When Yakov Sverdlov died on 19 March 1919, the party lost its leading organiser. At the 8th Party Congress (18–23 March 1919) the Central Committee was instructed to establish the Political Bureau (Politburo), the Organisational Bureau (Orgburo) and the Secretariat, which was to consist of one Responsible Secretary (later renamed to General Secretary). Originally, the Politburo was composed of 5 (full) members; its first members were Vladimir Lenin, Leon Trotsky, Joseph Stalin, Lev Kamenev and Nikolay Krestinsky. There were three other (candidate) members; these were Nikolai Bukharin, Mikhail Kalinin and Grigory Zinoviev. At the beginning, the Politburo was charged with solving immediate problems – it became the top-policy organ. Certain delegates of the 8th Party Congress raised objections to the establishment of the Politburo, claiming that its establishment would turn Central Committee members into second-class officials. In response, the Politburo was ordered to deliver reports to the Central Committee, and Central Committee members were given the right to attend Politburo sessions. At the sessions, Central Committee members could participate with a consultative voice, but could not vote on matters.
