'AHC: Someone other than Athens, Sparta or Thebes becomes the dominant Ancient Greek polis.'
The obvious candidate would be Corinth. POD could be as (relatively) recent as the Peloponnesian War. Specifically, if Sparta agrees to destroy Athens, Corinth profits imnensely, and will later be in an obvious position to challenge Sparta for hegemony. (In OTL, that was true of Athens, too, so for Sparta it's not unthinkable to go hard against Athens.)
Since various lesser poleis may welk consider Corinth a more palatable hegemon than thry did Athens in OTL, the anti-Spartan coalition may well end up sturdier-- leading to a Spartan defeat and a Greece thst is unified with Corinth as its foremost city and nominal hegemon.
