There are several dates but this is the traditional date! On April 21, 753 B.C. orphan twin brothers, Romulus and Remus, were nursed by a she-wolf at the base of Palatine Hill. They were later raised by shepherds, and became great warriors. Together they founded a town on the spot that they were saved from. Romulus killed his twin Remus over a small argument. Making him the solo ruler of the town and naming it after himself! Rome!
