Philip knew well that force alone was insufficient to reduce such a people to slavery. He succeeded in persuading the states to grant him considerable subsidies, some of which were to be paid by instalments during a period of nine years. That was gaining a great step toward his designs, as it superseded the necessity of a yearly application to the three orders, the guardians of the public liberty. At the same time he sent secret agents to Rome, to obtain the approbation of the pope to his insidious but most effective plan for placing the whole of the clergy in dependence upon the crown. He also kept up the army of Spaniards and Germans which his father had formed on the frontiers of France; and although he did not remove from their employments the functionaries already in place, he took care to make no new appointments to office among the natives of the Netherlands. In the midst of these cunning preparations for tyranny, Philip was suddenly attacked in two quarters at once; by Henry II. of France, and by Pope Paul IV. A prince less obstinate than Philip would in such circumstances have renounced, or at least postponed, his designs against the liberties of so important a part of his dominions, as those to which he was obliged to have recourse for aid in support of this double war. But he seemed to make every foreign consideration subservient to the object of domestic aggression which he had so much at heart. He, however, promptly met the threatened dangers from abroad. He turned his first attention toward his contest with the pope; and he extricated himself from it with an adroitness that proved the whole force and cunning of his character. Having first publicly obtained the opinion of several doctors of theology, that he was justified in taking arms against the pontiff (a point on which there was really no doubt), he prosecuted the war with the utmost vigor, by the means of the afterward notorious duke of Alva, at that time viceroy of his Italian dominions. Paul soon yielded to superior skill and force, and demanded terms of peace, which were granted with a readiness and seeming liberality that astonished no one more than the defeated pontiff. But Philip's moderation to his enemy was far outdone by his perfidy to his allies. He confirmed Alva's consent to the confiscation of the domains of the noble Romans who had espoused his cause; and thus gained a stanch and powerful supporter to all his future projects in the religious authority of the successor of St. Peter.
