The Xianfeng Emperor (17 July 1831 – 22 August 1861), also known by his temple name Emperor Wenzong of Qing, personal name Yizhu, was the eighth emperor of the Qing dynasty, and the seventh Qing emperor to rule over China proper. During his reign, the Qing dynasty experienced several wars and rebellions including the Taiping Rebellion, the Nian Rebellion, and the Second Opium War. He was the last Chinese emperor to exercise sole power.
The fourth son of the Daoguang Emperor, he assumed the throne in 1850 and inherited an empire in crisis. A few months after his ascension, the Taiping Rebellion broke out in southern China and rapidly spread, culminating in the fall of Nanjing in 1853. Contemporaneously, the Nian Rebellion began in the north, followed by ethnic uprisings (the Miao Rebellion and the Panthay Rebellion) in the south. The revolts ravaged large parts of the country, caused millions of deaths and would not be quelled until well into the reign of the Xianfeng Emperor's successor. Qing defeat during the first phase of the Second Opium War led to the Treaty of Tientsin and the Treaty of Aigun, the latter of which resulted in the cession of much of Manchuria to the Russian Empire. Negotiations broke down and hostilities resumed soon after, and in 1860 Anglo-French forces entered Beijing and burned the Old Summer Palace. The Xianfeng Emperor was forced to flee for the imperial estate at Jehol, and the Convention of Peking was negotiated in his absence.
