Joseph Stalin, originally Ioseb Besarionis dze Jughashvili, was a Soviet revolutionary, politician and statesman who became the leader of the Soviet Union from 1924 until his death in 1953. He held power as General Secretary of the Communist Party of the Soviet Union (1922–1952) and Chairman of the Council of Ministers of the Soviet Union (1941–1953).
Initially governing the country as part of a collective leadership, he consolidated power to become an informal dictator by the 1930s. Ideologically adhering to the Leninist interpretation of Marxism, he formalised these ideas as Marxism–Leninism, while his own policies are called Stalinism.
Volume 10 of the collected works of Stalin documents the continued fight in the party against the Trotskyite opposition with the majority of this volume focusing on this subject, culminating in the expulsion of Trotsky and his faction from the party.
There isn't too much to say about this volume that can't also be said about volumes 6, 7, 8, and 9 which also deal extensively with the problems of the Trotskyite opposition. However, of special note in this volume is Stalin's work on problems of the Chinese Revolution which refute not only the Trotskyites but also many arguments made by Maoists and Dengists. The article on the International Character of the October Revolution also takes special importance in highlighting the truly internationalist character of the Great October Bolshevik Revolution and its international significance continuing the traditions of the Great French Revolution.
