Romulus and Remus were twin brothers and their dad was the king
The twin brothers uncle threw them into the Tiber and hoped they would drown the crazy uncle (Amulius) threw them twins brothers into the Tiber river because Amulius wanted to become ruler instead of the twin brothers so Amulius threw them in Tiber so they couldn’t become ruler so he tried to kill them
When the boys where on the river the boys get rescued by she-wolf
Later ended up with shepherd Faustulus and looked after them until they grew up
The boys later found out that their dad was the ruler and came back home when the got home the brothers decided to kill Amulius and Remus and Romulus became ruler
The boys decided to build a city of their own and couldn’t decide where to put it Remus favored the Aventine Hill but Romulus wanted to use the Palatine Hill they couldn’t reach an agreement and so each began to build his city enclosed with walls one day Remus visited his brother city and made fun of his wall by jumping over it and saying how easily it could be breached.
His brother got annoyed and killed Remus and said he would kill anyone who mocked his city or tried to break through the Rome walls and Romulus became the first ruler in Rome.
