When did Muslims capture Edessa and defeat crusaders at Damascus?

Muslims captured Edessa in 1144, which was a significant event leading to the Second Crusade. The defeat of the Crusaders at Damascus occurred in July 1148 during this same crusade, when the Muslim forces, led by Nur ad-Din, successfully repelled the siege by the Crusader army. These events marked crucial turning points in the struggle between Crusaders and Muslim forces in the region.
