* September 21 – Emperor Valentinian III stabs his commander-in-chief Flavius Aetius to death during a meeting of the imperial council at Ravenna.

Regardless, the powerful Magister militum Aetius had forced Valentinian to betroth Placidia to his own son Gaudentius, so Olybrius could not have married her before Aetius ' death.

Marcellinus was the comes rei militaris ( governor ) of Illyricum, but he had become practically independent since the death of Aetius, non recognising the imperial authority ; Majorian had convinced him to accept him as Emperor and even to collaborate with his troops with the military recovery of the Empire.

He chose as accomplices Optilia and Thraustila, two Scythians who had fought under the command of Aetius and who, after the death of their general, had been appointed as Valentinian ’ s escort.

Maximus easily convinced them that Valentinian was the only one responsible for the death of Aetius, and that the two soldiers must avenge their old commander, while at the same time also promising them a reward for the betrayal of the Emperor.

In particular, the army ’ s support was split between three main candidates: Maximianus, the former domesticus (" bodyguard ") of Aëtius, who was the son of an Egyptian merchant named Domninus who had become rich in Italy ; the future emperor Majorian, who commanded the army after the death of Aetius and who had the backing of the Empress Licinia Eudoxia ; and Maximus himself, who had the support of the Roman Senate and who in the end, on 17 March, defeated his rivals and secured the throne by distributing money to officials of the imperial palace.

Aetius returned, three days after Joannes ' death, at the head of a substantial Hunnic army which made him the most powerful general in Italia.

In 454 Aetius was personally stabbed to death by Valentinian, who was himself murdered by the dead general's supporters a year later.

The Battle of Adrianople in 378, the death of Theodosius I in 395 ( the last time the Roman Empire was politically unified ), the crossing of the Rhine in 406 by Germanic tribes, the execution of Stilicho in 408, the sack of Rome in 410, the death of Constantius III in 421, the death of Aetius in 454, the second sack of Rome in 455, and the death of Majorian in 461 are emphasized by various historians.

Once Flavius Aetius learned of this plan, he rusticated Majorian to his estates at some date before 451, and was only recalled to Rome after Aetius ' death.

He studied theology at Alexandria under Aetius, and afterwards came under the influence of Eudoxius of Antioch, who ordained him deacon.

After some fighting, Placidia and Aetius came to an agreement ; the Huns were paid off and sent home, while Aetius received the position of magister militum.

* September 21 – Flavius Aetius, Roman general ( magister militum )

Aetius continues arguments in his theses 19, 20, 21, 24 and 25, that his negative definition of God is not evidence of privation.

Aetius also finds it troubling that if Jesus is unchangeable in nature by the reason of the one who generated him, then ingeneracy is unchangeable essence, not by the virtue of its will, but of its internal ranking or state of being ‘ un generated ’ 21.

* 454 – Flavius Aetius, Roman general ( b. 396 )

Marcellinus was a powerful figure in the Western Roman Empire, rebelling in 454 against the Emperor Valentinian III after the latter's assassination of Flavius Aetius.

* 433 – 454: Flavius Aetius

The text describes Aetius as being consul for the third time, dating the message to the period between 446, when he held his third consulate, and 454, when he held his fourth.

It occurred as Aetius was presenting some financial statement before the Emperor, when Valentinian, suddenly leaping from his throne, accused him of treason.

He only flashed once into action, when, piqued by the presumption of Aetius in aspiring to connect himself with the imperial family, he struck him down.

One of their groups, under Goar, joined the Roman forces of Flavius Aetius to fight Attila when he invaded Gaul in 451, taking part in the Battle of Châlons under their king Sangiban.

Here he lived until 451, when the Huns, led by Attila, invaded the Western Roman Empire ; Avitus persuaded Theodoric into an alliance with Rome, and the combined forces of Theodoric and Aetius defeated Attila in the Battle of Châlons ; Theodoric died in the battle.

Despite their new status as foederati, Burgundian raids into Roman upper Gallia Belgica became intolerable and were ruthlessly brought to an end in 436, when the Roman general Flavius Aetius called in Hun mercenaries who overwhelmed the Rhineland kingdom ( with its capital at the old Celtic Roman settlement of Borbetomagus, now called Worms ) in 437.

There was an intermediate period under the Late Roman Empire and Byzantine Empire when the title was given to governors in the Western parts of the Empire, such as Sicily — Stilicho, Aetius and other 5th-century magistri militari usefully exemplify the role and scope of the patricius at this point.

Aetius states in theses 4: “ If the Deity remains everlastingly in ingenerate nature, and the offspring is everlastinglingy offspring, then the perverse doctrine of “ homousion ” and the “ homoiousion ” will be demolished ; incomparability in essence is established when each nature abides unceasingly in the proper rank of its nature 10 .” Aetius also spends a lot of time in these theses ’ outlining that ingeneration is not a privation.

He continues this same type of logic when in thesis 26 he states that “ If " The Ingenerate " is a mere name with God, but its mere utterance elevates the substance of God over against all the generated beings …”, this is showing again that Aetius believes that the name associated with God elevates him to a position of superiority over all other beings 15.

Aetius was given the duty of relieving Orléans by Emperor Valentinian III.

* March 16 – Emperor Valentinian III, age 35, is assassinated by two Hunnic retainers of the late Flavius Aetius, ending the Theodosian Dynasty.

Furthermore, as Emperor, Majorian could have led the army by himself, thus freeing him from the dangerous bond with a powerful general, as Valentinian had been obliged to contract with Aetius.

However, Ricimer could expect to exert a great influence on the new Western Emperor, because of their relationship, dating back to the time of their service under Aetius, and of his control on the army as magister militum.

Aetius was given the duty of relieving Orléans by Emperor Valentinian III.

Aetius also attempted to consolidate his position " by compelling the Emperor to swear to friendship with him and to agree to betroth Placidia to his own younger son Gaudentius.

Aetius was removed from his office by his brother heretics, yet he was later recalled and welcomed by the Emperor Julian 2.

Aetius was defending himself against Neoplatonists in this regard, and perhaps he could have had a close relationship with the Emperor Julian, which would have supposedly been upsetting to the Neoplatonists as well 11.

* Flavius Aetius, Roman general ( magister militum ), in the service of emperor Valentinian III, holds power in Rome for twenty years.

Attila claims his lost property, but Valentinian and Flavius Aetius ( magister militum ) refuse this request.

The following year, Valentinian was killed by some soldiers who had served under Aetius, probably instigated by the Patricius Petronius Maximus, who succeeded to obtain the throne.

In that year, in fact, Valentinian III killed Aetius with his own hands, but, fearing a revolt in Aetius ' troops, he called Majorian back in office to quell them.

The following year Valentinian III was killed by two former officers of Aetius ' staff.
