 Baldwin IV died in early 1185 . His successor , the child Baldwin V died in late summer 1186 . The High Court of Jerusalem had ruled that neither Baldwin V 's mother , Sybilla ( who was Guy of Lusignan 's wife ) , nor her sister , Isabella ( who was the wife of Raynald 's stepson ) , could be crowned without the decision of the pope , the Holy Roman Emperor , and the kings of France and England about Baldwin V 's lawful successor . However , Sybilla 's uncle , Joscelin III of Courtenay , took control of Jerusalem with the support of Raynald and other influential prelates and royal officials . Raynald urged the townspeople to accept Sybilla as the lawful monarch , according to the Estoire de Eracles . The bailli , Raymond III of Tripoli , and his supporters tried to prevent her coronation and reminded her partisans of the decision of the High Court . Ignoring their protest , Raynald and Gerard of Ridefort , Grand Master of the Knights Templar , accompanied Sybilla to the Holy Sepulchre , where she was crowned . She also arranged the coronation of her husband , although he was unpopular even among her supporters . Her opponents tried to persuade Raynald 's stepson , Humphrey , to claim the crown on his wife 's behalf , but Humphrey deserted them and swore fealty to Sybilla and Guy . Raynald headed the list of secular witnesses in four royal charters issued between 21 October 1186 and 7 March 1187 , showing that he had become a principal figure in the new king 's court .
