What are the different causes of the animals' rebellion in Animal Farm by George Orwell?

To a great
extent, the animals who rebel do so out of opposition to 's actions as leader.  There are some
areas where there are differences as to why they decide to rebel or openly question his actions,
but most of it boils down to dislike of Napoleon as leader.  For example, three hens consider it
murder that Napoleon demands that they surrender their eggs in order to fulfill the arrangements
he has made with Whymper.  In destroying their eggs, this represents an act of rebellion.  When
Napoleon wants to end Sunday meetings, some porkers disagree.  In their dissent, another act of
"rebellion" is construed.  Whenquestions 's retelling of history in suggesting that
Snowball was actually treasonous to the ends of , it is seen as an act of rebellion.  This
becomes broadened to any animal that engages in a collaboration of any kind with Snowball.  The
cause of these associations are the belief that Snowball could be a better leader and possesses
better ideas than Napoleon.  In the end, the dissatisfaction with Napoleon in the fundamental
cause of rebellion, its perceived end and its actual result.  This is something that in either
form Napoleon strikes down with intensity and force, as seen in chapter seven when Napoleon
coordinates public confessions and demonstrates public execution in the most brutal of
fashion.
