After the assassination of Sung Chiao-jen and Yuan Shihkai's attempts to remove the Nationalist Party of China from power, the leader of Guangdong Hu Hanmin joined the 1913 Second Revolution against him but was forced to flee to Japan with Sun Yat-sen after its failure. The city came under national spotlight again in 1917, when Prime Minister Duan Qirui's abrogation of the constitution triggered the Constitutional Protection Movement. Sun Yat-sen came to head the Guangzhou Military Government supported by the members of the dissolved parliament and the Southwestern warlords. The Guangzhou government fell apart as the warlords withdrew their support. Sun fled to Shanghai in November 1918 until the Guangdong warlord Chen Jiongming restored him in October 1920 during the Yuegui Wars. On 16 June 1922, Sun was ousted in a coup and fled on the warship "Yongfeng" after Chen sided with the Zhili Clique's Beijing government. In the following months Sun mounted a counterattack into Guangdong by rallying supporters from Yunnan and Guangxi, and in January established a government in the city for the third time.
