Napoleon, Snowball, and Squealer work together as leaders of Animal Farm in the early days after the animals take over the farm.

Snowball is a young boar who helps to create Animalism, the list of rules that set out the expectations for the residents of Animal Farm. He is a good organizer, assigning the animals to committees to help the farm flourish and grow, and develops many of the important strategies that allow the animals to repel Jones and the other humans when the people attempt to recapture control of the farm. Snowball is eventually driven off the farm by Napoleon, and association with him or his ideas becomes a crime punishable by death.

Squealer is the chief explanation-provider for the animals, which evolves into being in charge of presenting the propaganda and brainwashing that keeps the lower animals in line and obediant to the animals-in-charge. Squealer is most interested in preserving his own position of power and prestige, and will support any position or policy that works toward that end.

Napoleon leads the revolution against the humans in cooperation with Snowball and Squealer, but forces Snowball off the farm and moves Squealer into the position of propaganda chief, giving himself the position of supreme leader of Animal Farm. As time goes by, he becomes more and more isolated from the other animals, copying the mannerisms and corruptions of the humans that had been the enemy.

Moses is Jones's pet raven. The pigs allow him to remain after driving Jones and the other humans away from Animal Farm because he provides an escape for the animals, telling them of the far-off land of Sugarcandy Mountain which they could hope to reach in the future.

Identify Snowball, Napoleon, and Squealer in Animal Farm.

The pigs Snowball, Napoleon, and Squealer are leaders on the farm and in the beginning attempt to carry out the plans of Old Major.

Napoleon becomes a fierce leader who runs Snowball off the farm so that he can be in control of the other animals.  He says that he wants to educate the animals, but he actually indoctrinates them with his own ideas.  He orders the death other animals who profess to being Snowball's allies.

Snowball was the organizer who put the animals into groups based on their skills and abilities.  He planned the defense against the humans to uphold the system of Animalism.  After he is run off the farm by Napoleon, Napoleon uses Snowball as a scapegoat and blames many ills of the farm on Snowball.

Finally, Sqealer is the voice of propaganda in the story.  He has a story for everything, and gives explanations to the animals for all occurrences on the farm.  His aim is to keep the animals happy and to maintain their belief in Animalism.

In the allegory, the three represent Stalin, Trotsky, and propaganda, respectively.
