Zengid dynasty
Whatever the reasons for the Siege of Damascus were, the results were disastrous for the crusaders. The combined forces besieged the city in July, but the campaign was a terrible blunder and failed after only four days. The crusaders blamed each other and there were rumours of bribery. Conrad and Louis lingered in Jerusalem for some time, accomplishing nothing, before returning to Europe. Just as had been feared, Nur ad-Din used the opportunity to impose his power over Damascus, and was in personal control of the city by 1154. The general historical debate now appears to view the decision to attack Damascus as somewhat inevitable. The campaign is viewed by historians, such as Martin Hoch, that the decision was the logical conclusion of Damascene foreign policy shifting into alignment with the Zengid dynasty. King Baldwin III had previously launched a campaign with the sole objective of capturing the city. This aided in shifting the Burid dynasty's relations with the Kingdom of Jerusalem.
