Your route through the period
This course follows three major crusading expeditions and the Latin-ruled states established after the conquest of Jerusalem. It begins with the worlds of Latin Christendom, Byzantium and the Islamic Near East in 1095. It then asks why the First Crusade succeeded, how Outremer survived, why the Second Crusade failed and what the Third Crusade achieved after Saladin captured Jerusalem.
Use four connected sections:
- The First Crusade, 1095-1099
- The Crusader States in the twelfth century
- The Second Crusade, 1144-1149
- Saladin and the Third Crusade, 1187-1192
Avoid a simple “Christian West versus Muslim East” story. Latin Christians, Byzantines, eastern Christians, Jewish communities and several Muslim powers had different interests. Alliances crossed religious boundaries, while conquest, legal inequality and severe violence remained central.
Starting world: three connected regions
Western Europe contained competing rulers, reforming churchmen, monasteries, towns and warrior elites. Pilgrimage to Jerusalem already mattered. Church leaders increasingly tried to direct aristocratic violence toward causes they judged legitimate.
The Byzantine Empire was a Christian state centred on Constantinople. Emperor Alexios I Komnenos needed military help after Turkish advances in Anatolia, but he wanted disciplined forces serving Byzantine strategy, not an independent mass movement.
The Islamic Near East was not one state. Seljuk rulers, local Turkish commanders, Arab dynasties and the Fatimid caliphate in Egypt competed. Sunni and Shia political-religious divisions mattered, but so did dynastic rivalry and local survival.
Vocabulary bridge
- Crusade: a papally authorised expedition understood by participants as penitential warfare and pilgrimage.
- Crusader vow: a religious commitment marked by taking the cross.
- Indulgence: remission of temporal punishment for confessed sin under the Church’s stated conditions.
- Outremer: “the land beyond the sea,” used for the Latin-ruled states in the eastern Mediterranean.
- Franks: a broad contemporary label often used for western Latin Christians in the region.
- Jihad: striving in God’s cause; in this course, especially the changing use of armed jihad in Muslim political and religious mobilisation.
- Military order: a religious institution combining communal vows with armed defence, notably the Templars and Hospitallers.
1. The First Crusade, 1095-1099
Why was it called?
Alexios appealed westward for assistance. Pope Urban II used the opportunity to advance papal leadership, aid eastern Christians and direct an armed expedition toward Jerusalem. At Clermont in November 1095, he promised spiritual benefit to participants.
No exact transcript of Urban’s speech survives. Later accounts agree on aid, pilgrimage, liberation and spiritual reward, but historians must not combine every reported phrase into one verbatim speech.
Preachers spread the call. Participants acted through interacting motives:
- penitential devotion and hope of salvation;
- attachment to Jerusalem and pilgrimage;
- loyalty to kin, lords and companions;
- honour and reputation;
- concern for fellow Christians;
- adventure or material opportunity.
Crusading was costly. Many participants sold, mortgaged or arranged property to go, so greed alone is not a convincing general explanation.
The People’s Crusade and anti-Jewish violence
Popular groups left before the main princely armies. Some attacked Jewish communities in Rhineland towns in 1096. These massacres were not a necessary response to Alexios’s appeal; they show how crusading enthusiasm, prejudice, coercion and opportunism could combine.
The People’s Crusade was largely destroyed after crossing into Anatolia. Its fate should not be confused with the later campaign of the princes.
How did the main campaign survive?
The princely armies included contingents associated with Bohemond of Taranto, Raymond of Toulouse, Godfrey of Bouillon and others. They had no single commander. Alexios transported them across the Bosporus and sought oaths concerning former Byzantine territory.
The journey demanded food, animals, siege equipment, intelligence and negotiation. Crusaders won at Dorylaeum in 1097 but suffered from heat, thirst and losses across Anatolia. Baldwin established control at Edessa in 1098. Antioch was captured after a long siege, then the victors themselves faced siege.
Success came from several connected factors:
- endurance and religious cohesion during crisis;
- experienced mounted and infantry forces;
- adaptation in battle and siege;
- Byzantine transport, supplies and early assistance;
- cooperation despite divided leadership;
- political rivalry among opponents;
- the inability of regional Muslim rulers to coordinate in time.
Jerusalem
The crusaders reached Jerusalem in June 1099 and captured it on 15 July. Muslim and Jewish inhabitants were killed in large numbers. The conquest established Latin rule but did not end conflict or secure every route and settlement.
