The ties of wedlock were sacred in the traditions of the Habsburg house, but still the intervention was nominally made. As early as August, 1568, the Emperor's minister at Madrid had addressed a memorial to the King. He had spoken in warm and strong language of the fate of Egmont and Horn, and had reminded Philip that the executions which were constantly taking place in the provinces were steadily advancing the Prince of Orange's cause. On the 22nd September, 1568, the six electors had addressed a formal memorial to the Emperor. They thanked him for his previous interposition in favor of the Netherlands, painted in lively colors the cruelty of Alva, and denounced the unheard-of rigor with which he had massacred, not only many illustrious seigniors, but people of every degree. Notwithstanding the repeated assurances given by the King to the contrary, they reminded the Emperor, that the inquisition, as well as the Council of Trent, had now been established in the Netherlands in full vigor. They maintained that the provinces had been excluded from the Augsburg religious peace, to which their claim was perfect. Nether Germany was entitled to the same privileges as Upper Germany. They begged the Emperor to make manifest his sentiments and their own. It was fitting that his Catholic Majesty should be aware that the princes of the Empire were united for the conservation of fatherland and of tranquillity. To this end they placed in the Emperor's hands their estates, their fortunes, and their lives. Such was the language of that important appeal to the Emperor in behalf of oppressed millions in the Netherlands, an appeal which Granvelle had coldly characterized as an intrigue contrived by Orange to bring about his own restoration to favor! The Emperor, in answer, assured the electoral envoys that he had taken the affair to heart, and had resolved to despatch his own brother, the Archduke Charles, on a special mission to Spain.
