# Öljaitü

Öljaitü, also known as Mohammad-e Khodabandeh (24 March 1282 – 16 December 1316), was the eighth Ilkhanid dynasty ruler from 1304 to 1316 in Tabriz, Iran. His name 'Öjaitü' means 'blessed' in the Mongolian language and his last name 'Khodabandeh' means 'God's servant' in the Persian language.
He was the son of the Ilkhan ruler Arghun, brother and successor of Mahmud Ghazan (5th successor of Genghis Khan), and great-grandson of the Ilkhanate founder Hulagu.

## Early life

Öljaitü was born to Arghun and his third wife, Keraite Christian Uruk Khatun on 24 March 1282 during his father's viceroyalty in Khorasan. He was given the name Khar-banda (mule driver) at birth, raised as Buddhist and later baptised in 1291, receiving the name Nikolya (Nicholas) after Pope Nicholas IV. However, according to Tarikh-i Uljaytu (History of Oljeitu), Öljeitu was at first known as "Öljei Buqa", and then "Temüder", and finally "Kharbanda". Various c. Same source also mentions that it rained when he was born, and the delighted Mongols called him by the Mongolian name Öljeitu (Өлзийт), meaning auspicious. He was later converted to Sunni Islam along with his brother Ghazan. Like his brother, he changed his first name to the Islamic name Muhammad.
He participated in battles involving Ghazan's fight against Baydu. After his brother Ghazan's accession to throne, he was appointed as viceroy of Khorasan. Despite being appointed heir of Ghazan since 1299, after hearing news of his death he sought to eliminate potential rivals to throne. First such act was taken against Prince Alafrang, son of Gaykhatu. He was killed by an emissary of Öljaitü on 30 May 1304. Another powerful emir, Horqudaq was likewise captured and executed.

