Vladislav himself is said to have killed Dacio, one of the leaders of the Milanese, on the occasion of a sortie. After the capitulation of Milan, Vladislav II returned to his country, and arrived at Prague towards the end of the year 1158.
Not long after this (1164) Vladislav became involved in a war that had broken out in Hungary, between two rival claimants to that throne. In this war also Vladislav II was victorious; and he succeeded in establishing Stephen III, who had invoked his aid, on the throne, though the rival claimant had obtained aid from the Greek Emperor.
In 1173 Vladislav, tired out by his many wars, and perhaps still more by the internal dissensions which still continued, abdicated in favour of his eldest son Frederick, and retired to the monastery of Strahow near Prague.
The years following the abdication of Vladislav are noticeable because of the uninterrupted struggle for supremacy between numerous members of the dynasty of Přemysl, in twenty-four years no less than ten changes occurring in the person of the sovereign. As Palacký himself tells us that the genealogy of the family of Přemysl at this period is very obscure, it could be of no interest to attempt to decide the legitimacy of the claims of the various pretenders, or to give a detailed account of the feuds which ensued. It is of more interest to note that in consequence of these civil wars, the authority of Germany over Bohemia became far greater than before.
Frederick was, almost immediately after his accession, driven from the throne by Soběslav (II), one of his rivals (1174). Soběslav maintained himself for some time with the aid of Frederick Barbarossa, who recognized him as Prince of Bohemia, though he decreed that the title of king should no longer be borne by the rulers of that country. The German Emperor, however, soon changed sides. Encouraged by him, Frederick returned to Bohemia (1178), and waged war against Soběslav up to the time of the latter's death (1180). Frederick, unfortunately, soon found a new rival in Conrad of Znoymo, also a prince of the Přemysl dynasty. Frederick was again obliged to fly from Bohemia; and the Emperor Frederick Barbarossa now summoned Conrad and the Bohemian nobles who adhered to him, to appear at the Imperial court at Regensburg, as he claimed the right to settle the dissensions in Bohemia.
