The misfortunes which befell the western empire caused the emperor, who resided at Constantinople, on many occasions to give up the possession of it to others, as a charge full of danger and expense; and sometimes, without his permission, the Romans, seeing themselves so abandoned, created an emperor for their defense, or suffered some one to usurp the dominion.

This occurred at the period of which we now speak, when Maximus, a Roman, after the death of Valentinian, seized the government, and compelled Eudocia, widow of the late emperor, to take him for her husband; but she, being of imperial blood, scorned the connection of a private citizen; and being anxious to avenge herself for the insult, secretly persuaded Genseric, king of the Vandals and master of Africa to come to Italy, representing to him the advantage he would derive from the undertaking, and the facility with which it might be accomplished.

Tempted by the hope of booty, he came immediately, and finding Rome abandoned, plundered the city during fourteen days.

He also ravaged many other places in Italy, and then, loaded with wealth, withdrew to Africa.

The Romans, having returned to their city, and Maximus being dead, elected Avitus, a Roman, as his successor.
