The nations were the more rapidly subdued, since to the indomitable ferocity of the desert wanderer the Saracens added those other features which complete a warlike character. They despised death, and were self-denying and energetic to a degree far beyond the soldiers of civilized countries, while they were scarcely less familiar with the military art. The lieutenants of the caliphs soon vied with the Roman generals in skill; and it is by no means difficult to explain their almost uniform superiority, when we bear in mind the character of the armies they respectively commanded. Terror, moreover, is epidemic; and a force already successful commonly finds its victorious progress greatly aided by the prevailing notion of its prowess. Thus we have witnessed, {233} in the wars of more disciplined troops, the tremendous effect of a name alone. It may be added, also, that the Saracen success is greatly attributable to that ardent and impetuous spirit of religious enthusiasm with which they fought. They deemed their cause the cause of God; heaven, they were persuaded, was engaged in their behalf; every one who fell in their wars was a martyr; and cowardice was tantamount to apostacy. The religious ardour of the Crusaders, in the eleventh and twelfth centuries, to exterminate Mohammedanism, did not exceed, if it even equalled, that of the Arab soldiers by whom that system had been originally propagated. Whatever secular principles and ambition influenced them, they took credit for fighting in the support of truth and virtue. The sword and the Koran were equally the companions and the instruments of their wars. "The circumstance," says Paley, in his admirable exhibition of the Evidences of Christianity,[1] "that Mohammed's conquests should carry his religion along with them, will excite little surprise when we know the conditions which he proposed to the vanquished: death or conversion was the only choice offered to idolaters. To the Jews and Christians was left the somewhat milder {234} alternative of subjection and tribute if they persisted in their own religion, or of an equal participation of the rights and liberties, the honours and privileges of the faithful if they embraced the religion of their conquerors."
