"All animals are equal, but some animals are more equal than others."

"The creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which."

― George Orwell, Animal Farm

Animal Farm is an allegorical novella by George Orwell, first published in England on 17 August 1945. The book tells the story of a group of farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy. Ultimately, however, the rebellion is betrayed, and the farm ends up in a state as bad as it was before, under the dictatorship of a pig named Napoleon.

According to Orwell, the fable 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 had become a brutal dictatorship built upon a cult of personality and enforced by a reign of terror..
