Cao Kun
His election as president was largely engineered by Duan Qirui and his Anhui clique. He was chosen because he was a civilian yet had close ties to the Beiyang Army and was neutral to both its Zhili and Anhui cliques. Lacking any military power of his own, he had to play Duan, Zhili leader Cao Kun, and Fengtian leader Zhang Zuolin against each other to stay in power.
