Outremer
King Baldwin IV
With both Nuradin and Amalric gone, the political situation was thrown well up into the air. While various emirs contested with each other over the regency, Amalric was succeeded by his young son Baldwin IV. But Baldwin's case was tragic. Not only was he only thirteen years old and so a little too young yet to be king in his own right, but signs of leprosy had been recognized in him when he was only nine. Everyone knew that this king would not have a long life.
After a delay of a couple of months, Count Raymond of Tripoli was chosen as regent. There now began to form two factions within the Kingdom that would eventually tear it apart and help lead to its destruction. One faction formed around Raymond of Tripoli. He was supported by many of the local barons, the Order of the Hospital, Reynald of Sidon, the Ibelin family, and the old Constable Humphrey II of Toron.
The other faction consisted of the Templars, the family of the Courtenays, and that of the Lusignans. They found their leader in 1175 when Reynald of Châtillon and Joscelin of Courtenay were both released from captivity by the atabeg of Aleppo. The young king tried to steer a course between them, but it was exceedingly difficult. Given the ferocity of the rivalry and the King's illness, it's amazing that he held out so well.
