Maximilian, notwithstanding this triumph of his diplomacy, met with the utmost difficulty in raising money for his operations against the French; while a new enemy had arisen in the young Charles of Egmont, who had recently recovered the Duchy of Gueldres, and who was destined to be a thorn in Maximilian's side for the rest of the reign. Though his position in West Germany was strengthened by a League with the "Lower Union,"[40] the sole result of his efforts at the Diet of Coblenz was a prospective grant of 94,000 gulden, of which only 16,000 actually came in. His campaign against the French has already been sketched (p. 25). Scarcely were his {33} hands freed by the Peace of Senlis, when an incursion of the Turks into Styria (August 1493) made a fresh demand upon his attention. Then, as usual, the necessary aid arrived too late, and the marauders returned home almost unchallenged. In the midst of this danger Frederick III., whose health had been failing for some time, and whose foot it had been found necessary to amputate,[41] died at Linz, in the seventy-eighth year of his age (August 19, 1493). The old Emperor had lived to see his dreams of Hapsburg revival and consolidation to a great extent realized; but his irritable nature had led him to thwart the family aspirations on Hungary. In his dread lest the acquisition of a throne should make his son more powerful than himself, he afforded him no assistance, nay rather, threw every hindrance in his way. Frederick's death was an undoubted gain to Maximilian, for it left him Emperor elect and unquestioned ruler of the Hapsburg dominions. Family divisions were no longer possible, since no relative capable of resistance survived.[42]
