Zhang Zuolin
By the early 1920s, Heilongjiang, Jilin, Fengtian, Jehol, Chahar and Suiyuan provinces were under the control of the so-called Fengtian Clique, led by Zhang Zuolin (Chang Tso-lin). The First Zhili-Fengtian War ended in May 1922 with the defeat of the Fengtian Clique and the expulsion of Zhang Zuolin from the Zhili-Fengtian coalition government in Beijing.
