The 8th Party Congress (8 March 1919 – 23 March 1919) amended the party charter and set up provisions for election of the Politburo, the Orgburo and the Secretariat. The Central Committee plenum elected the new Orgburo of five members and of one candidate member on 25 March 1919. Some key Communist politicians (such as Joseph Stalin, Vyacheslav Molotov, Lazar Kaganovich and others) served as members both of the Orgburo and of the Politburo, but most of the Orgburo members were less important figures than those elected to the Politburo and the Secretariat.
