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.
Nikolay Kruchina
Kruchina joined the party in 1949. In 1962 he became an instructor for the Agricultural Department of the CPSU. In 1963-1965 he was a secretary of the Tselinny Krai Committee of the Communist Party in the Kazakh SSR, in 1965-1978—the First Secretary of the Tselinograd Oblast Committee of the Communist Party in the Kazakh SSR. In 1973 he was awarded Hero of Socialist Labor. In 1971 Kruchina entered the Central Auditing Committee of the CPSU. In 1971 he became a candidate member and in 1976 a full member of the CPSU Central Committee. In 1978-1983 served as a first deputy chairman of the Agricultural Department of the CPSU then headed by Mikhail Gorbachev, became its Chairman after Gorbachev in 1983 and in the same year, after Yury Andropov's assumption of power, finally replaced Georgy Pavlov as the party's administrator of affairs ("upravlyayushchiy delami"). It is known that Kruchina's office transferred millions of dollars as a Soviet help to foreign Communist Parties. For the last time Kruchina visited his office on August 19, the day the abortive Soviet coup attempt of 1991 started. In 1966-1989 he was also a Deputy in the Supreme Council of the Soviet Union and in 1989-1991 People's Deputy of the Soviet Union.
