El Temür and the Merkit commander Bayan, a governor in Henan. This ended in the victory of Tugh Temür since he secured support from most of the princes, aristocrats and warlords in the south of the Gobi Desert. Tugh Temür summoned his brother to come to Dadu. At the same time, Kuśala, with support from the Chaghadayid leaders Eljigidey and Duwa Temür, entered Mongolia from the Tarbagatai region (in the Khangai Mountains). He also got support from princes and generals of Mongolia, and with overwhelming military power in the background, put pressure on Tugh Temür, who had already ascended the throne. Kuśala enthroned himself on 27 February 1329, north of Karakorum. Tugh Temür abdicated on 3 April 1329, and a month later El Temür brought the imperial seal to Kuśala in Mongolia, announcing Dadu's intent to welcome him. Kuśala responded by making Tugh Temür his heir apparent on 15 May. Kuśala had proceeded to appoint his own loyal followers to important posts in the Secretariat, the Bureau of Military Affairs, and the Censorate. Taking 1,800 men with him, Kuśala set out for Dadu. On 26 August, he met with Tugh Temür in Ongghuchad (Onggachatu), where Tugh Temur had built the city of Zhongdu. He suddenly died only 4 days after a banquet with Tugh Temür. The Yuan shi states that the luckless Kuśala Khan died of violence. It seems that Kuśala was poisoned by El Temür, who feared losing power to princes and officers of the Chagatai Khanate and Mongolia, who followed Kuśala. Tugh Temür was restored to the throne on 8 September. Family Khutughtu Khan had two wives who were Mailaiti, a descendant of the famous Qarluq chief, Arslan, who submitted to Genghis Khan and Babusha of the Naiman. They gave birth to two Mongol emperors, including Toghon Temür, the last Mongolian emperor to rule China.
