Wenceslaus IV of Bohemia
Wenceslaus died in Luxembourg, leaving Joanna as sole ruler of Brabant, and was succeeded by Wenceslaus II (Wenceslaus IV of Bohemia) as duke of Luxembourg. There are speculations that he might have died of leprosy. His last wish was his heart to be displaced from his dead body and sent to his wife (Joanna stayed in Brussels). He is buried in a crypt at the now-ruined Orval Abbey in Belgium.
