General Secretary of the Communist Party of the Soviet Union
In the 1950s, Stalin increasingly withdrew from Secretariat business, leaving the supervision of the body to Georgy Malenkov, possibly to test him as a potential successor. In October 1952, at the 19th Party Congress, Stalin restructured the party's leadership. His request, voiced through Malenkov, to be relieved of his duties in the party secretariat due to his age, was rejected by the party congress, as delegates were unsure about Stalin's intentions. In the end, the congress formally abolished Stalin's office of General Secretary, though Stalin remained one of the party secretaries and maintained ultimate control of the Party. When Stalin died on 5 March 1953, Malenkov was the most important member of the Secretariat, which also included Nikita Khrushchev, among others. Under a short-lived troika of Malenkov, Beria, and Molotov, Malenkov became Chairman of the Council of Ministers but was forced to resign from the Secretariat nine days later on 14 March, leaving Khrushchev in effective control of the body. Khrushchev was elected to the new office of First Secretary at the Central Committee plenum on 14 September of the same year. Originally conceived as a collective leadership, Khrushchev removed his rivals from power in both 1955 and (especially) 1957 and reinforced the supremacy of the First Secretary.
Nikolai Bryukhanov
Bryukhanov was put in charge of the People's Commissariat of Supplies in December 1921. With the creation of the USSR in December 1922, Bryukhanov became the first head of the People's Commissariat of Supplies of the new federation on July 6, 1923. On May 14, 1924, the Commissariat was abolished and Bryukhanov was made deputy People's Commissar of Finance. When the head of the Commissariat, Grigory Sokolnikov, supported Grigory Zinoviev and Lev Kamenev in their unsuccessful opposition to the Soviet leader Joseph Stalin in late 1925, Stalin replaced Sokolnikov with the less influential and apolitical Bryukhanov on January 18, 1926. At the 15th Party Congress in December 1927, Bryukhanov was elected candidate (non-voting) member of the Central Committee of the Soviet Communist Party, a position which he kept until the 17th Party Congress in January 1934.
