It is remarkable that after the decline of the old Semitic civilization, as exhibited in the Babylonian and Assyrian empires, the practical extinction of the Phoenicians, the conquest of Jerusalem, and the spread of the Jews over the whole world, there should have risen a new Semitic movement to disrupt and disorganize the world. It is interesting to note in this connection, also, that wherever the Arabs went they came in contact with learned Jews of high mentality, who co-operated with them in advancing learning.
The Rise and Expansion of the Arabian Empire.—Mohammedanism, which arose in the beginning of the seventh century, spread rapidly over the East and through northern Africa, and extended into Spain. All Arabia was converted to the Koran, and Persia and Egypt soon after came under its influence. In the period 623-640, Syria was conquered by the Mohammedans, upper Asia in 707, and Spain in 711. They established a great caliphate, extending from beyond the Euphrates through Egypt and northern Africa to the Pyrenees in Spain. They burned the great library at Alexandria, founded by Ptolemy, destroying the manuscripts and books in a relentless zeal to blot out all vestiges of Christian learning. In their passage westward they mingled with the Moors of northern Africa, whom they had subdued after various struggles, the last one ending in 709. In this year they crossed the Strait of Gibraltar and encountered the barbarians of the north.
The Visigothic monarchy was in a ruined condition. Frequent internal quarrels had led to the dismemberment of the government and the decay of all fortifications, hence there was little organized resistance to the incoming of the Arabs. All Spain, except in the far north in the mountains of the Asturias, was quickly reduced to the sway of the Arabs. They crossed the Pyrenees, and the broad territory of Gaul opened before them, awaiting their conquest. But on the plains between Tours and Poitiers they met Charles Martel with a strong army, who turned the tide of invasion back upon itself and set the limits of Mohammedan dominion in Europe.
In the tenth century the great Arabian Empire began to disintegrate. One after another of the great caliphates declined. The caliphate of Bagdad, which had existed so long in Oriental splendor, was first dismembered by the loss of Africa. The fatimate caliphate of northern Africa next lost its power, and the caliphate of Cordova, in Spain, brilliant in its ascendancy, followed the course of the other two. The Arabian conquest of Spain left the country in a state of tolerable freedom, but Cordova, like the others, was doomed to be destroyed by anarchy and confusion. All the principal cities became in the early part of the eleventh century independent principalities.
Thus the Mohammedan conquest, which built an extensive Arabian Empire, ruling first in Asia, then Africa, and finally Europe, spreading abroad with sudden and irresistible expansion, suddenly declined through internal dissensions and decay, having lasted but a few centuries. The peculiar tribal nature of the Arabian social order had not developed a strong central organization, nor permitted the practice of organized political effort on a large scale, so that the sudden transition from the small tribe, with its peculiar government, to that of the organization and management of a great empire was sufficient to cause the disintegration and downfall of the empire. So far as political power was concerned, the passion for conquest was the great impelling motive of the Mohammedans.
The Religious Zeal of the Arab-Moors.—The central idea of the Mohammedan conquest seems to have been a sort of religious zeal or fanaticism. The whole history of their conquest shows a continual strife to propagate their religious doctrine. The Arabians were a sober people, of vivid imagination and excessive idealism, with religious natures of a lofty and peculiar character. Their religious life in itself was awe-inspiring. Originally dwelling on the plains of Arabia, where nature manifested itself in strong characteristics, living in one sense a narrow life, the imagination had its full play, and the mystery of life had centred in a sort of wisdom and lore, which had accumulated through long generations of reflection. There always dwelt in the minds of this branch of the Semitic people a conception of the unity of God, and when the revelation of God came to them through Mohammed, when they realized "Allah is Allah, and Mohammed is his prophet," they were swept entirely away by this religious conception. When once this idea took firm hold upon the Arabian mind, it remained there a permanent part of life. Under military organization the conquest was rapidly extended over surrounding disintegrated tribes, and the strong unity of government built on the basis of religious zeal.
So strong was this religious zeal that it dominated their entire life. It turned a reflective and imaginative people, who had sought out the hidden mysteries of life by the acuteness of their own perception, to base their entire operations upon faith. Faith dominated the reason to such an extent that the deep and permanent foundations of progress could not be laid, and the vast opportunities granted to them by position and conquest gradually declined for the lack of vital principles of social order.
Not only had the Arabians laid the foundations of culture and learning through their own evolution, but they had borrowed much from other Oriental countries. Their contact with learning of the Far East, of Palestine, of Egypt, of the Greeks, and of the Italians, had given them an opportunity to absorb most of the elements of ancient culture. Having borrowed these products, they were able to combine them and use them in building an empire of learning in Spain. If their own subtle genius was not wanting in the combination of the knowledge of the ancients, and in its use in building up a system, neither lacked they in original conception, and on the early foundation they built up a superstructure of original knowledge. They advanced learning in various forms, and furnished means for the advancement of civilization in the west.
The Foundations of Science and Art.—In the old caliphates of Bagdad and Damascus there had developed great interest in learning. The foundation of this knowledge, as has been related, was derived from the Greeks and the Orientals. It is true that the Koran, which had been accepted by them as gospel and law, had aroused and inspired the Arabian mind to greater desires for knowledge. Their knowledge, however, could not be set by the limitations of the Koran, and the desire for achievement in learning was so great that scarcely a century had passed after the burning of the libraries of Alexandria before all branches of knowledge were eagerly cultivated by the Arabians. They ran a rapid course from the predominance of physical strength and courage, through blind adherence to faith, to the position of superior learning. The time soon came when the scholar was as much revered as the warrior.
In every conquered country the first duty of the conquerors was to build a mosque in which Allah might be worshipped and his prophet honored. Attached to this mosque was a school, where people were first taught to read and write and study the Koran. From this initial point they enlarged the study of science, literature, and art, which they pursued with great eagerness. Through the appreciation of these things they collected the treasures of art and learning wherever they could be found, and, dwelling upon these, they obtained the results of the culture of other nations and other generations. From imitation they passed to the field of creation, and advances were made in the contributions to the sum of human knowledge. In Spain schools were founded, great universities established, and libraries built which laid the permanent foundation of knowledge and art and enabled the Arab-Moors to advance in science, art, invention, and discovery.
