Shi Jingtang

Shi Jingtang (Chinese: 石敬瑭; 30 March 892 – 28 July 942), also known by his temple name as the Emperor Gaozu of Later Jin (後晉高祖), was the founding emperor of the Later Jin dynasty of China during the Five Dynasties and Ten Kingdoms period, reigning from 936 until his death.

Shi was an ethnic Shatuo and was an important military general for the Later Tang before rebelling in 936. He enlisted the help of the Khitan-led Liao dynasty in his struggle against the Later Tang dynasty. For this he was called Emperor Taizong of Liao's adopted son (even though he was 10 years older).

After Shi's rise to power, the Liao would later annex the strategically crucial Sixteen Prefectures and eventually annex the entire Later Jin. The rise of the Liao in northern China and the Mongolian Plateau would shape Chinese politics for the centuries leading up to the Mongol Empire.

The official history Old History of the Five Dynasties stated that his family was originally descended from Shi Que (石碏), an official of the Spring and Autumn period state Wey, through the Han prime minister Shi Fen (石奮), and further stated that Shi Fen's descendants fled west when Han fell, settling in what would eventually become Gan Prefecture (甘州, in modern Zhangye, Gansu), apparently in an attempt to try to link Shi with a Han Chinese ancestry despite the Shatuo origin. Under the Old History of the Five Dynasties account, his great-great-grandfather, whose name was given as Shi Jing (石璟), followed the Shatuo chieftain Zhuye Zhiyi (朱邪執宜) in submitting to Tang, and was settled, along with the rest of the Shatuo people under Zhuye, in Tang territory. Shi Jingtang's father Nieliji (臬捩雞), who was referred to by the Han Chinese name Shi Shaoyong (石紹雍), was said to be a successful general under Zhuye Zhiyi's grandson Li Keyong, who was an important late-Tang warlord, and Li Keyong's son Li Cunxu, who ruled the independent state of Jin after Tang's fall. The other official history for the period, the New History of the Five Dynasties, apparently was skeptical of this account of Shi Jingtang's ancestry, and instead merely gave Nieliji's name, further stating that it was unclear when or how he received the surname of Shi. Most likely, Shi Jingtang descended from the Shatuo sub-tribe Anqing (安慶), specifically, from the Shi clan (石) of ultimately Sogdian origin.

Shi Jingtang was born in 892, during the reign of Emperor Zhaozong of Tang, in Taiyuan. His mother was stated to be a Lady He, and it was not stated whether she was Shi Shaoyong's wife or concubine. (However, after he later became emperor, Shi Jingtang honored Shi Shaoyong's concubine Lady Liu, first as consort dowager, and then as empress dowager, suggesting the possibility that Lady He was Shi Shaoyong's wife and Shi Jingtang's "legal" mother, but that Lady Liu was his birth mother.) In his youth, Shi Jingtang was said to be quiet and stern. He studied the military strategies and particularly tried to take after Li Mu and Zhou Yafu.

When he grew up, he was known as one of the strongest warriors in the region due to his valor and martial prowess.^{[citation needed]}

The region that Li Keyong ruled subsequently became the state of Jin after Tang's fall in 907 (as Li Keyong carried the Tang-bestowed title of Prince of Jin), and after Li Keyong's death in 908, Li Cunxu succeeded him as the Prince of Jin, in rivalry with Tang's main successor state Later Liang. Li Cunxu subsequently made his adoptive brother (Li Keyong's adoptive son) Li Siyuan, a major general, the prefect of Dai Prefecture (代州 in modern Shuozhou, Shanxi). While Li Siyuan served as the prefect of Dai, he became impressed with Shi Jingtang and gave his Empress Li to Shi in marriage. Shi subsequently served under Li Siyuan in campaigns, becoming one of the two prominent officers under Li Siyuan (along with Li Siyuan's adoptive son Li Congke) due to his battlefield accomplishments.

Despite the familial relationship between Shi and Li Congke and their serving together under Li Siyuan, the two did not like each other and had a rivalry, although not overtly.
