“ In 1446 Hunyadi, now governor of Hungary, harried the Cilli territories in Croatia-Slavonia; but his power was broken at Kossovo (1448) , and Count Ulrich was able to lead a successful crusade, nominally in the Habsburg interest, into Hungary (1450) . In 1452 he forced the emperor Frederick III. to hand over the boy king Ladislaus V. to his keeping, and became thus practically ruler of Hungary. In 1454 his power was increased by his succession to his father’s vast wealth; and in 1456 he was named by Ladislaus his lieutenant in Hungary. The Hunyadis now conspired to destroy him. ”

“ His influence in the troubled affairs of Hungary and the Empire early overshadowed that of his father, together with whom he was made a prince of the Empire by the emperor Sigismund (1436) . Hence feuds with the Habsburgs, wounded in their rights as overlords of Cilli, ending, however, in an alliance with the Habsburg king Albert II., who made Ulrich for a short while his lieutenant in Bohemia. ”
