How these dates were made
Real dates from Wikidata, checked against the atlas.
These are real dates: Mercia's founding and dissolution are recorded in Wikidata, and accepted here only because they agree with the centuries the atlas independently drew it in. The atlas itself draws the world at 2 moments in time, not continuously. The strip below covers those snapshots — 800 CE to 900 CE — which sits inside the fuller span above.
Elsewhere in Europe at the time
Records whose own span overlaps this one, found by the same test the canvas draws with. The bar under each card is where it sits inside this one.
