Battle of Settepozzi
The Battle of Settepozzi was fought in the first half of 1263 off the Greek island of Settepozzi (the medieval Italian name for Spetses) between a Genoese–Byzantine fleet and a smaller Venetian fleet. Genoa and the Byzantines had been allied against Venice since the Treaty of Nymphaeum in 1261, while Genoa, in particular, had been engaged in the War of Saint Sabas against Venice from 1256.
