The legend goes that Rome was founded by twin brothers Romulus and Remus on April 21st in 753 BC.
Romulus and Remus were the sons of Rhea Silvia, daughter of King Numitor of Alba Longa, and Mars, the Roman god of war.
King Numitor was overthrown by his brother Amulius, who subsequently ordered for the twins to be abandoned, believing a prophecy that they would overthrow him. The infants were meant to be drowned in the Tiber River, but they survived and were discovered by a she-wolf who suckled them until they were found and reared by the shepherd Faustulus.
Once the twins learned their true identity, they attacked Alba Longa, killing Amulius and restoring Numitor in the process. Romulus and Remus decided to found a town of their own. Following a dispute, Romulus killed Remus and became ruler of what became Rome.
