Old Major dies, and under the leadership of the pigs, the animals prepare for the Rebellion:
The Rebellion comes much sooner than anyone thought, and the animals break free of Jones's tyranny and drive the humans from the farm.
By the end of chapter two of Animal Farm, the pigs had taught themselves to read and write. The had used an "old spelling book which had belonged to Mr. Jones's children and which had been thrown on the rubbish heap."
After learning to read and write, the pigs had narrowed the principles of Animalism down to seven commandments. They used paint to write the seven commandments on the wall of the big barn. The original commandments were:
- Whatever goes upon two legs is an enemy.
- Whatever goes upon four legs, or has wings, is a friend.
- No animal shall wear clothes.
- No animal shall sleep in a bed.
- No animal shall drink alcohol.
- No animal shall kill any other animal.
- All animals are equal.
The animals began to study the commandments. The clever animals learned them right away. The animals begin to live by the commandments. Since the pigs had learned to read and write first, they contributed their learning to the Rebellion by creating a code for all the animals to honor and obey.
