Elizabeth's family, the House of Gorizia, had been staunch supporters of the Emperor in the struggle against the papacy. In the 13th century, they had been loyal allies of the Hohenstaufens against the Spanheim dukes of Carinthia who had sided with the papacy. Elizabeth's father and uncle were half-brothers of Conradin, the last Hohenstaufen scion. The connection with the Aragonese rulers in Sicily was thus natural, even though they were too far apart to have a tangible common interest at the time of Elizabeth's betrothal. Perhaps, the marriage was aimed to check the rising Angevin influence in Central Europe after Charles I's ascension to the Hungarian throne, especially since the Anjou allies in Croatia were in conflict with the Carinthian dukes.
