Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many died on 12.12?
Shooting in Seoul that night was limited; it was not a battle like 1950. The large death ledger is Gwangju in May 1980 -- hundreds in official counts, higher in civic estimates.
Who was Hanahoe?
A secret fraternity of officers, many from the 11th class of the Korea Military Academy, including Chun and Roh Tae-woo. It operated inside the formal army.
What was 10.26?
The 26 October 1979 assassination of President Park by Kim Jae-gyu, his intelligence chief -- the vacuum 12.12 filled.
How does Gwangju connect?
17 May 1980 expanded the new military's control; Gwangju resisted and was crushed. 12.12 is the December preface to May.
Were Chun and Roh tried?
Yes, in the mid-1990s, for mutiny and for Gwangju. Sentences were later remitted -- a legal and political afterlife.
Seoul: Army HQ, DSC, the river crossings of a past night -- named as history.
Gwangju: May 18 cemetery as the required second map.

Portrayals
Chun Doo-hwan biographies
The usual English doorway into 12 December 1979 coup: The centre of 12.12 and of the Fifth Republic. Convicted in the 1990s; a contested death-and-memory figure after 2021.

The paired doorway: Moved a key division on 12.12; later president (1988-93) and convicted alongside Chun.
School survey chapters
Where 12 December 1979 coup (12 December 1979 (night of the seizure; 17 May 1980 and Gwangju follow)) is a paragraph or a unit in US/UK/AU/CA -- often thinner than Seoul: Army HQ, Hanahoe networks, after Park Chung-hee's assassination local hours.
Local museums / sites in Seoul: Army HQ
Thicker than the English paragraph. Trials and film is the usual late pilgrimage caption.
Feature film / television
If 12 December 1979 coup has a visual canon, it probably outruns the monographs. Treat film as memory, not as a log.
Korean civic halls and curricula
12 December 1979 coup belongs in Seoul classrooms and the War Memorial circuit -- a civic file, not an English afterthought.
Rituals
1979-10-26 / 2010s-20s dates
The usual ritual poles of 12 December 1979 coup: Park assassinated and Cinema / civic memory.
Museum and cemetery wreaths
Official and family rites at sites in Seoul: Army HQ, Hanahoe networks, after Park Chung-hee's assassination. Yun Bo-seon / civic opposition is often the civilian or corrective name on the plaque.
Classroom minutes
Where 12 December 1979 coup is on the syllabus -- in Anglophone schools often beside 11 November or a Second World War unit, not always beside Seoul: Army HQ, Hanahoe networks, after Park Chung-hee's assassination's own calendar.
Sayings
English maps that only say "Kwangju 1980" are missing December.
A Korean civic atlas already knows this; this English page exists to catch up without becoming a playbook.
