The Venetian–Genoese Wars were a series of struggles between the Republic of Genoa and the Republic of Venice, at times allied with other powers, for dominance in the Mediterranean Sea between 1256 and 1381. There were four bouts of open warfare, in which the fighting between the two republics took place largely at sea. Even during periods of peace, incidents of piracy and other minor outbreaks of violence between the two trading communities were commonplace. In the first war, in 1256–1270, the Venetians had the better of the fighting, but were unable to prevent the advance of Genoese interests in Byzantium and the Black Sea. The Genoese were overwhelmingly victorious in combat in the second war, 1294–1299, but the conflict ended inconclusively, as did the third, 1350–1355, in which Venice fought in conjunction with Aragon and in which the fighting was more evenly balanced. In the fourth war, 1377–1381, Venice itself was threatened with capture by the Genoese and their allies, and although victorious in the fighting, the exhausted Venetians accepted peace terms which amounted to defeat.

The first full-scale between Genoa and Venice arose from a dispute over prerogatives in Acre, which led to a Genoese attack on the Venetian quarter. The Venetians were supported by the Pisans and Provencals, the Knights Templar and some of the local nobility, while the Catalans, Anconitans, Knights Hospitaller and other local nobles joined the Genoese. A fleet sent from Venice under Lorenzo Tiepolo in 1257 defeated a Genoese fleet off Acre when it arrived in June the next year.
