Theodosius I, also called Theodosius the Great, was Roman emperor from 379 to 395. During his reign, he succeeded in a crucial war against the Goths, as well as in two civil wars, and was instrumental in establishing the creed of Nicaea as the orthodox doctrine for Christianity. Theodosius was the last emperor to rule the entire Roman Empire before its administration was permanently split between the West and East.
The 380s decade ran from January 1, 380, to December 31, 389.
Magnus Maximus was Roman emperor of the Western Roman Empire from 383 to 388. He usurped the throne from emperor Gratian.
Gratian was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.
Valentinian II was a Roman emperor in the western part of the Roman empire between AD 375 and 392. He was at first junior co-ruler of his brother, was then sidelined by a usurper, and only after 388 sole ruler, albeit with limited de facto powers.
Aetius was a Roman general and statesman of the closing period of the Western Roman Empire. He was a military commander and the most influential man in the Empire for two decades (433–454). He managed policy in regard to the attacks of barbarian federates settled throughout the West. Notably, he mustered a large Roman and allied (foederati) army in the Battle of the Catalaunian Plains, ending a devastating invasion of Gaul by Attila in 451, though the Hun and his subjugated allies still managed to invade Italy the following year, an incursion best remembered for the ruthless Sack of Aquileia and the intercession of Pope Leo I.
Magister militum was a top-level military command used in the later Roman Empire, dating from the reign of Constantine the Great. The term referred to the senior military officer of the empire. In Greek sources, the term is translated either as strategos or as stratelates.
Eugenius was a usurper in the Western Roman Empire (392–394) against Emperor Theodosius I. While Christian himself, Eugenius capitalized on the discontent in the West caused by Theodosius' religious policies targeting pagans. He renovated the pagan Temple of Venus and Roma and restored the Altar of Victory after continued petitions from the Roman Senate. Eugenius replaced Theodosius' administrators with men loyal to him including pagans. This revived the pagan cause. His army fought the army of Theodosius at the Battle of the Frigidus, where he was captured and executed.
Petronius Maximus was Roman emperor of the West for two and a half months in 455. A wealthy senator and a prominent aristocrat, he was instrumental in the murders of the Western Roman magister militum, Aëtius, and the Western Roman emperor, Valentinian III.
Victor was a Western Roman emperor from either 383/384 or 387 to August 388. He was the son of the magister militum Magnus Maximus, who later became a usurper of the Western Roman Empire, in opposition to Gratian. Maximus rose up in 383, and was recognized as the legitimate emperor in the west by Theodosius I. Victor was elevated to augustus of the Western Roman Empire in either 383/384 or mid-387, making him co-emperor with his father. Maximus invaded Italy in 387, to depose Valentinian II, the brother and successor of the late Gratian. Because of Maximus' invasion, Theodosius invaded the Western Empire in 388. Theodosius defeated Maximus in two battles in Pannonia, before crushing his army at Aquilea, and capturing Maximus. Maximus was executed on 28 August 388. His death was followed quickly by that of Victor, who was executed in Trier by the Frankish general Arbogast.
The Theodosian dynasty was a Roman imperial family that produced five Roman emperors during Late Antiquity, reigning over the Roman Empire from 379 to 457. The dynasty's patriarch was Theodosius the Elder, whose son Theodosius the Great was made Roman emperor in 379. Theodosius's two sons both became emperors, while his daughter married Constantius III, producing a daughter that became an empress and a son also became emperor. The dynasty of Theodosius married into, and reigned concurrently with, the ruling Valentinianic dynasty, and was succeeded by the Leonid dynasty with the accession of Leo the Great.
Licinia Eudoxia was a Roman Empress, daughter of Eastern Roman Emperor Theodosius II. Her husbands included the Western Roman Emperors Valentinian III and Petronius Maximus.
The Battle of the Frigidus, also called the Battle of the Frigid River, was fought on 5 and 6 September 394 between the armies of the Roman emperor Theodosius the Great and the rebel augustus Eugenius, in the eastern border of Roman Italy. Theodosius won the battle and defeated the usurpation of Eugenius and Arbogast, restoring unity to the Roman Empire. The battlefield, in the Claustra Alpium Iuliarum near the Julian Alps through which Theodosius's army had passed, was probably in the Vipava Valley – with the Frigidus River being the modern Vipava – or possibly in the valley of the Isonzo.
The Valentinianic or Valentinian dynasty was a ruling house of five generations of dynasts, including five Roman emperors during Late Antiquity, lasting nearly a hundred years from the mid fourth to the mid fifth century. They succeeded the Constantinian dynasty and reigned over the Roman Empire from 364 to 392 and from 425 to 455, with an interregnum (392–423), during which the Theodosian dynasty ruled and eventually succeeded them. The Theodosians, who intermarried into the Valentinian house, ruled concurrently in the east after 379.
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.
Arbogastes or Arbogast was a Roman army officer of Frankish origin.
Galla was a Roman empress as the second wife of Theodosius I. She was the daughter of Valentinian I and his second wife Justina.
In historiography, the Later Roman Empire traditionally spans the period from 284 to 641 in the history of the Roman Empire.
The gens Rufia, occasionally spelled Ruffia, was a minor plebeian family at ancient Rome. Members of this gens are not mentioned in history until imperial times, and they achieved little prominence until the late third century, from which time the family rose in importance, gaining the consulship on a number of occasions from the time of Constantine the Great to that of Justinian, and frequently holding the post of praefectus urbi.
The history of the Later Roman Empire covers the history of the Roman Empire from the beginning of the rule of Diocletian in 284 AD and the establishment of the Tetrarchy in 293 AD by Diocletian to the death of Heraclius in 641 AD.
