Hulagu (1256–1265) Hulagu Khan, a grandson of Genghis Khan, was an avowed
shamanist, but was nevertheless very tolerant of Christianity. His mother
Sorghaghtani Beki, his favorite wife
Doquz Khatun, and several of his closest collaborators were Nestorian Christians. One of his most important generals,
Kitbuqa, was a Nestorian Christian of the Naiman tribe. For Asiatic Christians, the fall of Baghdad was cause for celebration. Hulagu and his Christian queen came to be considered as God's agents against the enemies of Christianity, and were compared to the influential 4th-century Christian Emperor
Constantine the Great and his revered mother,
Empress Helena, an icon of the Christian church. The Armenian historian
Kyrakos of Gandzak praised the Mongol royal couple in texts for the
Armenian Church, and
Bar Hebraeus, a bishop of the
Syriac Orthodox Church, also referred to them as a Constantine and Helena, writing of Hulagu that nothing could compare to the "king of kings" in "wisdom, high-mindedness, and splendid deeds".
Invasion of Syria (1260) After Baghdad, in 1260 the Mongols with their Christian subjects conquered Muslim
Syria, domain of the Ayyubid dynasty. They took together the city of
Aleppo in January, and in March, the Mongols with the Armenians and the Franks of Antioch took
Damascus, under the Christian Mongol general Kitbuqa. The last Ayyubid sultan
An-Nasir Yusuf died shortly thereafter, and with the Islamic power centers of Baghdad and Damascus gone, the center of Islamic power transferred to the Egyptian Mamluks in Cairo. However, before the Mongols could continue their advance towards Egypt, they needed to withdraw because of the death of the Great Khan. Hulagu was needed back at the capital and took the bulk of his forces with him, leaving a small force under Kitbuqa to occupy Palestine during his absence.
Mongol raiding parties were sent south into Palestine towards Egypt, with small Mongol garrisons of about 1,000 established in Gaza.
Battle of Ain Jalut Despite the cooperation between the Mongols and their Christian subjects in Antioch, other Christians in the Levant regarded the Mongol approach with unease. Jacques Pantaléon, the Patriarch of Jerusalem, saw the Mongols as a clear threat, and had written to the Pope to warn him about them in 1256. The Franks did, however, send the Dominican
David of Ashby to the court of Hulagu in 1260. The Franks of Acre did their best to maintain a position of cautious neutrality between the Mongols and the Mamluks. Despite their long history of enmity with the Mamluks, the Franks acknowledged that the Mongols were a greater threat, and after careful debate, chose to enter into a passive truce with their previous adversaries. The Franks allowed the Mamluk forces to move northward through Christian territory to engage the Mongols, in exchange for an agreement that the Franks could purchase any captured Mongol horses at a low price. The truce allowed the Mamluks to camp and re-supply near Acre, and engage the Mongols at Ain Jalut on . The Mongol forces were already depleted due to their main force withdrawing, so with the passive assistance of the Franks, the Mamluks were able to achieve a decisive and historic victory over the Mongols. The remainder of the Mongol army retreated to Cilician Armenia, where they were received and re-equipped by Hethum I. As recently as 1259,
Pope Alexander IV had been encouraging a new crusade against the Mongols, and had been extremely disappointed in hearing that the monarchs of Antioch and Armenia had submitted to Mongol overlordship. Alexander had put the monarchs' cases on the agenda of his upcoming council, but died in 1261 just months before the council could be convened, and before the new crusade could be launched. For a new pope, the choice fell to Pantaléon, the same Patriarch of Jerusalem who had earlier been warning of the Mongol threat. He took the name Pope Urban IV, and tried to raise money for a new crusade. On , the Mongol leader Hulagu sent through
John the Hungarian a new letter to King Louis IX of France, again offering an alliance. The letter explained that previously, the Mongols had been under the impression that the pope was the leader of the Christians, but now they realized that the true power rested with the French monarchy. The letter mentioned Hulagu's intention to capture Jerusalem for the benefit of the pope, and asked for Louis to send a fleet against Egypt. Hulagu promised the restoration of Jerusalem to the Christians, but also still insisted on Mongol sovereignty, in the Mongols' quest for conquering the world. It is unclear whether or not King Louis actually received the letter, but at some point it was transmitted to Pope Urban, who answered in a similar way as his predecessors. In his papal bull
Exultavit cor nostrum, Urban congratulated Hulagu on his expression of goodwill towards the Christian faith, and encouraged him to convert to Christianity. Historians dispute the exact meaning of Urban's actions. The mainstream view, exemplified by British historian
Peter Jackson, holds that Urban still regarded the Mongols as enemies at this time. This perception began changing a few years later, during the pontificate of
Pope Clement IV (1265–68), when the Mongols were seen more as potential allies. However, the French historian
