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.

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.
