Background

Valentinian I, after his death, in 375, was succeeded in the west jointly by two of his two sons, Gratian and Valentinian II. [2] Gratian, who was 17 years old at his accession, began his rule well, subduing the Alemans in a hard-fought campaign beyond the Rhine in 377 and reacting with foresight and prudence to the death of his uncle Valens at the battle of Adrianople, appointing Theodosius I, a skillful commander, with the authority of Augustus to contain the Gothic irruption. [3] Gratian, however, soon alienated his western subjects by his disgraceful favoritism towards his Scythian bodyguards, and his neglect of public business, [4] with the result that in 383 the British legions rebelled, and proclaimed emperor Magnus Maximus. Maximus shortly invaded Gaul and deposed and killed Gratian, meeting little or no resistance from Gratian's disaffected subjects. [5] Theodosius, Gratian's appointee in the east, was now faced with the choice between ingratitude to his murdered co-Augustus and a civil war which might, given the barbarian menace, bring the empire to final destruction. He chose to accept Maximus as emperor in the west, with the sole stipulation that young Valentinian II, (represented, for reason of his extreme youth, by his mother Justina) be permitted to rule as an independent third Augustus in Italy; Maximus accepted, and war was for the time avoided. [6]

Four years later (387), after Justina had alienated Italy by her Arianism and her religious conflicts with the popular bishop Ambrose of Milan, Maximus saw his opportunity to complete his usurpation of the west by conquering Italy from the 16 year-old Valentinian. [7] To effect this most easily, he employed the pretense of reinforcing the Rhaetian frontier against the barbarians to introduce his troops over the Alps into Italy, after which, with the passes secure behind him, he treacherously turned to march on Milan, Valentinian's capital. Justina and her son only escaped by a frantic flight to Aquileia, whence they proceeded by boat to Thessalonica in Greece, entrusting themselves to Theodosius' magnanimity; in the meantime, Italy succumbed to Maximus. [8]

The Battle

Theodosius at once departed from Constantinople to greet the imperial fugitives at Thessalonica. According to Gibbon, Theodosius hesitated some time whether to risk a war against the usurper with his formidable Germanic auxiliaries, but was ultimately swayed by his love for Valentinian's sister, Galla, to take up the fallen family's cause. Justina only too gladly consented to Theodosius' marriage with her daughter, and after a hurried ceremony, Theodosius set himself to begin the war against Maximus. [9]

The latter, in the meantime, after besieging Aemona on the frontiers of Italy and Illyricum, had advanced to occupy Siscia, thinking to repel Theodosius on the Save river. During his years as emperor of the west he had, as previously intimated, amassed a powerful force of German mercenaries, in addition to which he had the entire forces of Gaul, Britain, and Spain at his disposal. Theodosius I, on the other hand, possessed the superiority of naval power, the alliance of approximately 40,000 Gothic Foederati (lately settled in Thrace and Asia-Minor at the end of the Gothic war), and a strong body of Huns and Alani as auxiliaries. [10]

Whichever side, however, possessed the material advantage, the superiority of generalship was decisive. While Maximus delayed in apprehension, Theodosius, spreading rumors of an impending invasion of Italy from the sea, boldly advanced through Illyricum with his main army, at the same time sending his Frankish lieutenant Arbogastes further north through Rhaetia along the Danube into Gaul. [11]

The entire campaign, culminating in the battle on the Save near Siscia, was over within two months. On the very day that Theodosius reached the Save he forced the passage against Maximus' superior forces on the opposite bank. The following day, Maximus' lieutenant (and brother) Marcellinus launched a counter-attack to hurl Theodosius back into the river, and the fighting lasted the whole day; ultimately, the usurper's army was routed, and Maximus fled, escaping to Aquilia. [12]

A feature of the battle is the use by Theodosius of Hun mercenaries, who apparently were stirrup-equipped horse archers. Maximus' Western Roman Empire forces probably lacked such troops.

After his decisive victory Theodosius, following in swift pursuit, besieged the tyrant in his refuge of Aquilia, an important fortress west of the Julian Alps. The garrison soon surrendered, delivering Maximus in chains to the axe of Theodosius' justice. The death of Maximus (July 28th), and of his son Victor (captured and executed by Arbogastes), brought the civil war to a swift conclusion. [13] [14]

Honorius (emperor) Augustus of the Western Roman Empire

Honorius was Western Roman Emperor from 395 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla, and brother of Arcadius, who was the Eastern Emperor from 395 until his death in 408. During his reign, Rome was sacked for the first time in almost 800 years.

Theodosius I Roman Emperor from 379 to 395

Theodosius I, also known as Theodosius the Great, was a Roman Emperor from 379 to 395, and the last emperor to rule over both the Eastern and the Western halves of the Roman Empire. On accepting his elevation, he campaigned against Goths and other barbarians who had invaded the Empire. His resources were not sufficient to destroy them or drive them out, which had been Roman policy for centuries in dealing with invaders. By treaty, which followed his indecisive victory at the end of the Gothic War, they were established as foederati, autonomous allies of the Empire, south of the Danube, in Illyricum, within the Empire's borders. They were given lands and allowed to remain under their own leaders, a grave departure from Roman hegemonic ways. This turn away from traditional policies was accommodationist and had grave consequences for the Western Empire from the beginning of the century, as the Romans found themselves with the impossible task of defending the borders and dealing with unruly federates within. Theodosius I was obliged to fight two destructive civil wars, successively defeating the usurpers Magnus Maximus in 387–388 and Eugenius in 394, though not without material cost to the power of the Empire.

The 380s decade ran from January 1, 380, to December 31, 389.
