17. A much more important change took place in the eastern world; the first admission of the barbarian tribes into[Pg. 369] the empire, which they finally destroyed.
A.D. 376.
The nation of the Goths had been from remote ages settled on the banks of the Danube, and were by that river divided into two nations, the Ostrogoths on the east, and the Visigoths on the west. They had for many years enjoyed the blessings of profound peace under the government of their king Herman'ric, when they were suddenly alarmed by the appearance of vast hordes of unknown enemies on their northern and eastern frontiers. These were the Huns, a branch of the great Mongolian race, which, from the earliest time, had possessed the vast and wild plains of Tartary. Terrified by the numbers, the strength, the strange features and implacable cruelty of such foes, the Goths deserted their country, almost without attempting opposition, and supplicated the emperor Va'lens to grant them a settlement in the waste lands of Thrace. This request was cheerfully granted, and the eastern empire was supposed to be strengthened by the accession of a million of valiant subjects, bound both by interest and gratitude to protect its frontiers.
18. But the avarice of Va'lens and his ministers defeated these expectations; instead of relieving their new subjects, the Roman governors took advantage of their distress to plunder the remains of their shattered fortunes, and to reduce their children to slavery. Maddened by such oppression, the Goths rose in arms, and spread desolation over the fertile plains of Thrace. Va'lens summoned his nephew, Gratian, to his assistance; but before the emperor of the west arrived, he imprudently engaged the Goths near Adrianople, and with the greater part of his army fell on[Pg. 370] the field. 19. This was the most disastrous defeat which the Romans had sustained for several centuries; and there was reason to dread that it would encourage a revolt of the Gothic slaves in the eastern provinces, which must terminate in the ruin of the empire. To prevent such a catastrophe, the senate of Constantinople ordered a general massacre of these helpless mortals, and their atrocious edict was put into immediate execution. 20. The Goths attempted to besiege both Adrianople and Constantinople, but, ignorant of the art of attacking fortified places, they were easily repelled; but they however succeeded in forcing their way through the Thracian mountains, and spread themselves over the provinces to the west, as far as the Adriatic sea and the confines of Italy. The march of the emperor Gratian had been delayed by the hostility of the Alleman'ni, whom he subdued in two bloody engagements; but as he advanced towards Adrianople, fame brought the news of his uncle's defeat and death, which he found himself unable to revenge.
21. Feeling that the affairs of the East required the direction of a mind more energetic than his own, he determined to invest with the imperial purple, Theodo'sius, the son of that general who had rescued Britain from the barbarians. How great must have been his confidence in the fidelity of his new associate, who had a father's death to revenge; for the elder Theodo'sius, notwithstanding his splendid services, had fallen a victim to the jealous suspicions of the emperor!
22. The reign of Theodo'sius in the East lasted nearly sixteen years, and was marked by a display of unusual vigour and ability. He broke the power of the Goths by many severe defeats, and disunited their leading tribes by crafty negociations. But the continued drain on the population, caused by the late destructive wars, compelled him to recruit his forces among the tribes of the barbarians, and a change was thus made in the character and discipline of the Roman army, which in a later age produced the most calamitous consequences. The exuberant zeal, which led him to persecute the Arians and the pagans, occasioned some terrible convulsions, which distracted the empire, and were not quelled without bloodshed. He, however, preserved the integrity of the empire, and not a province was lost during his administration.
23. The valour which Gratian had displayed in the early part of his life, rendered the indolence and luxury to which he abandoned himself, after the appointment of Theodo'sius,[Pg. 371] more glaring. The general discontent of the army induced Max'imus, the governor of Britain, to raise the standard of revolt, and, passing over to the continent, he was joined by the greater part of the Gallic legions. When this rebellion broke out Gratian was enjoying the sports of the field in the neighbourhood of Paris, and did not discover his danger until it was too late to escape. He attempted to save his life by flight, but was overtaken by the emissaries of the usurper, near Lyons, and assassinated. 24. Theodo'sius was induced to make peace with Max'imus, on condition that the latter should content himself with the prefecture of Gaul, and should not invade the territories of the younger Valentin'ian. 25. Ambition hurried the faithless usurper to his ruin; having by perfidy obtained possession of the passes of the Alps, he led an overwhelming army into Italy, and Valenti'nian, with his mother Justi'na, were scarcely able, by a hasty flight, to escape to the friendly court of Theodo'sius.
26. The emperor of the East readily embraced the cause of the fugitives; the numerous troops of barbarian cavalry which he had taken into pay, enabled him to proceed with a celerity which baffled all calculation. 27. Before Maximus could make any preparations for his reception, Theodosius had completely routed his army, and was already at the gates of Aquilei'a, where the usurper had taken refuge. The garrison, secretly disinclined to the cause of Maximus, made but a faint resistance, the town was taken, and the unfortunate ruler led as a captive into the presence of his conqueror, by whom he was delivered to the executioner.
Theodo'sius, having re-established the authority of the youthful Valentin'ian, returned home. But the emperor of the West did not long enjoy his restored throne; he was murdered by Arbogas'tes, his prime minister, who dreaded that the abilities displayed by the young prince would enable him, when arrived to maturity, to shake off the authority of an unprincipled servant. 28. The assassin was afraid himself to assume the purple, but he procured the election of Euge'nius, a man not wholly unworthy of empire. Theodo'sius was called by these events a second time to Italy; he passed the Alps, but found his further progress impeded by the judicious disposition which Arbogas'tes had made of his forces. Defeated in his first attack, Theodo'sius renewed the engagement on the following day, and being aided by the seasonable revolt of some Italian legions, obtained a[Pg. 372] complete victory. Euge'nius was taken prisoner, and put to death by the soldiers. Arbogas'tes, after wandering some time in the mountains, lost all hope of escape, and terminated his life by suicide.
