Ги де Лузиньян
Bohemond and Raymond III of Tripoli marched to the Kingdom of Jerusalem in early 1180, according to William of Tyre. Baldwin IV of Jerusalem feared that the two princes (who were his father's cousins) had come to dethrone him, the symptoms of his leprosy having become "more and more evident" by that time. Historian Bernard Hamilton, who accepts William of Tyre's narration, says that Bohemond and Raymond came to Jerusalem to choose a husband for Baldwin's sister and heir, Sibylla, wishing to decrease the influence of the king's maternal relatives. However, Baldwin gave her in marriage to Guy of Lusignan, who was supported by their mother, Agnes of Courtenay. Sibylla's marriage contributed to the formation of two parties of noblemen. Bohemond, RaymondIII of Tripoli, and the Ibelin brothers became the leaders of the group that opposed Guy of Lusignan.
