The "Cheka" was reorganized in 1922 as the State Political Directorate, or GPU, of the NKVD of the RSFSR. In 1922 the USSR formed, with the RSFSR as its largest member. The GPU became the OGPU (Joint State Political Directorate), under the Council of People's Commissars of the USSR. The NKVD of the RSFSR retained control of the "militsiya", and various other responsibilities.
