I want to know the answer to the following question:
When was the Peloponnesian War?
All the background I'm provided with is that "Spartan hegemony was succeeded by a Theban one after the Battle of Leuctra (371 BC), but after the Battle of Mantinea (362 BC), all of Greece was so weakened that no one state could claim pre-eminence.". Is that enough to answer the question?
