Hugh III of Burgundy was expected to come to Jerusalem and marry Sibylla, but Hugh was unable to leave France due to the political unrest there in 1179–1180 following the death of Louis VII. Meanwhile, Baldwin IV's stepmother Maria, mother of Isabella and stepmother of Sibylla, married Balian of Ibelin. At Easter in 1180, Raymond and his cousin Bohemond III of Antioch attempted to force Sibylla to marry Balian's brother Baldwin of Ibelin. Raymond and Bohemond were King Baldwin's nearest male relatives in the paternal line, and could have claimed the throne if the king died without an heir or a suitable replacement. Before Raymond and Bohemond arrived, Agnes and King Baldwin arranged for Sibylla to be married to a Poitevin newcomer, Guy of Lusignan, whose older brother Amalric of Lusignan was already an established figure at court. Internationally, the Lusignans were useful as vassals of Baldwin and Sibylla's cousin Henry II of England. Baldwin betrothed eight-year-old Isabella to Humphrey IV of Toron, stepson of the powerful Raynald of Châtillon, thereby removing her from the influence of the Ibelin family and that of her mother.
