The Joint State Political Directorate (JSPD) (OGPU; Объединённое государственное политическое управление) was the intelligence and state security service and secret police of the Soviet Union from 1923 to 1934. The OGPU was formed from the State Political Directorate of the Russian Soviet Federative Socialist Republic one year after the founding of the Soviet Union and responsible to the Council of People's Commissars. The agency operated inside and outside the Soviet Union, persecuting political criminals and opponents of the Bolsheviks such as White émigrés, Soviet dissidents, and anti-communists. The OGPU was based in the Lubyanka Building in Moscow and headed by Felix Dzerzhinsky until his death in 1926, and then by Vyacheslav Menzhinsky, until it was reincorporated as the Main Directorate of State Security (GUGB) of the NKVD in 1934. Following the formation of the Soviet Union in December 1922, the ruling Russian Communist Party (Bolsheviks) saw the need for a unified intelligence service to exercise control over state security throughout the new union. At the time, the State Political Directorate (GPU) served as the secret police for the Russian Soviet Federative Socialist Republic (RSFSR) and was successor to the Cheka. It was responsible to the Council of People's Commissars, which functioned as the highest executive body of the Soviet Union after the formation. On 15 November 1923, the GPU was dissolved and reformed into the Joint State Political Directorate (OGPU) with its jurisdiction covering the entirety of the Soviet Union. Its official full name was the Joint State Political Directorate under the Council of People's Commissars of the USSR (Объединённое государственное политическое управление при СНК СССР, Obyedinyonnoye gosudarstvennoye politicheskoye upravleniye pri SNK SSSR), though the name is also translated as the All-Union State Political Administration and Unified State Political Directorate. Felix Dzerzhinsky, the chairman of the State Political Directorate and the Cheka, was appointed as the OGPU's first chief.
