War of Chioggia in the context of "Treaty of Turin (1381)"

Tenedos (Greek: Τένεδος; pronounced [ˈteneðos]; Latin: Tenedus), or Bozcaada in Turkish, is an island of Turkey in the northeastern part of the Aegean Sea. Administratively, the island constitutes the Bozcaada district of Çanakkale Province. With an area of 39.9 km (15 sq mi), it is the third-largest Turkish island after Imbros (Gökçeada) and Marmara. In 2022, the district had a population of 3,120 inhabitants. The main industries are tourism, wine production and fishing. The island has been famous for its grapes, wines and red poppies for centuries. It is a former bishopric and presently a Latin Catholic titular see.

Tenedos is mentioned in both the Iliad and the Aeneid, in the latter as the site where the Greeks hid their fleet near the end of the Trojan War in order to trick the Trojans into believing the war was over and into taking the Trojan Horse within their city walls. Despite its small size, the island was important throughout classical antiquity due to its strategic location at the entrance of the Dardanelles. In the following centuries, the island came under the control of a succession of regional powers, including the Persian Empire, the Delian League, the empire of Alexander the Great, the Attalid kingdom, the Roman Empire and its successor, the Byzantine Empire, before passing to the Republic of Venice. As a result of the War of Chioggia (1381) between Genoa and Venice the entire population was evacuated and the town was demolished. The Ottoman Empire established control over the deserted island in 1455. During Ottoman rule, it was resettled by both Greeks and Turks. In 1807, the island was temporarily occupied by the Russians. During this invasion the town was burnt down and many Turkish residents left the island.

The Republic of Venice, officially the Most Serene Republic of Venice and traditionally known as La Serenissima, was a sovereign state and maritime republic with its capital in Venice. Founded, according to tradition, in 697 by Paolo Lucio Anafesto, over the course of its 1,100 years of history it established itself as one of the major European commercial and naval powers. Initially extended in the Dogado area (a territory currently comparable to the Metropolitan City of Venice), during its history it annexed a large part of Northeast Italy, Istria, Dalmatia, the coasts of present-day Montenegro and Albania as well as numerous islands in the Adriatic and eastern Ionian seas. At the height of its expansion, between the 13th and 16th centuries, it also governed Crete, Cyprus, the Peloponnese, a number of Greek islands, as well as several cities and ports in the eastern Mediterranean.

The islands of the Venetian Lagoon in the 7th century, after having experienced a period of substantial increase in population, were organized into Maritime Venice, a Byzantine duchy dependent on the Exarchate of Ravenna. With the fall of the Exarchate and the weakening of Byzantine power, the Duchy of Venice arose, led by a doge and established on the island of Rialto; it prospered from maritime trade with the Byzantine Empire and other eastern states. To safeguard the trade routes, between the 9th and 11th centuries the Duchy waged several wars, which ensured its complete dominion over the Adriatic. Owing to its participation in the Crusades, Venice increasingly penetrated into eastern markets and, between the 12th and 13th centuries, managed to extend its power into numerous eastern emporiums and commercial ports. The supremacy over the Mediterranean Sea led the Republic to the clash with Genoa, which lasted until the 14th century, when, after having risked complete collapse during the War of Chioggia (with the Genoese army and fleet in the lagoon for a long period), Venice quickly managed to recover from the territorial losses suffered with the Treaty of Turin of 1381 and begin expansion on the mainland.

The Venetian–Genoese Wars were four conflicts between the Republic of Venice and the Republic of Genoa which took place between 1256 and 1381. Each was resolved almost entirely through naval clashes, and they were connected to each other by interludes during which episodes of piracy and violence between the two Italian trading communities in the Mediterranean Sea and the Black Sea were commonplace, in a "cold war" climate.

Starting in the 11th century, Venice and Genoa had built commercial empires which, in the 13th century, became thalassocracies so solid as to oust the other maritime republics and to make the two cities privileged interlocutors of state structures such as the Byzantine Empire, the Kingdom of Hungary, etc. In the second half of the 13th century the tensions between Venice and Genoa, exacerbated by the Venetian control over Constantinople following the Fourth Crusade, exploded. The first conflict, known as the War of Saint Sabas (1256-1270), was a Venetian victory, though it did not undermine the growing Genoese power in Constantinople and the Black Sea. The second conflict (1294-1299) recorded a revenge for the Ligurians, with significant military victories. After a temporary alliance against the Mongols during the siege of Caffa (1346), Venice and Genoa clashed again in the War of the Straits (1350-1355), during which Venice dragged in the Kingdom of Aragon, Genoa's emerging Tyrrhenian rival. This third war again ended in stalemate with a Genoese military victory at great cost. The fourth conflict, the War of Chioggia (1377-1381), saw Venice surrounded by various fronts, with the Genoese reaching the entrance to the Venetian Lagoon, but, with an enormous war effort, Venice achieved the final victory, saving the city from destruction, even without a debilitating economic outlay. Acts of piracy between the Venetians and Genoese (subject to French control in the meantime) continued until the Venetian victory at the Battle of Modon (1403). Thirty years later, the two republics faced each other again in the Battle of San Fruttuoso (1431), but in the context of the Wars in Lombardy and with Genoa then subject to the Visconti of Milan.
