Sung Chiao-jen (sŏŏng jyou-jŭn), 1882–1913, Chinese revolutionary and political leader. He was a founding member (1905) and a leading activist in the Revolutionary Alliance (see Sun Yat-sen), an organization dedicated to overthrowing the Manchu dynasty in favor of a republic. After the republican revolution of 1911, Sung guided the Revolutionary Alliance into a merger with several parliamentary parties to form the Kuomintang, or Nationalist party. The parliamentary majority achieved by the Kuomintang in the elections of 1912–13 was largely due to Sung's superb organizing ability. He advocated a party cabinet to check the power of the first president, Yüan Shih-kai. Sung was assassinated, allegedly at the instigation of Yuan.
