In 1922, at the end of the Civil War, the Cheka was dissolved and reorganized as the State Political Directorate (Gosudarstvennoe Politicheskoe Upravlenie, or GPU), a section of the NKVD. With the formation of the Soviet Union later that year, the GPU was again reorganized as the Joint State Political Directorate (Obyedinyonnoye gosudarstvennoye politicheskoye upravleniye, or OGPU), directly under the Council of People's Commissars. These changes did not diminish Dzerzhinsky's power; he was Minister of the Interior, director of the Cheka/GPU/OGPU, Minister for Communications, and director of the Vesenkha (Supreme Council of National Economy) 1921–24. Indeed, while the (O)GPU was theoretically supposed to act with more restraint than the Cheka, in time its "de facto" powers grew even greater than those of the Cheka.
