The first and only female emperor in Chinese history Wu Zetian

Wu Zetian, personal name Wu Zhao, was the first and only female emperor in Chinese history, and de facto ruler of the Tang dynasty from 665 to 705, ruling first through others and then (from 690) in her own right. From 665 to 690, she was first empress consort of the Tang dynasty (as wife of the Emperor Gaozong) and then, after his death, empress dowager (ruling through her sons Emperors Zhongzong and Ruizong). Unprecedented in Chinese history, she subsequently founded and ruled as female emperor of the Wu Zhou dynasty of China from 690 to 705. She was the only female sovereign in the history of China widely regarded as legitimate. Under her 40-year reign, China grew larger, becoming one of the great powers of the world, its culture and economy were revitalized, and corruption in the court was reduced. She was removed from power in a coup and died a few months later.

In early life, Wu was the concubine of Emperor Taizong. After his death, she married his ninth son and successor, Emperor Gaozong, officially becoming Gaozong's huanghou, or empress consort, the highest-ranking of the wives, in 655. Even before becoming empress consort, Wu had considerable political power. Once announced as the empress consort, she began to control the court, and after Gaozong's debilitating stroke in 660, she became administrator of the court, a position equal to the emperor's, until 705. As a young woman entering Gaozong's harem, Wu clashed with Empress Wang and Consort Xiao to gain the emperor's affection, and eventually expelled and killed them. After her wedding to Gaozong in 655, her rise to power was swift. A strong, charismatic, vengeful, ambitious and well-educated woman who enjoyed the absolute affection of her husband, Wu was the most powerful and influential woman at court during a period when the Tang dynasty was at the peak of its glory.
