Animal Farm allegorizes the rise to power of the dictator Joseph Stalin. In the novella, the overthrow of the human oppressor Mr. Jones by a democratic coalition of animals quickly gives way to the consolidation of power among the pigs. Much like the Soviet intelligentsia, the pigs establish themselves as the ruling class in the new society.

The struggle for preeminence between Trotsky and Stalin emerges in the rivalry between the pigs Snowball and Napoleon; the idealistic but politically less powerful figure (Trotsky and Snowball) is expelled from the revolutionary state by the malicious and violent usurper of power (Stalin and Napoleon). The purges and show trials with which Stalin eliminated his enemies and solidified his political base find expression in Animal Farm as the false confessions and executions of animals whom Napoleon distrusts following the collapse of the windmill. Stalin's tyrannical rule and eventual abandonment of the founding principles of the Russian Revolution are represented by the pigs' turn to violent government and the adoption of human traits and behaviors, the trappings of their original oppressors. The novella critiques the violence of the Stalinist regime against the human beings it ruled, and also points to Soviet communism's violence against human logic, language, and ideals.

Animal Farm illustrates how classes that are initially unified in the face of a common enemy, as the animals are against the humans, may become internally divided when that enemy is eliminated. The expulsion of Mr. Jones creates a power vacuum, and it is only so long before the next oppressor assumes totalitarian control. The natural division between intellectual and physical labor quickly comes to express itself as a new set of class divisions, with the "brainworkers" (as the pigs claim to be) using their superior intelligence to manipulate society to their own benefit.

 

One of the novel's most impressive accomplishments is its portrayal not just of the figures in power but also of the oppressed people themselves. Animal Farm is not told from the perspective of any particular character, though occasionally it does slip into Clover's consciousness. Rather, the story is told from the perspective of the common animals as a whole. Gullible, loyal, and hardworking, these animals give Orwell a chance to sketch how situations of oppression arise not only from the motives and tactics of the oppressors but also from the naïveté of the oppressed, who are not necessarily in a position to be better educated or informed. When presented with a dilemma, Boxer prefers not to puzzle out the implications of various possible actions but instead to repeat to himself, "Napoleon is always right." Animal Farm demonstrates how the inability or unwillingness to question authority condemns the working class to suffer the full extent of the ruling class's oppression.

In Animal Farm, the pigs gradually twist and distort a rhetoric of socialist revolution to justify their behavior and to keep the other animals in the dark. The animals heartily embrace Old Major's visionary ideal of socialism, but after Old Major dies, the pigs gradually twist the meaning of his words. As a result, the other animals seem unable to oppose the pigs without also opposing the ideals of the Rebellion. By the end of the novella, after Squealer's repeated reconfigurations of the Seven Commandments in order to decriminalize the pigs' treacheries, the main principle of the farm can be openly stated as "ALL ANIMALS ARE EQUAL, BUT SOME ANIMALS ARE MORE EQUAL THAN OTHERS." This outrageous abuse of the word "equal" and of the ideal of equality in general typifies the pigs' method, which becomes increasingly audacious as the novel progresses. Orwell's sophisticated exposure of this abuse of language remains one of the most compelling and enduring features of Animal Farm, worthy of close study even after we have decoded its allegorical characters and events.
