From the prosperous period of the Abbásids onwards, freethinking spread to a considerable extent among the more highly-cultivated classes. Some poets ventured to ridicule or gainsay, more or less openly, fundamental doctrines of Islam, and even the faith itself. Persian writers expressed, in prose and verse, their detestation of Arabism; and the reflecting reader noted that the detestation extended to the Arab religion. One may imagine what expressions were used in conversation in such circles. The scholastic philosophers contrived for the most part to accommodate themselves outwardly to Islamite dogma, and often, we may be sure, in good faith; but the theologians nevertheless, and with reason, held them in deep suspicion; the old pagan Aristotle, on whom they leaned, fits in with Islam even less than with Christianity. All sorts of ideas—some of them very fantastic, of Persian and other foreign origin, and distinctly non-Islamite—also from time to time met with acceptance in the cultivated world. Once and again, indeed, a quite too audacious freethinker or heretic was executed; but in general people were allowed to speak and write freely, if only they put on a touch of Mohammedan varnish. Islam has no inquisition, and accepts as a Moslem the man who externally professes it, however doubtful his real sentiments may be. Accordingly, in some instances individuals whose thinking and teaching was quite un-Islamite, such as the famous mystic poet Abul-Alá al Maarrí (973-1057), were regarded by the people as devout, and even as saintly. But even from this very fact we can see that the danger for Islam was by no means very great. Such ideas were confined to very narrow circles of thinkers and poets, or of profligates, and were never long in dying out again. Nothing of it all penetrated to the great mass of the people, and it is in this that the strength of Islam lies.

The mysticism of the Súfis was a greater danger to the dominant religion. The impulse to self-mortification and introspection, which in Mohammed’s own case was very active at only one period of his life, found new nourishment after his followers had become masters of the neighbouring Christian countries, in which this type of piety was only too flourishing. It was all genuinely Semitic; and during the ascendency of the youthfully energetic element in Islam there was no danger of its exercising an enervating influence on the latter. But subsequently Persian and Indian ideas became associated with this mysticism. The Súfis sought to submerge themselves in God, and arrived at the Indian conception of the All-One, which is irreconcilable with Islam. In Indian fashion, systematic rules were devised for attaining the mystic victory over earthly limitations. He who believed himself to have succeeded in this might venture to break away from the precepts of positive religion, and often enough he allowed the moral law to go in the same way. The enthusiast, essentially a supernaturalist, who had merged himself in the All and One, readily held himself to be a worker of wonders; and still more easily was he so regarded by his adherents. What are the limits of the laws of nature (which Orientals, in fact, never recognise) to one who has effected the leap from the finite to the infinite? The finest and the coarsest attributes of the human spirit often worked together here. Amongst the Súfis we find deep souls, magnificent enthusiasts, fantastic dreamers, sensual poets, many fools, and many rogues. The systematic character of their procedure, which had to be learned, and the impression produced by the personality of leading Súfis, led to the formation of schools and orders. We have here a sort of monasticism, though without celibacy and without permanent vows. The fakírs or dervishes (i.e. “poor”) live on pious gifts or foundations, but often also carry on some civil calling. They keep up regular ascetic exercises, often of a very extraordinary character, in order to attain to the supersensuous. By these means they over-stimulate the nerves, exhaust body and spirit, and fall into a temporary insanity. However fine may be the blossoms which Súfic mysticism has produced, and however quickening its influence upon Persian poetry, the existence of dervishism, which plays a great part in almost all Mohammedan countries, is on the whole a mischief. For the rest, most Súfis believed themselves to be good Moslems. By allegorical interpretation they also were able to come to an understanding with the Koran. Not many can have clearly seen how fundamentally opposed is the pantheistic conception of God in mysticism to the rigid monotheism of the Koran. The great mass of dervishes are, of course, much too unthinking and superficial to follow in the fanciful footsteps of the old masters. They dance and howl for the glory of God, as other men pray. The people regard the dervishes as the props of Islam, and in fact hostility against all unbelievers is fomented in a quite special way by some of these brotherhoods. There is no suspicion how un-Islamic are the fundamental ideas on which these orders rest. The simple axioms of Islam itself meanwhile remain unshaken.

