Tullus Hostilius
As with those of all the early kings of Rome, the events ascribed to the reign of Tullus Hostilius are treated with scepticism by modern historians. Part of this is due to obvious flaws in the literary tradition describing the kings: much like the confusion the Ancients exhibited in attributing identical accomplishments to both Tarquinius Priscus and Tarquinius Superbus, the accomplishments of Tullus Hostilius are thought by many scholars to be rhetorical doublet of those of Romulus. Both are brought up among shepherds, carry on war against Fidenae and Veii, double the number of citizens, and organize the army. Additionally, Tullus Hostilius' warlike and ferocious character seems to be little more than a contrasting stereotype to that of the peaceable, devout Numa Pompilius; the first Roman annalists may merely have imputed aggressive qualities to Hostilius by naively parsing his gentile name ("Hostilius" meaning "hostile" in Latin).
