informally until the end of the Third Reich.
