called himself Vilém of Pernštejn and Helfštejn. After the cease-fire of Breslau of 1474, Corvinus appointed Vilém High Treasurer of Moravia. Vilém's father died in 1475. His possessions were inherited by Vilém and his brothers Jan (d. 1478 or 1480), Vratislav I (d. 1496) and Jimram (d. 1481 or 1482). As his brothers were still minors, Vilém took up guardianship and overall management of the possessions. Eliška of Boskovice, the widow of his elder brother Sigmund, and her daughters, only inherited money. Vilém acquired extensive estates in Bohemia through his marriage with Johanka of Liblice; he sold these shortly after the wedding. His father's inheritance was divided in 1478, when his brothers Jan and Vratislav came of age. Jan and Vratislav jointly received Pernštejn Castle and some of the surrounding villages. Vilém kept Zubštejn Castle and the remaining villages in the Pernštejn area for himself and his youngest brother Emmeran, who was still a minor. The elder brothers also inherited the debt their father had left behind, for which Vilém had vouched. He had bought, and paid, on behalf of his father, the Lordship of Meziříčí from his father in law, Jan of Lomnice. When Jan died in 1478 (or 1480), Vratislav inherited his share of the inheritance. The youngest brother, Jimram, died in 1481 or 1482 and Vilém inherited his share. The Bohemian-Hungarian war ended in 1479 with the Treaty of Olomouc. In 1480, Vilém campaigned to have the entries in the Moravian Landtafel written in Czech rather than Latin. In 1482, Vilém's confidant Pertold of Lipá died. In is testament, he had named Vilém as the guardian of his two children. In this capacity, Vilém took up the regency of Lipá's extensive estates around Moravský Krumlov. He moved his residence to Krumlov, which was also closer to the Hungarian royal court in Budapest. Although Vilém had already been married for several years, all his children would be born in Krumlov. Vilém soon arranged marriages for Lípa's children. According to an agreement made in 1484, Barbora Lípa was to marry Wolfgang of Liechtenstein, a son of Christopher of Liechtenstein. Vilém's daughter Bohunka, who was only born in 1485, was to marry Jindřich of Lipá, who was also under Vilém's guardianship. Already in 1483, Vilém had arranged a marriage between Eliška of Kravaře, Lípa's widow, and Peter IV of Rosenberg. As part of the guardianship, Vilém had become High Marshall
