The moment in context
Edessa fell because it was always the most vulnerable of the four states, lying far inland beyond the reach of the Italian fleets and dependent, like all of Outremer, on its enemies staying divided. Its capture on Christmas Eve 1144 was both a strategic loss and a political opportunity, because it gave the emerging Muslim counter-crusade its first great victory and its first martyr-city. The idea that fighting the Franks was a religious duty rather than a local war did not arise on its own, however, but was deliberately built by poets, jurists and rulers, above all by Nur al-Din. He patronized scholars, preaching and public monuments that tied his own expansion to the defence of Islam and the recovery of Jerusalem, so that religious mobilization served at once to justify war on the Franks and to unite Muslim rivals under his rule.
