Empress Dowager Cixi, of the Manchu Yehe Nara clan, was a Chinese noblewoman, concubine and later regent who effectively controlled the Chinese government in the late Qing dynasty for 47 years, from 1861 until her death in 1908. Selected as a concubine of the Xianfeng Emperor in her adolescence, she gave birth to a son, Zaichun, in 1856. After the Xianfeng Emperor's death in 1861, the young boy became the Tongzhi Emperor, and she assumed the role of co-empress dowager, alongside the Emperor's widow, Empress Dowager Ci'an. Cixi ousted a group of regents appointed by the late emperor and assumed the regency along with Ci'an, who later mysteriously died. Cixi then consolidated control over the dynasty when she installed her nephew as the Guangxu Emperor at the death of her son, the Tongzhi Emperor, in 1875. This was contrary to the traditional rules of succession of the Qing dynasty that had ruled China since 1644.
