Republic of Korea (KOR)East Asia, AsiaMay 18, 1980
Event Summary
On May 18, 1980, citizens of Gwangju, South Korea rose up against the military government of General Chun Doo-hwan, who had seized power in a December 1979 coup and ended the brief "Seoul Spring" democratic opening. Protesters, mostly young citizens, formed a civilian militia and held control of the city for about a week against martial-law troops. The uprising was suppressed when military tanks advanced into Gwangju on May 27, 1980, with the army carrying out what sources describe as indiscriminate killing of civilians, though the exact death toll remains unknown.
The military government suppressed domestic media coverage of the massacre, but foreign journalists exposed its extent, and the event became a pivotal, memorialized turning point in South Korea's democratization movement, later commemorated with a national cemetery in Gwangju.

Editorial Note
Sources agree on the broad narrative (dates May 18-27, 1980; Chun Doo-hwan as the target; suppression by military tanks) but both Britannica and the Library of Congress guide note that exact casualty figures are disputed/unknown. Did not separately verify Wikipedia's specific footnoted sources this session; instead relied on Britannica and a Library of Congress research guide, both fetched directly and treated as independent VERIFIED sources. | Re-fetched both cited source URLs (Britannica "Gwangju Uprising" and LOC guide "Kwangju/Gwangju Uprising (1980)") and cross-checked all 7 VERIFIED facts plus target_leader and summary. Both pages are real and their content substantively supports every claim: dates (May 18-27, 1980), mass protest/repressive policies framing, civilian militia formation, Chun Doo-hwan's role in the Dec 12 1979 coup and military response, Park Chung Hee assassination and Seoul Spring, tanks quelling the uprising after six days, unknown casualty count with indiscriminate killing, media suppression exposed by foreign journalists, 'pivotal moment' framing, and the May 18 National Cemetery (confirmed via Britannica image caption). Minor cosmetic issues noted but not corrected: (1) fact 3's 'quote' field splices two separate LOC sentences into one continuous-looking quotation with slightly altered wording ('civilian militia' vs 'militia', 'led the military response' vs 'deployed military forces to suppress the protest') -- a paraphrase presented as verbatim, though the underlying claim is accurate and source-backed; (2) fact 7 cites both Britannica and LOC in source_name but source_url only points to Britannica, even though the media-suppression/foreign-journalist claim actually comes from LOC (which was independently verified). Neither issue rises to fabrication or unsupported claims, so no downgrade was applied. No CHAIN-labeled facts existed to check against Wikipedia. No dead links, no invented sources, no summary claims lacking a corresponding sourced fact.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: General Chun Doo-hwan, leader of the South Korean military government / martial law authorities.
Baseline coding: Coup attempt failed to remove the incumbent. Recorded leader fate: remained in office; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
