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".

 Orwell was a prolific writer on topics related to contemporary English society and literary criticism, whom the British newsweekly "The Economist" in 2008 declared "perhaps the 20th century's best chronicler of English culture."
 His non-fiction cultural and political criticism constitutes the majority of his work, but Orwell also wrote in several genres of fictional literature.
