In 1137 and 1142, Byzantine emperor John II Comnenus arrived in Syria attempting to impose Byzantine control over the crusader states. John's intention of making a pilgrimage, accompanied by his impressive army, to Jerusalem alarmed Fulk, who wrote to John pointing out that his kingdom was poor and could not support the passage of a large army. This lukewarm response dissuaded John from carrying through his intention, and he postponed his pilgrimage. John died before he could make good his proposed journey to Jerusalem.
