Sextus Julius Iullus

Sextus Julius Iullus was a consular tribune of the Roman Republic in 424 BC.

Julius belonged to the patricianJulia gens and the branch known as the Julii Iulli, one of the early republics most influential families having produced five consuls prior to Sextus Julius. He is the first known Sextus among the Julii, a praenomen otherwise associated with a younger branch, the Julii Caesares, who appeared by the end of the 3rd century BC. As no filiations have survived it remains unclear of Julius connection to the other known Julii Iulli of the period, but there remains a possibility that Lucius Julius Iullus, consular tribune in 388 and 379 BC, was his son.
