A story about a revolution amongst the animals of a farm, who chase out the human owners and set up a farm run by the animals themselves. Gradually the pigs take over, and life becomes harder and harder for the rest of the animals, until the climax of the book when they see the pigs and humans talking together, and see no difference between them.
The book was an allegory about the events following the revolution in the Soviet Union, and in particular the rise of Stalinism. Many of the characters in the book are identifiable as historical figures. For instance Daisy, the cart horse relates to Stakanov after whom the Stakanovite movement was named.
Orwell wrote the book following his experiences during the Spanish civil war which are described in another of his books Homage to Catalonia. He intended it to be a strong condemnation of what he saw as the Stalinist corruption of the original socialist ideals that he believed in.
The book was the basis of an animated feature film in 1955.
