There is another rationale.
The Persians win various significant battles, including at Marathon, and the occult ideas of the East become more influential.
Also, either an ancient philosopher becomes a geographer, or vice-versa, and his ideas become very influential.
Maps have words and images.
Words and images can have magic power.
Putting those words and images in concrete form (on a map) can manipulate reality.
Having the borders correspond to certain images can have a magical influence on reality.
I don't know if politicians and generals would go along with that, but they've gone along with a lot of other wacky ideas.
The regions of North America are actually administrative districts, part of the Empire of Scotland, England, Ireland and Dominions Overseas. The smaller districts are Indian reservations.
Shall I tell more about this world, or modify the map, or would you rather drop the subject?
