Amalric was 27, and therefore unlike Baldwin needed no regent (besides, his mother Queen Melisende had died on 11 September 1161) and was ready to rule. Unfortunately, the High Court refused to recognize him as king until he got rid of his wife, Agnes of Courtenay, for reasons on which historians cannot agree.
Amalric and Agnes already had children, and the need for an heir was a concern. Amalric gained papal agreement from Pope Alexander III that his children would be seen as legitimate even if his marriage was annulled. The marriage was annulled on the grounds of consanguinity.
Eight days after Baldwin's death, he was interred in the Church of the Holy Sepulchre. On the same day in the same place, Amalric was crowned (see illustration) by the patriarch, Amalric of Nesle, the chief spokesman who told him he had to give up Agnes. (Although king and patriarch often worked together, this king excluded this patriarch from his councils, possibly because of the Agnes decision.)
One of Amalric's first pieces of legislation was the Assise sur la ligece ("Assize on liege-homage"). This dec laced all lords to be vassals of the king. This change allowed the vassals of Amalric's vassals to appeal directly to the king if they felt their overlords were not being fair or trustworthy. It disallowed the seizing of fiefs by lords, but allowed the king to confiscate fiefs from anyone.
Amalric's chief military goal during his reign was to conquer Egypt. This was not just a "land grab." The Crusaders were constantly threatened by Muslim neighbors, chief of whom was Nur ad-Din, Emir of Aleppo since 1146. Nur ad-Din also saw the strategic importance of Egypt: if he could control it, he was have the Crusader states surrounded.
The next decade saw these two men working against each other over Egypt. So let's learn more about Nur ad-Din next time.
