Manilia gens

The gens Manilia was a plebeian family at ancient Rome. Members of this gens are frequently confused with the Manlii, Mallii, and Mamilii. Several of the Manilii were distinguished in the service of the Republic, with Manius Manilius obtaining the consulship in 149 BC; but the family itself remained small and relatively unimportant.

Origin
The nomen Manilius seems to be derived from the praenomen Manius, and so probably shares a common root with the nomen of the Manlii. This being the case, the Manilii were almost certainly of Latin origin.

Branches and cognomina
The Manilii were never divided into distinct families, and the only surname found under the Republic is Mancinus, although this probably belonged to one of the Manlii, who has been erroneously named as a Manilius in some manuscripts. A few cognomina are found in Imperial times.

Members

 * Sextus Manilius, one of the leaders of the soldiers who led the second secession of the plebs in 449 BC, together with Marcus Oppius, after the death of Verginia. Dionysius gives his name as Manlius.
 * Publius Manilius, grandfather of the consul and jurist Manius Manilius.
 * Manilius, praetor in 182 BC, was assigned the province of Hispania Citerior, where he restored discipline among the soldiers. He was expelled from the senate by Cato the Censor, but subsequently restored.  He is probably identical with Publius Manlius.
 * Publius Manilius, one of the legates sent to assist the propraetor Lucius Anicius Gallus settle the affairs of Illyricum in 167 BC.
 * Manius Manilius P. f. P. n., consul in 149 BC, during the Third Punic War. He and his colleague, Lucius Marcius Censorinus, led the attack on Carthage, burning the Carthaginian fleet within sight of the city. But it was as a jurist that Manilius earned his reputation; Sextus Pomponius calls him one of the founders of the civil law, and Cicero describes him as a skilled orator.
 * Manilius, or perhaps Manlius, praetor in 137 BC, was sent to quell a slave revolt in Sicily, but was defeated by Eunus, the leader of the rebellion.
 * Publius Manilius P. f. (M'. n.), consul in 120 BC.
 * Manilius Mancinus, tribune of the plebs in 108 BC, proposed the law granting Gaius Marius, the consul-elect, the province of Numidia and the command against Jugurtha. He may have been a Manlius rather than a Manilius; Broughton gives his name as Titus Manlius Mancinus.
 * Lucius Manilius, praetor in 79 BC, the following year received proconsular authority over the province of Gallia Narbonensis. He crossed into Hispania to assist the proconsul Metellus in the war with Sertorius, with three legions and fifteen hundred cavalry.  He was decisively beaten by Lucius Hirtuleius, losing his entire army, and escaping into the town of Ilerda.
 * Gaius Manilius, tribune of the plebs in 66 BC, who passed the Lex Manilia granting Gnaeus Pompeius special powers to fight Mithridates VI. Manilius' enemies brought him to trial on an uncertain charge; perhaps extortion, or disturbing another trial.  He was defended by Cicero, but to no avail, and was condemned.
 * Quintus Manilius, tribune of the plebs in 52 BC.
 * Marcus Manilius, the author of an astrological poem entitled Astronomica.
 * Manilius, the author of an epigram quoted by Varro. He may be identical with the author of Astronomica.
 * Quintus Manlius Ancharius Tarquitius Saturninus, consul in 62 and later proconsul of Africa
 * Publius Manilius Vopiscus Vicinillianus, consul in AD 114.
