or Chiang Chieh-shih or Jiang Jieshi born Oct. 31, 1887, Zhejiang, China died April 5, 1975, Taipei, Taiwan Head of the Nationalist government in China (1928-49) and later in Taiwan (1949-75). After receiving military training in Tokyo, in 1918 he joined Sun Yat-sen, leader of the Nationalist Party, which was trying to consolidate control over a nation in chaos. In the 1920s Chiang became commander in chief of the revolutionary army, which he sent to crush warlords active in the north (see Northern Expedition). In the 1930s he and Wang Jingwei vied for control of a new central government with its capital at Nanjing. Faced with Japanese aggression in Manchuria and communist opposition led by Mao Zedong in the hinterland, Chiang decided to crush the communists first. This proved to be a mistake, and Chiang was forced into a temporary alliance with the communists when war broke out with Japan in 1937. After the war China's civil war resumed, culminating in the Nationalists' flight to Taiwan in 1949, where Chiang ruled, supported by U.S. economic and military aid, until his death, when his son, Chiang Ching-kuo, took up the reins of government. His years ruling Taiwan, though dictatorial, oversaw the island's economic development and increasing prosperity even in the face of its precarious geopolitical position. His failure to keep control of mainland China has been attributed to poor morale among his troops, lack of responsiveness to popular sentiment, and lack of a coherent plan for making the deep social and economic changes China required
