Mao Zedong’s communists take power in Beijing in October 1949 after defeating Chiang Kai-shek’s Kuomintang (KMT) nationalists in a civil war. The KMT flee to the island of Taiwan and form their own government in Taipei in December, cutting off contacts with mainland China. In 1950 Taiwan becomes an ally of the United States, which is at war with Communist China in Korea.
