After his father's execution, Qurumushi inherited Alinaq's domains in modern Javakheti, his mingghan and his wife Kuchuk Khatun in levirate.
Around 1299 Ghazan became suspicious of the reports that David VIII and Toqta Khan of Golden Horde were preparing for an alliance.
David refused to comply and Ghazan Khan responded with a punitive expedition under Qurumushi, Alinji and Shahinshah.
Supported by the Mongols, Ossetes attacked Shida Kartli province and occupied the Liakhvi River gorge.
[6] However, Abu Sa'id caught off-guard when both Öz Beg Khan and Yasa'ur invaded Ilkhanate in Golden Horde-Chagatai alliance, 1319.
Chupan summoned his subordinate emirs, including Qurumshi and caught up to Abu Sa'id and defeated the Ozbeg on the shores of Kura river.
[7] When Abu Sa'id left for his capital Qurumushi attacked his camp led by Toqmaq noyan, forced him to change sides.
Abu Sa'id's army were commanded by Taz, son of Kitbuqa and Mamluk renegade Qara Sonqur.
[10] During trial Qurumushi said that the rebellion was in fact against Chupan and was authorized by Abu Sa'id himself who sent him two envoys - Yusuf Böke and Harza Muhammad of Suldus.
Irinjin in his defence showed a yarligh given to him by the ilkhan, authorizing him to act against Chupan; a document with Abu Sa'id denied again.
