Map of North America, 1851–1852
On 1 July of every year from 1851 to 1852, IntMap’s historical map draws the same 25 names within North America. The borders come from OpenHistoricalMap (day by day), then Cliopatria, Seshat Global History Databank (by year), then historical-basemaps — each drawn only where the records before it are silent.

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.
