Her marriage to King Ladislaus, took place celebrated in Gaeta in 1389 when she was 12, was calculated to bring her family's financial and military support, and not adversity, to his rule.The fortunes of the Chiaramonte family changed after her father died in 1391, and her brother was caught and executed by the forces of King Martin of Aragon, who had declared himself king of Sicily. With this turn of fortunes, Ladislaus obtained an annulment by decree of the pope Boniface IX. In July 1392, the bishop of Gaeta and Cardinal Acciaioli announced the dissolution of the marriage in church. The supposed reason for the annulment was either the age of the couple or the accusation that Costanza's mother was living dissolutely in concubinage.
