Text #9643"Roman-Etruscan Wars", in .
In the 8th century BC, during the reign of Rome’s first king, Romulus, the Fidenates (an Etruscan people) decided to suppress Rome as a future threat and began to waste its territory, in opposition to which Romulus marched on Fidenae and camped a mile from it. Setting an ambush in the thickets he brought the rest of the army to the gates of Fidenae to provoke them into exiting the city. Seeing the appearance of disorder the Fidenates sallied out in pursuit and were caught in the ambush. Romulus’ troops wheeled, drove the Fidenates through their gates so closely that they were not able to close them, and took the town.
The Veientes were concerned at the situation with Fidenae both because of its proximity to Veii and their consanguinuity with the Fidenates (who were also Etruscan), and accordingly launched an incursion into Roman territory. After having done so, the Veientes returned to Veii with their booty. Romulus and the Roman army followed and met the Veientes in battle outside the walls of Veii. The Romans were victorious and the Veientes fled into the city. The Romans, not having the strength to take to city by storm, instead laid waste their lands. The Veientes sued for peace, and a one-hundred year treaty was concluded upon Veientes giving to the Romans a part of their own territory.
