Battles of the Theban-Spartan War, 379-371
This map shows the main battles of the Theban-Spartan War of 379-371 BC, a
conflict that started with the Thebans expelling a Spartan garrison and ended
with Spartan military power suffering a blow from which it never recovered.
After being expelled from Thebes the Spartans sent several expeditions into
Boeotia to try and restore their control. The Theban campaign of 378 and Theban
campaign of 377 both ended with the Spartans unable to reach Thebes, while the
campaign of 376 was stopped at Cithaeron, on the borders of Boeotia. In the
same year the Athenians won their first significant naval victory in their own
name since the Great Peloponnesian War at Naxos. 375 saw the Spartans hoplites
suffer a rare defeat at Tegyra, and their fleet a more common defeat at
Alyzeia. A Spartan attempt to capture Corcyra (373-372 BC) ended in failure and
peace negotations began. Eventually everybody but Thebes made peace, but the
Spartans then suffered a crushing defeat at Leuctra, the first defeat for their
main hoplite army.
