About the year A.D. 372 the Huns, an enormous Tartar horde from beyond the Don and Volga, burst into the lands north of the Euxine, and began to work their way westward. The first tribe that lay in their way, the nomadic race of the Alans, they almost exterminated. Then they fell upon the Goths. The Ostrogoths made a desperate attempt to defend the line of the Dniester against the oncoming savages—“men with faces that can hardly be called faces—rather shapeless black collops of flesh with little points instead of eyes; little in stature, but lithe and active, skilful in riding, broad shouldered, good at the bow, stiff-necked and proud, hiding under a barely human form the ferocity of the wild beast.” But the enemy whom the Gothic historian describes in these uninviting terms was too strong for the Teutons of the East. The Ostrogoths were crushed and compelled to become vassals of the Huns, save a remnant who fought their way southward to the Wallachian shore, near the marshes of the Delta of the Danube. Then the Huns fell on the Visigoths. The wave of invasion pressed on; the Bug and the Pruth proved no barrier to the swarms of nomad bowmen, and the Visigoths, under their Duke Fritigern, fell back in dismay with their wives and children, their waggons and flocks and herds, till they found themselves with their backs to the Danube. Surrender to the enemy was more dreadful to the Visigoths than to their eastern brethren; they were more civilized, most of them were Christians, and the prospect of slavery to savages seems to have appeared intolerable to them. Pressed against the Danube and the Roman border, the Visigoths sent in despair to ask permission to cross from the Emperor. A contemporary writer describes how they stood. “All the multitude that had escaped from the murderous savagery of the Huns—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 earnestly supplicating leave to cross, bewailing their calamity, and promising that they would ever faithfully adhere to the imperial alliance if only the boon was granted them.” At this moment (A.D. 376) the Roman Empire was again divided. The house of Constantine was gone, and the East was ruled by Valens, a stupid, cowardly, and avaricious prince, who had obtained the diadem and half the Roman world only because he was the brother of Valentinian, the greatest general of the day. Valentinian had taken the West for his portion, and dwelt in his camp on the Rhine and Upper Danube, while Valens, slothful and timid, shut himself up with a court of slaves and flatterers in the imperial palace at Constantinople.