Jean Richard argues that Urban's act signaled a turning point in Mongol-European relations as early as 1263, after which the Mongols were considered as actual allies. Richard also argues that it was in response to this forming coalition between the Franks, Ilkhanid Mongols and Byzantines, that the Mongols of the Golden Horde allied with the Muslim Mamluks in return. However, the mainstream view of historians is that though there were many attempts at forming an alliance, the attempts proved unsuccessful. Abaqa corresponded with Pope Clement IV through 1267 and 1268, sending envoys to both Clement and King
James I of Aragon. In a 1268 message to Clement, Abaqa promised to send troops to aid the Christians. It is unclear if this was what led to James's
unsuccessful expedition to Acre in 1269. Abaqa, despite his earlier promises of assistance, was in the process of facing another threat, an invasion in
Khorasan by Mongols from
Turkestan, and so could only commit a small force for the Holy Land, which did little but brandish the threat of an invasion along the Syrian frontier in October 1269. He raided as far as
Harim and
Afamiyaa in October, but retreated as soon as Baibars' forces advanced. The number of knights and retainers that accompanied Edward on the crusade was quite small, possibly around 230 knights, with a total complement of approximately 1,000 people, transported in a flotilla of 13 ships. Edward understood the value of an alliance with the Mongols, and upon his arrival in Acre on , he immediately sent an embassy to the Mongol ruler Abaqa, requesting assistance. Abaqa answered positively to Edward's request, asking him to coordinate his activities with his general
Samagar, whom he sent on an offensive against the Mamluks with 10,000 Mongols to join Edward's army. But Edward was able only to engage in some fairly ineffectual raids that did not actually achieve success in gaining new territory. Edward's efforts were described by historian Reuven Amitai as "the nearest thing to real Mongol-Frankish military coordination that was ever to be achieved, by Edward or any other Frankish leader."
Council of Lyon (1274) In 1274
Pope Gregory X convened the
Second Council of Lyon. Abaqa sent a delegation of 13 to 16 Mongols to the council, which created a great stir, particularly when three of their members underwent a public
baptism. Abaqa's Latin secretary
Rychaldus delivered a report to the Council which outlined previous European-Ilkhanid relations under Abaqa's father, Hulagu, affirming that after Hulagu had welcomed Christian ambassadors to his court, he had agreed to exempt Latin Christians from taxes and charges, in exchange for their prayers for the Khan. According to Rychaldus, Hulagu had also prohibited the molestation of Frank establishments, and had committed to return Jerusalem to the Franks. Rychaldus assured the assembly that even after Hulagu's death, his son Abaqa was still determined to drive the Mamluks from Syria. Abaqa then sent another embassy, led by the Georgian Vassali brothers, to further notify Western leaders of military preparations. Gregory answered that his
legates would accompany the crusade, and that they would be in charge of coordinating military operations with the Ilkhan. However, the papal plans were not supported by the other European monarchs, who had lost enthusiasm for the Crusades. Only one western monarch attended the council, the elderly James I of Aragon, who could only offer a small force. There was fundraising for a new crusade, and plans were made, but never followed through. The projects essentially came to a halt with the death of Pope Gregory on , and the money which had been raised to finance the expedition was instead distributed in Italy.
Invasion of Syria (1280–1281) Without support from the Europeans, some Franks in
Outremer, particularly the
Knights Hospitaller of the fortress of
Marqab, and to some extent the Franks of Cyprus and Antioch, attempted to join in combined operations with the Mongols in 1280–1281. He also renewed a second 10-year truce with Bohemond VII of Tripoli on , and affirmed pilgrim access to Jerusalem. In retaliation, Qalawun later besieged and captured the Hospitaller fortress of Marqab in 1285. Abaqa died in 1282 and was briefly replaced by his brother
Tekuder, who had converted to Islam. Tekuder reversed Abaqa's policy of seeking an alliance with the Franks, offering instead an alliance to the Mamluk Sultan Qalawun, who continued his own advance, capturing the Hospitaller fortress of Margat in 1285,
Lattakia in 1287, and the County of Tripoli in 1289. The embassy was sent because the Great Khan Kublai (Qubilai) ordered Arghun to free Holy Land and protect Christians. Kelemechi met with
Pope Honorius IV in 1285, offering to "remove" the
Saracens (Muslims) and divide "the land of Sham, namely Egypt" with the Franks. The second embassy, and probably the most famous, was that of the elderly cleric
Rabban Bar Sauma, who had been visiting the Ilkhanate during a remarkable pilgrimage from China to Jerusalem. Bar Sauma was greeted warmly by the European monarchs, England did respond by sending a representative,
Geoffrey of Langley, who had been a member of Edward I's Crusade 20 years earlier, and was sent to the Mongol court as an ambassador in 1291.
