Old Major has passed. This is tough news to tell to you all.
The animals then believe they should revolt against Jones!! Old Major represents Lenin and this gives Snowball (Trotsky) and Napoleon (Stalin) to start running for leader.
Mr Jones was overthrown by the animals. It's time for the animals to take charge. Manor Farm no longer, it's Animal Farm!
Snowball and Napoleon called for a meeting, in which they wrote down the ruled of the renamed, Animal Farm. These rules include everything an animal should follow and Snowball starts teaching them to read, write and talk.
Snowball presents his plans for the windmill. Napoleon is not happy about this and calls for his dogs to chase Snowball off of Animal farm. He was then not allowed back to the farm and was sent into exile, like Trotsky. He was not later killed but probably died.
The other farmers, who owned farms nearby, saw the windmill and started to revolt and attempeted to take Animal Farm for themselves. While they did this, Jones blows up the windmill, with himself inside of it resulting in his death. In the fight, boxer got shot in the leg. This caused him to be unable to work and Napoleon therefore sent him awayh to be killed and used.
Finally, the windmill was complete but the pigs were caught drinking, walking on two legs, wearing human clothes and sleeping in beds. This goes against all of the rules they had made for the farm which was then changedin favor of the pigs to make them more equal than the other animals.
