Publilia gens

The gens Publilia (Pūblilia), sometimes written Poblilia, was a plebeian family at ancient Rome. Members of this gens are first mentioned in the early decades of the Republic. The lex Publilia passed by Volero Publilius, tribune of the plebs in 471 BC, was an important milestone in the struggle between the patrician and plebeian orders. Although the Publilii appear throughout the history of the Republic, the family faded into obscurity around the time of the Samnite Wars, and never again achieved positions of prominence in the Roman state.

Origin
The nomen Publilius is a patronymic surname based on the Latin praenomen Publius, with which it is frequently confused.

Praenomina
The praenomina used by the Publilii included Volero, Lucius, Quintus, Gaius, and Titus. All were very common throughout Roman history, except for Volero; the Publilii were the only important family to make use of that name.

Branches and cognomina
The only distinct family of the Publilii under the Republic bore the cognomen Philo, from the Greek "to love". One member of this family bore the additional surname Volscus, a Volscian, presumably for some deed involving the Volsci.

Publilii Philones

 * Volero Publilius, a distinguished veteran, was ill-treated by the consuls of 473 BC, and after his plight became known he was elected one of the tribunes of the plebs. Two years later, he passed the lex Publilia, transferring the election of the tribunes from the comitia centuriata to the comitia tributa, and raising the number of tribunes to be elected each year from two to five.
 * Lucius Publilius Vol. f. (Philo), son of the celebrated tribune of the plebs Volero Publilius, and father of the consular tribunes Lucius and Volero.

 * Quintus Publilius Q. f. Philo, father of Quintus Publilius Philo, four times consul.
 * Quintus Publilius Q. f. Q. n. Philo, consul in 339 BC, defeated the Latins, and received a triumph. The same year, he was nominated dictator, and secured the passage of the leges Publiliae, further increasing the political equality of the plebeians.  He was the first plebeian praetor in 335, magister equitum in 335, and censor in 332.  Consul a second time in 327, he laid siege to Palaepolis, which he captured as the first proconsul in 326, triumphing for the second time.  In his third consulship, BC 320, he defeated a Samnite army to rescue the army of his colleague.  He was consul a fourth time in 315.
