Discourses on Livy

That an usurper is never safe in his princedom while those live whom he has deprived of it.

From what befell the elder Tarquin at the hands of the sons of Ancus, and Servius Tullius at the hands of Tarquin the proud, we see what an arduous and perilous course it is to strip a king of his kingdom and yet suffer him to live on, hoping to conciliate him by benefits. We see, too, how the elder Tarquin was ruined by his belief that he held the kingdom by a just title, since it had been given him by the people and confirmed to him by the senate, never suspecting that the sons of Ancus would be so stirred by resentment that it would be impossible to content them with what contented all the rest of Rome. Servius Tullius again, was ruined through believing that he could conciliate the sons of Ancus by loading them with favours.
