Wu Zetian

Empress Wu (624 – 16 December 705), commonly known as Wu Zetian, personal name Wu Zhao, was the only female sovereign in the history of China. She had previously held power as the empress consort of Emperor Gaozong of the Tang dynasty from 660 to 683 and as empress dowager during the reigns of her sons, Emperors Zhongzong and Ruizong, between 683 and 690. She was the sole ruler of the self-styled Zhou dynasty from 690 to 705.

In her early life, Wu served as a concubine of Emperor Taizong. After his death, she married his successor, Emperor Gaozong, becoming empress in 655. Wu exercised substantial political influence even before her elevation and gradually came to dominate court affairs. After Gaozong suffered a debilitating stroke in 660, she effectively administered the empire on his behalf until his death in 683. Breaking with precedent, Wu then consolidated power and prevented her sons from ruling. In 690, she proclaimed the Zhou dynasty in place of the Tang and crowned herself emperor.

During her 45-year de facto rule over China, Wu institutionalized the use of informants and enforced stringent legal measures, purged members of the Tang royal house and veteran officials from earlier administrations, reformed the civil service system to promote merit, patronized Buddhism as well as literature and the arts, and conducted military campaigns against Turkic and Tibetan incursions. Her rule formed part of the High Tang period, a historic peak in China’s political power and cultural influence. In her later years, her governance became increasingly autocratic and extravagant. She was removed from power in the Shenlong Coup, which abolished the Zhou dynasty and restored the Tang, and died a few months later.
