Twin boys were born by a princess. But their jealous king put them on a river hoping that they would die and not be able to take over the throne one day.
The twin boys were then found by a mother wolf. She raised them as if they were her own. A Shepard came along the family one day and saw the boys and took them to raise them as his own.
One day Remus was captured and taken to the king. He found out his true identity. Romulus went to go rescue his brother. In the end they killed the king but left the throne. They did this because they wanted to found their own city.
The two brothers wanted to make a city of their own but they wanted it in different places of Rome. They agreed that the first to receive a sign from the gods would get to choose where to build the city. Remus got six signs and Romulus got twelve signs.
Romulus thought that he won so he started building a wall. Remus was making fun of Romulus because he said it was easy to get past it. Romulus was so angry that he killed his own twin brother and took the throne.
With Remus dead Romulus took the throne and was the founder of Rome. Rome became one of the most powerful cities in the world.
