244. Honorius transferred his capital from Milan to the impregnable fortress among the marshes of Ravenna, which continued three centuries to be the seat of government for Italy. A fresh invasion from Germany, led by the pagan Radagai´sus, devastated western Italy. Gaul was, at the same time, overrun by a mingled horde of Vandals, Suevi, Alani, and Burgundians; and from that moment the Roman Empire may be said to have fallen in the countries beyond the Alps. The army in Britain revolted; and after electing and murdering two emperors, set up Constantine, who led them into Gaul, defeated the German invaders, passed into Spain, and established a kind of sovereignty over the three western countries of Europe.
Meanwhile, Stilicho was disgraced and slain, through the intrigues of his enemy, Olympius. While the barbarian auxiliaries in his army were lamenting his death, they were enraged by a massacre of their wives and children, who had been kept as hostages in the various cities of Italy. This insane act of cruelty sealed the fate of Rome. The barbarians, freed from either the duty or necessity of obeying Honorius, flocked to the camp of Alaric, in Illyricum, and urged him to invade Italy. The Visi-Goth had injuries of his own to avenge. He passed the Alps and the Po, and, after a rapid march, pitched his camp upon the Tiber. Rome was reduced to starvation. Thousands died of famine, and thousands more from the pestilence which it occasioned. At length, Alaric accepted the terms offered by the Senate, and retired, upon the payment of an enormous ransom, A. D. 408.
245. His brother-in-law, Adolphus, now joined him with a troop of Huns and Goths. Alaric offered peace to the court of Ravenna, on condition of receiving lands for his followers, between the Danube and the Adriatic. His demands being refused, he again marched upon Rome, and set up an emperor of his own choosing, in At´talus, præfect of the city. Ravenna was only saved from his attack by a reinforcement from Theodosius II., now emperor of the East. Africa was likewise delivered by the vigilance of Count Herac´lian. But Alaric was soon tired of his puppet-king. He deposed him, and again sought peace with Honorius. The treaty failed through the ill-will of Sarus, a Goth in the imperial service, who was a bitter enemy and rival of Alaric.
The king of the Visi-Goths now turned a third time, and with relentless rage, upon Rome. The Eternal City was taken, Aug. 10, A. D. 410, and for six days was given up to the horrible scenes of murder and pillage. Though greatly reduced in power, Rome had never lost her dignity, or the wealth of her old patrician houses. These were now ransacked; gold, jewels, and silken garments, Grecian sculptures and paintings, and the choicest spoils of conquered countries, brought home in triumph by ancestors of the present families, went to enrich the Gothic and Scythic hordes, who were so ignorant of the value of their plunder, that exquisite vases were often divided by a stroke of a battle-ax, and their fragments distributed among the common soldiers. Only the churches and their property were respected, for Alaric declared that he waged war with the Romans, and not with the apostles.
246. At length the king of the Goths withdrew, laden with spoils, along the Appian Way, meditating the conquest of Sicily and Africa. Storms, however, destroyed his hastily constructed fleet, and a sudden death terminated his career of conquest. He was buried in the channel of the little river Busenti´nus, and his sepulcher was adorned by his followers with the treasures of Rome. Adolphus, his successor, made peace with Honorius, and received the hand of the imperial princess Placid´ia, who had been taken prisoner during the siege. Her bridal gifts consisted of the spoils of her country. Adolphus retired into Gaul, and then into Spain, where he founded the kingdom of the Visi-Goths, as a dependency upon the Western empire.
Constantine was driven out of Spain, and captured at Arles, by Constantius, who was rewarded for his distinguished services by a marriage with Placidia, after the death of her Gothic husband, and by the imperial titles which he bore as the colleague of her brother. He reigned but seven months, and after his death Placidia quarreled with Honorius, and took refuge with her nephew at Constantinople. In a few months the emperor of the West ended a disgraceful reign of twenty-eight years, A. D. 423. John, his secretary, usurped the throne; but Theodosius II. sent a fleet and army to enforce the claims of his cousin, the son of Placidia, and the troops in Ravenna were easily persuaded to surrender their upstart emperor. John was beheaded at Aquileia, A. D. 425.
247. Valentinian III. was a child of six years. The Western empire was therefore placed under the regency of his mother, Placidia, who continued to rule it for a quarter of a century, while the military command was held by Aë´tius and Boniface. Unhappily, these two generals were enemies. The malicious falsehoods of Aëtius led Boniface into rebellion, and lost Africa to the empire. Gen´seric, king of the Vandals in Spain, willingly accepted the invitation of Boniface, and crossed the straits with 50,000 men. The Moors immediately joined his army; the Donatists[80] hailed him as their deliverer from persecution.
Too late, Boniface discovered his mistake, and returned to his allegiance. All Roman Africa, except Carthage, Cirta, and Hippo Regius, had passed over to the Vandals. Forces were sent from Constantinople to aid those of Italy; but the combined armies were defeated, and Boniface was compelled to abandon Africa, taking with him all the Roman inhabitants who were able to leave. The countries on the Danube had been ceded to the Eastern empire, in return for the aid of Theodosius II., in placing Valentinian III. upon his throne. Britain, unprotected by the Roman armies, had thrown off her allegiance, and had for forty years no government except that of the clergy, the nobles, and the magistrates of the towns. The Goths were settled permanently in south-western Gaul; the Burgundians in the east, and the Franks in the north of the same country; and except a small tract in southern Gaul, the Western empire now included only Italy and the region of the western Alps.
248. Aëtius defended the Gallic province against the Visi-Goths on one side, and the Franks on the other, until the latter called in a new and more terrible ally than all previous invaders, in At´tila, king of the Huns. This savage chief was known to the terror-stricken world of his time, as the Scourge of God. He had subdued to his authority all the barbarians between the Baltic and the Euxine, the Rhine and the Volga, and his army of 700,000 men was officered by a host of subject kings. He had been for nine years ravaging the Eastern empire to the very walls of Constantinople, and had only retired upon the promise of an enormous annual tribute, and the immediate payment of 6,000 pounds of gold. He now invaded Gaul, in behalf of a Frankish king who had been driven beyond the Rhine, and had sought his aid.
