Tradition says that these monsters, mounted on their shaggy ponies, rode women and children under foot and feasted on human flesh. Whether this be true or no, their name became a terror to the civilized world, and after a few encounters with them the Visigoths crowded on the edge of the Danube and implored the Emperor to allow them to shelter behind the line of Roman forts.

Valens, to whom the petition was made, hesitated. There was obvious danger to his dominions in this sudden influx of a whole tribe; but on the other hand fear might madden the Visigoths into trying to cross even if he refused, and if so could he withstand them?

‘All the multitude that had escaped from the murderous savagery of the Huns,’ says a writer of the day, ‘no less than 200,000 fighting men besides women and old men and children, were there on the river bank, stretching out their hands with loud lamentations ... and promising that they would ever faithfully adhere to the imperial alliance, if only the boon was granted them.’

Reluctantly Valens yielded; and soon the province of Dacia was crowded with refugees; but here the real trouble began. Food must be found for this multitude, and it was evident that the local crops would not suffice. In vain the Emperor commanded that corn should be imported: the greed of officials who were responsible for carrying out this order led them to hold up large consignments, and to sell what little they allowed to pass at wholly extortionate rates. Their unwelcome guests, half-starved and fleeced of the small savings they had been able to bring with them, complained, plotted, and broke at last into open rebellion.

This treatment of the Visigoths in Dacia is one of the worst pages in the history of the Roman Empire, but it brought its own speedy punishment. The suspicion and hatred engendered by misery spread like a flame, and the barbarian forces were joined by deserters of their own race from the imperial legions and by runaway slaves until they had grown into a formidable army. Valens, forced to take steps to preserve his throne, met them on the battle-field of Adrianople, but only to suffer crushing defeat. He himself was slain, and some 40,000 of those who had served under his banner.

The Emperor Theodosius

Never before had the imperial eagles met with such a reverse at barbarian hands, and the Visigoths after the first moment of triumph were almost alarmed at the extent of their own success. Before the frowning walls of Constantinople their courage faltered, and without attempting a siege they retreated northwards into Thrace. Gladly they came to terms with Theodosius, Valens’s successor, who, not content with regranting them the lands to the south of the Danube that they so much desired, increased his army by taking whole regiments of their best warriors into his pay.

‘Lover of peace and of the Goths’ is the character with which Theodosius has passed down to posterity, and during his reign the Visigoths and other northern tribes received continual marks of his favour.

One of the Gothic kings, the old chief Athanaric, went to visit him at Constantinople, and was overwhelmed by the magnificence and luxury he saw around him. ‘Now do I at last behold,’ he exclaimed, ‘what I have often heard but deemed incredible.... Doubtless the Emperor is a God on earth, and he who raises a hand against him is guilty of his own blood.’

The alliance between Goth and Greek served its purpose at the moment, for by the aid of his new troops Theodosius was able to defeat the rival Emperor of Rome and to conquer Italy. When he died he left Constantinople and the East to his eldest son Arcadius, a youth of eighteen, and Rome and the West to the younger, Honorius, who was only eleven. True to his belief in barbarian ability, Theodosius selected a Vandal chief, Stilicho, to whom he had given his niece in marriage, that he might act as the boy’s adviser and command the imperial forces.
