How does napoleon exploit the lower animals in the book Animal Farm by George Orwell?

Napoleon was a pig in more than one sense. Words that you associate with pigs are not often pleasant. ‘Pig' referring to one who is greedy and has more than their fair share; ‘pig headed' refers to one who is extremely stubborn and thinks they are always right; ‘the pigs' refer to police, or other figures of authority. Napoleon became dictator of Animal Farm merely due to the fact that he was a pig, and had the simplest of leadership skills. He maintained that power by Propaganda and running the farm in a fascist, totalitarian manner. Violence, propaganda and the general ignorance of the other farm animals were major roles in keeping Napoleon in power.

FIGHT THE POWER!! :P
