Final answer:
In George Orwell's 'Animal Farm', the pigs use propaganda, misinformation, and intimidation to keep the animals unified and under control, similar to tactics employed by totalitarian regimes.
Step-by-step explanation:
The major tactics used by the pigs to maintain unity and control among the animals, as described in George Orwell's Animal Farm, include propaganda, misinformation, and the use of fear. Propaganda is used to create a common enemy and to glorify the pigs' leadership. Misinformation and the manipulation of language help to confuse and control the thoughts of the other animals. Lastly, intimidation and brutality are utilized to suppress dissent and keep the animals in line, ensuring that they are too fearful to challenge the pigs' authority. These tactics are reminiscent of the strategies used by totalitarian regimes to perpetuate their power.
