Gratian (Latin: Gratianus; 18 April 359 – 25 August 383) was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.
Following the death of the emperor Jovian, on 26 February 364, Valentinian was proclaimed Augustus (emperor).[7] Within a month, motivated by senior officers, he proclaimed his brother Valens, Gratian's uncle, Augustus of the Eastern empire.[7] Gratian was appointed consul in 366 and was entitled nobilissimus puer by his father.[a][8] Gratian was seven when entitled nobilissimus puer, which indicated he was to be proclaimed Augustus.[8] His tutor was the rhetorAusonius, who mentioned the relationship in his epigrams and a poem.[9]
Reign
In summer 367, Valentinian became ill at Civitas Ambianensium (Amiens), raising questions about his succession. On recovery, he presented his then eight-year-old son to his troops on 24 August, as his co-augustus, passing over the customary initial step of caesar.[10][8][11]

When a party of Alamanni visited Valentinian's headquarters to receive the customary gifts towards the end of 364, Ursatius, the magister officiorum made them an offering they considered inferior to that of his predecessor. Angered by Ursatius' attitude, they vowed revenge and crossed over the Rhine into Roman Germania and Gaul in January 365, overwhelming the Roman defences.[14] Although at first unsuccessful, eventually Jovinus, the magister equitum in Gaul inflicted heavy losses on the enemy at Scarpona (Dieulouard) and at Catalauni (Châlons-sur-Marne), forcing them to retire.[14] An opportunity to further weaken the Alamanni occurred in the summer of 368, when king Vithicabius was murdered in a coup, and Valentinian and his son Gratian crossed the river Moenus (the Main) laying waste to Alamannic territories.[15][16] Gratian was awarded the victory titles of Germanicus Maximus and Alamannicus Maximus, and Francicus Maximus and Gothicus Maximus in 369.[15]
Valentinian fortified the frontier from Raetia in the east to the Belgic channel, but the construction was attacked by Alamanni at Mount Pirus (the Spitzberg, Rottenburg am Neckar). In 369 (or 370) Valentinian then sought to enlist the help of the Burgundians, who were involved in a dispute with the Alamanni, but a communication failure led to them returning to their lands without joining forces with the Romans.[16] It was then that the magister equitum, Theodosius the Elder and his son Theodosius (the Theodosi) attacked the Alamanni through Raetia, taking many prisoners and resettling them in the Po Valley in Italy.[16] Valentinian made one attempt to capture Macrianus in 372, but eventually made peace with him in 374.[17]
The necessity to make peace was the increasing threat from other peoples, the Quadi and the Sarmatians. Valentinian's decision to establish garrisons across the Danube had angered them, and the situation escalated after the Quadi king, Gabinus, was killed during negotiations with the Romans in 374. Consequently, in the autumn, the Quadi crossed the Danube plundering Pannonia and the provinces to the south.[17] The situation deteriorated further once the Sarmatians made common cause inflicting heavy losses on the Pannonica and Moesiaca legions.[17] However, on encountering Theodosius' forces on the borders of Moesia in the eastern Balkans, which had previously defeated one of their armies in 373, they sued for peace.[17] Valentinian mounted a further offensive against the Quadi in August 375, this time using a pincer movement, one force attacking from the northwest, while Valentinian himself headed to Aquincum (Budapest), crossed the Danube and attacked from the southeast.[17] This campaign resulted in heavy losses to the enemy, following which he returned to Aquincum and from there to Brigetio (Szőny, Hungary) where he died suddenly in November.[20]
Senior augustus
When his father died on 17 November 375, Gratian inherited the administration of the western empire.[21] Days later, Gratian's half-brother Valentinian was acclaimedaugustus by troops in Pannonia.[22] He was forced to accept the proclamation, though he did supervise his younger brother's upbringing.[23] Despite Valentinian being given nominal authority over the praetorian prefectures of Italy, Illyricum, and Africa, Gratian ruled the western Roman empire himself.[24] His tutor Ausonius became his quaestor, and together with the magister militum, Merobaudes, the power behind the throne.[21] Neither Gratian or Valentinian travelled much, which was thought to be due to not wanting the populace to realise how young they were. Gratian is said to have visited Rome in 376, possibly to celebrate his decennalia on 24 August,[15] but whether the visit actually took place is disputed.[21]

