Hu Hanmin
Yuan Shikai proclaimed himself emperor in December 1915. While exiled in Japan in 1914, Sun established the Chinese Revolutionary Party on 8 July 1914, but many of his old revolutionary comrades, including Huang Xing, Wang Jingwei, Hu Hanmin and Chen Jiongming, refused to join him or support his efforts in inciting armed uprising against Yuan. To join the Revolutionary Party, members had to take an oath of personal loyalty to Sun, which many old revolutionaries regarded as undemocratic and contrary to the spirit of the revolution. As a result, he became largely sidelined within the Republican movement during this period.
