In 1148 Fulk was among those who welcomed Conrad III of Germany when he arrived in Jerusalem on the Second Crusade. He was also sent to meet Louis VII of France, who had stopped in Antioch; Fulk persuaded Louis to continue to Jerusalem rather than remain in Antioch or Tripoli, both of which were ruled by his relatives. In June, Fulk attended the Council of Acre, where the decision was made to attack Damascus, which led to the failure of the Second Crusade.
