In September 1939, the Reichssicherheitshauptamt or Reich Main Security Office (RSHA) was created as the command organization for the various state investigation and security agencies.[6] The Hauptamt Sicherheitspolizei was officially abolished and its departments were folded into the RSHA. The Gestapo became Amt IV (Department IV) and the Reichskriminalpolizeiamt became Amt V (Department V), the Kriminalpolizei in the RSHA.[6]
