Remus an Romulus were twin brothers born to Rhea Silvia
Amulius and Numitor had ordered Rhea to be a virgin, but she was impregnated by Mars, the God of War. Fearing that the twins would take over the throne, Amulius had tossed them into the river
Romulus built a wall around his mountain, and Remus jumped over it. Romulus became VERY angry and killed his brother. Romulus went on about is life and founded his city, named it Roma, and lived as king for many years.
Tibernus, the River God, calmed the river so the twins would be safely brought to shore. They were found by a wolf and woodpecker, but were then found by Faustulus and Acca.
When the boys got older, they tried to overthrow Amulius. Amulius, suspecting who they really were, had Remus captured. Romulus freed Remus, and together, restored their grandfather to the throne.
Romulus and Remus went to found their own city, but couldn't decide which hill to build it on. They decided to consult the Gods, but got in a dispute over what Augury meant.
