when Charles (1543) in effect severed the Netherlands from the Empire and transferred them to Spain. He sacrificed German interests in Holstein to those of his brother-in-law Christian II of Denmark; and, although he was not primarily responsible for the loss of Metz, Toul, and Verdun in 1552, his neglect of German interests along the Slavonic coasts of the Baltic was not without effect upon the eventual incorporation of Esthonia, Livonia, and Courland, in the Russian domains of the Czar. German troops had been wont to march on Rome; but Charles brought Italian troops to the banks of the Elbe. He introduced into Germany that Spanish taint which was only washed out in the Thirty Years' War; and he then sought to turn that tide of northern influence, which has been flowing ever since the decline of the Roman Empire.
In religion as well as in politics Charles' increasingly Spanish tendencies had an evil effect on the Empire. He was no theologian, and he could never comprehend the Reformers' objections to Roman dogma; but that did not make him less hostile to their cause. His attitude towards religion was half way between the genial orthodoxy of his grandfather Maximilian and the gloomy fanaticism of his son Philip II, but his mind was always travelling away from the former and towards the latter position; and the transition enhanced the difficulty of coming to an accommodation with Lutheran heretics.
This orthodoxy, however, implied no blindness to the abuses of the Pope's temporal power, and was always conditioned by regard for the Emperor's material interests. The fervid declaration of zeal against Luther which Charles read at the Diet of Worms has been described as the most genuine expression of his religious feelings. No doubt it was sincere, but it is well to note that the Emperor's main desire was then to wean Leo X from his alliance with Francis I, and to prove to the papal Nuncio that, whatever the Diet might do, Charles' heart was in the right place. If he often assumed the rôle of papal champion, he could on occasion remember that he was the successor of Henry IV, and to some at least the Sack of Rome must have seemed a revenge for the scene at Canossa. He could tell Clement that that outrage was the just judgment of God, he could seize the temporalities of the bishopric of Utrecht, and speak disrespectfully of papal excommunications. He could discuss proposals for deposing the Pone and destroying his temporal power, and was even tempted to think that Luther might one day become of importance if Clement continued to thwart the imperial plans.
With Charles, as with every prince of the age, including the Pope, political far outweighed religious motives. Chivalry and the crusading spirit were both dead. His religious faith and family pride might both have impelled him to avenge upon Henry VIII the wrongs of Catharine of Aragon; but these, he said, were private griefs; they must not be allowed to interfere with the public considerations which compelled him
