Korean Provisional Government, government in exile organized in April 1919 in Shanghai by Korean patriots. The provisional government was formed in reaction to Japanese suppression of the March 1st Movement, the struggle for Korean independence from Japanese rule that had begun with a proclamation of independence issued by 33 prominent Koreans on March 1, 1919, and a number of massive demonstrations that occurred in Korea wherever the proclamation was read. Leading members of the Korean Provisional Government included such national leaders as Syngman Rhee, An Ch’ang-ho, and Kim Ku.
With the establishment of the provisional government, Korea was able to make more concerted efforts toward achieving independence from Japan, and it made immediate contacts with various independence groups both at home and abroad. By 1922 all of the Korean resistance groups in Manchuria were unified under the provisional government’s leadership. To help gain their aims, the leaders published a newspaper, The Independent, which greatly enhanced popular consciousness of political participation. They also sent delegations to the United States and Europe to draw attention to their cause.
Nevertheless, the Korean Provisional Government soon encountered insurmountable problems. Internally, the Japanese suppressed all nationalistic dissension in Korea; they even prohibited use of the Korean language in the later 1930s. Externally, the coalition that had formed the provisional government began to grow apart. Although Syngman Rhee was elected the nominal president, he remained in the United States, attempting to solicit Western moral support. The premier, Yi Tong-hwi, began to seek Soviet military aid for revolutionary operations in Manchuria. Kim Ku drew close to the right-wing Chinese Nationalists of Chiang Kai-shek.
With the liberation of Korea from Japanese occupation at the end of World War II, the Korean Provisional Government came to an end. Its members returned to Korea, where they put together their own political organizations in what came to be South Korea and competed for power.
