The officers (help·info) (contraction of Geheime Staatspolizei: "Secret State Police") was the official secret police of Nazi Germany. Beginning in April 1934, it was under the overall administration of the Schutzstaffel under Heinrich Himmler in his position as leader of the SS and Chief of German Police (Chef der Deutschen Polizei).[2] From September 1939 forward it was administered by the Reichssicherheitshauptamt (RSHA) ("Reich Main Security Office") and was considered a sister organization of the Sicherheitsdienst (SD) ("Security Service") and also a suboffice of the Sicherheitspolizei (SIPO) ("security police").[3]
