In the midst of the rejoicings that heralded his birth news came to Valladolid that the emperor’s Spanish and German troops had assaulted and sacked Rome, and that Pope Clement VII. was surrounded by infuriated soldiery, a prisoner in his own castle of St. Angelo. In the long rivalry which Charles had sustained with the French king, Francis I., who had competed with him for the imperial crown, one of the main factors was the dread of the entire domination of Italy by Spain, by virtue of the suzerainty of the empire over the country. The excitable and unstable pontiff, Clement VII., thought that his own interests were threatened, and made common cause with Francis. The emperor’s troops were commanded by Charles de Montpensier, Duke of Bourbon, who had quarrelled with his own sovereign, and was in arms against him, and he unquestionably exceeded the emperor’s wishes in the capture and sacking of the eternal city, the intention having been to have held the pontiff in check by terror rather than to degrade him in the eyes of the world. Charles made what amends he could for the blunder committed by Bourbon, and at once suspended the rejoicings for the birth of his heir. But the gossips in Valladolid gravely shook their heads, and prophesied that the great emperor’s first-born was destined to be a bane to the papacy in years to come. It will be seen in the course of the present book that during the whole of his life Philip regarded the papacy and the persons of the pontiffs without any superstitious awe, and mainly as instruments in his hands to achieve the great work entrusted to him by Providence.
