The Tongmenghui (同盟會 Pinyin: Tóng Méng Huě, literal meaning: "United Allegiance Society"), also known as the United League or the Revolutionary Alliance, was organized by Sun Yat-sen and Sung Chiao-jen in Tokyo, Japan on August 20, 1905.
The new body was created through the unification of Sun's Xingzhonghui (Revive China Society), the Guangfuhui (Restoration Society) and other Chinese revolutionary groups.
Combining republican, nationalist, and social objectives, the Tongmenghui's political platform was "to overthrow the Manchu barbarians, to restore China to the Chinese, to establish a republic, and to distribute land equally."
After the establishment of the Republic of China, the Tongmenghui formed, in August 1912, the nucleus of Sun's new Kuomintang (Nationalist Party).
The epic historical novel Romance of the Three Kingdoms portrays Pang Tong as a genius military tactician, and describes Pang and strategist Zhuge Liang in equal terms.
Pang Tong was born in Xiangyang in East Wu, and so initially served the lord Sun Quan.
Pang Tong then went to serve Liu Bei, and mapped out the occupation of Liu Zhang's territory in Yizhou (modern Sichuan), which Zhuge Liang had decided years ago to be the heartland of Liu Bei's kingdom.
