Step-by-step explanation:
Squealer explains in chapter 7 of Animal Farm that the song 'Beasts of England' is abolished because its message no longer aligns with the new direction of the farm. The animals have achieved their initial goal of overthrowing the humans, and now the pigs are taking on leadership roles. They want the other animals to focus on their new commandments and the concept of Animalism rather than the idea of a future rebellion. The pigs also want to establish their own ideologies and emphasize their superiority over the other animals.
