Second Crusade (1147 – 1149)
The conquest of County of Edessa by the Seljuk Zengi, governor of Mosul in 1144 did not particularly upset other Crusader States in the Holy Land but when the news of the fall of Edessa reached Europe the interest for the Crusades was renewed, especially among clergy. Pope Eugene III commissioned St. Bernard of Clairvaux to preach the Second Crusade which initially was not so well responded as the First Crusade. However, St. Bernard’s powerful eloquence and his allegedly miraculous cures greatly raised the interest for the Second Crusade and Louis VII of France and Conrad III of Germany decided to lead the Crusade.
The Second Crusade was launched in 1147. Conrad III of Germany left first, while Louis VII of France departed in 1148. Conrad’s forces in Asia Minor were decimated before they merged with the French in 1148, while joined Siege of Damascus failed probably because of the treachery of their allies. In 1148, Conrad III of Germany returned to Europe and Philip VII of France followed him one year later. Thus the Second Crusade ended as failure in 1149.
