Irinjin's rivalry with Chupan, led to his adjoin of
Qurumushi, another Kerait emir and commander of Mongol garrison in
Georgia. Apart being both Keraites, Qurumushi and Irinjin were both related to il-khan
Tekuder by marriage. Qurumushi revolted after his rebuke by Chupan, because of him not coming to aid of Abu Sa'id against invasion of
Ozbeg of
Golden Horde. Chupan's subordinate Toqmaq also defected to rebel side, because of his old rivalry with
Demasq Kaja, son of Chupan. Irinjin's daughter Tursin's hand was sought by Toqmaq, but eventually was married to Demasq Khaja on the orders of
Öljaitü. Irinjin's son Shaykh Ali was Abu Sa'id's favorite and his falconer since his governorate in
Khorasan, which led some researchers to believe revolt was indeed orchestrated by Abu Sa'id himself who wanted to get rid of Chupan. Qurumushi's 40.000 strong rebel army caught Chupan with his two sons and 2000 strong entourage unguarded near
Georgia and caused him to flee, this was when Irinjin openly joined the revolt. When news of Chupan's defeat reached to
Soltaniyeh, Irinjin's son and daughter agreed to plunder the belongings of Demasq Kaja, but was prevented from killing him by Ögrünch, Uyghur emir. Irinjin on his part, pillaged Timurtash's belongings in Anatolia. Rebel armies merged near
Nakhchivan and set course to Abu Sa'id's main army soon later. Ilkhanate armies were commanded by Abu Sa'id himself on centre with Ögrünch and Chupan, while his
Oirat uncles
Ali Padshah and Muhammad was positioned on left wing. Right wing was commanded by Mahmud b. Esen Qutluq and Shayk Ali b. Ali Qushchi. On their part, Irinjin was commanding center on rebel side with his wife Princess Könchek, emir Toqmaq and his brother Aras were commanding left, while Qurumushi commanded right flank. A last second peace attempt by Qutluqshah, Irinjin's wife was in vain. A decisive battle was fought on 20 June 1319 near
Mianeh with Ilkhanate victory. Irinjin was captured in vicinity of Kaghazkunan, near
Khalkhal.
Aftermath During trial at Soltaniyeh, Irinjin claimed that he was acting on Abu Sa'id's orders, a claim he rejected. He was executed in Soltaniyeh with a skewer driven up from his chin to brain. Irinjin's body was displayed for 2–3 days and his severed head was sent around Ilkhanate provinces. His 15-year-old son Vafadar were also decapitated, while his wife Könchek was trampled to death by horses. In total 36 emirs and 7 khatuns were executed, including Amir Toqmaq, Qurumishi, Princess Könchek (daughter of
Tekuder) and Irinjin. Qutluqshah Khatun was spared and married off to Pulad Qiya, a brother of Amir Ordu Qiya. Shaykh Ali was already executed before battle. == Religion ==
