Almost all the great emigrations of nations have been and continue to be from the cold and barren region of Scythia, because from the population there being excessive, and the soil ill able to support them, they are forced to quit their home, many causes operating to drive them forth and none to keep them back. And if, for the last five hundred years, it has not happened that any of these nations has actually overrun another country, there are various reasons to account for it. First, the great clearance which that region made of its inhabitants during the decline of the Roman Empire, when more than thirty nations issued from it in succession; and next, the circumstance that the countries of Germany and Hungary, whence also these nations came, are now so much improved that men can live there in comfort, and consequently are not constrained to shift their habitations. Besides which, since these countries are occupied by a very warlike race, they serve as a sort of bulwark to keep back the neighbouring Scythians, who for this reason do not venture to attack them, nor attempt to force a passage. Nevertheless, movements on a great scale have oftentimes been begun by the Tartars, and been at once withstood by the Hungarians and Poles, whose frequent boast it is, that but for them, Italy and the Church would more than once have felt the weight of the Tartar arms.

Of the nations of whom I have been speaking, I shall now say no more.

CHAPTER IX.—Of the Causes which commonly give rise to Wars between States.

The occasion which led to war between the Romans and Samnites, who for long had been in league with one another, is of common occurrence in all powerful States, being either brought about by accident, or else purposely contrived by some one who would set war a-foot. As between the Romans and the Samnites, the occasion of war was accidental. For in making war upon the Sidicinians and afterwards on the Campanians, the Samnites had no thought of involving themselves with the Romans. But the Campanians being overpowered, and, contrary to the expectation of Romans and Samnites alike, resorting to Rome for aid, the Romans, on whose protection they threw themselves, were forced to succour them as dependants, and to accept a war which, it seemed to them, they could not with honour decline. For though they might have thought it unreasonable to be called on to defend the Campanians as friends against their own friends the Samnites, it seemed to them shameful not to defend them as subjects, or as a people who had placed themselves under their protection. For they reasoned that to decline their defence would close the gate against all others who at any future time might desire to submit themselves to their power. And, accordingly, since glory and empire, and not peace, were the ends which they always had in view, it became impossible for them to refuse this protectorship.

A similar circumstance gave rise to the first war with the Carthaginians, namely the protectorate assumed by the Romans of the citizens of Messina in Sicily, and this likewise came about by chance. But the second war with Carthage was not the result of chance. For Hannibal the Carthaginian general attacked the Saguntans, who were the friends of Rome in Spain, not from any desire to injure them, but in order to set the arms of Rome in motion, and so gain an opportunity of engaging the Romans in a war, and passing on into Italy. This method of picking a quarrel is constantly resorted to by powerful States when they are bound by scruples of honour or like considerations. For if I desire to make war on a prince with whom I am under an ancient and binding treaty, I shall find some colour or pretext for attacking the friend of that prince, very well knowing that when I attack his friend, either the prince will resent it, when my scheme for engaging him in war will be realized; or that, should he not resent it, his weakness or baseness in not defending one who is under his protection will be made apparent; either of which alternatives will discredit him, and further my designs.

We are to note, therefore, in connection with this submission of the Campanians, what has just now been said as to provoking another power to war; and also the remedy open to a State which, being unequal to its own defence, is prepared to go all lengths to ruin its assailant,—that remedy being to give itself up unreservedly to some one whom it selects for its defender; as the Campanians gave themselves up to the Romans, and as the Florentines gave themselves up to King Robert of Naples, who, after refusing to defend them as his friends against Castruccio of Lucca by whom they were hard pressed, defended them as his subjects.

CHAPTER X.—That contrary to the vulgar opinion, Money is not the Sinews of War.

Since any man may begin a war at his pleasure, but cannot at his pleasure bring it to a close, a prince before he engages in any warlike enterprise ought to measure his strength and govern himself accordingly. But he must be prudent enough not to deceive himself as to his strength, which he will always do, if he measure it by money, by advantage of position, or by the good-will of his subjects, while he is unprovided with an army of his own. These are things which may swell your strength but do not constitute it, being in themselves null and of no avail without an army on which you can depend.

Without such an army no amount of money will meet your wants, the natural strength of your country will not protect you, and the fidelity and attachment of your subjects will not endure, since it is impossible that they should continue true to you when you cannot defend them. Lakes, and mountains, and the most inaccessible strongholds, where valiant defenders are wanting, become no better than the level plain; and money, so far from being a safeguard, is more likely to leave you a prey to your enemy; since nothing can be falser than the vulgar opinion which affirms it to be the sinews of war.

This opinion is put forward by Quintus Curtius, where, in speaking of the war between Antipater the Macedonian and the King of Sparta, he relates that the latter, from want of money, was constrained to give battle and was defeated; whereas, could he have put off fighting for a few days the news of Alexander’s death would have reached Greece, and he might have had a victory without a battle. But lacking money, and fearing that on that account his soldiers might desert him, he was forced to hazard an engagement. It was for this reason that Quintus Curtius declared money to be the sinews of war, a maxim every day cited and acted upon by princes less wise than they should be. For building upon this, they think it enough for their defence to have laid up great treasures; not reflecting that were great treasures all that is needed for victory, Darius of old had conquered Alexander, the Greeks the Romans, and in our own times Charles of Burgundy the Swiss; while the pope and the Florentines together would have had little difficulty in defeating Francesco Maria, nephew of Pope Julius II., in the recent war of Urbino; and yet, in every one of these instances, the victory remained with him who held the sinews of war to consist, not in money, but in good soldiers.
