When Yesun Temur died in Shangdu in 1328, Tugh Temur was recalled to Khanbaliq by the Qipchaq commander El Temur. He was installed as the emperor (Emperor Wenzong) in Khanbaliq, while Yesun Temur's son Ragibagh succeeded to the throne in Shangdu with the support of Yesun Temur's favorite retainer Dawlat Shah. Gaining support from princes and officers in Northern China and some other parts of the dynasty, Khanbaliq-based Tugh Temur eventually won the civil war against Ragibagh known as the War of the Two Capitals. Afterwards, Tugh Temur abdicated in favour of his brother Kusala, who was backed by Chagatai Khan Eljigidey, and announced Khanbaliq's intent to welcome him. However, Kusala suddenly died only four days after a banquet with Tugh Temur. He was supposedly killed with poison by El Temur, and Tugh Temur then remounted the throne. Tugh Temur also managed to send delegates to the western Mongol khanates such as Golden Horde and Ilkhanate to be accepted as the suzerain of Mongol world. However, he was mainly a puppet of the powerful official El Temur during his latter three-year reign. El Temur purged pro-Kusala officials and brought power to warlords, whose despotic rule clearly marked the decline of the dynasty.
