15th Congress of the All-Union Communist Party (Bolsheviks)
In October 1927, the last Left Opposition members were expelled from the Central Committee elected by the 14th Congress, and in November 1927 Leon Trotsky and Grigory Zinoviev were expelled from the Party itself.
Repudiation of the United Opposition
The 15th Congress of the All-Union Communist Party (Bolsheviks) was convened in Moscow on December 2, 1927. This marked the first Soviet Communist Party Congress in two years, this despite the fact that party regulations called for annual meetings. The gathering was retrospectively remembered as the "Congress of the Collectivization of Agriculture and of the Socialist Offensive on All Fronts" in the celebratory official party history of 1962, although in actual fact a major part of time spent by the gathering related to internal party politics and the final ritualistic repudiation of the United Opposition of Trotsky, Zinoviev, and their supporters, effectively ending a two-year factional war.
Oppositionists Christian Rakovsky and Lev Kamenev held brief speeches in front of the Congress. Rakovsky's speech was interrupted fifty-seven times by his opponents, including Nikolai Bukharin, Martemyan Ryutin, and Lazar Kaganovich. Although, unlike Rakovsky, Kamenev used the occasion to appeal for reconciliation, he was nevertheless interrupted twenty-four times by the same group.
Theses on Industrialization
The Central Committee adopted a set of theses regarding industrialization which had been prepared in October 1927 by the Central Committee.
Election of a new Central Committee
The 15th Congress elected a new Central Committee to govern activities of the Communist Party during the period in between Congresses.
