It now only remains for us to consider those dangers which follow after the execution of a plot. These in fact resolve themselves into one, namely, that some should survive who will avenge the death of the murdered prince. The part of avenger is likely to be assumed by a son, a brother, or other kinsman of the deceased, who in the ordinary course of events might have looked to succeed to the princedom. And such persons are suffered to live, either from inadvertence, or from some of the causes noted already, as when Giovann’ Andrea of Lampognano, with the help of his companions, put to death the Duke of Milan. For the son and two brothers of the Duke, who survived him, were able to avenge his death. In cases like this, indeed, the conspirators may be held excused, since there is nothing they can do to help themselves. But when from carelessness and want of due caution some one is allowed to live whose death ought to have been secured, there is no excuse. Certain conspirators, after murdering the lord, Count Girolamo of Forli, made prisoners of his wife and of his children who were still very young. By thinking they could not be safe unless they got possession of the citadel, which the governor refused to surrender, they obtained a promise from Madonna Caterina, for so the Countess was named, that on their permitting her to enter the citadel she would cause it to be given up to them, her children in the mean time remaining with them as hostages. On which undertaking they suffered her to enter the citadel. But no sooner had she got inside than she fell to upbraid them from the walls with the murder of her husband, and to threaten them with every kind of vengeance; and to show them how little store she set upon her children, told them scoffingly that she knew how others could be got. In the end, the rebels having no leader to advise them, and perceiving too late the error into which they had been betrayed, had to pay the penalty of their rashness by perpetual banishment.

But of all the dangers which may follow on the execution of a plot, none is so much or so justly to be feared as that the people should be well affected to the prince whom you have put to death. For against this danger conspirators have no resource which can ensure their safety. Of this we have example in the case of Cæsar, who as he had the love of the Roman people was by them avenged; for they it was who, by driving out the conspirators from Rome, were the cause that all of them, at different times and in different places, came to violent ends.

Conspiracies against their country are less danger for those who take part in them than conspiracies against princes; since there is less risk beforehand, and though there be the same danger in their execution, there is none afterwards. Beforehand, the risks are few, because a citizen may use means for obtaining power without betraying his wishes or designs to any; and unless his course be arrested, his designs are likely enough to succeed; nay, though laws be passed to restrain him, he may strike out a new path. This is to be understood of a commonwealth which has to some degree become corrupted; for in one wherein there is no taint of corruption, there being no soil in which evil seed can grow, such designs will never suggest themselves to any citizen.

In a commonwealth, therefore, a citizen may by many means and in many ways aspire to the princedom without risking destruction, both because republics are slower than princes are to take alarm, are less suspicious and consequently less cautious, and because they look with greater reverence upon their great citizens, who are in this way rendered bolder and more reckless in attacking them. Any one who has read Sallust’s account of the conspiracy of Catiline, must remember how, when that conspiracy was discovered, Catiline not only remained in Rome, but even made his appearance in the senatehouse, where he was suffered to address the senate in the most insulting terms,—so scrupulous was that city in protecting the liberty of all its citizens. Nay, even after he had left Rome and placed himself at the head of his army, Lentulus and his other accomplices would not have been imprisoned, had not letters been found upon them clearly establishing their guilt. Hanno, the foremost citizen of Carthage, aspiring to absolute power, on the occasion of the marriage of a daughter contrived a plot for administering poison to the whole senate and so making himself prince. The scheme being discovered, the senate took no steps against him beyond passing a law to limit the expense of banquets and marriage ceremonies. So great was the respect they paid to his quality.

True, the execution of a plot against your country is attended with greater difficulty and danger, since it seldom happens that, in conspiring against so many, your own resources are sufficient by themselves; for it is not every one who, like Cæsar, Agathocles, or Cleomenes, is at the head of an army, so as to be able at a stroke, and by open force to make himself master of his country. To such as these, doubtless, the path is safe and easy enough; but others who have not such an assembled force ready at their command, must effect their ends either by stratagem and fraud, or with the help of foreign troops. Of such stratagems and frauds we have an instance in the case of Pisistratus the Athenian, who after defeating the Megarians and thereby gaining the favour of his fellow-citizens, showed himself to them one morning covered with wounds and blood, declaring that he had been thus outraged through the jealousy of the nobles, and asking that he might have an armed guard assigned for his protection. With the authority which this lent him, he easily rose to such a pitch of power as to become tyrant of Athens. In like manner Pandolfo Petrucci, on his return with the other exiles to Siena, was appointed the command of the public guard, as a mere office of routine which others had declined. Very soon, however, this armed force gave him so much importance that he became the supreme ruler of the State. And many others have followed other plans and methods, and in the course of time, and without incurring danger, have achieved their aim.

