Which body of water did Venice and Genoa use?

Venice and Genoa are both located on the northeastern and northwestern coasts of Italy, respectively, and they primarily used the Adriatic Sea and the Ligurian Sea for trade and transportation. The Adriatic Sea served as a crucial maritime route for Venice, facilitating its extensive trade networks, while the Ligurian Sea was vital for Genoa's maritime commerce. Both cities leveraged their strategic coastal positions to become powerful maritime republics during the Middle Ages and the Renaissance.
