George Orwell's 1945 novel 'Animal Farm' is an example of dystopian literature. It tells the story of farm animals who overthrow their human owner and set up a society governed on the principle that "All animals are equal." However, the pigs gradually take power and exploit the other animals, using propaganda and fear to control them. The book serves as a warning about totalitarianism and the corruption of power. As the pigs become indistinguishable from humans, 'Animal Farm' highlights how even well-intentioned revolutions can go wrong when individual freedoms are lost.
