282 A BRIEF SURVEY OF HUMAN HISTORY dom of Jerusalem with Godfrey of Bouillon as its king. This king died in 1101 and the kingdom relapsed into feu- dal anarchy. The Holy Places had to be consequently de- fended by bodies of volunteers such as the Orders of the Templars, the Hospitalers, and the Teutonic Knights. The Second Crusade was provoked by the massacre of 30,000 Christians at Edessa by the Turks in 1147. It was led by Conrad III of Germany and Louis VII of France, and yet it ended in a fiasco.

Instead of directly concentrat- ing on their main objective the misguided Crusaders attack- ed Christian places like Zara and Constantinople on their way. For the time being the so-called Latin Empire was established in the East. But Constantinople was again cap- tured by the Greeks with the assistance of the Genoese, about sixty years later.

The fail- ure of many a Crusade was attributed to the sinfulness of the Crusaders. So it was believed that an army of inno^ cents would be certainly invincible : "Out of the mouths, of babes and sucklings hast thou ordained strength." No less
