The Siege of Melos occurred in 416 BC during the Peloponnesian War, a war fought between Athens and Sparta. Melos is an island in the Aegean Sea roughly 110 km east of mainland Greece. At the time it was populated by Dorians. Though the Melians were of the same ethnic group as the Spartans, they chose to remain neutral in the war. Athens invaded Melos in 416 BC and demanded that the Melians surrender and pay tribute to Athens, or face annihilation. The proud Melians refused, and after a siege the Athenians captured their city, slaughtered the men, and enslaved the women and children.
