Answer:
Animal Farm allegorizes the rise to power of the dictator Joseph Stalin. In the novella, the overthrow of the human oppressor Mr. Jones by a democratic coalition of animals quickly gives way to the consolidation of power among the pigs. Much like the Soviet intelligentsia, the pigs establish themselves as the ruling class in the new society.
Step-by-step explanation:
Squealer takes the central role in making announcements to the animals. Napoleon appears less and less often as the book progresses. Near the start of the book, it is said that he was very convincing and could turn "black into white". This foreshadows several euphemisms he uses to maintain the control of the barn through difficult times. He is Napoleon's (Stalin's) key to propaganda for the farm (Soviet Union).
