What other country would have them? Leon didn't, so Euskara was one of the closest to it.
Fair enough, but I think it is unrealistic for Euskara to have all of them, maybe just Madeira (or other) and transfer the others to Leon?
My proposal for Europe:
Cleaned up the borders for Normandy slightly
Gave the Franks those random bits that Denmark and Normandy took
Respected Denmark's initial claim for that island by Sweden
Transferred some of the Basque islands to Leon
Massilia - Marseille
Spain - Castile
The problem is that it hasn't been Massilia since Roman times. Why not call it Provence, but some Italianised version of the name.
Just checking: you were talking about the pink country, right?
