Duke Rudolf III. Engraving, 18th century.
Rudolf III, b. presumably 1281, d. Horažd'ovice (Czech Republic), July 4, 1307, Duke of Austria, eldest son of Albrecht I, from 1298 (together with his brothers) Duke of Austria and Styria, 1306 King of Bohemia (and Poland); married the widow of King Wenceslas II, but died young (presumably of dysentery) and was therefore unable to consolidate his position in Bohemia.
