After the Japanese surrender at the end of World War II in 1945, the Korean Peninsula was divided into two zones along the 38th parallel, with the northern half of the peninsula occupied by the Soviet Union and the southern half by the United States. Negotiations on reunification failed. Soviet general Terentii Shtykov recommended the establishment of the Soviet Civil Authority in October 1945, and supported Kim Il-sung as chairman of the Provisional People's Committee for North Korea, established in February 1946. In September 1946, South Korean citizens rose up against the Allied Military Government. In April 1948, an uprising of the Jeju islanders was violently crushed. The South declared its statehood in May 1948 and two months later the ardent anti-communist Syngman Rhee became its ruler. The Democratic People's Republic of Korea was established in the North on 9 September 1948. Shtykov served as the first Soviet ambassador, while Kim Il-sung became premier.
