In order to appreciate the life and actions of Belisarius, it is necessary to understand the character of the new emperor, during whose long reign his great exploits were performed. The first act of Justinian on ascending the throne, was to marry a dissolute actress, named Theodora, who, though licentious, avaricious, cruel and vindictive, soon acquired an almost complete control over him. His mind was essentially feeble and inconstant, and, though his Christian faith was doubtless sincere, it was less fruitful of virtues than of rites and forms. At his accession his treasury was full; but it was soon exhausted by his profuseness, and heavy taxes were imposed, offices put to sale, charities suppressed, private fortunes seized, and, in short, every act of rapacity, injustice and oppression, practised by his ministers, to support the wasteful magnificence of the court. The troops of the empire at this period were by no means what they had been in the time of Scipio and Cæsar. They consisted, to a great extent, of foreign mercenaries, and were divided into squadrons according to their country; thus destroying all unity of feeling, and annihilating that national spirit which once made the Roman arms the terror of the world. These hired troops, which greatly outnumbered the native soldiers, marched under their own national banner, were commanded by their own officers, and usually followed their own military regulations. The inefficiency of such mingled and discordant forces, is obvious; yet it was under such a system that Belisarius entered upon his military career. With a feeble and corrupt government, an ill-appointed and trustless army, the Roman empire was still surrounded with powerful enemies. It is scarcely possible to conceive of a great nation in a condition of more complete debility and helplessness, than was the kingdom of the Cæsars, at the period in which Belisarius appears upon the active stage of life. Kobad, king of Persia, after a long cessation of hostilities, renewed the war toward the close of Justin’s reign, by the invasion of Iberia, which claimed the protection of the emperor. At this period, Belisarius, being about twenty years of age, had the command of a squadron of horse, and was engaged in some of the conflicts with the Persian forces, on the borders of Armenia. In conjunction with an officer named Sittas, he ravaged a large extent of territory, and brought back a considerable number of prisoners. On a second incursion, however, they were less fortunate; for, being suddenly attacked by the Persian forces, they were entirely defeated. It appears that Belisarius incurred no blame, for he was soon after promoted to the post of governor of Dara, and the command of the forces stationed there. It was at this place that he chose Procopius, the historian, as his secretary, and who afterwards repaid his kindness by a vain attempt to brand his name with enduring infamy.
