IOTL, the Republics of Venice and Genoa ultimately came to dominate maritime trade in the Mediterranean Sea, becoming important regional powers whose influence far outperformed their territorial extent.
However, at other times in Italian history, other maritime republics existed that competed with Genoa and Venice for trade and commercial success. These included Pisa, Amalfi and Ragusa (the latter of which survived even Venice, but failed to match their power), as well as the quasi-independent states of Ancona and Gaeta.
Your challenge is to come up with a suitable POD, no earlier than 800 AD, that leads to the rise of one or more of these other city-states to roughly equal stature of Genoa and Venice at their height. Genoa and Venice are still allowed to become the powers they were in OTL if this fits with your chosen POD(s).
How would the growth of alternative mercantile powers in the Mediterranean affect the history of the region? How would the Byzantines fare without Genoa to support them, or Venice to take them down? Could other cities (Zara? Split?) also become 'maritime republics' in the absence of Genoese or Venetian power? Would the Crusades be severely altered or even butterflied?
Bonus points if anybody can tell me anything about Noli, apparently another maritime republic of which the internet has little to say.
Extra bonus points if anyone knows whether in OTL any of these other cities had commercial colonies and overseas trading posts as Venice, Pisa and Genoa did? Almafitan, Ragusan, Anconine 'empires'?
