Tang Jiyao
With the death of Sun Yat-sen in March 1925, a power struggle emerged within the Kuomintang, with the left-wing Wang Jingwei, the centrist Chiang Kai-shek and the right-wing Hu Hanmin all vying for control of the party apparatus. Suspected of having assassinated the KMT chairman Liao Zhongkai for supporting the continuation of the United Front, Hu Hanmin was arrested and exiled by Wang and Chiang, which resulted in the right-wing faction of the KMT losing power. Meanwhile, the Yunnan clique had revolted against the KMT's acting executive, claiming Tang Jiyao to be the rightful leader of the KMT. But Tang's forces were routed by the New Guangxi clique and he fled to San Francisco, where Tang joined together with Chen Jiongming to found the Public Interest Party, a political party that advocated for federalism and multi-party democracy.
