Cao Kun
Within the Zhili clique Feng was demoted by Wu Peifu and sent to guard the southern suburbs of Beijing. In 1923 Feng was inspired by Sun Yat-sen and secretly plotted with Hu Jingyi and Xue Yue to overthrow Wu Peifu and Cao Kun, who controlled the Beiyang government. When the Second Zhili–Fengtian War began in 1924, Feng was in charge of defending Rehe against the Fengtian clique. However, he switched sides and seized the capital in the Beijing Coup on 23 October 1924. This turnabout prompted Shandong warlord Zhang Zongchang to join the Fengtian and led to a decisive defeat of the Zhili forces. Hence, Feng's coup brought far-reaching political changes in China. Feng imprisoned Zhili-leader and president Cao Kun, installed the more liberal Huang Fu, evicted the last Emperor Puyi from the Forbidden City and invited Sun Yat-sen to Beijing to resurrect the Republican government and reunify the country. Despite being severely ill already, Sun came to Beijing and died there in April 1925.
