The Kuomintang holds the "One China Principle" and maintains its claim that under the ROC Constitution (passed by the Kuomintang government in 1947 in Nanjing) the ROC has sovereignty over most of China, including, by their interpretation, both mainland China and Taiwan. After the Communist Party of China expelled the ROC in the Chinese Civil War from most of Chinese territory in 1949 and founded the PRC, the ROC's Chinese Nationalist government, which still held Taiwan, continued to claim legitimacy as the government of all of China. Under former President Lee Teng-hui, additional articles were appended to the ROC constitution in 1991 so that it applied effectively only to the Taiwan Area. The Kuomintang proclaims a modified form of the "One China" principle known as the "1992 Consensus". Under this "consensus", both governments "agree" that there is only one single sovereign state encompassing both mainland China and Taiwan, but disagree about which of the two governments is the legitimate government of this state. Former ROC President Ma Ying-jeou had re-asserted claims on mainland China as late as October 8, 2008.
