Wu Zetian
Wu Zetian (February 17, 624 – December 16, 705), also known as Wu Zhao, Wu Hou, and during the later Tang dynasty as Tian Hou, referred to in English as Empress Consort Wu or by the deprecated term "Empress Wu", was a Chinese sovereign who ruled unofficially as Empress and later, officially as Emperor of China (皇帝) during the brief Zhou dynasty (周, 684-705), which interrupted the Tang dynasty (618–690 & 705–907). Wu was the only female emperor of China in more than four millennia.
Wu was the concubine of Emperor Taizong. After his death, she married his successor - his ninth son, Emperor Gaozong, officially becoming Gaozong's huanghou (皇后, variously translated as "empress", "wife", or "empress consort") in 655, although having considerable political power prior to this. After Gaozong's debilitating stroke in 690, Wu Zetian became administrator of the court, a position equal as emperor, until 705.
The importance to history of Wu Zetian's period of political and military leadership includes the major expansion of the Chinese empire, extending it far beyond its previous territorial limits, deep into Central Asia, and engaging in a series of wars on the Korean peninsula, first allying with Silla against Goguryeo, and then against Silla over occupation of formerly Goguryeo territory. Within China, besides the more direct consequences of her struggle to gain and maintain supreme power, Wu's leadership resulted in important effects regarding social class in Chinese society and in relation to state support for Taoism, Buddhism, education, and literature. Wu Zetian also had a monumental impact upon the statuary of the Longmen Grottoes and the "Wordless Stele" at the Qianling Mausoleum, as well as the construction of some major buildings and bronze castings that no longer survive.
