Animal farm: a fairy story. George Orwell. 1989.

Animal Farm tells the story of how a group of animals on a farm overthrow the farmer who puts them to work, and set up an equal society where all animals work and share the fruits of their labour. As time goes on, it becomes clear that the society the animals have constructed is not equal at all. It’s well-known that the story is an allegory for Communist Russia under Josef Stalin, who was leader of the Soviet Union when Orwell wrote the book.
