While the emperor was in this melancholy state, his insane mother, who had lingered for years in delirious gloom, died on the 4th of April, 1555.  It will be remembered that Charles had inherited valuable estates in the Low Countries from his marriage with the daughter of the Duke of Burgundy.  Having resolved to abdicate all his power and titles in favor of his son, he convened the States of the Low Countries at Brussels on the 25th of October, 1555.  Charles was then but fifty-five years of age, and should have been in the strength of vigorous manhood.  But he was prematurely old, worn down with care, toil and disappointment.  He attended the assembly accompanied by his son Philip.  Tottering beneath infirmities, he leaned upon the shoulders of a friend for support, and addressed the assembly in a long and somewhat boastful speech, enumerating all the acts of his administration, his endeavors, his long and weary journeys, his sleepless care, his wars, and, above all, his victories.  In conclusion he said: 

“While my health enabled me to perform my duty, I cheerfully bore the burden; but as my constitution is now broken by an incurable distemper, and my infirmities admonish me to retire, the happiness of my people affects me more than the ambition of reigning.  Instead of a decrepid old man, tottering on the brink of the grave, I transfer your allegiance to a sovereign in the prime of life, vigilant, sagacious, active and enterprising.  With respect to myself, if I have committed any error in the course of a long administration, forgive and impute it to my weakness, not to my intention.  I shall ever retain a grateful sense of your fidelity and attachment, and your welfare shall be the great object of my prayers to Almighty God, to whom I now consecrate the remainder of my days.”

Then turning to his son Philip, he said: 

“And you, my son, let the grateful recollection of this day redouble your care and affection for your people.  Other sovereigns may rejoice in having given birth to their sons and in leaving their States to them after their death.  But I am anxious to enjoy, during my life, the double satisfaction of feeling that you are indebted to me both for your birth and power.  Few monarchs will follow my example, and in the lapse of ages I have scarcely found one whom I myself would imitate.  The resolution, therefore, which I have taken, and which I now carry into execution, will be justified only by your proving yourself worthy of it.  And you will alone render yourself worthy of the extraordinary confidence which I now repose in you by a zealous protection of your religion, and by maintaining the purity of the Catholic faith, and by governing with justice and moderation.  And may you, if ever you are desirous of retiring like myself to the tranquillity of private life, enjoy the inexpressible happiness of having such a son, that you may resign your crown to him with the same satisfaction as I now deliver mine to you.”
