I use the word "Panislamism," simply because it is one of the political catchwords of the day. The prefix _Pan_ is supposed to have some great and terrible significance. It is not long since Europe exerted all her power to save Islam from the jaws of Panslavism, but now that a _Pan_ has been added to Islam, it has become in its turn the bugbear of Europe. It is even supposed that England was fighting with this new monster, when she put down the revolution in Egypt. England could never have so far forgotten her liberality as to take up arms against Islam, but Panislam must be crushed by a new crusade. Such is the wondrous power of a prefix. So far as I can understand the mysterious force of this word, it is designed to express the idea that the scattered fragments of the Mohammedan world have all rallied around the Caliph to join in a new attack upon Christendom, or that they are about to do so. There is just enough of truth in this idea to give it currency, and to make it desirable that the whole truth should be known. Most of the mistakes of Europe in dealing with the Ottoman empire, during the present century, have come from a misapprehension of the forces of Islam, and the position, and influence of the Sultan of Turkey. There is danger now of such a misapprehension as may lead to the most unfortunate complications. The first essential point, which must always be kept in mind by those who would understand the movements of the Mohammedan world, is the exact relation of the Ottoman Sultans to the Caliphate. The word Caliph means the vicar or the successor of the Prophet. The origin and history of the Caliphate is well known, but it may be well to give a brief _résumé_ of it here. During the life of the Prophet it was his custom to name a Caliph to act for him when he was absent from Medina. During his last illness he named his father-in-law, Abou-Bekir, and after his death this appointment was confirmed by election. Omar, Osman, and Ali were successively chosen to this office, and these four are recognized by all orthodox Mohammedans as perfect Caliphs. The Persians and other Shiites recognize only Ali. It is said that the Prophet predicted that the true Caliphate would continue only thirty years. His words are quoted: "The Caliphate after me will be for thirty years. After this there will be only powers established by force, usurpation, and tyranny." The death of Ali and the usurpation of Mouawiye came just thirty years after the death of the Prophet, and this was the end of the true and perfect Caliphate. The sixty-eight imperfect Caliphs who followed were all of the family of the Prophet, although of different branches, but they fulfilled the demand of the sacred law, that the Caliph must be of the family of Koreish, who was a direct descendant from Abraham. Mouawiye and the Ommiades, fourteen in all, were of the same branch as Osman, the third Caliph. The Abassides of Kufa, Bagdad, and Cairo, fifty-four in
