If the facts show that a government is more securely based on the confidence and support of the people than on the building of fortresses, then that must answer the argument over the merits of fortresses, widely debated in Machiavelli’s time, even though many rulers doubtless preferred to believe otherwise. Florence, with plenty of money and little stomach for fighting, wanted to believe that it could maintain itself by hiring mercenary troops, but the facts, again, proved that only the citizenry in arms could really be trusted.
