During the Corinthian War, Sparta had sought to extend its power onto the seas, challenging Persian and Athenian naval dominance. The Achaemenid Empire, allied with Athens and other Greek states opposed to Spartan hegemony, dispatched a fleet under Pharnabazus and the exiled Athenian admiral Conon to confront the growing Spartan naval presence.
In 394 BC, the combined Achaemenid-Athenian fleet under Pharnabazus and Conon engaged the Spartan fleet commanded by the inexperienced Peisander near Cnidus on the southwestern coast of Asia Minor. The Spartan fleet was decisively defeated and largely destroyed, with Peisander killed in the fighting.
The defeat eliminated Sparta's capacity for sustained naval operations and ended its brief bid for maritime supremacy. The victory significantly boosted the morale and strategic position of the anti-Spartan coalition, allowing Conon to subsequently help rebuild Athenian fortifications and restore Athenian influence in the Aegean.
