Venice–Genoa Maritime Trade Competition in the 1430s

Timeline

1. 1430–1435Aegean Sea · Aegean SeaVenice's merchant fleet strengthened convoying of bases such as Crete and Nauplion, while Genoa relied on colonial networks like Chios and Galata (across from Constantinople) to contest the transshipment of grain, alum, and eastern goods. Merchants and consuls of both sides frequently clashed over tariffs and berthing rights in the ports.
2. 1433–1437Cyprus · CyprusCyprus, a hub of sugar and entrepôt trade, became a focal point of contention between the two countries' merchant houses and financial networks. Venice expanded warehousing facilities in Famagusta, while Genoese merchants used royal debts and chartered privileges to maintain influence on the island; their rivalry indirectly constrained the foreign policy of the Kingdom of Lusignan.
3. 1436–1439Venice · VeniceThough there was no large-scale war, the two countries eased merchant-ship conflicts through envoy negotiations in Venice and Genoa, and jointly addressed the long-term threat that Ottoman expansion posed to eastern routes. The competitive landscape thus entered a new phase relying more on diplomacy and financial means.
