Concubine to sole female emperor of China
Wu Zetian, a timber merchant's daughter, entered Emperor Taizong's palace as a low-ranking concubine at thirteen, survived his death by being sent to a Buddhist nunnery, and was brought back as consort to his son Gaozong. She displaced Empress Wang, then governed alongside and after the ailing Gaozong. She ruled through her sons, and in 690 declared herself emperor of a new Zhou dynasty, the only woman in Chinese history to take the throne in her own name.
