Up to this time, the German Empire had always claimed that its jurisdiction extended over Switzerland, but henceforth no effort was ever made to enforce it. The little communities of free people, who had defied and humiliated Austria, and now, within a few months, crushed the splendid and haughty house of Burgundy, were left alone, an eye-sore to the neighboring princes, but a hope to their people. The Hapsburg dynasty, nevertheless, profited by the fall of Charles the Bold. Mary of Burgundy gave her hand to Maximilian, in 1477, and he established his court in Flanders. He was both handsome and intellectually endowed, and was reputed to be the most accomplished knight of his day. Louis XI. of France attempted to gain possession of those provinces of Burgundy which had French population, but was signally defeated by Maximilian in 1479. Three years afterwards, however, when Mary of Burgundy was killed by a fall from her horse, the cities of Bruges and Ghent, instigated by France, claimed the guardianship of her two children, Philip and Margaret, the latter of whom was sent to Paris to be educated as the bride of the Dauphin. A war ensued which lasted until 1485, when Maximilian was reluctantly accepted as Regent of Flanders. [Sidenote: 1485.] While these events were taking place, Frederick III. was involved in a quarrel with Matthias Corvinus, king of Hungary, who easily succeeded in driving him from Vienna, and then from Austria. Still the German princes looked carelessly on, and the weak old Emperor wandered from one to the other, everywhere received as an unwelcome guest. In 1486 he called a Diet at Frankfort, and endeavored, but in vain, to procure a union of the forces of the Empire against Hungary. All that was accomplished was Maximilian's election as King of Germany. Immediately after being crowned at Aix-la-Chapelle, he made a formal demand on Matthias Corvinus for the surrender of Austria. Before any further steps could be taken, he was recalled to Flanders by a new rebellion, which lasted for three years. Frederick III., deserted on all sides, and seeing the Hapsburg possessions along the frontiers of Austria and Tyrol threatened by Bavaria, finally appealed to the Suabian cities for help. He succeeded in establishing a new Suabian League, which was composed of twenty-two free cities, the Count of Würtemberg and a number of independent nobles. A force was raised, with which he first marched to the relief of Maximilian, who had been taken and imprisoned at Bruges and was threatened with death. The undertaking was successful: Maximilian was released, and in 1489 his authority was established over all the Netherlands.