Gratian's uncle Valens, returning from a campaign against the Sasanian Empire, had sent a request to Gratian for reinforcements against the Goths.[25] According to Ammianus Marcellinus, Valens also requested that Sebastianus be sent to him for the war, though according to Zosimus Sebastianus went to Constantinople of his own accord as a result of intrigues by eunuchs at the western court.[13] Once Gratian had put down the invasions in the west in early 378, he notified Valens that he was returning to Thrace to assist him in his struggle against the Goths. Late in July, Valens was informed that the Goths were advancing on Adrianople (Edirne) and Nice, and started to move his forces into the area. However, Gratian's arrival was delayed by an encounter with Alans at Castra Martis, in Dacia in the western Balkans. The forces Gratian sent never reached Valens due to its commander feigning illness.[26] Weeks later, Gratian had arrived in Castra Martis with a few thousand men, by which time Valens was at Adrianople (Latin: Hadrianopolis; Turkish: Edirne).[27] Encouraged by his advisors to claim victory without sharing the glory with Gratian, as well as being misinformed about the number of enemy troops,[28] Valens attacked the Gothic army and as a result thousands[b] of Romans died in the Battle of Adrianople along with Sebastianus and the emperor himself.[26][29][13]

In the immediate aftermath of Adrianople, Gratian issued an edict of tolerance at Sirmium, restoring bishops exiled by Valens and ensuring religious freedoms to all religions.[31] Following the battle, the Goths raided from Thrace in 378 to Illyricum the following year.[32][33] Convinced that one emperor alone was incapable of repelling the inundation of foes on several different fronts, Gratian, now senior augustus following Valens's death,[34] appointed Theodosius Iaugustus on 19 January 379 to govern the east.[35][36] On 3 August that year, Gratian issued an edict against heresy.[15]
On 27 February 380, Gratian, Valentinian II, and Theodosius issued the Edict of Thessalonica.[37] This edict made Nicene Christianity the only legal form of Christianity and outlawed all other forms of religion,[37] ending a period of widespread religious tolerance that had existed since the death of Julian.[38]Zosimus' report that Gratian refused the robe of office of the pontifex maximus has been doubted by modern scholars, because there is no other mention of such a garment associated with the priesthood.[39] Emperors from Gratian to Marcian styled themselves as pontifex inclytus, "honorable pontiff". The title of pontifex maximus was not adopted by the bishops of Rome until the Renaissance.[40][41]
In September 380, the augusti Gratian and Theodosius met, returning the Roman diocese of Dacia to Gratian's control and that of Macedonia to Valentinian II.[15][42] The same year, Gratian won a victory, possibly over the Alamanni, that was announced officially at Constantinople.[15]
By 380, the Greuthungi tribe of Goths moved into Pannonia, only to be defeated by Gratian.[32] Consequently, the Vandals and Alemanni were threatening to cross the Rhine, now that Gratian had departed from the region.[43] With the collapse of the Danube frontier[c] under the incursions of the Huns and Goths, Gratian moved his seat from Augusta Treverorum (Trier) to Mediolanum (Milan) in 381.[44] He became increasingly aligned with the city's bishop, Ambrose, and the Roman Senate, shifting the balance of power within the factions of the western empire.[45][46]
In 382, Gratian issued edicts that removed the statue of the winged goddess Victory from the Senate floor,[47] removed the privileges of Vestal Virgins,[48] and confiscated money designated for sacrifices and ceremonies.[49] He declared that all of the pagan temples and shrines were to be confiscated by the government and that their revenues were to be joined to the property of the treasury.[50] This resulted in protests from the Roman Senate led by Symmachus, which in turn was counter-protested by Christian senators led by Pope Damasus.[51]
On 16 January 383 Theodosius made his son Arcadius co-emperor, evidently without Gratian's approval as he never recognized the promotion on his coinage.[52][53] Within the same year, Gratian's wife Constantia died, and he remarried to Laeta.[54] Both marriages remained childless.[55][d]
In the summer of 383 Gratian was again at war with the Alamanni in Raetia.[57][53] Gratian alienated the army by his favouritism towards his Alan deserters, whom he made his bodyguards and to whom he gave military commands.[e] Other criticisms of his behavior were that he surrounded himself with bad company[44][59] and neglected the affairs of state,[60] preferring to have fun.[57][61][f] Shortly after, the Roman general Magnus Maximus had raised the standard of revolt in Britain and invaded Gaul with a large army.[63] Maximus, who had served under the comes Theodosius and had won a victory over the Picts in 382, was proclaimed augustus and crossed the channel, encamping near Paris. There, his forces encountered Gratian, but much of the latter's army defected to the usurper, forcing Gratian to flee.[52][63][64]

Death and burial
Gratian was pursued by Andragathius, Maximus' magister equitum and killed at Lugdunum (Lyon) on 25 August 383,[52][63][64] supposedly against orders.[65] Maximus then established his court at the former imperial residence in Trier.[60] On the death of Gratian, the 12 year old Valentinian II became the sole legitimate augustus in the west.[66]
Maximus initially kept Gratian's body for political reasons, and Ambrose's second embassy to him in 385 or 386 to recover it was unsuccessful.[67][68] It would not be until 387, possibly even after the death of Magnus Maximus, that Gratian's remains were interred at Mediolanum in the imperial mausoleum.[69] Gratian was deified in Latin: Divus Gratianus, lit. 'the Divine Gratian'.[15][70]
