The working class animals were losing all of their rights promised to them by Napoleons. But Napoleon's friend Squealer justifies everything that Napoleon does and insists that he is making life better for everyone, even though the common animals are cold and hungry.
Mr. Frederick, a neighboring farmer, cheats Napoleon in a trade and attacks the farm with dynamite. He destroys the windmill that the animals built. They battle the farmer and Boxer the horse gets wounded. Boxer's injuries greatly weaken him. When the animals are rebuilding the windmill, Boxer is very weak and collapses. The next day Boxer can't be found. Napoleon sold him to a glue factory to get money for whiskey. The other animals don't know about this. .
After many years on animal farm the pigs start to walk and act like humans, they also start to wear clothes. The seven principles of animalism inscribed on the side of the barn are compacted into only one, which states, "All animals are equal, but some are more equal than others." This law demonstrates how power corrupts. The pigs thought that they were better than all of the other animals, or the working class. Napoleon formed an ally with human farmers against the working class of both animal and human communities. He changes the name of the farm back to the Manor farm. This last act of Napoleon is his final step to abandoning the principles of animalism that were Majors dreams.
Napoleon was the pig that was the leader of animal farm after the rebellion against Mr. Jones. He was power hungry. Snowball was the pig that challenged Napoleon for leadership and was forced off the farm. He was true to the original Animalist dream. Boxer was a carthorse that was very strong. He did most of the work on the farm. He wasn't that smart but he was very loyal to Napoleon. Squealer was the pig that spread propaganda for Napoleon. Major was a prize winning boar who was the inspiration for the rebellion.
