Mohammed conquered the Meccans mainly by paralysing their caravan trade. When, in the eighth year after his departure from his native town, he made his triumphal entry into it once more, it needed only one great encounter with certain Bedouin tribes to bring the whole of Arabia to his feet and to his faith. If the Bedouins had concluded binding alliances against him in defence of the religious usages of their forefathers and (what was still more important to them) their own independence, he would have laboured in vain; but the inability of the pure Arab to unite for common action and act under discipline, even for the attainment of great ends, made it possible for him to bring one tribe after another over to his side by force or friendly means. He even contrived to turn to practical account the old connection between his family and the tent-dwelling Choza’a in the neighbourhood of Mecca. He retained old customs wherever it was possible so to do, instinctively rather than by deliberate intention. Thus even the greater part of the heathen worship of Mecca was adapted in externals to monotheism and incorporated _bona fide_ into Islam. The first important successes, especially the battle of Bedr (a great battle according to Arab notions), in which the men of Mecca lost about seventy dead and seventy wounded, made a deep and immediate impression: success is the test of proselytisers. The costly presents which Mohammed gave out of his spoils to such distinguished men as had not at once become converts at heart also wrought effectively; in most cases a genuine conversion followed in time. One fact (among others), by which we can estimate the striking impression the prophet produced upon the Arabs, is that as each tribe submitted or adopted his religion it renounced the right of retaliation for the blood shed in the struggle. Under other circumstances this renunciation of blood-revenge, or of wergild at least, would have seemed to the Arab the lowest depth of humiliation. But hard as it might be for the Arabs in general to acknowledge the prophet as their lord, there was at that time no pagan who would have fought in earnest for his religion. At the utmost, an old woman here and there raised a clamour when Mohammed destroyed her idols. Compare this with the fashion in which other Semites fought for their faith, in which the Arabs themselves afterwards fought for Islam. Hence, it is evident that, as has been said, the Arabs of that period had outgrown their religion. SUCCESSORS OF MOHAMMED
