full_context: Document 1: Animal Farm (1954 film): Animal Farm is a 1954 British-American adult animated comedy-drama film by Halas and Batchelor, based on the book "Animal Farm" by George Orwell. It was the first British animated feature to be released ("Water for Firefighting" and "Handling Ships", two feature length wartime training films, were produced earlier, but did not receive a formal cinema release). The US CIA paid for the filming, part of the American cultural offensive during the Cold War, and influenced how Orwell's ideas were to be presented.

Document 3: Animal Farm: Animal Farm is an allegorical novella by George Orwell, first published in England on 17 August 1945. According to Orwell, the book reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union. Orwell, a democratic socialist, was a critic of Joseph Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the Spanish Civil War. The Soviet Union, he believed, had become a brutal dictatorship, built upon a cult of personality and enforced by a reign of terror. In a letter to Yvonne Davet, Orwell described "Animal Farm" as a satirical tale against Stalin (""un conte satirique contre Staline""), and in his essay "Why I Write" (1946), wrote that "Animal Farm" was the first book in which he tried, with full consciousness of what he was doing, "to fuse political purpose and artistic purpose into one whole".
Document 4: Joseph Stalin: Joseph Vissarionovich Stalin (18 December 1878 – 5 March 1953) was a Georgian-born Soviet revolutionary and political leader.

Ideologically a Marxist and a Leninist, Stalin helped to formalise these ideas as Marxism–Leninism while his own policies became known as Stalinism.
