Li Chun

Li Chun launched a series of military campaigns to reassert central control over rebellious fanzhen. He defeated the warlords of Sichuan, Zhenhai, and other provinces, reducing their autonomy and restoring imperial authority.

Li Chun's forces defeated the powerful Zhaoyi fanzhen, whose military governor had rebelled. This victory was a major achievement of the Yuanhe Restoration, demonstrating the Tang court's renewed military strength.

After a long campaign, the Chengde fanzhen submitted to central authority. This was the last major fanzhen to be brought under control during Li Chun's reign, marking the peak of the Yuanhe Restoration.

Li Chun died in 820, possibly poisoned by eunuchs. His death ended the Yuanhe Restoration, and subsequent emperors were unable to maintain the central authority he had reestablished.
