the Historia in French must also be considered suspect, as they were allied to Raymond's supporters in the Ibelin family. The general consensus among recent historians is that although there was a dynastic struggle, "the division was not between native barons and newcomers from the West, but between the king's maternal and paternal kin." Miles of Plancy briefly held the regency for the underaged Baldwin IV. Miles was assassinated in October 1174, and Raymond III was soon appointed to replace him. Raymond named William chancellor of Jerusalem, as well as archdeacon of Nazareth, and on 6 June 1175, William was elected archbishop of Tyre to replace Frederick de la Roche, who had died in October 1174. William's duties as chancellor probably did not take up too much of his time; the scribes and officials in the chancery drafted documents and it may not have even been necessary for him to be present to sign them. Instead he focused on his duties as archbishop.

William was, however, sent by Alexander as an ambassador to Emperor Manuel, and Manuel then sent him on a mission to the Principality of Antioch. William does not mention exactly what happened during these embassies, but he probably discussed the Byzantine alliance with Jerusalem, and Manuel's protectorate over Antioch, where, due to pressure from Rome and Jerusalem, the emperor was forced to give up his attempts to restore a Greek patriarch. William was absent from Jerusalem for two years, returning home in 1180. Patriarchal election of 1180 During William's absence a crisis had developed in Jerusalem. King Baldwin had reached the age of majority in 1176 and Raymond III had been removed from the regency, but as a leper
