Zhao Kuangming (趙匡明), courtesy name Zanyao (讚堯), was a warlord late in the Chinese Tang dynasty who controlled Jingnan Circuit (荊南, headquartered in modern Jingzhou, Hubei) from 903 to 905 as its military governor (jiedushi) and formed a power bloc with his brother Zhao Kuangning the military governor of Zhongyi Circuit (忠義, headquartered in modern Xiangyang, Hubei), until both he and his brother were defeated by the major warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan).
At Zhu's recommendation, Zhao Deyin was allowed to remain as military governor of the circuit, which was then renamed Zhongyi.
[5] Emperor Zhaozong (who was by this point under Zhu's physical control) initially commissioned Zhao Kuangming only as the commander of the Jingnan army (行軍司馬, Xingjun Sima) but gave him the honorary title of acting Situ (司徒, one of the Three Excellencies) as well.
Wang Jian treated him as an honored guest and commissioned him as the military governor of Wuxin Circuit (武信, headquartered in modern Suining, Sichuan).
[1] Later, after Wang Jian founded Former Shu as its emperor, he made Zhao Kuangming the chief judge of the supreme court (大理卿, Dali Qing) and the minister of public works (工部尚書, Gongbu Shangshu).
