Constantius Gallus added inhabitants of Batavia to his legions, " of whose discipline we still make use.

In 351, as a consequence of the difficulty of managing the entire empire alone, Constantius elevated his cousin Constantius Gallus, the eldest surviving son of Constantius ' half-uncle, Julius Constantius, to the subordinate rank of Caesar, but had him executed three years later after receiving scathing reports of his cousin's violent and corrupt nature.

Shortly after in 355, Constantius promoted Gallus ' younger half-brother and Constantius ' last surviving cousin, Julian to the rank of Caesar.

The massacre left Constantius, his older brother Constantine II, his younger brother Constans, and three cousins Gallus, Julian and Nepotianus as the only surviving male relatives of Constantine the Great.

However, feeling that the east still required some sort of imperial presence, he elevated his cousin Constantius Gallus to Caesar of the eastern provinces.

In the meantime, Constantius had been receiving some disturbing reports regarding the actions of his cousin Gallus.

Constantius Gallus was a paternal cousin of Constantius.

Constantius then requested the presence of Gallus and Constantina.

However, after some convincing by one of Constantius ’ agents, Gallus continued his journey west, passing through Constantinople and Thrace to Poetovio ( Ptuj ) in Pannonia.

In Poetovio, Gallus was arrested by the soldiers of Constantius under the command of Barbatio.

At first, this so greatly angered Constantius that he immediately ordered Gallus ' execution.

Unfortunately for Gallus, this order was delayed by Eusebius, one of Constantius ‘ eunuchs, and as a result Gallus was executed.

Constantius II ordered the murders of many descendants from the second marriage of Constantius Chlorus and Theodora, leaving only Constantius and his brothers Constantine II and Constans I, and their cousins, Julian and Gallus ( Julian's half-brother ), as the surviving males related to Emperor Constantine.

In need of support, in 351 he made Julian's half-brother, Gallus, Caesar of the East, while Constantius II himself turned his attention westward to Magnentius, whom he defeated decisively that year.

Constantius, after his experience with Gallus, intended his representative to be more a figurehead than an active participant in events, so he packed Julian off to Gaul with a small retinue and Constantius ' prefects in Gaul would keep him in check.

* 351 – Constantius II elevates his cousin Gallus to Caesar, and puts him in charge of the Eastern part of the Roman Empire.

* Constantius II sends his official Paulus Catena to Britain to hunt down the opponents of Magnentius.

Constantius accept the new emperor and sends him money to raise an army.

* Constantine I sends his half-brother Julius Constantius to Licinius at Sirmium ( Pannonia ), with the proposal to accept Bassianus as Caesar and his power over Italy.

Before Constantius arrived, the Persian general Narses, who was possibly the king's brother, overran Mesopotamia and captured Amida.

Before facing Magnentius, Constantius first came to terms with Vetranio, a loyal general in Illyricum who had recently been acclaimed emperor by his soldiers.

Constantius subsequently sent Vetranio the imperial diadem and acknowledged the general ‘ s new position as Augustus.

The time when Cyril was Bishop of Jerusalem was one of general tolerance, however, as set forth by the ecumenist Emperor Constantius who was preoccupied with unity.

* Flavius Constantius, Roman general and politician, is promoted to the rank of magister militum.

* January 1 – Emperor Honorius forces his half-sister Galla Placidia into marriage to Constantius, his general ( magister militum ).

* Constantius III, Roman general ( magister militum ), begins a military campaign against the Visigoths in Gaul.

* Constantius, Roman general ( magister militum ), drives the Visigoths out of Gaul.

The able general having been disposed of, Constantius besieged the city for three months until the general of Constantine, Edobichus, who had been sent across the border to find allies, did return with a large army of Franks and Alamanni.

Honorius's general Constantius ( who would later become Emperor Constantius III ), poisoned official relations with Ataulf and gained permission to blockade the Mediterranean ports of Gaul.

In 296 the general Constantius Chlorus invaded Britain to reclaim Britain for Rome.

Despite Magnentius ' efforts to gain Vetranio to his cause, the old general reached Constantius with his army, and resigned the crown.

Ammianus Marcellinus, a noted Roman historian and general who served in the army of Constantius II in Gaul and Persia and fought against the Sassanid army under Julian the Apostate, described the sight of a contingent of massed Persian cataphracts in the 4th century:

So violent did the tumult become that Constantius sent his general Hermogenes to eject Paul for a second time.

A second visit in around 446 – 7 by Germanus, a former Roman general who had become Bishop of Auxerre, recorded in Constantius ' Vita, could have reflected Aetius ' response to the message.

The Constantinian dynasty properly began with Constantius " Chlorus " ( caesar, 293, augustus, 305 ), an experienced Illyrian soldier and general ; the Constantiniani were originally another family of " Barracks Emperors ".

Basil persuaded Constantius to summon a general council, Ancyra being proposed, then Nicomedia ( both in Asia Minor ), but as the latter city was destroyed by an earthquake, Basil was again at Sirmium in 359 where the Arianizers had meanwhile regained their footing ; with Germinius of Sirmium, George of Alexandria, Ursacius and Valens, and bishop ( later saint ) Marcus of Arethusa, he held a conference which lasted until night.

He entered the army at an early age, when Constantius II was emperor of the East, and was sent to serve under Ursicinus, governor of Nisibis in Mesopotamia, and magister militum.

Constantius had made him magister militum in 353, with the purpose of blocking the German threats, a feat that Silvanus achieved by bribing the German tribes with the money he had collected.

Constantius accepted Julian's report of events and Marcellus was replaced as magister equitum by Severus.

Constantius was born in Naissus ( modern-day Niš, Serbia ) and was probably a career soldier, who reached the rank of magister militum under Honorius.

So in 411 Constantius, the magister militium ( master of military ) of the western emperor, Flavius Augustus Honorius, with Gothic auxiliaries under Ulfilas, crushed the Gallic rebellion with a siege of Arles.

* 349 – 359: Ursicinus, magister equitum under Constantius

* 359 – 360: Sabinianus, magister equitum under Constantius

* 351 – 361: Flavius Arbitio, magister equitum under Constantius

These Panegyrici are often attributed to Eumenius, magister memoriae ( private secretary ) to Constantius, resulting in the compromise name of pseudo-Eumenius.

Eumenius probably took his place, for it was from Autun that he went to be magister memoriae ( private secretary ) to Constantius Chlorus, whom he accompanied on several of his campaigns.
