imperial hands. It was arranged that Charles' only daughter and heiress
should be betrothed to Maximilian of Austria, the emperor's eldest son,
and the very day and hour for the coronation were fixed. But the
Burgundian had an enemy in Louis XI of France, who was as prudent and
far-seeing as his rival was rash and impetuous, and who was far more
than his match in political craft and cunning. French secret agents
stirred up Frederick's suspicions against Charles' designs, and the
emperor suddenly left Trier, where he had felt humiliated by the
splendour of his powerful vassal.

The duke was furious at his disappointment, but was only the more
obstinately bent on carrying out his plans. But Louis had been meanwhile
forming a strong league (League of Constance, March 1474) of various
states threatened by Charles' ambitious projects. Duke Sigismund of
Austria, Baden, Basel, Elsass, and the Swiss Cantons united under the
leadership of France to resist them. Charles led an army of 60,000 men
to aid the Archbishop of Cologne against his subjects, but spent eleven
months in a fruitless attempt to take a small fortified town, Neuss, in
which a considerable portion of his army perished. He was compelled to
raise large sums of money from his unwilling subjects in the Netherlands
to repair his losses, and in 1475 he attacked Duke Réné of Lorraine,
captured Nancy and conquered the duchy, which had hitherto separated his
Netherland from his French possessions. It was the first step in the
accomplishment of his scheme for the restoration of the Lotharingian
kingdom. In Elsass, however, the populace had risen in insurrection
against the tyranny of the Burgundian governor, Peter van Hagenbach, and
had tried and executed him. Finding that the Swiss had aided the rebels,
Charles now, without waiting to consolidate his conquest of Lorraine,
determined to lead his army into Switzerland. At the head of a
splendidly equipped force he encountered the Confederates near Granson
