Everything about Theodosius I totally explained
Flavius Theodosius (
January 11,
347 –
January 17,
395), also called
Theodosius I and
Theodosius the Great (
Greek:
Θεοδόσιος Α΄ and
Θεοδόσιος ο Μέγας), was
Roman Emperor from 379 to 395. Reuniting the eastern and western portions of the empire, Theodosius was the last emperor of both the
Eastern and
Western Roman Empire. After his death, the two parts split permanently. He is also known for making
Christianity the official
state religion of the Roman Empire.
Career
Theodosius was born in
Cauca, in
Hispania (modern day
Coca,
Spain), to a senior military officer,
Theodosius the Elder. He accompanied his father to
Britannia to help quell the
Great Conspiracy in 368. He was military commander (
dux) of
Moesia, a Roman province on the lower
Danube, in 374. However, shortly thereafter, and at about the same time as the sudden disgrace and execution of his father, Theodosius retired to Cauca. The reason for his retirement, and the relationship (if any) between it and his father's death is unclear. It is possible that he was dismissed from his command by the emperor
Valentinian I after the loss of two of Theodosius' legions to the
Sarmatians in late 374.
The death of Valentinian I in 375 created political pandemonium. Fearing further persecution on account of his family ties, Theodosius abruptly retired to his family estates where he adapted to the life of a provincial aristocrat.
From 364 to 375, the Roman Empire was governed by two co-emperors, the brothers
Valentinian I and
Valens; when Valentinian died in 375, his sons,
Valentinian II and
Gratian, succeeded him as rulers of the Western Roman Empire. In 378, after
Valens was killed in the
Battle of Adrianople, Gratian appointed Theodosius to replace the fallen emperor as
co-augustus for the East. Gratian was killed in a rebellion in 383. After the death in 392 of Valentinian II, whom Theodosius had supported against a variety of usurpations, Theodosius ruled as sole emperor, defeating the usurper
Eugenius on
September 6,
394, at the
Battle of the Frigidus (
Vipava river, modern
Slovenia).
Family
By his first wife,
Aelia Flaccilla, he'd two sons,
Arcadius and
Honorius and a daughter, Aelia
Pulcheria; Arcadius was his heir in the east and Honorius in the west. Both Pulcheria and Aelia Flaccilla died in 385.
His second wife was
Galla, daughter of the emperor
Valentinian I. Theodosius and Galla had three children who were a son, Gratian born in 388 who died young and a daughter Aelia
Galla Placidia (392–450). Placidia was the only child who survived to adulthood and later become an Empress and the third child (a son), John died with his mother in childbirth in 394.
Diplomatic policy with the Goths
The
Goths and their allies (
Vandali,
Taifalae,
Bastarnae and the native
Carpi) entrenched in the
provinces of
Dacia and eastern
Pannonia Inferior consumed Theodosious' attention. The Gothic crisis was so dire that his co-Emperor Gratian relinquished control of the
Illyrian provinces and retired to
Trier in
Gaul to let Theodosius operate without hindrance. A major weakness in the Roman position after the defeat at
Adrianople was the recruiting of
barbarians to fight against other barbarians. In order to reconstruct the Roman Army of the West, Theodosius needed to find able bodied soldiers and so he turned to most capable men most readily at hand: the barbarians recently settled in the Empire. This caused many difficulties in the battle against barbarians since the newly recruited fighters had little to no loyalty to Theodosius.
Theodosius was reduced to the costly expedient of shipping his recruits to
Egypt and replacing them with more seasoned Romans, but there were still switches of allegiance that resulted in military setbacks. Gratian sent generals to clear the
dioceses of Illyria (
Pannonia and
Dalmatia) of Goths, and Theodosius was able finally to enter
Constantinople on
November 24,
380, after two seasons in the field. The final treaties with the remaining Gothic forces, signed
October 3,
382, permitted large contingents of primarily
Thervingian Goths to settle along the southern
Danube frontier in the
province of
Thrace and largely govern themselves.
The Goths now settled within the Empire had, as a result of the treaties, military obligations to fight for the Romans as a national contingent, as opposed to being fully integrated into the Roman forces. However, many Goths would serve in Roman legions and others, as
foederati, for a single campaign, while bands of Goths switching loyalties became a destabilizing factor in the internal struggles for control of the Empire. In the last years of Theodosius' reign, one of their emerging leaders named
Alaric, participated in Theodosius' campaign against
Eugenius in 394, only to resume his rebellious behavior against Theodosius' son and eastern successor,
Arcadius, shortly after Theodosius' death.
Civil wars in the Empire
After the death of
Gratian in 383, Theodosius' interests turned to the
Western Roman Empire, for the usurper
Magnus Maximus had taken all the provinces of the West except for Italy. This self-proclaimed threat was hostile to Theodosius' interests, since the reigning emperor
Valentinian II, Maximus' enemy, was his ally. Theodosius, however, was unable to do much about Maximus due to his still lacking military and was forced to keep his attention on local matters. However when Maximus began an invasion into Italy in 387, Theodosius was forced to take action. The armies of Theodosius and Maximus met in 388 at Poetovio and Maximus was defeated. On
August 28,
388 Maximus was executed.
Trouble arose again, after Valentinian was found hanging in his room. It was claimed to be a suicide by the
magister militum,
Arbogast. Arbogast, unable to assume the role of emperor, elected
Eugenius, a former teacher of rhetoric. Eugenius started a program of restoration of the
Pagan faith, and sought, in vain, Theodosius' recognition. In January of 393, Theodosius gave to his son
Honorius the full rank of Augustus in the West, suggesting Eugenius' illegitimacy.
