The White Terror was the political repression of Taiwanese civilians and political dissenters under the Kuomintang (KMT)-ruled government. The period of White Terror is generally considered to have begun when martial law was declared in Taiwan on 19 May 1949, which was enabled by the 1948 Temporary Provisions against the Communist Rebellion, and ended on 21 September 1992 with the repeal of Article 100 of the Criminal Code, allowing for the prosecution of "anti-state" activities. The Temporary Provisions were repealed a year earlier on 22 April 1991 and martial law was lifted on 15 July 1987.

The Kuomintang (KMT), also referred to as the Guomindang (GMD), the Nationalist Party of China (NPC) or the Chinese Nationalist Party (CNP), is a major political party in the Republic of China, initially based on the Chinese mainland and then in Taiwan since 1949. The KMT is a centre-right to right-wing party and the largest in the Pan-Blue Coalition. Its primary rival is the Democratic Progressive Party (DPP) and its allies in the Pan-Green Coalition. As of 2024, the KMT is the largest single party in the Legislative Yuan. The current chairman is Eric Chu.
