What if:
- Charlemange - in addition to his real-life conquests- also conquered all of Spain and Portugal (including the Muslim-held provinces)
OR
-Spain (and maybe also Portugal, optionally) was conquered by the Kingdom of France before 1492
The questions:
- Would it have a serious impact on later history, such as the Rise of Nationalism? Would distinct Spanish and Portuguese national idenities develop, or would they end up being completely assimilated into French?
- How much would be Spanish and Portuguese languages effected?
- Would it prevent America from getting discovered?
- Would it end up provoking a Jihad against Iberia?