Knowledge check
- How did Alexios’s aims differ from Urban II’s?
- Why is a single-motive explanation of participation weak?
- How did Byzantine aid contribute to success?
- How did political division among opponents matter?
- Why was success contingent rather than inevitable?
Teaching feedback: A strong explanation connects motives, leadership, logistics, adaptation and opponents. It neither sanitises religious violence nor treats medieval belief as a disguise for greed.
2. The Crusader States in the twelfth century
Four distinct polities
The crusaders created the County of Edessa, Principality of Antioch, County of Tripoli and Kingdom of Jerusalem. They were connected but not identical. Edessa was inland and exposed; Antioch faced Byzantine as well as Muslim pressure; Jerusalem developed the strongest monarchy and access to important ports.
Latin elites ruled diverse populations including eastern Christians, Muslims and Jews. Government used western practices alongside existing local systems. Society involved conquest and legal hierarchy, but also taxation, trade, diplomacy, translation and daily contact. “Perfect coexistence” and “constant religious war” are both misleading.
Rulers and succession
Baldwin I expanded Jerusalem and secured ports. Baldwin II managed northern crises and succession. After his death, his daughter Melisende ruled with Fulk and later exercised power during her son Baldwin III’s minority. Conflict between mother and son ended with Baldwin III taking full control in 1152.
Women were not outside politics: inheritance, marriage, regency and household networks shaped government. Later, Baldwin IV’s leprosy and the question of succession encouraged faction. By 1186, Guy of Lusignan and Queen Sibylla held the crown amid deep rivalry.
Why did the states survive?
Several factors interacted:
- Muslim political division: rival rulers sometimes fought one another or allied with Latin powers.
- Kingship and diplomacy: capable rulers negotiated truces, marriages and alliances.
- Ports and maritime connections: Italian cities, pilgrims and shipping brought money, people and supplies.
- Finance: taxation, agriculture, customs and commerce supported rule.
- Fortifications: castles protected routes, lordship and vulnerable frontiers.
- Military orders: the Templars and Hospitallers supplied professional fighters, garrisons and international resources.
- Western aid: expeditions and individuals helped, but support was irregular.
- Pragmatism: limited manpower encouraged truces and avoidance of unnecessary battle.
No factor worked alone. Castles required troops and money. Western aid depended on ports. Muslim disunity helped only if Latin rulers used the opportunity effectively.
Knowledge check
- Why should Outremer not be treated as one uniform state?
- How did ports support survival?
- Why were castles important but insufficient?
- What does Melisende’s career reveal about rulership?
- How did manpower shortage affect strategy?
Teaching feedback: Compare factors using duration, reach and dependence. Ask what changed when Muslim rulers became more coordinated.
3. The Second Crusade, 1144-1149
The fall of Edessa and the call
Zengi, ruler of Mosul and Aleppo, captured Edessa in December 1144. The loss exposed the northern frontier. Pope Eugenius III authorised a new crusade. Bernard of Clairvaux preached it powerfully, while King Louis VII of France and King Conrad III of Germany took the cross.
Separate the trigger from wider mobilisation. Edessa created urgency; papal authority, Bernard’s preaching, royal politics, reputation and penitential devotion shaped the response.
Losses in Anatolia
The German and French forces travelled separately and suffered heavily in Anatolia. Supply, terrain, command, Turkish tactics and poor coordination weakened them. Relations with Byzantium were distrustful, but blaming the emperor for “betrayal” repeats partisan explanations and hides western mistakes.
At Antioch, Raymond of Poitiers urged Louis to campaign in the north. Louis instead continued towards Jerusalem. Leaders assembled at Acre in 1148 and chose Damascus as their target.
Why did Damascus fail?
Damascus had sometimes cooperated with Jerusalem against common enemies. Attacking it was not wholly irrational: leaders could imagine controlling a wealthy strategic city. Yet the siege collapsed after only a few days.
Reasons included:
- disagreement over aims and future control;
- weak coordination among royal and local leaders;
- difficult supply and movement around the city;
- strong resistance;
- fear that relief forces were approaching;
- mistrust after the army changed its position.
The failure damaged western prestige and relationships with Outremer. It also made cooperation between Damascus and Nur al-Din more likely. Muslim political and religious mobilisation strengthened gradually; it was not an instant united response.
Knowledge check
- What was the difference between the fall of Edessa and Bernard’s role?
