See it on the Korean History map →What happened
After Chun's junta extended martial law and arrested Kim Dae-jung on May 17, students protested in Gwangju. Special forces paratroopers beat and shot protesters and bystanders; on May 21 troops fired on a crowd. Citizens armed themselves, drove the army out, and ran the city for five days until troops retook it on May 27. Official counts list about 165 civilians killed and 76 missing, plus 27 soldiers and police; estimates vary. Koreans call it the 5·18 민주화운동.
Why it matters
It discredited Chun's regime, turned many young Koreans against the US, and became the moral core of the 1980s democracy movement.
How we know
Military and hospital records, survivors' testimony, foreign press footage such as Jürgen Hinzpeter's, the 1996–97 trials, truth commission reports, and May 18 archives on UNESCO's Memory of the World list since 2011.
Still debated
Who ordered troops to fire, the full death toll, the fate of the missing and US foreknowledge are still investigated; claims of North Korean involvement have been rejected by investigators.

The connection
On May 17, 1980, Chun's junta extended martial law nationwide, closed universities and arrested opposition leaders including Kim Dae-jung. Paratroopers sent to Gwangju met student protests with extreme force; when armed citizens drove them out, the army sealed the city and retook it on May 27.
When and how
Gwangju, May 17–27, 1980; special forces paratrooper brigades and the army's 20th Division under the martial-law command Chun controlled.
How we know
Military records, and the 1996–97 trials that convicted Chun of insurrection and murder over Gwangju.
Debates and open questions
Who gave the order to fire on May 21 remains unproven; helicopter gunfire, long denied by Chun, was confirmed by a 2018 defense ministry inquiry and a 2020 court ruling.
▸Gwangju Uprising (May 18 Democratic Movement) fueled June Democratic StruggleWell documented
The connection
Gwangju stripped Chun's government of legitimacy. Through the 1980s students and churches spread hidden photos and foreign footage, and 'the truth about Gwangju' became a rallying demand. Anger also turned on the US, seen as having allowed the troop movements. By 1987 its memory hardened protesters and made the regime wary of another massacre.
When and how
1980–1987; university campuses and Catholic churches, the 1985 student occupation of the US Information Service in Seoul.
How we know
Activists' memoirs, protest slogans and leaflets, and historians who trace a direct line from 1980 to 1987.
Debates and open questions
How much Gwangju's memory, compared with economic growth and a rising middle class, drove the 1987 breakthrough.
