In states like Milan and Naples, where all political liberty had been destroyed, the only weapons of the oppressed were those the tyrant had taught them--intrigue and assassination. In cities like Florence, where constitutional forms remained but the spirit had fled, and where the state was torn by deadly feuds which vented themselves in cruel proscription and exile of the defeated, the people were inspired by mutual suspicion and deep political hatreds. To lose power was to lose everything. Hence men became desperate, forgot the necessity for patience, the duty of a minority, and sought to overthrow their enemies by secret conspiracy or open revolt. In the smaller states things were worse. There was even less stability, the factions were more bitter, the chance of successful revolt greater. No doubt Venice and the Papal Dominions were more stable than the rest of the Peninsula, but even there intrigue, corruption, and conspiracies were not uncommon. Amid such political circumstances as these, not only did all feeling of Italian nationality perish, but patriotism for city or kingdom died before the imperative instincts of self-preservation. The worship of success replaced devotion to principle and obedience to authority, while cleverness and selfishness flourished at the expense of morality. Moreover, to protect themselves or to pursue their schemes of conquest, the tyrants introduced the Condottieri. The republics, partly from indolence, partly from the difficulty of resisting the trained soldier with a half-disciplined militia, followed suit, and Italy became the victim of mercenaries. Of war these made a game: with no interest in the quarrels beyond their wage, or their individual ambitions, they loved the battlefield by which they lived, yet did not wish the battle to be decisive. Ever ready to change sides at the dictates of self-interest, or for higher pay, they set up and overthrew states and spread confusion around. Meanwhile the citizens forgot the art of war, and, when the moment of their trial came, finding themselves no match for the martial nations of the North, were frightened at the fury of their onslaught.
