Chiang Kai-shek (蔣介石; Pinyin: Jiǎng Jièshí; Cantonese: Jyäng Kī-shĕk;) (1887–1975) was the leader of the Republic of China, 1927-1975. He headed the Kuomintang Party (KMT) (or "Guomindang Party" (GMD) or Nationalist Party). His KMT controlled mainland China after he defeated regional warlords in the 1920s. The Japanese took over Manchuria in 1931, and invaded the rest of China in 1937, quickly controlling the major cities and seacoast.
Chiang was the Supreme Commander of the China-Burma-India (CBI)Theater for the Allies in 1941-45, but was ineffective in driving back the Japanese. After the defeat of Japan in 1945 the KMT battled the Chinese Communists under Mao Zedong, who won in 1948, forcing Chiang and his KMT to the offshore island of Taiwan, which Chiang ruled until his death. A modernizer who embraced Christianity and built a strong and lucrative alliance with the United States, Chiang could not overcome the corruption which had been tolerated by the KMT in China. After relocating to Taiwan, he overcame the corruption there and made the island a model of economic prosperity and capitalism.
