*just now remembering the question, even though it's probably much too late*

Well, George Orwell was closely involved with and deeply affected by the events surround the USSR, such as the British domination and the Russian Revolution. His book Animal Farm is supposed to be a somewhat direct parallel of the Russian Revolution, with Animalism (taught by the wise old pig, Old Major) based off of Communism (taught by Karl Marx), and Napoleon (the corrupt pig leader who twists Old Major's noble beliefs to benefit himself) based off of Joseph Stalin (the leader of the USSR who bastardized Communism). It starts off optimistically with the overthrow of the neglectful farmer, Mr. Jones (Czar Nicholas II) and the foundation of a seemingly perfect society, just like with the Russian Revolution. However, as the pig Napoleon grows more corrupt and the laws of animalism (communism) get twisted, it becomes much less of a utopia and more like an anti-utopia.

1984, on the other hand, basically sticks the reader in the middle of a similar anti-utopia (but a much more depressing one that doesn't have to do with animals sweatdrop ). Like I said, Orwell was deeply affected by the actions of the Soviet Union (look up his biography if you want, I'm too lazy and I haven't committed his life to memory XP ), so he wrote a book embodying all of the hopelessness of soviet society and Stalin's rule, as well as the things he found wrong with it.

So yeah. I hope that helps at least some. ^^; There's tons of similar articles on Google, just look them up if you need more help.
