civil service examination candidate who, influenced by Christian teachings, had a series of visions and believed himself to be the son of God, the younger brother of Jesus Christ, sent to reform China. A friend of Hong's, Feng Yunshan, utilized Hong's ideas to organize a new religious group, the God Worshippers’ Society (Bai Shangdi Hui), which he formed among the impoverished peasants of Guangxi province. Amid widespread social unrest and worsening famine, the rebellion not only posed the most serious threat towards Qing rulers, it has also been called the "bloodiest civil war of all time"; during its fourteen-year course from 1850 to 1864 between 20 and 30 million people died. Hong Xiuquan, a failed civil service candidate, in 1851 launched an uprising in Guizhou province, and established the Taiping Heavenly Kingdom with Hong himself as king. Hong announced that he had visions of God and that he was the brother of Jesus Christ. Slavery, concubinage, arranged marriage, opium smoking, footbinding, judicial torture, and the worship of idols were all banned. However, success led to internal feuds, defections and corruption. In addition, British and French troops, equipped with modern weapons, had come to the assistance of the Qing imperial army. It was not until 1864 that Qing armies under Zeng Guofan succeeded in crushing the revolt. After the outbreak of this rebellion, there were also revolts by the Muslims and Miao people of China against the Qing dynasty, most notably in the Miao Rebellion (1854–1873) in Guizhou, the Panthay Rebellion (1856–1873) in Yunnan and the Dungan Revolt (1862–77) in the northwest. The Western powers, largely unsatisfied with the Treaty of Nanjing, gave grudging support to the Qing government during the Taiping and Nian Rebellions. China's income fell sharply during the wars as vast areas of farmland were destroyed, millions of lives were lost, and countless armies were raised and equipped to fight the rebels. In 1854, Britain tried to re-negotiate the Treaty of Nanjing, inserting clauses allowing British commercial access to Chinese rivers and the creation of a permanent British embassy at Beijing. In 1856, Qing authorities, in searching for a pirate, boarded a ship, the Arrow, which the British claimed had been flying the British flag, an incident which led to the Second Opium War. In 1858, facing no other options, the Xianfeng Emperor agreed to the Treaty of Tientsin, which contained clauses deeply insulting to the Chinese, such
