"Animal Farm, known at the beginning and the end of the novel as the Manor Farm, symbolizes Russia and the Soviet Union under Communist Party rule. But more generally, Animal Farm stands for any human society, be it capitalist, socialist, fascist, or communist. It possesses the internal structure of a nation, with a government (the pigs), a police force or army (the dogs), a working class (the other animals), and state holidays and rituals. Its location amid a number of hostile neighboring farms supports its symbolism as a political entity with diplomatic concerns."
