Balian of Ibelin
After Queen Sybilla's death in the autumn of 1190, most barons of the realm (including Isabella's stepfather, Balian of Ibelin) wanted to give Isabella in marriage to Conrad of Montferrat, a successful military leader. The marriage of Humphrey and Isabella was annulled, although they protested the decision. Humphrey joined the retinue of King Richard I of England during his crusade in 1191–1192. Since Humphrey was fluent in Arabic, he conducted negotiations with Saladin's brother, Al-Adil, on Richard's behalf.
