Her father Bernabò was a cruel and ruthless despot, and an implacable enemy of the Church. He seized the papal city of Bologna, rejected the Pope and his authority, confiscated ecclesiastical property, and forbade any of his subjects to have any dealings with the Curia. He was excommunicated as a heretic in 1363 by Pope Urban V, who preached crusade against him.[2] When Bernabò was in one of his frequent rages, only Beatrice Regina (her mother) was able to approach him.[3]
Marriage
Antonia was originally betrothed to Frederick III the Simple. This was different from other family marriages because most of Antonia's sisters married members of the House of Wittelsbach. Ten years after the first suggestion of marriage, a marriage contract was drawn up, Antonia's family was to provide a dowry of ten thousand florins plus another twenty thousand in florins jewelry.[4] However, Antonia never married Frederick because he died 27 January 1377 before the marriage could take place. Antonia could have become Queen consort of Sicily if she had married Frederick.
Antonia and Eberhard were married for twenty-five years. On 26 March 1405 Antonia died at Old Castle (Stuttgart), leaving behind her husband and only surviving son. Eberhard remarried after Antonia's death to Elisabeth, daughter of John III, Burgrave of Nuremberg and Margaret of Bohemia. They had a daughter, also called Elisabeth.
