Guo Wei (Chinese: 郭威) (10 September 904 – 22 February 954), also known by his temple name as the Emperor Taizu of Later Zhou (後周太祖), was the founding emperor of the Chinese Later Zhou dynasty during the Five Dynasties and Ten Kingdoms period, reigning from 951 until his death in 954.
Nicknamed "Sparrow Guo" (郭雀兒) after a sparrow-shaped tattoo on his neck, he rose to a high position in the Later Han as an assistant military commissioner. He founded the Later Zhou in 951.
Zhou, known as the Later Zhou (/dʒoʊ/; simplified Chinese: 后周; traditional Chinese: 後周; pinyin: Hòu Zhōu) in historiography, was a short-lived Chinese imperial dynasty and the last of the Five Dynasties that controlled most of northern China during the Five Dynasties and Ten Kingdoms period. Founded by Guo Wei (Emperor Taizu), it was preceded by the Later Han dynasty and succeeded by the Northern Song dynasty.
Chai Rong (Chinese: 柴榮) (27 October 921 – 27 July 959), later known as Guo Rong (郭榮), also known by his temple name as the Emperor Shizong of Later Zhou, was the second emperor of the Later Zhou dynasty of China, during the Five Dynasties and Ten Kingdoms period. He reigned from 954 until his death in 959. He succeeded his uncle-in-law Guo Wei (Emperor Taizu), whose surname he had adopted.
Emperor Shizong is considered a highly successful emperor of the Five Dynasties period. He centralized military power by his reforms, and proved his military prowess by a series of victories against Northern Han, Later Shu, Southern Tang, and the Liao dynasty. Although his accomplishments were limited due to his premature death, they paved the way for the eventual unification of large parts of China proper by the Northern Song, founded by his trusted generals Zhao Kuangyin and Zhao Guangyi.
