George Orwell's 1945 allegorical novel "Animal Farm" critiques tyrannical political systems through the story of farm animals who stage a revolution to overthrow their human farmer. The pigs, led by Napoleon, gradually form an authoritarian regime and impose a new tyranny over the other animals, betraying the revolution's founding principle that "All animals are equal." Napoleon represents Stalin and manipulates the animals through propaganda and intimidation, while Boxer symbolizes the exploited proletariat. In the end, the pigs become indistinguishable from humans as inequality replaces the promised equality.