Theodosius campaigned against Eugenius. The two armies faced at the
Battle of Frigidus in September of 394. The battle began on
September 5,
394 with Theodosius' full frontal assault on Eugenius' forces. Theodosius was repulsed and Eugenius thought the battle to be all but over. In Theodosius' camp the loss of the day decreased morale. It is said that Theodosius was visited by two "heavenly riders all in white"
The Emperor Valens had favored the group who used the
homoios formula; this
theology was prominent in much of the East and had under the sons of Constantine the Great gained a foothold in the West. Theodosius, on the other hand, cleaved closely to the Nicene Creed: this was the line that predominated in the West and was held by the important
Alexandrian church.
Establishment of Nicene orthodoxy
On
November 26,
380, two days after he'd arrived in Constantinople, Theodosius expelled the non-Nicene bishop,
Demophilus of Constantinople, and appointed
Meletius patriarch of Antioch, and
Gregory of Nazianzus, one of the
Cappadocian Fathers from
Antioch (today in Turkey), patriarch of Constantinople. Theodosius had just been baptized, by bishop
Acholius of Thessalonica, during a severe illness, as was common in the early Christian world.
In February he and Gratian published an edict that all their subjects should profess the faith of the bishops of Rome and Alexandria (for example, the Nicene faith). The move was mainly a thrust at the various beliefs that had arisen out of Arianism, but smaller dissident sects, such as the
Macedonians, were also prohibited.
In May 381, Theodosius summoned a new ecumenical council at Constantinople to repair the schism between East and West on the basis of Nicean orthodoxy. "The council went on to define orthodoxy, including the mysterious Third Person of the Trinity, the Holy Ghost who, though equal to the Father, 'proceeded' from Him, whereas the Son was 'begotten' of Him." The council also "condemned the Apollonian and Macedonian heresies, clarified church jurisdictions according to the civil boundaries of dioceses and ruled that Constantinople was second in precedence to Rome." His first attempt to inhibit paganism was in 381 when he reiterated Constantine's ban on sacrifice. But for the most part in his early reign he was very tolerant on pagans in the Empire.
In 388 he sent a prefect to Syria, Egypt, and Asia Minor with the aim of breaking up pagan associations and the destruction of their temples. The
Serapeum at Alexandria was destroyed during this campaign. In a series of decrees called the "Theodosian decrees" he progressively declared that those Pagan feasts that hadn't yet been rendered Christian ones were now to be workdays (in 389). In 391, he reiterated the ban of
blood sacrifice and decreed "no one is to go to the sanctuaries, walk through the temples, or raise his eyes to statues created by the labor of man". The temples that were thus closed could be declared "abandoned", as Bishop
Theophilus of Alexandria immediately noted in applying for permission to demolish a site and cover it with a Christian church, an act that must have received general sanction, for
mithraea forming crypts of churches, and temples forming the foundations of 5th century churches appear throughout the former Roman Empire. Theodosius participated in actions by Christians against major Pagan sites: the destruction of the gigantic
Serapeum of Alexandria and its library by a mob in around 392, according to the Christian sources authorized by Theodosius (
extirpium malum), needs to be seen against a complicated background of less spectacular violence in the city:
Eusebius mentions street-fighting in Alexandria between Christians and non-Christians as early as 249, and non-Christians had participated in the struggles for and against
Athanasius in 341 and 356. "In 363 they killed Bishop George for repeated acts of pointed outrage, insult, and pillage of the most sacred treasures of the city."
By decree in 391, Theodosius ended the subsidies that had still trickled to some remnants of Greco-Roman civic Paganism too. The
eternal fire in the Temple of
Vesta in the
Roman Forum was extinguished, and the
Vestal Virgins were disbanded. Taking the
auspices and practicing
witchcraft were to be punished. Pagan members of the
Senate in Rome appealed to him to restore the
Altar of Victory in the Senate House; he refused. After the last
Olympic Games in 393, Theodosius cancelled the games, and the reckoning of dates by
Olympiads soon came to an end. Now Theodosius portrayed himself on his coins holding the
labarum.
The apparent change of policy that resulted in the "Theodosian decrees" has often been credited to the increased influence of
Ambrose,
bishop of Milan. It is worth noting that in 390 Ambrose had excommunicated Theodosius, who had recently ordered the
massacre of 7,000 inhabitants of
Thessalonica, in response to the assassination of his military governor stationed in the city, and that Theodosius performed several months of public penance. The specifics of the decrees were superficially limited in scope, specific measures in response to various petitions from Christians throughout his administration.
Some modern historians question the consequences of the laws against pagans.
Death
Theodosius died, after battling the vascular disease
oedema, in
Milan on
January 17,
395.
Ambrose organized and managed Theodosius's lying in state in Milan. Ambrose delivered a
panegyric titled
De Obitu Theodosii before
Stilicho and
Honorius in which Ambrose detailed the suppression of heresy and paganism by Theodosius. Theodosius was finally laid to rest in Constantinople on
November 8,
395.
