Esen Buqa I

Esen Buqa I (died c. 1318), a son of Duwa, spent his early years at the Yuan capital of Dadu. After his brother Kebek overthrew Taliqu in 1308 or 1309, a quriltai in 1310 proclaimed him Chagatai khan.

He began on good terms with the Yuan and sent tribute, but border quarrels brought war in 1314 with both the Yuan and the Ilkhan. Yuan forces defeated him in 1315, and he died around 1318, after which Kebek returned to the throne.
