Abu Sa'id Bahadur Khan

Abu Sa'id Bahadur Khan (June 2, 1305 – December 1, 1335; ), also spelled Abusaid Bahador Khan, Abu Sa'id Behauder (Modern Абу Саид Бахадур хан, Abu sayid Baghatur Khan, in modern Mongolian), was the ninth ruler (c. 1316 – 1335) of the Ilkhanate, a division of the Mongol Empire that encompassed the present day countries of Iran, Azerbaijan, Georgia, and Armenia, as well as parts of Iraq, Turkey, Afghanistan, and Pakistan. After his death in 1335, the Ilkhanate disintegrated.

Early life
He was born on 2 June 1305, near Ujan, Tabriz to Öljaitü and Hajji Khatun. He became his father's heir after the deaths of his elder brothers. He was assigned to govern Khorasan and Mazandaran in 1315 with the Uyghur noble Amir Sevinch as his guardian.

Reign
He was brought back to Soltaniyeh by Sevinch in December, 1316. But his coronation was delayed until April, May, July or August 1317 due to a conflict between Chupan and Sevinch. Abu Said employed Rashid-al-Din Hamadani and Taj Al-Din Ali Shah Gilani as his viziers. However, the viziers were at odds and it led to Hamadani's dismissal in October 1317. Amir Sevinch also died in January 1318, leaving young Abu Sa'id in the hands of Chupan. Although Chupan recalled Hamadani to serve in court, Gilani accused Hamadani (and his son Ibrahim Izzaddin, the cupbearer) of poisoning the late Ilkhan Öljaitü, which led to their eventual execution on 13 July 1318 near Abhar. This left the emir Chupan as the de facto ruler of Ilkhanate, but the following years were tumultuous for Abu Sa'id's reign.

Golden Horde invasion and rebellion of amirs
Golden Horde khan Özbeg invaded Azerbaijan in 1319 in coordination with Chagatayid prince Yasa'ur who had pledged loyalty to Öljaitü earlier but revolted in 1319. Prior to that, he had Amir Yasaul, governor of Mazandaran killed by his subordinate Begtüt. Abu Sa'id was forced to send Amir Husayn Jalayir to face Yasa'ur while he himself marched against Özbeg. Özbeg was defeated shortly after thanks to reinforcements by Chupan, while Yasa'ur was killed by Kebek in 1320. Several amirs didn't come to the aid of Abu Sa'id, therefore they were subject to punishment by Chupan. Yet another revolt started in 1319, this time by Keraite emirs Irinjin, a former governor of Diyar Bakr and Qurumishi, governor of Georgia who were among the amirs rebuked by Chupan. Qurumishi and Irinjin were related in addition to both being from the Keraite tribe - Irinjin was the father of Öljaitü's widow Qutluqshah Khatun and a son-in-law to Tekuder, while Qurumshi's father Alinaq Noyan was also a son-in-law of Tekuder. A 40.000 strong rebel army caught Chupan with his two sons and 2000 strong entourage unguarded near Georgia and caused him to flee. Chupan arrived in Tabriz and later went to Abu Sa'id to report. Hearing this news, the Ilkhan moved against rebels and met them near Mianeh.

A decisive battle was fought on 20 June 1319 near Mianeh with an Ilkhanate victory. This victory granted young Abu Sa'id the honorific titles of Baghatur (from Mongolian "баатар", meaning "hero, warrior") and al-Sultan al-Adil (the just Sultan). In total 36 emirs and 7 khatuns, including Amir Toqmaq, Qurumishi, Princess Könchek (daughter of Tekuder), her husband Irinjin and their sons Sheykh Ali and Vafadar were executed while Qurumushi's son Abdurrahman fled to Özbeg. Chupan subsequently was given hand of Sati Beg, sister of Abu Sa'id on 6 September 1319, thus growing his family's power greatly. His sons Timurtash, Shaikh Mahmud, Hasan and Demasq Kaja were given governorships of Anatolia, Georgia, Khorasan and Azerbaijan respectively.

