The two fought about where to build a new city of theirs. Finally, each of them decided to build their own cities where they wanted to.
One day, brother Remus jumped over Romulus' wall into his city and started mocking the fact that his city is very poorly protected. Romulus got mad at this, stabbed and killed Remus.
Haha this city is horrible.
Romulus then became the first ruler of Rome in 753 B.C. and populated his city with criminals and runaway slaves. He then stole women from the Sabine tribe as wives for the criminals and runaway slaves.
This sparked a war between the Sabine tribe and the members of Rome.
After many years of fighting the two came to an agreement and worked together as a part of Rome.
After Romulus' death he was carried up by Mars and was worshipped as the god Quirinus.
