Korean Liberation Day 09
Liberation Day (Korean hangul: 광복절, hanja: 光復節, RR: Gwangbokjeol, MR: Kwangbokchŏl, lit "restoration of light") is a public holiday in South Korea, celebrated annually on August 15. It coincides with Victory over Japan Day, which liberated Korea from Japanese occupation. In North Korea, it is celebrated as Fatherland Liberation Day (Chosŏn'gŭl: 조국해방의 날, hanja: 祖國解放의날, MR: Chogukhaebang'ŭi nal, RR: Jogukhaebangui nal).
Korea did not gain actual independence on August 15, 1945, but was occupied by the Soviet and United States armies, which oversaw the decommissioning of Japanese troops in Korea. The northern half of the peninsula was occupied by the Red Army, and the southern half was occupied by the United States.
