Olynthos, a Greek city on the Khalkidhikí…
379 BCE
Olynthos, a Greek city on the Khalkidhikí (Chalcidice) Peninsula and leader of the Chalcidian (or Chalcidic) League, has become the center of Greek resistance to the power of Athens and Sparta.
Meanwhile, the Spartans, after three years of fighting in order to block Athenian and Chalcidian aid to Thebes, had in 380 BCE starved Olynthus into surrender; in 379 they disband the league. (The Chalcidian cities in a few years, however, will again federate.)
