is no sure method of holding them except by ruining them. And whoever becomes the ruler of a free city and does not destroy it, can expect to be destroyed by it, for it can always find a motive for rebellion in the name of liberty and of its ancient usages, which are forgotten neither by lapse of time nor by benefits received, and whatever one does or provides, so long as the inhabitants are not separated or dispersed, they do not forget that name and those usages, but appeal to them at once in every emergency, as did Pisa after being so many years held in servitude by the Florentines. But when cities or provinces have been accustomed to live under a prince, and the family of that prince is extinguished, being on the one hand used to obey, and on the other not having their old prince, they cannot unite in choosing one from among themselves, and they do not know how to live in freedom, so that they are slower to take arms, and a prince can win them over with greater facility and establish himself securely. But in republics there is greater life, greater hatred, and more desire for vengeance; they do not and cannot cast aside the memory of their ancient liberty, so that the surest way is either to destroy them or reside in them.
