The document introduces the characters and setting of George Orwell's novel Animal Farm. Old Major is an old boar who inspires the animals to rebel against their human farmer, Mr. Jones. Snowball and Napoleon emerge as leaders of the rebellion. After the animals drive Mr. Jones off the farm, Napoleon gradually takes control and establishes himself as the undisputed tyrant, rewriting the commandments to assert that some animals are more equal than others. The story is an allegory about the Russian Revolution and rise of Stalinism.
