What different types of opposition to Napoleon are there, and how are they dealt with?
The first type of opposition to Napoleon is philosophical. Both Snowball and Napoleon differ in their vision for Animal Farm. Snowball wants to send pigeons to neighboring farms to spread the revolution. Napoleon was to make Animal Farm strong militarily by gaining weapons and training the animals. Their biggest difference is over the building of the windmill. When Napoleon is about to lose the fight and Snowball's plan is about to be approved, Napoleon brings out his dogs and scares Snowball away.
The second type of opposition comes from animals who might have supported Snowball. Napoleon holds a "confessional meeting" and executes all who confess.
The third type of opposition comes when the Napoleon changes the rules and the animals question it. His answer comes through Squealer, who simply rewrites the rules and commandments.
The fourth type of opposition comes from the elements themselves. The windmill is blown down during a storm. Instead of suggesting this was caused by poor workmanship, Napoleon makes Snowball the "scapegoat" for everything. After this incident, anything that goes wrong is Snowball's fault.
The final opposition comes from economic problems at Animal Farm. Napoleon deasl with this by making alliances with humans on other farms, something the commandments forbid. However, Napoleon simply rewrites history and then withholds food from any animal, including the hens, who refuse to go along with his plan.
