1- it depends on the manner of the victory and it's follow up, but I suppose it is reasonable that there might be a TL where the Genoese fleet gets almost destroyed and the Pisans manage to devastate Genoa's port and it's naval supplies. That said it seems to me that Genoa had better naval manpower reserves and a slightly more stable leadership (see the infamous Count Ugolino which had a very ambiguous role in Pisa's leadership).
That would certainly set Genoa at a huge disadvantage in the short term, and make Pisa the western Mediterranean port of choice. Perhaps Pisa could match Genoese manpower reserves if they an absorb (as others have said) Lucca or Siena or even Florence (i.e. include more of Tuscany)?
2- I think Pisa would have wanted hegemony over Corsica and Sardinia and there would be long negotiations about the fate of the prisoners.
According to this video (
3- they would have clearly been quite stronger in their confrontations with Venice and could maybe have carved an Andrea of influence on the near East.
Did the Venetians and Pisans ever actually come to blows in the way Genoa and Venice did? My understanding was that Venice and Pisa were able to negotiate their spheres of influence in the Mediterranean relatively peaceably, possibly due to their similar antagonism with Genoa. Perhaps if Genoa is permanently out of the picture, Pisa simply takes its place as a rival of Venice?
4- this seems too much however: as I said before the Venetian lagoon is too much of a good strategic location for a significant naval power not to develop there (maybe I am being too deterministic here but I don't think Zahra or Ragusa could ever take Venice's place. Aquileia and Grado however might have if Aquileia hadn't been devastated leading to the founding of Venice).
IOTL, Ragusa used its position as a satellite of Hungary and/or the Ottomans as an advantage, and transported its goods from Ragusa to Ancona and thence overland to Florence, as a means of bypassing the Venetian lagoon. While Ancona's harbour is certainly no match for the lagoon, could alternative routes similar to the Ragusa-Ancona relationship develop if Venice experiences a serious enough setback? Could Ancona's harbour be improved to compete with Venice?
Noli was an autonomous region within the Marquisate of Finale. The land covered about a third of the present day Ligurian region within Italy, Noli was an "independent" trade city under the Marquisate up until 1265 when the land was split into three regions, one that remained independent until 1602 when Spain took it over, one that was absorbed by Moneferet and the other that was under the protection of Milan? (It had the support of Milan for over a century but no direct proclamation of protection seemed to be issued) After 1535, Noli was allied with Genoa.
Thank you, that was very interesting
Could Pisa somehow gain dominance over Florence and/or Sienna? Could the rest of Tuscany act like the equivalent to the Venetian hinterland?
I think this may be the only way Pisa can match Genoa's OTL performance. Florence might be a difficult nut to crack, but Lucca and/or Siena could be easier to absorb. Not sure how their inclusion could be achieved, however.
Ragusa was supposed to acquire a tiny merchant Empire in exchange for its assistance during the Crusade of 1444; but the failure of the crusade put an end to these ambitions.
I don't think the acquisition of a mere 2 or 3 remote ports/colonies would have propelled them to greatness. But who knows, every empire has to start somewhere. Perhaps it would have allowed them to deal with Venice and Genoa as a slightly more equal partner and make further gains from the rivalry of these two giants.
I thought Ragusa was able to establish its own merchant colonies in the Ottoman Empire after the Venetians/Genoese were evicted, due to its preferential treatment? That was later, of course. Was Ragusa not regarded as an equal to Genoa and Venice? I thought the Ragusans ended up in a pretty good place by the end, relatively speaking.
