Dubravka. Boleslav III was obliged to fly from Bohemia, and after wandering through Germany at last sought refuge with his former enemy, Boleslav the Brave of Poland. In the meantime Vladivoj, finding that the dynasty of Přemysl, whose claims in consequence of the crimes of Boleslav III now reverted to his brothers Jaromir and Ulrich, had still many adherents, endeavoured to strengthen his hold on Bohemia by German aid.
He therefore appeared at the court of the German King Henry II at Regensburg, and not only consented to the payment of the tribute which had already been extorted from several Bohemian princes, but also became a vassal of the German monarch under the (German) title of duke.
