The Dardanoi (Greek: Δάρδανοι; its anglicized modern terms being Dardanians or Dardans) in classical writings were either the same people as, or a people closely related to, the Trojans, an ancient people of the Troad, located in northwestern Anatolia. The Dardanoi derived their name from Dardanus, the mythical founder of Dardania, an ancient city in the Troad. Rule of the Troad was divided between Dardania and Troy. Homer makes a clear distinction between the Trojans and the Dardanoi. […]
The Royal House of Troy was also divided into two branches, that of the Dardanoi, and that of the Trojans (their city being called Troy, or sometimes Ilion/Ilium). The House of the Dardanoi (its members being the Dardanids, Greek: Δαρδανίδαι; Latin: Dardanidae) was older than the House of Troy, but Troy later became more powerful. Aeneas is referred to in Virgil’s Aeneid interchangeably as a Dardanian or as a Trojan, but strictly speaking, Aeneas was of the branch of the Dardanoi. Many rulers of Rome claimed descent from Aeneas and the Houses of Troy and Dardania.
