Rudolf I of Bohemia
Rudolf I of Habsburg (c. 1281–1307), called the Good, was the eldest son of King Albert I of Germany and Elizabeth of Gorizia-Tyrol. From 1298 he ruled the Austrian and Styrian duchies as his father's co-ruler and acted as regent for his younger brothers.
His first wife Blanche of France died in 1305, after their two children had died young. After King Wenceslaus III of Bohemia was murdered in August 1306, Albert seized Bohemia and had Rudolf crowned king, marrying him to Elizabeth Richeza, widow of Wenceslaus II.
Many Bohemian nobles rejected him and rose in favour of Henry of Carinthia. While besieging the rebel castle of Horažďovice, Rudolf died of dysentery in July 1307, leaving no heir.
