I would like to specify a certain part of my post since I feel like I was little vague there
must have a culture similar to that of OTL Iberia.
By this, I mean something like how Spain was almost completely taken over by the Ummayads and related peoples save for areas like Asturias, only to be slowly retaken by Christendom in the reconquista and the culture that would result from that. So like, Conquistadors equivalents, spanish inquisition equivalents, the middle eastern/north african cultural influence etc.
Which is why I included this little bit.
while having some other Middle-eastern/North African power or even some Byzantine rump state taking the same role in South Italy that the Ummayads did in Iberia.
And when it comes to 'republican city states' that can include Thalassocratic republics like those of Italy proper (Venice, Genoa, Amalfi etc) and communes and alliances of city states like the League of Lombardy.
Though, You can have duchies in the south of the Iberian peninsula like those south of the Papal states IOTL. If You really want, You could even have Peasant republics in the Pyrennes and other Northern Iberian mountains that parallel the Alpine Republics of OTL (I know that they weren't really part of Italy IOTL, I just feel like the Alps and Pyrennes mountain ranges would be affected by this swap as a conequence), though that's probably kinda pushing it, isn't it?
Sorry for being a bother and adding this addendum after the fact, I just felt like I really needed to clarify.
Minus the "republican city states", this is OTL. Much of the basis of the Renaissance comes from the translations of works from Arabic from the Arabic libraries into Latin.

If you mean stuff relating to art...just have contemporary Spanish artists be more famous.
Probably avoid the conquest of the Kingdom of Lombardy by the Franks. That should serve as a reasonable Castile analogue
It just needs Spain not to consolidate. The various Taifas were basically independent.

Interesting.
The hardest bit is probably having city states in Iberia- it’s just not as urbanised as Italy. Taifas small enough might have essentially the same territory as a city state but does it count if it doesn’t have the city council as the highest body of the state?
Apart from that, something of the sort might end up happening in a tl I’ve been mulling over for a while.
I look forward to seeing this timeline.
Urbanism in Spain is possible if it doesn't go Visigothic, which saw a lot of depopulation and people movement out of the urban centers on the Mediterranean coast and in the south. Western Iberia however never really developed in a similar fashion. I think Spain could be an urban conglomeration of city states if the Roman collapse saw essentially a Hispano-Roman aristocracy balkanize power amongst itself and claim different areas based on diocesan boundaries in existence. The Suebi being tucked into Galicia is still probably doable in this timeline but the Visigothic Kingdom is not
So would this Balkanisation happen before or after the Suebi arrive? Also, would the Visigoths be staying in Southern Gaul in such a scenario?
