The Government of Republic of China proclaimed its constitutionalization on the day of 25 December 1947, which was followed by the elections of the Legislative Yuan & National Assembly, and that of the Presidency. Meanwhile, civil war enflamed between the Kuomintang (KMT) and the Chinese Communist Party (CCP). In May 1948, the government executed the ”Mobilization for the Suppression of Rebellion Provisional Act,” which thereby bestowed upon the president emergency powers. The deteriorating KMT government relocated to Taiwan in 1950, yet it needed a ”democratic” label to effect anti-Communist movements. Therefore, in the process of the KMT reformation, the government on the one hand attempted to re-establish authority, but also to adapt a democratic constitution on the other. Throughout 1947-1953, constitutionalization and pacification of anti-Communists inevitably faced some confrontations and contradictions in their execution. This paper attempts to draw on the diary of T'ao Hsi-Sheng to dissect and analyze these political issues.
