Aulus Allienus was the name of two ancient Romans who lived roughly around the 1st century BC, and who may have been the same person:
The gens Gabinia was a plebeian family at ancient Rome. Members of this gens first appear in the second century BC. The nomen derives from the city of Gabii, east of Rome.
The gens Sempronia was one of the most ancient and noble houses of ancient Rome. Although the oldest branch of this gens was patrician, with Aulus Sempronius Atratinus obtaining the consulship in 497 BC, the thirteenth year of the Republic, but from the time of the Samnite Wars onward, most if not all of the Sempronii appearing in history were plebeians. Although the Sempronii were illustrious under the Republic, few of them attained any importance or notice in imperial times.
The gens Caesia was a minor plebeian family at ancient Rome during the late Republic, and through to imperial times. The first member of this gens to achieve prominence was Marcus Caesius, praetor in 75 BC. Under the Empire, the Caesii were distinguished for their literary achievements.
Aulus Postumius Albinus was a statesman of the Roman Republic, notably consul in 151 BC. He was also a historian and wrote the Annals in Greek.
The gens Lollia was a plebeian family at Rome. Members of the gens do not appear at Rome until the last century of the Republic. The first of the family to obtain the consulship was Marcus Lollius, in 21 BC.
The gens Alliena or Aliena was a minor plebeian family of the Roman Republic. The first member of the gens to achieve prominence was Lucius Alienus, plebeian aedile in 454 BC. However, the family then slipped into obscurity for several centuries, emerging once more in the first century BC.
The gens Titia was a plebeian family at ancient Rome. The gens is rarely mentioned in the Republican period, and did not rise out of obscurity till a very late time. None of its members obtained the consulship under the Republic, and the first person of the name who held this office was Marcus Titius in BC 31.
The gens Hostilia was an ancient family at Rome, which traced its origin to the time of Romulus. The most famous member of the gens was Tullus Hostilius, the third King of Rome; however, all of the Hostilii known from the time of the Republic were plebeians. Several of the Hostilii were distinguished during the Punic Wars. The first of the family to obtain the consulship was Aulus Hostilius Mancinus in 170 BC.
The gens Maria was a plebeian family of Rome. Its most celebrated member was Gaius Marius, one of the greatest generals of antiquity, and seven times consul.
The gens Caninia was a plebeian family at ancient Rome during the later Republic. The first member of the gens who obtained any of the curule offices was Gaius Caninius Rebilus, praetor in 171 BC; but the first Caninius who was consul was his namesake, Gaius Caninius Rebilus, in 45 BC.
The gens Septimia was a minor plebeian family at ancient Rome. The gens first appears in history towards the close of the Republic, and they did not achieve much importance until the latter half of the second century, when Lucius Septimius Severus obtained the imperial dignity.
The gens Cluvia was a plebeian family at ancient Rome, known from the later Republic, and early imperial times. The first member of the gens to achieve prominence was Gaius Cluvius Saxula, praetor in 175 and 173 BC.
The gens Erucia was a plebeian family at Rome. Members of this gens are first mentioned early in the first century BC; the name has been claimed as Etruscan. However, in the second century of the Empire, the Erucii attained considerable distinction.
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 Oppia was an ancient Roman family, known from the first century of the Republic down to imperial times. The gens may originally have been patrician, as they supplied priestesses to the College of Vestals at a very early date, but all of the Oppii known to history were plebeians. None of them obtained the consulship until imperial times.
The gens Pacuvia was a minor plebeian family at ancient Rome. Members of this gens are first mentioned during the second century BC, and from then down to the first century of the Empire Pacuvii are occasionally encountered in the historians. The first of the Pacuvii to achieve prominence at Rome, and certainly the most illustrious of the family, was the tragic poet Marcus Pacuvius.
The gens Pupia was a plebeian family at ancient Rome. Members of this gens are mentioned as early as 409 BC, when Publius Pupius was one of the first plebeian quaestors, but over the course of centuries they achieved little of significance, and rarely held any of the higher offices of the Roman state.
The gens Satria was a minor plebeian family at ancient Rome. Members of this gens are mentioned in the first century BC, and under the early Empire, but none of them rose higher than the rank of praetor. Otherwise the Satrii are known largely from inscriptions.
The gens Silia was a plebeian family at ancient Rome. Members of this gens are mentioned as early as the fifth century BC, but first to hold the consulship was Publius Silius Nerva, in the time of Augustus. The Silii remained prominent until the time of the Severan dynasty, in the early third century.
The gens Sittia was a minor plebeian family at ancient Rome. The most illustrious member of this gens was Publius Sittius, an adventurer who met with great success during the African War, after allying himself with Caesar.