- Why were the Anatolian losses important?
- Why is Byzantine betrayal an inadequate explanation?
- Why did leaders choose Damascus?
- How did failure change the political balance?
Teaching feedback: Build a causal chain from Edessa to mobilisation, weakening in Anatolia, disagreement in Outremer, failure at Damascus and longer-term consequences.
4. Saladin and the Third Crusade, 1187-1192
From Zengi to Saladin
Zengi used jihad language but also pursued dynastic power. His son Nur al-Din expanded authority in Syria and promoted religious legitimacy. Saladin first rose through service in Egypt, ended the Fatimid caliphate there and gradually brought Egypt and much of Syria under his rule.
There was no single master plan passing unchanged between three leaders. Each faced Muslim rivals as well as Latin opponents. Yet political consolidation and jihad mobilisation increasingly changed the balance around Outremer.
Hattin and Jerusalem, 1187
Jerusalem’s succession crisis, faction and Reynald of Chatillon’s attacks increased tension. When Saladin invaded, Guy of Lusignan led the main Latin army away from water toward Tiberias. At Hattin on 4 July, heat, thirst, terrain, pressure and Saladin’s larger coordinated force destroyed it.
Hattin removed much of Jerusalem’s field army. Many settlements then fell. Jerusalem surrendered in October. There was ransom, enslavement and coercion, although not a repetition of the general massacre of 1099.
Avoid a hero-and-villain account. Guy’s decisions mattered, but so did structural manpower weakness and Saladin’s resources. Saladin was neither merely tolerant nor uniquely cruel; Richard was neither a perfect knight nor only a brutal invader.
The Third Crusade
Frederick Barbarossa led a major German force overland but drowned in 1190, and much of his expedition dispersed. Philip II of France and Richard I of England arrived by sea. Acre surrendered in 1191 after a long siege. Leadership rivalry continued, and Philip returned home.
Richard defeated Saladin’s forces at Arsuf and restored coastal positions. He approached Jerusalem but did not attack. Capturing the city was not the same as holding it: water, supply, weather, Saladin’s remaining army and the risk to the coast all mattered.
Richard defended Jaffa in 1192 and negotiated a settlement. Jerusalem remained under Saladin, but the Latin states retained a coastal strip and Christian pilgrims gained access to holy places.
How successful was it?
Use several criteria:
- Sacred objective: Jerusalem was not recovered.
- Territory: Acre and a viable coastal state were secured.
- Survival: Outremer continued.
- Leadership: victories did not remove rivalry or limited resources.
- Diplomacy: negotiation gained access and a truce.
- Long-term outcome: neither side achieved a final settlement.
The crusade therefore failed at its most visible objective but reversed much of the immediate collapse of 1187.
Knowledge check
- How did jihad and dynastic ambition interact?
- Why was Hattin a political and military turning point?
- Why did Frederick’s death matter?
- Why did Richard decide against attacking Jerusalem?
- Which criteria produce different judgements of success?
Teaching feedback: A high-level judgement weighs Jerusalem against territorial recovery, survival and diplomacy. It does not become a personality contest between Richard and Saladin.

How to answer the 10-mark comparison
Explain both named factors through the same outcome and criteria.
A reliable structure:
- Define the outcome.
- Explain factor (i) with precise evidence.
- Explain factor (ii) with precise evidence.
- Compare reach, timing and dependence.
- Reach a supported judgement.
Practice comparison
Which was more important to the survival of the Crusader States?
(i) aid from the West
(ii) Muslim political disunity
A strong answer tests how consistently each factor operated and whether Latin rulers could survive when Muslim coordination increased.
How to answer the 20-mark judgement
Build a sustained argument across factors or phases. Use precise evidence and test the wording throughout.
Practice judgement
“Muslim disunity was the most important reason for the success of the First Crusade.” How far do you agree?
Compare divisions among opponents with leadership, endurance, military adaptation, Byzantine help and religious cohesion. Show how factors depended on one another.
Final retrieval check
Without looking back, explain:
- Why Urban II’s crusade differed from Alexios’s request.
- Why participants’ motives cannot be reduced to greed.
- Why the First Crusade succeeded despite divided leadership.
- How Outremer’s ports, finance and diplomacy supported survival.
- Why Melisende matters.
- Why the Second Crusade was called.
- Why it failed at Damascus.
- How Nur al-Din and Saladin changed the regional balance.
