'' '' and a globe supporting a
Victory, who crowns him with a
laurel wreath Both emperors were briefly ill, delaying them in Constantinople. As soon as they recovered, the two
augusti travelled together through
Adrianople and
Naissus to
Mediana, where they divided their territories. Valens obtained the eastern half of the Empire:
Greece, the
Balkans,
Egypt,
Anatolia and the
Levant as far as the border with the
Sasanian Empire. Valentinian took the western half, where the
Alemannic wars required his immediate attention. The brothers began their consulships in their respective capitals, Constantinople and
Mediolanum (
Milan). In the summer of 365, the
365 Crete earthquake and ensuing tsunami caused destruction around the Eastern Mediterranean. The empire had recently retreated from most of its holdings in
Mesopotamia and
Armenia, because of a treaty that Jovian had made with
Shapur II of the Sasanian Empire. Valens' first priority after the winter of 365 was to move east in hopes of shoring up the situation.
Usurpation of Procopius (365–366) Recent tax increases, and Valens' dismissal of Julian's popular minister
Salutius, contributed to a general disaffection and to the acceptability of a revolution. With the emperor absent from the imperial city,
Procopius, a maternal cousin of Julian, declared himself
augustus on 28 September 365. Procopius had held office under Constantius II and Julian and was rumored to have been Julian's intended successor, despite how he had died without naming one. Jovian, aside from depriving him of his command, took no measures against this potential rival, but Valentinian regarded Procopius with hostility. Procopius met the danger from the new emperors with his own bid for power, emphasizing his connection to the revered
Constantinian Dynasty: during his public appearances he was always accompanied by Constantia, the posthumous daughter of Constantius II, and her mother
Faustina, the
dowager empress. News of the revolt reached Valens at Caesarea (
Kayseri) in Cappadocia, after most of his troops had already crossed the
Cilician Gates into
Syria. His first reaction was despair, and he considered abdication and perhaps even suicide. Procopius quickly gained control of the provinces of
Asia and
Bithynia, winning increasing support for his insurrection. Valens recovered his nerve and sent an army to Constantinople; according to Ammianus Marcellinus, the soldiers defected to Procopius, whose use of his Constantinian hostages had met with some success. The treaty seems to have largely cut off relations between Goths and Romans, confining
trade and the exchange of troops for tribute. )
Persian War: 373 As mentioned before, among Valens' reasons for contracting a hasty and not entirely favorable peace in 369 was the deteriorating state of affairs in the East. Jovian had surrendered Rome's much disputed claim to control over Armenia in 363, and
Shapur II was eager to make good on this new opportunity. The Persian emperor began enticing Armenian lords over to his camp and eventually forced the defection of the
Arsacid Armenian king,
Arshak II (Arsaces II), whom he quickly arrested and incarcerated. The Armenian nobility responded by asking Valens to return Arshak's son,
Pap. Valens agreed and sent Pap back to Armenia, but as these events took place during the war with the Goths he could not support him militarily. Pap and his followers took refuge in the mountains while
Artaxata, the Armenian capital, and the city of Artogerassa along with several strongholds and castles were destroyed. The following spring twelve legions were sent under
Terentius to regain Iberia and to garrison Armenia near Mount Npat. When Shapur counterattacked into Armenia in 371, his forces were bested by Valens' generals
Traianus and
Vadomarius and the Armenian
sparapet (general)
Mushegh Mamikonian at
Bagavan and
Gandzak. Valens had overstepped the 363 treaty and then successfully defended its transgression. A truce settled after the 371 victory held as a quasi-peace for the next five years while Shapur was forced to deal with a
Kushan invasion on his eastern frontier. Meanwhile, troubles broke out with the boy-king Pap, who purportedly had the Armenian patriarch
Nerses assassinated and demanded control of a number of Roman cities, including
Edessa. Controversy also ensued over the issue of the appointment of a new patriarch of Armenia, with Pap appointing a candidate without the traditional approval from Caesarea. Pressed by his generals and fearing that Pap would defect to the Persians, Valens made an unsuccessful attempt to capture the prince and later had him executed inside Armenia. In his stead, Valens imposed another Arsacid,
Varazdat, who ruled under the regency of the
sparapet Mushegh Mamikonian, a friend of Rome. None of this sat well with the Persians, who began agitating again for compliance with the 363 treaty. As the eastern frontier heated up in 375, Valens began preparations for a major expedition. Meanwhile, trouble was brewing elsewhere. In
Isauria, the mountainous region of western
Cilicia, a major revolt had broken out in 375 which diverted troops formerly stationed in the East. Furthermore, by 377, the
Saracens under
Queen Mavia had broken into revolt and devastated a swath of territory stretching from
Phoenicia and
Palestine as far as the
Sinai. Though Valens successfully brought both uprisings under control, the opportunities for action on the eastern frontier were limited by these engagements closer to home. in

Later reign: 373–376 Valens became the senior
augustus on 17 November 375, after his older brother Valentinian died suddenly at Brigetio (
Szőny) while on campaign against the
Quadi in Pannonia. In the west, Valentinian was succeeded by his elder son
Gratian, co-emperor since 367, and his younger son
Valentinian II, whom the army on the Danube proclaimed
augustus without consulting Gratian or Valens.
