With a woman and a child ruling Jerusalem, the political situation was somewhat tense; the northern crusader states of Tripoli, Antioch, and Edessa increasingly asserted their independence, and there was no king to impose the suzerainty of Jerusalem as Baldwin II or Fulk had done.

In 1144, Zengi captured Edessa, which shocked the Western world and led to the Second Crusade.
