The struggle for preeminence between Leon Trotsky and Stalin emerges in the rivalry between the pigs Snowball and Napoleon. In both the historical and fictional cases, 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.
