Romulus and Remus were born, but their mother left them. A wolf found the brothers, and looked after them, giving them milk for example.
When the brothers grew older, they explored a lot, and found a piece of land which would be fantastic for building a large city on.
Romulus and Remus built the city, (Although it didn’t have a name at that point). There was however one huge problem; which of the brothers would rule the city as king?
The brothers tried to decide who would rule the city, but eventually they started fighting.
Romulus eventually won the close fight to the death against Remus, so he became the king of the new city.
Romulus decided to name the city after him. He called it Rome.
