Constantius II was Roman emperor from 337 to 361.

Flavius Valerius Constantius "Chlorus", also called Constantius I, was Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome.

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.
Flavius Claudius Constantius Gallus (326–354) was a statesman and ruler in the eastern provinces of the Roman Empire from 351 to 354, as Caesar under emperor Constantius II, his cousin. A grandson of emperor Constantius Chlorus and empress Flavia Maximiana Theodora, and a son of Julius Constantius and Galla, he belonged to the Constantinian dynasty. Born during the reign of his uncle Constantine the Great, he was among the few male members of the imperial family to survive the purge that followed Constantine's death. Under Constantius II, Gallus served as deputy emperor, based in Antioch and married to Constantius' sister Constantina. He dealt with a Jewish revolt in the years 351-352. Gallus ultimately fell out of favor with Constantius and was executed, being replaced as Caesar by his younger half-brother Julian.
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.

The Constantinian dynasty is an informal name for the ruling family of the Roman Empire from Constantius Chlorus to the death of Julian in 363. It is named after its most famous member, Constantine the Great, who became the sole ruler of the empire in 324.
