Li Maozhen (; 856 – May 17, 924), born Song Wentong (), courtesy name Zhengchen (), formally Prince Zhongjing of Qin (), 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 (鳳翔, in modern Baoji, Shaanxi), 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 (who would later found Former Shu) and Zhu Quanzhong (who would later found Later Liang). 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 (although he would receive both of those titles later in his life), this was typically viewed as the end of Qi as an independent state. Background Song Wentong was born in 856, during the reign of Emperor Xuānzong of Tang. He was described as "from Boye" (博野, in modern Baoding, Hebei) — but was clearly not born there, as his family had, for generations, belonged to the Boye Army, which originally belonged to Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) that had its origins from Boye, but which had been stationed near the Tang imperial capital Chang'an ever since its commander Li Huan () refused to submit to Wang Tingcou, who had seized Chengde Circuit and rebelled against the imperial government, as Li Huan eventually fought his way out of attacks by Wang and took his army to the Chang'an region. Song Wentong's grandfather was named Song Duo (); his grandmother was a Lady Zhang; his father was named Song Duan (); his mother was a
