蔣經國
After the death of Chiang Kai-shek in 1975, Vice President Yen Chia-kan briefly took over from 1975 to 1978, according to the Constitution, but the actual power was in the hands of Premier Chiang Ching-kuo (), who was KMT chairman and a son of Chang Kai-shek. During the presidency of Chiang Ching-kuo from 1978 to 1988, Taiwan's political system began to undergo gradual liberalization.
