End of the Venetian-Genoese War of Chioggia, 1378-1381

Timeline

1. 1379Chioggia · Venetian LagoonIn August 1379 a Genoese fleet under Pietro Doria, together with Hungarian and Paduan allied forces, entered from the southern end of the lagoon, captured Chioggia and controlled the Brentello channel, completely surrounding the Venetian mainland; the Republic of Venice faced an existential crisis.
2. 1379–1380Venetian Lagoon · Venetian LagoonOn the night of 22 December 1379 Contarini and the released Vittorio Pisani launched a surprise attack, sinking ships to block Chioggia's inlets and cutting the Genoese garrison off from its home fleet. On 1 January 1380 Carlo Zeno returned with his Mediterranean expedition fleet, turning the siege into a counter-siege.
3. 1380Chioggia · Venetian LagoonOn 12 May 1380 the Genoese relief commander Matteo Maruffo arrived with his fleet at Brentello but failed to break the Venetian blockade. On 24 June, after nearly a year without supplies, Chioggia's garrison surrendered; Venice regained control of the lagoon and won a decisive military victory.
4. 1381Turin · PiedmontOn 8 August 1381, mediated by Savoy's 'Green Count' Amadeus VI, Venice and Genoa signed a peace treaty at Turin, formally ending the War of Chioggia. The treaty required both sides to release prisoners of war, Venice to cede some territory and pay tribute to Hungary, and Tenedos to be demilitarized, marking the end of the two great maritime republics' long rivalry.
5. 1381–1384Adriatic Sea and eastern Mediterranean · Adriatic SeaAfter the treaty, Venice gradually recovered its dominance of Adriatic trade, and Genoese fleets thereafter rarely entered those waters. Hungary gained partial control of Dalmatia, and Venice paid tribute to Louis I. Though both republics were badly weakened, they thereafter effectively divided spheres of influence in the Aegean and eastern Mediterranean, Chioggia becoming the final chapter of the Venetian-Genoese rivalry.
