All this vast empire, with its magnificent resources, was placed at the disposal of a single man. Philip ruled over it with an authority more absolute than that possessed by any European prince since the days of the Cæsars. The Netherlands, indeed, maintained a show of independence under the shadow of their ancient institutions. But they consented to supply the necessities of the crown by a tax larger than the revenues of America. Naples and Milan were ruled by Spanish viceroys. Viceroys, with delegated powers scarcely less than those of their sovereign, presided over the American colonies, which received their laws from the parent country. In Spain itself, the authority of the nobles was gone. First assailed under Ferdinand and Isabella, it was completely broken down under Charles the Fifth. The liberties of the commons were crushed at the fatal battle of Villalar, in the beginning of that monarch's reign. Without nobles, without commons, the ancient cortes had faded into a mere legislative pageant, with hardly any other right than that of presenting petitions, and of occasionally raising an ineffectual note of remonstrance against abuses. It had lost the power to redress them. Thus all authority vested in the sovereign. His will was the law of the land. From his palace at Madrid he sent forth the edicts which became the law of Spain and of her remotest colonies. It may well be believed that foreign nations watched with interest the first movements of a prince who seemed to hold in his hands the destinies of Europe; and that they regarded with no little apprehension the growth of that colossal power which had already risen to a height that cast a shadow over every other monarchy.
From his position, Philip stood at the head of the Roman Catholic princes. He was in temporal matters what the pope was in spiritual. In the existing state of Christendom, he had the same interest as the pope in putting down that spirit of religious reform which had begun to show itself, in public or in private, in every corner of Europe. He was the natural ally of the pope. He understood this well, and would have acted on it. Yet, strange to say, his very first war, after his accession, was with the pope himself. It was a war not of Philip's seeking.
