One of the most celebrated works of modern literature, Animal Farm is George Orwell's satire on the Russian Revolution of 1917 and Stalin's subsequent rule. It tells the story of the animals of Manor Farm, as they rise up against the drunken farmer Mr Jones and the ensuing leadership battle between two pigs, Snowball and Napoleon. They set in motion their 'system of thought', Animalism, a clear play on Communism, with seven tenets including, 'All animals are equal but some animals are more equal than others.'
