Old Major calls the midnight meeting, describes the animals' suffering, articulates the principles of Animalism, and teaches 'Beasts of England.'

Old Major dies, Animalism is developed by the pigs, the Rebellion happens ahead of schedule, and the Seven Commandments are painted on the barn.

The first harvest under animal management, the reading and writing campaign, the pigs' assumption of privilege, and Napoleon taking the puppies.

Animal Farm's Rebellion spreads to neighbouring farms, Mr. Jones attempts to retake the farm, and Snowball leads the defence at the Battle of the Cowshed.

Mollie defects, the windmill debate divides the farm, and Napoleon expels Snowball using the trained dogs.

The animals work sixty-hour weeks on the windmill, Napoleon begins trading with humans, the pigs move into the farmhouse, and the windmill collapses in a storm.

Winter hardship, the hens' rebellion, the show trial executions, Clover's grief, and the abolition of 'Beasts of England.'

Napoleon's cult of personality, the timber negotiations, Frederick's forgeries, the destruction and loss of the windmill, and the discovery of alcohol.

Boxer's injury and collapse, his removal to the knacker, Squealer's false account of his death, and the pigs' banquet.

Years pass, the pigs walk on two legs, the last commandment is revealed, the human farmers are entertained, and the animals cannot tell pig from man.
