Thank you Bomba. It has NOTHING to do with animal rights. This book was written way before anyone gave a hoot about farm animal's feelings. Orwell portrayed everyone as animals as a way to hide who he was talking about, and to make things more humorous I think. :D
Each animal symbolizes something.. it is generally thought that Napoleon represents Stalin, ruthless leader of communist Russia. Snowball, the one that got banished is Trotsky. Old Major is a mix of Lenin and the creator of Marxism, Karl Marx, who dreamt of an ideal world that Marxism should provide, though this doesn't ever seem to work out in reality... The scene of the farmer being run out of the farm represents the historical event of the last Czar, Nicholas II, being run out of Russia. Every aspect of the book refers to some aspect of politics, such as Moses the raven, he represents religion, he sticks around when things are good but once the going gets tough just disappears. Each of the battles also represent real events, and when all of the animals start confessing their crimes and getting murdered in front of the crowd actually happened in Russia, to scare people into following Stalin..
The farm Pinchfield represents Nazi Germany, and the farm Foxwood is England and the USA, the capitalists...
Some other good reads include 1984 by George Orwell, which is about a government that takes over every aspect of it's subjects lives, monitoring their every move. It has a pretty tragic end.. Also a Clockwork Orange, probably the most mature novel of the group, would not recommend it to younger peeps, is about a society gone haywire and basically examines whether behavioral modification is an ethical way to deal with crime. My fave of the group as I'm not a huge politics fan. :D
