[Sidenote: Islam planted by aid of material force.] Such, then, was the nature of the Moslem propaganda, such the agency by which the faith was spread, and such the motives at once material and spiritual by which its martial missionaries were inspired. No wonder that the effete empires of Rome and Persia recoiled and quivered at the shock, and that province after province quickly fell under the sway of Islam. It is far from my intention to imply that the truths set forth by the new faith had nothing to do with its success. On the contrary, it may well be admitted that but for those truths success might have been impossible. The grand enunciation of the Divine Unity, and the duty of an absolute submission to the same; the recognition of a special providence reaching to the minutest details of life; the inculcation of prayer and other religious duties; the establishment of a code in which the leading principles of morality are enforced, and the acknowledgment of previous revelations in the Jewish and Christian Scriptures, told not only on the idolaters of Arabia and the fire-worshipers of Persia, but on Jews and Samaritans and the followers of a debased and priest-ridden Christianity. All this is true; but it is still not the less true that without the sword Islam would never have been planted even in Arabia, much less ever have spread to the countries beyond. The weapons of its warfare were "carnal," material, and earthly; and by them it conquered. [Sidenote: Alternatives offered to the conquered nations: Islam, the Sword, or Tribute.] The pressure brought to bear on the inhabitants of the countries overrun by Saracen arms was of the most stringent character. They were offered the triple alternative--Islam, the Sword, or Tribute. The first brought immediate relief. Acceptance of the faith not only stayed the enemy's hand, and conferred immunity from the perils of war, but associated the convert with his conquerors in the common brotherhood and in all the privileges of Islam.