About the year 1000, Islam was in a very bad way. The Abbásid caliphate had long ceased to be of any importance, the power of the Arabs had long ago been broken. There was a multitude of Islamite States, great and small; but even the most powerful of these, that of the Fatimids, was very far from being able to give solidity to the whole, especially as it was Shíite. In fact, large regions which had been conquered by the first Caliphs were again lost to the Byzantines, who repeatedly penetrated far into Mohammedan territory. At this point a new element came to the aid of the religion, namely, the Turks. Warriors from Turkestan had long played a part in the history of Moslem kingdoms, but now there came a wholesale migration. The Turks pressed forward in great masses from their seats in upper Asia, and, newly converted to Islam, threw themselves in the first instance upon the lands of Persia. These nomads caused dreadful devastation, trampled to the ground the flourishing civilisation of vast territories, and contributed almost nothing to the culture of the human race; but they mightily strengthened the religion of Mohammed. The rude Turks took up with zeal the faith which was just within the reach of their intellectual powers, and they became its true, often fanatical, champions against the outside world. They founded the powerful empire of the Seljuks, and conquered new regions for Islam in the north-west. After the downfall of the Seljuk empire they still continued to be the ruling people in all its older portions. Had not the warlike character of Islam been revived by the Turks, the Crusaders perhaps might have had some prospect of more enduring success.

But this Turkish influx was followed by another of evil augury for Islam. Jenghiz Khan led his Mongols and Turks into Mohammedan territory in 1220, and his grandson Hulagu (January 1258) took Bagdad, the Mohammedan capital, and brought the Abbásid caliphate to an end. The loathly heathens were masters of Asia. But Islam, with its simple dogmas, its imposing ceremonial, and its practical character, soon won over these barbarians. Fifty years after the capture of Bagdad, those Mongols who had Moslem subjects had themselves accepted Islam. The frightful injuries they had inflicted on the lands of Islam were, however, not to be repaired. Babylonia, the home of primeval civilisation, was till then still the chief seat of Mohammedan culture; but since the Mongols set foot on it, it has been a desolation.

Through the dynasty of the Ottoman Turks, Islam once more became the terror of Christendom. The old dream of the conquest of Constantinople, and of the complete destruction of the Roman empire, was realised (1453). On his occupation of Egypt in 1517, Selím I. even proclaimed himself Caliph. The sultans of Egypt had, after the destruction of Bagdad, given their protection to a scion of the Abbásid family, to whom they gave the title of Caliph (1261), and similar nominal Caliphs, without any trace of power, “reigned” there till the Ottoman conquest. But how little the Moslem world troubled itself about them may be judged from the fact that the great philosophical historian Ibn Khaldún (of Tunis, 1332-1405), in the introduction to his History of the World, where he speaks very exhaustively about the caliphate, the spiritual and the secular State, never once alludes to this make-believe. But, armed with the enormous power of the then Turkish empire, the caliphate now once more bore another aspect. Although the sultan of Stamboul was wanting in one attribute which almost all orthodox teachers had regarded as essential in Caliphs, namely, descent from the Prophet’s tribe of Koraish, his claims found wide recognition, for his successes filled every Moslem heart with pride and joy, and the holy cities of Mecca, Medina, and Jerusalem did homage to him as their lord. The caliphate, let it be added, did not bring any actual increase of strength to the Ottoman sultans, who on the whole have not themselves attached much value to it; on their coins they do not assert the title either of “Caliph,” or “Imám,” or “Commander of the Faithful.” They have never actually possessed spiritual authority over Moslems who were not their own subjects. At the same time, it might be a serious thing for the Ottoman empire if the sultan should cease to be mentioned in public prayer at Mecca and Medina as overlord and Caliph, a thing which might very well happen if besides Egypt he were to lose Syria. For a kingdom that is slowly but steadily collapsing, the removal of even a weak pillar may be of disastrous consequence. It would appear that in the last confusions in Egypt prior to the English occupation, this idea was actually made use of, and alarm thereby excited in Constantinople. The Sherífs of Mecca as Caliphs (a suggestion that has been made) would, it must be said, play but a poor part. They are descended, indeed, from Alí, and thus theoretically have a vastly greater claim to the dignity than the Ottomans have; but their territory is small and excessively poor, and they of necessity could live only by the favour of other princes. Moreover, the heads of the different branches of this numerous family are constantly in conflict with each other in true Arabic fashion. Lastly, the sultans of Morocco have for a long time been also in the habit of calling themselves “Commanders of the Faithful,” and thus, for their own kingdom at least, they expressly lay claim to the supreme spiritual authority.

