Valentinian I “the Great” is an extremely fascinating character.
A man mostly forgotten by history, Valentinian was a great military strategist and was prone to incredible bursts of anger. However, underneath the harsh military exterior and the wrathful temper, he did have an extremely sensitive side, full of empathy and passion. When he was acclaimed Emperor by the troops on February 26th 364 AD, Valentinian was already an experienced military officer who had served both on the Rhine and in Mesopotamia, where he was promoted tribune of the elite Scutarii regiment. He was insecure, however, about the stability of his future reign, as immediately preceding him there had been a bloody civil conflict between the relatives of emperor Costantine. Therefore, to avoid further roman blood being shed, he made his loyal younger brother Valens co-emperor in the eastern half of the Roman Empire.
At Sirmium, in modern day Serbia, the two emperors divided their military personnel. The legions that were to serve Valentinian were dubbed Seniores while those under Valens were called Iuniores. Immediately, Valens’s power in the east was challenged by a usurper named Procopius, while Valentinian was occupied against the Alamanni tribe on the Rhine frontier. Valens was alone against Procopius, and as he had always been more of a follower than a leader, upon receiving news of the revolt, he faltered and even considered suicide. After this initial crisis of confidence, Valens strengthened his resolve to fight, ultimately managing to defeat Procopius in Anatolia (modern day Turkey) at the Battle of Thyatira.
Procopius was captured and beheaded on the spot by Valens’s officers, and his head was sent to Valentinian as a trophy. Meanwhile, Valens’s older brother was achieving victory after victory against the Alamanni in the West. An exceptional military man, Valentinian designed aggressive campaigns against the tribes living outside the Roman borders. One of these was the 368 AD expedition in which the Emperor gathered a massive army, including the Italian Comitatenses (professional troops) led by the Comes Italiae Sebastianus. He achieved a great victory at the Battle of Solicinium after which he then fortified the frontiers by building fortresses both inside and outside the established borders. By 370 AD, the empire seemed relatively stable after other successes against the Saxons.
Death for Valentinian came in the form of a bursting blood vessels during one of his angry outbursts while negotiating with tribes on the Rhine (14 November 375 AD). Power in the west fell to Valentinian’s young son Gratian while the east remained under Valens. Valens had obtained victories over the Goths under Athanaric in the Balkans by the year 369 AS while Armenia was invaded by the powerful Persian King of Kings Shapur 2. The bloody military encounters that followed ended in a stalemate in the East, with the persian armies kept at bay for the time being. In the year 376 AD, Valens was forced to rush to the Danube frontier, as the gothic tribe Tervingi had crossed the river and had defeated a roman force near Marcianople. After some initial success by the Roman general Sebastianus, the Goths, led by chieftain Fritigern, managed to defeat Valens’s imperial army at Adrianople, in Thrace.
Valens was among the dead, though his body was never found. Thus the Valentinian brothers came to an end, a period in history which has been undervalued to say the least, but was nevertheless rich of heroism, intrigue, imperial might and cruelty. This period is also proof of the Late Roman Empire’s military and civil might, charateristics that will be preserved in the Eastern half of the empire and deteriorate over time in the West after the demise of Valentinian.
