Conquest of Syria (1260)

In 1260 Mongol forces combined with those of their Christian vassals in the region, including the army of the Armenian Kingdom of Cilicia under Hethum I, King of Armenia and the Franks of Bohemond VI of Antioch. This force conquered Muslim Syria, a domain of the Ayyubid dynasty. They captured Aleppo by siege and, under the Christian general Kitbuqa, seized Damascus on 1 March 1260. A Christian Mass was celebrated in the Umayyad Mosque and numerous mosques were profaned. Many historical accounts describe the three Christian rulers Hethum, Bohemond, and Kitbuqa entering the city of Damascus together in triumph, though some modern historians such as David Morgan have questioned this story as apocryphal.

The invasion effectively destroyed the Ayyubids, which was until then a powerful dynasty that had ruled large parts of the Levant, Egypt, and the Arabian Peninsula. The last Ayyubid king, An-Nasir Yusuf, had been killed by Hulegu this same year. With Baghdad ravaged and Damascus weakened, the center of Islamic power shifted to the Mamluk sultan's capital of Cairo.

Hulegu intended to send forces southward through Palestine toward Cairo. So he had a threatening letter delivered by an envoy to the Mamluk Sultan Qutuz in Cairo demanding that Qutuz open his city or it would be destroyed like Baghdad. Then, because food and fodder in Syria had become insufficient to supply his full force, and because it was a regular Mongol practice to move troops to the cooler highlands for the summer, Hulegu withdrew his main force to Iran near Azerbaijan, leaving behind one tumen (10,000 men or less) under Kitbuqa, accompanied by Armenian, Georgian, and Frankish volunteers, which Hulegu considered sufficient. Hulegu then personally departed for Mongolia to play his role in the imperial succession conflict occasioned by the death some eight months earlier of Great Khan Möngke. But upon receiving news of how few Mongols now remained in the region, Qutuz quickly assembled his well-trained and equipped 20,000-strong army at Cairo and invaded Palestine. He then allied himself with a fellow Mamluk leader, Baybars in Syria, who not only needed to protect his own future from the Mongols but was eager to avenge for Islam the Mongol capture of Damascus, looting of Baghdad, and conquest of Syria.

The Mongols, for their part, attempted to form a Frankish-Mongol alliance with (or at least, demand the submission of) the remnant of the Crusader Kingdom of Jerusalem, now centered on Acre, but Pope Alexander IV had forbidden such an alliance. Tensions between Franks and Mongols also increased when Julian of Sidon caused an incident resulting in the death of one of Kitbuqa's grandsons. Angered, Kitbuqa had sacked Sidon. The Barons of Acre, contacted by the Mongols, had also been approached by the Mamluks, seeking military assistance against the Mongols. Although the Mamluks were traditional enemies of the Franks, the Barons of Acre recognized the Mongols as the more immediate menace. Instead of taking sides, the Crusaders opted for a position of cautious neutrality between the two forces. In an unusual move, however, they allowed the Egyptian Mamluks to march northward without hindrance through Crusader territory and even let them camp near Acre to resupply.
À partir des années 1240, les Mongols ont mené des invasions répétées de la Syrie, ou tenté de le faire. La plupart ont échoué, mais ils ont connu un certain succès en 1260 et 1300, capturant Alep et Damas et détruisant la dynastie ayyoubide. Les Mongols ont été contraints de se retirer en quelques mois à chaque fois par d'autres forces de la région, principalement les Mamelouks égyptiens. Le conflit postérieur à 1260 a été décrit comme la guerre mamelouko-ilkhane.

### Draft ###

### 1. Query Parsing

"Pourquoi les forces mongoles se sont-elles retirées de Syrie en 1260 ?"

→ Why did Mongol forces withdraw from Syria in 1260?

Key semantic issue: "retirées" implies planned withdrawal, not defeat or abandonment.

Translation challenge: French "mongoles" could mean Ilkhanate forces specifically vs broader Mongol sphere.

