Emperor Duzong died in 1274 from overindulgence in wine. His sixth son, Zhao Xian, who was then about four years old, was enthroned as the new emperor with assistance from the chancellor Jia Sidao. In the following year, Zhao Xian's grandmother (Grand Empress Dowager Xie) and mother (Empress Dowager Quan) became regents for the child emperor, although state and military power remained under Jia Sidao's control.
