to return to Hungary. Shortly thereafter, the marriage was formally dissolved. Eventually, in 1254, Gertrude received a portion of Styria, 400 silver marks annually, and the towns of Voitsberg and Judenburg as her residences. In 1267, as neither Gertrude nor her son Frederick forswore their claim to the duchies of Styria and Austria, King Ottokar II dispossessed them of their lands. Ottokar was largely motivated since he sought to remarry into the Hungarian royal house; he could not expect an heir with the significantly older and barren Margaret. That same year, the death of Margaret made Gertrude the only legitimate heir to the Babenberg dynasty. Decline On 8 September 1268, Gertrude's son Frederick, who had accompanied Conradin on his Italian expedition, was captured in Astura to the south of Anzio. Handed over to Charles of Anjou, he remained in degrading imprisonment in the Castel dell'Ovo in Naples until his public beheading in the Piazza del Mercato in Naples on 29 October. The following year, Gertrude was exiled and lost her claim to Windisch-Feistritz. Again, she found refuge with her family in Meissen. Gertrude's other claims were ultimately lost when Rudolf I of Germany granted her duchies to his own sons in 1282. Six years later, on 24 April 1288, Gertrude died in the Poor Clare convent of Saint Afra near Seusslitz in Meissen. She was buried in this monastery. Her daughter Agnes of Baden became mother and brother's heir, but in 1279, renounced her rights to Baden and the Duchies of Austria and Styria. From her second marriage with Count Ulrich III of Heunburg, Agnes had five children, two sons (Frederick and Herman) and three daughters (Margaret, Elisabeth and Katharina). The sons died without heirs. The eldest daughter, Katharina, married the Styrian nobleman Ulrich of Sanneck, and their son Frederick I of Cilli eventually inherited his grandfather's estates. He founded the House of Cilli, which included Holy Roman Empress Barbara of Cilli whose daughter, Elizabeth of Luxembourg, married into the House of Habsburg. Gertrude's youngest daughter, Maria Romanovna of Halicz, born from her third marriage, married in the second half of the 1260s with Joachim Gutkeled, Ban of Slavonia between 1270 and 1272 (with short interruption) and from 1276 to 1277, and three times Master of the treasury between 1272 and 1275. He was also ispán, or head, of many counties, including Baranya and Pozsony. The couple produced only an