Second Gothic War: 376–378 Valens' eastern campaign required an ambitious recruitment program, designed to fill gaps left in his mobile forces when troops were transferred to the Western Empire in 374. Meanwhile, migrations of the
Huns began to displace the Goths, who sought Roman protection. Valens opened the campaign with arrangements aimed at building his troop strength and gaining a toehold in Thrace, then moved out to Adrianople, from whence he marched against the confederated barbarian army. Although negotiations were attempted, these broke down when a Roman unit sallied forth and carried both sides into battle. Valens had left a sizeable guard with his baggage and treasures, depleting his force. His right cavalry wing arrived at the Gothic camp sometime before the left wing arrived. It was a very hot day and the Roman cavalry was engaged without strategic support, wasting its efforts and suffering in the heat. Meanwhile, Fritigern once again sent an emissary of peace in his continued manipulation of the situation. The resultant delay meant that the Romans present on the field began to succumb to the heat. The army's resources were further diminished when an ill-timed attack by the Roman archers made it necessary to recall Valens' emissary,
comes Richomeres. The archers were beaten and retreated in humiliation. Returning from foraging to find the battle in full swing, Gothic cavalry under the command of Alatheus and Saphrax now struck and, in what was probably the most decisive event of the battle, the Roman cavalry fled. From here, Ammianus gives two accounts of Valens' demise. In the first account, Ammianus states that Valens was "mortally wounded by an arrow, and presently breathed his last breath" (XXXI.12). His body was never found or given a proper burial. In the second account, Ammianus states the Roman infantry was abandoned, surrounded and cut to pieces. Valens was wounded and carried to a small wooden hut. He died when the Goths, evidently unaware of the prize within, set the hut on fire (XXXI.13.14–16). A third, apocryphal, account states that Valens was struck in the face by a Gothic dart and then perished while leading a charge. He wore no helmet, in order to encourage his men. This action turned the tide of the battle which resulted in a
tactical victory but a strategic loss. The church historian
Socrates likewise gives two accounts for the death of Valens. Some have asserted that he was burnt to death in a village whither he had retired, which the barbarians assaulted and set on fire. But others affirm that having put off his imperial robe he ran into the midst of the main body of infantry; and that when the cavalry revolted and refused to engage, the infantry were surrounded by the barbarians, and completely destroyed in a body. Among these it is said the Emperor fell, but could not be distinguished, in consequence of his not having on his imperial habit. When the battle was over, two-thirds of the eastern army lay dead. Many of their best officers had also perished. What was left of the army of Valens was led from the field under the cover of night by
comes Richomeres and general Victor.
J. B. Bury, a noted historian of the period, provides a specific interpretation on the significance of the battle: it was "a disaster and disgrace that need not have occurred." For Rome, the battle incapacitated the government. Emperor Gratian, nineteen years old, was unable to deal with the catastrophe, until he appointed
Theodosius I. The total defeat cost the administration important precious metal resources, as bullion had been centralized with the imperial court. Valens was
