ソ連共産党政治局
As head of the Politburo of the Communist Party of the Soviet Union, Stalin consolidated near-absolute power in the 1930s with a Great Purge of the party that claimed to expel "opportunists" and "counter-revolutionary infiltrators." Those targeted by the purge were often expelled from the party, though more severe measures ranged from banishment to the Gulag labor camps to execution after trials held by NKVD troikas.
