Personally, if I didn't know who everyone was, I probably would have thought it was a very boring book. however, knowing the history helps so much. Study the events that lead up to WWII, along with WWII itself.
It's Russia, not Germany - take a look at the events:
The October Revolution: The old farmer is driven off.
The proclamation of Equality of all animals and the liberation of the suppressed working classes: The animals celebrating their freedom.
The banishment of one of the ruling pigs: The conflict between Trotzki and Stalin.
The animals are labouring just as hard as before, and instead of the farmer, the swine are now occupying the house and force all others to sustain their wealth: Just a single look at the former soviet union with its corrupt leadership suffices to see the parallels.
That has always been the problem of violent revolutions: After the old regime is gone, others will occupy the positions of power, and be corrupted by it in no time. In order to change the structures of power, you need to change them from the inside, and not by force. Otherwise, you just chop off the hydra's heads to have them growing back more hideous than before. That's why you might call the supposed communism of the East "red fascism". The working classes have never been free. In place of the Czar, they now had Josef Stalin, who sent millions of innocent people to death camps to satisfy his deeply seated, paranoid fear of his own people.
