 Dionysius relates that Cameria submitted to Tarquin after receiving favourable terms, indicating that the city had regained its independence since its earlier conquest.Following the expulsion of Tarquin the Proud, the seventh and last Roman King, in 509 BC, Cameria was one of the towns which rallied to the banners of Octavius Mamilius, the dictator of Tusculum, and Tarquin's son-in-law.Mamilius led a coalition of Latin cities in an attempt to restore Tarquin to the throne, in concert with the Etruscan king Lars Porsena of Clusium.
