Suppose that Athens avoids the Sicilian Expedition, thus prevailing with its Delian League intact following a shorter Peloponnesian War; that in later years is only overshadowed as a maritime power by a polis adopting a similar government; and that this democratic hegemony lasts at least four centuries following the PoD (or to the end of OTL's "BCE") -- and JTBC, I'm only looking at the effects of this, not the how (there are threads and TLs on that).
What would the Mediterranean (and surrounding) societies and polities look like in this time -- would it remain more balkanized into polis', or could larger proto-states emerge? What are the chances that any of the powerful full-fledged democracies (Athens, Syracuse, if it survives, etc) might expand their rolls of voting citizens, be they with the metics, the citizen women, or what have you? How would political (and perhaps general) philosophy be altered? And how else might western civilization be fundamentally changed?
