King Amulius sent the twin babies Remus and Romulus adrift in the Tiber River to drown, fearing they would inherit his throne. However, the river god Tiber saved them and a she-wolf Lupa found and nursed them. A shepherd named Faustulus then adopted the twins. As adults, they learned of their royal heritage and co-founded the city of Rome, but argued over its name and Remus was killed. Romulus went on to rule Rome for 37 years until he mysteriously disappeared, leading Romans to believe the gods had taken him.
