When the rebellion took place, it started off well, but there was a conflict among the leadership.  Napoleon finally drove out Snowball.  This act was another reason why the farm failed, because of the two pigs, Snowball was the more intelligent, better organizer, and the one who had a vision.

However, the greatest reason for the failure on the farm, in my opinion, is rooted in Napoleon’s plan for the farm.  Absolute power corrupts absolutely.  When Napoleon took complete control of the farm and introduced a reign of terror, he guaranteed that the farm would fail.  In fact, by the end of the story, we come back to where the story started, as Napoleon becomes a corrupt man, indistinguishable from a human.
