He was sent out to drown Romulus and Remus but he couldn't do it so, he just sent out them out in the basket
They were floating in the basket along the water and a she-wolf came and nursed Romulus and Remus.
Until a shepherd and his wife discovered, rescued, and raised Romulus and Remus the she-wolf nursed them .
When Romulus and Remus became older they wanted to found a city near where the she-wolf found them but they couldn't agree
Romulus wanted to found the city on the Palatinate Hill while, Remus wanted to found the city on the Aventine Hill. They continued fighting so they visited an oracle , it said whoever saw more birds first that is where they will build their city
Romulus started to build his city anyway, Remus began to mock Romulus . Remus then jumped over his wall to show how easy it was to cross. Romulus became angry and killed his brother making Romulus the sole founder of Rome.
