There are many themes in Animal Farm, but some of the most prominent ones include:
The corrupting influence of power: Throughout the novel, the pigs, who are the most intelligent animals on the farm and who take on leadership roles, begin to abuse their power and exploit the other animals for their own benefit. This theme illustrates the dangers of unchecked power and the importance of holding leaders accountable.
The danger of blindly following ideological leaders: The animals on the farm are initially inspired by the ideas of Old Major, the old boar who advocates for animal rights and equality. However, after Old Major dies, the pigs take his ideas and twist them to suit their own purposes, using propaganda and censorship to control the other animals and maintain their power. This theme highlights the importance of critical thinking and the dangers of blindly following leaders who may not have the best interests of their followers at heart.
