Emperor Gaozong of Tang
Emperor Gaozong of Tang (21 July 628 – 27 December 683), personal name Li Zhi, was the third emperor of the Tang dynasty in China, ruling from 649 to 683 (although after January 665 power and governance was primarily in the hands of his powerful second wife Empress Wu, later known as Wu Zetian).
Emperor Gaozong was the son of Emperor Taizong and Empress Zhangsun.
Emperor Gaozong was aided in his rule by Empress Wu during the later years of his reign after a series of strokes left him incapacitated.
Emperor Gaozong delegated all matters of state to his Strong wife and after he died in 683, power fell completely into the hands of Empress Wu, who subsequently became the only Empress regnant in Chinese history.
After his death, he was interred at the Qianling Mausoleum along with Wu Zetian.
Historians have generally viewed Emperor Gaozong as a weak ruler, inattentive to the business of the state and leaving such business to his powerful wife Empress Wu.
During the first part of his reign, Tang territorial gains, which started with his father Emperor Taizong, continued, including the conquest of Baekje, Goguryeo, and the Western Turkic Khaganate, but throughout the 670s, much of those gains were lost to the Tibetan Empire, Silla, Khitan, and Balhae.
Further, territory previously conquered that belonged to both the Göktürks and the Western Turkic Khaganate were subjected to repeated rebellions.