Genoese shipmakers Another link between Europe and the Mongols was attempted in 1290, when the
Genoese endeavored to assist the Mongols with naval operations. The plan was to construct and man two galleys to attack Mamluk ships in the
Red Sea, and operate a blockade of Egypt's trade with India. Genoa finally cancelled the agreement and signed a new treaty with the Mamluks instead.
Ghazan (1295–1304) After Arghun's death, he was followed in rapid succession by two brief and fairly ineffective leaders, one of whom only held power for a few months. Stability was restored when Arghun's son Ghazan took power in 1295, though to secure cooperation from other influential Mongols, he made a public conversion to Islam when he took the throne, marking a major turning point in the state religion of the Ilkhanate. Despite being an official Muslim, however, Ghazan remained tolerant of multiple religions, and worked to maintain good relations with his Christian vassal states such as Cilician Armenia and Georgia. In 1299, he made the first of what were to be three attempts to invade Syria. As he launched his new invasion, he also sent letters to the Franks of Cyprus (
Henry II, King of Cyprus; and the heads of the
military orders), inviting them to come join him in his attack on the Mamluks in Syria. This success in Syria led to wild rumors in Europe that the Mongols had successfully re-captured the Holy Land, and had even conquered the Mamluks in Egypt and were on a mission to conquer Tunisia in northern Africa. But in reality, Jerusalem had been neither taken nor even besieged. All that had been managed were some Mongol raids into Palestine in early 1300. The raids went as far as Gaza, passing through several towns, probably including Jerusalem. But when the Egyptians again advanced from Cairo in May, the Mongols retreated without resistance. A fleet of sixteen galleys with some smaller vessels was equipped in Cyprus, commanded by King Henry of Cyprus, accompanied by his brother
Amalric, Lord of Tyre, the heads of the military orders, and Ghazan's ambassador "Chial" (
Isol the Pisan). The ships left
Famagusta on , to raid the coasts of Egypt and Syria:
Rosette,
Alexandria, Acre, Tortosa, and
Maraclea, before returning to Cyprus. They prepared the largest force they could muster at the time, approximately 600 men: 300 under Amalric, and similar contingents from the Templars and Hospitallers. In November 1300 they attempted to occupy Tortosa on the mainland, but were unable to gain control of the city. The Mongols were delayed, and the Cypriots moved offshore to the nearby island of Ruad to establish a base. Plans for combined operations between the Franks and the Mongols were again made for the following winter offensives, in 1301 and 1302. But in mid-1301 the island of Ruad was attacked by the Egyptian Mamluks. After a lengthy siege, the island surrendered in 1302. In 1303, Ghazan sent another letter to Edward I, via Buscarello de Ghizolfi, who had also been an ambassador for Arghun. The letter reiterated their ancestor Hulagu's promise that the Ilkhans would give Jerusalem to the Franks in exchange for help against the Mamluks. That year, the Mongols again attempted to invade Syria, appearing in great strength (about 80,000) together with the Armenians. But they were again defeated at Homs on , and at the decisive
Battle of Shaqhab, south of Damascus, on . Ghazan died on , and Frankish dreams of a rapid reconquest of the Holy Land were destroyed.
Oljeitu (1304–1316) Oljeitu, also named Mohammad Khodabandeh, was great-grandson of Ilkhanate founder Hulagu, and brother and successor of Ghazan. In his youth he at first converted to Buddhism, and then later to Sunni Islam with his brother Ghazan, and changed his first name to the Islamic
Muhammad. In April 1305, Oljeitu sent letters to
Philip IV of France,
Pope Clement V, and Edward I of England. As had his predecessors, Oljeitu offered a military collaboration between the Mongols and the Christian states of Europe, against the Mamluks. Various European states prepared a crusade, but were delayed. In the meantime Oljeitu launched a last campaign against the Mamluks (1312–1313), in which he was unsuccessful. A final settlement with the Mamluks would only be found when Oljeitu's son
Abu Sa'id signed the
Treaty of Aleppo in 1322. == Last contacts ==
