Flavius Dalmatius (died 337), also known as Dalmatius the Censor, was a censor (333), and a member of the Constantinian dynasty, which ruled over the Roman Empire at the beginning of the 4th century.
Dalmatius was the son of Constantius Chlorus and Flavia Maximiana Theodora, and thus half-brother of the Emperor Constantine I.
Flavius Hannibalianus (also Hanniballianus; died September 337) was a member of the Constantinian dynasty, which ruled over the Roman Empire in the 4th century.
Hannibalianus was the son of Flavius Dalmatius, and thus nephew of Constantine the Great. Hannibalianus and his brother Dalmatius were educated at Tolosa by rhetor Exuperius (who is probably not to be identified with St. Exuperius).
Constantius II (Latin: Flavius Julius Constantius; Ancient Greek: Κωνστάντιος, romanized: Kōnstántios; 7 August 317 – 3 November 361) 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.
Constantius was a son of Constantine the Great, who elevated him to the imperial rank of Caesar on 8 November 324 and after whose death Constantius became Augustus together with his brothers, Constantine II and Constans on 9 September 337. He promptly oversaw the massacre of his father-in-law, an uncle, and several cousins, consolidating his hold on power. The brothers divided the empire among themselves, with Constantius receiving Greece, Thrace, the Asian provinces, and Egypt in the east. For the following decade a costly and inconclusive war against Persia took most of Constantius's time and attention. In the meantime, his brothers Constantine and Constans warred over the western provinces of the empire, leaving the former dead in 340 and the latter as sole ruler of the west. The two remaining brothers maintained an uneasy peace with each other until, in 350, Constans was overthrown and assassinated by the usurper Magnentius.
Flavius Dalmatius (died September 337), often spelled Delmatius on contemporary coins, was a Caesar of the Roman Empire from 335 to 337, and member of the Constantinian dynasty.
Dalmatius was the nephew of Constantine the Great. His father, also named Flavius Dalmatius, was the half-brother of Constantine and served as censor. Dalmatius and his brother Hannibalianus were educated at Tolosa (Toulouse) by rhetor Exuperius.
