Arbogast (general)
Flavius Arbogastes (died September 8, 394), or Arbogast was a Frankish general in the Roman Empire. It has been stated by some ancient historians that he was the son of Flavius Bauto, Valentinian II's former magister militum and protector before Arbogast, but modern scholars largely discount this claim.
Early career
Flavius Arbogastes, or simply Arbogast, was the nephew of the great Frankish General Flavius Richomeres and resided within the Frankish domain as a native of Galatia Minor until he was expelled in the later 370s CE.
His Germanic name, *Arbogastiz, is also otherwise attested; it is derived from the elements arbo- "heir; inheritance" and gastiz "guest, spirit".
It was at this point when Arbogast joined the Roman imperial military service under the command of the emperor Gratian, son of Valentinian I and elder brother to Valentinian II, in the Western Roman Empire. Shortly after his induction into the Roman military, Arbogast made a name for himself as being an extremely efficient and loyal field-commander. So much so, in fact, that in 380 CE Gratian sent Arbogast along with his magister militum Bauto to aid Theodosius I against the Goths and their leader Fritigern after they had pillaged and plundered areas of Macedonia and Thessaly that year and the year before. The Western armies, commanded by Bauto and Arbogast, and those from Theodosius I in the East, successfully pushed Fritigern out of Macedonia and Thessaly towards Thrace in lower Moesia where their raids had begun, and ultimately established a peace treaty with the Visigoths in 382 CE.
