The Nineteenth Congress of the Communist Party of the Soviet Union was held from 5 to 14 October 1952. It was the first party congress after World War II and the last under Joseph Stalin's leadership. It was attended by many dignitaries from foreign Communist parties, including Liu Shaoqi from China. At this Congress, Stalin gave the last public speech of his life. The 19th Central Committee was elected at the congress.
- The All-Union Communist Party (Bolshevik) was renamed the Communist Party of the Soviet Union.
- Stalin's request to be relieved of his duties in the party secretariat due to his age was rejected by the plenum of the Central Committee held immediately after the congress, as members were unsure about Stalin's intentions.
An unofficial "inner circle" of Stalin's closest associates included Lavrentiy Beria, Nikolai Bulganin, Kliment Voroshilov, Lazar Kaganovich, Georgy Malenkov, Mikhail Pervukhin, Maksim Saburov, and Nikita Khrushchev.