In the later Middle Ages the opposition between Sunnites and Shíites seemed to be dying down. The Sunnites had at an early period accepted certain Shíite views, particularly the exaggerated respect in which Alí was held, and on the other hand, all Shíites did not go so far as to declare Abú Bekr and Omar infidels. The Sherífs of Mecca, just spoken of, from being moderate Shíites had imperceptibly become Sunnites. But the enmity of the two parties received a new lease of life when, just about the time when the Sunnite Ottomans were attaining their highest power, a great empire arose also for the Shía. In Persia the doctrine of the divine right of Alí had of old fallen on specially fruitful soil; it is to Persian influences that the Shíite dogmas chiefly owe their development. In Persian lands smaller or greater Shíite States have also arisen at various times, but it was through the founding of the Sefid[[19]] empire (about 1500) that Persia first became in a strict sense the land of the Shíite faith, whilst formerly (what is often overlooked) it had been in great part Sunnite. This Shíite empire constituted a weighty counterpoise to the Ottomans, and through it many a diversion was created in favour of Europe when most distressed by the pressure of the Turks. Since the fall of the Sefids in last century, Persia has continued to sink deeper and deeper; the State and the nation are far feebler than even in Turkey; but Shíitism has taken Persia into its exclusive possession. So full of life is it, that even in our own time it was able to throw out a vigorous offshoot—the strange enthusiastic sect of the Bábís, which has profoundly agitated the entire country, and has not yet been definitively eradicated. The antithesis between Shía and Sunna is very sharp to this day. The Orientals, who have extraordinarily little feeling of patriotism, have all the more zeal for religion. Bitter hatred still separates the Persians from their Moslem neighbours,—Ottomans, Arabs, Uzbegs, Afghans, and so on,—because, forsooth, the Companions of Mohammed were not able to agree as to who should be the successor of the murdered Othmán.

Islam has, on the whole, undergone but little change during the last thousand years. The spread of mysticism and dervishism, as we have seen, did not affect the faith of the multitude. These things, of course, gave fresh stimulus to the business in saints and miracles. The mystic submerges himself in God, and ignores earthly things; the masses, accordingly, are only too much inclined to take for a saint the rogue who imitates him without scruple and seemingly surpasses him, and the madman who can make nothing of the world at all. Belief in miracles is deep-seated in the blood of the Oriental; religious impostors, themselves often the victims of imposition, have never been wanting there. That saints are able to work miracles, has been faintly questioned only by a few theologians. Of long time, accordingly, the real or alleged sepulchres of saints have been venerated as fountains of grace. They give rise to local cults, and often are hotbeds of fanaticism. It is no accident that in the last troubles in Egypt atrocities were perpetrated upon Europeans at the sepulchre of the most highly venerated of the Egyptian saints, es-Seyyid el Bedawí, at Tantá. Of holy places of this class many are of ancient Christian origin, and some even date from heathen times. All sorts of chicanery, crass superstition, and much that is totally un-Islamite easily connect themselves with such places. No Moslem, it is true, is under obligation to believe in any of these things; there is no such thing as an authoritative list of saints; and some Mohammedan scholars have even disputed the legitimacy of saint-worship altogether, but without success.

