On Manor Farm Old Major calls the animals for a meeting in the farm to tell them the dream he had the night before. The dream was about the animals revolting against Mr.Jones and the humans. When he dies due to their intelligent species, the pigs and create a new government for all the animals in the farm
The animals made new rules for the animals in the farm call ed the 7 Commandments of Animalism . The pigs abuse their power and start to manipulate the animals and breaking the rules for themselves. They then become leaders of the farm but shortly after that Napolean has his army chase Snowball off of the farm that way he could become the leader by himself.
Now that Napolean is supreme leader he appoints only pigs to make decisions and help rule the farm. Realizing he's abusing his power he starts to feel threatened that someone is going to overthrow him.
Napolean then uses Snowball as his scapegoat and blames all the conflict and issues taking place on the farm on Snowball instead of taking responsibility for them. He then has his dogs run Snowball off the farm because he knew Snowball could've been a better leader than him and taken Napoleon's spot
Now that the pigs have been changing the commandments and slowly becoming more unfair the other animals on the farm start to notice. The animals on the farm are not doing too well because they're working too much on the farm. As the pigs rise the other animals start to fall and notice how they are not being treated the same and he pigs are living a more luxurious life.
The pigs on the farm are becoming more and more like humans due to separating themselves from the rest of the animals and giving themselves more privileges than the other animals. All of the other animals on the farm fully recognize that the pigs are higher above them and the rest of the animals are not treated them same.
