After aeneas returned from the underworld what did he and the trojans undertake

After visiting his father Anchises in the underworld, Aeneas sets off from Greece with the Trojans to Italy. Anchises had shown him the significance of his journey there. He was to explicate his lineage there so that the Trojans through their descendant Romulus, would found the city of Rome. He is also aware that Caesar would also come from his lineage through Ascanius. As such, the Trojans would rule the world through Caesar.

Good luck : )
