Lanuvium

Lanuvium (more frequently Lanivium in Imperial Roman times, later Civita Lavinia, modern Lanuvio) is an ancient city of Latium (Latin: Lānŭuĭum or Lānĭuĭum), some 32 kilometres (20 mi) southeast of Rome, a little southwest of the Via Appia.

Situated on an isolated hill projecting south from the main mass of the Alban Hills, Lanuvium commanded an extensive view over the low country between it and the sea. According to the legend, it was founded by Diomedes, or by one Lanoios, an exile from Troy. The first documented traces of the settlement date from the 9th century BC and by the 6th century BC it was part of the Latin League.

The city warred against Rome at the battles of Aricia (504 BC) and Lake Regillus (496 BC), as well as in 383 and 341 BC, mostly with negative outcomes. Rome conquered Lanuvium in 338 BC; at first its denizens did not enjoy the right of Roman citizenship, but acquired it later. In imperial times the city's chief magistrate and municipal council kept the titles of dictator and senatus respectively.
