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 February 27, 1329, north of Karakorum.
