About Wang Rong

Wang Rong, was a warlord in the final years of the Tang dynasty who later became the only ruler of the state of Zhao during the Five Dynasties and Ten Kingdoms period. Late in Tang, he initially tried to chart an independent course between the more powerful warlords Zhu Quanzhong and Li Keyong, but later was forced to become Zhu's vassal, although he continued to govern his domain without much interference from Zhu. After Zhu declared himself the emperor of a new dynasty of Later Liang, Wang continued to serve as a vassal and was created the Prince of Zhao. Later, though, when the Later Liang emperor tried to seize the Zhao domain by force, Wang broke away from Later Liang and realigned with Li Keyong's son and successor Li Cunxu the Prince of Jin instead. In 921, Wang was overthrown and killed in a coup led by his adoptive son Wang Deming, who subsequently took over his domain and changed back to the birth name of Zhang Wenli, before dying later in the year; Li Cunxu then defeated and killed Zhang's son and successor Zhang Chujin, incorporating Zhao into his Jin state.
