George Orwell's 'Animal Farm' is an allegorical novella that critiques totalitarianism, particularly Stalinism, through a fable about oppressed animals that revolt against their human owner, Mr. Jones. The animals initially seek equality but ultimately succumb to the same oppressive behaviors they sought to escape, reflecting the corrupting influence of power. The themes of the novel remain relevant today, illustrating the cyclical nature of power and the failures of socialism.
