On May 19, 1949, the Governor of Taiwan Province and the Ministry of National Defense, Republic of China (ROC), Chen Cheng, promulgated the "Order of Martial Law" to announce the imposition of Taiwan martial law . Until the order was lifted by the President Chiang Ching-kuo on July 15, 1987, Taiwan had been under martial law for more than 38 years, which was qualified as "the longest imposition of martial law by a regime anywhere in the world" at that time.
