Elections in Taiwan are held on national and local level. On the national level, the head of state, the President, and members of the national legislature, the Legislative Yuan, are elected directly by citizens of Taiwan. National elections are held every four years.
Local self-government bodies including special municipalities, counties, cities, townships, county-controlled cities, indigenous districts and villages have their own elections. The heads as well as legislators of the self-government bodies are all directly elected by citizens who have registered their residency in the respective territory. Local elections are held every four years at intervals between national elections.
Elections are supervised by the Central Election Commission (CEC), an independent agency under the central government, with the municipality, county and city election commissions under its jurisdiction. The minimum voting age is twenty years. Voters must satisfy a four-month residency requirement before being allowed to cast a ballot.
Elections were held for the first time in Taiwan by the Japanese colonial government on 22 November 1935, electing half of the city and township councillors.The other half were appointed by the prefectural governors. Only men aged 25 and above and who had paid a tax of five yen or more a year were allowed to vote, which was only 28,000 out of the 4 million population. The elections were held again in 1939, but the 1943 election was cancelled due to the second world war.
The government of the Republic of China, led by Kuomintang, retreated to Taiwan in 1949 after losing the Chinese Civil War with the Communist Party of China. At that time, the Temporary Provisions Effective During the Period of Communist Rebellion was enforced and largely restricted civil and political rights including voting right of the Taiwanese people. In addition, the Martial law in Taiwan also prohibited most forms of oppositions. From 1949 to 1990, the President was selected by the National Assembly first elected in 1947 and which had never been reelected since. The Legislative Yuan also had not been reelected since 1948. The provincial Governor and municipal Mayors were appointed by the central government. Direct elections were only held for local governments at the county level, and for legislators at the provincial level.
