The idea
This topic traces how Muslim power grew between 1144 and 1169. In 1144 Zingi, ruler of Mosul and Aleppo, captured the city of Edessa; this shocked Latin Christendom and prompted the Second Crusade. After Zingi’s death in 1146, his son Nur ad-Din consolidated power in Syria by 1154, taking Damascus and uniting Muslim Syria against the Franks. Nur ad-Din’s growing rift with Saladin developed after Saladin’s rise in Egypt: although Saladin nominally served Nur ad-Din, he acted independently, refused to attend Nur ad-Din’s court, and sought his own authority. The rift reflected competition for leadership of the Muslim counter-crusade and shaped later conflict.
What earns the marks
- Explains Zingi’s capture of Edessa in 1144 as a turning point that severely weakened the crusader state and triggered the Second Crusade.
- Analyses how Nur ad-Din consolidated power in Syria between 1146 and 1154, including the acquisition of Damascus and the elimination of rival Muslim rulers.
- Explains the significance of Nur ad-Din’s consolidation for the Muslim response to the crusades, such as greater unity and pressure on the Latin states.
- Analyses the growing rift between Nur ad-Din and Saladin, including Saladin’s independent actions in Egypt and Nur ad-Din’s suspicion or demands for obedience.
- Evaluates the extent to which Muslim power had grown by 1169, considering both Zingi’s and Nur ad-Din’s achievements and the limits of unity.
Common mistakes and how to put them right
Confusing Zingi with Nur ad-Din.
Put it right: Keep their roles and dates distinct.
Treating the rift with Saladin as a sudden event rather than a gradual development rooted in Saladin’s independent rule in Egypt.
Put it right: Explain the sequence and causes of the growing tension.
Assuming Edessa’s fall immediately destroyed the entire county of Edessa.
Put it right: The county survived in reduced form until 1150, when the remnant was sold to Byzantium following Joscelin II's capture.
Exam tips
- Use precise dates and place names to anchor your argument, for example 1144, 1146–54, Damascus, Edessa.
- When discussing the rift, explain both Nur ad-Din’s perspective and Saladin’s actions to show causation.
