Theodosius I, also called Theodosius the Great, was a Roman emperor from 379 to 395. He won two civil wars, and was instrumental in establishing the Nicene Creed as the orthodox doctrine for Nicene Christianity. Theodosius was the last emperor to rule the entire Roman Empire before its administration was permanently split between the Western Roman Empire and the Eastern Roman Empire. He successfully ended the Gothic War (376–382) with terms advantageous to the empire, with the Goths remaining in Roman territory but as subject allies.

Magnus Maximus was Roman emperor in the West 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 half-brother, then was sidelined by a usurper, and finally became sole ruler after 388, albeit with limited de facto powers.
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.
The 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.
Arbogast or Arbogastes was a Roman army officer of Frankish origin. He won distinction in the service of the emperor Gratian, and was subsequently entrusted by Theodosius I with the guardianship of the underage Valentinian II. The death of Valentinian in mysterious circumstances, and the rise of the controversial Eugenius, led to a civil war in which Arbogast perished.
The Battle of Poetovio was fought in 388 between the forces of Western Roman Emperor Magnus Maximus and the Eastern Roman Emperor Theodosius I. Magnus Maximus's army was defeated and Maximus was later captured and executed at Aquileia.

Flavius Bauto was a Romanised Frank who served as a magister militum of the Roman Empire and was a powerful figure in the court of emperor Valentinian II.
Flavius Merobaudes was a Roman army officer of Frankish origin. He was appointed magister peditum around 375, and consul twice in 377 and 383. Ancient sources record that he was put to death that year for his support of the imperial usurper Magnus Maximus, but an inscription records that he became consul a third time in 388.
