Salamis was the turning point in the second Persian invasion, and indeed the Greco-Persian Wars in general. While the battle did not end the Persian invasion, it effectively ensured that all Greece would not be conquered, and allowed the Allies to go on the offensive in 479 BC. A number of historians believe that Salamis is one of the most significant battles in human history. Since Themistocles' long-standing advocacy of Athenian naval power enabled the Allied fleet to fight, and his stratagem brought about the Battle of Salamis, it is probably not an exaggeration to say, as Plutarch does, that Themistocles, "...is thought to have been the man most instrumental in achieving the salvation of Hellas."
