Zhili clique
The conflict came to be known as the Zhili–Anhui War and lasted from July 14 to July 18, 1920. Although Duan's army had been equipped and trained by Japan, it succumbed easily to Wu Peifu-led Zhili forces and their allies. His military power shattered, Duan fled to a Japanese settlement in Tianjin and became an apartment landlord. The Anhui clique began to lose its coherency, as some of its members became affiliated with either the Zhili clique or Zhang Zuolin's Fengtian faction. Only Zhejiang remained in the hands of the Anhui clique, although it eventually fell in 1924. Shandong was allowed by the Zhili clique to later be taken over by an Anhui warlord under strict conditions of neutrality. Nevertheless, some Anhui clique politicians remained active in government as the Zhili clique and Fengtian faction began to maneuver against each other. Jin Yunpeng, who had been a protege of Duan, was appointed premier in August 1920. Other Anhui members secretly mediated between Zhang Zuolin and Feng Yuxiang, an important leader in the Zhili clique, when the latter decided to revolt against his former allies in the Second Zhili–Fengtian War.
