In conclusion...
As you have read, the comparisons between real-life totalitarian states and the fictional, manufactured state of George Orwell's Animal Farm are strikingly similar. Orwell perfectly captured the true essence of the totalitarian state. Animal Farm so closely resembles the dictatorship of totalitarian states such as Stalinist Russia, Fascist Italy, and Nazi Germany and the main characters of each like Joseph Stalin, Benito Mussolini, and Adolf Hitler. Orwell compared not only the people, but also the events, especially how they gained and maintained power or their respective nations. The novel parallels these totalitarian states to a tee, showing exactly how the totalitarian rules accrued power over time, committing numerous atrocities to their own people, all while feeding them with propaganda to make the people believe that a Joseph Stalin or an Adolf Hitler were actually heroes or saviors. Just by reading Animal Farm, one is able to understand the true meaning of a totalitarian state without studying any real-life ones, and once one studies both it is impossible to not see the similarities. Whether it be Napoleon and the pigs or Mussolini and the Black-shirts, each totalitarian party ruled in the same way: benefit themselves, lie to their subjects, and gather and retain as much power as they could. This is what the true totalitarian state means, at its purest form, its core.
