Wu Zetian (17 February 624 – 16 December 705), personal name Wu Zhao, was Empress of China from 660 to 705, ruling first through others and later in her own right. She ruled as empress consort through her husband Emperor Gaozong and later as empress dowager through her sons Emperors Zhongzong and Ruizong, from 660 to 690. She subsequently founded and ruled as Empress Regnant 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 45-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 eventually removed from power during a coup and died a few months later.
