Leninism: Introduction to the Study of Leninism
Leninism: Introduction to the Study of Leninism is a 1925 work by Soviet politician Grigory Zinoviev. Leninism would be translated into English by the Communist Party of Great Britain as "Bolshevism or Trotskyism: Where the Line of Trotskyism is Leading" as part of The Errors of Trotskyism in May 1925. The work represents a primary document to the ideological tensions that were building within the Politburo, Central Committee, and the Communist Party of the Soviet Union.
