Central Executive Committee of the Soviet Union

The Central Executive Committee of the USSR (Russian: Центральный исполнительный комитет СССР, romanized: Tsentralʹnyĭ ispolnitelʹnyĭ komitet SSSR), which may be abbreviated as the CEC (Russian: ЦИК, romanized: TsIK), was the supreme governing body of the USSR in between sessions of the All-Union Congress of Soviets from 1922 to 1938. The Central Executive Committee elected the Presidium, which, like its parent body, was delegated governing authority when the other was not in session. The chairman of the Presidium, served as the ceremonial head of state of the USSR. The Central Executive Committee also elected the Council of People's Commissars which was its executive and administrative organ. The Central Executive Committee of the USSR was established in 1922 by the First All-Union Congress of Soviets, and was replaced by the Presidium of the Supreme Soviet in 1938.

Initially the committee had four co-chairs, after 1925 there were seven. The Kazakh and Kirghiz SSRs were created in 1936 and did not have co-chairs in the committee, as it dissolved just two years later.
