Flavius Romulus (died 28 September 351 AD) was a Roman politician, appointed to the high position of consul in 343. The historian Benet Salway tentatively identified him with Romulus, the senior army officer who fought and died for the usurper Magnentius at the Battle of Mursa in 351.
Salway suggested Romulus was a leading member of the military establishment of Emperor Constans (r. 337–350), and thus his (and not his brother's) appointee for the consulate. Romulus would then have been among the high military officials who overthrew Constans and proclaimed Magnentius as emperor in January 350. He commanded Magnentius's forces (apparently with the rank of magister equitum, 'master of cavalry') in the Battle of Mursa against Constantius, the brother and co-emperor of Constans. Zosimus related that Romulus was wounded by a dart, but fought on and did not die until he killed the enemy who threw it.
The editors of the Prosopography of the Later Roman Empire suggest Flavius Pisidius Romulus, urban prefect of Rome in the early 5th century, was his descendant.
Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.
Flavius Julius Constans, sometimes called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.
Constantine II was Roman emperor from 337 to 340. Son of Constantine the Great and co-emperor alongside his brothers, his attempt to exert his perceived rights of primogeniture led to his death in a failed invasion of Italy in 340.
The 350s decade ran from January 1, 350, to December 31, 359.
Year 351 (CCCLI) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magnentius and Gaiso. The denomination 351 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Valentinian I, sometimes called Valentinian the Great, was Roman emperor from 364 to 375. He ruled the Western half of the empire, while his brother Valens ruled the East. During his reign, he fought successfully against the Alamanni, Quadi, and Sarmatians, strengthening the border fortifications and conducting campaigns across the Rhine and Danube. His general Theodosius defeated a revolt in Africa and the Great Conspiracy, a coordinated assault on Roman Britain by Picts, Scoti, and Saxons. Valentinian founded the Valentinianic dynasty, with his sons Gratian and Valentinian II succeeding him in the western half of the empire.
Magnus Magnentius was a Roman general and usurper against Constantius II from 350 to 353. Of Germanic descent, Magnentius served with distinction in Gaul under the Western emperor Constans. On 18 January 350 Magnentius was acclaimed Augustus. Quickly killing the unpopular Constans, Magnentius gained control over most of the Western Empire. The Eastern emperor Constantius II, the brother of Constans, refused to acknowledge Magnentius' legitimacy and led a successful campaign against Magnentius in the Roman civil war of 350–353. Ultimately, Magnentius' forces were scattered after the Battle of Mons Seleucus, and he committed suicide on 11 August 353.
Vetranio was briefly Western Roman emperor in 350, allying with the Eastern emperor Constantius II in his war against Magnentius.
Nepotianus, sometimes known in English as Nepotian, was a member of the Constantinian dynasty who reigned as a short-lived usurper of the Roman Empire. He ruled the city of Rome for twenty-eight days, before being killed by his rival usurper Magnentius' general Marcellinus.
The gens Flavia was a plebeian family at ancient Rome. Its members are first mentioned during the last three centuries of the Republic. The first of the Flavii to achieve prominence was Marcus Flavius, tribune of the plebs in 327 and 323 BC; however, no Flavius attained the consulship until Gaius Flavius Fimbria in 104 BC. The gens became illustrious during the first century AD, when the family of the Flavii Sabini claimed the imperial dignity.
Justina was a Roman empress. She was initially the wife of the rebel emperor Magnentius and was then married to Valentinian I, with whom she had four children, including the emperor Valentinian II and the empress Galla.
The Battle of Mursa was fought on 28 September 351 between the eastern Roman armies led by the Emperor Constantius II and the western forces supporting the usurper Magnentius. It took place at Mursa, near the Via Militaris in the province of Pannonia. The battle, one of the bloodiest in Roman history, was a pyrrhic victory for Constantius.

Constantinople, formally named Nova Roma, was founded in the city of Byzantium, which is the origin of the historiographical name for the Eastern Empire, which self-identified simply as the "Roman Empire".
