A stolen slave and a missing treasure sparked a sixteen-year war for Mediterranean power.
When an Ottoman commander’s slave fled to a Venetian fortress with a massive fortune, the resulting diplomatic standoff triggered the first major conflict between the Republic of Venice and the rising Ottoman Empire. This brutal struggle reshaped the map of Greece and Albania, testing the limits of maritime power.
The conflict, spanning 1463 to 1479, was ignited by a minor incident involving an Albanian slave who escaped to the Venetian-held fortress of Coron with 100,000 silver aspers. When Venice refused to return the fugitive, who had converted to Christianity, the Ottomans used the refusal as a pretext for war. While Venice had long preferred trade over confrontation, the influence of Cardinal Bessarion and the advocacy of Vettore Cappello eventually pushed the Senate to declare war on 28 July 1463.
The war was characterized by shifting alliances and intense sieges. Pope Pius II attempted to organize a new Crusade, securing support from Hungary and Burgundy, but the coalition struggled to maintain momentum. In the Morea, the Venetians faced a swift Ottoman response led by Mahmud Pasha, who razed the strategic Hexamilion wall. Despite the efforts of commanders like Sigismondo Malatesta and the naval leadership of Vettore Cappello, Venice suffered significant losses, including the fall of the island of Negroponte in 1470 after a bloody siege.
The conflict also devastated the Albanian resistance. The Ottomans constructed the fortress of Elbasan in just 25 days to bisect the region, isolating the forces of Skanderbeg. Following Skanderbeg's death, the Ottomans systematically subdued the remaining strongholds. The war finally concluded with the Treaty of Constantinople on 25 January 1479, where Venice ceded Shkodër and other territories. The Despotate of Epirus, left abandoned by its former allies, was subsequently conquered by the Ottomans, who sought to establish a staging ground for future invasions of Italy.
