Emperor Daizong of Tang, Li Yu

Timeline

1. 727–762Chang'an · Shaanxi ProvinceLi Yu was the eldest son of Emperor Suzong and was enfeoffed as Prince of Guangping. During the An Lushan Rebellion he campaigned with Guo Ziyi and others, earning merit in recovering the two capitals; he acceded at Lingwu in the first year of Baoying, changed the era name to Guangde, executed Shi Chaoyi, and the rebellion was thus pacified.
2. 763–779Chang'an · Shaanxi ProvinceIn the first year of Guangde the Tibetans captured Chang'an, which Daizong recovered through Guo Ziyi and others. During the Dali era the regional governors ran rampant, the three Hebei circuits carved out independent domains, eunuchs controlled the Shence Army, and court authority declined daily. Daizong was diligent and frugal, yet accumulated ills were hard to reverse.
