The Historians' History of the World 07 [The History of the Later Roman Empire]

BARRIERS AGAINST THE NORTHERN BARBARIANS

Heraclius appears to have formed the plan of establishing a permanent barrier in Europe against the encroachments of the Avars and Slavonians. For the furtherance of this project, it was evident that he could derive no assistance from the inhabitants of the provinces to the south of the Danube. The imperial armies, too, which in the time of Maurice had waged an active war in Illyricum and Thrace and frequently invaded the territories of the Avars, had melted away during the disorders of the reign of Phocas. The loss was irreparable; for in Europe no agricultural population remained to supply the recruits required to form a new army.

The only feasible plan for circumscribing the ravages of the northern enemies of the empire which presented itself, was the establishment of powerful colonies of tribes hostile to the Avars and their eastern Slavonian allies, in the deserted provinces of Dalmatia and Illyricum. To accomplish this object Heraclius induced the Serbs, or western Slavonians, who occupied the country about the Carpathian Mountains and who had successfully opposed the extension of the Avar empire in that direction, to abandon their ancient seats, and move down to the south into the provinces between the Adriatic and the Danube. The Roman and Greek population of these provinces had been driven towards the sea coast by the continual incursions of the northern tribes, and the desolate plains of the interior had been occupied by a few Slavonian subjects and vassals of the Avars. The most important of the western Slavonian tribes who moved southward at the invitation of Heraclius were the Servians and Croatians, who settled in the countries still peopled by their descendants. Their original settlements were formed in consequence of friendly arrangements, and, doubtless, under the sanction of an express treaty; for the Slavonian people of Illyricum and Dalmatia long regarded themselves as bound to pay a certain degree of territorial allegiance to the Eastern Empire.

A Saracen

The measures of Heraclius were carried into execution with skill and vigour. From the borders of Istria to the territory of Dyrrhachium, the whole country was occupied by a variety of tribes of Servian or western Slavonic origin, hostile to the Avars. These colonies, unlike the earlier invaders of the empire, were composed of agricultural communities; and to the facility which this circumstance afforded them of adopting into their political system any remnant of the old Slavonic population of their conquests, it seems just to attribute the permanency and prosperity of their settlements. Unlike the military races of Goths, Huns, and Avars, who had preceded them, the Servian nations increased and flourished in the lands which they had colonised; and by the absorption of every relic of the ancient population, they formed political communities and independent states, which offered a firm barrier to the Avars and other hostile nations.

The fame of Heraclius would have rivalled that of Alexander, Hannibal, or Cæsar, had he expired at Jerusalem, after the successful termination of the Persian War. He had established peace throughout the empire, restored the strength of the Roman government, revived the power of Christianity in the East, and replanted the holy cross on Mount Calvary. His glory admitted of no addition. Unfortunately, the succeeding years of his reign have, in the general opinion, tarnished his fame. Yet these years were devoted to many arduous labours; and it is to the wisdom with which he restored the strength of his government during this time of peace that we must attribute the energy of the Asiatic Greeks who arrested the great tide of Mohammedan conquest at the foot of Mount Taurus. Though the military glory of Heraclius was obscured by the brilliant victories of the Saracens, still his civil administration ought to receive its meed of praise, when we compare the resistance made by the empire which he reorganised with the facility which the followers of Mohammed found in extending their conquests over every other land from India to Spain.

RELIGIOUS ACTIVITIES OF HERACLIUS

The policy of Heraclius was directed to the establishment of a bond of union, which should connect all the provinces of his empire into one body, and he hoped to replace the want of national unity by identity of religious belief. The church was far more closely connected with the people than any other institution, and the emperor, as political head of the church, hoped to direct a well-organised body of churchmen. But Heraclius engaged in the impracticable task of imposing a rule of faith on his subjects, without assuming the office, or claiming the authority of a prophet or a saint. His measures, consequently, like all ecclesiastical and religious reforms which are adopted solely from political motives, only produced additional discussions and difficulties. In the year 630, he propounded the doctrine that in Christ, after the union of the two natures, there was but one will and one operation. Without gaining over any great body of the schismatics whom he wished to restore to the communion of the established church by his new rule of faith, he was himself generally stigmatised as a heretic. The epithet Monothelite was applied to him and to his doctrine, to show that neither was orthodox.
