Velletri was an ancient city of the Volsci tribe. Legendarily it came into conflict with the Romans during the reign of Ancus Marcius, the fourth king of Rome; then again in the fifth and fourth centuries BCE, during the early Roman Republic. Velletri was also the home of the Octavii, the paternal family of the first Roman Emperor Augustus.
