Dardanus was a son of Zeus and Electra, the mythical ancestor of the Trojans, and through them of the Romans. Originally a king in Arcadia, Dardanus migrated to Samothrace, and then to Asia, where King Teucer gave him the site of his town, Dardania. He married a daughter of Teucer, and his grandson was the eponymous hero Tros, who removed his grandfather's Palladium to Troy.
