In the 1930s, the region faced Japanese invasion. By 1949, the Chinese Communist Party's (CCP) People's Liberation Army had largely defeated the Kuomintang (KMT)'s National Revolutionary Army in the Chinese Civil War on the mainland. This forced the Kuomintang to relocate the Government and institutions of the Republic of China to the relative safety of Taiwan, an island which was placed under the control of the Republic of China after the surrender of Japan at the end of World War II in 1945. With the establishment of the People's Republic of China on October 1, 1949, the CPC-controlled government saw itself as the sole legitimate government of China, competing with the claims of the Republic of China, whose authority is now limited to Taiwan and other islands. This has resulted in a situation in which two co-existing governments compete for international legitimacy and recognition as the "government of China".
