Emperor Ai of Tang
Emperor Ai of Tang (27 October 89226 March 908), also known as Emperor Zhaoxuan (), born Li Zuo, later known as Li Chu (), was the last emperor of the Tang dynasty of China. He reigned—as but a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong.
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.
