With the confirmation and consolidation of these estates into a kingdom under Charlemagne in the ninth century the Papacy completed its moral aberration. Most of the Popes were still men of good character, and they no doubt persuaded themselves that, since the income of these estates was needed for the fulfilment of their spiritual task, it was proper to defend them by the sword. But casuistry of this kind has never prospered indefinitely, and few historians will doubt that this temporal development led directly to that degradation of the Papacy which rendered it unfit to exercise moral influence on Europe. The Papacy became a princedom to attract the covetous and the ambitious, and the line of Popes sank so low by the tenth century that the grossest characters were able to occupy the chair of Peter at a time when the nations of Europe were sufficiently advanced to be susceptible of a sincere moral influence. The record of the Papacy, from the ninth century to the nineteenth, contains on almost every page a bloody struggle for the temporal power.
