Empress Dowager Cixi (Mandarin pronunciation: [tsʰɹ̩̌.ɕì]; 29 November 1835 – 15 November 1908) was a Manchu noblewoman of the Yehe Nara clan who effectively controlled the Chinese government in the late Qing dynasty as empress dowager and regent for almost 50 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.
