Kingdom of Norway

These are real dates: Kingdom of Norway's founding is recorded in Wikidata, and accepted here only because they agree with the centuries the atlas independently drew it in. Wikidata records more than one founding date; the earliest is shown. No dissolution is recorded, so the closing year below is still the last century the atlas drew — not when it ended. The atlas itself draws the world at one moment in time, not continuously. The strip below covers those snapshots — 900 CE to 900 CE — which sits inside the fuller span above.