Towards the middle of last century there arose in the native land of Islam a violent storm of puritanism against the prevailing apostasy. The Wahhabites, or followers of Abdal-Wahháb, brought forward no new doctrine; they were thoroughly orthodox Moslems; but they broke with tradition thus far, that they sought to abolish certain abuses which had been tolerated or even approved by general consent. In this they proceeded with a strictness which reminds more of Omar than of the Prophet. They were far from denying Mohammed to have been the Apostle of God, but they held in detestation the exaggerated honour which was paid to his name, his dwelling-places, and his grave. The worship of saints they condemned as idolatry, and wherever they went they destroyed the saints’ tombs and places of martyrdom. They wanted to restore the original Islam; for example, they took in serious earnest the legal prohibition against the wearing of silk, and, in agreement with many learned theologians, interdicted tobacco as an innovation. The kingdom which they founded was a copy of the original Islamitic one; it once more reunited by force almost all the inhabitants of Arabia, but could not succeed in infusing a real spirit of religion into the great mass of the Bedouins. Their strict spiritual discipline was particularly irksome to the inhabitants of Mecca—on the whole a very secularly disposed people. The armies of Mohammed Alí of Egypt at length broke the power of the Wahhabites, not without great exertions, took back the sacred cities, Mecca and Medina, which had fallen into their hands in 1803, and penetrated into the heart of their kingdom (1814, 1815). They again took another start at a later period, but neither was this permanent; a purely Arab State, and that, too, founded upon religion, can be kept together for any length of time only by rulers of uncommon efficiency. At present the Wahhabite kingdom, properly so called, is powerless; it is subject to that of the Shammar, which lies to the north of it, and the prince of which, Ibn Rashíd, a ruler of extensive tracts, is also a professor of Wahhabitism, though with none of the fiery zeal of earlier times. The Wahhabites are no longer a menace to Damascus and Bagdad. Their reform of Islam has remained confined to Arabia, and even there is hardly likely to operate long. But it has rightly been remarked as noteworthy, that this purely Semitic religious movement with all its energy has produced nothing new; it has been directed exclusively towards the repristination of pure monotheism.

For a considerable time Islam has seemed to be in a state of deep humiliation. Even the great Moslem kingdoms are without strength. By far the larger portion of the Moslem world is ruled by Christian powers. But let us not deceive ourselves as to the vitality of this religion. How many catastrophes has it not already survived! Immediately on the death of its founder the revolt of the Arabs threatened it with extinction. Soon afterwards, from being a spiritual State (as corresponded with its essential nature), it was changed into a secular one, and it survived the transformation. Its united empire was broken up and fell into fragments. The Moslems tore one another to pieces in fierce party warfare. The Karmatians carried off the black stone, the palladium of Islam, and for years made impossible the pilgrimage, one of the most important expressions of Mohammedan life. The heathen Mongols destroyed the caliphate, and long ruled over half of the lands of Islam. Instead of being able to carry on the holy war against the unbeliever, one Moslem State after another is in these days either directly or indirectly falling under infidel control. But the faith that there is no God but Alláh, and that Mohammed is His Prophet, and all that is involved in this faith, remain unshattered. It would seem as if Islam were now in course of being driven out from the Balkan peninsula, even as it was long ago compelled to quit Sicily and Spain; whether it shall be able to maintain its hold everywhere in Asia and North Africa may be questioned; but in the Indian Archipelago it is steadily advancing, among the nomads of Central Asia it has gained strength just as the Russian sway has extended, and in Central Africa it is achieving conquest upon conquest. Precisely because the consolidation of European power in the lands of Nigritia brings with it greater security of intercourse, it may be presumed that the spread of Islam will be powerfully promoted there. But in the dark continent, which offers no favourable soil for Christianity, the acceptance even of Islam means progress from the deepest savagery to a certain culture, however limited and limiting, and to association with peoples who in the Middle Ages were higher in civilisation than the people of Europe. Perhaps slave-hunting and kidnapping will come to an end only when practically all the negro peoples shall have become Moslem.

If religion among the higher classes in Turkey is, undeniably, sometimes a matter of doubt or even of ridicule, more as the result of frivolity than as a consequence of serious thinking, and if similar phenomena manifest themselves still more frequently among the light-minded, bright, and unconscientious Persians, the firmness of the faith nevertheless remains unshaken with the vast mass of the people, even with those who are remiss in the discharge of ritual duties. Without any qualms of doubt, peacefully resigned to the will of God, the Moslem sees his kingdoms go down. But we must also be prepared to find the strength of this faith continuing to maintain itself in frightful outbursts of fanaticism. If the occurrences in Egypt during the last rebellion showed little of death-defying courage and energy, that is to be attributed to the languid temper of the Egyptians; a great rising in Syria or Asia Minor might conceivably give Europeans a good deal more trouble. The best strength of the great Indian Mutiny of 1856 lay with the Moslems. The Moslem subjects of Britain and other European States sigh for the moment when they shall be able to shake off the yoke of the infidel. The successes of the “dervishes” in the Soudan may serve to warn Europeans of the strength that still resides in the warrior zeal of Islam.
