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.
