The relationship between Baldwin IV and Guy of Lusignan deteriorated. Baldwin IV removed Guy from the regency and denied his right of succession, making Guy's stepson (Sybilla's son from her first marriage), Baldwin V, his heir and co-ruler on 20 November 1183. A version of Ernoul's chronicle suggests that the child Baldwin V was made heir, because the ailing Baldwin IV wanted to avoid a debate between his sisters' supporters about his succession. Guy's principal supporters, Joscelin of Courtenay and Raynald of Châtillon, were not present at Baldwin V's coronation, because they attended the wedding of Isabella and Humphrey of Toron.
