1A The Age of the Crusades, c1071–1204 – The Third and Fourth Crusades, 1187–1204 (A-level only) explained
The 1187 fall of Jerusalem prompted Pope Gregory VIII to issue Audita tremendi, preaching the Third Crusade by framing the loss as divine punishment.
Read the full explanation
Preparation involved unprecedented financial levies, notably the Saladin Tithe. Motives varied among the monarchs. Henry II of England and Philip II of France were initially reluctant, driven more by their Angevin-Capetian territorial rivalry than piety, taking the cross to avoid losing face. Following Henry's death, Richard I's motives combined genuine religious zeal with a desire for chivalric glory. Holy Roman Emperor Frederick Barbarossa, a veteran of the Second Crusade, sought to assert his imperial authority and demonstrate his role as the secular leader of Christendom by raising a massive German army.
The course of the Third Crusade: leadership and internal rivalries of the Crusaders; the reasons for the military outcome
The Third Crusade's course was heavily dictated by the fractured leadership and intense internal rivalries among the crusaders. Following Frederick Barbarossa's accidental drowning in 1190, the German contingent largely disintegrated, shifting the leadership burden to Richard I and Philip II. Their relationship rapidly deteriorated during the siege of Acre over disputes regarding the division of spoils and the claimant to the throne of Jerusalem (Guy of Lusignan versus Conrad of Montferrat). Philip's early departure in 1191 left Richard in command. Despite Richard's tactical brilliance at Arsuf and Jaffa, the military outcome—a negotiated truce rather than the recapture of Jerusalem—was caused by his depleted forces, the constant threat to his supply lines, and Saladin's resilient defensive strategy.
The impact of the Third Crusade; Saladin’s power and prestige in the Muslim Near East
The Third Crusade (1189–1192) significantly impacted the Crusader States by securing their survival for another century, despite failing to recapture Jerusalem. The Treaty of Jaffa (1192) consolidated Christian control of the Levantine coast from Jaffa to Tyre, ensuring vital maritime supply lines. For Saladin, the crusade had a complex effect on his power and prestige in the Muslim Near East. While he successfully defended Jerusalem, enhancing his reputation as the champion of jihad, his failure to expel the Franks entirely and the loss of Acre damaged his military aura. Furthermore, the prolonged conflict exhausted his treasury and strained his fragile coalition of emirs, leading to immediate fragmentation of his Ayyubid empire upon his death in 1193.
The origins of the Fourth Crusade; the papacy of Innocent III; the weakness of the Byzantine Empire; the role of Venice
The Fourth Crusade (1202–1204) originated from Pope Innocent III’s 1198 encyclical Post miserabile, which sought to recapture Jerusalem. The strategy to attack the Ayyubid power base in Egypt emerged later during crusade councils. The crusade was derailed by logistical failures and geopolitical opportunism. The role of Venice was pivotal; Doge Enrico Dandolo provided the fleet but, when the crusaders could not pay the 85,000 silver marks owed, diverted the army to attack Zara. Concurrently, the weakness of the Byzantine Empire, plagued by dynastic instability following the deposition of Isaac II, created a fatal vulnerability. Prince Alexios's promises of financial aid ultimately led to the catastrophic sack of Constantinople in 1204.
The course of the Fourth Crusade: military preparations; the diversion to Zara; the failure to make any impact on Muslim power
The Fourth Crusade's military preparations were fatally flawed by the Treaty of Venice (1201). Envoys contracted a fleet for 33,500 men, but only around 12,000 arrived, leaving the crusaders unable to pay the 85,000 silver marks owed to the Venetians. To settle this debt, Doge Enrico Dandolo proposed a diversion to Zara, a Christian city in Dalmatia, which the crusaders besieged in 1202 despite papal prohibition. This diversion set a precedent for prioritising political and financial needs over religious goals. Consequently, the crusade failed to make any impact on Muslim power; the army never reached its intended target of Egypt or the Holy Land, instead diverting again to sack Constantinople in 1204, entirely abandoning the fight against Islam.
