In the supreme command there was no hereditary succession. Abú Bekr was, as we have seen, chosen to be Caliph by the most influential Meccan Companions of the Prophet. Abú Bekr himself had finally nominated as his successor Omar, his right-hand man, and the second most intimate friend and counsellor of the Prophet. Omar, himself the ideal of a Moslem ruler, clearly thought none of his own companions quite worthy of the command. He arranged accordingly that after his death five of the most distinguished of the old friends of Mohammed should decide as to who among themselves ought to succeed. After long deliberation they united upon Othmán. Now Othmán had been, it is true, one of the very first to acknowledge Mohammed as a prophet, and he had successively married two daughters of the latter; but he belonged to the Omayyads, one of the most prominent families of pre-Islamite Mecca, the head of which, Abú Sufyán, had for years been leader in the struggle against Mohammed and the Medinites. Preference for kinsmen is deeply seated in the blood of every genuine Arab, and the Prophet himself was not free from it. Omar, who in many respects was a more consistent exponent of Islam than Mohammed, never laid himself open to the smallest charge of nepotism, but Othmán was a weak man; he showed exorbitant favour to his relatives, and in a short time a number of the most important and profitable posts were in the hands of Omayyads—able men for the most part, but of an intensely worldly disposition. The good Othmán was not himself conscious of anything wrong in this; but many of his subjects saw the matter in another light. The righteous indignation of some strict Moslems, the tumultuary disposition of the mass of the people, and very specially also the instigations of three of the five men who had formed the electoral college after Omar’s death,—Alí, Talha, and Zubair,—as also of Aïsha, daughter of Abú Bekr, and the intriguing favourite of the Prophet, resulted in a rebellion, in which the grey-headed Othmán was put to death (17th June 656). This deed of violence was an evil precedent for many subsequent scenes of terror, the beginning of bloody civil wars, and eventual schisms. The slayers of Othmán called Alí to the caliphate; Talha and Zubair also acknowledged him, but soon broke their word, and united with Aïsha against him. Alí’s bravery was soon a match for these enemies; but already another and more formidable opponent had arisen in the person of the astute Moáwiya, son of the Abú Sufyán mentioned above, who had long been governor of Syria, and held sway there like a prince. The struggle was carried on with animosity for years. Moáwiya came forward as avenger of his kinsman Othmán. As the powerful head of the family, he was, according to old Arab ideas, well entitled, and indeed bound to do this, and Islam had not abolished this view of his duty. But, as successor of Mohammed, the son of the man who
