Answer: To lessen the chance of revolt within the ruler's domain and ensure a prolonged reign.
Step-by-step explanation:
Machiavelli is one of the first to analyze the exercise of political power without any concern about morality. The Prince shows that Machiavelli firmly stated that human nature is genuinely corrupt and selfish. Hence, a prince needs to be feared to deter revolts. In this theory, the idea that no prince is able to always please all of his people leads to the recommendation for rulers to infuse fear in the people to avoid rebellion.
