[Sidenote: EMPIRE OF PHILIP] CHAPTER V. WAR WITH THE POPE. Empire of Philip.--Paul the Fourth.--Court of France.--League against Spain.--The Duke of Alva.--Preparations for War.--Victorious Campaign. 1555, 1556. Soon after Philip's arrival in Brussels took place that memorable scene of the abdication of Charles the Fifth, which occupies the introductory pages of our narrative. By this event, Philip saw himself master of the most widely extended and powerful monarchy in Europe. He was king of Spain, comprehending under that name Castile, Aragon, and Granada, which, after surviving as independent states for centuries, had been first brought under one sceptre in the reign of his father, Charles the Fifth. He was king of Naples and Sicily, and duke of Milan, which important possessions enabled him to control, to a great extent, the nicely balanced scales of Italian politics. He was lord of Franche Comté, and of the Low Countries, comprehending the most flourishing and populous provinces in Christendom, whose people had made the greatest progress in commerce, husbandry, and the various mechanic arts. As titular king of England, he eventually obtained an influence, which, as we shall see, enabled him to direct the counsels of that country to his own purposes. In Africa he possessed the Cape de Verd Islands and the Canaries, as well as Tunis, Oran, and some other important places on the Barbary coast. He owned the Philippines and the Spice Islands in Asia. In America, besides his possessions in the West Indies, he was master of the rich empires of Mexico and Peru, and claimed a right to a boundless extent of country, that offered an inexhaustible field to the cupidity and enterprise of the Spanish adventurer. Thus the dominions of Philip stretched over every quarter of the globe. The flag of Castile was seen in the remotest latitudes,--on the Atlantic, the Pacific, and the far-off Indian seas,--passing from port to port, and uniting by commercial intercourse the widely scattered members of her vast colonial empire.
