CHAP. XXIV.
That in the generality, Castles and Citadels, do more mischief than good.
TO the States-men of our times, it may perhaps seem indiscretion or inadvertancy in the Romans, that being desirous to keep Latium, and Privernum in subjection, they built neither Castles nor Citadels to secure them: and indeed they differed exceedingly from our Florentine Politicians, who are of opinion that not only Pisa, but all other Cities whatever are to be kept under that way, and surely had the Romans been like us, they would have been of the same opinion; but differing in their courage, their judgment, and their power, they differed likewise in their resolutions. Nor during all the time of their liberty, were the Româns known to build any Castle or Citadel to keep any City in awe, or any Province in peace; only some indeed which were fortified before, they garrisoned, and continued; which being so, and quite contrary to the Sentiment of our times, I think it not amiss, if in this place I inquire whether such things be profitable or unprofitable to the persons who build them. It is therefore to be considered, that such Fortresses are erected, either to repel an Enemy, or restrain a Subject, and keep him in obedience. In the first case I do pronounce them unnecessary; in the second dangerous. They are dangerous, and do rather obstruct than promote obedience in the Subject; because the great danger of Rebellion proceeds from hatred which the people have conceived against their Prince, that hatred proceeds from his injustice to the people, and he is said to be unjust when he governs them arbitrarily, and by force, which is never so manifest, as when he builds such Ca∣stles and Citadels among them, that no man might be able in any manner to oppose him. Which being so, those kind of Fortifications are not only useless and improper to keep the Subject in subjection; but dangerous, seeing by presumption upon them, Princes are en∣couraged to treat their Subjects worse than otherwise they would do, by which they con∣tract the odium of the people; and what is the consequence? Rebellion and Blood, and Confusion: Neither when troubles arise, and Wars break out, is there that defence or security in them, as is now adays imagined; for there are only two ways of keeping a conquered people in obedience, you must either have a standing Army (as the Romans had) always ready to subdue them; or you must divide, disperse, or destroy them in such manner, that they may never get together again to disturb you: For though you impo∣verish and plunder them never so much, Spoliatis arma supersunt, They will find Arms to revenge themselves; and if you disarm them never so carefully, Furor arma, ministrat. Their fury will supply them. If you cut off their Commanders, like Hydra's, others will succeed, and do as much mischief: If you build these Castles, in time of Peace they may be serviceable, and make you more bold, and secure against your Subjects; but when War comes, and both your Subjects and Enemies infest you, it is impossible they should defend you against both. And if ever they were useless, it is now since the use of Artille∣ry is known, against the fury of which no little Fort (from whence other Guns cannot play with security again, and where they want ground for repairing their breaches, or ma∣king new retrenchments upon occasion) can possibly stand: and being so, consider serious∣ly with your self whether these kind of Fortresses are like to keep your old Subjects, or your new Conquests in obedience? If your Territory be hereditary, and you have received it from your Ancestors, to build Castles to keep your own natural Subjects in obedience, will be to little purpose, for the reasons abovesaid, seeing they will be but a means to make you and your posterity the more Tyrannical, and by consequence expose you to the hatred of the people, against which they will be afterwards unable to defend you. So that for these reasons, that neither he himself nor his heirs may have occasion to entrench too much upon the people; and the people have no occasion to abhor him, a wise Prince will never build Citadels; and though Francesco Sforza Duke of Milan was reputed a wise Man, and built a Citadel at Milan to secure his Usurpations, yet his wisdom did not appear in that, for it proved afterwards the ruine of his posterity. For presuming upon that, they took the more confidence to oppress the people, which incensed them so highly, that they re∣volted upon the first approach of an Enemy, and turned their Prince out of that Province.
