The Roman Kingdom began as a small settlement in Latium and is
recognizable in the Bronze age (2000-1000BC), a distinct culture
begins to be recognizable in the Proto-Villanovan period
(1200-900BC), said to be marked by the arrival of the Etruscans
North of Rome. The Roman culture develops throughout the
Iron/Villanovan age (1000-580BC) which is broken down into 4
periods (Latial I, II, III, IV). There is argument about when
exactly the Roman Kingdom ends/Republic begins, but it is either
507BC or 509BC and is marked by the expulsion of Tarquinius Priscus
(the last king).
