Animal Farm by George Orwell

The story takes place on a farm somewhere in England. The action of this novel starts when the oldest pig on the farm, Old Major, calls all animals to a secret meeting. He tells them about his dream of a revolution against the Mr. Jones. Three day’s later Major dies, but the speech gives the more intelligent animals a new outlook on life. The pigs, which are considered the most intelligent animals, instruct the other ones. During the period of preparation two pigs can distinguish themselves, Napoleon and Snowball. Napoleon is big, and although he isn't a good speaker, he can assert himself. Snowball is a better speaker, he has a lot of ideas and he is very vivid. Together with another pig called Squealer, who is a very good speaker, they work out the theory of "Animalism". The rebellion start some months later, when Mr. Jones comes home drunk one night, and forgets to feed the animals. They break out of the barns and run to the house, where the food is stored. When Mr. Jones recognizes this he takes out his shotgun, but it is to late for him, all the animals fall over him and drive him off the farm. The animals destroy all whips nose rings, reins, and all other instruments that have been used to suppress them. The same day the animals celebrate their victory with an extra ration of food. The pigs made up the seven commandments, and they write them above the door of the big barn.
1. Whatever goes upon two legs is an enemy.
2. Whatever goes upon four legs, or has wings is a friend.
3. No animal shall wear clothes.
4. No animal shall sleep in a bed.
5. No animal shall drink alcohol.
6. No animal shall kill another animal.
7. All animals are equal.
The animals also agree that no animal shall ever enter the farmhouse, and that no animal shall have contact with humans. These commandments are summarized in the simple phrase: "Four legs well, two legs bad". After some time Jones comes back with some other men from the village to recapture the farm. The animals fight brave, and they manage to defend the farm. Snowball and Boxer receive medals of honor for defending the farm so bravely. Also Napoleon who had not fought at all takes a medal. This is the reason why the two pigs, Snowball and Napoleon, often argue.
