With a POD no earlier than 751, come up with a scenario that could make this map historically accurate.
Basically, make Andalusia into a Christian kingdom stronger than the other kingdoms in Iberia, which actually claims the "Empire of all Spains" title, yet, has not actually united the peninsula.
Bonus points: make the northern kingdoms into Spain's "Andalusian March" against the Franks. An exact opposite Frankish March.
