The Second Crusade had been called after the fall of Edessa to Zengi in 1144. In 1147, armies led by Conrad III of Germany and Louis VII of France began their separate journeys to the east; after passing through Constantinople, Conrad suffered a heavy defeat in Anatolia, and retreated to meet Louis at Nicaea. Conrad then spent the winter in Constantinople while Louis continued south to the Mediterranean coast, harassed by the Turks along the way, and finally sailed to Antioch, then ruled by Raymond of Poitiers, uncle of his wife Eleanor of Aquitaine. Conrad arrived at Acre in April, and Louis marched south from Antioch. The nobility of Jerusalem welcomed the arrival of troops from Europe, and it was announced that a council should meet in Acre; as William of Tyre says, "together with the nobles of the realm who possessed an accurate knowledge of affairs and places, they entered into a careful consideration as to what plan was most expedient."
