Chi ha sposato Ulrich III, Duke of Carinthia?

Ulrich III (c. 1220 – 27 October 1269) was the ruler in the March of Carniola from c. 1249 and Duke of Carinthia from 1256 until his death, the last ruler from the House of Sponheim. His rule had long-lasting consequences. In Carniola, he acquired the former Meranian possessions, thus becoming the first undisputed princeps terrae, provincial lord or landgrave, creating the power and legal basis of the future Duchy of Carniola. The center of his original Carniolan possessions, Ljubljana, became the new administrative center and thus the provincial capital, as well as the center of Ulrich's power. In Carinthia, which he took over after his father's death, his seal became the coat of arms of Carinthia up to today. Despite his attempts to secure the vast Babenberg inheritance through two marriages, first to Agnes of Merania, widow of the last Babenberg duke Frederick II of Austria, and then to Frederick's niece Agnes of Baden, Ulrich remained childless. After a short interregnum by his younger brother Philip of Spanheim, patriarch of Aquileia, the House of Spanheim went extinct, and all of Ulrich's possessions were inherited by his cousin Ottokar II of Bohemia.

Agnes of Merania (c. 1215 – 7 January 1263) was a member of the House of Andechs and an Austrian royal consort. By her two marriages, she was Duchess of Austria from 1230 until 1243 and Duchess of Carinthia from 1256 until her death.

Agnes of Baden (1250 – 2 January 1295), was a German noblewoman by birth member of the House of Baden and by her two marriages Duchess of Carinthia and Countess of Heunburg.

She was the second child of Herman VI, Margrave of Baden and his wife Gertrude, Duchess of Mödling, titular Duchess of Austria and Styria as the last member of the House of Babenberg. For her maternal ancestry, some historians consider Agnes as the last descendant of the Babenbergs.
