Map of North America, 1918–1922

On 1 July of every year from 1918 to 1922, IntMap’s historical map draws the same 10 names within North America. The borders come from CShapes 2.0 (day by day), then OpenHistoricalMap (day by day), then Cliopatria, Seshat Global History Databank (by year) — each drawn only where the records before it are silent.

Names on the map

Source and method

Borders and names: CShapes 2.0 (Schvitz et al. 2022, icr.ethz.ch/data/cshapes) · CC BY-NC-SA 4.0 + OpenHistoricalMap (openhistoricalmap.org) · CC0 1.0 · adapted by IntMap: the admin_level=2 relations in force from 1886, less the ground CShapes states on its own dates + 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 170°W–52°W, 24°N–72°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.
