Maximilian's reputation in the Empire was now perhaps higher than it had ever been before; the more so, that in the winter of 1504 death had removed his old opponent, Berthold of Mainz, and that the new Elector was a near relative of his own.[68] But when the future was all bright with hope, and when his coronation at Rome and an union of Spain and the Empire against the French and the Turks seemed at last on the point of realization, his golden dreams met with a rude awakening. The sudden and premature death of Philip, who had assumed in person the government of Castile, and was successfully defending himself against the spiteful intrigues of Ferdinand, put an end to the Emperor's projects of Hapsburg combination (Sep. 25, 1506). The Catholic King recovered the Regency, and was soon more powerful than ever in the Spanish Peninsula. Maximilian at first met with no better success in his attempt to { 54} secure the government of the Low Countries. The Estates of the seventeen Provinces refused to recognize his claims to the Regency during the minority of his grandson Charles, and were encouraged by Louis XII. in the formation of a Council of Regency. But internal troubles, and the activity of Charles of Gueldres, pled his cause more eloquently than any measures of his own. On their voluntary submission to his rule, he appointed William de Croy, Lord of Chièvres, and Adrian of Utrecht[69] as Charles' tutors, and entrusted the administration to his daughter Margaret, the widowed Duchess of Savoy, who made her public entry into Mechlin in July 1507, and who throughout her rule justified his choice by her scrupulous integrity and brilliant statesmanship.
In the same year, 1507, Maximilian made a fiery appeal to the Diet assembled at Constance, for assistance in his schemes of a journey to Rome and the expulsion of the French from Milan. After considerable delay he obtained a grant of 3,000 horse and 9,000 foot for six months, and received a further promise of 6,000 men from the Swiss envoys. But his sanguine expectations were once more doomed to disappointment. The majority of the promised troops never made their appearance; French gold won over his Swiss allies;[70] and the Estates of his own dominions outdid all previous occasions in their parsimony. Meanwhile his ardent preparations had roused the distrust of Venice, which refused him passage through { 55} her dominions, unless he restricted himself to a trifling escort. His army was too weak to force its way either through Milanese or through Venetian territory; and hence he was driven to an expedient which involved a break with the old mediaeval traditions of the Empire. On February 4, 1508, he had himself proclaimed with great pomp and solemnity, in the Cathedral of Trent, as Holy Roman Emperor. It was declared that for the future in all official documents he should be known by the title of "erwählte römischer Kaiser," but that for convenience sake he should commonly be called "Emperor." Julius II. raised no objection, partly because Maximilian fully acknowledged the Papal right to crown him, and still more because his arrival in Rome with an army would have been a most unwelcome event. Maximilian's step was the first departure from the immemorial custom of his predecessors; but with the exception of his grandson, Charles V., not one of his successors in the Empire received his crown at the hands of the Pope.
