The Battle of the Echinades was fought in 1427 among the Echinades islands off western Greece between the fleets of Carlo I Tocco and the Byzantine Empire. The battle was a decisive Byzantine victory, the last in the Empire's naval history, and led to the consolidation of the Peloponnese under the Byzantine Despotate of the Morea.