## Reign

He arrived in the Ujan plain on 9 July 1304 and was crowned on 19 July 1304. Rashid al-Din wrote that he adopted the name Oljeitu following Yuan emperor Öljeitu Temür enthroned in Dadu. His full regnal title was Ghiyath al-Din Muhammad Khudabanda Öljaitü Sultan. Upon accession, he made several appointments, such Qutluqshah to the post of commander-in-chief of Ilkhanate army, Rashid al-Din and Sa'd al-Din Savaji as his viziers on 22 July 1304. Another appointment was Asil al-Din, son of Nasir al-Din Tusi as his father's successor to head Maragheh observatory. Another political decision was revoking Kerman from Qutluqkhanid Qutb al-Din Shah Jahan on 21 April 1304. Öljaitü appointed his father-in-law and uncle Irinjin as viceroy of Anatolia on 27 June 1305.
He received ambassadors from the Yuan dynasty (19 September 1305), Chagatai Khanate (in persons of Chapar, son of Kaidu and Duwa, son of Baraq) and Golden Horde (8 December 1305) in the same year, establishing an intra-Mongol peace. His reign also saw a wave of migration from Central Asia during 1306. Certain Borjigid princes, such as Mingqan Ke'un (grandson of Ariq Böke and grandfather of future Arpa Ke'un), Sarban (son of Kaidu), Temür (a descendant of Jochi Qasar) arrived in Khorasan with 30.000 or 50.000 followers.
He undertook an expedition to Herat against the Kartid ruler Fakhr al-Din in 1306, but succeeded only briefly; his emir Danishmend was killed during the ambush. He started his second military campaign in June 1307 towards Gilan. It was a success thanks to combines forces of emirs like Sutai, Esen Qutluq, Irinjin, Sevinch, Chupan, Toghan and Mu'min. Despite initial success, his commander-in-chief Qutluqshah was defeated and killed during the campaign, which paved way for Chupan to rise in ranks. Following this, he ordered another campaign against Kartids, this time commanded by the late emir Danishmend's son Bujai. Bujai was successful after a siege from 5 February to 24 June 1306, finally capturing the citadel. A corps of Frankish mangonel specialists is known to have accompanied the Ilkhanid army in this conquest.
Another important event of 1307 was the completion of the Jami al-Tawarikh by Rashid al-Din on 14 April 1307. Later in 1307, a revolt broke in Kurdistan under the leadership of certain Musa, who claimed to be the Mahdi. The uprising was swiftly defeated. Another religious revolt, this time by 10.000 strong Christians, broke out in Irbil. Despite Mar Yahballaha's best efforts to avert the impending doom, the citadel was at last taken after a siege by Ilkhanate troops and Kurdish tribesmen on 1 July 1310, and all the defenders were massacred, including many of the Assyrian inhabitants of the lower town.
An important change in administration happened in 1312 when Öljaitü's vizier Sa'd al-Din Savaji was arrested on charges of corruption and executed on 20 February 1312. He was soon replaced by Taj al-Din Ali Shah, who would head the Ilkhanate civil administration until 1323. Another victim of the purge was Taj al-Din Avaji, a follower of Sa'd al-Din. Öljaitü also finally launched a last campaign against the Mamluks, in which he was unsuccessful, though he reportedly briefly took Damascus. It was when Mamluk emirs, former governor of Aleppo—Shams al-Din Qara Sonqur and governor of Tripoli—al-Afram defected to Öljaitü. Despite extradition requests from Egypt, Ilkhan invested Qara Sonqur (now under the new name Aq Sonqur) with the governorate of Maragheh and al-Afram with Hamadan. Qara Sonqur was later given Oljath—daughter of Abaqa Khan on 17 January 1314.
Meanwhile, relations between other Mongol realms were getting heated. The new khan of Golden Horde, Ozbeg sent an emissary to Öljaitü, renewing his claims to Azerbaijan on 13 October 1312. Öljaitü also supported the latter during Chagatai-Yuan war in 1314, annexing Southern Afghanistan after expelling Qara'unas. After repelling Chagatai armies, he appointed his son Abu Sa'id to govern Khorasan and Mazandaran in 1315 with the Uyghur noble Amir Sevinch as his guardian. Another descendant of Jochi Qasar, Baba Oghul arrived from Central Asia in the same year, pillaging Khwarazm on his way, causing much disturbance. Upon protests from Golden Horde emissaries, Öljaitü had to execute Baba, claiming he was not informed of such unauthorized acts.
Öljaitü's reign is also remembered for a brief effort at Ilkhanid invasion of Hijaz. Humaydah ibn Abi Numayy, arrived at the Ilkhanate court in 1315, Ilkhan on his part provided Humaydah an army of several thousand Mongols and Arabs under the command of Sayyid Talib al-Dilqandi to bring the Hijaz under Ilkhanid control. He also planned to exhume the bodies of the caliphs Abu Bakr and Umar ( radiallahtaalaanhu ) from their graves in Medina. However, soon after the expedition passed Basra they received news of Ilkhan's death, and a large part of the army deserted. The remainder – three hundred Mongols and four hundred Arabs – were crushed by a horde of four thousand Bedouin led by Muhammad ibn Isa (brother of Muhanna ibn Isa) in March 1317.

## Death

He died in Soltaniyeh on 17 December 1316, having reigned for twelve years and nine months. Afterwards, Rashid al-Din Hamadani was accused of having caused his death by poisoning and was executed. Oljeitu was succeeded by his son Abu Sa'id.

## Religion

Öljaitü had been professing Buddhism, Christianity and Islam throughout his life. After succeeding his brother, Öljeitu became influenced by Shi'a theologians Al-Hilli and Maitham Al Bahrani. Although another source indicates he converted to Islam through the persuasions of his wife. Upon Al-Hilli's death, Oljeitu transferred his teacher's remains from Baghdad to a domed shrine he built in Soltaniyeh. Later, alienated by the factional strife between the Sunnis, Oljeitu changed his school of thought to Shi'a Islam in 1310. At some point, he even considered converting to Tengriism in early 1310. Mamluk historian al-Safadi mentioned in his biographical dictionary Aʻyan al-ʻAsr that Oljeitu had once again became Sunni in the last few years before his death in the Ramadan of 716 AH.

