ROMULUS and REMUS found Rome (traditional). The twin sons of priestess Rhea Silvia, the twins were reputedly fathered by the god of war, Mars. According to the tradition recorded as history by Plutarch and Livy, Romulus served as the first King of Rome. After his death, Romulus was deified as the god Quirinius, the divine persona of the Roman people. He now is regarded as a mythological figure, and it is supposed that his name is a back-formation from the name Rome, which may ultimately have derived from a word for “river”.

No one seems to be interested in what happened to Remus. Can’t find his story anywhere.
