And, to reduce the matter into a small compass, I say that, on the side of the conspirator, there is nothing but fear, jealousy, prospect of punishment to terrify him; but on the side of the prince there is the majesty of the principality, the laws, the protection of friends and the state to defend him; so that, adding to all these things the popular goodwill, it is impossible that any one should be so rash as to conspire. For whereas in general the conspirator has to fear before the execution of his plot, in this case he has also to fear the sequel to the crime; because on account of it he has the people for an enemy, and thus cannot hope for any escape.
Endless examples could be given on this subject, but I will be content with one, brought to pass within the memory of our fathers. Messer Annibale Bentivogli, who was prince in Bologna (grandfather of the present Annibale), having been murdered by the Canneschi, who had conspired against him, not one of his family survived but Messer Giovanni,(*) who was in childhood: immediately after his assassination the people rose and murdered all the Canneschi. This sprung from the popular goodwill which the house of Bentivogli enjoyed in those days in Bologna; which was so great that, although none remained there after the death of Annibale who was able to rule the state, the Bolognese, having information that there was one of the Bentivogli family in Florence, who up to that time had been considered the son of a blacksmith, sent to Florence for him and gave him the government of their city, and it was ruled by him until Messer Giovanni came in due course to the government.
(*) Giovanni Bentivogli, born in Bologna 1438, died at Milan 1508. He ruled Bologna from 1462 to 1506. Machiavelli’s strong condemnation of conspiracies may get its edge from his own very recent experience (February 1513), when he had been arrested and tortured for his alleged complicity in the Boscoli conspiracy.
For this reason I consider that a prince ought to reckon conspiracies of little account when his people hold him in esteem; but when it is hostile to him, and bears hatred towards him, he ought to fear everything and everybody. And well-ordered states and wise princes have taken every care not to drive the nobles to desperation, and to keep the people satisfied and contented, for this is one of the most important objects a prince can have.
