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, also 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. The son of the emperor Constantine I, he was proclaimed caesar by his father shortly after his birth. He was associated with military victories over the Sarmatians, Alamanni and Goths during his career, for which he was granted a number of victory titles. He held the consulship four times – in 320, 321, 324, and 329.

Year 335 (CCCXXXV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantius and Albinus. The denomination 335 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.
Flavius Valerius Constantius, also called Constantius I, was a 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. The nickname "Chlorus" was first popularized by Byzantine-era historians and not used during the emperor's lifetime.
Magnus Magnentius was a Roman general and usurper against Constantius II. Of Germanic descent, Magnentius served with distinction in Gaul under the 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. Ultimately, Magnentius' forces were scattered after the Battle of Mons Seleucus, and he died by suicide on 10 August 353.
Flavius Claudius Constantius Gallus 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.

Flavia Valeria Constantina, later known as Saint Constance, was the eldest daughter of Roman emperor Constantine the Great and his second wife Fausta, daughter of Emperor Maximian. Constantina may have received the title of Augusta from her father, and is venerated as a saint, having developed a medieval legend wildly at variance with what is known of her actual character.
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. The dynasty is also called Neo-Flavian because every Constantinian emperor bore the name Flavius, similarly to the rulers of the first Flavian dynasty in the 1st century.

It does not cover the imperial usurpers of the period, including Magnentius, Vetranio, Claudius Silvanus, and Poemenius. The chronology is principally derived from Timothy Barnes' Athanasius and Constantius. Substantial additions and further sources are based on recent research that seeks to go beyond Barnes' own chronology and slightly modifying his at a few places.
