See it on the Korean History map →What happened
Emperor Hirohito's radio broadcast on August 15, 1945, announced Japan's acceptance of Allied terms, after the atomic bombings and the Soviet declaration of war on August 8. Crowds filled Korean streets. Lyuh Woon-hyung's Committee for the Preparation of Korean Independence set up local committees and in September declared a People's Republic. Soviet troops were already in the north; US forces landed at Incheon on September 8. Gwangbokjeol (광복절) is a national holiday in South Korea; North Korea marks it as Liberation Day.
Why it matters
Liberation came through Allied victory rather than Korean arms, so foreign powers, not Koreans, decided what came next, starting with the division.
How we know
The surrender broadcast, Allied and Japanese records, newspapers and photographs of August 1945, and memoirs of Lyuh Woon-hyung's circle and returning exiles.
Still debated
Whether Korean leaders could have formed a unified government on their own, had the occupying powers not intervened, is one of modern Korea's big counterfactual debates.
Connections (4)
▸Japanese colonial rule of Korea ended with Liberation of Korea (Gwangbokjeol)Well documented
The connection
Colonial rule ended not through a Korean uprising but through Japan's defeat in the Pacific War. When Japan announced its surrender on August 15, 1945, the Government-General asked Lyuh Woon-hyung to keep order, then formally surrendered to US forces in Seoul on September 9.
When and how
Seoul, August 15 – September 9, 1945; Governor-General Abe Nobuyuki surrendered to General John R. Hodge.
How we know
The surrender documents, Government-General records of the August handover talks, and newspapers and photographs of the period.
Debates and open questions
Whether the Korean Liberation Army's planned operations, cut short by the sudden surrender, would have given Koreans a stronger voice afterward is a common counterfactual.
▸Liberation of Korea (Gwangbokjeol) came together with Division of Korea at the 38th parallelWell documented
The connection
The line was drawn before liberation day. Soviet troops entered northern Korea from August 9, and on the night of August 10–11 US planners proposed the 38th parallel as the boundary for accepting Japan's surrender. So the same surrender that freed Korea also handed it to two occupying armies.
When and how
Washington, August 10–11, 1945; written into General Order No. 1, issued September 2, 1945; US forces arrived September 8.
How we know
Rusk's and Bonesteel's later accounts, State-War-Navy Coordinating Committee records, and the text of General Order No. 1.
Debates and open questions
Whether the US could have drawn the line elsewhere or avoided one, and why Stalin halted at the parallel, remain debated.
▸Name-change policy (soshi-kaimei) was reversed after Liberation of Korea (Gwangbokjeol)Well documented
The connection
Once Japan surrendered, Korean families dropped their imposed Japanese names. The US military government's Korean Name Restoration Order of October 1946 formally voided the colonial registrations, restoring Korean names in household records across the south.
When and how
Southern Korea, October 23, 1946, under the US military government; the north also abandoned the names after 1945.
How we know
The text of the Name Restoration Order and household registers that record the restored surnames.
Debates and open questions
How many people quietly kept Japanese names, for example Koreans who stayed in Japan and used them in daily life, is uncertain and hard to measure.
▸Provisional Government of the Republic of Korea returned home only after Liberation of Korea (Gwangbokjeol)Well documented
The connection
Japan's sudden surrender came before the Chongqing government's Liberation Army could fight inside Korea. The US refused to recognize it as a government, so Kim Gu and his ministers flew home only in November and December 1945, and only as private individuals.
When and how
Chongqing to Seoul, November 23 and December 2, 1945, on US military aircraft.
How we know
US military government records, Provisional Government documents, and Kim Gu's own account in Baekbeom Ilji.
Debates and open questions
Whether recognizing the exile government would have produced a more unified Korea, or simply deepened factional fights, is a lasting counterfactual.
