content with its government, and who must therefore have been hostile to him, than of those who, from being malcontents under the previous government, became his friends, and favored his seizing the state.
It has been the general practice of princes, for the purpose of holding their states securely, to build fortresses to serve as a curb and check upon those who might make an attempt against the government, and at the same time to afford the prince a secure place of refuge against the first attack. I approve of this system, because it was practised by the ancients; and yet we have seen in our own times that Messer Niccolo Vitelli dismantled two fortresses in Citta di Castello, so as to enable him to hold that place. Guidobaldo, Duke of Urbino, on returning to his state, whence he had been driven by Cesar Borgia, razed all the fortresses of that province to their very foundations; for he thought that it would be more difficult for him to lose that state a second time without those fortresses. The Bentivogli did the same thing on their return to Bologna. Fortresses then are useful or not, according to circumstances; and whilst in one way they are advantageous, they may in another prove injurious to a prince. The question may therefore be stated thus. A prince who fears his own people more than he does foreigners should build fortresses; but he who has more cause to fear strangers than his own people should do without them. The citadel of Milan, built by Francesco Sforza, has caused, and will yet cause, more trouble to the house of Sforza than any other disturbance in that state. The best fortress which a prince can possess is the affection of his people; for even if he have fortresses, and is hated by his people, the fortresses will not save him; for when a people have once risen in arms against their prince, there will be no lack of strangers who will aid them.
In our own times we have seen but one instance where fortresses have been of advantage to a ruler, and that was the ease of the Countess of Furli, when her husband, the Count Girolamo, was killed; for the castle of Furli enabled her to escape from the fury of the people, and there to await assistance from Milan, so as to recover her state, the circumstances at the time being such that the people could not obtain assistance from strangers. Later, however, when she was assailed by Cesar Borgia, the people of Furli, being hostile to her, united
