In short: Following the Chinese Civil War, the Kuomintang regime transformed Taiwan into a landscape of pervasive surveillance and political purging. From 1949 until 1992, the government systematically silenced dissent, targeting intellectuals, civilians, and perceived communists alike. This era of authoritarian control left a legacy of thousands of disappeared and executed citizens.

The White Terror began in 1949 after the Kuomintang (KMT) retreated to Taiwan, having lost the Chinese Civil War. Seeking to consolidate power, the regime imposed martial law, which lasted for 38 years and 57 days—the longest duration in the world at the time of its lifting in 1987. The repression was institutionalized through secret police units like the Taiwan Garrison Command, which utilized special criminal laws to bypass standard legal protections. By labeling critics as communist spies or separatists, the state justified the imprisonment and execution of thousands of people, including academics, doctors, and lawyers.

The violence was rooted in deep social tensions between the waishengren, who arrived with the KMT in the late 1940s, and the benshengren, who had lived under Japanese colonial rule for 50 years. The 228 Incident of 1947, sparked by a violent confrontation over contraband cigarettes, served as a precursor to the systematic purges. Following the uprising, Chiang Kai-shek’s government initiated a brutal crackdown that decimated the local elite. The atmosphere of fear was maintained through pervasive monitoring, sham trials in military courts, and the indoctrination of students through state-controlled school curriculums that promoted a singular Chinese identity.

The human cost of this era remains difficult to quantify, with estimated death tolls ranging from 10,000 to over 30,000. Many victims were held in remote, state-run facilities like the New Life Correction Center on Green Island. The repression extended to arbitrary arrests, such as the 1968 imprisonment of writer Bo Yang for his translation of a Popeye comic strip. It was not until the repeal of Article 100 of the Criminal Code in 1992 that the legal framework enabling these persecutions was finally dismantled, marking the official end of the White Terror period.
