Nineteen Eighty-Four uses themes from life in the Soviet Union and wartime life in Great Britain as sources for many of its motifs.
The statement "2 + 2 = 5", used to torment Winston Smith during his interrogation, was a Communist party slogan from the second five-year plan, which encouraged fulfillment of the five-year plan in four years. The slogan was seen in electric lights on Moscow house-fronts, billboards and elsewhere.
The switch of Oceania's allegiance from Eastasia to Eurasia is evocative of the Soviet Union's changing relations with Nazi Germany, who were open adversaries until the signing of the Treaty of Non-Aggression. Thereafter, and continuing until the Nazi invasion of the Soviet Union, no criticism of Germany was allowed in the Soviet press, and all references to prior party lines stopped.
The description of Emmanuel Goldstein, with a "small, goatee beard", evokes the image of Leon Trotsky. The film of Goldstein during the Two Minutes Hate is described as showing him being transformed into a bleating sheep. This image was used in a propaganda film during the Kino-eye period of Soviet film, which showed Trotsky transforming into a goat. Goldstein's book is similar to Trotsky's highly critical analysis of the USSR, The Revolution Betrayed, published in 1936.
The omnipresent images of Big Brother, a man described as having a moustache, bears resemblance to the cult of personality built up around Joseph Stalin.
The news in Oceania emphasised production figures, just as it did in the Soviet Union, where record-setting in factories (by "Heroes of Socialist Labor") was especially glorified. The best known of these was Alexey Stakhanov, who purportedly set a record for coal mining in 1935.
The tortures of the Ministry of Love evoke the procedures used by the NKVD in their interrogations, including the use of rubber truncheons, being forbidden to put your hands in your pockets, remaining in brightly lit rooms for days, and the victim being shown a mirror after their physical collapse.
The random bombing of Airstrip One is based on the Buzz bombs, which struck England at random in 1944–1945.
The Thought Police is based on the NKVD, which arrested people for random "anti-soviet" remarks. The Thought Crime motif is drawn from Kempeitai, the Japanese wartime secret police, who arrested people for "unpatriotic" thoughts.
The confessions of the "Thought Criminals" Rutherford, Aaronson and Jones are based on the show trials of the 1930s, which included fabricated confessions by prominent Bolsheviks Nikolai Bukharin, Grigory Zinoviev and Lev Kamenev to the effect that they were being paid by the Nazi government to undermine the Soviet regime under Leon Trotsky's direction.
In 1940 Argentine writer Jorge Luis Borges published Tlön, Uqbar, Orbis Tertius which described the invention by a "benevolent secret society" of a world that would seek to remake human language and reality along human-invented lines. The story concludes with an appendix describing the success of the project. Borges' story addresses similar themes of epistemology, language and history to 1984.
The song "Under the Spreading Chestnut Tree" ("Under the spreading chestnut tree, I sold you, and you sold me") was based on an old English song called "Go no more a-rushing" ("Under the spreading chestnut tree, Where I knelt upon my knee, We were as happy as could be, 'Neath the spreading chestnut tree."). The song was published as early as 1891. The song was a popular camp song in the 1920s, sung with corresponding movements (like touching your chest when you sing "chest", and touching your head when you sing "nut"). Glenn Miller recorded the song in 1939.
The "Hates" (Two Minutes Hate and Hate Week) were inspired by the constant rallies sponsored by party organs throughout the Stalinist period. These were often short pep-talks given to workers before their shifts began (Two Minutes Hate), but could also last for days, as in the annual celebrations of the anniversary of the October revolution (Hate Week).
Orwell fictionalized "newspeak," "doublethink," and "Ministry of Truth" as evinced by both the Soviet press and that of Nazi Germany. In particular, he adapted Soviet ideological discourse constructed to ensure that public statements could not be questioned.
Winston Smith's job, "revising history" (and the "unperson" motif) are based on the Stalinist habit of airbrushing images of 'fallen' people from group photographs and removing references to them in books and newspapers. In one well-known example, the Soviet encyclopaedia had an article about Lavrentiy Beria. When he fell in 1953, and was subsequently executed, institutes that had the encyclopaedia were sent an article about the Bering Strait, with instructions to paste it over the article about Beria.
Big Brother's "Orders of the Day" were inspired by Stalin's regular wartime orders, called by the same name. A small collection of the more political of these have been published (together with his wartime speeches) in English as "On the Great Patriotic War of the Soviet Union" By Joseph Stalin. Like Big Brother's Orders of the day, Stalin's frequently lauded heroic individuals, like Comrade Ogilvy, the fictitious hero Winston Smith invented to 'rectify' (fabricate) a Big Brother Order of the day.
The Ingsoc slogan "Our new, happy life", repeated from telescreens, evokes Stalin's 1935 statement, which became a CPSU slogan, "Life has become better, Comrades; life has become more cheerful".
