In Roman mythology, Amulius was king of Alba Longa who ordered the death of his infant, twin grandnephews Romulus, the eventual founder and king of Rome, and Remus. He was deposed and killed by them after they survived and grew to adulthood.

Romulus was the legendary founder and first king of Rome. Various traditions attribute the establishment of many of Rome's oldest legal, political, religious, and social institutions to Romulus and his contemporaries. Although many of these traditions incorporate elements of folklore, and it is not clear to what extent a historical figure underlies the mythical Romulus, the events and institutions ascribed to him were central to the myths surrounding Rome's origins and cultural traditions.
