Yan Xishan

Yan Xishan (Chinese: 閻錫山; pinyin: Yán Xīshān; Wade–Giles: Yen² Hsi¹-shan¹; 8 October 1883 – 23 May 1960; also romanized as Yen Hsi-shan) was a Chinese warlord who served in the government of the Republic of China from June 1949 to March 1950 as its last premier in mainland China and first premier in Taiwan. He effectively controlled the province of Shanxi from the 1911 Xinhai Revolution to the 1949 Communist victory in the Chinese Civil War. He maintained an ambivalent attitude towards the Communists until 1939, and participated in the Second United Front against the Japanese from 1937. He subsequently negotiated with the Japanese from 1940 to 1943, and allied himself with the Japanese against the Communists from 1944 until fleeing Shanxi in 1949. The resistance of his well-armed forces in Taiyuan posed a major obstacle to Communist victory in the Civil War.

As the leader of a relatively small, poor, remote province, he survived Yuan Shikai, the Warlord Era, the Nationalist Era, the Japanese invasion of China and the subsequent civil war, being forced from office only when the Nationalist armies with which he was aligned had completely lost control of the Chinese mainland, isolating Shanxi from any source of economic or military supply.
