Marino Faliero, and Venice made peace with Genoa on 1 June 1355. Though inconclusive in itself, Venice's exhaustion by this war helped bring about the loss of Dalmatia to Hungary shortly afterwards. Freed of the need for support from Milan, the Genoese brought an end to Milanese rule in 1356. War of 1377–1381 In 1376 Venice bought the strategically positioned island of Tenedos near the Dardanelles from the Byzantine Emperor John V, threatening Genoese access to the Black Sea. This induced the Genoese to help John's son Andronikos IV to seize the throne, in return for the transfer of the island to Genoa, initiating a new war between the two republics. The Genoese failed to take Tenedos from the Venetians in 1377, but gained the support of a coalition of Venice's mainland rivals Hungary, Austria, Aquileia and Padua, although only Padua gave substantial assistance. Venice allied with Milan, whose army threatened Genoa from the landward side, and with the Kingdom of Cyprus, which had been defeated in a war with Genoa in 1373-74 and subjected to Genoese hegemony. A small Genoese fleet led by Luciano Doria invaded the Adriatic in 1378 and defeated the Venetians under Vettor Pisani at Pula in 1379. Having been reinforced, they advanced against Venice under Pietro Doria, Luciano having been killed at Pula. Though failing to break through the defences of the Venetian lagoon, the Genoese captured the port of Chioggia near its southern end, with support from the Paduans on land. In December 1379 the Venetians were able to sink blockships in the harbour of Chioggia, trapping the Genoese fleet inside. Venice was reinforced by the return of a raiding fleet under Carlo Zeno, which had enjoyed exceptional success against Genoese commerce throughout the Mediterranean. A new Genoese fleet was assembled in the Adriatic, but was unable to break through to relieve Chioggia. The forces trapped inside were forced to surrender in June 1380. Fighting continued between the Genoese and Venetian fleets over the ports of the upper Adriatic, but through the mediation of Amadeus VI of Savoy, the two sides negotiated peace at Turin in 1381. Despite the victory at Chioggia, the war had been financially disastrous for Venice, which only secured peace by agreeing to concessions including the evacuation of Tenedos, recognition of Genoese supremacy in Cyprus, the surrender of its principal mainland possession of Treviso, and the payment of an annual
