Theod´oric, the son of Alaric, now king of the Visi-Goths, had allied himself with the Romans, and their united armies came up with Attila, just as he had effected the capture of Orleans by battering down its walls. The Hun instantly drew off his hordes from the plunder of the city, and retreated across the Seine to the plains about Chalons´, where his Scythian cavalry could operate to better advantage. Then followed one of the most memorable battles in the history of the world. The aged king Theodoric was slain, but the victory was gained by the valor of his subjects. Attila was driven to his circle of wagons, and only the darkness of night prevented the total destruction of his hosts.
This was the last victory ever achieved in the name of the Western empire. It settled the great question, whether modern Europe should be Teuton or Tartar. The Goths were already Christian; their rude energy was well adapted to the laws and institutions of civilized life. The Huns were savage, heathen, destructive; mighty to ravage and desolate, but never, in their greatest power and wealth, known to build and organize a state. Most of what is admirable in European history would have been reversed by a different result of the battle of Chalons.
249. Attila retreated beyond the Rhine. Two years later, he descended into north-eastern Italy, reduced Aquileia, Alti´num, Concordia, and Padua to heaps of ashes, and plundered Pavia and Milan. The fugitives from the old territory of the Veneti took refuge upon the hundred low islets at the head of the Adriatic, and laid, in poverty and industry, the foundations of the Republic of Venice. While he was diverted from his threatened march upon Rome, by the intercessions of Pope Leo, Attila suddenly died, and his kingdom fell to pieces even more rapidly than it had been built up. Two of his sons perished in battle. Irnac, the youngest, retired into Scythia. Valentinian showed his relief from apprehension by murdering Aëtius with his own hand. Having in many ways disgusted and offended his subjects, he was himself assassinated in March, A. D. 455.
Maximus, his murderer, assumed the purple, but he continued in power less than three months. Eudox´ia, the widow of Valentinian, called in the aid of Genseric, the Vandal king of Africa, who, commanding the Mediterranean with his fleets, was only too eager for the spoils of Italy. The Romans, as soon as he had landed in Ostia, put to death their unworthy emperor; but this execution failed to appease the barbarian. Fourteen days the Eternal City was again given up to a pillage more unscrupulous than that of Alaric. The Vandal fleet, waiting at Ostia, was laden with all the wealth which the Goths had spared, and receiving on board the empress Eudoxia and her daughter, made a safe return to Carthage.
250. The Romans were too much paralyzed to appoint a new sovereign. When the news reached Gaul, Avi´tus, the general of the armies there, was proclaimed, through the influence of Theodoric II., and was acknowledged for more than a year throughout the Western empire. But, A. D. 456, Count Ric´imer, a Goth commanding the foreign auxiliaries in Italy, rebelled, and captured Avitus in a battle near Placentia. He set up Marjo´rian, whose talents and virtues revived some appearance of justice and energy in the government. A fleet was now prepared for the invasion of Africa, in the hope not only of retaliating upon Genseric for his plunder of Rome, but of stopping the ravages of the Vandal pirates upon the coasts of Italy. It was betrayed to the emissaries of Genseric, in the Spanish port of Carthagena.
Ricimer, by this time, was jealous of his protégé, and, forcing him to resign, set up a new puppet in the person of Lib´ius Severus, in whose name he hoped to exercise the real power. But the nominal rule of Severus was confined to Italy, while, beyond the Alps, two Roman generals—Marcellinus in Dalmatia, and Ægid´ius in Gaul—possessed the real sovereignty, though without the imperial titles. The coasts of Italy, Spain, and Greece were continually harassed by the Vandals, and Ricimer, two years after the death of Severus (A. D. 467), appealed to the court of Constantinople for aid against the common enemy, promising to accept any sovereign whom the emperor would appoint.
251. Anthe´mius, a Byzantine nobleman, was designated as emperor of the West, and received the allegiance of the Senate, the people, and the barbarian troops. The fidelity of Count Ricimer was thought to be secured by his marriage with the daughter of the new emperor. A formidable attack upon the Vandals was made by the combined forces of the East and the West; but it failed through the weakness or treachery of Bas´ilis´cus, the Greek commander, who lost his immense fleet through the secret management of Genseric. The Vandals recovered Sardinia and became possessed of Sicily, whence they could ravage Italy more constantly than ever.
The Goths, meanwhile, became dissatisfied with the foreign rule. Ricimer retired to Milan, where, in concert with his people, he openly revolted, marched with a Burgundian army to Rome, and forced the Senate to accept a new emperor in the person of Olyb´rius, A. D. 472. Anthemius was slain in the attack upon the city. Ricimer died forty days after his victory, bequeathing his power to his nephew, Gund´obald, a Burgundian. Olybrius died a month or two later, and Gundobald raised a soldier named Glyce´rius to the vacant throne. The emperor of the East interfered again, and appointed Julius Nepos—a nephew of Marcellinus of Dalmatia—who was accepted by the Romans and Gauls, Glycerius being consoled for the loss of his imperial titles by the safer and more peaceful dignity of Bishop of Salo´na.
252. Scarcely was Julius invested with the insignia of his rank, when he was driven from the country by a new sedition led by Ores´tes, master-general of the armies, who placed upon the throne his own son, Romulus Augustus. This last of the Western emperors, who bore, by a curious coincidence, the names of the two founders of Rome and the empire, was more commonly called Augus´tulus, in burlesque of the imperial grandeur which mocked his youth and insignificance.
