The Tongmenghui (or T'ung-meng Hui, variously translated as Chinese United League, United League, Chinese Revolutionary Alliance, Chinese Alliance, United Allegiance Society, ) was a secret society and underground resistance movement founded by Sun Yat-sen, Song Jiaoren, and others in Tokyo, Japan, on 20 August 1905. It was formed from the merger of multiple Chinese revolutionary groups in the late Qing dynasty.
The Tongmenghui was created through the unification of Sun Yat-sen's Xingzhonghui (Revive China Society), the Guangfuhui (Restoration Society) and many other Chinese revolutionary groups. Among the Tongmenghui's members were Huang Xing, Li Zongren, Zhang Binglin, Chen Tianhua, Wang Jingwei, Hu Hanmin, Tao Chengzhang, Cai Yuanpei, Li Shizeng, Zhang Renjie, and Qiu Jin.
In 1906, a branch of the Tongmenghui was formed in Singapore, following Sun's visit there; this was called the Nanyang branch and served as headquarters of the organization for Southeast Asia. The members of the branch included Wong Hong-kui (; Huang Kangqu),Tan Chor Lam (; Chen Chu'nan; 1884-1971) and Teo Eng Hock (; Zhang Yongfu; originally a rubber shoe manufacturer). Tan Chor Lam, Teo Eng Hock and Chan Po-yin (; Chen Buxian; 1883-1965) started the revolution-related Chong Shing Chinese Daily Newspaper (?, meaning China revival), with the inaugural issue on 20 August 1907 and a daily distribution of 1,000 copies. The newspaper ended in 1910, presumably due to the Xinhai Revolution in 1911. Working with other Cantonese people, Tan, Teo and Chan opened the revolution-related Kai Ming Bookstore (, meaning open wisdom) in Singapore. For the revolution, Chan Po-yin raised over 30,000 yuan for the purchase and shipment (from Singapore to China) of military equipment and for the support of the expenses of people travelling from Singapore to China for revolutionary work.
In 1909, the headquarters of the Nanyang Tongmenghui was transferred to Penang. Sun Yat-Sen himself was based in Penang from July to December 1910. During this time, the 1910 Penang Conference was held to plan the Second Guangzhou Uprising. The Tongmenghui also started a newspaper, the Kwong Wah Jit Poh, with the first issue published in December 1910 from 120 Armenian Street, Penang.
After Shanghai was occupied by the revolutionaries in November 1911, the Tongmenghui moved its headquarters to Shanghai. After the Nanjing Provisional Government was established, the headquarters was moved to Nanjing. A general meeting was held in Nanking on 20 January 1912, with thousands of members attending. Hu Hanmin, who represented the Provisional President Sun Yat-sen, moved that the Tongmenghui oath be changed to "overthrow the Manchu government, consolidate the Republic of China, and implement the Min Sheng Chu I". Wang Jingwei was elected as Chairman, succeeding Sun. Wang resigned the following month, and Sun resumed the chairmanship.
After the establishment of the Republic of China, the Tongmenghui transformed itself into a political party on 3 March 1912, in preparation for participation in constitutional and parliamentary activities. It issued a Provisional Constitution of the Republic of China, which consisted of 34 articles, meaning it had 10 more than the constitutional proposal made when the Tongmenghui was a secret society. The leadership election was held on the same day, with Sun Yat-sen elected as Chairman, Huang Xing and Li Yuanhung as Vice-Chairmen. In May 1912, the Tongmenghui moved its headquarters to Beijing. At that time, the Tongmenghui was the largest party in China, with branches in Guangdong, Szechuan, Wuhan, Shanghai, Hangzhou, Suzhou, Anqing, Fuzhou and Tianjin. It had a membership of about 550 thousand. In August 1912, the Tongmenghui formed the nucleus of the Kuomintang, the governing political party of the republic.
In 1904, by combining republican, nationalist, and socialist objectives, the Tongmenghui came up with their political goal: to expel the Manchu people, to revive Zhonghua, to establish a Republic, and to distribute land equally among the people.
