Then came the fourth century and the terrible visitation of the Huns, those mysterious Asiatic horsemen who for more than two centuries maintained themselves in Northern Europe and continued their career of bloodshed until they were defeated near Chalons-sur-Marne in France in the year 451. As soon as the Huns had reached the Danube they had begun to press hard upon the Goths. The Goths, in order to save themselves, were thereupon obliged to invade Rome. The Emperor Valens tried to stop them, but was killed near Adrianople in the year 378. Twenty-two years later, under their king, Alaric, these same West Goths marched westward and attacked Rome. They did not plunder, and destroyed only a few palaces. Next came the Vandals, and showed less respect for the venerable traditions of the city. Then the Burgundians. Then the East Goths. Then the Alemanni. Then the Franks. There was no end to the invasions. Rome at last was at the mercy of every ambitious highway robber who could gather a few followers. In the year 402 the Emperor fled to Ravenna, which was a sea-port and strongly fortified, and there, in the year 475, Odoacer, commander of a regiment of the German mercenaries, who wanted the farms of Italy to be divided among themselves, gently but effectively pushed Romulus Augustulus, the last of the emperors who ruled the western division, from his throne, and proclaimed himself Patriarch or ruler of Rome. The eastern Emperor, who was very busy with his own affairs, recognised him, and for ten years Odoacer ruled what was left of the western provinces. A few years later, Theodoric, King of the East Goths, invaded the newly formed Patriciat, took Ravenna, murdered Odoacer at his own dinner table, and established a Gothic Kingdom amidst the ruins of the western part of the Empire. This Patriciate state did not last long. In the sixth century a motley crowd of Longobards and Saxons and Slavs and Avars invaded Italy, destroyed the Gothic kingdom, and established a new state of which Pavia became the capital. Then at last the imperial city sank into a state of utter neglect and despair. The ancient palaces had been plundered time and again. The schools had been burned down. The teachers had been starved to death. The rich people had been thrown out of their villas which were now inhabited by evil-smelling and hairy barbarians. The roads had fallen into decay. The old bridges were gone and commerce had come to a standstill. Civilisation--the product of thousands of years of patient labor on the part of Egyptians and Babylonians and Greeks and Romans, which had lifted man high above the most daring dreams of his earliest ancestors, threatened to perish from the western continent.
