Who is Duwa Temür?
He surrendered to the Yuan army in 1313 when Esen Buqa I revolted against Ayurbarwada Khagan whom he had paid tributes before. Duwa Temür became khan by overthrowing his brother Eljigidey. Some Muslim sources claim that he himself was removed by power by another brother, Tarmashirin, who then took control of the Chagatai ulus after only a short period of time. But it is known that he was still the ruler of the Chagatayids in 1330 from the History of the Yuan Dynasty and some European sources. Because Tarmashirin wrote in his letter that he enthroned as Chagatai Khan in 1330 to the Yuan Dynasty and the map published in China in around 1330 also shows the Chagatai Khanate as the Ulus of Duwa Temur.
