he grave,
too, of Queen Isabella arose the most importunate phantom in his path.
The King of Spain was a widower again, and the Emperor among his sixteen
children had more than one marriageable daughter. To the titles of
"beloved cousin and brother-in-law," with which Philip had always been
greeted in the Imperial proclamations, the nearer and dearer one of
son-in-law was prospectively added.

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

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.

Accordingly, on the 21st October, 1568, the Emperor presented his brother
with an ample letter of instructi
