Ulrich III, d. Cividale (Italy), Oct. 27, 1269, Master of Carniola and last Duke of Carinthia (1256-1269) of the Sponheimer dynasty; son and descendant of Bernhard von Sponheim. Came to an agreement with his brother Philipp von Sponheim, the Archbishop of Salzburg, that the latter should become Duke in the event of his death. One of Ulrich's sons from his first marriage died at a young age, his second marriage to Agnes von Baden, daughter of Gertrud (of the Babenberg dynasty), remained childless. After his death Carinthia came into the hands of Přemysl Ottokar II of Bohemia, whom Ulrich had made heir instead of his brother Philipp in the "Podiebrad Testament" of Dec. 4, 1268.
