Arab Conquest

In the seventh and eighth centuries AD, armies inspired by the new religion of Islam burst out of Arabia to subjugate the Levant, southwest Asia, North Africa and the Iberian peninsula. These Arab conquests followed immediately after the Prophet Mohammed's death in 632. By this time, against all the odds, he had managed to unite the feuding tribes of Arabia at the point of his sword. The Muslim conquests lasted until 750, by which time several generations of marauding Arab armies had carved out an Islamic empire which, in size and population, rivalled that of Rome at its zenith.

In just over a hundred years - from the death of Muhammad in 632 to the beginning of the Abbasid Caliphate in 750 - the followers of the Prophet swept across the whole of the Middle East, North Africa, and Spain. Their armies threatened states as far flung as the Franks in Western Europe and the Tang Empire in China. The conquered territory was larger than the Roman Empire at its greatest expansion, and it was claimed for the Arabs in roughly half the time.

Lost Enlightenment recounts how, between the years 800 and 1200, Central Asia led the world in trade and economic development, the size and sophistication of its cities, the refinement of its arts, and, above all, in the advancement of knowledge in many fields. Central Asians achieved signal breakthroughs in astronomy, mathematics, geology, medicine, chemistry, music, social science, philosophy, and theology, among other subjects.
