The world in 400

On 1 July 400, IntMap’s historical map draws 120 names across the world. The borders for this date come from Cliopatria, Seshat Global History Databank (by year), then historical-basemaps — each drawn only where the records before it are silent. It also draws 152 outlines whose name the record does not give for this date.

World map on 1 July 400: the borders IntMap’s historical map draws on that date, from Cliopatria, Seshat Global History Databank (by year), then historical-basemaps — each drawn only where the records before it are silent.
Drawn when the site is built from the same records and the same code the map uses, on 1 July 400, in the Equal Earth projection. The picture is simplified for display only: each outline is reduced to about one pixel at this size, and outlines smaller than a pixel are left out of the picture — the map itself draws every one of them in full. Grey is land on which no record states a polity on this date (today’s coastline, Natural Earth 1:110m).

Why this year has a page

The historical-basemaps atlas drew a world sheet for this year.

Names on the map

As the map labels them, largest first by the area of the outline drawn. Areas are of the drawn outline, rounded, and approximate. The record column says which record draws the outline; a Wikidata item is given where the record links one.

What changed since 300

Names counted are those the records date to the year or the day (CShapes, OpenHistoricalMap, Cliopatria). Outlines filled from the nearest historical-basemaps sheet are counted only when both years are years that sheet was drawn for — otherwise the change would be the switch between two sheets, not a change in the world. Names are compared as written, so a polity a record names differently in the two years (Carthaginian Empire, then Carthage) is in both lists.

Sources and method

Borders and names: 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 + aourednik/historical-basemaps (github.com/aourednik/historical-basemaps) · GPL-3.0 · adapted by IntMap: each sheet before 1886 less the ground OpenHistoricalMap and Cliopatria state at that sheet's year.

Which years have a page is worked out when the site is built, from three rules applied to the records themselves: every year the historical-basemaps atlas drew a world sheet for; every year whose change from the year before (names the dated records begin or stop drawing) is in the top 5% of all such year-to-year changes since the dated records begin, leaving out the years where one record hands over to another; and every year of a geopolitical, war or revolution event in the dated events index, up to the last year the border records cover (2019).

On each year the map is read on 1 July, the instant the app’s own year links open on. Names are the source’s own, translated where the source or IntMap’s name table has a translation. A name is what a record draws there, not a verdict of history.
