== About (from [[https://en.wikipedia.org/wiki/Xianfeng_Emperor|Wikipedia]]) In 1853, the Taiping rebels captured Nanjing and for a while it seemed that Beijing would fall next; but the Taiping northern expedition was defeated and the situation stabilized. The Xianfeng Emperor dispatched several prominent mandarins, such as Zeng Guofan and the Mongol general Sengge Rinchen, to crush the rebellions, but they only obtained limited success. The biggest revolt of the Miao people against Chinese rule in history started in 1854, and ravaged the region until finally put down in 1873. In 1856, an attempt to regain Nanjing was defeated and the Panthay Rebellion broke out in Yunnan. == Context (from [[https://en.wikipedia.org/wiki/Xianfeng_Emperor|Wikipedia]]) Meanwhile, an initially minor incident on the coasts triggered the Second Opium War. Anglo-French forces, after inciting a few battles (not all victories for them) on the coast near Tianjin, attempted "negotiation" with the Qing government. The Xianfeng Emperor, under the influence of his Noble Consort Yi (later Empress Dowager Cixi), believed in Chinese superiority and would not agree to any colonial demands. He delegated Prince Gong for several negotiations but relations broke down completely when a British diplomat, Sir Harry Parkes, was arrested during negotiations on 18 September. The Anglo-French invasion clashed with Sengge Rinchen's Mongol cavalry on 18 September near Zhangjiawan before proceeding toward the outskirts of Beijing for a decisive battle in Tongzhou District, Beijing. On 21 September, at the Battle of Eight-Mile Bridge, Sengge Rinchen's 10,000 troops, including his elite Mongol cavalry, were completely annihilated after several doomed frontal charges against the concentrated firepower of the Anglo-French forces, which entered Beijing on 6 October. On 18 October 1860, the British and French forces went on to loot and burn the Old Summer Palace and Summer Palace. Upon learning about this news, the Xianfeng Emperor's health quickly deteriorated. During the Xianfeng Emperor's reign, China lost part of Manchuria to the Russian Empire. In 1858, according to the Treaty of Aigun, the territory between Stanovoy Mountains and Amur River was ceded to Russia, and in 1860, according to the Treaty of Beijing, the same thing happened also to the area east of Ussuri River. After that treaty, the Russians founded the city of Vladivostok in the area they had annexed. While negotiations with the European powers were being held, the Xianfeng Emperor and his imperial entourage fled to Jehol province in the name of conducting the annual imperial hunting expedition. As his health worsened, the emperor's ability to govern also deteriorated, and competing ideologies in court led to the formation of two distinct factions — one led by the senior official Sushun and the princes Zaiyuan and Duanhua, and the other led by Noble Consort Yi, who was supported by the general Ronglu and the Bannermen of the Yehenara clan.
