Discuss the Irony of the book ANIMAL FARM and give one fact per sentence?

One irony in Animal Farm is that the animals overthrow their human oppressors to create a society where all animals are equal, but end up being ruled by a tyrannical pig named Napoleon.
The pigs, who were supposed to be the most intelligent and fair-minded animals, end up becoming corrupt and power-hungry, just like the humans they overthrew.
The animals believe they are working towards a utopian society, but end up living in a dictatorship where their rights are stripped away.
The pigs manipulate the other animals by changing the rules of the farm to benefit themselves, despite preaching equality and fairness.
The animals' revolution ultimately fails to bring about the freedom and equality they were fighting for, highlighting the irony of their situation.
