flight of the Huns, by the victorious Sienpi, who were sometimes broken into independent tribes, and sometimes reunited under a supreme chief; till at length, styling themselves Topa, or masters of the earth, they acquired a more solid consistence, and a more formidable power. The Topa soon compelled the pastoral nations of the eastern desert to acknowledge the superiority of their arms; they invaded China in a period of weakness and intestine discord; and these fortunate Tartars, adopting the laws and manners of the vanquished people, founded an Imperial dynasty, which reigned near one hundred and sixty years over the northern provinces of the monarchy. Some generations before they ascended the throne of China, one of the Topa princes had enlisted in his cavalry a slave of the name of Moko, renowned for his valor, but who was tempted, by the fear of punishment, to desert his standard, and to range the desert at the head of a hundred followers. This gang of robbers and outlaws swelled into a camp, a tribe, a numerous people, distinguished by the appellation of Geougen; and their hereditary chieftains, the posterity of Moko the slave, assumed their rank among the Scythian monarchs. The youth of Toulun, the greatest of his descendants, was exercised by those misfortunes which are the school of heroes. He bravely struggled with adversity, broke the imperious yoke of the Topa, and became the legislator of his nation, and the conqueror of Tartary. His troops were distributed into regular bands of a hundred and of a thousand men; cowards were stoned to death; the most splendid honors were proposed as the reward of valor; and Toulun, who had knowledge enough to despise the learning of China, adopted only such arts and institutions as were favorable to the military spirit of his government. His tents, which he removed in the winter season to a more southern latitude, were pitched, during the summer, on the fruitful banks of the Selinga. His conquests stretched from Corea far beyond the River Irtish. He vanquished, in the country to the north of the Caspian Sea, the nation of the Huns; and the new title of Khan, or Cagan, expressed the fame and power which he derived from this memorable victory.

The chain of events is interrupted, or rather is concealed, as it passes from the Volga to the Vistula, through the dark interval which separates the extreme limits of the Chinese, and of the Roman, geography. Yet the temper of the Barbarians, and the experience of successive emigrations, sufficiently declare, that the Huns, who were oppressed by the arms of the Geougen, soon withdrew from the presence of an insulting victor. The countries towards the Euxine were already occupied by their kindred tribes; and their hasty flight, which they soon converted into a bold attack, would more naturally be directed towards the rich and level plains, through which the Vistula gently flows into the Baltic Sea. The North must again have been alarmed, and agitated, by the invasion of the Huns; * and the nations who retreated before them must have pressed with incumbent weight on the confines of Germany. The inhabitants of those regions, which the ancients have assigned to the Suevi, the Vandals, and the Burgundians, might embrace the resolution of abandoning to the fugitives of Sarmatia their woods and morasses; or at least of discharging their superfluous numbers on the provinces of the Roman empire. About four years after the victorious Toulun had assumed the title of Khan of the Geougen, another Barbarian, the haughty Rhodogast, or Radagaisus, marched from the northern extremities of Germany almost to the gates of Rome, and left the remains of his army to achieve the destruction of the West. The Vandals, the Suevi, and the Burgundians, formed the strength of this mighty host; but the Alani, who had found a hospitable reception in their new seats, added their active cavalry to the heavy infantry of the Germans; and the Gothic adventurers crowded so eagerly to the standard of Radagaisus, that by some historians, he has been styled the King of the Goths. Twelve thousand warriors, distinguished above the vulgar by their noble birth, or their valiant deeds, glittered in the van; and the whole multitude, which was not less than two hundred thousand fighting men, might be increased, by the accession of women, of children, and of slaves, to the amount of four hundred thousand persons. This formidable emigration issued from the same coast of the Baltic, which had poured forth the myriads of the Cimbri and Teutones, to assault Rome and Italy in the vigor of the republic. After the departure of those Barbarians, their native country, which was marked by the vestiges of their greatness, long ramparts, and gigantic moles, remained, during some ages, a vast and dreary solitude; till the human species was renewed by the powers of generation, and the vacancy was filled by the influx of new inhabitants. The nations who now usurp an extent of land which they are unable to cultivate, would soon be assisted by the industrious poverty of their neighbors, if the government of Europe did not protect the claims of dominion and property.
