Every Etruscan stronghold was built on an elevation, and Veii was no exception. Its "arx", or citadel, was placed on a bluff delineated by cliffs within the angle of confluence of the two streams, nearly separated from the main ridge by a gully, through which ran a road in the Roman period. An archaeological site, Piazza d'Armi ("military square"), marks the location today. The earliest evidence of occupation by demographic analysis, including that of the cemeteries, dates from the 10th century BC in the Late Bronze Age. Small settlements were scattered over a wider area than the plateau and the population of the plateau at Veii is estimated to have been stable at about 1000. In the 9th century BC, the Early Iron Age (Villanovan culture), the finds are localised to the plateau but appear to be associated with independent settlements, each with its own cemetery. Occupation gradually intensified in the 8th (remainder of Villanovan) and 7th (Orientalising Period) centuries BC, by conurbation of the settlements as the site assumed an urban appearance with city blocks in a grid pattern arranged around a central square containing a water cistern. That evidence suggests that the city of Veii was shaped into its classical form in the 7th century BC by a population, presumably Etruscan, first settling there in the 10th century BC. The population of the early Veii practised both inhumation and cremation within the same family. The proportion was 50% in the 9th century BC, after a predomination of cremation (90%) earlier. In the 8th century, inhumation rose to 70%, which may be attributable to an influence from Latium, where inhumation prevailed in the 9th century BC. During the 9th and 8th centuries BC, the population density and grave goods were on the increase: more and wealthier people and also more of a disparity in wealth: the rise of a richer class. In the 8th century BC, both the potter's wheel and writing were introduced from Greece. During the entire period, the settlements translocated around the plateau; however, a settlement (Casale del Fosso) maintained a cemetery to the north of the plateau continuously from the late 9th century BC to the early 6th century BC. The documented history of Veii, like that of all Italian cities in their early centuries, is sparse and unreliable. According to Livy (writing 700 years later) the Fidenates and the Veientes were defeated in a war with Rome during the reign of Rome's mythical first king, Romulus, in the 8th century BC.
