Nawrūz (Persian: نوروز; died 13 August 1297) was a son of governor Arghun Aqa and a powerful 13th-century Oirat emir who played an important role in the politics of the Mongol Ilkhanate.
[6] He soon abandoned Kaidu as well, this time allying himself with Kadan's grandson Ürük Temür, giving his daughter to him in marriage and sponsoring his conversion to Islam.
Managing to gain the loyalty of emirs like Taghachar, Chupan, Irinjin and Qurumushi, Nawruz ensured Ghazan's victory over Baydu in 1295.
As a fervent adherent to Islam;[9] the history of Bar Sawma's voyages and Mar Yaballaha III's Patriarchal tenure portrays him as a ferocious enemy of Nestorian Christians.
However the Ilkhanid prince Sogai (son of Yoshmut) refused to join the campaign in Khorasan, believing this was a plot of Nawruz to further deprive nobility of their possessions.
After returning West, he survived an assassination attempt by a soldier named Tuqtay, who claimed that Nawruz murdered his own father, Arghun Aqa.
His 12-year-old son Toghai was spared due to the efforts of Bulughan Khatun Khurasani, Ghazan's wife Arghun Aqa's granddaughter and given to the household of Amir Husayn.
Following these defeats, Nawrūz took refuge at the court of the malik Fakhr al-Din of Herat, in northern Afghanistan, but the latter betrayed him and delivered him to Qutluqshah, who had him executed immediately on 13 August 1297,[11][12] along with his brothers Hajji and Bulquq.
