History of Western Philosophy - Bertrand Russell [239]
The attacks upon the Eastern Empire, Africa, and Spain, differed from those of Northern barbarians on the West in two respects: first, the Eastern Empire survived till 1453, nearly a thousand years longer than the Western; second, the main attacks upon the Eastern Empire were made by Mohammedans, who did not become Christians after conquest, but developed an important civilization of their own.
The Hegira,1 with which the Mohammedan era begins, took place in A.D. 622; Mohammed died ten years later. Immediately after his death the Arab conquests began, and they proceeded with extraordinary rapidity. In the East, Syria was invaded in 634, and completely subdued within two years. In 637 Persia was invaded; in 650 its conquest was completed. India was invaded in 664; Constantinople was besieged in 669 (and again in 716–17). The westward movement was not quite so sudden. Egypt was conquered in 642, Carthage not till 697. Spain, except for a small corner in the north-west, was acquired in 711–12. Westward expansion (except in Sicily and Southern Italy) was brought to a standstill by the defeat of the Mohammedans at the battle of Tours in 732, just one hundred years after the death of the prophet. (The Ottoman Turks, who finally conquered Constantinople, belong to a later period than that with which we are now concerned.)
Various circumstances facilitated this expansion. Persia and the Eastern Empire were exhausted by their long wars. The Syrians, who were largely Nestorian, suffered persecution at the hands of the Catholics, whereas
Mohammedans tolerated all sects of Christians in return for the payment of tribute. Similarly in Egypt the Monophysites, who were the bulk of the population, welcomed the invaders. In Africa, the Arabs allied themselves with the Berbers, whom the Romans had never thoroughly subdued. Arabs and Berbers together invaded Spain, where they were helped by the Jews, whom the Visigoths had severely persecuted.
The religion of the Prophet was a simple monotheism, uncomplicated by the elaborate theology of the Trinity and the Incarnation. The Prophet made no claim to be divine, nor did his followers make such a claim on his behalf. He revived the Jewish prohibition of graven images, and forbade the use of wine. It was the duty of the faithful to conquer as much of the world as possible for Islam, but there was to be no persecution of Christians, Jews, or Zoroastrians—the 'people of the Book', as the Koran calls them, i.e. those who followed the teaching of a Scripture.
Arabia was largely desert, and was growing less and less capable of supporting its population. The first conquests of the Arabs began as mere raids for plunder, and only turned into permanent occupation after experience had shown the weakness of the enemy. Suddenly, in the course of some twenty years, men accustomed to all the hardships of a meagre existence on the fringe of the desert found themselves masters of some of the richest regions of the world, able to enjoy every luxury and to acquire all the refinements of an ancient civilization. They withstood the temptations of this transformation better than most of the Northern barbarians had done. As they had acquired their empire without much severe fighting, there had been little destruction, and the civil administration was kept on almost unchanged. Both in Persia and in the Byzantine Empire, the civil government had been highly organized. The Arab tribesmen, at first, understood nothing of its complications, and perforce accepted the services of the trained men whom they found in charge. These men, for the most part, showed no reluctance to serve under their new masters. Indeed, the change made their work easier, since taxation was lightened very considerably. The populations, moreover, in order to escape the tribute, very largely abandoned Christianity for Islam.
The Arab Empire was an absolute monarchy, under the caliph, who was the successor of the Prophet, and inherited much of his holiness. The caliphate was nominally elective, but soon became hereditary. The
