Empress Dowager Cixi, 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. After the Xianfeng Emperor's death in 1861, his five-year-old son became the Tongzhi Emperor, and Cixi assumed the role of co-empress dowager alongside Xianfeng'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. Cixi then consolidated control over the dynasty when she installed her nephew as the Guangxu Emperor at the death of the Tongzhi Emperor in 1875. Ci'an continued as co-regent until her death in 1881.

The Qing dynasty, officially the Great Qing, was a Manchu-led imperial dynasty of China and the last imperial dynasty in Chinese history. The dynasty, proclaimed in Shenyang in 1636, seized control of Beijing in 1644, which is considered the start of the dynasty's rule. The dynasty lasted until 1912, when it was overthrown in the Xinhai Revolution. In Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multi-ethnic Qing dynasty assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 the fourth-largest empire in world history in terms of territorial size. With over 426 million citizens in 1907, it was the most populous country in the world at the time.
