Old major(the gray pig) tells the animals of his dream. His dream was about animalism. The idea that all animals are equal. He also teaches them the song "Beasts of England" and how the animals will rel the humans. He dies 3 days after this.
The animals end up running out the farm owners Mr and Mrs Jones. Then pigs are taking control of the farm. They are the smartest animals in the farm. They make commandments that they follow. Some of them are all animals are equal and no animal shall sleep in a bed.
Keep working comrades I need extra rations.
One of the pigs named Napoleon gets the dogs to chase off another pig named snowball. He starts to talk bad about him and the animals start to believe him.
Napoleon gets paranoid of the animals rebelling. There was a storm one day and the windmill that they worked on for months was broken. He blamed it on Napoleon and the animals began to believe him. He also gets a little bit crazy with the amount of power he has.
Snow ball did this comrades.
The animals are getting overworked, their rations are getting reduced, and Napoleon is getting special treatment.
The pigs start to associate with humans and act like humans. They also change the commandments to be able to get even more special treatment.
