However, by the tenth century the Saracenic civilization began to display unmistakable symptoms of decline. This decline was at first gradual. Down to the terrible disasters of the thirteenth century it still displayed vigour and remained ahead of the Christian West. Still, by the year A.D. 1000 its golden age was over. For this there were several reasons. In the first place, that inveterate spirit of faction which has always been the bane of the Arab race soon reappeared once more. Rival clans strove for the headship of Islam, and their quarrels degenerated into bloody civil wars. In this fratricidal strife the fervour of the first days cooled, and saintly men like Abu Bekr and Omar, Islam's first standard-bearers, gave place to worldly minded leaders who regarded their position of "Khalifa"[1] as a means to despotic power and self-glorification. The seat of government was moved to Damascus in Syria, and afterward to Bagdad in Mesopotamia. The reason for this was obvious. In Mecca despotism was impossible. The fierce, free-born Arabs of the desert would tolerate no master, and their innate democracy had been sanctioned by the Prophet, who had explicitly declared that all Believers were brothers. The Meccan caliphate was a theocratic democracy. Abu Bekr and Omar were elected by the people, and held themselves responsible to public opinion, subject to the divine law as revealed by Mohammed in the Koran. But in Damascus, and still more in Bagdad, things were different. There the pure-blooded Arabs were only a handful among swarms of Syrian and Persian converts and "Neo-Arab" mixed-bloods. These people were filled with traditions of despotism and were quite ready to yield the caliphs obsequious obedience. The caliphs, in their turn, leaned more and more upon these complaisant subjects, drawing from their ranks courtiers, officials, and ultimately soldiers. Shocked and angered, the proud Arabs gradually returned to the desert, while the government fell into the well-worn ruts of traditional Oriental despotism. When the caliphate was moved to Bagdad after the founding of the Abbaside dynasty (A.D. 750), Persian influence became preponderant. The famous Caliph Haroun-al-Rashid, the hero of the _Arabian Nights_, was a typical Persian monarch, a true successor of Xerxes and Chosroes, and as different from Abu Bekr or Omar as it is possible to conceive. And, in Bagdad, as elsewhere, despotic power was fatal to its possessors. Under its blight the "successors" of Mohammed became capricious tyrants or degenerate harem puppets, whose nerveless hands were wholly incapable of guiding the great Moslem Empire.
