In consideration of the peaceable abandonment by the House of Hapsburg of its immediate claims, it was promised the succession to the throne of Bohemia as soon as the direct lines of Charles and of his brother John should have come to an end. In all these matters Charles had shown a genuine desire for peace and order, which must surely deserve all recognition. The same credit cannot be given to another phase of his policy, which arose from his relations with Louis, the son of his former rival, the Emperor Louis of Bavaria. The causes of this quarrel must be shortly told. John, the brother of Charles, had married Margaretha Maultasche, Countess of Tyrol; and he had thereby acquired her lands. Margaretha, who seems to have been as foul in mind as she was ugly in face, made a false charge of impotency against her husband; and, under this excuse, she hastened to welcome the advances of young Louis, the son of the Emperor, who helped her to drive her husband from the Tyrol. The Emperor recognised a so-called marriage between his son and Margaretha; and this act contributed not a little to the storm of indignation which drove the Bavarian from the throne of the Empire and raised Charles to his place. Charles was scarcely seated on the throne, before he resolved to revenge his brother by a raid on the Tyrol. The raid produced no results but bloodshed and misery; and John was forced to console himself for the loss of his lands by the Margravate of Moravia, and for the loss of Margaretha by marriage with a more faithful wife.
