Do we know what Trojans were like? For example their language or Pantheon? And how close was it to Greek culture?
Not to preclude further answers, but I responded to a very similar question here.
It is clear from Hittite texts, however, that the Mycenaeans meddled quite a bit in the affairs of the western Anatolian kingdoms like Troy (ancient WiluĊĦa). I wrote more about this in this post.
