The king of Navarre declared himself a Protestant, and the spirit of the Reformation, as we have related, had also secretly spread into Spain. But there already the terrible Inquisition, with Philip II. at its head, had crushed out Protestantism from Spain. It was not to be expected that Philip, having exterminated heresy in one part of his dominions, would tolerate its existence in any other, least of all in so important a country as the Netherlands. So the persecutions commenced there. During the latter part of the fifteenth century, and the beginning of the sixteenth, the pontifical throne had been filled by a succession of popes, notorious for their religious indifference, and the carelessness and profligacy of their lives. This was one of the prominent causes of the Reformation. But before the close of the sixteenth century, a line of popes had arisen, of stern and austere natures, without a touch of sympathy for the joys and sorrows of mankind, and entirely devoted to the work of regaining the lost powers of the Roman Catholic Church. Pope Pius the Fifth was such a pontiff. He wrote to Philip, urging him not to falter in the good cause, and to allow no harm to the Catholic faith, but to march against his rebellious vassals at the head of his army, and wash out the stain of heresy in the blood of the heretic. To him Philip replied: that the Pope might rest assured that the king would consent to nothing that could prejudice the service of God, or the interests of religion. He deprecated force, as that would involve the ruin of the country. Still he would march in person, without regard to his own peril, and employ force, though it should cost the ruin of the provinces; but he would bring his vassals to submission. “For he would sooner lose a hundred lives, and every rood of empire, than reign a lord over heretics.” With such a pope, and such a king, no wonder that the Inquisition flourished. The situation of the Netherlands was such that the various opinions of the surrounding nations were easily transferred to their shores. On the south were the Lutherans of Germany; on the west, the French Huguenots; while by the ocean, they held communication with England and the nations of the Baltic. The soldier quartered on their territory, the seaman who visited their shores, the trader who trafficked in their towns, brought with them different forms of the “_New Religion_.” As most of the people were able to read, books from France and Germany were circulated amongst them. Philip II. understood the importance of his position. His whole life proves that he felt it to be his especial mission to restore the tottering fortunes of Catholicism, and stay the torrent which was sweeping away the Roman Catholic faith. Philip had made his half-sister, Margaret, regent in the Netherlands.
