Romulus and Remus were twin boys who were abandoned as infants but cared for by a she-wolf. They grew up to learn the truth of their origins and overthrew the king who had left them to die. The twins disagreed on where to build a new city, with Romulus seeing an omen favoring the Palatine Hill while Remus favored the Aventine Hill. In the argument that followed, Romulus killed his brother Remus and went on to become the first King of Rome.
