The Declaration of 46

The Declaration of 46 (Russian: Декларация сорока шести, romanized: Deklaratsiya soroka shesti) was a secret letter sent by a group of 46 leading Soviet communists to the Politburo of the Central Committee of the Communist Party of the Soviet Union on 15 October 1923. The declaration followed Leon Trotsky's letter, which was sent to the Politburo on 8 October and expressed similar concerns and thus laying the foundation for the Left Opposition within the Communist Party of the Soviet Union later that year. The vast majority of the signatories were executed during the Great Purge.
