In 1177, she married
Raynald of Châtillon, the former
Prince of Antioch, who had recently been released from captivity in
Aleppo. Through Stephanie, Raynald succeeded as lord
jure uxoris of the lordship of Oultrejordain, and used his new position to harass Muslim
caravan and
pilgrimage routes; in 1183 he even threatened to attack
Mecca itself. In 1180,
Baldwin IV of Jerusalem had betrothed his eight-year-old half-sister
Isabella to Stephanie's son Humphrey. The marriage took place in the castle of
Kerak in 1183. The ceremonies were interrupted by the arrival of
Saladin, who
besieged the place in response to Raynald's threats against Mecca. According to the chronicle of
Ernoul, Stephanie sent messengers to Saladin, reminding him of the friendship they shared when he had been a prisoner in Kerak many years before; this is likely a fiction or some mis-remembered event, as Saladin is not otherwise known to have ever been held hostage at Kerak. Saladin did not lift the siege but agreed not to target Humphrey and Isabella's wedding chamber. The siege was soon raised by King Baldwin. The
Old French Continuation of William of Tyre claimed that Stephanie hated Isabella's mother
Maria Comnena, and prevented her having any contact with her daughter. This was probably for political reasons: Baldwin had arranged the marriage to remove the little girl from the influence of her stepfather's family, the
Ibelins. ==Capture of Humphrey==
