Emperor Daizong of Tang (727–779)
Born 727 CE, died 779 CE.
Emperor Daizong of Tang (11 November 726 – 10 June 779), personal name Li Yu (name changed in 758 after being created crown prince), né Li Chu (Chinese: 李俶), was an emperor of the Chinese Tang dynasty. Emperor Daizong was the eldest son of Emperor Suzong – the first emperor of the Tang dynasty to succeed as the eldest child. During the Anshi Rebellion (which Emperor Suzong's entire reign was dedicated to fighting), he served as a general of Tang and Huige joint operations that recaptured the capital Chang'an and the eastern capital Luoyang from the rebel state of Yan, and the Anshi Rebellion was finally put down early in his own reign, in 763. However, thereafter, the Tang state was plagued by warlords such as Tian Chengsi, Li Baochen, and Liang Chongyi who essentially governed their realms as independent states while only pledging nominal loyalty to the emperor. This would prove disastrous for future generations as subsequent Tang emperors were unable to remove or control these warlords and the central government's power was thus slowly eroded and diminished.
