When the dogs drive out snowball from the farm, it shows the animals how powerful the dogs are. This demonstrates fear because the animals become scared that this could happen to them. This tactic works well because the animals know that if they ever question anything or rebel against something that is unfair, they will be given to the dogs. This also allows Napoleon to gain and maintain control because the animals are too terrified to speak up and rebel against Napoleon. The animals also know from the previous event that the dogs work on Napoleon’s command therefore if they disobey snowball, they will have to deal with the dogs. Using fear is one tactic that helps Napoleon gain and maintain control of Animal Farm. Another reason why Napoleon is able to gain and maintain control of the animals is because he uses propaganda to convince the animals to follow him. Squealer acts as the propaganda department of the farm. He helps Napoleon gain and maintain the acceptance of the farm animals by convincing the animals of false things. For example, Squealer convinces the animals that the pigs need the milk and the apples more than the other animals, and that leadership is a burden and so the animals should be happy that Napoleon is taking on the burden for them.
