Map of South America, 1904–1923
On 1 July of every year from 1904 to 1923, IntMap’s historical map draws the same 19 names within South 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.

Listed: every name whose outline IntMap draws inside 82°W–34°W, 56°S–13°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.
