The Government of the Republic of China is the national authority whose actual-controlled territory consists of main island of Taiwan (Formosa), Penghu, Kinmen, Matsu, and other island groups, collectively known as Taiwan Area or Free Area. A unitary state, the ROC government, under the current constitutional amendments, is run by a de facto semi-presidential system, consists of the presidency and five branches (Yuan): the Executive Yuan, Legislative Yuan, Judicial Yuan, Examination Yuan, and Control Yuan. The president is the head of state, with the premier as the head of government, currently ruled by the Democratic Progressive Party (DPP) since 2016. Since the 2005 amendments of the Additional Articles of the Constitution, the Legislative Yuan has been the de facto unicameral parliamentary body of the country.
Originally established in 1912 in Nanjing, the Government of the Republic of China relocated several times before finally moving to Taipei, Taiwan, in 1949 because of its military losses in the Chinese Civil War. Up until the 1990s, the government has historically been dominated by the Kuomintang (KMT) under the one-party state Dang Guo authoritarian regime, before evolving into a multi-party democracy after martial law and the climate of White Terror gradually ended. This government was the internationally recognized official government of China until 1971 by the United Nations and until 1979 by the United States.
