Squealer States that all apples and milk is to be reserved only for the pigs
When Old Major gave his speech he started the idea of animalism. Old Major spoke of a time where animals could be free of labour and man's control and thus started the revolution.
"The Traitors are executed"
Snowball wanted to create a windmill as it would create electricity to light up the Barn House, make farming in general easier and the animals would not have to work as much as they do. But Napoleon didn't like this so he made a whistle like noise and multiple dogs came running and ran at Snowball trying to kill him but Snowball got away and Napoleon took control of the farm.
The inscription "All animals are equal but some animals are more equal than other animals"
When Squealer states that milk and apples are meant only for the pigs because he told all the other animals that science has proven that pigs require milk and apples for their health. This shows that the pigs don't care about the other animals that are actually doing all the work.
When the Animals catch the pigs in the barn house talking to the humans
Napoleon get's his legion of dogs to execute all the animals who have confessed to working with the "Sworn enemy" Snowball.
The animals catch a pig writing on the walls of the barn "All animals are equal but some animals are more equal than other animals"
All animals are equal but some animals are more equal than others
The animals looked into the window and saw the pigs talking, drinking alcohol and playing cards with the neighbouring farm leaders about renaming Animal Farm back to the original name Manor Farm. But by this time the animals couldn't tell the difference between man and pig.
