Jia Sidao
In 1274, Emperor Duzong died. His four-year-old son Zhao Xian was enthroned as Emperor Gong of Song with the assistance of chancellor Jia Sidao. The following year, Gong became regent under the regency of his adoptive grandmother, Grand Empress Dowager Xie (謝太皇太后) and, nominally, his mother Empress Dowager Quan (全太后).
