Servius Tullius

Servius Tullius was the son-in-law of Lucius Tarquinius Priscus, and was the sixth king of Rome (578-534 BC). It's not certain whether Servius was a Latin or an Etruscan. If he was an Etruscan, then his name was originally Mastarna.

Servius was responsible for the construction of Rome's defensive walls. Servius also reorganised the administrative and tactical units of Roman army according to the property classes of the Roman people. The army was divided into centuries; each century would contain about a hundred men.

Lastly, Servius established a temple for the cult of Diana on the Aventine Hill.

Servius ruled for 44 years before he was assassinated by his own daughter Tullia and his son-in-law, Lucius Tarquinius Superbus.
