The end of the Peloponnesian War left Sparta the master of Greece, but the narrow outlook of the Spartan warrior elite did not suit them to this role. Within a few years the democratic party regained power in Athens and in other cities. In 395 BC the Spartan rulers removed Lysander from office, and Sparta lost her naval supremacy. Athens, Argos, Thebes, and Corinth, the latter two former Spartan allies, challenged Sparta's dominance in the Corinthian War, which ended inconclusively in 387 BC. That same year Sparta shocked the Greeks by concluding the Treaty of Antalcidas with Persia. The agreement turned over the Greek cities of Ionia and Cyprus, reversing a hundred years of Greek victories against Persia. Sparta then tried to further weaken the power of Thebes, which led to a war in which Thebes allied with its old enemy Athens.

Then the Theban generals Epaminondas and Pelopidas won a decisive victory at Leuctra (371 BC). The result of this battle was the end of Spartan supremacy and the establishment of Theban dominance, but Athens herself recovered much of her former power because the supremacy of Thebes was short-lived. With the death of Epaminondas at Mantinea (362 BC) the city lost its greatest leader and his successors blundered into an ineffectual ten-year war with Phocis. In 346 BC the Thebans appealed to Philip II of Macedon to help them against the Phocians, thus drawing Macedon into Greek affairs for the first time.

The Peloponnesian War was a radical turning point for the Greek world. Before 403 BC, the situation was more defined, with Athens and its allies (a zone of domination and stability, with a number of island cities benefiting from Athens' maritime protection), and other states outside this Athenian Empire. The sources denounce this Athenian supremacy (or hegemony) as smothering and disadvantageous.

After 403 BC, things became more complicated, with a number of cities trying to create similar empires over others, all of which proved short-lived. The first of these turnarounds was managed by Athens as early as 390 BC, allowing it to re-establish itself as a major power without regaining its former glory.
