Emperor Ai of Tang
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
Emperor Dezong of Tang
Emperor Dezong of Tang (27 May 742 – 25 February 805), personal name Li Kuo, was an emperor of the Chinese Tang Dynasty and the oldest son of Emperor Daizong. His reign of 26 years was the third longest in the Tang dynasty (surpassed only by Emperor Xuanzong and Emperor Gaozong). Emperor Dezong started out as a diligent and frugal emperor and he tried to reform the governmental finances by introducing new tax laws. His attempts to destroy the powerful regional warlords and the subsequent mismanagement of those campaigns, however, resulted in a number of rebellions that nearly destroyed him and the Tang Dynasty. After those events, he dealt cautiously with the regional governors, causing warlordism to become unchecked, and his trust of eunuchs caused the eunuchs' power to rise greatly. He was also known for his paranoia about officials' wielding power, and late in his reign, he did not grant much authority to his chancellors.
