The author posits that arming one's subjects is a strategic necessity for new princes, as it transforms distrusted individuals into loyal adherents and defenders.
Arming Your Subjects
Niccolo Machiavelli
The Prince...ns distracted by factions; others have fostered enmities against themselves; others have laid themselves out to gain over those whom they distrusted in the beginning of their governments; some have built fortresses; some have overthrown and destroyed them. And although one cannot give a final judgment on all of these things unless one possesses the particulars of those states in which a decision has to be made, nevertheless I will speak as comprehensively as the matter of itself will admit. 2.
There never was a new prince who has disarmed his subjects; rather when he has found them disarmed he has always armed them, because, by arming them, those arms become yours, those men who were distrusted become faithful, and those who were faithful are kept so, and your subjects become your adherents. And whereas all subjects cannot be armed, yet when those whom you do arm are benefited, the others can be handled more freely, and this difference in their treatment, which they quite understand, makes the former your dependents, and the latter, considering it to be necessary that those who have the most danger and service should have the most reward, excuse you.
But when you disarm them, you at once offend them by showing that you distrust them, either for cowardice or for want of loyalty, and either of these opinions breeds hatred against you. And because you cannot remain unarmed, it follows that you turn to mercenaries, which are of the character already shown; even if they should be good they would not be sufficient to defend you against powerful enemies and distrusted subjects. Therefore, as I have said, a new prince in a new principality has alwa...

⚖Mercenaries vs Auxiliaries

Niccolo Machiavelli
The PrinceA prescription warning against the use of auxiliary and mercenary troops, arguing that their inherent qualities make them more dangerous to the prince than to the enemy.
...o his auxiliaries, he having conquered by other arms than theirs. The Florentines, being entirely without arms, sent ten thousand Frenchmen to take Pisa, whereby they ran more danger than at any other time of their troubles. The Emperor of Constantinople,[2] to oppose his neighbours, sent ten thousand Turks into Greece, who, on the war being finished, were not willing to quit; this was the beginning of the servitude of Greece to the infidels. [2] Joannes Cantacuzenus, born 1300, died 1383.
Therefore, let him who has no desire to conquer make use of these arms, for they are much more hazardous than mercenaries, because with them the ruin is ready made; they are all united, all yield obedience to others; but with mercenaries, when they have conquered, more time and better opportunities are needed to injure you; they are not all of one community, they are found and paid by you, and a third party, which you have made their head, is not able all at once to assume enough authority to injure you. In conclusion, in mercenaries dastardy is most dangerous; in auxiliaries, valour.
The wise prince, therefore, has always avoided these arms and turned to his own; and has been willing rather to lose with them than to conquer with the others, not deeming that a real victory which is gained with the arms of others. I shall never hesitate to cite Cesare Borgia and his actions. This duke entered the Romagna with auxiliaries, taking there only French soldiers, and with them he captured Imola and Forli; but afterwards, such forces not appearing to him reliable, he turned to merce...

⚖Mercenary Captain's Risk

Niccolo Machiavelli
The PrinceThe author criticizes the use of mercenary captains, arguing they are either dangerously ambitious or incompetently ruinous, and insists that a prince must lead his own army in person.
...y for him to send his quartermasters to chalk up the billets for his soldiers to conquer the country. Cf. “The History of Henry VII,” by Lord Bacon: “King Charles had conquered the realm of Naples, and lost it again, in a kind of a felicity of a dream. He passed the whole length of Italy without resistance: so that it was true what Pope Alexander was wont to say: That the Frenchmen came into Italy with chalk in their hands, to mark up their lodgings, rather than with swords to fight.”
I wish to demonstrate further the infelicity of these arms. The mercenary captains are either capable men or they are not; if they are, you cannot trust them, because they always aspire to their own greatness, either by oppressing you, who are their master, or others contrary to your intentions; but if the captain is not skilful, you are ruined in the usual way. And if it be urged that whoever is armed will act in the same way, whether mercenary or not, I reply that when arms have to be resorted to, either by a prince or a republic, then the prince ought to go in person and perform the duty of a captain; the republic has to send its citizens,…
And experience has shown princes and republics, single-handed, making the greatest progress, and mercenaries doing nothing except damage; and it is more difficult to bring a republic, armed with its own arms, under the sway of one of its citizens than it is to bring one armed with foreign arms. Rome and Sparta stood for many ages armed and free. The Switzers are completely armed and quite free. Of ancient mercenaries, for example, there are the Carthaginians, who were oppressed by their mercen...

⚖The Art of War

Niccolo Machiavelli
The PrinceA prescription stating that a ruler's primary and sole focus should be the art of war, as military proficiency is the foundation of both acquiring and retaining political power.
...es are those which are composed either of subjects, citizens, or dependents; all others are mercenaries or auxiliaries. And the way to make ready one’s own forces will be easily found if the rules suggested by me shall be reflected upon, and if one will consider how Philip, the father of Alexander the Great, and many republics and princes have armed and organized themselves, to which rules I entirely commit myself. CHAPTER XIV. THAT WHICH CONCERNS A PRINCE ON THE SUBJECT OF THE ART OF WAR
A prince ought to have no other aim or thought, nor select anything else for his study, than war and its rules and discipline; for this is the sole art that belongs to him who rules, and it is of such force that it not only upholds those who are born princes, but it often enables men to rise from a private station to that rank. And, on the contrary, it is seen that when princes have thought more of ease than of arms they have lost their states. And the first cause of your losing it is to neglect this art; and what enables you to acquire a state is to be master of the art. Francesco Sforza, through being martial, from a private person became…
Because there is nothing proportionate between the armed and the unarmed; and it is not reasonable that he who is armed should yield obedience willingly to him who is unarmed, or that the unarmed man should be secure among armed servants. Because, there being in the one disdain and in the other suspicion, it is not possible for them to work well together. And therefore a prince who does not understand the art of war, over and above the other misfortunes already mentioned, cannot be respected by...

⚖The Auxiliary Trap

Niccolo Machiavelli
The PrinceThe author argues that auxiliary troops are inherently dangerous for a prince; if they lose, the prince is defeated, and if they win, the prince becomes their prisoner.
...tockade or ditch, nor did they campaign in the winter. All these things were permitted by their military rules, and devised by them to avoid, as I have said, both fatigue and dangers; thus they have brought Italy to slavery and contempt. [8] Alberigo da Conio. Alberico da Barbiano, Count of Cunio in Romagna. He was the leader of the famous “Company of St George,” composed entirely of Italian soldiers. He died in 1409. CHAPTER XIII. CONCERNING AUXILIARIES, MIXED SOLDIERY, AND ONE’S OWN
Auxiliaries, which are the other useless arm, are employed when a prince is called in with his forces to aid and defend, as was done by Pope Julius in the most recent times; for he, having, in the enterprise against Ferrara, had poor proof of his mercenaries, turned to auxiliaries, and stipulated with Ferdinand, King of Spain, for his assistance with men and arms. These arms may be useful and good in themselves, but for him who calls them in they are always disadvantageous; for losing, one is undone, and winning, one is their captive.
[1] Ferdinand V (F. II of Aragon and Sicily, F. III of Naples), surnamed “The Catholic,” born 1452, died 1516. And although ancient histories may be full of examples, I do not wish to leave this recent one of Pope Julius the Second, the peril of which cannot fail to be perceived; for he, wishing to get Ferrara, threw himself entirely into the hands of the foreigner. But his good fortune brought about a third event, so that he did not reap the fruit of his rash choice; because, having his au...
