Duan Qirui (Chinese: 段祺瑞; pinyin: Duàn Qíruì; Wade–Giles: Tuan Ch'i-jui, pronounced [twân tɕʰǐ.ɻwêɪ]) (March 6, 1865 – November 2, 1936) was a Chinese statesman and general who controlled the Beijing Government during the late 1910s. He was the Premier of China on four occasions between 1913 and 1918, and from 1924 to 1926 he served as acting Chief Executive of China in Beijing. As the last leader of the Beiyang Army, Duan was highly respected among the warlords and people of China, and was the founder of the Anhui Clique.
A graduate of the Tianjin Military Academy, Duan studied military science in Germany and became a prominent artillery commander under Yuan Shikai. Following the Xinhai Revolution in 1911 and the fall of the Qing dynasty, he became minister of war and premier in the Yuan cabinet. He opposed Yuan's restoration of monarchy in China and, upon Yuan's death, continued as premier and took effective control of northern China. His tenure was marked by political infighting as well as conflict with southern parliamentarians under the leadership of Sun Yat-sen.
