Yes, but bear in mind that for the Greeks the Iliad was something between a perfectly true history and the Bible.

As such, it's one of the most sociopolitically important books; it's a list of who was at The Most Important Battle Of All Time, and therefore also a list of which city-states were old and distinguished enough to have taken part. There's evidence that the text was tampered with to add in Athens, which was far too young to have actually sent people. And that's even before you get into Who Sent What and look how powerful Sparta/Corinth/etc/etc was back then, son, you see, you come from a great people! Make us proud!

It also explains the Aeneid. Having a legendary founder (and everyone did, even if the truth was that they'd been founded yesterday by perfectly human people*) who went all the way back to the Iliad lent automatic superiority and historic legitimacy over all those other upstart little city-states.

And so: greatly simplified, it's just a long list of who's better than you. The blue book of Ancient Greek poleis, if you like.

*Aristocratic families also liked to add mythological figures into their genealogies.

I'm sorry if I've misread your tone and lectured you for nothing, or if this is unintelligible. It's two in the morning and I'm insomniac for the second night running, so... yeah.
