Lysander

Lysander (died 395 BC) was a Spartan admiral (navarch) who commanded the Spartan fleet in the Hellespont. He defeated the Athenians at Aegospotami in 405 BC. The following year, he was able to force the Athenians to capitulate, bringing the Peloponnesian War to an end. He then played a key role in Sparta's domination of Greece for the next decade until his death at the Battle of Haliartus. Lysander's vision for Sparta differed from most Spartans; he wanted to overthrow the Athenian Empire and replace it with Spartan hegemony.
