All Animals Are Equal But Some

This is the closing commandment of Animal Farm (1945), Orwell's allegorical novella about the corruptions of revolutionary power. Originally the animals' founding principle was "All animals are equal," but by the novel's end the ruling pigs have secretly amended it to this grotesque revision. Orwell was drawing directly on his experience of Stalinist doublethink during the Spanish Civil War, where he witnessed Communist factions rewrite history and ideology to serve political convenience.
