The preaching of the Second Crusade; its course and outcome

The idea

Triggered by the fall of Edessa in 1144, the Second Crusade was formally launched by Pope Eugenius III's bull Quantum praedecessores. Bernard of Clairvaux’s charismatic preaching galvanised mass participation, recruiting King Louis VII at Vézelay in 1146 and King Conrad III later at Speyer. The crusade's course was disastrous; both armies suffered heavy losses traversing Anatolia due to Seljuk attacks and logistical failures. Reaching the Levant, the leaders held the Council of Acre in 1148 and disastrously decided to attack Damascus, a former ally. The siege failed within days due to poor positioning and lack of water. The outcome was a humiliating retreat, damaging the prestige of the crusading movement and leaving Outremer highly vulnerable.

What earns the marks

• Assess the role of Bernard of Clairvaux and the papal bull Quantum praedecessores in mobilising European monarchs and popular support.
• Evaluate the logistical and military failures of the French and German armies during their march across Asia Minor.
• Analyse the strategic decision-making at the Council of Acre and the subsequent failed siege of Damascus in 1148.
• Explain the immediate outcomes of the crusade, including the collapse of the expedition and the return of the monarchs in disgrace.

Common mistakes and how to put them right

• Claiming the crusade was launched to recapture Jerusalem.

  Put it right: It was actually triggered by Zengi's capture of Edessa in 1144.

• Confusing the routes of the French and German armies.

  Put it right: Conrad III marched ahead and was defeated at Dorylaeum before Louis VII arrived.

• Stating that Damascus was a hostile Muslim stronghold prior to the crusade.

  Put it right: It was actually allied with Jerusalem against Nur ad-Din before the crusaders attacked it.

• Assuming Bernard of Clairvaux recruited both kings at Vézelay.

  Put it right: Conrad III actually took the cross later at Speyer.

Exam tips

• Link the failure of the crusade directly to the divided leadership and poor strategic choices, such as the attack on Damascus.
• Use Bernard of Clairvaux as a primary example of how crusading ideology was communicated and popularised in the Latin West.
• Contrast the high expectations set by the involvement of European monarchs with the reality of their military defeats in Anatolia.