## Legacy

He oversaw the end of construction of city of Soltaniyeh on Qongqur-Oleng plains in 1306. In 1309, Öljeitu founded a Dar al-Sayyedah ("Sayyed's lodge") in Shiraz, Iran, and endowed it with an income of 10,000 dananeer a year. His tomb in Soltaniyeh, 300 km west of Tehran, remains the best known monument of Ilkhanid Persia. According to Ruy González de Clavijo, his body was later exhumed by Miran Shah.

## Relations with Europe
### Trade contacts

Trading contacts with European powers were very active during the reign of Öljeitu. The Genoese had first appeared in the capital of Tabriz in 1280, and they maintained a resident Consul by 1304. Oljeitu also gave full trading rights to the Venetians through a treaty in 1306 (another such treaty with his son Abu Said was signed in 1320). According to Marco Polo, Tabriz was specialized in the production of gold and silk, and Western merchants could purchase precious stones in quantities.

### Military alliance

After his predecessors Arghun and Ghazan, Öljeitu continued diplomatic overtures with the West, and re-stated Mongol hopes for an alliance between the Christian nations of Europe and the Mongols against the Mamluks, even though Öljeitu himself had converted to Islam.

#### 1305 embassy

In April 1305, he sent a Mongol embassy led by Buscarello de Ghizolfi to the French king Philip IV of France, Pope Clement V, and Edward I of England. The letter to Philip IV, the only one to have survived, describes the virtues of concord between the Mongols and the Franks:
   "We, Sultan Oljaitu. We speak. We, who by the strength of the Sky, rose to the throne (...), we, descendant of Genghis Khan (...). In truth, there cannot be anything better than concord. If anybody was not in concord with either you or ourselves, then we would defend ourselves together. Let the Sky decide!"
He also explained that internal conflicts between the Mongols were now over:
   "Now all of us, Timur Khagan, Tchapar, Toctoga, Togba and ourselves, main descendants of Gengis-Khan, all of us, descendants and brothers, are reconciled through the inspiration and the help of God. So that, from Nangkiyan (China) in the Orient, to Lake Dala our people are united and the roads are open."
This message reassured the European nations that the Franco-Mongol alliance, or at least attempts towards such an alliance, had not ceased, even though the Khans had converted to Islam.

#### 1307 embassy

Another embassy was sent to the West in 1307, led by Tommaso Ugi di Siena, an Italian described as Öljeitu's ildüchi ("Sword-bearer"). This embassy encouraged Pope Clement V to speak in 1307 of the strong possibility that the Mongols could remit the Holy Land to the Christians, and to declare that the Mongol embassy from Öljeitu "cheered him like spiritual sustenance". Relations were quite warm: in 1307, the Pope named John of Montecorvino the first Archbishop of Khanbalik and Patriarch of the Orient.
European nations accordingly prepared a crusade, but were delayed. A memorandum drafted by the Grand Master of the Knights Hospitallers Guillaume de Villaret about military plans for a Crusade envisaged a Mongol invasion of Syria as a preliminary to a Western intervention (1307/8).

#### Military operation 1308

Byzantine Emperor Andronicus II gave a daughter in marriage to Oljeitu and asked the Ilkhan's assistance against growing the power of the Ottomans. In 1305, Oljeitu promised his father in law 40,000 men, and in 1308 dispatched 30,000 men to recover many Byzantine towns in Bithynia and the Ilkhanid army crushed a detachment of Osman I.

#### 1313 embassy

On 4 April 1312, a Crusade was promulgated by Pope Clement V at the Council of Vienne. Another embassy was sent by Oljeitu to the West and to Edward II in 1313. That same year, the French king Philippe le Bel "took the cross", making the vow to go on a Crusade in the Levant, thus responding to Clement V's call for a Crusade. He was however warned against leaving by Enguerrand de Marigny, and died soon after in a hunting accident.
A final settlement with the Mamluks would only be found when Oljeitu's son signed the Treaty of Aleppo with the Mamluks in 1322.
