Long ago, there was a woman named Rhea Silvia who gave birth to two twin boys. They were sons of Mars, the god of war. Rhea Silvia's jealous uncle Amulius overthrew King Numitor and forced Rhea to become a Vestal Virgin.
So Amulius threw Romulus and Remus into the Tiber River. Luckily, the river washed them onto the shores of Palatine Hill.
The babies will never survive in the river and with them gone, I will be king! Muhahahahah!
There, a she-wolf suckled and fed them until a shepherd found them. The shepherd raised them like his own children.
Once they found out about their true identity, they fought Amulius and restored Numitor as king.
Romulus and Remus decided to build their own city. Romulus wanted to build the city on Palatine Hill, but Remus wanted it to be on Aventine Hill. They fought and Romulus ended up killing Remus.
NO, PALATINE HILL!
Having killed his twin brother, Romulus based the city on Palatine Hill and decided to name it 'Rome', after his name.
Hmmmmm, what should I name this new city? I know! Rome! After me, Romulus!
So that, is how the great city of Rome was founded.