Conspirators against their country, whether trusting to their own forces or to foreign aid, have had more or less success in proportion as they have been favoured by Fortune. Catiline, of whom we spoke just now, was overthrown. Hanno, who has also been mentioned, failing to accomplish his object by poison, armed his partisans to the number of many thousands; but both he and they came to an ill end. On the other hand, certain citizens of Thebes conspiring to become its tyrants, summoned a Spartan army to their assistance, and usurped the absolute control of the city. In short, if we examine all the conspiracies which men have engaged in against their country, we shall find that few or none have been quelled in their inception, but that all have either succeeded, or have broken down in their execution. Once executed, they entail no further risks beyond those implied in the nature of a princedom. For the man who becomes a tyrant incurs all the natural and ordinary dangers in which a tyranny involves him, and has no remedies against them save those of which I have already spoken.

This is all that occurs to me to say on the subject of conspiracies. If I have noticed those which have been carried out with the sword rather than those wherein poison has been the instrument, it is because, generally speaking, the method of proceeding is the same in both. It is true, nevertheless, that conspiracies which are to be carried out by poison are, by reason of their uncertainty, attended by greater danger. For since fewer opportunities offer for their execution, you must have an understanding with persons who can command opportunities. But it is dangerous to have to depend on others. Again, many causes may hinder a poisoned draught from proving mortal; as when the murderers of Commodus, on his vomiting the poison given him, had to strangle him.

Princes, then, have no worse enemy than conspiracy, for when a conspiracy is formed against them, it either carries them off, or discredits them: since, if it succeeds, they die; while, if it be discovered, and the conspirators be put to death themselves, it will always be believed that the whole affair has been trumped up by the prince that he might glut his greed and cruelty with the goods and blood of those whom he has made away with. Let me not, however, forget to warn the prince or commonwealth against whom a conspiracy is directed, that on getting word of it, and before taking any steps to punish it, they endeavour, as far as they can, to ascertain its character, and after carefully weighing the strength of the conspirators with their own, on finding it preponderate, never suffer their knowledge of the plot to appear until they are ready with a force sufficient to crush it. For otherwise, to disclose their knowledge will only give the signal for their destruction. They must strive therefore to seem unconscious of what is going on; for conspirators who see themselves detected are driven forward by necessity and will stick at nothing. Of this precaution we have an example in Roman history, when the officers of the two legions, who, as has already been mentioned, were left behind to defend the Capuans from the Samnites, conspired together against the Capuans. For on rumours of this conspiracy reaching Rome, Rutilius the new consul was charged to see to it; who, not to excite the suspicions of the conspirators, publicly gave out that by order of the senate the Capuan legions were continued in their station. The conspirators believing this, and thinking they would have ample time to execute their plans, made no effort to hasten matters, but remained at their ease, until they found that the consul was moving one of the two legions to a distance from the other. This arousing their suspicion, led them to disclose their designs and endeavour to carry them out.

Now, we could have no more instructive example than this in whatever way we look at it. For it shows how slow men are to move in those matters wherein time seems of little importance, and how active they become when necessity urges them. Nor can a prince or commonwealth desiring for their own ends to retard the execution of a conspiracy, use any more effectual means to do so, than by artfully holding out to the conspirators some special opportunity as likely soon to present itself; awaiting which, and believing they have time and to spare for what they have to do, they will afford that prince or commonwealth all the leisure needed to prepare for their punishment. Whosoever neglects these precautions hastens his own destruction, as happened with the Duke of Athens, and with Guglielmo de’ Pazzi. For the Duke, who had made himself tyrant of Florence, on learning that he was being conspired against, without further inquiry into the matter, caused one of the conspirators to be seized; whereupon the rest at once armed themselves and deprived him of his government. Guglielmo, again, being commissary in the Val di Chiana in the year 1501, and learning that a conspiracy was being hatched in Arezzo to take the town from the Florentines and give it over to the Vitelli, repaired thither with all haste; and without providing himself with the necessary forces or giving a thought to the strength of the conspirators, on the advice of the bishop, his son, had one of them arrested. Which becoming known to the others, they forthwith rushed to arms, and taking the town from the Florentines, made Guglielmo their prisoner. Where, however, conspiracies are weak, they may and should be put down without scruple or hesitation.

Two methods, somewhat opposed to one another, which have occasionally been followed in dealing with conspiracies, are in no way to be commended. One of these was that adopted by the Duke of Athens, of whom I have just now spoken, who to have it thought that he confided in the goodwill of the Florentines, caused a certain man who gave information of a plot against him, to be put to death. The other was that followed by Dion the Syracusan, who, to sound the intentions of one whom he suspected, arranged with Calippus, whom he trusted, to pretend to get up a conspiracy against him. Neither of these tyrants reaped any advantage from the course he followed. For the one discouraged informers and gave heart to those who were disposed to conspire, the other prepared an easy road to his own death, or rather was prime mover in a conspiracy against himself. As the event showed. For Calippus having free leave to plot against Dion, plotted to such effect, that he deprived him at once of his State and life.
