The gens Cassia was a Roman family of great antiquity. The earliest members of this gens appearing in history may have been patrician, but all those appearing in later times were plebeians. The first of the Cassii to obtain the consulship was Spurius Cassius Vecellinus, in 502 BC. He proposed the first agrarian law, for which he was charged with aspiring to make himself king, and put to death by the patrician nobility. The Cassii were amongst the most prominent families of the later Republic, and they frequently held high office, lasting well into imperial times. Among their namesakes are the Via Cassia, the road to Arretium, and the village of Cassianum Hirpinum, originally an estate belonging to one of this family in the country of the Hirpini.
The gens Junia or Iunia was one of the most celebrated families of ancient Rome. The gens may originally have been patrician, and was already prominent in the last days of the Roman monarchy. Lucius Junius Brutus was the nephew of Lucius Tarquinius Superbus, the seventh and last King of Rome, and on the expulsion of Tarquin in 509 BC, he became one of the first consuls of the Roman Republic.
The gens Aquillia or Aquilia was a plebeian family of great antiquity at ancient Rome. Two of the Aquillii are mentioned among the Roman nobles who conspired to bring back the Tarquins, and a member of the house, Gaius Aquillius Tuscus, was consul in 487 BC.
The gens Cornelia was one of the greatest patrician houses at ancient Rome. For more than seven hundred years, from the early decades of the Republic to the third century AD, the Cornelii produced more eminent statesmen and generals than any other gens. At least seventy-five consuls under the Republic were members of this family, beginning with Servius Cornelius Maluginensis in 485 BC. Together with the Aemilii, Claudii, Fabii, Manlii, and Valerii, the Cornelii were almost certainly numbered among the gentes maiores, the most important and powerful families of Rome, who for centuries dominated the Republican magistracies. All of the major branches of the Cornelian gens were patrician, but there were also plebeian Cornelii, at least some of whom were descended from freedmen.
The gens Marcia, occasionally written Martia, was one of the oldest and noblest houses at ancient Rome. They claimed descent from the second and fourth Roman Kings, and the first of the Marcii appearing in the history of the Republic would seem to have been patrician; but all of the families of the Marcii known in the later Republic were plebeian. The first to obtain the consulship was Gaius Marcius Rutilus in 357 BC, only a few years after the passage of the lex Licinia Sextia opened this office to the plebeians.
The gens Minucia was an ancient Roman family, which flourished from the earliest days of the Republic until imperial times. The gens was apparently of patrician origin, but was better known by its plebeian branches. The first of the Minucii to hold the consulship was Marcus Minucius Augurinus, elected consul in 497 BC.
The gens Porcia, rarely written Portia, was a plebeian family at Ancient Rome. Its members first appear in history during the third century BC. The first of the gens to achieve the consulship was Marcus Porcius Cato in 195 BC, and from then until imperial times, the Porcii regularly occupied the highest offices of the Roman state.
The gens Calvisia was an ancient Roman family, which first rose to prominence during the final decades of the Republic, and became influential in imperial times. The first of the gens to obtain the consulship was Gaius Calvisius Sabinus in 39 BC.
The gens Antistia, sometimes written Antestia on coins, was a plebeian family at ancient Rome. The first of the gens to achieve prominence was Sextus Antistius, tribune of the plebs in 422 BC.
Gaius Calvisius Sabinus was a consul of the Roman Republic in 39 BC under the Second Triumvirate. He and his consular colleague Lucius Marcius Censorinus had been the only two senators who tried to defend Julius Caesar when his assassins struck on 15 March 44 BC, and their consulship under the triumvirate is taken as a recognition of their loyalty. An inscription, described by Ronald Syme as "one of the most remarkable inscriptions ever set up in honour of a Roman senator," praises Calvisius for pietas, his sense of duty or devotion. As a military officer, Calvisius is notable for his long service and competence, though he was not without serious defeats.
The gens Caecilia was a plebeian family at ancient Rome. Members of this gens are mentioned in history as early as the fifth century BC, but the first of the Caecilii who obtained the consulship was Lucius Caecilius Metellus Denter, in 284 BC. The Caecilii Metelli were one of the most powerful families of the late Republic, from the decades before the First Punic War down to the time of Augustus.
The gens Memmia was a plebeian family at ancient Rome. The first member of the gens to achieve prominence was Gaius Memmius Gallus, praetor in 172 BC. From the period of the Jugurthine War to the age of Augustus they contributed numerous tribunes to the Republic.
The gens Considia was a plebeian family at ancient Rome. The Considii came to prominence in the last century of the Republic, and under the early Empire, but none of them rose any higher than the praetorship.
The gens Fonteia was a plebeian family at ancient Rome. Members of this gens are first mentioned toward the end of the third century BC; Titus Fonteius was a legate of Publius Cornelius Scipio during the Second Punic War. The first of the Fonteii to obtain the consulship was Gaius Fonteius Capito, consul suffectus in 33 BC.
The gens Juventia, occasionally written Jubentia, was an ancient plebeian family at Rome. After centuries of obscurity, the gens emerges into history with the appearance of Titus Juventius, a military tribune, in the beginning of the second century BC. The first of the Juventii to obtain the consulship was Marcus Juventius Thalna in 163 BC. But the family is renowned less for its statesmen than for its jurists, who flourished during the second century AD.
The gens Nonia was a plebeian family at ancient Rome. Its members first appear in history toward the end of the Republic. The first of the Nonii to obtain the consulship was Lucius Nonius Asprenas in 36 BC. From then until the end of the fourth century, they regularly held the highest offices of the Roman state.
The gens Naevia, occasionally written Navia, was a plebeian or patrician family at ancient Rome. Members of this gens are first mentioned at the time of the Second Punic War, but the first of the Naevii to obtain the consulship was Lucius Naevius Surdinus, in AD 30.
The gens Munatia was a plebeian family at Rome. Members of this gens are first mentioned during the second century BC, but they did not obtain any of the higher offices of the Roman state until imperial times.
The gens Opimia, also written Opeimia on coins, was a plebeian family at ancient Rome. Members of this gens are first mentioned during the time of the Samnite Wars, and they are mentioned in Roman historians from then down to the end of the Republic. The first of the Opimii to obtain the consulship was Quintus Opimius in 154 BC.
The gens Plautia, sometimes written Plotia, was a plebeian family at ancient Rome. Members of this gens first appear in history in the middle of the fourth century BC, when Gaius Plautius Proculus obtained the consulship soon after that magistracy was opened to the plebeian order by the Licinio-Sextian rogations. Little is heard of the Plautii from the period of the Samnite Wars down to the late second century BC, but from then to imperial times they regularly held the consulship and other offices of importance. In the first century AD, the emperor Claudius, whose first wife was a member of this family, granted patrician status to one branch of the Plautii.
