The general tenor of his reign was peaceful; and we may conclude therefore that he was of an unwarlike temper, since the circumstances of the time were such as would naturally have induced a prince of any military capacity to resume hostilities against the Romans.

After the arrangement made with Rome by Sapor III.
in A.D.384, a terrible series of calamities had befallen the empire.
Invasions of Ostrogoths and Franks signalized the years A.D.386 and 388; in A.D.387 the revolt of Maximus seriously endangered the western moiety of the Roman state; in the same year occurred an outburst of sedition at Antioch, which was followed shortly by the more dangerous sedition, and the terrible massacre of Thessalonica; Argobastes and Eugenius headed a rebellion in A.D.

393; Gildo the Moor detached Africa from the empire in A.D.386, and maintained a separate dominion on the southern shores of the Mediterranean for twelve years, from A.D.

386 to 398; in A.D.395 the Gothic warriors within and without the Roman frontier took arms, and under the redoubtable Alaric threatened at once the East and the West, ravaged Greece, captured Corinth, Argos, and Sparta, and from the coasts of the Adriatic already marked for their prey the smiling fields of Italy.

The rulers of the East and West, Arcadius and Honorius, were alike weak and unenterprising; and further, they were not even on good terms, nor was either likely to trouble himself very greatly about attacks upon the territories of the other.
Isdigerd might have crossed the Euphrates, and overrun or conquered the Asiatic provinces of the Eastern Empire, without causing Honorious a pang, or inducing him to stir from Milan.
