George Orwell's primary reason to write chapter ten of "Animal Farm" is to expose how the pigs have become humanized and have gradually become as oppressive and tyrant as the farmers they took over. While the rest of the animals work hard and have few privileges, the pigs and the dogs have embraced all the power and live comfortable lives. In the end of the story, it is announced that Animal Farm will be called Manor House again, thus emphasizing the pigs' intention to be as totalitarian as the human farmers.
