OGPU
With the creation of the USSR in December 1922, a unified organization was required to exercise control over state security throughout the new union. Thus, on November 15, 1923, the GPU left the Russian NKVD and was transferred into the all-union Joint State Political Directorate, also translated as "All-Union State Political Administration". Its official name was "Joint State Political Directorate under the Council of People's Commissars of the USSR" (Russian: "Obyedinyonnoye gosudarstvennoye politicheskoye upravleniye" under the SNK of the USSR, Объединённое государственное политическое управление при СНК СССР), or OGPU (ОГПУ).
