Animal Farm is set against the backdrop of the Russian Revolution of 1917 and the subsequent establishment of the Soviet Union. The novel allegorically portrays the rise of communism and the corruption of revolutionary ideals. The farm symbolises Russia, with its animals representing different social classes and political figures. The initial rebellion, led by the pigs, reflects the overthrow of the Tsar and the Bolshevik Revolution. Terms like 'Old Major', 'revolution', 'propaganda', and 'corruption' are central themes. Key phrases such as 'All animals are equal, but some animals are more equal than others' encapsulate the betrayal of revolutionary principles. The narrative highlights how revolutionary ideals can be compromised by those in power, leading to tyranny and inequality. The story comments on human nature and political corruption, illustrating that power often corrupts even the most sincere intentions. As the pigs assume leadership, they begin to adopt human traits, symbolising the corrupting influence of power. This context helps readers understand the allegorical nature of the novel and the historical parallels with the Russian Revolution's impact on society.
