What is the Irony behind the first commandment in animal farm?

The irony behind the first commandment in "Animal Farm," which states "All animals are equal," lies in the fact that, despite this declaration of equality, the pigs quickly establish themselves as the ruling class, ultimately becoming more equal than the other animals. As the story progresses, the pigs' actions contradict the commandment, leading to a society where the original ideals of equality are subverted. This highlights the hypocrisy of the leadership and the betrayal of the revolution's principles.
