Emperor Muzong of Tang (795–824)
Born 795 CE, died 824 CE.
Emperor Muzong of Tang (July 26, 795 – February 25, 824), personal name Li Heng, né Li You (李宥) (name changed 812), was an emperor of the Tang dynasty of China. He reigned from 820 to 824. Emperor Muzong was the son of Emperor Xianzong. He was created crown prince in 812 during the reign of Emperor Xianzong and, after Emperor Xianzong was allegedly assassinated by a eunuch, Li Heng was proclaimed emperor in 820. After succeeding to the throne, Muzong spent his time feasting and heavily drinking, thereby neglecting his duties as emperor. Meanwhile, the temporarily subdued regional military governors (jiedushi) began to challenge the central Tang government, leading to the new de facto independence of three circuits north of the Yellow River, which Emperor Xianzong had subdued. Internally, corruption was rife. Emperor Muzong's brief reign came to an end in 824, and was viewed as the start of the downward spiral of the Tang dynasty.
