MOSLEM CONQUESTS
Arabia was hardly reconquered before the great invasion of other countries began. The prophet himself had set on foot some enterprises against Syria, but without any particular result. The great thing now to be accomplished was to transform the Arab hordes from recalcitrant subjects into joyful warriors of God by the twofold prospect of earthly spoil and heavenly rewards. Here we recognise the hand of Omar, to whom the sovereignty passed directly on the death of Abu-Bekr soon after. The wars of conquest which he inaugurated were crowned with brilliant success. It is worth while to consider the subject briefly in detail.
Troublesome enemies as the Arab tribes had often proved to the subjects of the Roman and Persian empires, no one had ever dreamed that they could constitute a menace to either. It is true that when the Moslem inroads began, the districts first affected were in a sorry plight. The frequent wars between the Romans and Persians had sorely enfeebled both empires, and this was more particularly the case with the last great war, which had lasted from 607 to 628. Large areas of Roman territory, especially in Palestine, Syria, and Egypt, had been frightfully ravaged and occupied for years by the Persians. The valiant and wily emperor Heraclius, however, succeeded in turning the tide of fortune, and ultimately dictated terms of peace to the Persians on their own soil. After that the Persian empire had been torn asunder by quarrels over the succession. Both empires had lost the Arab outpost they once possessed. The Persians had annihilated the Roman vassal kingdom of the Ghassanids, and their own subject dynasty in Hira (which had latterly adopted the Christian faith) had been dethroned by King Chosroes II. The folly of this was soon apparent. The Bedouins of the Shaiban tribe utterly routed the royal armies of Persia at Ibu Kar on the frontiers of Babylonia, probably at the very time when the king’s forces were pursuing their victorious progress through the distant west. It was not a great battle, and probably its only direct consequence was that the unwarlike peasants of neighbouring districts were pillaged by the Bedouins; but a victory over an army composed in part of regular troops gave the Arabs confidence. This very Shaiban tribe distinguished itself in the first Moslem advance into Persian territory.
Nevertheless there is much that remains enigmatical in the immense success that attended the Moslems. Their armies were not very large. The emperor Heraclius was an able man, with all the prestige of victory behind him. When the great struggle of Moslem and Persian began, the civil wars of the empire were over, and it had a powerful leader—not indeed in Yezdegerd, its youthful monarch, but in the mighty prince Rustem, who had procured the crown for him. The great financial straits to which both empires were unquestionably reduced must have had its effect upon the number and efficiency of their troops, but that they were still good for something is clear from the fact that both the decisive battle on the river Yarmuk (August, 636) in which the Romans were defeated, and that of Kadisiya (end of 636 or beginning of 637) in which a like fate waited on the Persian arms, lasted for several days. The resistance offered must have been very obstinate. The Roman and Persian armies may have included irregular troops of various kinds, but they certainly consisted largely of disciplined soldiers under experienced officers. The Persians brought elephants into the field, as well as their dreaded mounted cuirassiers. Among the Arabs there was no purely military order of battle; they fought in the order of their clans and tribes. This, though it probably insured a strong feeling of comradeship, was by no means an adequate equivalent for regular military units. Freiherr von Kremer[20] rightly sees in the salat a substitute, to some extent, for military drill. In that ceremony the Arabs, hitherto wholly unaccustomed to discipline, were obliged en masse to repeat the formulæ with strict exactitude after their leader and to copy every one of his movements, and any man who was unable to perform the salat with the congregation was none the less bound to strict compliance with the form of prayer in which he had been instructed. But the main factor was the powerful corporate feeling of the Moslem, the ever increasing enthusiasm for the faith even in those who had at first been indifferent, and the firm conviction that the warriors for the holy cause, though death in the field would prevent them from taking a share in the spoils of victory on earth, would yet partake of the most delightful of terrestrial joys in heaven. Thus the masterless Arabs, who, for all their turn for boasting, had but little stomach for heroic deeds, were transformed into the irresistible warriors of Allah. It was the highest triumph of Semitic religious zeal, a manifestation on a vast scale that among the Arabs the sense of religion had only slumbered, to awaken when occasion arose with true Semitic fury. The same thing has since come to pass again and again on a smaller scale.
For the rest, so far as we can tell, the Arab tribes were not all alike concerned in these wars of conquest. The great camel-breeding tribes of the highlands of the interior, in particular, seem to have taken a much smaller share in them than the tribes of the northern districts of Yemen. It was a point of the utmost importance that the supreme command was almost throughout in the hands of men of the Koreish, who at that time proved themselves a race of born rulers. They led Islam from victory to victory, proving themselves good Moslems on the whole, but without renouncing their worldly wisdom. Above all we are constrained to admire the skill, caution, and boldness with which, from his headquarters at Medina, Omar directed the campaigns and the rudiments of reorganisation in conquered countries.
This unpolished and rigidly orthodox man, who lived with the utmost Arab simplicity while an incalculable revenue was flowing into the treasury of the empire, proved one of the greatest and wisest of sovereigns. His injunction that the Arabs should acquire no landed property in the conquered countries, but should everywhere constitute a military caste in the pay of the state, was grandly conceived, but proved impracticable in the long run. Some of the Christian Arabs at first fought against the Moslem, but without any very great zeal. The majority of them soon exchanged a Christianity that had never gone very deep for the national religion. The great tribe of the Taghlib in the Mesopotamian desert was almost the only one in which Christianity retained its ascendency for any length of time, but it nevertheless fully participated in the fortunes of the Moslem empire, and even there the older faith gradually passed away, as it seems to have done among all Arabs of pure blood.
The victories of the Moslems under Omar were continued under his successor Othman. Syria, Mesopotamia, Babylonia,[21] Assyria, the greater part of Iran proper, Egypt, and some more of the northern parts of Africa were already conquered. The inhabitants of the Roman provinces had almost everywhere submitted to the conquerors without a struggle; in some cases they had even made overtures to them. The deplorable Christological disputes contributed largely to this result: the bulk of the Syrians and Copts were Monophysites and were consequently persecuted in many ways by the adherents of the Council of Chalcedon, who had gained the ascendency at Constantinople. Moreover in other respects the Roman government of the period was not qualified to inspire its Semitic and Egyptian subjects with any great devotion. The rule of the Arabs, though severe, at first was just, and above all they scrupulously observed all treaties whatsoever concluded with them. And the inhabitants of those countries were accustomed to subjection. It is, however, unlikely that they did the victors much positive service beyond occasionally acting as spies, and we must not lay too much stress upon the subjugation of what was on the whole an unwarlike race. Even in Iran, where Islam was confronted by far stronger opposition on national and religious grounds, the bulk of the population, especially in rural districts, offered at most a desultory resistance, while the victors had still many a battle to fight with the forces of the king and the nobles.
