Niccolo Machiavelli Quotes
Some princes, so as to hold securely the state, have disarmed their subjects, others have kept their subject towns distracted by factions...Our forefathers, and those who were reckoned wise, were accustomed to say that it was necessary to hold Pistoia [an Italian city] by factions and Pisa by fortress, and with this idea they fostered quarrels in some of their tributary towns so as to keep possession of them the more easily.
