At this time Theodosius, son of Arcadius, succeeded to the empire; and, bestowing little attention on the affairs of the west, caused those who had taken possession to think of securing their acquisitions.  Thus the Vandals ruled Africa; the Alans and Visigoths, Spain; while the Franks and Burgundians not only took Gaul, but each gave their name to the part they occupied; hence one is called France, the other Burgundy.  The good fortune of these brought fresh people to the destruction of the empire, one of which, the Huns, occupied the province of Pannonia, situated upon the nearer shore of the Danube, and which, from their name, is still called Hungary.  To these disorders it must be added, that the emperor, seeing himself attacked on so many sides, to lessen the number of his enemies, began to treat first with the Vandals, then with the Franks; a course which diminished his own power, and increased that of the barbarians.  Nor was the island of Britain, which is now called England, secure from them; for the Britons, being apprehensive of those who had occupied Gaul, called the Angli, a people of Germany, to their aid; and these under Vortigern their king, first defended, and then drove them from the island, of which they took possession, and after themselves named the country England.  But the inhabitants, being robbed of their home, became desperate by necessity and resolved to take possession of some other country, although they had been unable to defend their own.  They therefore crossed the sea with their families, and settled in the country nearest to the beach, which from themselves is called Brittany.  The Huns, who were said above to have occupied Pannonia, joining with other nations, as the Zepidi, Eurili, Turingi, and Ostro, or eastern Goths, moved in search of new countries, and not being able to enter France, which was defended by the forces of the barbarians, came into Italy under Attila their king.  He, a short time previously, in order to possess the entire monarchy, had murdered his brother Bleda; and having thus become very powerful, Andaric, king of the Zepidi, and Velamir, king of the Ostrogoths, became subject to him.  Attila, having entered Italy, laid siege to Aquileia, where he remained without any obstacle for two years, wasting the country round, and dispersing the inhabitants.  This, as will be related in its place, caused the origin of Venice.  After the taking and ruin of Aquileia, he directed his course towards Rome, from the destruction of which he abstained at the entreaty of the pontiff, his respect for whom was so great that he left Italy and retired into Austria, where he died.  After the death of Attila, Velamir, king of the Ostrogoths, and the heads of the other nations, took arms against his sons Henry and Uric, slew the one and compelled the other, with his Huns, to repass the Danube and return to their country; while the Ostrogoths and the Zepidi established themselves in Pannonia, and the Eruli and the Turingi upon the farther bank of the Danube.
