Li Maozhen, Chinese warlord and king (born 856)

Li Maozhen, born Song Wentong (宋文通), courtesy name Zhengchen (正臣), formally Prince Zhongjing of Qin (秦忠敬王), was the only ruler of the Chinese Five Dynasties and Ten Kingdoms period state Qi (901–924). He had become a powerful warlord during the reign of Emperor Zhaozong of Tang, the penultimate emperor of the preceding Tang dynasty, with his power centered on his capital Fengxiang, and at times had effective control of Emperor Zhaozong. However, his power gradually waned due to defeats at the hands of fellow warlords Wang Jian and Zhu Quanzhong. After Zhu usurped the Tang throne and established Later Liang, Li Maozhen refused to submit and continued to use the Tang-bestowed title of Prince of Qi as well as maintain the Tang era name, but his territory became even more reduced due to wars with Former Shu and Later Liang. After Later Liang was conquered by Later Tang, whose Emperor Zhuangzong claimed to be a legitimate successor of Tang, Li Maozhen submitted as a subject and was created the Prince of Qin in 924. He died soon thereafter, and was succeeded as by his son Li Jiyan as the military governor (Jiedushi) of Fengxiang, but as Li Jiyan was not made the Prince of Qi or Qin at that point, this was typically viewed as the end of Qi as an independent state.
