Valens

Valens (Ouálēs; 328 – 9 August 378) was Roman emperor from 364 to 378. Following a largely unremarkable military career, he was named co-emperor by his elder brother Valentinian I, who gave him the eastern half of the Roman Empire to rule. In 378, Valens was defeated and killed at the Battle of Adrianople against the invading Goths, which astonished contemporaries and marked the beginning of barbarian encroachment into Roman territory. As emperor, Valens continually faced threats both internal and external. He defeated, after some dithering, the usurper Procopius in 366, and campaigned against the Goths across the Danube in 367 and 369. In the following years, Valens focused on the eastern frontier, where he faced the perennial threat of Persia, particularly in Armenia, as well as additional conflicts with the Saracens and Isaurians. Domestically, he inaugurated the Aqueduct of Valens in Constantinople, which was longer than all the aqueducts of Rome. In 376–77, the Gothic War broke out, following a mismanaged attempt to settle the Goths in the Balkans. Valens returned from the east to fight the Goths in person, but lack of coordination with his nephew, the western emperor Gratian (Valentinian I's son), as well as poor battle tactics, led to Valens and much of the eastern Roman army dying at a battle near Adrianople in 378. Although Valens is described as indecisive, impressionable, a mediocre general and overall "utterly undistinguished", he was nonetheless a conscientious and capable administrator, and a notable achievement of his was to significantly relieve the burden of taxation on the population. At the same time, his suspicious and fearful disposition, and excessive concern for personal safety, resulted in numerous treason trials and executions, which heavily stained his reputation. In religious matters, Valens favored a compromise between Nicene Christianity and the various non-trinitarian Christian sects, and interfered little in the affairs of the pagans.
