General Cao Kun (; courtesy name: Zhongshan () (December 12, 1862 – May 15, 1938) was a Chinese warlord and politician, who served as the President of the Republic of China from 1923 to 1924, as well as the military leader of the Zhili clique in the Beiyang Army; he also served as a trustee of the Catholic University of Peking. Early life and rise to leadership Cao was born to a poor family in Tianjin. During the First Sino-Japanese War in 1894, he went with the army to fight in Joseon. After the war was over he joined Yuan Shikai to participate in the training of the New Army (known as the Beiyang Army). Admired by Yuan, Cao managed to rise very quickly. By the time of the 1911 Xinhai Revolution he commanded the Beiyang 3rd Division. He was made a general in the Beiyang Army and led the Zhili clique after the death of Feng Guozhang.

That episode brought disrepute to the Beiyang government and the National Assembly, which lacked a quorum even to hold elections. It also turned all the rival factions against him, and his own clique began suffering from dissension. Relations with his chief protégé, Wu Peifu, soured and there were rumors of an impending split within the Zhili clique, but they stayed together to fight against the Fengtian clique. One of his first acts as president was to promulgate the 1923 Constitution of China. Hastily drafted by the guilt-ridden assembly, it was deemed the most democratic and progressive charter yet, but like previous charters, it was ignored completely. During a war against Zhang Zuolin in October 1924, Cao was betrayed and imprisoned by one of his own officers, General Feng Yuxiang, in the
