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.
Lazar Kaganovich
In 1924, Kaganovich became a member of the Central Committee. From 1925 to 1928, Kaganovich was the First Secretary of the Communist Party of the Ukrainian SSR. He was given the task of "ukrainizatsiya" – meaning at that time the building up of Ukrainian communist popular cadres. He also had the duty of implementing collectivization and the policy of economic suppression of the kulaks (wealthier peasants). He opposed the more moderate policy of Nikolai Bukharin, who argued in favor of the "peaceful integration of kulaks into socialism". In 1928, due to numerous protests against Kaganovich's management, Stalin was forced to transfer Kaganovich from Ukraine to Moscow, where he returned to his position as a Secretary of the Central Committee of the Communist Party, a job he held until 1939. As Secretary, he endorsed Stalin's struggle against the so-called Left and Right Oppositions within the Communist Party, in the hope that Stalin would become the sole leader of the country. In 1933 and 1934, he served as the Chairman of the Commission for the Vetting of the Party Membership ("Tsentralnaya komissiya po proverke partiynykh ryadov") and ensured personally that nobody associated with anti-Stalin opposition would be permitted to remain a Communist Party member. In 1934, at the XVII Congress of the Communist Party, Kaganovich chaired the Counting Committee. He falsified voting for positions in the Central Committee, deleting 290 votes opposing the Stalin candidacy. His actions resulted in Stalin's being re-elected as the General Secretary instead of Sergey Kirov. By the rules, the candidate receiving fewer opposing votes should become the General Secretary. Before Kaganovich's falsification, Stalin received 292 opposing votes and Kirov only three. However, the "official" result (due to the interference of Kaganovich) saw Stalin with just two opposing votes (Radzinsky, 1996).
