And as experience shows, many have been the conspiracies, but few have been successful; because he who conspires cannot act alone, nor can he take a companion except from those whom he believes to be malcontents, and as soon as you have opened your mind to a malcontent you have given him the material with which to content himself, for by denouncing you he can look for every advantage; so that, seeing the gain from this course to be assured, and seeing the other to be doubtful and full of dangers, he must be a very rare friend, or a thoroughly obstinate enemy of the prince, to keep faith with you.
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.
