Born in rural Russia in 1902, Suslov became a member of the All-Union Communist Party (Bolsheviks) in 1921 and studied economics for much of the 1920s. He left his job as a teacher in 1931 to pursue politics full-time, becoming one of the many Soviet politicians who took part in the mass repression begun by Joseph Stalin's regime. He was made First Secretary of Stavropol Krai administrative area in 1939. During the war, Suslov headed the local Stavropol guerrilla movement. He became a member of the Organisational Bureau (Orgburo) of the Central Committee in 1946. In June 1950, he was elected to the Presidium of the Supreme Soviet. From 16 October 1952, he was a full member of the 19th Presidium of the CPSU.
