Of the 139 full members and candidate members elected at the 17th Party Congress, 98 people were killed in the period 1936–1940. Of these 44 (out of 71) were full members, while 55 (out of 68) were candidate members. Of those arrested, over 80 percent of them were below the age of 50. When the 18th Party Congress convened in 1939, 31 individuals remained in the Central Committee. Of these, seven were not reelected, and of them five were pensioned or relieved of leading offices (Grigory Petrovsky, Gleb Krzhizhanovsky, Grigory Broydo, Mikhail Chuvyrin and Isaak Schwartz) while Tikhon Yurkin and Avraami Zavenyagin were reelected to the CC at the 19th Party Congress (in 1952) and the 20th Party Congress (in 1956) respectively. Of the 24 reelected at the 18th Party Congress, four would be subject to violent repression (Mikhail Kaganovich in 1941, Solomon Lozovsky in 1952, Lavrentiy Beria in 1953 and Mir Jafar Baghirov in 1956). Klavdiya Nikolayeva became the only CC member who had previously been active in intra-party opposition to survive the purge.
