On the 23rd of January, 1569, the Archduke presented the King with a spirited reply to the public letter. It was couched in the spirit of the instructions, and therefore need not be analysed at length. He did not believe that his Imperial Majesty would admit any justification of the course pursued in the Netherlands. The estates of the Empire would never allow Philip's reasoning concerning the connexion of those countries with the Empire, nor that they were independent, except in the particular articles expressed in the treaty of Augsburg. In 1555, when Charles the Fifth and King Ferdinand had settled the religious peace, they had been assisted by envoys from the Netherlands. The princes of the Empire held the ground, therefore, that the religious peace, which alone had saved a vestige of Romanism in Germany, should of right extend to the provinces. As to the Prince of Orange, the Archduke would have preferred to say nothing more, but the orders of the Emperor did not allow him to be silent. It was now necessary to put an end to this state of things in Lower Germany. The princes of the Empire were becoming exasperated. He recalled the dangers of the Smalcaldian war—the imminent peril in which the Emperor had been placed by the act of a single elector. They who believed that Flanders could be governed in the same manner as Italy and Spain were greatly mistaken, and Charles the Fifth had always recognised that error.
This was the sum and substance of the Archduke's mission to Madrid, so far as its immediate objects were concerned. In the course, however, of the interview between this personage and Philip, the King took occasion to administer a rebuke to his Imperial Majesty for his general negligence in religious matters. It was a matter which lay at his heart, he said, that the Emperor, although, as he doubted not, a Christian and Catholic prince, was from policy unaccustomed to make those exterior demonstrations which matters of faith required. He therefore begged the Archduke to urge this matter upon the attention of his Imperial Majesty.
The Emperor, despite this solemn mission, had become more than indifferent before his envoy had reached Madrid. For this indifference there were more reasons than one. When the instructions had been drawn up, the death of the Queen of Spain had not been known in Vienna. The Archduke had even been charged to inform Philip of the approaching marriages of the two Archduchesses, that of Anne with the King of France, and that of Isabella with the King of Portugal. A few days later, however, the envoy received letters from the Emperor, authorizing him to offer to the bereaved Philip the hand of the Archduchess Anne.
[Herrera (lib. xv. 707) erroneously states that the Archduke was, at the outset, charged with these two commissions by the Emperor; namely, to negotiate the marriage of the Archduchess Anne with Philip, and to arrange the affairs of the Netherlands. On the contrary, he was empowered to offer Anne to the King of France, and had already imparted his instructions to that effect to Philip, before he received letters from Vienna, written after the death of Isabella had become known. At another interview, he presented this new matrimonial proposition to Philip. These facts are important, for they indicate how completely the objects of the embassy, the commencement of which was so pretentious, were cast aside, that a more advantageous marriage for one of the seven Austrian Archduchesses might be secured.—Compare Correspondance de Philippe]
The King replied to the Archduke, when this proposition was made, that if he had regard only to his personal satisfaction, he should remain as he was. As however he had now no son, he was glad that the proposition had been made, and would see how the affair could be arranged with France.
Thus the ill success of Orange in Brabant, so disheartening to the German princes most inclined to his cause, and still more the widowhood of Philip, had brought a change over the views of Maximilian. On the 17th of January, 1569, three days before his ambassador had entered upon his negotiations, he had accordingly addressed an autograph letter to his Catholic Majesty. In this epistle, by a few, cold lines, he entirely annihilated any possible effect which might have been produced by the apparent earnestness of his interposition in favor of the Netherlands. He informed the King that the Archduke had been sent, not to vex him, but to convince him of his friendship. He assured Philip that he should be satisfied with his response, whatever it might be. He entreated only that it might be drawn up in such terms that the princes and electors to whom it must be shown, might not be inspired with suspicion.
The Archduke left Madrid on the 4th of March, 1569. He retired, well pleased with the results of his mission, not because its ostensible objects had been accomplished, for those had signally failed, but because the King had made him a present of one hundred thousand ducats, and had promised to espouse the Archduchess Anne. On the 26th of May, 1569, the Emperor addressed a final reply to Philip, in which he expressly approved the King's justification of his conduct. It was founded, he thought, in reason and equity. Nevertheless, it could hardly be shown, as it was, to the princes and electors, and he had therefore modified many points which he thought might prove offensive.
Thus ended "in smoke," as Granvelle had foretold, the famous mission of Archduke Charles. The Holy Roman Emperor withdrew from his pompous intervention, abashed by a rebuke, but consoled by a promise. If it were good to be guardian of religious freedom in Upper and Nether Germany, it was better to be father-in-law to the King of Spain and both the Indies. Hence the lame and abrupt conclusion.
Cardinal Granvelle had been very serviceable in this juncture. He had written to Philip to assure him that, in his, opinion, the Netherlands had no claim, under the transaction of Augsburg, to require the observance within their territory of the decrees of the Empire. He added, that Charles the Fifth had only agreed to the treaty of Passau to save his brother Ferdinand from ruin; that he had only consented to it as Emperor, and had neither directly nor indirectly included the Netherlands within its provisions. He stated, moreover, that the Emperor had revoked the treaty by an act which was never published, in consequence of the earnest solicitations of Ferdinand.
It has been seen that the King had used this opinion of Granvelle in the response presented to the Archduke. Although he did not condescend to an argument, he had laid down the fact as if it were indisputable. He was still more delighted to find that Charles had revoked the treaty of Passau, and eagerly wrote to Granvelle to inquire where the secret instrument was to be found. The Cardinal replied that it was probably among his papers at Brussels, but that he doubted whether it would be possible to find it in his absence. Whether such a document ever existed, it is difficult to say. To perpetrate such a fraud would have been worthy of Charles; to fable its perpetration not unworthy of the Cardinal. In either case, the transaction was sufficiently high-handed and exceedingly disgraceful.
