Answer: Animal Farm by George Orwell has tons of themes that you can go into depth about. However, probably the most famous would be "The Corruption of Socialist Ideals in the Soviet Union" which is what the book is based on.
Animal Farm is most famous in the West as a stinging critique of the history and rhetoric of the Russian Revolution. Retelling the story of the emergence and development of Soviet communism in the form of an animal fable, 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.
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. Thus, 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.
