Map of Southeast Asia, 1924–1936
On 1 July of every year from 1924 to 1936, IntMap’s historical map draws the same 17 names within Southeast Asia. The borders come from CShapes 2.0 (day by day), then Cliopatria, Seshat Global History Databank (by year) — each drawn only where the records before it are silent.

Borders and names: CShapes 2.0 (Schvitz et al. 2022, icr.ethz.ch/data/cshapes) · CC BY-NC-SA 4.0 + Cliopatria v0.2.1 (Seshat Global History Databank, github.com/Seshat-Global-History-Databank/cliopatria) · CC BY 4.0 · adapted by IntMap: simplified, BC years made astronomical, and the ground OpenHistoricalMap (1689–1885, and from 1886 where CShapes is silent) and CShapes (1886–2019) state removed on their own dates.
Listed: every name whose outline IntMap draws inside 92°E–141°E, 11°S–24°N on this date, with the name the map writes on it. The list is worked out when the site is built, from the same records and the same code the map uses, so it says what the map shows — not more. Names are the source’s own, translated where the source or IntMap’s name table has a translation.
