About Emperor Gongdi of Later Zhou

Guo Zongxun or Chai Zongxun, also known by his posthumous name as the Emperor Gong of Later Zhou, was the third and last emperor of the Later Zhou dynasty during the Five Dynasties and Ten Kingdoms period. As the only child of Guo Rong, he ascended the throne in July 959, when his father suddenly died of illness during a northern military expedition attempting to recapture the Sixteen Prefectures from the Khitans Liao dynasty. His reign ended just months later in February 960, when the six-year-old emperor was usurped in a mutiny led by royal guard general Zhao Kuangyin, who founded the Song dynasty.
