Organization of the Communist Party of the Soviet Union

The organization of the Communist Party of the Soviet Union was based on the principles of democratic centralism. The governing body of the Communist Party of the Soviet Union (CPSU) was the Party Congress, which initially met annually but whose meetings became less frequent, particularly under Joseph Stalin (dominant from the late 1920s to 1953). Party Congresses would elect a Central Committee which, in turn, would elect a Politburo and a Secretariat. Under Stalin, the most powerful position in the party became the General Secretary, who was elected by the Politburo and Secretariat. In 1952 the Politburo became the Presidium. In theory, supreme power in the party was invested in the Party Congress. However, in practice the power structure became reversed and, particularly after the death of Lenin in January 1924, supreme power became the domain of the General Secretary. In the late Soviet Union the CPSU incorporated the communist parties of the 15 constituent republics (the communist branch of the Russian SFSR was established in 1990). Before 1990 the communist party organization in Russian oblasts, autonomous republics and some other major administrative units were subordinated directly to the CPSU Central Committee. At lower levels, the organizational hierarchy was managed by Party Committees, or partkoms (партком). A partkom was headed by the elected "partkom bureau secretary" ("partkom secretary", секретарь парткома). At enterprises, institutions, kolkhozes, etc., they were called as such, i.e., "partkoms". At higher levels the Committees were abbreviated accordingly: obkoms (обком) at oblast (zone) levels (known earlier as gubkoms (губком) for guberniyas), raikoms (райком) at raion (district) levels (known earlier as ukoms (уком) for uyezds), gorkom (горком) at city levels, etc. The same terminology ("raikom", etc.) was used in the organizational structure of Komsomol. The bottom level of the Party was the primary party organization (первичная партийная организация) or party cell (партийная ячейка).
