Song Jiaoren
In March 1913, the KMT leader Song Jiaoren was assassinated by order of the Beiyang government. In retaliation, Sun Yat-sen called for a Second Revolution to overthrow Yuan Shikai, organizing revolutionary forces of the southern provinces against the Beiyang government in an armed conflict, but the revolt was unsuccessful. Yuan subsequently dissolved parliament, abolished the constitution and reorganized provincial governments, effectively transforming the Republic of China into a dictatorship. The failure of the revolution forced Sun to flee to Japan, where he continued to receive support from Zhang Renjie, who was now making money on the Shanghai Stock Exchange.
