As soon as Bruno of Olmütz heard of this loss, he advised Ottakar to yield. Ottakar was most reluctant that the struggle should end without a pitched battle; but another enemy now threatened to appear on the scene. Ladislaus, the new king of Hungary, was smarting under the recollection of the defeats which his predecessor had sustained; and he prepared to invade Bohemia. This new danger seems to have decided Ottakar to yield. He therefore publicly surrendered to Rudolf all his claims on Austria, Styria, Carinthia, and Carniola, and did homage to him as Emperor for his kingdom of Bohemia and Moravia. Such a settlement could not possibly be lasting. Ottakar had not yet been defeated in any pitched battle; his wife Kunigunda is said to have reproached him for his weakness in yielding so soon; and, in the carrying out of the treaty which followed, numerous questions, of doubtful interpretation, quickly came to the front. In this case, one of Rudolf’s otherwise successful daughters proved a source of contention rather than of unity. Guta, the daughter whom Rudolf had offered as a bride to Ottakar’s son, had been promised large lands as her dowry; and Ottakar maintained that, as these lands must necessarily lie in Austria, he was not bound to evacuate those territories, but should rather claim them as his due. Rudolf, on the other hand, insisted that the terms of the treaty involved the evacuation of the whole of Austria.
A question which must have touched Ottakar far more nearly was the interpretation of the clause about the extension to the supporters of each King of all the securities gained by the peace. The discontent of the nobles with Ottakar’s rule had extended even to Bohemia and Moravia; and many of the king’s native subjects had entered into intrigues with Rudolf. Rudolf maintained that, as these men must be considered his supporters, they were entitled to the same concessions as the other champions of his cause. It was obvious that such grounds of division as these, by whatever compromise they might be settled at the moment, must leave a lasting sting behind them; and there is no sign in the letters of either King of even such a pretence of friendship, as the ordinary exigencies of diplomacy might seem to require. Both Rudolf and Ottakar were, in fact, preparing for a new struggle, and looking about for allies.
