Although Tugh Temür Khan had a son named El Tegüs when he died in 1332, his widow and El Tegüs's mother Budashiri Khatun respected Tugh Temür's will of making Kuśala's son succeed the throne instead of El Tegüs.
The de facto ruler El Temür resisted letting Kuśala's eldest son Toghun Temür accede to the throne since he was suspected of having poisoned his father Kuśala. While Toghun Temür was kept far away from the capital Dadu, infant Rinchinbal was in Dadu and had became favored by Tugh Temür.