Chupanid rebellion
However, Timurtash rose in rebellion in 1322, claiming to be the Mahdi. Chupan went to obtain his surrender personally and even managed to get his reappointment to the post by Abu Sa'id. Abu Sa'id sometime fell in love with Baghdad Khatun, one of emir Chupan's daughters. The emir's efforts to keep Abu Sa'id from marrying his daughter, who was still married to Hasan Buzurg (another powerful kingmaker of the era), did not help the situation. Abu Said approached Chupan in 1325, claiming her unsuccessfully. Chupan sent his daughter and son-in-law to Karabakh instead while himself went against Özbeg and Tarmashirin who invaded Azerbaijan and Khorasan respectively. Using this opportunity, on 25 August 1327, Abu Sa'id had one of Chupan's sons, Demasq Kaja, killed, apparently for his activities with one of Öljaitü's former concubines. Hearing this, Chupan marched against Abu Sa'id seeking revenge. But many emirs including Muhammad Beg, uncle of Abu Sa'id deserted him near Ray, taking 30.000 soldiers with them, leaving Chupan no choice but to retreat to Herat. However he was soon strangled by Kartid ruler Ghiyath-uddin under orders of Abu Sa'id in 1327. His daughter was soon forced to divorce Hasan Buzurg and marry Abu Sa'id. In compensation, Hasan was awarded Chupan former post, rising to be a new commander-in-chief of the Ilkhanid army.

Later years
Now ruling personally, Abu Sa'id invited Ghiyas al-Din, son of Rashid al-Din to be his vizier. Narin Taghai (a nephew of Taghachar and grandson of Kitbuqa ) who was responsible for Chupan's downfall and Abu Sa'id's uncle Ali Padshah were granted governorates of Khorasan and Baghdad respectively. However Ghiyas al-Din's enforcement of central authority didn't coincide with other amirs' plans. Narin Taghai left his post in 1329 to kill Ghiyas al-Din. He was aided by emirs Ali Padshah and Misr Khwaja. Narin Taghay was executed in September or 29 July 1329, ending another serious threat. Later Hasan Buzurg too was accused of treason with Baghdad Khatun in 1332 but reinstated as governor of Anatolia later. However, Abu Sa'id divorced Baghdad and married her niece Dilshad Khatun in 1333.

In 1334, Abu Sa'id appointed Amir Musaffar Inaq as governor of Shiraz to the resentment of Sharaf al-Din Mahmudshah Inju, founder of Injuid dynasty, who was ruling Fars region for a while since Chupan's death. He pursued Musaffar to Abu Sa'id's tent, accidentally making attempt on his life. Mahmudshah's rebellious act got him imprisoned.

Foreign relations
Abu Sa'id signed a commercial treaty with Venice in 1320, while also granting them to establish oratories throughout the empire. He also improved relations with Mamluk Egypt the same year, signing a treaty. He is also known to have corresponded with Muhammad b. Tughluq of Delhi Sultanate.

Death
Abu Sa'id had to face another invasion by Özbeg in 1335 and left to face him, but died on his way in Karabakh, on the night of 30 November to 1 December 1335. His body was taken to Soltaniyeh and buried there. According to Ibn Battuta, he was poisoned by Baghdad Khatun on the grounds of jealousy. He might have been a victim of bubonic plague instead.

Abu Sa'id died without an heir or an appointed successor, thus leaving the Ilkhanate vulnerable. This led to clashes between the major families, such as the Chupanids, the Jalayirids, and new movements like the Sarbadars. On his return to Persia, the great voyager Ibn Battuta was amazed to discover that the realm which had seemed to be so mighty only twenty years before, had dissolved so quickly. The Ilkhanate lost cohesion after the death of Abu Sa'id, and that of his successor, Arpa Ke'un, becoming a plethora of little kingdoms run by Mongols, Turks, and Persians.
