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".
