References to strange Trojan allies in the Aeneid

 

From what I know from the arrival of the Indo-European Hattians into Cappodocia to the arrival of the Cimmeranians, the populations remained fairly static in the ethnic/migratory sense. Most of the states in Asia Minor at this time were based on a Hattian elite with an underclass of unknown pre-Hattian locals (interestingly rather similar to the Pharonic civilisation...). It's a massive debate as to who the sea peoples actually were, but they probably were not Hittite (apparently Hittite naval power was pretty much unheard of, so trying to equate the naval invasions into Egypt of the Hykosos and sea peoples with the Northern Hittites is clearly folly), and were called "kazgar" or something like that by the Hittites. The only states that weren't really Hattian insomuch as their ruling class and national culture was concerned were the parts of the Assyrian empire that pushed into Asia minor, the proto-Armenian kingdom of Urartu and some of the smaller vassal kingdoms. Much culture in Asia Minor remined stagnant because of the terrain, and generally it wasn't as quickly fluctatuting as it was in Mespotamia - actually even in the 6th century BC, the Lydians and other "pseudo-Greek" states that tried to resist Cyrus's advance were actually decended from the Hattian elite that ruled the Hittite empire. As can be seen, in contrast to mesopotamia, which had already several massive ethnic changes in this time.

 

...As for Greece, the only dispora that I'm aware of is around the 900s-700s when many Greeks fled from the mainland from the advancing Dorians. They majority of states left on the Greek mainland weren't actually Greek as in the original inhabitants of Greece from the Cyclidaic culture to the Myceanean culture - Sparta, the Locrians, Aetolians and Phocians were in all probability decended from Dorian tribes, and the Athenians nobody knows about. It could be said that the Myceanean culture's people fled to Asia minor, but from what's been unearthered it seems like it was just in trickles rather than one mega-exodos, and in any case, the Dorians weren't (at least as far as I'm aware...) one unified people with one unified strategy for attacking the Myceanean cities in Greece, and in any case, this is actually past the time that the Trojan war supposedly was, and the forces that attacked Troy were almost certainly Myceanean.

 

as well as possibly the Etruscans, who were believed to be from Phygria

 

Another interesting link to classical literature - sounds a little like "the Aeneid", doesn't it? The Etruscans - in many respects the predecessors of the Romans - were, as you said, supposedy Phygrian in origin. I doubt if Virgil actually saw it in this way, but as far as we know, the Mycenean culture had a war with a Hattian culture somewhere in Western Asia minor (although the site of Troy has been more or less decided, it's still a bit of a wonky area). Both Virgil and Homer both mention Phygrian allies in their poems, so this really does look like we've got something here.

 

...incidentally, Another link to some eastern allies - in book 1 of the Aeneid, when the bribed Aelous has used his winds to attack the Aenas's Trojan fleet, Aeneas says that he saw a shipfull of Lycians (I can't remember the leaders' name...) drown. It's surely not a coincidence that Lycia was more or less it's own independent state, and was actually often caught between the Hittite empire and their friend/rival Arzawas in the West of Asia Minor above the little Lycian penninsula. This really isn't a coincidence...
