Final answer:
Old Major symbolizes revolution and inspires the animals to rebel against their human oppressors in Animal Farm. His ideas shape the principles of Animalism, but his death leaves the animals without his guidance, leading to the rise of the manipulative pigs.
Step-by-step explanation:
Old Major's role in Animal Farm is to serve as a symbol of revolution and inspire the other animals to rebel against their human oppressors. He represents Karl Marx or Vladimir Lenin, the founders of communism, and his speech about the injustices of human rule serves as the basis for the animals' rebellion.
Old Major's role is also significant because his ideas ultimately shape the principles of Animalism, which become the foundation of the animal-led society on the farm.
However, Old Major's death shortly after his speech leaves the other animals without his guidance, leading to the rise of the manipulative and corrupt pigs.
Old Major's character highlights the themes of idealism, revolution, and the dangers of charismatic leaders in George Orwell's Animal Farm.