The legacy of the Crusades by 1204: the Muslim Near East, the Byzantine Empire and the Latin West
By 1204, the crusades had left a profound legacy across three distinct spheres. In the Muslim Near East, the crusader threat had catalysed Islamic unification under the Ayyubid dynasty, cementing the ideology of jihad and leaving Muslim powers largely dominant despite the survival of a reduced Outremer. For the Byzantine Empire, the legacy was catastrophic; the 1204 sack of Constantinople shattered the empire, replacing it with a fragile Latin Empire and deeply fracturing Orthodox-Catholic relations. In the Latin West, crusading had evolved into a formalised institution that expanded papal authority, stimulated the growth of Italian maritime republics through lucrative Mediterranean trade networks, and introduced new systems of taxation to fund future military campaigns.

Common Mistakes
- Claiming Henry II led the English contingent on the crusade. Correction: Henry II took the cross but died in 1189 before departing; his son Richard I actually led the English forces.
- Assuming Philip II and Richard I shared identical, purely religious motives. Correction: Philip was highly pragmatic and focused on French territorial gains, whereas Richard was heavily motivated by chivalric glory and genuine piety.
- Stating that preaching the crusade was universally successful without resistance. Correction: Acknowledge that the heavy taxation of the Saladin Tithe caused significant resentment and resistance among the laity and clergy.
- Stating that the Third Crusade was a complete failure because Jerusalem was not captured. Correction: Recognise that the crusade was a partial success, as it secured the coastal cities, captured Cyprus, and guaranteed unarmed Christian access to Jerusalem.
- Attributing the failure to take Jerusalem solely to Richard I's lack of commitment. Correction: Explain that Richard's decision to turn back was based on sound military logistics, as he lacked the manpower to hold the city even if he captured it.
- Ignoring the role of Saladin's tactics in the military outcome. Correction: Include Saladin's scorched-earth policy, poisoning of wells, and preservation of his army as key factors in preventing a crusader victory.
- Claiming the Third Crusade was a complete failure; correction: acknowledge that while Jerusalem was not taken, the crusade successfully secured the coastal cities and ensured the survival of the Crusader States.
- Assuming Saladin emerged from the crusade with absolute, unchallenged power; correction: recognise that the prolonged war drained his resources and strained his alliances, leaving his empire vulnerable to fragmentation.
- Stating that Saladin lost Jerusalem during the Third Crusade; correction: Saladin successfully defended Jerusalem, which remained in Muslim hands, though he conceded coastal territories like Acre.
- Stating that Innocent III planned the attack on Constantinople from the beginning; correction: Innocent III explicitly forbade attacks on fellow Christians, though he lost control of the expedition.
- Blaming the diversion solely on Venetian greed; correction: acknowledge the complex interplay of the crusaders' financial shortfall, the Treaty of Venice, and the opportunistic promises of Prince Alexios.
- Assuming the Byzantine Empire was militarily strong but surprised; correction: highlight the chronic internal weaknesses, factionalism, and depleted treasury that left Constantinople vulnerable.
- Claiming that Post miserabile explicitly targeted Egypt; correction: the encyclical called for the recapture of Jerusalem, while the Egyptian strategy was formulated later by crusade leaders.
- Error: Claiming the original target of the Fourth Crusade was Constantinople. Correction: The original secret target was Egypt, to attack the Ayyubid power base before moving to Jerusalem.
- Error: Stating the Pope supported the attack on Zara. Correction: Pope Innocent III explicitly forbade the attack on the Christian city of Zara and excommunicated the crusaders when they proceeded.
- Error: Assuming the crusaders fought Muslim armies during this campaign. Correction: The Fourth Crusade never engaged Muslim forces, fighting only fellow Christians at Zara and Constantinople.
- Error: Arguing that the Byzantine Empire was completely destroyed in 1204. Correction: While severely fractured and replaced centrally by the Latin Empire, Byzantine successor states like Nicaea and Trebizond survived.
- Error: Claiming the Muslim Near East was weakened by the crusades by 1204. Correction: The Muslim Near East was actually more unified and militarily formidable under Ayyubid control than it had been in 1095.
- Error: Viewing the legacy in the Latin West solely in religious terms. Correction: The legacy in the West was heavily economic and political, including the rise of Italian city-states and new taxation systems.
