Animal Farm (1945) - satirical allegory of the Russian Revolution, particularly directed against Stalin's Russia.

Led by the pigs, the Animals on Mr Jones's farm revolt against their human masters. After their victory they decide to run the farm themselves on egalitarian principles. Inspired by the example of Boxer, the hard-working horse, the cooperation prosper. The pigs become corrupted by power and a new tyranny is established under Napoleon (Stalin). 'All animals are equal, but some animals are more equal than others.'

Snowball (Trotsky), an idealist, is driven out.
