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.
