In the meantime, however, the Arabs who had entered into closer relations with the Roman Empire, and the majority of those who occupied a like position towards Persia, had adopted at least a superficial form of Christianity. There were also some Christians in the interior of Arabia, while in the south Christianity had long since gained a considerable following. It had been persecuted for a while by a Jewish ruler; it was ultimately delivered by the Abyssinian conquest, but had made small progress since then. Christianity as practised by the Syrians, or, worse still, the Abyssinians, was not well adapted to win proselytes among the Arabs. If only the disciplined strength of Rome had acted upon these regions the case would probably have been different. There were Jews here and there in Arabia, and like the Jews of Abyssinia most of them seem not to have been genuine children of Israel, but native converts to Judaism. The Arab Jews, though possessed of no great theological knowledge, adhered strictly to their religion. The majority of Arabs was composed of heathen who had outgrown their religion. There were probably men who were conscious of the defects of this state of things, and recognised that the Christians had in many points an advantage over the heathen. We are told of certain persons from Mecca and its vicinity who adopted, and even preached, a monotheistic faith more or less Christian, but the details are very obscure. Certainly at the beginning of the seventh century not even the profoundest and acutest observer could have foreseen that in the heart of Arabia a religion was soon to arise and to result in the establishment of an Arab empire destined to give new shape to vast regions of the world, including the countries which had been the homes of the oldest civilisations. MOHAMMED The man whose energy gave clear and practical expression to the obscure impulse towards a purer religion arose amidst the worldly-wise Koreish. Flouted at first by his sober-minded fellow tribesmen, he gradually won the victory for his faith, and died the temporal and spiritual ruler of Arabia. To the very combination of qualities to some extent contradictory in his character, he owed his success with such a race as this. He firmly believed in his mission and was unscrupulous in his choice of means; he was a cataleptic visionary, and a great statesman; steadfast in his fundamental convictions and often weak and vacillating in details, he had great practical sagacity and was incapable of keen logical abstraction; he had a bias towards asceticism and a temperament strongly sensuous.
