Snowball believes in a continued revolution: he argues that to defend Animal Farm, he must strengthen the reality of
Old Major's dream of a life without humans and that they must stir up rebellions in other farms throughout England. However,
Napoleon always disagrees with any ideas that Snowball has because he does not want Snowball to lead Animal Farm, wanting to lead it himself with an iron fist. Snowball writes the
Seven Commandments for Animal Farm, which are later altered by
Squealer under the orders of Napoleon, to accommodate the actions of the pigs; the commandment stating "No animal shall drink
alcohol" is changed to "No animal shall drink alcohol
to excess", "No animal shall sleep in a bed" has been changed to "No animal shall sleep in a bed
with sheets", and "No animal shall kill another animal" is changed to "No animal shall kill another animal
without cause". Later all the commandments are replaced with one phrase: "All animals are equal
, but some animals are more equal than others". Once Napoleon gains control of Animal Farm he uses his guard dogs to attack Snowball, who flees to an unknown fate (in the 1954 film, he is killed), and manipulates the farm into believing what Snowball had done before was the cause of problems for the farm. Though Snowball had fought bravely for Animal Farm at the Battle of the Cowshed, Napoleon alters his account of the events to say Snowball had openly fought for Jones. Napoleon then conducts a purge of Snowball's supporters and has them executed as conspirators. ==Historical parallels with Trotsky==
