On this day...

21st April is the datetraditionally taken as the day when Rome was founded. Roman historians dated the city's foundation variously from 758 to 728 BC.
Ancestors of Aeneas and fathered by Mars or Hercules, Romulus and Remus decided to found a new city after regaining their regal birthrights. However, the brothers had differing opinions on where to situate the city (Romulus wished to build on the Palatine Hill, but Remus wanted to build on the Aventine Hill). They agreed to determine the site through augury, but, again, they disputed the results. In the consequent clashes, Remus was killed.
