Licinius

Licinius I (Latin: Gaius Valerius Licinianus Licinius Augustus; c. 263–325) was a Roman emperor from 308 to 324. For most of his reign he was the colleague and rival of Constantine I, with whom he co-authored the Edict of Milan that granted official toleration to Christians in the Roman Empire. He was finally defeated at the Battle of Chrysopolis, before being executed on the orders of Constantine I.

Early reign

Born to a Dacian peasant family in Moesia Superior, Licinius accompanied his close childhood friend, the future emperor Galerius, on the Persian expedition in 298. He was trusted enough by Galerius that in 307 he was sent as an envoy to Maxentius in Italy to attempt to reach some agreement about the latter's illegitimate political position. Galerius then trusted the eastern provinces to Licinius when he went to deal with Maxentius personally after the death of Flavius Valerius Severus.

Upon his return to the east Galerius elevated Licinius to the rank of Augustus in the West on November 11, 308. He received as his immediate command the provinces of Illyricum, Thrace and Pannonia. In 310 he took command of the war against the Sarmatians, inflicting a severe defeat on them and emerging victorious. On the death of Galerius in May 311, Licinius entered into an agreement with Maximinus II (Daia) to share the eastern provinces between them. By this point, not only was Licinius the official Augustus of the west but he also possessed part of the eastern provinces as well, as the Hellespont and the Bosporus became the dividing line, with Licinius taking the European provinces and Maximinus taking the Asian.

Licinia (gens)

The gens Licinia was a celebrated plebeian family at Rome, which appears from the earliest days of the Republic until imperial times, and which eventually obtained the imperial dignity. The first of the gens to obtain the consulship was Gaius Licinius Calvus Stolo, who, as tribune of the plebs from 376 to 367 BC, prevented the election of any of the annual magistrates, until the patricians acquiesced to the passage of the lex Licinia Sextia, or Licinian Rogations. This law, named for Licinius and his colleague, Lucius Sextius, opened the consulship for the first time to the plebeians. Licinius himself was subsequently elected consul in 364 and 361 BC, and from this time, the Licinii became one of the most illustrious gentes in the Republic.

Origin of the gens

The nomen Licinius is derived from the cognomen Licinus, found in a number of Roman gentes. Licinus may have been an ancient praenomen, but few examples of its use as such are known. The name appears to be derived from the Etruscan Lecne, which frequently occurs on Etruscan sepulchral monuments. The Licinii were probably of Etruscan origin, and may have come to Rome during the time of the later kings, two of whom, Lucius Tarquinius Priscus and his son or grandson, Lucius Tarquinius Superbus, were themselves Etruscan.
