In George Orwell's novel "Animal Farm," the animals establish an initially egalitarian society known as Animalism, where all animals are equal and participate in the decision-making process. However, over time, the pigs, led by Napoleon, seize power and establish a totalitarian regime, turning Animal Farm into a dictatorship. This transition reflects the allegorical critique of the Soviet Union and the rise of Joseph Stalin, highlighting the corruption and abuse of power that can occur within revolutionary movements.
