Consequently, however, the farm is left in dire poverty. Not long afterwards a conflict emerges between Snowball and Napoleon. Napoleon then takes up Snowball's plan for the windmill as his own. A hard life begins for the animals. Back-breaking labour is imposed on them by Napoleon.
Food supplies become ever more meagre.
A system of terror and constant threat from Napoleon's dogs is built up, while Napoleon allows himself to be feted as a great leader and a grotesque personality cult is put into place. One after the other of the originally formulated seven principles are betrayed by Napoleon and his clique. They lay the groundwork for this by changing the original law. Of course it is Napoleon and his cronies who determine what reasons are valid. At the end of Orwell's book it is impossible to tell the difference between the ruling pigs and man.
