After the death of old Major, the animals spend their days secretly planning the rebellion, although they are unsure when it will occur. Because of their intelligence, the pigs are placed in charge of educating the animals about Animalism, the name they give to the philosophy expounded by Major in Chapter 1. Among the pigs, Snowball and Napoleon are the most important to the revolution. Despite Mollie's concern with ribbons and Moses' tales of a place called Sugarcandy Mountain, the pigs are successful in conveying the principles of Animalism to the others.
The rebellion occurs when Jones again falls into a drunken sleep and neglects to feed the animals, who break into the store-shed in search of a meal. When Jones and his men arrive, they begin whipping the animals but soon find themselves being attacked and chased off the farm. The triumphant animals then destroy all traces of Jones, eat heartily, and revel in their newfound freedom. After a tour of Jones' house, they decide to leave it untouched as a museum. Snowball changes the sign reading "Manor Farm" to "Animal Farm" and paints the Seven Commandments of Animalism on the wall of the barn. The cows then give five buckets of milk, which Napoleon steals.
