Taiwan is a multi-party democracy. The 2000 presidential victory of Democratic Progressive Party (DPP) candidate Chen Shui-bian followed more than 50 years of rule by the Kuomintang (KMT) and marked the first transition from one political party to another in the Taiwanese history, reported by a Government Information Office (GIO) website as the "first ever in Chinese history". This followed gradual democratic reforms since the 1980s and 1990s; most notably, martial law was lifted in 1987, and the Temporary Provisions Effective During the Period of Communist Rebellion were repealed in 1991 for Republic of China Constitution to be effective in Taiwan. The human rights record in Taiwan is generally held to have experienced significant transformation since the 1990s.