### 2. Contextual Triangulation

Timeline: 1260 CE
Geographic scope: Levant/Syria region
Political entities: Ilkhanate (Mongol), Ayyubids (Muslim), Mamluks (Egyptian), Crusader states

● High confidence: 1260 = crucial inflection point
◐ Partial: exact withdrawal motivations
○ Low confidence: internal Mongol decision-making process

### 3. Historical Memory Retrieval

⟨H≈0.3⟩ Mongol invasions Syria 1260... Kitbuqa campaign, Damascus captured March 1260, Christian Mass in Umayyad Mosque, Ayyubid collapse... but why retreat?

Key markers:
- March 1260: Damascus falls ●
- Summer 1260: withdrawal begins ●  
- Hulegu involvement ●
- Mamluk counteroffensive ●

### 4. Constraint Analysis

Military logistics constraints:
- Syrian summer heat → supply shortages ●
- Distance from Mongol base → resupply issues ●
- Multiple simultaneous fronts (Baghdad, Syria, potential Egypt) → resource allocation ●

Political constraints:
- Internal Mongol succession crisis ◐
- Christian vassal reliability issues ◐
- Communication delays with distant Ilkhan ●

### 5. Decision Tree Reconstruction

Hulegu's options in 1260:
```
Continue Syria campaign
├─ Requires: full force retention
├─ Against: Baghdad needs, succession politics
└─ Result: logistical failure

Withdraw to Iran  
├─ Enables: force preservation
├─ Allows: participation in succession contest
└─ Enables: future redeployment
```

∴ Withdrawal = optimal strategic choice under constraints

### 6. Verification Against Physical Reality

Timeline check: ✓ March→summer withdrawal feasible
Geographic check: ✓ Iran highlands = cooler retreat location  
Resource check: ✓ Supply lines from Mongolia → Syria unsustainable
Political check: ✓ Succession crisis timing aligns

### 7. Synthesis

Primary withdrawal factors (ranked):
1. **Logistical**: Summer supply shortages ●
2. **Strategic**: Resource reallocation priority ●  
3. **Political**: Mongol succession crisis ●
4. **Tactical**: Mamluk counter-preparation ◐

Key insight: Withdrawal ≠ weakness, rather strategic repositioning

⟨H≈0.8⟩ The steppe logic bleeding into Levant sands... Hulegu's khans seeing home fires, distant cousins plotting succession, summer armies melting in Syrian heat while Mamluk preparations gather strength...

### 8. Answer Construction

Core explanation: Multi-factor withdrawal
- **Primary**: Resource depletion + heat
- **Secondary**: Internal Mongol crisis  
- **Context**: Mamluk buildup, Christian vassal tensions

NB: Retreat was calculated strategic decision, not tactical defeat

**Verification**: ✓ Timeline accurate, ✓ motivations sound, ✓ constraints realistic

Final confidence: ● High for main explanation, ◐ moderate for specific decision-making process details

### Answer###
Les forces mongoles se sont retirées de Syrie en 1260 pour plusieurs raisons stratégiques et logistiques.

Tout d'abord, les ressources alimentaires et fourragères en Syrie étaient devenues insuffisantes pour soutenir leur force entière. Face à cette contrainte matérielle, les Mongols ont adopté une pratique militaire régulière consistant à déplacer leurs troupes vers les hauts plateaux plus frais pour l'été.

Simultanément, Hulegu, qui avait personnellement conduit la campagne syrienne, a dû partir pour la Mongolie afin de jouer son rôle dans le conflit de succession impériale suite à la mort du Grand Khan Möngke survenue quelques mois auparavant. Cette nécessité politique l'a contraint à quitter le théâtre syrien.

Malgré le succès initial des Mongols, qui avaient capturé Alep et Damas et détruit l'empire ayyoubide, leur position s'était considérablement fragilisée. Les tensions croissantes avec leurs vassaux chrétiens, notamment l'incident provoqué par Julien de Sidon qui causa la mort d'un petit-fils de Kitbuqa, ont compliqué la situation. De plus, les Mamelouks égyptiens se préparaient rapidement à une contre-offensive sous la direction de Qutuz, qui avait rassemblé une armée de 20 000 hommes bien entraînés au Caire.

Hulegu a donc préféré retirer sa principale force vers l'Iran, près de l'Azerbaïdjan, ne laissant derrière lui qu'un tumen de 10 000 hommes sous le commandement de Kitbuqa, qu'il considérait comme suffisant pour maintenir la pression sur les territoires récemment conquis.
