Władysław II Jagiellończyk

Vladislaus II, also known as Vladislav, Władysław, or Wladislas ;, was King of Bohemia from 1471 to 1516 and King of Hungary and King of Croatia from 1490 to 1516. As the eldest son of Casimir IV Jagiellon, he was expected to inherit the Crown Kingdom of Poland and adjacent Grand Duchy of Lithuania. George of Poděbrady, the Hussite ruler of Bohemia, offered to make Vladislaus his heir in 1468. George needed Casimir's support against the rebellious Roman Catholic noblemen and their ally King of Hungary Matthias Corvinus. The Diet of Bohemia elected Vladislaus king after George's death, but he could rule only Bohemia proper because Matthias, whom the Roman Catholic nobles had elected king, occupied adjacent Moravia, and further east of Silesia in southeastern Germany and both Lusatias. Vladislaus tried to reconquer the four provinces with his father's assistance but was repelled by Matthias.
