Areobindus, a Goth who has become part of the political class of the Eastern Roman Empire, had taken part in the war of 422 against the Sasanids of king Bahram V, with the rank of comes foederatorum, that is, commander of the contingent of barbarians fighting as allies in the Roman army.

On that occasion, Areobindus had defeated in a duel one of the Sasanids, Ardazanes; and following his victory the peace was concluded.

In 434, Areobindus had been chosen consul by the Eastern court, along with the consul of the West, Aspar.

In the same year, he had been appointed magister militum per Orientem (perhaps praesentialis), a position he will hold until his death.

Theodosius II sends the Eastern imperial fleet under the command of Areobindus into Sicilian waters, taking the Vandals by surprise.

The expedition is not successful because its leaders waste time in Sicily.

Aerobindus, sent along with other generals against Attila in 443, had been defeated by the king of the Huns.

In 447, he receives the title of patricius.

An earthquake on January 27, 447, destroys large parts of the walls of Constantinople, including fifty-seven towers.

The population is threatened by a plague.

Theodosius orders Constantine, praetorian prefect of the East, to supervise the repairs.

He employs the city's demoi—factions in the Hippodrome—in the work and rebuilds the walls within sixty days.

Theodosius removes Aspar and Areobindus (magister militum) from their military commands in the winter of this year.
