The story of Animal Farm is a satirical allegory about a group of farm animals who rebel against their human farmer and try to create a society of their own, but it soon descends into tyranny and corruption.
Symbolism in Animal Farm is extensive. Orwell uses the character of Old Major as a symbol of the initial revolutionary idea. He plants the seed of rebellion in the animals' minds. The pigs' transformation from comrades to dictators is symbolized by their changing behavior and appearance. For instance, they start walking on two legs like humans. The milk and apples that the pigs take for themselves symbolize the perks and privileges that the ruling class often appropriates for themselves. The animals' different reactions to these symbols show how a society can be divided and manipulated.
'Animal Farm' is a classic dystopian novel. It shows how the ideals of a revolution can be corrupted. The pigs, who take over the farm, gradually become as bad as the humans they overthrew. For example, Napoleon uses his power to oppress the other animals and rewrite the rules for his own benefit.
Animal Farm by George Orwell is a classic satirical novella. It presents a cautionary tale about the abuse of power and the manipulation of the masses in a fictional farm setting.
It's possible that Orwell titled the novel this way to draw attention to the hierarchical and often unjust nature of human societies, comparing them to a farm where animals have different statuses and struggles.
