The constitution was drafted in by the KMT while the ROC still governed the Chinese mainland, went into effect on 25 December 1947. The ROC remained under martial law from 1948 until 1987 and much of the constitution was not in effect. Political reforms beginning in the late 1970s resulted in the end of martial law in 1987, and Taiwan transformed into a multiparty democracy in the early 1990s. The constitutional basis for this transition to democracy was gradually laid in the Additional Articles of the Constitution of the Republic of China. In addition, these articles localized the Constitution by suspending portions of the Constitution designed for governance of China and replacing them with articles adapted for the governance of and guaranteeing the political rights of residents of the Taiwan Area, as defined in the Act Governing Relations between the People of the Taiwan Area and the Mainland Area.
